AM50635C33-A Equivalent & Substitute Parts

Part Overview

The AM50635C33-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device with chassis mount termination. This component is rated for 6A at 125V AC and 500mA at 125V DC, featuring a lever-roller actuator with quick connect 0.187" (4.7mm) termination. The part is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50635C33-A is determined by strict alignment across the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPST-NO
• Switch function must be Off-Mom (momentary operation)
• Actuator type must be Lever, Roller
• Mounting type must be Chassis Mount
• Termination style must be Quick Connect - 0.187" (4.7mm)

Secondary Electrical Criteria:

• Current and voltage ratings must meet or exceed the original specification (6A @ 125V AC minimum)
• Operating temperature range must encompass the original range (-25°C to 105°C minimum)

Tertiary Mechanical Criteria:

• Operating position tolerance must be within 0.815" ± acceptable variance
• Pretravel, differential travel, and overtravel characteristics must be compatible with the original mechanical envelope

Two substitute parts meet these criteria: TMCGD6VA2040Y (C&K) and LS085R105F250C1C (E-Switch). The TMCGD6VA2040Y provides superior electrical performance and extended operating range. The LS085R105F250C1C operates within reduced electrical specifications and is suitable only for applications with lower current and voltage demands.

Engineering Selection Recommendations

TMCGD6VA2040Y (C&K) - Primary Substitute

This part is the preferred substitute for direct replacement applications. It maintains electrical parity with the original specification (10A @ 125V AC exceeds the 6A requirement) and provides extended operating temperature range (-55°C to 150°C). The part is currently in active production status with ROHS3 compliance certification. Electrical life rating of 350,000 cycles exceeds the original 100,000-cycle specification. Mechanical compatibility is confirmed through identical termination style, mounting type, and actuator configuration with negligible operating position variance (0.812" vs. 0.815").

LS085R105F250C1C (E-Switch) - Limited Scope Substitute

This part is suitable only for applications where electrical demands are significantly reduced from the original specification. The 0.4VA rating at 20V AC/DC represents a substantial derating from the original 6A @ 125V specification and is incompatible with circuits designed for the full electrical capacity of the AM50635C33-A. Operating temperature range (-25°C to 85°C) does not encompass the upper limit of the original specification (105°C). Electrical life of 50,000 cycles is half the original rating. This substitute is appropriate only for low-power control circuits or where thermal environment is constrained to below 85°C.

Frequently Asked Questions (FAQ)

Q: Can TMCGD6VA2040Y be used as a direct drop-in replacement for AM50635C33-A?

A: Yes. Both parts share identical circuit configuration (SPST-NO), switch function (Off-Mom), actuator type (Lever, Roller), mounting type (Chassis Mount), and termination style (Quick Connect - 0.187"). Electrical specifications of the C&K part exceed the original requirement. Operating position variance is 0.003" (0.1mm), which is within acceptable mechanical tolerance for chassis-mounted switches.

Q: What are the limitations of using LS085R105F250C1C as a substitute?

A: The E-Switch part operates at significantly reduced electrical capacity (0.4VA @ 20V versus 6A @ 125V). It is not suitable for circuits requiring the full current or voltage rating of the original part. Additionally, the maximum operating temperature of 85°C does not accommodate applications requiring operation at the original specification's upper limit of 105°C.

Q: Are both substitute parts currently available?

A: Yes. TMCGD6VA2040Y (C&K) is in active production with 954 units in stock. LS085R105F250C1C (E-Switch) is in active production with 1,088 units in stock. The original AM50635C33-A is obsolete with 749 units remaining in inventory.

Q: Do the substitute parts have environmental compliance certifications?

A: TMCGD6VA2040Y carries ROHS3 compliance certification. Both substitute parts are REACH Unaffected and classified as EAR99 for export control purposes. Compliance documentation should be verified with the respective manufacturers for specific application requirements.

Q: How do the mechanical life ratings compare?

A: The original AM50635C33-A specifies 10,000,000 mechanical cycles. TMCGD6VA2040Y does not provide a mechanical life specification in the available data. LS085R105F250C1C specifies 1,000,000 mechanical cycles, representing a tenfold reduction from the original specification.

Q: What is the significance of the operating force and release force differences?

A: Operating force (50gf for TMCGD6VA2040Y versus 60gf for the original) and release force (both 10gf) indicate slightly reduced actuation effort for the C&K substitute. LS085R105F250C1C requires substantially higher operating force (250gf) and release force (50gf), which may affect user interface feel and require different mechanical linkage design in applications with force-sensitive actuation requirements.
