Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

• Circuit configuration (SPDT required)
• Switch function (On-On operation)
• Mounting type (Panel Mount)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread (1/4-40)
• Operating temperature range (-30°C to 85°C minimum)
• Current and voltage ratings (must meet or exceed 0.4VA at 20V AC/DC)

Substitute parts are grouped into two categories:

Direct Equivalent (Same Electrical Rating): Parts with identical or superior current/voltage ratings at the same specification level, maintaining full functional compatibility without circuit redesign.

Functional Equivalent (Higher Electrical Rating): Parts with elevated current or voltage ratings that operate within the same mechanical envelope and mounting interface, suitable for applications where the original specification is met or exceeded.

Parameter Comparison

Engineering Selection Recommendations

Recommended Direct Equivalent:

7101SHCPE (C&K) is the primary direct replacement for the obsolete 7101SHCKE. Both parts share identical electrical ratings (0.4VA at 20V AC/DC), mechanical dimensions, and mounting interface. The 7101SHCPE is currently in active production status and maintains ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Alternative Direct Equivalents:

34ASP11B1M2RT (Grayhill Inc.) and 100AWSP1T1B1M2REH (E-Switch) provide direct electrical and mechanical compatibility. Both maintain the 0.4VA at 20V specification, identical panel cutout dimensions, and 1/4-40 bushing thread. These parts are active production items with ROHS3 compliance. The Grayhill part offers extended electrical life (40,000 cycles vs. 30,000 for E-Switch).

34BWSP11B1M2RT (Grayhill Inc.) provides equivalent electrical performance with IP67 ingress protection (dust tight, waterproof) and extended electrical life (50,000 cycles), suitable for applications requiring enhanced environmental sealing.

Higher-Rated Functional Equivalents:

A123S1CWCB (Electroswitch) operates at 0.5VA at 28V, exceeding the original specification. This part is suitable for applications where the 7101SHCKE specification is met or exceeded, with extended electrical life (60,000 cycles) and improved temperature range (-30°C to 90°C).

M2012ES1W03/UC (NKK Switches) is rated for 6A at 125V AC and 4A at 30V DC, representing a significant electrical upgrade. This part is obsolete but available in inventory. Use is limited to applications where higher electrical ratings are required and the mechanical envelope is acceptable.

Compliance Considerations:

All recommended active production parts maintain ROHS3 or RoHS compliance. The 7101SHCPE is preferred for new designs due to active production status and regulatory continuity.

Frequently Asked Questions (FAQ)

Q: Can I use 7101SHCPE as a direct replacement for 7101SHCKE?

A: Yes. The 7101SHCPE is a direct equivalent with identical electrical ratings (0.4VA at 20V AC/DC), mechanical dimensions, and mounting interface. The primary difference is product status: 7101SHCPE is active production while 7101SHCKE is obsolete.

Q: What is the difference between the E-Switch 100AWSP1T1B1M2REH and Grayhill 34ASP11B1M2RT?

A: Both parts provide identical electrical and mechanical compatibility with the original 7101SHCKE. The Grayhill part offers extended electrical life (40,000 cycles vs. 30,000 cycles) and is recommended for applications with higher cycle count requirements.

Q: Can I use the Grayhill 34BWSP11B1M2RT in place of the standard 7101SHCKE?

A: Yes. The 34BWSP11B1M2RT maintains identical electrical ratings and mechanical compatibility. The addition of IP67 ingress protection makes it suitable for applications requiring dust and moisture sealing. Verify that the additional environmental protection does not conflict with your application requirements.

Q: Is the A123S1CWCB compatible with circuits designed for the 7101SHCKE?

A: The A123S1CWCB exceeds the original specification (0.5VA at 28V vs. 0.4VA at 20V) and is mechanically compatible. It is suitable for applications where the original specification is met or exceeded. Panel cutout dimensions are not specified for this part; verify mechanical fit before implementation.

Q: Why is the M2012ES1W03/UC listed if it is obsolete?

A: The M2012ES1W03/UC is included because it was referenced in the original part's substitute list and remains available in inventory. It is rated for significantly higher electrical performance (6A at 125V AC). Use this part only in applications requiring elevated electrical ratings and where the mechanical envelope is acceptable.

Q: What are the key parameters I must verify when selecting a substitute?

A: Verify circuit configuration (SPDT), switch function (On-On), mounting type (Panel Mount), termination style (PC Pin), panel cutout dimensions (Circular - 6.35mm Dia), bushing thread (1/4-40), and operating temperature range (-30°C to 85°C minimum). Current and voltage ratings must meet or exceed 0.4VA at 20V AC/DC.

Q: Are all substitute parts RoHS compliant?

A: All recommended active production parts maintain RoHS or ROHS3 compliance. The 7101SHCPE and 34ASP11B1M2RT are ROHS3 compliant. Verify compliance status for your specific regulatory requirements.
