MJTP1232G Equivalent & Substitute Parts

Part Overview

The MJTP1232G is an active tactile switch manufactured by APEM Inc., configured as a SPST-NO (Single Pole Single Throw - Normally Open) momentary contact switch. This component is rated for 0.05A at 12VDC and features top-actuated through-hole mounting with a 6.00mm x 6.00mm footprint. The switch delivers tactile feedback with 160gf operating force and supports 100,000 mechanical cycles. ROHS3 compliance and MSL 1 rating ensure compatibility with modern manufacturing processes. Substitute parts are identified when electrical ratings, mechanical dimensions, and functional characteristics align with the original specification, enabling direct replacement in applications where component availability or supply chain considerations necessitate alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MJTP1232G is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary contact)
• Contact rating: 0.05A @ 12VDC
• Mounting type: Through Hole
• Actuator orientation: Top Actuated
• Outline dimensions: 6.00mm x 6.00mm
• Actuator height off PCB: 7.00mm
• Termination style: PC Pin
• Mechanical life: 100,000 Cycles
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

The substitute parts PTS645TK70-2 LFS and PTS645TM70-2 LFS, both manufactured by C&K, satisfy all mandatory electrical and mechanical parameters. Both parts maintain identical circuit configuration, voltage/current ratings, mounting geometry, and compliance certifications. Variations in operating force (260gf for PTS645TK70-2 LFS versus 160gf for PTS645TM70-2 LFS) and operating temperature range (-40°C ~ 85°C for both C&K parts versus -20°C ~ 70°C for MJTP1232G) represent secondary characteristics that do not preclude substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

Both C&K substitute parts maintain active product status and full ROHS3 compliance with MSL 1 rating, ensuring compatibility with current manufacturing and assembly processes. PTS645TM70-2 LFS provides the closest functional match to MJTP1232G, maintaining identical 160gf operating force while offering extended operating temperature range (-40°C ~ 85°C). PTS645TK70-2 LFS operates at 260gf, representing increased actuator resistance; this variant is suitable for applications where higher actuation force is acceptable or beneficial. Both C&K parts include grounding pin features not present in the MJTP1232G. Selection between substitute options depends on application-specific requirements regarding operating force and temperature operating envelope.

Frequently Asked Questions (FAQ)

Q: Can PTS645TK70-2 LFS replace MJTP1232G in all applications?

A: PTS645TK70-2 LFS satisfies all mandatory electrical and mechanical parameters for direct substitution. The 260gf operating force (versus 160gf in MJTP1232G) represents the primary functional difference. Substitution is valid when application design accommodates or benefits from increased actuation force.

Q: What is the significance of the grounding pin feature in C&K substitute parts?

A: The grounding pin is a structural feature present in PTS645TK70-2 LFS and PTS645TM70-2 LFS but not specified in MJTP1232G. This feature does not prevent substitution and may provide additional mechanical stability in applications where grounding is beneficial.

Q: Are the C&K substitute parts pin-compatible with MJTP1232G?

A: Yes. Both substitute parts use PC Pin termination style with identical 6.00mm x 6.00mm outline and 7.00mm actuator height, ensuring direct PCB footprint compatibility.

Q: How do operating temperature ranges affect substitution decisions?

A: MJTP1232G operates within -20°C ~ 70°C, while both C&K substitutes operate within -40°C ~ 85°C. Applications operating within the MJTP1232G temperature envelope are fully compatible with either substitute. Applications requiring extended temperature operation benefit from C&K parts.

Q: Which substitute part should be selected for new designs?

A: PTS645TM70-2 LFS is recommended for new designs requiring direct functional equivalence to MJTP1232G, as it maintains identical 160gf operating force while providing extended temperature range and active product status. PTS645TK70-2 LFS is suitable when higher operating force is specified or preferred.
