Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Circuit configuration (SPDT required)
• Switch function (On-On operation)
• Mounting type (Panel Mount)
• Termination style (PC Pin)
• Bushing thread specification (1/4-40)
• Electrical ratings (current and voltage must meet or exceed application requirements)

Substitute Categories:

Direct Equivalent: 7101SPCWCRES2 (C&K) maintains identical electrical specifications, mechanical interface, and circuit topology as the main part. This substitute differs only in actuator sealing method (epoxy sealed terminals vs. satin chrome) and product status (active vs. obsolete).

Similar Substitutes: A123S1DCQ, A123S1CWCG, A123S1CWCQ, and A123M1CWCB (Electroswitch) share core functional parameters including SPDT circuit, On-On function, panel mount configuration, PC pin termination, and 1/4-40 bushing thread. These parts operate within compatible voltage and current ranges for the specified application domain.

Parameter Comparison

Engineering Selection Recommendations

7101SPCWCRES2 (C&K): This direct equivalent is the primary substitute for the obsolete 7101SPCWCLES2. It maintains identical electrical specifications, mechanical interface dimensions, and circuit topology. The part is currently in active production status with 1073 units in stock. RoHS compliance is confirmed. This substitute is suitable for direct replacement in existing designs without circuit modification.

A123S1DCQ, A123S1CWCG, A123S1CWCQ (Electroswitch): These similar substitutes provide equivalent SPDT functionality with enhanced current ratings (6A vs. 5A) and slightly higher AC voltage rating (125V vs. 120V). All three parts are active production items with confirmed RoHS compliance. Selection among these three variants depends on specific ingress protection requirements and actuator length specifications. A123S1CWCG and A123S1CWCQ are functionally identical with splash-proof ingress protection and 10.41mm actuator length. A123S1DCQ offers the same electrical specifications without specified ingress protection rating.

A123M1CWCB (Electroswitch): This substitute is suitable only for applications with reduced power requirements. The 0.5VA current rating and 28V AC maximum voltage limit this part to low-power control circuits. This substitute is not appropriate for applications requiring the full 5A/120V capability of the original part.

Frequently Asked Questions (FAQ)

Q: Can 7101SPCWCRES2 be used as a direct replacement for 7101SPCWCLES2?

A: Yes. Both parts share identical electrical ratings (5A, 120V AC, 28V DC), SPDT circuit configuration, On-On function, panel mount interface, PC pin termination, and 1/4-40 bushing thread. The primary difference is actuator sealing method and product status. 7101SPCWCRES2 is the recommended substitute for obsolete 7101SPCWCLES2.

Q: What are the key differences between C&K and Electroswitch substitutes?

A: C&K 7101SPCWCRES2 maintains identical specifications to the original part. Electroswitch A123 series parts offer higher current ratings (6A) and extended operating temperature range (-30°C to 90°C vs. -30°C to 85°C), but feature reduced electrical life (60,000 vs. 100,000 cycles) and lower ingress protection ratings (splash proof vs. IP67).

Q: Is A123M1CWCB compatible with applications requiring 5A at 120V?

A: No. A123M1CWCB is rated for 0.5VA maximum and 28V AC maximum voltage. This part is suitable only for low-power control applications and cannot replace the 5A/120V rated 7101SPCWCLES2.

Q: What is the significance of the panel cutout dimension difference?

A: The original 7101SPCWCLES2 specifies a circular 6.35mm diameter panel cutout. Electroswitch A123 series parts do not specify panel cutout dimensions in the provided data. Physical verification of panel mounting compatibility is required before substitution in existing panel assemblies.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitutes (7101SPCWCRES2, A123S1DCQ, A123S1CWCG, A123S1CWCQ, A123M1CWCB) are confirmed RoHS compliant. The original 7101SPCWCLES2 is RoHS3 compliant.

Q: What is the impact of reduced electrical life in Electroswitch substitutes?

A: Electroswitch A123 series parts are rated for 60,000 electrical cycles compared to 100,000 cycles for C&K parts. Applications requiring extended operational life or frequent switching cycles should prioritize 7101SPCWCRES2 to maintain equivalent reliability characteristics.
