Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSC641G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part KSC641GLFS maintains identical specifications in circuit configuration (SPST-NO), contact rating (0.05A @ 32VDC), mounting type (surface mount), actuator characteristics (top actuated, 7.70mm height, 340gf operating force, 0.40mm travel), physical outline (6.20mm x 6.20mm), termination style (gull wing), ingress protection (IP67), operating temperature range (-40°C to 85°C), mechanical life (300,000 cycles), and moisture sensitivity level (MSL 1). The primary distinction between these parts is product status and packaging configuration, with KSC641GLFS supplied in Tape & Reel format and maintaining active product status with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The KSC641GLFS is the direct functional equivalent for the obsolete KSC641G. Both parts share identical electrical specifications, mechanical dimensions, and performance characteristics. The KSC641GLFS offers the advantage of active product status, ensuring continued availability and supply chain stability. Additionally, KSC641GLFS carries RoHS3 compliance, meeting current regulatory requirements for restricted substances in electrical and electronic equipment. For new designs or ongoing production requiring the KSC641G specification, KSC641GLFS is the appropriate selection. The Tape & Reel packaging of KSC641GLFS is standard for high-volume manufacturing and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can KSC641GLFS be used as a direct replacement for KSC641G in existing designs?
