Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSA0M412 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Contact rating (0.05A @ 32VDC)
• Switch function (Off-Mom momentary operation)
• Mounting type (Through Hole)
• Actuator orientation (Top Actuated)
• Actuator height (4.70mm)
• Outline dimensions (6.20mm x 6.20mm)
• Operating force (300gf)
• Ingress protection rating (IP65)
• Operating temperature range (-40°C ~ 85°C)
• Switch travel (0.60mm)
• Mechanical life (100,000 Cycles)
• Termination style (PC Pin)
• Series classification (KSA MKII)

The KSA0M412LFT meets all these parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The KSA0M412LFT is the direct substitute for the obsolete KSA0M412. Both components are electrically and mechanically identical across all functional parameters. The primary distinction is product status and regulatory compliance:

The KSA0M412 is obsolete and carries RoHS non-compliant status. The KSA0M412LFT is an active product with ROHS3 compliance, making it the appropriate selection for new designs and ongoing production requiring regulatory adherence. The KSA0M412LFT is available in bulk packaging with significantly higher inventory levels (8720 Pcs vs. 999 Pcs), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can KSA0M412LFT replace KSA0M412 in existing designs?

A: Yes. The KSA0M412LFT is electrically and mechanically equivalent to the KSA0M412 across all specified parameters, including circuit configuration, contact rating, mounting type, actuator geometry, and operating characteristics. Direct substitution is supported without design modification.

Q: What is the difference between KSA0M412 and KSA0M412LFT?

A: The components are functionally identical. The KSA0M412LFT differs in product status (Active vs. Obsolete), RoHS compliance (ROHS3 Compliant vs. non-compliant), and packaging format (Bulk vs. standard). The "LFT" designation indicates the lead-free, RoHS-compliant variant.

Q: Are there packaging considerations when switching to KSA0M412LFT?

A: The KSA0M412LFT is supplied in bulk packaging. Verify that bulk packaging meets your procurement and handling requirements. Both components share identical through-hole termination and PCB footprint specifications.

Q: What compliance certifications apply to these components?

A: The KSA0M412 is RoHS non-compliant and REACH Unaffected. The KSA0M412LFT is ROHS3 Compliant and REACH Unaffected. Both carry ECCN classification EAR99 and HTSUS code 8536.50.9031.

Q: Is the KSA0M412 still available?

A: The KSA0M412 is classified as obsolete. Current inventory is limited (999 Pcs). For new procurement, the KSA0M412LFT is recommended due to active product status and higher availability (8720 Pcs).
