PTS645VH15 Equivalent & Substitute Parts

Part Overview

The PTS645VH15 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 polyamide actuator. The product is currently obsolete, making equivalent substitutes necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PTS645VH15 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO
• Switch Function: Must be Off-Mom (Momentary)
• Contact Rating: Must support 0.05A @ 12VDC minimum
• Mounting Type: Must be Through Hole, Right Angle
• Actuator Orientation: Must be Side Actuated
• Termination Style: Must be PC Pin
• Mechanical Life: Must meet or exceed 100,000 Cycles
• Compliance: Must maintain RoHS and REACH compliance status

The TL1105QF160Q from E-Switch meets all mandatory substitution criteria, providing functional and mechanical compatibility with the obsolete PTS645VH15.

Parameter Comparison

Engineering Selection Recommendations

The TL1105QF160Q is a direct functional substitute for the obsolete PTS645VH15. Both components share identical circuit configuration, switch function, contact rating, mounting type, actuator orientation, and termination style. The substitute maintains equivalent mechanical life specifications and superior compliance certifications (ROHS3 vs. RoHS Compliant).

The TL1105QF160Q from E-Switch is an active product with established supply availability, providing design continuity for applications previously using the PTS645VH15. Both components are REACH Unaffected and classified under the same HTSUS code (8536.50.9031), confirming regulatory and commercial compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TL1105QF160Q directly replace the PTS645VH15 in existing designs?

A: Yes. Both components share identical circuit configuration (SPST-NO), switch function (Off-Mom), contact rating (0.05A @ 12VDC), mounting type (Through Hole, Right Angle), actuator orientation (Side Actuated), actuator length (15.85mm), and termination style (PC Pin). Mechanical life specifications are equivalent at 100,000 cycles.

Q: What are the dimensional differences between these parts?

A: The PTS645VH15 outline is 7.50mm x 7.10mm, while the TL1105QF160Q outline is 7.10mm x 6.55mm. Both maintain identical actuator length of 15.85mm for right-angle mounting. PCB footprint compatibility should be verified for the specific application.

Q: Are there operating temperature differences?

A: The PTS645VH15 operates from -10°C to 60°C, while the TL1105QF160Q operates from -20°C to 70°C. The substitute provides an extended operating temperature range suitable for broader environmental conditions.

Q: What is the difference in operating force?

A: The PTS645VH15 requires 200gf operating force, while the TL1105QF160Q requires 160gf. This difference may affect tactile feedback characteristics in user-facing applications.

Q: Are both components RoHS compliant?

A: Yes. The PTS645VH15 is RoHS Compliant, and the TL1105QF160Q is ROHS3 Compliant. Both meet current regulatory requirements and are REACH Unaffected.
