AM50640C33-A Equivalent & Substitute Parts

Part Overview

The AM50640C33-A is a snap action switch manufactured by Panasonic Electric Works, classified as SPDT (Single Pole Double Throw) with On-Momentary function. This chassis-mounted switch is rated for 6A AC at 125V and features a round pin plunger actuator with quick connect 0.187" termination. The product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and new design applications where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50640C33-A is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Actuator type must be Round (Pin Plunger)
• Mounting type must be Chassis Mount
• Operating position must be 0.579" (14.7mm)

Electrical Compatibility Criteria:

• Current rating must meet or exceed 6A AC
• Voltage rating (AC) must meet or exceed 125V
• Termination style compatibility with 0.187" (4.7mm) quick connect

Environmental Compatibility Criteria:

• Operating temperature range must encompass the application requirements
• Moisture sensitivity level must be acceptable for the intended environment

The three substitute parts listed below satisfy the primary mechanical and functional criteria while offering variations in electrical ratings and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

D433-R1AA-G2 (ZF Electronics) provides the closest electrical match with 6A AC current rating at 250V, maintaining identical termination style (0.187" quick connect) and operating position. This part is active and ROHS3 compliant. The higher voltage rating (250V vs. 125V) provides additional safety margin. Operating temperature range (-40°C to 85°C) is narrower than the original but suitable for most industrial applications.

LS0851500F250C1A (E-Switch) offers the highest current capacity at 15A AC, matching the original 125V AC voltage rating and termination style. This part is active and ROHS3 compliant. The higher current rating provides design flexibility for applications requiring increased electrical capacity. Operating temperature range (-25°C to 85°C) aligns with the original lower bound.

83161806 (Crouzet) meets the SPDT configuration and On-Momentary function with 5A AC current rating at 250V. This part is active and RoHS compliant. The termination style differs (0.250" vs. 0.187"), requiring mechanical adapter consideration. Extended operating temperature range (-60°C to 150°C) suits extreme environment applications. Mechanical life rating (20,000,000 cycles) exceeds the original specification.

All three substitutes maintain MSL 1 (Unlimited) moisture sensitivity and REACH Unaffected status, ensuring compliance consistency with the original part.

Frequently Asked Questions (FAQ)

Q: Can the 83161806 be used as a direct replacement for the AM50640C33-A?

A: The 83161806 satisfies all functional requirements (SPDT, On-Momentary, round pin plunger, chassis mount, 0.579" operating position). However, the termination style differs: 0.250" (6.3mm) versus 0.187" (4.7mm). Direct mechanical substitution requires verification of connector compatibility or use of an appropriate adapter.

Q: Which substitute provides the best electrical compatibility?

A: The D433-R1AA-G2 matches the original 6A AC current rating and maintains identical termination style (0.187" quick connect). The higher voltage rating (250V) provides additional operational margin compared to the original 125V specification.

Q: Is the LS0851500F250C1A suitable for applications requiring higher current capacity?

A: Yes. The LS0851500F250C1A is rated for 15A AC, exceeding the original 6A specification. It maintains the original 125V AC voltage rating and 0.187" termination style. This part is appropriate for designs requiring increased current handling capability within the same voltage class.

Q: What are the temperature operating range considerations for substitution?

A: The original AM50640C33-A operates from -25°C to 105°C. The D433-R1AA-G2 operates from -40°C to 85°C (narrower upper limit), the LS0851500F250C1A from -25°C to 85°C (narrower upper limit), and the 83161806 from -60°C to 150°C (extended range). Selection depends on the specific application temperature requirements.

Q: Are all substitutes RoHS and REACH compliant?

A: All three substitutes maintain MSL 1 (Unlimited) moisture sensitivity and REACH Unaffected status. The D433-R1AA-G2 and LS0851500F250C1A are ROHS3 compliant. The 83161806 is RoHS compliant. All meet current environmental compliance standards.

Q: What is the impact of different operating forces among the substitutes?

A: Operating force varies: original 50gf, 83161806 at 82gf, D433-R1AA-G2 at 173gf, and LS0851500F250C1A at 250gf. Higher operating force requires greater actuator pressure for switch activation. Application-specific actuation requirements must be evaluated during substitution.
