Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 34ASP11B1M2RT are categorized based on strict electrical and mechanical compatibility criteria. The primary substitution logic follows these parameters:

Group 1 - Direct Electrical Equivalents (0.4VA @ 20V): Parts maintaining identical current rating (0.4VA AC/DC) and voltage rating (20V AC/DC) with matching SPDT circuit configuration and panel-mount specifications. These parts share the same electrical load capacity and voltage withstand characteristics.

Group 2 - Enhanced Electrical Capability (5A @ 120V AC / 28V DC): Parts with higher current ratings (5A) and elevated voltage ratings (120V AC / 28V DC) that provide superior electrical performance margins. These components are electrically compatible in applications where the 34ASP11B1M2RT operates, as they exceed the original specifications.

Key Substitution Parameters:

• Circuit configuration: SPDT (mandatory match)
• Switch function: On-On (mandatory match)
• Mounting type: Panel Mount (mandatory match)
• Panel cutout dimensions: Circular 6.35mm Dia (mandatory match)
• Bushing thread: 1/4-40 (mandatory match)
• Termination style: PC Pin (mandatory match)
• Operating temperature range: -30°C ~ 85°C (mandatory match)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Specifications):

The E-Switch 100SP1T1B1M2REH provides direct electrical equivalence to the 34ASP11B1M2RT with matching 0.4VA @ 20V ratings and identical actuator length (10.41mm). Both components are ROHS3 compliant and maintain the same operating temperature range. The E-Switch variant includes epoxy sealed terminals as an additional feature. This part is suitable for applications requiring no electrical performance changes.

The C&K 7101SDCBE operates at identical electrical specifications (0.4VA @ 20V) with SPDT configuration and panel-mount compatibility. The actuator length differs at 12.45mm versus 10.41mm on the original part. Electrical life extends to 100,000 cycles compared to 40,000 cycles on the Grayhill component. This part is applicable where extended operational life is beneficial and panel space accommodates the longer actuator.

For Enhanced Electrical Performance:

The C&K 7101SDCQE, 7101SDCGE, 7101P3DCQE, 7101P3YCQE, 7101SYCQE, and U11SYCQE all provide 5A @ 120V AC / 28V DC ratings with 100,000-cycle electrical life. These components maintain SPDT circuit configuration, panel-mount specifications, and PC pin termination. All are ROHS3 compliant. Selection among these enhanced-capability parts depends on actuator type preference (standard round versus flat anti-rotation) and packaging requirements (bulk versus tray). These parts are suitable for applications where the original 34ASP11B1M2RT operates within a higher-capacity electrical environment.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance. The C&K components (7101 series and U11SYCQE) carry REACH Affected status, whereas the original Grayhill part and E-Switch component are REACH Unaffected. This distinction applies to applications subject to REACH regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T1B1M2REH directly replace the Grayhill 34ASP11B1M2RT?

A: Yes. Both parts maintain identical electrical ratings (0.4VA @ 20V AC/DC), SPDT circuit configuration, actuator length (10.41mm), and operating temperature range (-30°C to 85°C). Panel cutout dimensions, bushing thread, and termination style are identical. The E-Switch variant includes epoxy sealed terminals. Both are ROHS3 compliant.

Q: What is the difference between the 0.4VA and 5A rated substitute parts?

A: The 0.4VA parts (100SP1T1B1M2REH and 7101SDCBE) match the original electrical load capacity. The 5A parts (7101SDCQE, 7101SDCGE, 7101P3DCQE, 7101P3YCQE, 7101SYCQE, U11SYCQE) provide higher current-handling capability and elevated voltage ratings (120V AC / 28V DC). The 5A parts are electrically compatible in applications where the 34ASP11B1M2RT operates, as they exceed the original specifications.

Q: Does actuator length affect substitution compatibility?

A: Actuator length affects panel space requirements and user interface ergonomics but does not affect electrical compatibility. The original 34ASP11B1M2RT has a 10.41mm actuator. The 7101SDCBE has 12.45mm, the 7101P3DCQE has 13.21mm, and the 7101P3YCQE, 7101SYCQE, and U11SYCQE have 10.67mm or 11.43mm. Verify available panel space before selection.

Q: Are there packaging differences among substitute parts?

A: Yes. The 34ASP11B1M2RT, 100SP1T1B1M2REH, 7101SDCBE, 7101SDCQE, 7101P3YCQE, 7101SYCQE, and U11SYCQE are supplied in bulk packaging. The 7101SDCGE and 7101P3DCQE are supplied in tray packaging. Packaging selection depends on procurement and assembly process requirements.

Q: What is the significance of REACH Affected versus REACH Unaffected status?

A: REACH Unaffected parts (34ASP11B1M2RT and 100SP1T1B1M2REH) are not subject to REACH regulatory restrictions. REACH Affected parts (C&K 7101 series and U11SYCQE) are subject to REACH compliance requirements. Selection depends on application regulatory jurisdiction and supply chain requirements.

Q: Do all substitute parts support the same operating temperature range?

A: Yes. All listed substitute parts operate across -30°C to 85°C, matching the original 34ASP11B1M2RT specification.

Q: What is the difference in electrical life between parts?

A: The original 34ASP11B1M2RT and E-Switch 100SP1T1B1M2REH are rated for 40,000 cycles. All C&K substitute parts (7101 series and U11SYCQE) are rated for 100,000 cycles, providing extended operational life in high-cycle applications.
