AM50065C43-A Equivalent & Substitute Parts

Part Overview

The AM50065C43-A is a SPST-NO (Single Pole Single Throw - Normally Open) snap-action switch manufactured by Panasonic Electric Works. This chassis-mount 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 suitable equivalent and substitute parts essential for design continuity and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50065C43-A is determined by the following critical parameters:

• Circuit configuration must remain SPST-NO
• Switch function must be Off-Momentary
• Actuator type must be Lever with Roller
• Mounting type must be Chassis Mount
• Termination style must include Quick Connect - 0.187" (4.7mm)
• Operating position must be 0.815" (20.7mm)

The substitute parts identified maintain these core mechanical and electrical interface requirements. However, variations exist in current and voltage ratings, operating force, temperature range, and cycle life. These variations determine the applicability of each substitute within specific circuit designs and environmental conditions.

Engineering Selection Recommendations

ABV1236619 is an active product from Panasonic Electric Works with RoHS compliance. This substitute provides higher current capacity (3A AC) and voltage rating (250V AC), making it suitable for applications requiring greater electrical headroom than the original AM50065C43-A. The operating force is higher at 180gf, and the mechanical life is reduced to 5,000,000 cycles. Temperature range is extended to -40°C, providing broader environmental coverage.

LS085R105F250C1C is an active product from E-Switch with ROHS3 compliance and REACH unaffected status. This substitute operates at significantly lower voltage (20V AC/DC) and current (0.4VA), with higher operating force (250gf) and substantially reduced cycle life (50,000 electrical cycles, 1,000,000 mechanical cycles). This part is applicable only to low-voltage, low-current applications.

Both substitutes maintain the critical mechanical interface parameters: chassis mount configuration, lever roller actuator, 0.815" operating position, and quick connect 0.187" termination. Selection between substitutes depends on the specific electrical requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can ABV1236619 directly replace AM50065C43-A in all applications?

A: ABV1236619 maintains identical mechanical interface and circuit configuration. However, the higher operating force (180gf vs. 110gf) and reduced mechanical life (5,000,000 vs. 10,000,000 cycles) must be evaluated against application requirements. The higher voltage and current ratings provide compatibility with a broader range of circuits.

Q: What are the voltage and current limitations when using LS085R105F250C1C?

A: LS085R105F250C1C is rated for 20V AC/DC and 0.4VA. This substitute is restricted to low-voltage applications and cannot be used in circuits designed for the original 125V AC or 30V DC ratings.

Q: Are all three parts compatible with the same mounting footprint?

A: Yes. All three parts share identical chassis mount configuration, lever roller actuator type, 0.815" operating position, and quick connect 0.187" termination style. Mechanical installation compatibility is maintained across all substitutes.

Q: What compliance certifications apply to the substitute parts?

A: ABV1236619 carries RoHS compliance. LS085R105F250C1C carries ROHS3 compliance and is REACH unaffected. Both active products meet current regulatory requirements.

Q: How do cycle life differences affect part selection?

A: AM50065C43-A provides 100,000 electrical cycles and 10,000,000 mechanical cycles. ABV1236619 provides 100,000 electrical cycles but only 5,000,000 mechanical cycles. LS085R105F250C1C provides only 50,000 electrical cycles and 1,000,000 mechanical cycles. Applications requiring high cycle counts should prioritize ABV1236619 over LS085R105F250C1C.

Q: Can termination style differences affect installation?

A: ABV1236619 offers both solder and quick connect termination options, providing installation flexibility. AM50065C43-A and LS085R105F250C1C are limited to quick connect 0.187" termination. Existing quick connect installations are compatible with all three parts.
