PTS645TH50 Equivalent & Substitute Parts

Part Overview

The PTS645TH50 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 actuation, through-hole mounting, and a 6.00mm x 6.00mm outline with a 5.00mm actuator height. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PTS645TH50 is based on the following critical parameters that must remain consistent:

• Circuit configuration: SPST-NO
• Contact rating: 0.05A @ 12VDC
• Mounting type: Through Hole
• Actuator orientation: Top Actuated
• Outline dimensions: 6.00mm x 6.00mm
• Actuator height: 5.00mm
• Termination style: PC Pin
• Features: Grounding Pin

The TLE1105AF160Q from E-Switch meets these core electrical and mechanical requirements. While operating force and temperature range differ, these parameters fall within acceptable tolerance for equivalent functionality in the specified application category.

Parameter Comparison

Engineering Selection Recommendations

The TLE1105AF160Q is a direct functional equivalent for the obsolete PTS645TH50. Both components share identical electrical specifications (0.05A @ 12VDC, SPST-NO configuration) and mechanical form factors (6.00mm x 6.00mm outline, 5.00mm actuator height, through-hole mounting). The TLE1105AF160Q offers the advantage of active product status with current manufacturing availability, ensuring supply chain continuity.

The TLE1105AF160Q provides an extended operating temperature range (-20°C ~ 70°C versus -10°C ~ 60°C) and maintains equivalent mechanical life (100,000 cycles). Both components are RoHS compliant and feature grounding pins. The TLE1105AF160Q operates at 160gf versus the PTS645TH50's 200gf, representing a 20% reduction in actuation force that remains within acceptable engineering tolerance for standard tactile switch applications.

Frequently Asked Questions (FAQ)

Q: Can the TLE1105AF160Q directly replace the PTS645TH50 in existing PCB designs?

A: Yes. Both components share identical outline dimensions (6.00mm x 6.00mm), actuator height (5.00mm), through-hole mounting configuration, and PC pin termination. No PCB layout modifications are required.

Q: What is the significance of the 40gf operating force difference?

A: The PTS645TH50 requires 200gf actuation force while the TLE1105AF160Q requires 160gf. This 20% reduction in actuation force does not affect electrical performance or mechanical reliability for standard tactile switch applications. Both components maintain 100,000-cycle mechanical life ratings.

Q: Are there compliance differences between these components?

A: Both components are RoHS compliant. The TLE1105AF160Q carries ROHS3 certification while the PTS645TH50 is RoHS Compliant. Both are REACH Unaffected and classified as EAR99 for export control purposes.

Q: Does the extended temperature range of the TLE1105AF160Q affect compatibility?

A: No. The TLE1105AF160Q's operating range (-20°C ~ 70°C) encompasses the PTS645TH50's range (-10°C ~ 60°C). This extended capability provides additional design margin without introducing compatibility issues.

Q: What packaging considerations apply to the TLE1105AF160Q?

A: The TLE1105AF160Q is supplied in bulk packaging, whereas the PTS645TH50 was supplied with standard packaging. Verify bulk packaging compatibility with your procurement and assembly processes.
