Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT
• Switch Function: Must be On-On
• Mounting Type: Must be Panel Mount, Right Angle, Vertical
• Panel Cutout Dimensions: Must be Circular - 6.35mm Dia
• Bushing Thread: Must be 1/4-40
• Termination Style: Must be PC Pin
• Operating Temperature Range: Must accommodate -30°C to 85°C minimum
• Voltage and Current Ratings: Must meet or exceed 5A at 120V AC and 28V DC

Substitute parts are grouped into two categories:

Direct Equivalent: Parts from the same manufacturer (C&K) with identical electrical and mechanical specifications, differing only in product status or compliance certifications.

Functional Equivalent: Parts from alternative manufacturers meeting all critical electrical and mechanical parameters, with allowable variations in actuator type, actuator length, and electrical life, provided they do not compromise application performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: C&K 7101P3DAV2RE

The C&K 7101P3DAV2RE is the direct equivalent replacement for the obsolete 7101P3DAV2LE. Both parts share identical electrical ratings (5A at 120V AC and 28V DC), mechanical specifications, and mounting configuration. The 7101P3DAV2RE is currently in active production status with 742 units in stock. This part maintains the same 100,000 cycle electrical life and operating temperature range. RoHS compliance is confirmed. This substitution requires no design modification and provides the highest compatibility assurance.

Secondary Recommendation: E-Switch 100SP1K1B25M7QEH

The E-Switch 100SP1K1B25M7QEH meets all critical electrical and mechanical parameters with 5A current rating at 120V AC and 28V DC. Panel mount configuration, cutout dimensions, bushing thread, and termination style are identical. Differences include locking lever actuator type (versus flat anti-rotation) and 14.40mm actuator length (versus 13.21mm). Electrical life is rated at 40,000 cycles. This part is ROHS3 compliant and currently in active production with 1176 units in stock. Application suitability depends on actuator type compatibility with the panel interface.

Alternative Consideration: Grayhill 34ASP11B3M7RT and Electroswitch A123S1YAV2B

These parts do not meet the electrical rating requirements of the main part. The Grayhill 34ASP11B3M7RT is rated for 0.4VA at 20V AC/DC, and the Electroswitch A123S1YAV2B is rated for 0.5VA at 28V DC. These parts are suitable only for applications with reduced voltage and current requirements. Panel cutout dimensions and bushing thread specifications are compatible. These substitutions require application-level verification that reduced electrical ratings are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7101P3DAV2RE directly replace the obsolete 7101P3DAV2LE without any modifications?

A: Yes. The 7101P3DAV2RE is electrically and mechanically identical to the 7101P3DAV2LE. Both parts feature 5A at 120V AC and 28V DC ratings, identical panel mount configuration, and 100,000 cycle electrical life. No design or installation modifications are required.

Q: What are the key differences between the C&K 7101P3DAV2RE and the E-Switch 100SP1K1B25M7QEH?

A: Both parts meet the 5A at 120V AC and 28V DC electrical requirements and share identical panel cutout dimensions and bushing thread specifications. The primary differences are actuator type (flat anti-rotation versus locking lever), actuator length (13.21mm versus 14.40mm), and electrical life (100,000 versus 40,000 cycles). The E-Switch part is suitable if the locking lever actuator and reduced cycle life are compatible with the application.

Q: Why are the Grayhill 34ASP11B3M7RT and Electroswitch A123S1YAV2B listed as substitutes if they have lower electrical ratings?

A: These parts are listed because they meet the mechanical and mounting specifications (panel mount, right angle vertical, 1/4-40 bushing thread, PC pin termination). However, their reduced voltage and current ratings (0.4VA at 20V and 0.5VA at 28V respectively) make them suitable only for applications with lower power requirements. They cannot be used as direct replacements for the main part in applications requiring 5A at 120V AC.

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

A: The circular 6.35mm diameter panel cutout dimension determines physical compatibility with the panel interface. All recommended substitutes share this specification, ensuring mechanical fit without panel modification. The Electroswitch A123S1YAV2B does not specify panel cutout dimensions, requiring verification before selection.

Q: How does electrical life rating affect part selection?

A: Electrical life rating indicates the number of switching cycles the part is rated to perform before degradation. The main part and C&K 7101P3DAV2RE are rated for 100,000 cycles. The E-Switch and Grayhill parts are rated for 40,000 cycles, and the Electroswitch part for 60,000 cycles. Selection should account for the expected number of switching operations over the product lifetime.

Q: Are all substitute parts RoHS compliant?

A: All listed parts are RoHS compliant. The main part and E-Switch part are ROHS3 compliant. The C&K 7101P3DAV2RE, Grayhill 34ASP11B3M7RT, and Electroswitch A123S1YAV2B are RoHS compliant. Compliance status should be verified against specific regulatory requirements for the end application.
