Parameter Comparison

Engineering Selection Recommendations

The BK/S-8102-1-R is the direct functional equivalent and recommended substitute for the obsolete BK/S-8102-1. Selection is based on the following engineering criteria:

Electrical and Mechanical Equivalence: All critical parameters—voltage rating, current rating, fuse size, termination style, and circuit configuration—are identical between the two parts. Direct pin-for-pin and mechanical replacement is confirmed.

Product Status: The BK/S-8102-1-R is classified as active, ensuring ongoing availability, supply chain continuity, and manufacturer support. The original BK/S-8102-1 is obsolete and subject to discontinuation.

Regulatory Compliance: The BK/S-8102-1-R is ROHS3 compliant, meeting current environmental and regulatory standards. The original part is RoHS non-compliant. For new designs and systems subject to regulatory requirements, the BK/S-8102-1-R is the appropriate selection.

Inventory Availability: The BK/S-8102-1-R maintains higher stock levels (4955 Pcs) compared to the original part (1013 Pcs), supporting both immediate procurement and long-term supply security.

Frequently Asked Questions (FAQ)

Q: Can BK/S-8102-1-R be used as a direct replacement for BK/S-8102-1 in existing installations?

A: Yes. The BK/S-8102-1-R is electrically and mechanically identical to the BK/S-8102-1 across all functional parameters. Voltage rating, current rating, fuse size, mounting type, and termination style are equivalent, confirming direct replacement capability without circuit modification.

Q: What is the difference between BK/S-8102-1 and BK/S-8102-1-R?

A: The primary differences are product status and regulatory compliance. The BK/S-8102-1-R is an active product with ROHS3 compliance, while the BK/S-8102-1 is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Is the packaging different between these two parts?
