AM50036C43-A Equivalent & Substitute Parts

Part Overview

The AM50036C43-A is a SPST-NO (Single Pole Single Throw - Normally Open) snap-action switch manufactured by Panasonic Electric Works. This chassis-mounted switch is rated for 100mA at 125V AC and 30V DC, featuring a lever roller actuator with quick connect termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications where continued component availability is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50036C43-A requires matching the following critical parameters:

Mandatory Compatibility Criteria:

• Circuit configuration: SPST-NO topology
• Switch function: Off-Mom (momentary action)
• Termination style: Quick Connect - 0.187" (4.7mm) connector
• Current and voltage ratings: Must meet or exceed 100mA at 125V AC minimum

Mechanical Considerations:

• Actuator type compatibility with lever/roller operation
• Operating position and travel characteristics within acceptable tolerance ranges
• Temperature operating range encompassing the original -25°C to 105°C specification

The Crouzet 831615A6.L qualifies as a functional substitute based on matching SPST-NO circuit topology, momentary operation, identical quick connect termination, and superior electrical ratings (4A at 250V AC). While mounting type differs (panel mount versus chassis mount), the electrical and mechanical switching characteristics align with substitution requirements.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 831615A6.L presents a viable substitute for the obsolete AM50036C43-A based on the following engineering factors:

Electrical Compatibility: The Crouzet part exceeds the original current and voltage specifications (4A at 250V AC versus 100mA at 125V AC), providing margin for application requirements. Both parts share identical SPST-NO circuit topology and momentary operation.

Termination Compatibility: Both parts utilize Quick Connect - 0.187" (4.7mm) termination, ensuring direct connector compatibility without adapter requirements.

Mechanical Considerations: Operating positions are within 0.031" (0.8mm) of each other, and both parts maintain momentary switching function. The Crouzet part offers extended mechanical life (50,000,000 cycles versus 10,000,000 cycles) and broader operating temperature range (-20°C to 125°C versus -25°C to 105°C).

Product Status: The Crouzet 831615A6.L is active production status with current inventory availability (1100 pcs), whereas the AM50036C43-A is obsolete. RoHS compliance and REACH unaffected status of the Crouzet part align with modern regulatory requirements.

Mounting Consideration: The primary design difference is mounting type (panel mount versus chassis mount). System integration must accommodate this mechanical interface change through appropriate mounting bracket or enclosure modification.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 831615A6.L directly replace the AM50036C43-A without circuit modification?

A: Electrical substitution is direct due to matching SPST-NO topology, identical termination style, and superior ratings. Mechanical mounting requires adaptation from chassis mount to panel mount configuration.

Q: Are the quick connect terminals fully compatible between these parts?

A: Both parts use Quick Connect - 0.187" (4.7mm) termination, enabling direct connector compatibility without terminal adapter requirements.

Q: What is the impact of the different actuator types (lever/roller versus telescopic plunger)?

A: Actuator type affects mechanical interface and actuation feel but does not impact electrical switching characteristics. System design must accommodate the telescopic plunger actuation profile of the Crouzet part.

Q: Does the Crouzet part meet the original temperature operating range?

A: The Crouzet part operates from -20°C to 125°C, which encompasses the original -25°C to 105°C range except for the lower -25°C limit. Application requirements below -20°C would require alternative evaluation.

Q: Is the Crouzet 831615A6.L RoHS compliant?

A: Yes, the Crouzet 831615A6.L is RoHS compliant and REACH unaffected, meeting current regulatory standards.

Q: What is the significance of the 40x higher mechanical life rating of the Crouzet part?

A: The Crouzet part (50,000,000 cycles) provides extended service life compared to the original (10,000,000 cycles), reducing replacement frequency in high-cycle applications.
