Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSYNC5KQ-FP is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPDT DB/DM), switch function (On-On), current ratings (10A AC / 800mA DC), and voltage ratings (120V AC / 115V DC) must be identical.

Mechanical Parameters: Actuator type (Side Rotary - No Lever), mounting type (Chassis Mount), and termination style (Cable Leads) must match exactly.

Environmental Parameters: Ingress protection rating (IP67), operating temperature range (-1°C to 100°C), and cable length (12') must be maintained.

Compliance Parameters: RoHS compliance status and MSL rating must be equivalent or superior.

The LSYNC3KP-FP meets all substitution criteria and is classified as an active product, providing supply continuity for the obsolete LSYNC5KQ-FP.

Parameter Comparison

Engineering Selection Recommendations

The LSYNC3KP-FP is a direct functional equivalent to the LSYNC5KQ-FP. All electrical, mechanical, and environmental parameters are identical across both components. The primary distinction is product status: the LSYNC5KQ-FP is obsolete while the LSYNC3KP-FP is active and currently in production.

For applications currently using the LSYNC5KQ-FP, the LSYNC3KP-FP provides equivalent performance with assured supply chain continuity. Both components maintain RoHS compliance and identical MSL ratings, ensuring compatibility with existing manufacturing and storage protocols.

The LSYNC3KP-FP is suitable for direct substitution in new designs and field replacement applications where the LSYNC5KQ-FP specifications are required.

Frequently Asked Questions (FAQ)

Q: Can the LSYNC3KP-FP replace the LSYNC5KQ-FP in existing applications?

A: Yes. The LSYNC3KP-FP is electrically and mechanically equivalent to the LSYNC5KQ-FP. All critical parameters including circuit configuration, current and voltage ratings, actuator type, mounting configuration, and environmental protection ratings are identical.

Q: What is the primary reason for substitution?
