Engineering Selection Recommendations
Direct Equivalent - Recommended for Obsolete Part Replacement:
The C&K 7101SPYCRE is the primary substitute for the obsolete 7101SPYCLE. Both parts share identical electrical specifications (5A at 120V AC / 28V DC), mechanical configuration, and actuator design. The 7101SPYCRE maintains the same 100,000 electrical cycle rating and operating temperature range. The part is currently in active production status with higher inventory availability (1006 units). RoHS compliance is maintained, though REACH status differs (REACH Affected vs. REACH Unaffected). This difference does not affect functional compatibility.
Cross-Manufacturer Alternatives:
Grayhill Inc. 34ASP11B1M2QT meets all primary substitution criteria with identical current and voltage ratings. The part features a standard round actuator instead of anti-rotation design and supports 40,000 electrical cycles. This represents a reduced cycle life compared to the original specification.
Grayhill Inc. 34ASP11B1M2RT does not meet substitution requirements. The 0.4VA current rating and 20V AC/DC voltage ratings fall below the minimum thresholds established for the 7101SPYCLE.
Electroswitch A123S1CWCG, A123S1DCQ, and A123S1YCQ all provide 6A current capacity at 125V AC, exceeding the original 5A at 120V AC specification. These parts feature standard round actuators and 60,000 electrical cycle ratings. Panel cutout dimensions are not specified for these alternatives. Operating temperature range extends to 90°C, providing additional margin beyond the original -30°C to 85°C specification.
Compliance Considerations:
All substitute parts maintain RoHS compliance. REACH status varies across manufacturers and does not affect functional substitution eligibility. Selection should account for specific regulatory requirements of the end application.
Frequently Asked Questions (FAQ)
Q: Can the 7101SPYCRE directly replace the obsolete 7101SPYCLE without design modification?
A: Yes. The 7101SPYCRE is a direct equivalent with identical electrical ratings (5A at 120V AC / 28V DC), mechanical mounting configuration, PC pin termination, 1/4-40 bushing thread, and 6.35mm circular panel cutout. Both parts support the same operating temperature range and feature epoxy sealed terminals. No design modification is required.
Q: What is the primary difference between the C&K 7101SPYCRE and Grayhill 34ASP11B1M2QT?
A: Both parts meet the core SPDT On-On configuration with 5A at 120V AC / 28V DC ratings and identical mechanical mounting. The key difference is actuator design: the 7101SPYCRE features anti-rotation design matching the original 7101SPYCLE, while the 34ASP11B1M2QT uses a standard round actuator. Additionally, the 34ASP11B1M2QT supports 40,000 electrical cycles compared to 100,000 cycles for the 7101SPYCRE.
Q: Why is the Grayhill 34ASP11B1M2RT not suitable as a substitute?
A: The 34ASP11B1M2RT has a current rating of 0.4VA and voltage ratings of 20V AC/DC, both of which fall below the minimum requirements of the 7101SPYCLE (5A at 120V AC / 28V DC). This part does not meet the electrical substitution criteria.
Q: Can Electroswitch A123S1 series parts replace the 7101SPYCLE?
A: The Electroswitch A123S1CWCG, A123S1DCQ, and A123S1YCQ meet all primary substitution criteria with SPDT On-On configuration, PC pin termination, 1/4-40 bushing thread, and compatible operating temperature range. These parts provide higher current capacity (6A vs. 5A) and voltage ratings (125V AC vs. 120V AC). However, panel cutout dimensions are not specified for these alternatives, requiring verification against your specific panel mounting requirements. Electrical life is rated at 60,000 cycles, lower than the original 100,000 cycles.
Q: What packaging options are available for substitute parts?
A: All substitute parts listed are supplied in bulk packaging. The original 7101SPYCLE was supplied with unspecified packaging. Verify packaging requirements with your procurement process.
Q: Are there compliance differences between the main part and substitutes?
A: All parts maintain RoHS compliance. REACH status varies: the 7101SPYCLE and Grayhill parts are REACH Unaffected, while the C&K 7101SPYCRE is REACH Affected and Electroswitch parts show Vendor Undefined status. Verify REACH compliance requirements for your specific application and regulatory jurisdiction.
Q: What is the inventory status for substitute parts?
A: The C&K 7101SPYCRE has 1006 units in stock. Grayhill 34ASP11B1M2QT has 1047 units available. Electroswitch A123S1 series parts have between 697 and 951 units in stock across the three variants. Verify current inventory before finalizing procurement decisions.
