PTS645TH50 LFS Equivalent & Substitute Parts

Part Overview

The PTS645TH50 LFS is a tactile switch manufactured by C&K, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a contact rating of 0.05A at 12VDC. This through-hole mounted component features a 6.00mm x 6.00mm outline with top actuation and a 5.00mm actuator height. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where legacy component compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PTS645TH50 LFS is determined by strict alignment with the following critical parameters:

• Circuit configuration: SPST-NO
• Contact rating: 0.05A @ 12VDC
• Mounting type: Through Hole
• Outline dimensions: 6.00mm x 6.00mm
• Actuator orientation: Top Actuated
• Termination style: PC Pin
• Mechanical life: 100,000 Cycles minimum
• RoHS compliance: ROHS3 Compliant

The MJTP1232A from APEM Inc. meets all mandatory electrical and mechanical parameters for direct substitution. Both components share identical circuit configuration, contact rating, mounting type, outline dimensions, actuator orientation, and termination style. Both achieve the required 100,000 cycle mechanical life specification and maintain ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The MJTP1232A is a direct functional equivalent to the PTS645TH50 LFS for applications requiring SPST-NO tactile switching at 0.05A and 12VDC. Both components satisfy identical electrical specifications, mechanical dimensions, and regulatory compliance requirements.

The primary distinction is product status: the PTS645TH50 LFS is obsolete, while the MJTP1232A maintains active production status. For new designs or systems requiring long-term component availability, the MJTP1232A is the appropriate selection. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can the MJTP1232A directly replace the PTS645TH50 LFS in existing PCB designs?

A: Yes. Both components share identical outline dimensions (6.00mm x 6.00mm), actuator height (5.00mm), PC pin termination, and top actuation orientation. PCB footprints designed for the PTS645TH50 LFS accommodate the MJTP1232A without modification.

Q: Are the electrical specifications identical between these components?

A: Yes. Both components are rated for 0.05A at 12VDC with SPST-NO circuit configuration. Both achieve 100,000 cycle mechanical life and maintain identical contact rating specifications.

Q: What is the significance of the product status difference?

A: The PTS645TH50 LFS is obsolete and no longer manufactured. The MJTP1232A is in active production. For applications requiring component replenishment or new system designs, the MJTP1232A ensures ongoing availability and supply chain continuity.

Q: Do both components meet the same regulatory standards?

A: Yes. Both the PTS645TH50 LFS and MJTP1232A are ROHS3 compliant and REACH unaffected, meeting current electronic component regulatory requirements.

Q: Are there differences in operating temperature ranges?

A: Yes. The PTS645TH50 LFS operates across -40°C to 85°C, while the MJTP1232A operates across -20°C to 70°C. For applications requiring operation below -20°C or above 70°C, the PTS645TH50 LFS specification must be maintained if available through alternative sourcing channels.
