Key Parameters

Substitute Part Grouping Explanation

Substitution of the KSC441J70SH is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for circuit configuration, contact rating, actuator geometry, operating force, ingress protection rating, temperature range, switch travel distance, and mechanical life cycle rating.

The KSC441J 70SH LFS qualifies as a direct substitute based on the following key parameters:

• Circuit Configuration: SPST-NO (identical)
• Contact Rating: 0.05A @ 32VDC (identical)
• Mounting Type: Surface Mount (identical)
• Actuator Height: 5.20mm (identical)
• Outline Dimensions: 6.20mm x 6.20mm (identical)
• Operating Force: 400gf (identical)
• Ingress Protection: IP67 (identical)
• Operating Temperature: -40°C ~ 85°C (identical)
• Switch Travel: 0.75mm (identical)
• Mechanical Life: 300,000 Cycles (identical)
• Termination Style: J Lead (identical)
• Moisture Sensitivity Level: MSL 1 (identical)

Parameter Comparison

Engineering Selection Recommendations

The KSC441J 70SH LFS is the direct substitute for the obsolete KSC441J70SH. Both components are manufactured by C&K and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between the two parts is product status and regulatory compliance. The KSC441J70SH is obsolete, while the KSC441J 70SH LFS maintains active production status. Additionally, the KSC441J 70SH LFS achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain REACH Unaffected status and share the same ECCN and HTSUS classifications.

For new designs or ongoing production requiring this switch type, the KSC441J 70SH LFS is the appropriate selection due to its active availability and enhanced regulatory compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the KSC441J 70SH LFS be used as a direct replacement for the KSC441J70SH?

A: Yes. Both components share identical electrical and mechanical specifications, including circuit configuration, contact rating, actuator geometry, operating force, ingress protection, temperature range, and mechanical life. Direct substitution is supported without design modification.

Q: What is the primary reason to transition from KSC441J70SH to KSC441J 70SH LFS?

A: The KSC441J70SH is obsolete. The KSC441J 70SH LFS is the active equivalent from the same manufacturer with identical performance characteristics and improved regulatory compliance (ROHS3).

Q: Are there packaging differences between these parts?

A: The KSC441J70SH packaging specification is not provided. The KSC441J 70SH LFS is supplied in Cut Tape (CT) packaging. Confirm packaging requirements for your assembly process.

Q: Do both parts meet the same environmental and regulatory standards?

A: Both parts maintain REACH Unaffected status, share the same ECCN (EAR99) and HTSUS code (8536.50.9031), and operate across the identical temperature range (-40°C ~ 85°C). The KSC441J 70SH LFS additionally achieves ROHS3 compliance.

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

A: Substitution is determined by equivalence in circuit configuration (SPST-NO), contact rating (0.05A @ 32VDC), mounting type (Surface Mount), actuator height (5.20mm), outline dimensions (6.20mm x 6.20mm), operating force (400gf), ingress protection (IP67), operating temperature (-40°C ~ 85°C), switch travel (0.75mm), and mechanical life (300,000 cycles).
