Equivalent & Substitute Parts for C&K 7105SDAV2LE Toggle Switch

Part Overview

The C&K 7105SDAV2LE is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component features a panel-mount design with right-angle vertical orientation and Mom-Off-Mom switching function. The part is currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible switching functionality.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit Configuration: SPDT (all substitutes must match)
• Switch Function: Mom-Off-Mom (all substitutes must match)
• Mounting Type: Panel Mount, Right Angle, Vertical (all substitutes must match)
• Panel Cutout Dimensions: Circular - 6.35mm Dia (all substitutes must match)
• Bushing Thread: 1/4-40 (all substitutes must match)
• Termination Style: PC Pin (all substitutes must match)

Substitutes are grouped into two categories:

Direct Equivalent: Parts with identical electrical ratings (5A at 120V AC / 28V DC) and active product status.

Functional Equivalent: Parts with reduced electrical ratings but matching mechanical and circuit specifications. These are suitable for applications where the lower current or voltage ratings are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitutes

The C&K 7105SDAV2RE is the primary direct equivalent. It maintains identical electrical ratings (5A at 120V AC / 28V DC), matching mechanical specifications, and active product status. This part is available in inventory and carries RoHS compliance certification. The 7105SDAV2RE is the preferred choice for direct replacement in applications requiring the full 5A current capacity.

The E-Switch 100SP4T1B1M7QEH provides equivalent electrical performance (5A at 120V AC / 28V DC) with active product status and ROHS3 compliance. This part features a slightly shorter actuator length (10.41mm versus 12.45mm) and is available in bulk packaging. Mechanical compatibility is confirmed through matching panel cutout dimensions and bushing thread specifications.

Functional Equivalent Substitutes

The Grayhill 34ASP41B1M7RT, Electroswitch A127P32DAV2B, and Electroswitch A127S1YAV2B are functional equivalents with reduced electrical ratings. These parts maintain SPDT circuit configuration, Mom-Off-Mom switching function, and matching mechanical specifications. Selection of these parts is appropriate only for applications where the reduced current and voltage ratings are acceptable.

The Grayhill 34ASP41B1M7RT is rated for 0.4VA at 20V AC/DC. The Electroswitch A127P32DAV2B and A127S1YAV2B are each rated for 0.5VA at 28V AC/DC. All three parts carry active product status and RoHS compliance.

Compliance Considerations

All substitute parts maintain RoHS compliance. The 7105SDAV2LE and 100SP4T1B1M7QEH carry ROHS3 certification. The 7105SDAV2RE, 34ASP41B1M7RT, A127P32DAV2B, and A127S1YAV2B carry RoHS certification. All parts are classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7105SDAV2RE directly replace the 7105SDAV2LE?

A: Yes. The 7105SDAV2RE is a direct equivalent with identical electrical ratings (5A at 120V AC / 28V DC), matching circuit configuration (SPDT), and identical mechanical specifications including panel cutout dimensions and bushing thread. The primary difference is active product status versus obsolete status.

Q: What is the difference between direct equivalent and functional equivalent substitutes?

A: Direct equivalents maintain identical electrical ratings and are suitable for any application previously using the 7105SDAV2LE. Functional equivalents have reduced current or voltage ratings and are suitable only for applications where these lower ratings are acceptable. The Grayhill and Electroswitch parts are functional equivalents with significantly lower current ratings.

Q: Are there mechanical compatibility concerns with the E-Switch 100SP4T1B1M7QEH?

A: The E-Switch part has a shorter actuator length (10.41mm versus 12.45mm). Panel cutout dimensions and bushing thread specifications are identical. Verify that the reduced actuator length is compatible with your panel thickness and actuator engagement requirements.

Q: Do the Electroswitch parts have specified panel cutout dimensions?

A: The A127P32DAV2B and A127S1YAV2B do not have panel cutout dimensions specified in the provided data. Confirm mechanical compatibility with the 6.35mm circular cutout and 1/4-40 bushing thread before selection.

Q: What is the impact of the reduced electrical life in the main part?

A: The 7105SDAV2LE is rated for 40,000 electrical cycles. The Electroswitch A127P32DAV2B and A127S1YAV2B are rated for 60,000 cycles, providing extended operational life. The E-Switch and Grayhill parts maintain 40,000 cycle ratings matching the original part.

Q: Are all substitutes available in the same packaging as the original?

A: The 7105SDAV2LE packaging is not specified in the provided data. The 7105SDAV2RE packaging is not specified. The E-Switch 100SP4T1B1M7QEH is available in bulk packaging. The Electroswitch parts are available in bulk packaging. Confirm packaging requirements for your procurement process.
