Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PTS645VL58 is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary)
• Contact rating: 0.05A @ 12VDC
• Mounting type: Through Hole, Right Angle
• Actuator orientation: Side Actuated
• Termination style: PC Pin
• Mechanical life: 100,000 Cycles minimum

Secondary Compatibility Parameters:

• Actuator length: 5.85mm
• Outline dimensions: 7.50mm x 7.10mm (with tolerance for minor variations)
• Operating force: 130gf (with tolerance for minor variations)
• Actuator material: Polyamide or equivalent polymer

Substitute parts are grouped into two categories:

Direct Manufacturer Substitute: Parts from the same manufacturer (C&K) within the same product series that maintain identical electrical and mechanical specifications with improved product status or expanded operating temperature range.

Similar Manufacturer Substitute: Parts from alternative manufacturers (E-Switch) that meet all primary substitution criteria and maintain mechanical compatibility, though with minor variations in secondary parameters such as outline dimensions and operating force.

Engineering Selection Recommendations

PTS645VL58-2 LFS (Direct Manufacturer Substitute - Preferred)

The PTS645VL58-2 LFS is the primary recommended substitute. This part maintains identical electrical and mechanical specifications to the obsolete PTS645VL58 while offering active product status and improved operating temperature range (-40°C ~ 85°C versus -10°C ~ 60°C). Both parts are manufactured by C&K within the same product series, ensuring design continuity. The PTS645VL58-2 LFS carries ROHS3 compliance and is available in bulk packaging with substantial inventory (57,681 pieces in stock).

TL1105XF100Q (Similar Manufacturer Substitute - Alternative)

The TL1105XF100Q manufactured by E-Switch serves as an alternative substitute when PTS645VL58-2 LFS availability is constrained. This part meets all primary substitution criteria with identical circuit configuration, contact rating, switch function, mounting type, actuator orientation, and termination style. Minor variations exist in outline dimensions (7.10mm x 6.55mm versus 7.50mm x 7.10mm), operating force (100gf versus 130gf), and operating temperature range (-20°C ~ 70°C). The TL1105XF100Q is active in production with ROHS3 compliance and carries 1,080 pieces in current inventory.

Selection between these substitutes depends on application-specific requirements regarding operating temperature range, mechanical force tolerance, and PCB layout constraints related to outline dimensions.

Frequently Asked Questions (FAQ)

Q: Can PTS645VL58-2 LFS be used as a direct replacement for PTS645VL58?

A: Yes. The PTS645VL58-2 LFS maintains identical electrical specifications (0.05A @ 12VDC, SPST-NO configuration) and mechanical dimensions (7.50mm x 7.10mm outline, 5.85mm actuator length, 130gf operating force). Both parts feature side-actuated through-hole right-angle mounting with PC pin termination. The primary advantage of PTS645VL58-2 LFS is active product status and expanded operating temperature range (-40°C ~ 85°C).

Q: What are the key differences between PTS645VL58-2 LFS and TL1105XF100Q?

A: Both parts share identical circuit configuration (SPST-NO), contact rating (0.05A @ 12VDC), and switch function (Off-Mom). Differences include: manufacturer (C&K versus E-Switch), outline dimensions (7.50mm x 7.10mm versus 7.10mm x 6.55mm), operating force (130gf versus 100gf), and operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C). The TL1105XF100Q is suitable for applications where the reduced outline dimensions and lower operating force are compatible with design requirements.

Q: Are there packaging considerations when selecting a substitute?

A: PTS645VL58-2 LFS is available in bulk packaging, while the original PTS645VL58 was supplied with standard packaging. Both parts use identical PC pin termination and through-hole mounting, eliminating assembly process changes. Inventory availability differs significantly: PTS645VL58-2 LFS has 57,681 pieces in stock versus 906 pieces for the original part.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. Both PTS645VL58-2 LFS and TL1105XF100Q carry ROHS3 compliance and REACH Unaffected status, matching the regulatory requirements of the original PTS645VL58 (RoHS Compliant, REACH Unaffected). All parts maintain Moisture Sensitivity Level 1 (Unlimited).

Q: What is the mechanical life expectancy for substitute parts?

A: All parts in this comparison—PTS645VL58, PTS645VL58-2 LFS, and TL1105XF100Q—are rated for 100,000 mechanical cycles, ensuring equivalent durability and service life.
