MJTP1193 Equivalent & Substitute Parts

Part Overview

The MJTP1193 is an active SPST-NO tactile switch manufactured by APEM Inc., designed for through-hole mounting applications requiring low-current switching at 12VDC. This component is specified for momentary operation with tactile feedback and is ROHS3 compliant. Substitute parts are identified to provide equivalent electrical functionality and mechanical compatibility for applications where the original part is unavailable or where design requirements permit alternative form factors.

Key Parameters

Substitute Part Grouping Explanation

The PTS125SK85-2 LFS manufactured by C&K qualifies as a substitute for the MJTP1193 based on the following critical parameters:

• Electrical Equivalence: Both parts share identical circuit configuration (SPST-NO) and contact rating (0.05A @ 12VDC), ensuring functional compatibility in switching applications.
• Mechanical Compatibility: Both employ through-hole mounting with PC pin termination and top-actuated orientation, permitting direct PCB layout substitution.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying environmental and moisture sensitivity requirements.
• Product Status: Both parts are active products with confirmed inventory availability.

Differences in actuator height (7.00mm vs. 8.50mm), outline dimensions (6.40mm x 6.20mm vs. 12.00mm x 12.00mm), operating force (160gf vs. 250gf), and mechanical life (100,000 vs. 200,000 cycles) represent design trade-offs that do not preclude substitution when application constraints permit.

Parameter Comparison

Engineering Selection Recommendations

Selection between MJTP1193 and PTS125SK85-2 LFS is determined by application-specific constraints:

MJTP1193 is preferred when:

• PCB space is constrained and compact form factor (6.40mm x 6.20mm) is required
• Lower actuator height (7.00mm) is necessary for enclosure fit
• Lower operating force (160gf) is specified for user interface requirements
• Operating temperature range of -20°C to 70°C satisfies application limits

PTS125SK85-2 LFS is preferred when:

• Extended mechanical life (200,000 cycles vs. 100,000 cycles) is required for high-cycle applications
• Higher operating force (250gf) is acceptable or desired for tactile feedback
• Larger outline dimensions (12.00mm x 12.00mm) do not conflict with PCB layout
• Extended low-temperature operation to -40°C is required

Both parts satisfy ROHS3 compliance and MSL 1 moisture sensitivity requirements. Product status is active for both manufacturers with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can PTS125SK85-2 LFS be used as a direct replacement for MJTP1193 on existing PCBs?

A: Electrical substitution is valid due to identical circuit configuration and contact rating. However, mechanical substitution requires PCB layout verification. The larger outline (12.00mm x 12.00mm vs. 6.40mm x 6.20mm) and increased actuator height (8.50mm vs. 7.00mm) must be confirmed against available PCB space and enclosure clearance.

Q: What are the key differences in operating characteristics?

A: Operating force differs (160gf vs. 250gf), affecting user actuation effort. Mechanical life is extended in the substitute (200,000 vs. 100,000 cycles). Operating temperature ranges differ slightly (-20°C to 70°C vs. -40°C to 60°C), with the substitute offering lower temperature capability but reduced upper temperature limit.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both MJTP1193 and PTS125SK85-2 LFS are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity level).

Q: Which part should be selected for high-cycle applications?

A: PTS125SK85-2 LFS is specified for 200,000 mechanical cycles compared to 100,000 cycles for MJTP1193, making it suitable for applications requiring extended operational life.

Q: Are there packaging considerations for these parts?

A: Both parts are supplied in bulk packaging. Inventory availability differs: MJTP1193 has 617 pieces in stock, while PTS125SK85-2 LFS has 5,765 pieces available.
