The LSK6B-8C meets all substitution criteria and is classified as an active product, making it a direct equivalent for the obsolete LSYKB6B-8C.

Parameter Comparison

Engineering Selection Recommendations

The LSK6B-8C is a direct functional and mechanical equivalent to the obsolete LSYKB6B-8C. Both parts are manufactured by Honeywell Sensing and Productivity Solutions within the HDLS series and share identical electrical ratings, circuit configuration, and mechanical specifications.

Selection Basis:

The LSK6B-8C is recommended as the primary substitute based on:

1. Product Status: The LSK6B-8C is classified as active, ensuring ongoing availability and supply chain continuity compared to the obsolete LSYKB6B-8C.

2. Electrical Equivalence: Both parts maintain identical current ratings (10A AC / 800mA DC) and voltage ratings (120V AC / 115V DC), ensuring direct functional replacement in DPDT on-momentary switching applications.

3. Mechanical Compatibility: Identical actuator type, mounting configuration, termination style, operating force, and pretravel specifications confirm direct mechanical interchangeability.

4. Compliance: Both parts are RoHS Compliant with MSL Rating 1 (Unlimited), meeting environmental and moisture sensitivity requirements.

5. Temperature Operating Range: The LSK6B-8C operates within -12°C to 93°C, which is a subset of the original part's -29°C to 121°C range. Applications requiring the full extended temperature range of the original part should be evaluated against actual operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the LSK6B-8C be used as a direct replacement for the LSYKB6B-8C?

A: Yes. The LSK6B-8C is a direct equivalent. Both parts share identical electrical ratings, circuit configuration (DPDT), switch function (On-Momentary), actuator type, mounting type, and termination style. The LSK6B-8C is the active product alternative to the obsolete LSYKB6B-8C.

Q: What is the difference between the LSYKB6B-8C and LSK6B-8C?

A: The primary difference is product status. The LSYKB6B-8C is obsolete, while the LSK6B-8C is active. The LSK6B-8C has a narrower operating temperature range (-12°C to 93°C versus -29°C to 121°C). All other electrical and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: The LSYKB6B-8C is supplied with standard packaging, while the LSK6B-8C is supplied in bulk packaging. Both use plug-in termination and are suitable for chassis mount applications.

Q: Does the narrower temperature range of the LSK6B-8C affect compatibility?

A: The LSK6B-8C operates within -12°C to 93°C. Applications requiring operation below -12°C or above 93°C must be evaluated against actual system requirements. For applications within this range, the LSK6B-8C is fully compatible.

Q: Are both parts RoHS Compliant?

A: Yes. Both the LSYKB6B-8C and LSK6B-8C are RoHS Compliant with MSL Rating 1 (Unlimited), meeting environmental and moisture sensitivity standards.

Q: What is the current availability of these parts?

A: The LSK6B-8C is the active product with 1134 pieces in stock. The LSYKB6B-8C is obsolete with 619 pieces remaining in inventory. For new designs and ongoing procurement, the LSK6B-8C should be specified.
