Frequently Asked Questions (FAQ)

Q: Are the KSC441G70SH and KSC441G 70SH LFS electrically interchangeable?

A: Yes. Both parts are SPST-NO switches with identical contact ratings of 0.05A @ 32VDC, operating force of 400gf, and switch travel of 0.75mm. They function identically in circuit applications.

Q: What are the mechanical compatibility considerations?

A: Both parts share identical mechanical specifications: 6.20mm x 6.20mm outline, 5.20mm actuator height, gull wing termination, and top actuation. PCB footprints and assembly processes are compatible without modification.

Q: Why is the KSC441G 70SH LFS recommended over the original part?

A: The original KSC441G70SH is obsolete with no active production. The KSC441G 70SH LFS is an active product with superior regulatory compliance (ROHS3), ensuring long-term availability and meeting current environmental standards.

Q: Does packaging differ between these parts?

A: Yes. The KSC441G70SH is supplied in bulk packaging, while the KSC441G 70SH LFS is supplied in Tape & Reel format. Tape & Reel packaging is standard for automated surface mount assembly and reduces handling requirements.

Q: Are there any environmental or temperature limitations?

A: Both parts operate across the identical temperature range of -40°C to 85°C and maintain IP67 ingress protection. No environmental limitations differ between the two parts.

Q: What is the mechanical life expectancy?

A: Both the KSC441G70SH and KSC441G 70SH LFS are rated for 300,000 mechanical cycles, providing equivalent durability and service life.
