AM51142D43N-A Equivalent & Substitute Parts

Part Overview

The AM51142D43N-A is a snap action switch manufactured by Panasonic Electric Works, configured as a single-pole double-throw (SPDT) device with on-momentary switch function. This component is rated for 11A AC at 125V and features a straight lever actuator with chassis mount configuration and quick connect 0.250" (6.3mm) termination. The part is classified as obsolete, making identification of equivalent and substitute components essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51142D43N-A is determined by the following critical parameters: circuit configuration (SPDT), switch function (On-Mom), current and voltage ratings, actuator type (lever, straight), mounting type (chassis mount), and termination style (quick connect 0.250").

The substitute parts identified fall into two categories based on parameter alignment:

Category 1 - Direct Electrical and Mechanical Equivalents: Parts matching the primary electrical specifications (11A AC at 125V), circuit configuration (SPDT), switch function (On-Mom), actuator type (straight lever), mounting type (chassis mount), and termination style (0.250" quick connect). These parts demonstrate compatibility across all critical functional parameters.

Category 2 - Electrical Upgrade with Compatible Mechanical Interface: Parts that exceed the voltage rating (250V AC) while maintaining SPDT configuration, on-momentary function, straight lever actuator, chassis mount, and 0.250" quick connect termination. These parts provide enhanced electrical capability within the same mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

V7-1B17D8-122 (Honeywell Sensing and Productivity Solutions): This part provides direct electrical and mechanical compatibility with the AM51142D43N-A. Both components share identical SPDT circuit configuration, on-momentary switch function, 11A AC at 125V rating, straight lever actuator, chassis mount configuration, and 100,000 cycle electrical life. The V7-1B17D8-122 is currently in active production status with RoHS compliance and REACH unaffected certification. Note that the termination style differs (0.187" versus 0.250" quick connect), requiring connector verification during integration. Operating temperature range is narrower (-40°C to 85°C versus -25°C to 105°C).

V7-1B17D8-122-1 (Honeywell Sensing and Productivity Solutions): This variant is listed as an equivalent substitute in the original part documentation. Product status is active with RoHS compliance. Detailed electrical and mechanical specifications are not fully provided in the available data, limiting comprehensive parameter comparison.

83264022 (Crouzet): This part offers electrical upgrade capability with 12A AC at 250V rating while maintaining SPDT configuration, on-momentary function, straight lever actuator, chassis mount, and 0.250" quick connect termination compatibility. The component is active production status with RoHS compliance and REACH unaffected certification. Mechanical life rating is lower (1,000,000 cycles versus 10,000,000 cycles). Operating temperature range extends to 125°C maximum.

Frequently Asked Questions (FAQ)

Q: Can the V7-1B17D8-122 directly replace the AM51142D43N-A without modification?

A: The V7-1B17D8-122 provides electrical and functional equivalence across circuit configuration, current rating, voltage rating, and switch function. However, the termination style differs: the V7-1B17D8-122 uses 0.187" (4.7mm) quick connect terminals versus the 0.250" (6.3mm) quick connect on the AM51142D43N-A. Connector compatibility must be verified before installation.

Q: What is the primary difference between the Honeywell V7-1B17D8-122 and Crouzet 83264022?

A: The Crouzet 83264022 is rated for higher voltage (250V AC versus 125V AC) and slightly higher current (12A versus 11A). Both maintain SPDT configuration and on-momentary function. The Crouzet part has lower mechanical life (1,000,000 cycles versus 10,000,000 cycles) and uses identical 0.250" quick connect termination. Selection depends on voltage requirements and cycle life expectations for the application.

Q: Are all substitute parts RoHS compliant?

A: Yes. The V7-1B17D8-122, V7-1B17D8-122-1, and 83264022 are all RoHS compliant. The original AM51142D43N-A does not specify RoHS status.

Q: What is the operating temperature consideration when substituting?

A: The AM51142D43N-A operates from -25°C to 105°C. The V7-1B17D8-122 operates from -40°C to 85°C (narrower upper limit). The Crouzet 83264022 operates from -20°C to 125°C (extended upper limit). Application temperature requirements must be verified against each substitute part's range.

Q: Does the V7-1B17D8-122-1 provide complete specification data?

A: The V7-1B17D8-122-1 is documented as an equivalent substitute in the original part reference. However, detailed electrical and mechanical specifications are not fully provided in the available technical data. The part is active production status with RoHS compliance. Complete specification sheets should be obtained from Honeywell for comprehensive evaluation.
