ALPS SKHH Series Alternative and Cross-Reference

Swiclick’s 6 x 6 mm through-hole tact switches are footprint-compatible alternatives to the ALPS Alpine SKHH series. The 6 x 6 snap-in tact is an industry-standard footprint, so the pad layout drops in; the variables to match are operating force, button height, and rated life. Two verified examples: the Swiclick KAN0611-0431B010-B42 matches a standard 4.3 mm, 160 gf SKHH variant at 100,000 cycles, and the long-life KAN0648A-0311A100-B42 runs 1,000,000 cycles at 100 gf, matching the high-life end of the SKHH range. Both are SPST, rated DC 12 V / 50 mA with contact resistance at or below 100 mOhm, and built under ISO 9001 and IATF 16949.

The SKHH series spans 0.98 to 5.1 N of force and 200,000 to 1,000,000 cycles across its heights, so the right match depends on the exact SKHH part number. Because the 6 x 6 footprint is standard, the practical path is to send the SKHH part number, receive the matching Swiclick sample, confirm height, force, and snap-in retention against the board, then move to volume. Swiclick 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 ALPS SKHH series, offered as a footprint-compatible alternative rather than a guaranteed drop-in, and is not affiliated with ALPS Alpine.

The ALPS SKHH series at a glance

The SKHH series is ALPS Alpine’s long-running 6 x 6 mm snap-in tact switch, a bestseller in user interfaces for decades. It is a through-hole, top-push and side-push switch with a sharp click feeling and short stroke. Standard button heights are 4.3, 5.0, 7.0, 9.5, 13.0, and 17.0 mm; operating force runs from 0.98 N (about 100 gf) to 5.1 N (about 520 gf); rated life spans 200,000 to 1,000,000 cycles; and the contact is a single SPST circuit rated DC 12 V / 50 mA. The SKHH is not dust- or water-resistant: ALPS uses the SKHU series for sealed versions and the SKHM series for a ground-terminal version. Common SKHH part numbers buyers cross-reference include SKHHLUA010, SKHHBSA010, SKHHASA010, and SKHHBKA010; each encodes a specific height, force, and life.

Swiclick cross-reference, verified parts

Two Swiclick parts anchor the cross-reference with values taken directly from their datasheets: a standard 6 x 6 part and a long-life 6 x 6 part that matches the 1,000,000-cycle end of the SKHH range.

By configuration, pick the Swiclick 6 x 6 part that matches the SKHH variant’s height and role:

Why teams second-source the SKHH series

ALPS Alpine parts are premium and, during allocation periods, can carry long lead times. Teams second-source the SKHH series for three reasons: unit cost on high-volume tact switches, lead-time security when the original is on allocation, and supply-chain resilience through a qualified dual source. Because the 6 x 6 footprint is standard, a footprint-compatible part lets a buyer keep the same board and qualify a second supplier without a redesign.

Matching the SKHH sharp click feel

The SKHH sharp feeling comes from a short stroke paired with a defined operating force; ALPS plots this as a feeling curve, where shorter travel at a given force gives a crisper click. Swiclick’s 6 x 6 tacts use the same short stroke, around 0.25 mm, so matching the feel is mainly a matter of matching the force point, 100, 160, or 260 gf, to the SKHH variant being replaced. The most reliable check is a sample pressed next to the original before committing to volume.

What matches, and what to verify

The pad layout is the easy part: the 6 x 6 snap-in footprint is standard, so a matching Swiclick 6 x 6 part mounts on the same lands. Three things decide a clean replacement, all from the specific SKHH part number: button height (pick the same standard height), operating force (match the force point), and rated life (for 1,000,000-cycle variants use the KAN0648A long-life part, not the standard one). Two items to confirm with a sample: whether the board relies on the SKHH snap-in retention bosses or only the solder legs, and whether the design needs the 2-pin or 4-pin terminal pattern. Swiclick ships free samples in 1 to 50 piece quantities within 4 days; standard production runs 7 to 15 working days.

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. Its 6 x 6 tact line is 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 height, force, and retention confirmed by sample before volume, never as pin-to-pin or drop-in replacements.
