PTS125VJM73 LFS Equivalent & Substitute Parts
Part Overview
The PTS125VJM73 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 component features side actuation, through-hole right-angle mounting, and a plunger actuator with polybutylene terephthalate (PBT) material. The product is currently obsolete, making identification of equivalent substitute parts essential for ongoing design support and component procurement.

Substitute Part Grouping Explanation
Substitution of the PTS125VJM73 LFS is determined by strict alignment of the following critical parameters:
- Circuit configuration: SPST-NO
- Switch function: Off-Mom (momentary operation)
- Contact rating: 0.05A @ 12VDC
- Mounting type: Through Hole, Right Angle
- Actuator type: Plunger for Cap
- Actuator orientation: Side Actuated
- Termination style: PC Pin
- Operating force: 160gf
- Illumination: Non-Illuminated
The substitute part TL1100CF160Q from E-Switch meets all these critical electrical and mechanical parameters, enabling direct functional equivalence in applications requiring this specific switch configuration.

Engineering Selection Recommendations
The TL1100CF160Q from E-Switch serves as the functional equivalent for the obsolete PTS125VJM73 LFS. Both components satisfy identical electrical specifications (SPST-NO, 0.05A @ 12VDC) and mechanical requirements (side-actuated plunger, through-hole right-angle mounting, 160gf operating force).
The TL1100CF160Q offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain equivalent RoHS and REACH compliance certifications, supporting regulatory requirements for new designs and legacy system maintenance.
Minor dimensional variations exist: the TL1100CF160Q actuator length is 6.45mm compared to 6.20mm on the original part, and the outline footprint differs slightly (12.00mm x 9.90mm versus 12.00mm x 12.00mm). The TL1100CF160Q operates across a broader temperature range (-20°C ~ 70°C) compared to the original (-40°C ~ 60°C), though the mechanical life specification is lower at 100,000 cycles versus 200,000 cycles.
Frequently Asked Questions (FAQ)
Q: Can the TL1100CF160Q directly replace the PTS125VJM73 LFS in existing designs?
A: The TL1100CF160Q matches all critical electrical and functional parameters (SPST-NO circuit, 0.05A @ 12VDC contact rating, momentary operation, 160gf operating force). PCB layout verification is required due to minor dimensional differences in actuator length and outline footprint.
Q: What are the key differences between these two parts?
A: The primary differences are actuator length (6.45mm versus 6.20mm), outline dimensions (12.00mm x 9.90mm versus 12.00mm x 12.00mm), operating temperature range (-20°C ~ 70°C versus -40°C ~ 60°C), and mechanical life (100,000 cycles versus 200,000 cycles). Electrical specifications and mounting characteristics are identical.
Q: Why is the PTS125VJM73 LFS obsolete?
A: The product status reflects manufacturer discontinuation. The TL1100CF160Q from E-Switch provides equivalent functionality with active product status and current manufacturing support.
Q: Are both parts RoHS and REACH compliant?
A: Yes. The PTS125VJM73 LFS is RoHS Compliant and REACH Unaffected. The TL1100CF160Q is ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards.
Q: What packaging is available for the substitute part?
A: The TL1100CF160Q is supplied in Bulk packaging, compared to the original part's standard packaging configuration.
