PTS645TL70 Equivalent & Substitute Parts

Part Overview

The PTS645TL70 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 top-actuated design with a 6.00mm x 6.00mm outline and includes a grounding pin. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design requirements and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PTS645TL70 is determined by the following critical parameters:

• Circuit configuration must be SPST-NO
• Contact rating must support 0.05A @ 12VDC minimum
• Mounting type must be Through Hole
• Actuator height must be 7.00mm (vertical)
• Outline dimensions must be 6.00mm x 6.00mm
• Actuator orientation must be Top Actuated
• Termination style must be PC Pin
• Features must include Grounding Pin
• Mechanical life must meet or exceed 100,000 cycles

The TLE1105FF160Q from E-Switch meets all critical substitution criteria. While minor variations exist in operating force (160gf vs. 130gf) and operating temperature range (-20°C ~ 70°C vs. -10°C ~ 60°C), these differences remain within acceptable tolerance for equivalent component selection in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The TLE1105FF160Q is a direct functional equivalent for the obsolete PTS645TL70. Both components share identical electrical specifications, mechanical dimensions, and mounting characteristics. The TLE1105FF160Q carries Active product status, ensuring continued availability and supply chain reliability.

Compliance certifications are equivalent: both components are RoHS compliant (PTS645TL70 is RoHS Compliant; TLE1105FF160Q is ROHS3 Compliant), REACH Unaffected, and classified under ECCN EAR99. Both components maintain MSL 1 (Unlimited) moisture sensitivity rating.

The TLE1105FF160Q provides an extended operating temperature range (-20°C ~ 70°C compared to -10°C ~ 60°C) and slightly higher operating force (160gf compared to 130gf), offering enhanced performance margins for demanding applications without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TLE1105FF160Q be used as a direct replacement for the PTS645TL70?

A: Yes. Both components share identical circuit configuration (SPST-NO), contact rating (0.05A @ 12VDC), mounting type (Through Hole), physical dimensions (6.00mm x 6.00mm outline, 7.00mm actuator height), and termination style (PC Pin). Electrical and mechanical compatibility is confirmed.

Q: What are the differences between these two parts?

A: Operating force differs (130gf vs. 160gf) and operating temperature range is extended on the TLE1105FF160Q (-20°C ~ 70°C vs. -10°C ~ 60°C). The TLE1105FF160Q also includes a 0.25mm switch travel specification. These differences represent performance enhancements rather than incompatibilities.

Q: Why is the PTS645TL70 obsolete?

A: The PTS645TL70 is listed as obsolete by the manufacturer. The TLE1105FF160Q from E-Switch maintains Active product status, providing a sustainable alternative for new designs and component replenishment.

Q: Are there packaging differences?

A: The PTS645TL70 is packaged with a dash designation, while the TLE1105FF160Q is supplied in Bulk packaging. Both are suitable for through-hole PCB assembly.

Q: Do both parts meet RoHS requirements?

A: Yes. The PTS645TL70 is RoHS Compliant, and the TLE1105FF160Q is ROHS3 Compliant. Both satisfy current RoHS directives and are REACH Unaffected.
