Substitute Part Grouping Explanation

Substitution of the KSC411J 70 SH is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part KSC411J 70SH LFS maintains identical specifications for circuit configuration, contact rating, mounting type, actuator geometry, operating force, switch travel, ingress protection rating, operating temperature range, mechanical life rating, and termination style. The primary distinction between the main part and its substitute is packaging format and product status. The KSC411J 70SH LFS is supplied in Tape & Reel (TR) packaging and maintains active product status, whereas the original KSC411J 70 SH is obsolete. Both parts share the same base product number (KSC411) and series designation, confirming functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The KSC411J 70SH LFS is the direct functional equivalent for the obsolete KSC411J 70 SH. Selection of the substitute part is justified by complete parameter equivalence across all electrical and mechanical specifications. The KSC411J 70SH LFS offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The substitute part also achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain identical REACH and ECCN classifications. The packaging difference (Tape & Reel versus bulk) reflects standard industry practice for active production parts and does not affect functional performance or PCB assembly compatibility. Inventory availability is significantly higher for the substitute part (27,179 units versus 972 units), supporting long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Are the KSC411J 70 SH and KSC411J 70SH LFS electrically identical?

A: Yes. Both parts share identical circuit configuration (SPST-NO), contact rating (0.05A @ 32VDC), operating force (140gf), switch travel (0.35mm), and mechanical life rating (1,000,000 cycles). They are electrically equivalent.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. The KSC411J 70 SH is obsolete and supplied in bulk packaging. The KSC411J 70SH LFS is an active product supplied in Tape & Reel (TR) format and achieves ROHS3 compliance. All functional parameters are identical.

Q: Can the KSC411J 70SH LFS be used as a direct replacement on existing PCBs designed for the KSC411J 70 SH?

A: Yes. Both parts have identical surface mount footprints (6.20mm x 6.20mm outline), actuator height (5.20mm), and J Lead termination style. No PCB redesign is required.

Q: Does the Tape & Reel packaging affect assembly compatibility?

A: No. Tape & Reel packaging is standard for surface mount component assembly and is compatible with automated pick-and-place equipment. The component itself is identical to bulk-packaged versions.

Q: What is the inventory status for each part?

A: The KSC411J 70 SH has 972 units in stock. The KSC411J 70SH LFS has 27,179 units in stock, providing significantly greater availability for production requirements.

Q: Are there any compliance differences between these parts?

A: The KSC411J 70SH LFS is ROHS3 compliant, while the KSC411J 70 SH is RoHS non-compliant. Both parts are REACH Unaffected and share the same ECCN classification (EAR99).
