Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Primary Compatibility Criteria:

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

Electrical Compatibility Criteria:

• Current rating must equal or exceed 7.5A
• AC voltage rating must equal or exceed 125V
• DC voltage rating must equal or exceed 28V

Secondary Considerations:

• Actuator type and length variations are acceptable if mechanical envelope permits
• Ingress protection rating variations are acceptable
• Electrical life variations are acceptable if minimum 30,000 cycles is maintained

Substitute parts are grouped into two categories:

Direct Substitute (Fully Compatible): E201SYCRE maintains identical electrical ratings and mechanical specifications with active product status.

Functional Substitutes (Electrical Derating Required): E-Switch 100 series and Grayhill 34A series parts meet mechanical compatibility but operate at reduced current ratings (5A or 0.4VA) or voltage ratings (120V AC or 20V AC/DC). These require circuit analysis to confirm suitability for the intended application.

Parameter Comparison

Engineering Selection Recommendations

First Priority: C&K E201SYCRE

E201SYCRE is the direct substitute for E201SYCLE. It maintains identical electrical ratings (7.5A at 125V AC, 28V DC), mechanical specifications, and panel mount configuration. The part is active in production with RoHS compliance. REACH status differs (REACH Affected vs. REACH Unaffected), which may require regulatory review depending on end-use application and regional requirements.

Secondary Priority: Grayhill 34ADP11B1M2QT

34ADP11B1M2QT provides mechanical and functional compatibility with reduced current rating (5A vs. 7.5A). AC voltage rating matches at 125V. This part is suitable for applications where the circuit load does not exceed 5A. ROHS3 compliance and 40,000-cycle electrical life are maintained.

Tertiary Priority: E-Switch 100DP1T1B1M2QEH

100DP1T1B1M2QEH offers mechanical compatibility with current rating of 5A and AC voltage of 120V. This part is suitable for applications operating below 5A and 120V AC. Electrical life is 40,000 cycles. Ingress protection rating is not specified.

Not Recommended for Direct Substitution:

Parts with 0.4VA current rating (100DP1T1B1M2REH, 34ADP11B1M2RT) and 20V AC/DC voltage rating represent significant electrical derating and are suitable only for low-power signal switching applications, not for the 7.5A, 125V AC design envelope of the original part.

Frequently Asked Questions (FAQ)

Q: Can E201SYCRE directly replace E201SYCLE without circuit modification?

A: Yes. E201SYCRE maintains identical electrical ratings (7.5A at 125V AC, 28V DC), circuit configuration (DPDT On-On), and mechanical specifications (panel mount, 6.35mm cutout, 1/4-40 bushing, PC Pin termination). The only difference is REACH status, which requires regulatory assessment based on your application and region.

Q: What is the difference between the E-Switch 100 series and Grayhill 34A series substitutes?

A: Both manufacturers offer DPDT panel-mount switches with compatible mechanical specifications. The primary difference is current rating: Grayhill 34ADP11B1M2QT is rated for 5A (closer to the original 7.5A), while E-Switch 100DP1T1B1M2QEH is also rated for 5A. Both are suitable only for applications not exceeding 5A. Grayhill maintains 125V AC rating; E-Switch is rated for 120V AC.

Q: Why are some substitute parts rated for 0.4VA instead of 5A or 7.5A?

A: The 0.4VA rating indicates these parts are designed for low-power signal switching applications (typically under 1A). These parts are not suitable for the 7.5A design envelope of the E201SYCLE and should not be selected unless your application requires only signal-level switching.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry either RoHS or ROHS3 compliance certification. The original E201SYCLE is ROHS3 compliant. E201SYCRE is RoHS compliant. All E-Switch and Grayhill parts are ROHS3 compliant.

Q: What is the impact of different actuator lengths on mechanical compatibility?

A: The original E201SYCLE has a 10.16mm actuator length. Substitute parts range from 10.41mm to 12.30mm. These variations are acceptable if the panel cutout and surrounding mechanical envelope accommodate the longer actuator. Verify clearance in your specific panel design before selection.

Q: Can I use a substitute part rated for 120V AC instead of 125V AC?

A: The E-Switch 100 series parts are rated for 120V AC versus the original 125V AC rating. This represents a 4% voltage reduction. Suitability depends on your circuit design and whether 120V AC operation is acceptable. For applications requiring full 125V AC rating, select E201SYCRE or Grayhill 34ADP11B1M2QT.

Q: What does IP57 versus IP67 ingress protection mean for my application?

A: IP57 (original E201SYCLE and E201SYCRE) provides dust protection and waterproof operation. IP67 (E-Switch 100AWDP1T1B1M2QEH) provides dust-tight and waterproof operation, offering enhanced protection. If your application requires only IP57 protection, either rating is acceptable. If IP57 is a minimum requirement, IP67 exceeds it.

Q: How does electrical life affect part selection?

A: The original E201SYCLE is rated for 40,000 cycles. Most substitutes maintain this rating. E-Switch 100AWDP1T1B1M2QEH is rated for 30,000 cycles, representing a 25% reduction. For applications with high cycle counts, select parts with 40,000-cycle ratings.
