Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSYAC3KQ-FP-C is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPDT DB/DM), current ratings (7A AC / 800mA DC), and voltage ratings (120V AC / 115V DC) must be identical.

Mechanical Parameters: Actuator type (side rotary without lever), mounting configuration (chassis mount), and termination style (connector) must match exactly.

Environmental Parameters: Ingress protection rating (IP67), operating temperature range (-12°C to 121°C), and mechanical specifications (operating force 46gfm, pretravel 15°, differential travel 5°, overtravel 60°) must be maintained.

Compliance Parameters: RoHS compliance and MSL rating (1 - Unlimited) must be preserved.

Substitute parts are grouped based on identical parameter values across all these categories. Packaging differences alone do not disqualify substitution eligibility when all electrical, mechanical, and environmental specifications are equivalent.

Parameter Comparison

Engineering Selection Recommendations

The LSYAC3KQ-FP serves as a direct functional equivalent to the obsolete LSYAC3KQ-FP-C. Both components are manufactured by Honeywell Sensing and Productivity Solutions and maintain identical electrical, mechanical, and environmental specifications across all critical parameters.

Product Status Consideration: The LSYAC3KQ-FP-C is classified as obsolete, while the LSYAC3KQ-FP maintains active product status. This status difference indicates continued manufacturing and availability of the substitute part, supporting long-term supply chain reliability.

Compliance Alignment: Both parts maintain RoHS compliance and MSL rating 1 (Unlimited), ensuring regulatory and environmental compatibility with existing system requirements.

Packaging Distinction: The primary difference between these components is packaging configuration. The main part (LSYAC3KQ-FP-C) is supplied with unspecified packaging, while the substitute (LSYAC3KQ-FP) is supplied in bulk packaging. This packaging difference does not affect electrical or mechanical performance and does not impact functional substitution.

Inventory Availability: Both parts are currently available in stock, with the substitute part maintaining 908 units of new original inventory.

Frequently Asked Questions (FAQ)

Q: Can LSYAC3KQ-FP replace LSYAC3KQ-FP-C in existing applications?

A: Yes. The LSYAC3KQ-FP is a direct substitute for LSYAC3KQ-FP-C. All electrical parameters (7A AC at 120V, 800mA DC at 115V), mechanical specifications (side rotary actuator, chassis mount, connector termination), and environmental ratings (IP67, -12°C to 121°C operating range) are identical. The components are functionally equivalent.

Q: What is the significance of the product status difference between these parts?

A: The LSYAC3KQ-FP-C is obsolete, meaning it is no longer manufactured. The LSYAC3KQ-FP maintains active status, indicating ongoing production and availability. For new designs or long-term maintenance requirements, the active substitute part provides superior supply chain continuity.

Q: Does the packaging difference affect component performance?

A: No. Packaging is a logistics and handling consideration only. The bulk packaging of LSYAC3KQ-FP does not alter electrical performance, mechanical operation, or environmental compliance compared to the main part.

Q: Are both parts RoHS compliant?

A: Yes. Both LSYAC3KQ-FP-C and LSYAC3KQ-FP are RoHS compliant with MSL rating 1 (Unlimited), meeting regulatory requirements for hazardous substance restrictions.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is based on equivalence across circuit configuration (SPDT DB/DM), current ratings (7A AC / 800mA DC), voltage ratings (120V AC / 115V DC), actuator type (side rotary without lever), mounting type (chassis mount), termination style (connector), ingress protection (IP67), operating temperature range (-12°C to 121°C), and mechanical specifications (operating force 46gfm, pretravel 15°, differential travel 5°, overtravel 60°).

Q: Is the LSYAC3KQ-FP available in the same quantity as the obsolete part?

A: Current inventory shows 908 units of LSYAC3KQ-FP in stock compared to 986 units of LSYAC3KQ-FP-C. Both quantities represent substantial availability for component procurement.
