KSA0M432 Equivalent & Substitute Parts

Part Overview

The KSA0M432 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 50VDC. This component features top actuation, through-hole mounting, and is rated for 100,000 mechanical cycles. The KSA0M432 is currently listed as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSA0M432 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Actuator type and orientation (Standard, Top Actuated)
• Mounting method (Through Hole)
• Physical footprint (6.20mm x 6.20mm outline, 4.70mm actuator height)
• Mechanical characteristics (300gf operating force, 0.60mm travel, 100,000 cycle life)
• Environmental rating (IP65 ingress protection, -40°C ~ 125°C operating range)
• Termination style (PC Pin)
• Series designation (KSA MKII)

The KSA0M432LFT meets all mechanical and functional equivalence criteria. The primary difference is the contact voltage rating: KSA0M432LFT is rated at 0.01A @ 32VDC compared to the original 0.01A @ 50VDC. This represents a reduced voltage specification, which is acceptable for applications operating at or below 32VDC.

Parameter Comparison

Engineering Selection Recommendations

The KSA0M432LFT is the direct substitute for the obsolete KSA0M432. Selection of KSA0M432LFT is appropriate when:

• The application operates at circuit voltages of 32VDC or below
• ROHS3 compliance is required for current production
• Active component availability and supply chain continuity are priorities
• Mechanical and functional performance requirements match the KSA MKII series specifications

For applications requiring the full 50VDC contact rating of the original KSA0M432, alternative tactile switch solutions outside the KSA MKII series must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can KSA0M432LFT be used as a direct replacement in all KSA0M432 applications?

A: KSA0M432LFT is mechanically and functionally equivalent to KSA0M432. The critical consideration is circuit voltage: if your application operates at 32VDC or below, KSA0M432LFT is a direct substitute. Applications requiring 50VDC operation require evaluation of alternative components.

Q: What is the primary difference between KSA0M432 and KSA0M432LFT?

A: The contact voltage rating differs: KSA0M432 is rated 0.01A @ 50VDC, while KSA0M432LFT is rated 0.01A @ 32VDC. All other mechanical, electrical, and environmental parameters are identical.

Q: Does KSA0M432LFT meet RoHS compliance requirements?

A: Yes. KSA0M432LFT is ROHS3 compliant, whereas the original KSA0M432 is RoHS non-compliant. This makes KSA0M432LFT suitable for applications with RoHS compliance mandates.

Q: Are the physical dimensions and PCB footprints identical?

A: Yes. Both parts share identical outline dimensions (6.20mm x 6.20mm), actuator height (4.70mm), and PC Pin termination. PCB layouts designed for KSA0M432 require no modification for KSA0M432LFT.

Q: What is the packaging difference?

A: KSA0M432 packaging is unspecified in available data. KSA0M432LFT is supplied in Bulk packaging.
