Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSL0M412 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 (9.90mm)
• Outline dimensions (7.40mm x 7.40mm)
• Operating force (300gf)
• Switch travel (0.60mm)
• Ingress protection rating (IP65)
• Operating temperature range (-40°C ~ 90°C)
• Mechanical life (100,000 Cycles)
• Termination style (PC Pin)
• Series classification (KSL MKII)

The KSL0M412LFT meets all these criteria and qualifies as a direct substitute. Differences in product status, packaging format, and RoHS compliance do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The KSL0M412LFT is the direct substitute for the obsolete KSL0M412. Both components are electrically and mechanically identical across all functional parameters. The primary distinction is product status: the KSL0M412 is obsolete, while the KSL0M412LFT maintains active production status.

For new designs or ongoing production requiring this switch type, the KSL0M412LFT is the appropriate selection. The KSL0M412LFT also provides improved compliance posture, meeting ROHS3 requirements compared to the non-compliant status of the original part.

Both components maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring regulatory consistency in supply chain applications.

Frequently Asked Questions (FAQ)

Q: Can the KSL0M412LFT be used as a direct replacement for the KSL0M412 in existing designs?

A: Yes. The KSL0M412LFT is electrically and mechanically identical to the KSL0M412 across all functional 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 the KSL0M412 and KSL0M412LFT?

A: The components are functionally equivalent. The KSL0M412 is obsolete, while the KSL0M412LFT is in active production. The KSL0M412LFT also carries ROHS3 compliance, whereas the KSL0M412 is RoHS non-compliant. Packaging differs (bulk for the LFT variant), but electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the KSL0M412LFT for the KSL0M412?

A: No compatibility concerns exist. Both components share identical through-hole mounting specifications, outline dimensions (7.40mm x 7.40mm), actuator height (9.90mm), and PC pin termination. PCB layout and footprint requirements remain unchanged.

Q: Does the KSL0M412LFT meet the same environmental and operational specifications?

A: Yes. Both components operate across the same temperature range (-40°C ~ 90°C), maintain identical IP65 ingress protection, and support 100,000 mechanical cycles. Operating force (300gf) and switch travel (0.60mm) are identical.

Q: What is the inventory status for these components?

A: The KSL0M412 has 1,152 pieces in stock (obsolete status). The KSL0M412LFT has 779 pieces in stock (active production). For new procurement, the KSL0M412LFT is the recommended source.
