AM51153C43N-A Equivalent & Substitute Parts

Part Overview

The AM51153C43N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a single-pole, single-throw normally closed (SPST-NC) device with a 11A AC / 600mA DC current rating at 125V. This chassis-mounted switch features a straight lever actuator with quick-connect termination and is rated for 100,000 electrical cycles and 10,000,000 mechanical cycles. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51153C43N-A is determined by the following critical parameters:

• Circuit configuration must be SPST-NC
• Switch function must be On-Mom (momentary)
• Actuator type must be lever, straight
• Mounting type must be chassis mount
• Termination style must be quick connect 0.187" (4.7mm)
• Current rating (AC) must be equal to or greater than 11A
• Voltage rating (AC) must be equal to or greater than 125V
• Operating temperature range must encompass or exceed -25°C to 105°C

The identified substitute parts meet these core electrical and mechanical compatibility criteria, enabling direct functional replacement in applications requiring SPST-NC snap-action switching with lever actuation and quick-connect termination.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are classified as active products with current manufacturing support, providing supply chain continuity for the obsolete AM51153C43N-A.

The Crouzet 83264643 offers higher voltage rating (250V AC) and current capacity (12A AC), making it suitable for applications requiring enhanced electrical margins. This part is RoHS Compliant and REACH Unaffected.

The E-Switch LS0851503F025C1B provides the highest current rating (15A AC) and maintains the original 125V AC voltage specification. This part is ROHS3 Compliant and REACH Unaffected. However, the upper operating temperature limit is 85°C, which is lower than the original part's 105°C specification.

Selection should be based on specific application requirements regarding voltage, current, and temperature operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264643 be used in place of the AM51153C43N-A in all applications?

A: The Crouzet part meets all core substitution criteria: SPST-NC circuit, On-Mom function, lever straight actuator, chassis mount, and 0.187" quick-connect termination. The higher voltage rating (250V) and current capacity (12A) provide electrical margin. Compatibility depends on whether the application can accommodate the higher voltage specification and the lower upper operating temperature limit of 125°C versus the original 105°C.

Q: What are the mechanical compatibility considerations?

A: All three parts share identical mounting type (chassis mount) and termination style (quick connect 0.187"). Operating positions are nearly identical (0.602" to 0.606"), ensuring mechanical fit in existing installations. Pretravel and differential travel specifications vary; consult mechanical design requirements for critical applications.

Q: Which substitute part is most suitable for high-temperature applications?

A: The Crouzet 83264643 supports the highest upper operating temperature at 125°C. The E-Switch LS0851503F025C1B is limited to 85°C, which does not meet the original part's 105°C specification. For applications requiring the full -25°C to 105°C range, the Crouzet part is the appropriate selection.

Q: Are there compliance differences between the substitute parts?

A: The Crouzet 83264643 is RoHS Compliant and REACH Unaffected. The E-Switch LS0851503F025C1B is ROHS3 Compliant and REACH Unaffected. Both parts carry EAR99 ECCN classification. Compliance requirements for your specific application should determine part selection.

Q: What is the difference in electrical life between these parts?

A: The original AM51153C43N-A is rated for 100,000 electrical cycles. Both substitute parts are rated for 50,000 cycles (E-Switch) or unspecified (Crouzet). For applications with high cycle count requirements, electrical life specifications should be evaluated against actual usage patterns.
