PTS635SL50 Equivalent & Substitute Parts
Part Overview
The PTS635SL50 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 top-actuated rectangular button actuation, through-hole mounting, and is designed for applications requiring momentary switching functionality. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing design support, maintenance, and production continuity.

Substitute Part Grouping Explanation
Substitution eligibility for the PTS635SL50 is determined by strict alignment of the following critical parameters:
Electrical Compatibility:
- Circuit configuration must be SPST-NO
- Switch function must be Off-Mom (momentary)
- Contact rating must support 0.05A @ 12VDC minimum
Mechanical Compatibility:
- Actuator type must be rectangular button
- Mounting type must be through hole
- Actuator height (vertical) must be 5.00mm
- Outline dimensions must be 6.00mm x 4.60mm
- Operating force must be 130gf

Engineering Selection Recommendations
The TL1107BF130WQ is a direct functional equivalent to the obsolete PTS635SL50. Both components share identical electrical specifications, mechanical dimensions, and actuator characteristics. The substitute part offers enhanced performance characteristics: an extended operating temperature range (-20°C ~ 70°C versus -40°C ~ 60°C) and increased mechanical life rating (50,000 cycles versus 20,000 cycles). Both components maintain equivalent regulatory compliance, with the substitute meeting ROHS3 standards. The substitute part is currently in active production status with substantial inventory availability, ensuring supply chain continuity for applications previously utilizing the PTS635SL50.
Frequently Asked Questions (FAQ)
Q: Can the TL1107BF130WQ be used as a direct replacement for the PTS635SL50 in existing designs?
A: Yes. Both components share identical electrical ratings (0.05A @ 12VDC), circuit configuration (SPST-NO), mechanical dimensions (6.00mm x 4.60mm outline, 5.00mm actuator height), and operating force (130gf). PCB footprints and through-hole pin configurations are compatible.
Q: What are the key differences between these two parts?
A: The primary differences are product status and performance ratings. The PTS635SL50 is obsolete, while the TL1107BF130WQ is in active production. The substitute offers a wider operating temperature range (-20°C ~ 70°C versus -40°C ~ 60°C) and higher mechanical life rating (50,000 cycles versus 20,000 cycles).
Q: Are there any packaging or supply considerations?
A: The PTS635SL50 is no longer manufactured. The TL1107BF130WQ is available in bulk packaging with substantial inventory levels (34,786 pieces in stock), providing reliable supply for new production and replacement applications.
Q: Do both parts meet the same regulatory requirements?
A: Both components are RoHS compliant and REACH unaffected. The substitute meets ROHS3 standards, which supersedes the RoHS compliance of the original part. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.
Q: Are the actuator materials compatible from a design perspective?
A: Both use polyamide materials (PA66 Nylon 6/6 for the original; PA46 Nylon 4/6 for the substitute). These materials provide equivalent mechanical properties and durability for the specified application parameters.
