AM50040C43-A Equivalent & Substitute Parts

Part Overview

The AM50040C43-A is a snap-action switch manufactured by Panasonic Electric Works, featuring SPDT (Single Pole Double Throw) circuit configuration with momentary operation. This component is rated for 0.1A at 125V AC and 30V DC, with chassis mount installation and quick connect termination. The product is currently obsolete, making identification of equivalent substitute parts essential for system maintenance, repair, and redesign applications where this switch is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AM50040C43-A are identified based on the following core compatibility parameters:

• Circuit Configuration: SPDT topology required for functional equivalence
• Switch Function: On-Momentary operation maintained across substitutes
• Actuator Type: Round pin plunger design for mechanical compatibility
• Mounting Type: Chassis mount configuration
• Termination Style: Quick connect terminals for installation compatibility
• Operating Position: 0.579" (14.7mm) travel distance maintained

The identified substitutes meet these core mechanical and electrical interface requirements. Voltage and current ratings vary among substitutes; selection depends on the specific application voltage and current demands within the target system.

Parameter Comparison

Engineering Selection Recommendations

LS0851500F250C1A (E-Switch) is the primary substitute for direct replacement applications. This part maintains identical AC voltage rating (125V), matching termination style (0.187" quick connect), and equivalent operating position. The higher current rating (15A) and RoHS3 compliance provide enhanced capability for modern applications. Product status is active with current inventory availability.

83161806 (Crouzet) serves as an alternative for applications requiring higher voltage operation (250V AC) or extended temperature range (-60°C to 150°C). This substitute features higher current capacity (5A AC) and superior mechanical life (20,000,000 cycles). Termination style differs (0.250" quick connect), requiring connector adaptation. RoHS compliance and REACH unaffected status support regulatory requirements. Product status is active.

Both substitutes maintain SPDT circuit configuration, on-momentary function, round pin plunger actuator, and chassis mount design. Selection between substitutes depends on specific voltage, current, temperature, and termination requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can LS0851500F250C1A directly replace AM50040C43-A without modification?

A: LS0851500F250C1A maintains identical AC voltage rating (125V), matching termination style (0.187" quick connect), and equivalent operating position (0.579"). Direct mechanical and electrical interface compatibility is established. The higher current rating (15A versus 100mA) does not prevent substitution in applications requiring lower current.

Q: What is the primary difference between the two substitute options?

A: LS0851500F250C1A matches the original 125V AC rating and 0.187" termination, making it suitable for direct replacement. 83161806 operates at 250V AC with 0.250" termination, requiring connector modification but offering extended temperature range and higher current capacity.

Q: Are both substitutes RoHS compliant?

A: LS0851500F250C1A carries RoHS3 compliance. 83161806 is RoHS compliant. Both meet current regulatory requirements for electronic component manufacturing and distribution.

Q: What connector modification is required if using 83161806?

A: 83161806 uses 0.250" (6.3mm) quick connect terminals versus the original 0.187" (4.7mm) specification. Connector adapters or harness modification is necessary for installation.

Q: Which substitute offers the longest mechanical life?

A: 83161806 provides 20,000,000 mechanical cycles, compared to 10,000,000 cycles for the original AM50040C43-A and 1,000,000 cycles for LS0851500F250C1A.

Q: Can these substitutes be used in DC applications?

A: LS0851500F250C1A and 83161806 specifications do not include DC voltage ratings. The original AM50040C43-A is rated for 30V DC. Applications requiring DC operation should confirm compatibility with the substitute manufacturer's technical documentation.
