The Swiclick KAN0444-0201B1-29 is a footprint-compatible alternative to the XUNPU TS-1088-AR02016 tactile switch. Both are two-terminal SPST surface-mount tact switches on a 4 x 3 x 2 mm body with a 5 mm pad span, rated at 160 gf operating force, 0.2 mm travel, DC 12 V / 50 mA, and contact resistance at or below 100 mOhm.
The one specification to confirm is rated life. The KAN0444-0201B1-29 is rated at 50,000 operating cycles against 100,000 for the XUNPU part, so match it to the duty cycle of the application, or ask Swiclick about a higher-cycle build, since its tact line extends to 100,000 cycles and beyond. Everything else lines up, including the two-pad 5 mm land pattern, so the practical path is to request a free sample, confirm the footprint and feel against the design, then move to volume. Swiclick manufactures the KAN0444 factory-direct under ISO 9001 and IATF 16949 quality systems, ships free 1 to 50 piece samples in 4 days, and runs standard production in 7 to 15 working days. Swiclick is an independent alternative source for the XUNPU TS-1088-AR02016, offered as a footprint-compatible alternative rather than a guaranteed drop-in, and is not affiliated with XUNPU.
The XUNPU TS-1088-AR02016 at a glance
The XUNPU TS-1088-AR02016 is an ultra-small surface-mount tactile switch from Dongguan Xunpu Electronic Technology. It uses a round button actuator on a roughly 4.0 x 2.9 mm body with a 5.0 mm lead span and provides a single SPST contact. Published ratings are 160 gf operating force, about 0.2 mm travel, 100,000 operating cycles, DC 12 V at 50 mA, and contact resistance below 100 mOhm. It is a low-cost, high-volume catalog part, which is why design teams looking to second-source or cost-reduce it search for a matching alternative.

What matches, and what to verify
On size, footprint, feel, and electrical rating, the KAN0444-0201B1-29 matches the XUNPU part closely: a 4 x 3 x 2 mm body, a two-terminal SPST circuit, a 5 mm pad span, 160 gf operating force, 0.2 mm travel, DC 12 V / 50 mA rating, and initial contact resistance at or below 100 mOhm. The one real difference is rated life. The KAN0444 is specified at 50,000 operating cycles versus 100,000 for the XUNPU part. For light-to-moderate user inputs this is usually fine; for high-cycle interfaces, confirm the requirement or ask Swiclick about a higher-cycle build, since its tact range extends to 100,000 cycles and above. As with any second source, confirm the exact pad shape and footprint against the board with a free sample before releasing to volume.
How to second-source the XUNPU TS-1088-AR02016
The reliable way to qualify any alternative is to test the real part, not the datasheet. Swiclick ships free samples in 1 to 50 piece quantities within 4 days, so the path is: send the XUNPU part number and target quantity, receive KAN0444 samples, fit them to the board to confirm footprint and click feel, then release to volume. Standard production runs 7 to 15 working days. The KAN0444 is offered with or without a boss and in two height options, so if the design needs a different stem or a higher cycle life, Swiclick adjusts the build rather than force a fixed part.
How Swiclick supplies tact switches
Swiclick is a factory-direct manufacturer of precision miniature switches with 30+ years of in-house tooling and production across three plants in Shenzhen, Wenzhou, and Hubei. Tact switches, including the KAN0444 series, are built under ISO 9001 and IATF 16949 quality systems. Swiclick supplies cost-effective, footprint-compatible alternatives to catalog brands for cost-sensitive manufacturers, described honestly as alternatives with footprint and life confirmed by sample before volume, never as pin-to-pin or drop-in replacements.
FAQ
It is a footprint-compatible alternative, not a guaranteed drop-in. It matches the XUNPU part on body size (4 x 3 x 2 mm), two-terminal SPST circuit, 5 mm pad span, operating force (160 gf), travel (0.2 mm), rating (DC 12 V / 50 mA), and contact resistance (<=100 mOhm). The main difference is rated life, 50,000 versus 100,000 cycles. Confirm the footprint and life requirement with a free sample before volume.
The KAN0444-0201B1-29 is rated at 50,000 operating cycles; the XUNPU part is rated at 100,000. For light-to-moderate duty this is usually fine. For high-cycle inputs, confirm the requirement or ask Swiclick about a higher-cycle option, since its tact line extends to 100,000 cycles and above.
The XUNPU part is rated at 160 gf. The Swiclick KAN0444-0201B1-29 is rated at 160 +/- 50 gf, so the click feel is the same. Swiclick can also tune operating force if a different feel is required.
Yes. Swiclick ships free samples of 1 to 50 pieces within 4 days. Send the XUNPU part number and target quantity to start.
No. Swiclick is an independent manufacturer and an alternative source. XUNPU and TS-1088-AR02016 are referenced only for cross-reference and compatibility.
The KAN0444 is manufactured under ISO 9001 and IATF 16949 quality systems and is RoHS compliant.
