Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51640C53N-A is determined by the following critical parameters:

• Circuit configuration must be SPDT
• Switch function must be On-Mom
• Actuator type must be Round (Pin Plunger)
• Mounting type must be Chassis Mount
• Termination style must be Quick Connect - 0.187" (4.7mm)
• Operating position must be 0.579" (14.7mm)
• Current rating must support minimum 16A AC
• Voltage rating must support minimum 125V AC

Based on these criteria, the following parts qualify as substitutes:

Tier 1 - Full Parameter Match:

• Crouzet 83261041: Matches all critical mechanical and electrical parameters with higher voltage rating (250V AC) and equivalent current rating (16A AC)

Tier 2 - Partial Parameter Match:

• Crouzet 83161806: Matches mechanical parameters and circuit configuration but has reduced current rating (5A AC) and elevated voltage rating (250V AC)

Parameter Comparison

Engineering Selection Recommendations

Crouzet 83261041 is the primary substitute for AM51640C53N-A applications. This part maintains active product status, is RoHS compliant, and provides equivalent current handling (16A AC) with enhanced voltage rating (250V AC). The mechanical parameters—operating position, actuator type, mounting configuration, and termination style—are identical to the original component. Operating force and release force values are within 2% of the original specification. The reduced mechanical life rating (1,000,000 cycles versus 10,000,000 cycles) must be evaluated against application duty cycle requirements.

Crouzet 83161806 is a secondary substitute suitable only for applications where current requirements do not exceed 5A AC. This part offers extended mechanical life (20,000,000 cycles) and broader operating temperature range (-60°C to 150°C). The termination style differs (0.250" versus 0.187"), requiring connector compatibility verification. RoHS compliance and active product status support long-term availability.

Both substitute parts share the same ECCN (EAR99) and HTSUS classification as the original component.

Frequently Asked Questions (FAQ)

Q: Can Crouzet 83261041 directly replace AM51640C53N-A in all applications?

A: Crouzet 83261041 is mechanically and electrically compatible for applications operating at or below 16A AC and 125V AC. The identical operating position (0.579"), actuator type (round pin plunger), mounting type (chassis mount), and termination style (0.187" quick connect) ensure physical and functional interchangeability. The higher voltage rating (250V AC) provides additional design margin.

Q: What is the impact of the reduced mechanical life in Crouzet 83261041?

A: Crouzet 83261041 specifies 1,000,000 mechanical cycles compared to 10,000,000 cycles for AM51640C53N-A. This difference is relevant only for high-cycle applications. Applications with moderate switching frequency will not be affected. Duty cycle analysis is required to determine suitability.

Q: Why does Crouzet 83161806 have a different termination style?

A: Crouzet 83161806 uses 0.250" (6.3mm) quick connect terminals versus the 0.187" (4.7mm) standard on AM51640C53N-A. This requires connector compatibility verification and may necessitate harness modification. This part is suitable only when current requirements do not exceed 5A AC.

Q: Are both Crouzet substitutes RoHS compliant?

A: Yes. Both Crouzet 83261041 and 83161806 are RoHS compliant and REACH unaffected, supporting compliance requirements for modern applications.

Q: What is the temperature operating range difference?

A: AM51640C53N-A operates from -25°C to 105°C. Crouzet 83261041 extends this to -20°C to 125°C. Crouzet 83161806 provides the broadest range: -60°C to 150°C. Selection depends on application thermal requirements.
