AM51115C43N-A Equivalent & Substitute Parts

Part Overview

The AM51115C43N-A is a snap action SPDT switch manufactured by Panasonic Electric Works, designed for chassis mount applications with quick connect termination. This component operates at 11A AC (600mA DC) and 125V, featuring a lever roller actuator with on-momentary switching function. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing maintenance, repair, and legacy system support.

Substitute Part Grouping Explanation

Substitution for the AM51115C43N-A is determined by the following critical parameters: circuit configuration (SPDT), switch function (On-Mom), actuator type (Lever, Roller), mounting type (Chassis Mount), and termination style (Quick Connect - 0.187"). The substitute parts must maintain compatibility with these core mechanical and electrical interface requirements.

Two substitute parts are identified based on these criteria:

Crouzet 83264047: Maintains SPDT circuit, On-Mom function, lever roller actuator, and chassis mount configuration. Termination style matches at 0.187" quick connect. Voltage rating increases to 250V AC with 12A current capacity, providing enhanced electrical performance margins.

E-Switch LS0851505F160C2A: Maintains SPDT circuit, On-Mom function, lever roller actuator, and chassis mount configuration. Termination style is 0.250" quick connect, representing a minor mechanical interface difference. Current rating increases to 15A AC at 125V, matching the original voltage specification.

E-Switch LS085R105F160C1A: Maintains SPDT circuit, On-Mom function, lever roller actuator, and chassis mount configuration. Termination style matches at 0.187" quick connect. Operates at reduced voltage (20V AC/DC) and current (0.4VA), suitable for low-voltage applications only.

Parameter Comparison

Engineering Selection Recommendations

Crouzet 83264047 is recommended for applications requiring higher voltage tolerance (250V AC) while maintaining the original 125V operating point. This part is RoHS Compliant and REACH Unaffected, meeting modern regulatory requirements. The increased current rating (12A) provides operational margin above the original 11A specification.

E-Switch LS0851505F160C2A is recommended for direct replacement in 125V AC applications requiring higher current capacity (15A). This part is ROHS3 Compliant and REACH Unaffected. The 0.250" termination requires connector verification for compatibility with existing quick connect receptacles.

E-Switch LS085R105F160C1A is suitable only for low-voltage applications operating at 20V AC/DC with minimal current draw (0.4VA). This part is ROHS3 Compliant and REACH Unaffected. Use is restricted to circuits designed for low-voltage operation and cannot replace the original part in standard 125V applications.

All substitute parts maintain active product status, ensuring availability and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264047 directly replace the AM51115C43N-A in a 125V circuit?

A: Yes. The Crouzet 83264047 operates at 125V and maintains all critical mechanical parameters (SPDT circuit, On-Mom function, lever roller actuator, chassis mount, 0.187" quick connect termination). The 250V rating indicates maximum voltage capability and does not prevent operation at 125V.

Q: What is the primary difference between the E-Switch LS0851505F160C2A and the original part?

A: The termination style differs: LS0851505F160C2A uses 0.250" quick connect versus the original 0.187". Connector compatibility must be verified before installation. Current rating increases from 11A to 15A at the same 125V specification.

Q: Is the E-Switch LS085R105F160C1A suitable for standard 125V applications?

A: No. The LS085R105F160C1A operates at maximum 20V AC/DC and is designed for low-voltage circuits only. It cannot be used in 125V applications.

Q: Do all substitute parts maintain the same mechanical life as the original?

A: No. The original AM51115C43N-A specifies 10,000,000 mechanical cycles. Both E-Switch substitutes specify 1,000,000 cycles. The Crouzet 83264047 also specifies 1,000,000 cycles. Applications requiring extended mechanical life should account for this reduction.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. Crouzet 83264047 is RoHS Compliant and REACH Unaffected. Both E-Switch parts (LS0851505F160C2A and LS085R105F160C1A) are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards.

Q: What is the electrical life difference between the original and substitutes?

A: The original AM51115C43N-A specifies 100,000 electrical cycles. The Crouzet 83264047 does not specify electrical life. Both E-Switch parts specify 50,000 cycles, representing a 50% reduction from the original specification.
