MJTP11936 Equivalent & Substitute Parts

Part Overview

The MJTP11936 is an illuminated tactile switch manufactured by APEM Inc., designed for applications requiring momentary contact switching at low voltage and current levels. This SPST-NO (Single Pole Single Throw - Normally Open) switch features a square button actuator with red LED illumination, top actuation orientation, and through-hole mounting. The part is Active in product status and maintains full RoHS3 compliance with unlimited moisture sensitivity rating.

Substitute parts are identified to provide design flexibility when the primary part is unavailable, when inventory constraints exist, or when application requirements permit alternative mechanical or electrical characteristics within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MJTP11936 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO to maintain identical electrical switching behavior
• Contact Rating: Must support 0.05A @ 12VDC minimum
• Switch Function: Must be Off-Mom (momentary contact)
• Mounting Type: Must be Through Hole for PCB compatibility
• Actuator Orientation: Must be Top Actuated for user interface consistency
• Termination Style: Must be PC Pin for solder connection compatibility
• Compliance: Must maintain RoHS3 compliance and REACH Unaffected status

The substitute part PTS125SK85-2 LFS (C&K) meets all mandatory electrical and mechanical criteria. Differences in actuator height, outline dimensions, operating force, and mechanical life rating do not preclude substitution when application requirements permit these variations.

Parameter Comparison

Engineering Selection Recommendations

Both the MJTP11936 and PTS125SK85-2 LFS are Active products with identical RoHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility for current and future applications.

The MJTP11936 is selected when illumination functionality is required, as it includes integrated red LED illumination at 2.1VDC. The PTS125SK85-2 LFS is a non-illuminated alternative suitable for applications where visual feedback is not needed or is provided through external indicators.

The PTS125SK85-2 LFS offers extended mechanical life (200,000 cycles versus 100,000 cycles) and wider low-temperature operating range (-40°C versus -20°C), making it suitable for high-cycle or cold-environment applications. The MJTP11936 maintains a more compact footprint (6.40mm x 6.20mm versus 12.00mm x 12.00mm) and lower actuator height (7.00mm versus 8.50mm), advantageous for space-constrained designs.

Selection between these parts depends on specific application requirements regarding illumination, mechanical life expectations, temperature operating range, and available PCB space.

Frequently Asked Questions (FAQ)

Q: Can the PTS125SK85-2 LFS replace the MJTP11936 in all applications?

A: Electrical substitution is valid for applications where illumination is not required. The PTS125SK85-2 LFS maintains identical circuit configuration (SPST-NO), contact rating (0.05A @ 12VDC), and switch function (Off-Mom). Mechanical differences include larger outline dimensions, increased actuator height, and higher operating force. PCB layout and user interface design must accommodate these differences.

Q: What are the key differences between these parts?

A: The MJTP11936 includes red LED illumination; the PTS125SK85-2 LFS does not. The PTS125SK85-2 LFS has a larger footprint, taller actuator, higher operating force (250gf versus 160gf), and extended mechanical life (200,000 versus 100,000 cycles). Operating temperature ranges differ: MJTP11936 operates -20°C to 70°C; PTS125SK85-2 LFS operates -40°C to 60°C.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the MJTP11936 and PTS125SK85-2 LFS are ROHS3 Compliant with REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: Does the difference in operating force affect compatibility?

A: Operating force difference (160gf versus 250gf) affects tactile feedback and user experience but does not affect electrical compatibility. Applications requiring specific actuation force characteristics must evaluate this parameter during design validation.

Q: Can the PTS125SK85-2 LFS be used in applications requiring the extended temperature range of the MJTP11936?

A: No. The PTS125SK85-2 LFS upper operating temperature limit is 60°C, while the MJTP11936 operates to 70°C. Applications requiring operation above 60°C must use the MJTP11936.
