MJTP11933 Equivalent & Substitute Parts

Part Overview

The MJTP11933 is an illuminated tactile switch manufactured by APEM Inc., featuring SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration with a contact rating of 0.05A at 12VDC. This component is designed for through-hole mounting applications requiring tactile feedback with integrated LED illumination in green. The part is currently in active production status with 977 units available in inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across different manufacturer offerings, allowing for design flexibility, supply chain optimization, or inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MJTP11933 is determined by the following critical parameters:

• Circuit configuration must be SPST-NO
• Contact rating must support 0.05A @ 12VDC minimum
• Mounting type must be through-hole compatible
• Actuator orientation must be top-actuated
• Termination style must be PC pin
• RoHS3 compliance required
• Product status must be active

The PTS125SK85-2 LFS from C&K meets the core electrical and mechanical substitution criteria. However, design-level differences exist in physical dimensions, actuator height, operating force, and illumination characteristics that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the MJTP11933 and PTS125SK85-2 LFS are active production components with ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

The MJTP11933 provides integrated LED illumination (green, 2.1VDC nominal), making it suitable for applications requiring visual feedback. The PTS125SK85-2 LFS is a non-illuminated variant with larger physical footprint and higher mechanical life rating (200,000 cycles versus 100,000 cycles).

Selection between these parts depends on PCB layout constraints, illumination requirements, and mechanical durability expectations. The MJTP11933's compact 6.40mm x 6.20mm outline and lower actuator height (7.00mm) are advantageous for space-constrained designs. The PTS125SK85-2 LFS offers extended mechanical life and broader low-temperature operating range (-40°C minimum versus -20°C).

Frequently Asked Questions (FAQ)

Q: Can PTS125SK85-2 LFS directly replace MJTP11933 in existing designs?

A: Electrical substitution is possible due to matching SPST-NO circuit configuration and 0.05A @ 12VDC contact rating. However, physical differences require PCB layout verification: the PTS125SK85-2 LFS has a larger footprint (12.00mm x 12.00mm versus 6.40mm x 6.20mm) and taller actuator height (8.50mm versus 7.00mm). Loss of integrated LED illumination must be addressed separately if visual feedback is required.

Q: What are the key differences in mechanical performance?

A: The PTS125SK85-2 LFS requires higher operating force (250gf versus 160gf) and offers double the mechanical life (200,000 cycles versus 100,000 cycles). Operating temperature ranges differ: MJTP11933 operates -20°C to 70°C, while PTS125SK85-2 LFS operates -40°C to 60°C.

Q: Are both parts suitable for the same voltage and current applications?

A: Yes. Both parts are rated for 0.05A @ 12VDC contact rating and share identical SPST-NO circuit configuration, making them electrically compatible for the same switching applications.

Q: What compliance certifications apply to both parts?

A: Both MJTP11933 and PTS125SK85-2 LFS are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (unlimited moisture sensitivity level), meeting standard industrial component requirements.

Q: Does the illumination difference affect substitution feasibility?

A: The MJTP11933 includes integrated green LED illumination at 2.1VDC nominal, while PTS125SK85-2 LFS is non-illuminated. If visual feedback is required in the application, alternative illumination solutions must be implemented for the C&K part, or the APEM part should be retained.
