Engineering Selection Recommendations

The LSA3K-1A is a direct functional equivalent to the LSYAB3K2-5C for applications within the specified electrical and mechanical parameters. Selection between these parts should be based on the following factors:

Product Status Consideration: The LSYAB3K2-5C is obsolete, while LSA3K-1A is active. For new designs, ongoing production, or long-term supply requirements, LSA3K-1A is the appropriate selection.

Temperature Range Consideration: The LSYAB3K2-5C operates from -40°C to 121°C. The LSA3K-1A operates from -12°C to 121°C. Applications requiring operation below -12°C must retain the LSYAB3K2-5C or identify alternative solutions. Applications operating within -12°C to 121°C can use LSA3K-1A without thermal performance compromise.

Compliance and Certification: Both parts are RoHS Compliant with identical Moisture Sensitivity Level 1 ratings. Both carry ECCN EAR99 classification, supporting equivalent regulatory and export compliance profiles.

Packaging and Inventory: LSA3K-1A is available in Bulk packaging with 957 units in stock, compared to LSYAB3K2-5C with 864 units. LSA3K-1A provides superior supply availability for immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can LSA3K-1A directly replace LSYAB3K2-5C in existing designs?

A: LSA3K-1A is electrically and mechanically equivalent to LSYAB3K2-5C across all specified parameters: SPDT circuit, 10A AC / 800mA DC ratings, 120V AC / 115V DC operation, side rotary roller actuation, chassis mount configuration, and screw terminal termination. Direct replacement is supported for applications operating within -12°C to 121°C. Applications requiring operation below -12°C require design review.

Q: What is the primary difference between LSYAB3K2-5C and LSA3K-1A?

A: The primary differences are product status and operating temperature range. LSYAB3K2-5C is obsolete with -40°C minimum operating temperature. LSA3K-1A is active with -12°C minimum operating temperature. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: LSYAB3K2-5C is supplied with standard packaging (not specified). LSA3K-1A is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical performance.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both LSYAB3K2-5C and LSA3K-1A are RoHS Compliant with identical Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: Which part should be selected for new production?

A: LSA3K-1A should be selected for new production due to active product status and superior inventory availability. LSYAB3K2-5C is obsolete and should not be specified for new designs unless specific application constraints mandate its use.

Q: Are there any electrical performance differences?

A: No. Both parts operate at identical current ratings (10A AC, 800mA DC), voltage ratings (120V AC, 115V DC), and switch function (On-Mom). Electrical performance is equivalent.
