Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSXA3K-5C is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Circuit configuration: SPDT (DB/DM)
• Switch function: On-Mom
• Current rating: 10A AC minimum, 800mA DC minimum
• Voltage rating: 120V AC minimum, 115V DC minimum

Mechanical Equivalence Requirements:

• Actuator type: Side Rotary, Roller
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Operating force: 46gfm
• Pretravel: 15°
• Differential travel: 5°
• Overtravel: 60°

Environmental & Compliance Requirements:

• Operating temperature range: -12°C to 121°C
• RoHS compliance status
• MSL rating: 1 (Unlimited)

The LSA3K-1A meets all specified electrical, mechanical, and environmental parameters and qualifies as a direct substitute for the obsolete LSXA3K-5C.

Engineering Selection Recommendations

The LSA3K-1A is a direct functional and mechanical equivalent to the obsolete LSXA3K-5C. Selection of the LSA3K-1A as a substitute is supported by the following factors:

Product Status Alignment: The LSXA3K-5C is classified as obsolete, creating supply constraints. The LSA3K-1A maintains active product status with documented inventory availability (957 Pcs New Original In Stock), ensuring procurement feasibility for current and future production requirements.

Compliance Certification: Both components maintain identical RoHS compliance status and MSL rating of 1 (Unlimited), confirming equivalent environmental and regulatory standing for applications subject to these standards.

Electrical and Mechanical Specification Parity: All critical electrical parameters (current and voltage ratings), mechanical specifications (actuator type, mounting configuration, operating force, travel angles), and environmental operating range are identical between the two components. This parity eliminates the need for circuit redesign or mechanical rework.

Termination and Interface Compatibility: Both components utilize screw terminal termination and chassis mount configuration, ensuring direct compatibility with existing PCB layouts and mechanical assemblies designed for the LSXA3K-5C.

Frequently Asked Questions (FAQ)

Q: Can the LSA3K-1A be used as a direct replacement for the LSXA3K-5C without circuit modification?

A: Yes. The LSA3K-1A is electrically and mechanically equivalent to the LSXA3K-5C across all specified parameters. No circuit modification is required. The identical current ratings (10A AC, 800mA DC), voltage ratings (120V AC, 115V DC), circuit configuration (SPDT), and switch function (On-Mom) ensure direct functional compatibility.

Q: What is the primary reason for substituting the LSXA3K-5C?

A: The LSXA3K-5C is classified as obsolete product status, which creates supply chain risk and procurement difficulty. The LSA3K-1A is an active product with confirmed inventory availability, providing supply continuity and long-term availability assurance.

Q: Are there mechanical installation differences between the LSXA3K-5C and LSA3K-1A?

A: No. Both components share identical mounting specifications: chassis mount configuration, side rotary roller actuator type, screw terminal termination, and identical operating force (46gfm). Mechanical installation is identical.

Q: Do both components meet the same environmental and compliance standards?

A: Yes. Both the LSXA3K-5C and LSA3K-1A are RoHS compliant and carry MSL rating 1 (Unlimited). Both operate across the identical temperature range of -12°C to 121°C, confirming equivalent environmental qualification.

Q: What is the difference in packaging between these two components?

A: The LSXA3K-5C is supplied with standard packaging (indicated as "-" in specifications). The LSA3K-1A is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance and should be selected based on procurement and inventory management requirements.

Q: Are the travel specifications identical?

A: Yes. Both components have identical pretravel (15°), differential travel (5°), and overtravel (60°) specifications, confirming mechanical behavior equivalence.
