Parameter Comparison

Engineering Selection Recommendations

The LSA3K-2C serves as a direct functional equivalent to the LSYAB3K-2J across all critical electrical and mechanical parameters. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the HDLS series and maintain identical SPDT circuit configuration, current and voltage ratings, actuator characteristics, and mounting specifications.

The LSA3K-2C carries Active product status, providing continued availability and supply chain stability compared to the Obsolete LSYAB3K-2J. Both parts maintain RoHS Compliance and MSL 1 (Unlimited) ratings, ensuring equivalent environmental and handling compliance.

The operating temperature range of the LSA3K-2C (-12°C ~ 121°C) is narrower than the LSYAB3K-2J (-40°C ~ 121°C) at the lower temperature extreme. Applications requiring operation below -12°C require evaluation of this parameter difference.

Frequently Asked Questions (FAQ)

Q: Can the LSA3K-2C directly replace the LSYAB3K-2J in existing applications?

A: The LSA3K-2C is electrically and mechanically equivalent to the LSYAB3K-2J across all specified parameters including circuit configuration, current and voltage ratings, actuator type, mounting configuration, and termination style. Direct replacement is supported for applications operating within the LSA3K-2C temperature range of -12°C to 121°C.

Q: What is the difference in operating temperature range between these parts?

A: The LSYAB3K-2J operates from -40°C to 121°C, while the LSA3K-2C operates from -12°C to 121°C. The LSA3K-2C does not support operation below -12°C. Applications requiring low-temperature operation below -12°C must retain the LSYAB3K-2J or identify alternative components with extended low-temperature ratings.

Q: Are there packaging differences between the LSYAB3K-2J and LSA3K-2C?

A: The LSYAB3K-2J is supplied with standard packaging, while the LSA3K-2C is supplied in Bulk packaging. Both configurations contain identical components; packaging differences do not affect electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Both the LSYAB3K-2J and LSA3K-2C are RoHS Compliant and carry MSL 1 (Unlimited) ratings. Compliance certifications are equivalent between the two parts.

Q: Why is the LSYAB3K-2J listed as Obsolete?

A: The LSYAB3K-2J carries Obsolete product status, indicating it is no longer in active production. The LSA3K-2C, with Active product status, represents the current production equivalent and is the recommended selection for new designs and ongoing supply requirements.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts are rated for 10A AC at 120V and 800mA DC at 115V with identical SPDT (DB/DM) circuit configuration and On-Mom switch function.

Q: Are the mechanical specifications identical between these parts?

A: Yes. Both parts feature identical side rotary adjustable roller actuation, chassis mount configuration, screw terminal termination, nylon roller construction with front mounting, and identical operating force (46gfm), pretravel (15°), differential travel (5°), and overtravel (60°) specifications.
