Engineering Selection Recommendations
D413-R1LD-G2 (ZF Electronics) is suitable for applications requiring enhanced AC voltage tolerance (250V) and higher DC current capacity (500mA). This part is ROHS3 compliant and active in production. The higher operating force (88gf) and release force (20gf) may affect actuation feel compared to the original. Operating temperature range is reduced to -40°C to 85°C.
LS0851502F120C1A (E-Switch) is appropriate for high-current AC applications requiring 15A switching capability. This part is ROHS3 compliant and active in production. The significantly higher operating force (120gf) and release force (40gf) represent a substantial change in actuation characteristics. Mechanical life is reduced to 1,000,000 cycles.
TFS10ST2040C (C&K) is suitable for applications requiring 10A AC switching with IP40 ingress protection. This part is ROHS3 compliant and active in production. Operating force (90gf) and release force (10gf) are closer to the original specification. Mechanical life matches the original at 10,000,000 cycles. Operating temperature range extends to -40°C.
All three substitutes are currently active products with modern compliance certifications, addressing the obsolescence of the original AM50012C43-A.
Frequently Asked Questions (FAQ)
Q: Can D413-R1LD-G2 be used in place of AM50012C43-A in all applications?
A: D413-R1LD-G2 meets the core electrical and mechanical compatibility requirements (SPDT, on-momentary, 125V AC minimum, 100mA minimum, straight lever, chassis mount, 0.187" quick connect). However, the higher operating force (88gf vs. 60gf) and reduced upper operating temperature limit (-40°C to 85°C vs. -25°C to 105°C) must be evaluated against specific application requirements.
Q: What is the primary difference between LS0851502F120C1A and the original AM50012C43-A?
A: LS0851502F120C1A is designed for significantly higher AC current applications (15A vs. 100mA). While it maintains SPDT configuration and on-momentary function, the operating force is substantially higher (120gf vs. 60gf), which affects actuation characteristics. This part is suitable only for applications where the higher current rating is required or acceptable.
Q: Is TFS10ST2040C a direct replacement for AM50012C43-A?
A: TFS10ST2040C maintains compatibility across all primary parameters: SPDT circuit, on-momentary function, straight lever actuator, chassis mount, and 0.187" quick connect termination. The 10A AC current rating exceeds the original 100mA requirement. Operating force (90gf) is moderately higher than the original (60gf). Mechanical life and release force characteristics are comparable.
Q: Are all substitute parts RoHS compliant?
A: Yes. D413-R1LD-G2, LS0851502F120C1A, and TFS10ST2040C are all ROHS3 compliant, meeting current environmental and regulatory standards.
Q: What packaging formats 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. Packaging selection should align with inventory management and procurement requirements.
Q: How do operating temperature ranges compare?
A: The original AM50012C43-A operates from -25°C to 105°C. D413-R1LD-G2 and TFS10ST2040C both operate from -40°C to 85°C, providing lower temperature capability but reduced upper temperature limit. LS0851502F120C1A operates from -25°C to 85°C. Application temperature requirements must be verified against the selected substitute.
