Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PTS635VL31 LFS is determined by the following critical parameters:

Electrical Compatibility: Circuit configuration (SPST-NO), switch function (Off-Mom), and contact rating (0.05A @ 12VDC) must match exactly.

Mechanical Compatibility: Mounting type (Through Hole, Right Angle), actuator orientation (Side Actuated), termination style (PC Pin), and outline dimensions (6.00mm x 4.60mm) must be identical to ensure PCB fit and assembly compatibility.

Environmental Compliance: RoHS compliance status and REACH classification must be maintained or improved.

The MJTP1117 from APEM Inc. satisfies these core substitution criteria while offering enhanced performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The MJTP1117 is a direct functional substitute for the PTS635VL31 LFS. Both components share identical electrical specifications, mechanical mounting characteristics, and outline dimensions, ensuring drop-in compatibility at the PCB level.

The MJTP1117 offers the following advantages:

Product Availability: Active product status ensures long-term supply chain reliability and continued manufacturer support, eliminating obsolescence risk associated with the PTS635VL31 LFS.

Regulatory Compliance: ROHS3 compliance exceeds the RoHS Compliant status of the original component, meeting current and future regulatory requirements.

Enhanced Durability: Mechanical life rating of 100,000 cycles compared to 20,000 cycles provides extended operational longevity.

Extended Temperature Range: Operating temperature range of -20°C ~ 70°C covers the original -40°C ~ 60°C specification, with extended upper temperature capability.

Frequently Asked Questions (FAQ)

Q: Can the MJTP1117 be used as a direct replacement for the PTS635VL31 LFS?

A: Yes. Both components share identical circuit configuration (SPST-NO), contact rating (0.05A @ 12VDC), mounting type (Through Hole, Right Angle), actuator orientation (Side Actuated), termination style (PC Pin), and outline dimensions (6.00mm x 4.60mm). No PCB modifications are required.

Q: What are the key differences between these two components?

A: The primary differences are product status (Obsolete vs. Active), mechanical life rating (20,000 vs. 100,000 cycles), operating temperature range (-40°C ~ 60°C vs. -20°C ~ 70°C), and regulatory compliance level (RoHS Compliant vs. ROHS3 Compliant).

Q: Are there any compatibility concerns with the MJTP1117 in existing designs?

A: No compatibility concerns exist. The MJTP1117 maintains identical electrical and mechanical specifications required for substitution. The extended mechanical life and improved temperature range represent performance enhancements rather than deviations.

Q: What is the packaging format for the MJTP1117?

A: The MJTP1117 is supplied in Bulk packaging, compared to the original component's standard packaging format.

Q: Does the MJTP1117 meet current regulatory requirements?

A: Yes. The MJTP1117 carries ROHS3 Compliant and REACH Unaffected certifications, meeting current environmental and chemical safety regulations.
