AM50012C33-A Equivalent & Substitute Parts

Part Overview

The AM50012C33-A is a snap-action SPDT switch manufactured by Panasonic Electric Works, designed for chassis mount applications with quick connect termination. This component operates at 125V AC and 30V DC with a 100mA current rating. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50012C33-A is determined by the following critical parameters: SPDT circuit configuration, on-momentary switch function, chassis mount design, and quick connect 0.187" termination. All substitute parts must maintain these core mechanical and electrical interface requirements.

The three identified substitute parts are grouped based on their compatibility with these parameters:

Group 1 - Direct Voltage/Current Match: D413-R1LD-G2 maintains the 125V AC rating and 100mA AC current specification, with enhanced 250V AC capability and 500mA DC rating, providing expanded operational flexibility.

Group 2 - Enhanced Current Capacity: LS0851502F120C1A and TFS10ST2040C both provide significantly higher current ratings (15A and 10A respectively) while maintaining 125V AC compatibility, suitable for applications requiring increased power handling.

All substitute parts preserve the SPDT configuration, on-momentary function, lever straight actuator, chassis mount design, and quick connect termination required for mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

D413-R1LD-G2 (ZF Electronics): This substitute provides the closest electrical match to the AM50012C33-A with 100mA AC current and 125V AC voltage compatibility. The part is ROHS3 compliant and active in production. The expanded 250V AC and 500mA DC ratings offer operational margin. Operating temperature range is reduced to -40°C to 85°C, which may require verification for applications requiring the original -25°C to 105°C range. Electrical life is reduced to 50,000 cycles.

LS0851502F120C1A (E-Switch): This substitute is suitable for applications where increased current capacity (15A AC) is beneficial while maintaining 125V AC compatibility. The part is ROHS3 compliant, REACH unaffected, and active in production. Operating temperature range is -25°C to 85°C. Electrical life is 50,000 cycles with mechanical life of 1,000,000 cycles. This option is appropriate for designs requiring higher current handling than the original 100mA specification.

TFS10ST2040C (C&K): This substitute provides 10A AC current capacity at 125V AC with ROHS3 compliance and active production status. The part includes IP40 ingress protection and operates across -40°C to 85°C. Mechanical life matches the original at 10,000,000 cycles. This option is suitable for applications requiring enhanced current capacity with environmental protection.

Frequently Asked Questions (FAQ)

Q: Can D413-R1LD-G2 be used as a direct replacement for AM50012C33-A?

A: D413-R1LD-G2 maintains electrical and mechanical compatibility through matching SPDT configuration, on-momentary function, 100mA AC current, 125V AC voltage, lever straight actuator, chassis mount design, and quick connect 0.187" termination. However, the operating temperature range is reduced from -25°C to 105°C to -40°C to 85°C, and electrical life is reduced from 100,000 to 50,000 cycles. Verify these parameters against application requirements before selection.

Q: What is the primary difference between the three substitute options?

A: D413-R1LD-G2 matches the original 100mA current rating with enhanced voltage capability. LS0851502F120C1A and TFS10ST2040C provide significantly higher current ratings (15A and 10A respectively) for applications requiring increased power handling. All three maintain the required SPDT configuration, on-momentary function, and quick connect termination.

Q: Are all substitute parts RoHS compliant?

A: Yes, all three substitute parts (D413-R1LD-G2, LS0851502F120C1A, and TFS10ST2040C) are ROHS3 compliant. The original AM50012C33-A does not specify RoHS status.

Q: What packaging options are available for these substitutes?

A: D413-R1LD-G2 is supplied in bulk packaging. LS0851502F120C1A is supplied in bulk packaging. TFS10ST2040C is supplied in box packaging. Verify packaging requirements for procurement and handling procedures.

Q: Do all substitutes support the original operating temperature range?

A: No. The original AM50012C33-A operates from -25°C to 105°C. D413-R1LD-G2 and TFS10ST2040C operate from -40°C to 85°C, providing lower temperature capability but reduced upper temperature limit. LS0851502F120C1A operates from -25°C to 85°C, matching the lower temperature but reducing the upper limit. Confirm application temperature requirements before selection.

Q: What is the mechanical life comparison?

A: The original AM50012C33-A specifies 10,000,000 mechanical cycles. D413-R1LD-G2 does not specify mechanical life. LS0851502F120C1A specifies 1,000,000 cycles. TFS10ST2040C specifies 10,000,000 cycles, matching the original. For applications with high cycle count requirements, TFS10ST2040C provides equivalent mechanical durability.
