C&K 7101SDAV2LE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101SDAV2LE is a panel-mount toggle switch with SPDT (Single Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The switch features a standard round actuator with epoxy sealed terminals and operates across a temperature range of -30°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101SDAV2LE is determined by the following critical parameters:

Primary Compatibility Criteria:

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

Secondary Compatibility Criteria:

• Current and voltage ratings must meet or exceed application requirements
• Actuator type and length should align with mechanical constraints
• Electrical life rating should support intended duty cycle

Substitute parts are grouped into two categories:

Direct Equivalent: Parts that maintain identical electrical and mechanical specifications with only packaging or compliance status differences.

Functional Equivalent: Parts that satisfy the core circuit, mounting, and mechanical requirements but operate at reduced current/voltage ratings. These are suitable for applications where the full 5A/120V capability is not required.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - Recommended for RoHS3 Compliance:

The C&K 7101SDAV2RE is the direct equivalent to the 7101SDAV2LE, maintaining identical electrical ratings (5A/120V AC, 28V DC), mechanical configuration, and actuator specifications. The 7101SDAV2RE is currently in active production with 1120 units in stock. However, this part is RoHS non-compliant and REACH affected, making it unsuitable for applications requiring environmental compliance certifications.

Functional Equivalents - For Reduced Power Applications:

The E-Switch 100SP1T6B11M7REH, Grayhill 34ASP11B3M7RT, and Electroswitch A123S1YAV2B are functional equivalents suitable for applications where current and voltage requirements do not exceed their respective ratings. All three parts maintain the required SPDT circuit, On-On function, panel mount configuration, and PC pin termination.

• 100SP1T6B11M7REH (E-Switch): Rated 0.4VA at 20V AC/DC with 40,000 electrical life cycles. ROHS3 compliant. Flat anti-rotation actuator differs from standard round type. Suitable for low-power signal switching applications.

• 34ASP11B3M7RT (Grayhill): Rated 0.4VA at 20V AC/DC with 40,000 electrical life cycles. ROHS3 compliant. Standard round actuator with 12.19mm length. Suitable for low-power signal switching applications.

• A123S1YAV2B (Electroswitch): Rated 0.5VA at 28V AC/DC with 60,000 electrical life cycles. RoHS compliant with epoxy sealed terminals. Standard round actuator with 10.41mm length. Panel cutout dimensions not specified. Suitable for low-power DC applications matching the 28V DC rating of the original part.

Compliance Considerations:

For new designs requiring ROHS3 compliance, the E-Switch 100SP1T6B11M7REH or Grayhill 34ASP11B3M7RT are preferred. For applications requiring 28V DC operation with RoHS compliance, the Electroswitch A123S1YAV2B is suitable if panel cutout compatibility can be confirmed.

Frequently Asked Questions (FAQ)

Q: Can the 7101SDAV2RE be used as a direct replacement for the 7101SDAV2LE?

A: The 7101SDAV2RE maintains identical electrical and mechanical specifications, including 5A/120V AC and 28V DC ratings, panel mount configuration, and PC pin termination. However, it is RoHS non-compliant and REACH affected, which may conflict with application requirements. Verify compliance requirements before selection.

Q: What is the difference between the main part and the functional equivalents?

A: The functional equivalents (E-Switch, Grayhill, and Electroswitch models) operate at significantly reduced current and voltage ratings (0.4VA to 0.5VA at 20V to 28V). These parts are suitable only for applications where the full 5A/120V capability is not required. Verify that your application current and voltage demands do not exceed the substitute part ratings.

Q: Are all substitute parts panel-mount compatible with the original 7101SDAV2LE?

A: All substitute parts share the same panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and termination style (PC Pin), ensuring mechanical compatibility. The Electroswitch A123S1YAV2B does not specify panel cutout dimensions; confirm compatibility before use.

Q: Which substitute part offers the best compliance profile?

A: The E-Switch 100SP1T6B11M7REH and Grayhill 34ASP11B3M7RT both carry ROHS3 compliance and REACH unaffected status. The Electroswitch A123S1YAV2B is RoHS compliant but has undefined REACH status. Select based on specific compliance requirements.

Q: What is the impact of reduced electrical life ratings on substitute parts?

A: The functional equivalents (E-Switch and Grayhill models) offer 40,000 electrical life cycles compared to the original part's 100,000 cycles. The Electroswitch model provides 60,000 cycles. Select based on intended duty cycle and expected operational lifespan.

Q: Does actuator length variation affect mechanical fit?

A: Actuator length differences range from 10.41mm to 12.45mm. Verify that panel depth and actuator clearance accommodate the selected substitute part's actuator length to ensure proper mechanical operation.
