KSF0M431LFT Equivalent & Substitute Parts

Part Overview

The KSF0M431LFT is a tactile switch manufactured by C&K, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a contact rating of 0.01A at 32VDC. This through-hole mounted component features top actuation, a 2.60mm actuator height, and is designed for applications requiring low-force tactile switching with 100,000 mechanical cycles. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSF0M431LFT is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Contact rating (0.01A @ 32VDC)
• Mounting type (Through Hole)
• Actuator height (2.60mm vertical)
• Actuator orientation (Top Actuated)
• Outline dimensions (7.40mm x 7.30mm)
• Operating force (300gf)
• Switch travel (0.30mm)
• Mechanical life (100,000 Cycles)
• Operating temperature range (-40°C ~ 125°C)
• Ingress protection (IP60)
• Termination style (PC Pin)

The KSF0M431 LFTR qualifies as a direct substitute based on identical electrical and mechanical specifications across all critical parameters. The primary distinction is packaging format and product status.

Parameter Comparison

Selection between these parts should be based on packaging requirements and supply chain availability. The KSF0M431 LFTR is supplied in bulk packaging, while the original part was supplied in tape and reel format.

Frequently Asked Questions (FAQ)

Q: Can the KSF0M431 LFTR be used as a direct replacement for the KSF0M431LFT?

A: Yes. Both components are electrically and mechanically identical across all critical parameters including circuit configuration, contact rating, mounting type, actuator dimensions, and operating characteristics. The substitution is valid for PCB assembly and design applications.

Q: What is the difference between the KSF0M431LFT and KSF0M431 LFTR?

A: The primary differences are product status and packaging format. The KSF0M431LFT is discontinued and was supplied in tape and reel packaging. The KSF0M431 LFTR is an active product supplied in bulk packaging. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components carry identical RoHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: What are the critical parameters that define substitution eligibility for this switch?

A: Substitution eligibility is determined by matching circuit configuration (SPST-NO), contact rating (0.01A @ 32VDC), mounting type (Through Hole), actuator height (2.60mm), actuator orientation (Top Actuated), outline dimensions (7.40mm x 7.30mm), operating force (300gf), switch travel (0.30mm), mechanical life (100,000 Cycles), and operating temperature range (-40°C ~ 125°C).

Q: Does packaging format affect electrical or mechanical performance?

A: No. Packaging format (tape and reel versus bulk) does not affect component performance. Selection should be based on assembly process requirements and supply chain logistics.
