C&K 7101L1PD9AV2LE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101L1PD9AV2LE is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This through-hole mounted component features an anti-rotation actuator and epoxy sealed terminals. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: circuit configuration (SPDT), switch function (On-On), mounting type (through hole, right angle, vertical), termination style (PC pin), operating temperature range (-30°C to 85°C), and environmental compliance (RoHS, REACH, ECCN).

The substitute parts are grouped into two categories:

Direct Equivalent: Parts that maintain identical electrical ratings (5A at 120V AC / 28V DC), mechanical form factor, and actuator specifications. These parts are fully interchangeable without circuit redesign.

Similar Substitutes: Parts that share the same circuit topology, mounting configuration, and termination style but operate at reduced electrical ratings (0.4VA at 20V AC/DC). These parts require application verification to confirm suitability for lower power environments.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification Required):

The C&K 7101L1PD9AV2RE is the primary direct equivalent. It maintains identical electrical ratings (5A at 120V AC / 28V DC), mechanical configuration, and actuator specifications. The part is active in production status, ensuring supply continuity. RoHS compliance is confirmed. REACH status differs (REACH Affected vs. REACH Unaffected), which may require documentation review for specific regulatory jurisdictions.

For Applications with Reduced Power Requirements:

The E-Switch 100SP1T3B4M7RE and Grayhill Inc. 34ASP13B4M7RT are suitable only for applications operating at 0.4VA maximum at 20V AC/DC. These parts share identical circuit topology, mounting configuration, and termination style. Actuator length is reduced (13.97mm vs. 18.04mm), and electrical life is lower (40,000 cycles vs. 100,000 cycles). Both parts are active in production and RoHS compliant. Selection between these two similar substitutes depends on supply availability and lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7101L1PD9AV2RE be used as a direct replacement for the 7101L1PD9AV2LE?

A: Yes. Both parts share identical electrical ratings (5A at 120V AC / 28V DC), circuit configuration (SPDT), switch function (On-On), mounting type (through hole, right angle, vertical), actuator specifications (anti-rotation, 18.04mm length), and termination style (PC pin). The 7101L1PD9AV2RE is active in production, addressing the obsolete status of the original part.

Q: What are the limitations of the E-Switch 100SP1T3B4M7RE and Grayhill 34ASP13B4M7RT substitutes?

A: These parts operate at significantly reduced electrical ratings (0.4VA at 20V AC/DC compared to 5A at 120V AC / 28V DC). Electrical life is also reduced to 40,000 cycles versus 100,000 cycles. Actuator length is shorter (13.97mm vs. 18.04mm). These parts are suitable only for low-power signal switching applications and require verification that the application does not exceed the reduced voltage and current specifications.

Q: Are there mechanical compatibility concerns when substituting parts?

A: The direct equivalent (7101L1PD9AV2RE) maintains identical mechanical form factor and actuator length. The similar substitutes (100SP1T3B4M7RE and 34ASP13B4M7RT) have shorter actuators (13.97mm vs. 18.04mm) and different actuator types (standard round vs. anti-rotation). Panel cutout dimensions and mounting hole spacing must be verified for the similar substitutes.

Q: What compliance certifications should be verified before selection?

A: All substitute parts are RoHS compliant. The main part and direct equivalent are RoHS3 compliant. REACH status varies: the main part is REACH Unaffected, while the direct equivalent is REACH Affected. For applications in specific regulatory jurisdictions, REACH compliance documentation should be obtained from the manufacturer. All parts carry ECCN EAR99 classification.

Q: How do the electrical life ratings affect component selection?

A: The main part and direct equivalent are rated for 100,000 electrical cycles. The similar substitutes are rated for 40,000 cycles. For applications requiring frequent switching or long operational life, the higher-rated parts are preferred. For applications with infrequent switching or limited operational cycles, the similar substitutes may be acceptable.
