MJTP1106S Equivalent & Substitute Parts

Part Overview

The MJTP1106S is an active SPST-NO tactile switch manufactured by APEM Inc., designed for surface mount applications with a rated contact capacity of 0.05A at 12VDC. This component is commonly used in control panels, consumer electronics, and industrial equipment where momentary switching functionality is required. The part is ROHS3 compliant and carries an MSL rating of 1 (Unlimited), indicating suitability for standard storage and handling conditions.

Equivalent and substitute parts are identified when component availability is constrained, supply chain disruptions occur, or design flexibility permits voltage and mechanical specification variations within acceptable operational parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MJTP1106S is determined by the following critical parameters:

Electrical Compatibility: The substitute part must maintain SPST-NO circuit configuration and momentary switch function. The contact rating voltage may vary (12VDC vs. 24VDC) provided the application circuit supports the higher voltage specification.

Mechanical Compatibility: Surface mount termination style (Gull Wing) and outline dimensions (6.00mm x 4.60mm) must remain constant to ensure PCB footprint compatibility. Actuator height variation within 0.27mm (4.30mm to 4.57mm) is acceptable for top-actuated rectangular button designs.

Operational Parameters: Operating force (180gf) and switch travel (0.25mm) must be identical. Mechanical life rating may differ; however, the substitute part must meet or exceed 20,000 cycles minimum.

Compliance Requirements: Both parts must maintain ROHS3 compliance and EAR99 ECCN classification. MSL rating differences do not preclude substitution when storage conditions are controlled.

The FSMSM part number from TE Connectivity ALCOSWITCH Switches meets these substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MJTP1106S): Select the MJTP1106S when the application operates at 12VDC nominal voltage and requires 100,000 cycle mechanical life rating. This part is active in production status with established supply availability.

Substitute Selection (FSMSM): The FSMSM is suitable as a substitute when:

• The application circuit operates at 24VDC or can accommodate higher voltage rating
• Mechanical life requirement does not exceed 20,000 cycles
• Extended operating temperature range (-35°C ~ 85°C) provides operational advantage
• PCB layout accommodates 0.27mm additional actuator height

Both parts maintain ROHS3 compliance and EAR99 classification, ensuring regulatory equivalence for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can the FSMSM replace the MJTP1106S in a 12VDC circuit?

A: Yes. The FSMSM is rated for 0.05A @ 24VDC, which exceeds the 12VDC requirement. A component rated for higher voltage is electrically compatible in lower voltage applications.

Q: What is the impact of the 0.27mm actuator height difference?

A: The FSMSM actuator height is 4.57mm compared to the MJTP1106S at 4.30mm. This difference must be evaluated against PCB clearance constraints, overlay geometry, and user interface design. Both parts maintain top-actuated rectangular button orientation.

Q: Does the lower mechanical life rating of the FSMSM affect substitution eligibility?

A: The FSMSM is rated for 20,000 cycles versus 100,000 cycles for the MJTP1106S. Substitution is valid only when the application duty cycle does not exceed 20,000 actuations. High-frequency switching applications require the MJTP1106S.

Q: Are there packaging or moisture sensitivity differences?

A: The MJTP1106S carries MSL 1 (Unlimited) rating. The FSMSM is rated as Not Applicable for MSL. Both parts are suitable for standard warehouse storage and handling. No special moisture control is required for either component.

Q: Can both parts be used interchangeably on the same PCB assembly?

A: PCB footprint compatibility is confirmed (6.00mm x 4.60mm outline, Gull Wing termination). However, the 0.27mm actuator height difference may affect overlay fit and user interface consistency. Design verification is necessary if both parts are used within the same product line.
