KSA0M332 Equivalent & Substitute Parts

Part Overview

The KSA0M332 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 designed for applications requiring momentary switching functionality. The KSA0M332 is currently listed as obsolete, making identification of compatible substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSA0M332 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Mounting type: Through Hole
• Actuator orientation: Top Actuated
• Outline dimensions: 6.20mm x 6.20mm
• Actuator height off PCB: 4.70mm
• Operating force: 130gf
• Switch travel: 0.50mm
• Mechanical life: 1,000,000 Cycles
• Operating temperature range: -40°C ~ 125°C
• Ingress protection: IP65
• Termination style: PC Pin
• Base product number: KSA0M3

Allowable Variation Parameter:

• Contact rating voltage: The substitute part KSA0M332LFT operates at 0.01A @ 32VDC, which represents a lower voltage rating than the original 50VDC specification. This substitution is valid for applications where the circuit voltage does not exceed 32VDC.

Parameter Comparison

Engineering Selection Recommendations

The KSA0M332LFT is the direct substitute for the obsolete KSA0M332. Both components share identical mechanical and functional specifications within the KSA MKII series. The primary distinction is the contact voltage rating: the substitute operates at 32VDC maximum versus the original 50VDC specification.

Compliance Advantage: The KSA0M332LFT carries ROHS3 compliance, whereas the original KSA0M332 is RoHS non-compliant. This compliance improvement supports regulatory requirements in applications subject to RoHS directives.

Product Availability: The KSA0M332LFT is currently in active production status with substantial inventory availability (4,678 pieces), compared to the obsolete status of the original part.

Substitution Validity: The KSA0M332LFT is suitable for direct replacement in applications where the circuit operating voltage does not exceed 32VDC. For applications requiring the full 50VDC rating of the original part, alternative components outside the provided substitute list must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the KSA0M332LFT replace the KSA0M332 in all applications?

A: The KSA0M332LFT is a direct mechanical and functional equivalent with one critical limitation: its contact voltage rating is 32VDC maximum, compared to the original 50VDC. Substitution is valid only for circuits operating at or below 32VDC. Applications requiring 50VDC operation require alternative components.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by matching circuit configuration (SPST-NO), switch function (Off-Mom), mounting type (Through Hole), actuator orientation (Top Actuated), outline dimensions (6.20mm x 6.20mm), actuator height (4.70mm), operating force (130gf), switch travel (0.50mm), mechanical life (1,000,000 cycles), operating temperature range (-40°C ~ 125°C), ingress protection (IP65), and termination style (PC Pin). The contact voltage rating may vary within specified limits.

Q: Does the KSA0M332LFT meet current regulatory requirements?

A: Yes. The KSA0M332LFT is ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The original KSA0M332 is RoHS non-compliant, making the substitute preferable for applications subject to RoHS directives.

Q: Are there packaging differences between the original and substitute parts?

A: The original KSA0M332 is listed with packaging designation "-" (not specified). The KSA0M332LFT is supplied in Bulk packaging. Both components use identical PC Pin termination and are suitable for through-hole PCB assembly.

Q: What is the mechanical life expectancy of the KSA0M332LFT?

A: Both the original and substitute parts are rated for 1,000,000 mechanical cycles, providing equivalent durability and operational lifespan.
