Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101K2AV2ME are identified based on strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Mounting type (Panel Mount, Right Angle, Vertical)
• Termination style (PC Pin)
• Bushing thread specification (1/4-40)
• Panel cutout dimensions (Circular - 6.35mm Dia)

Electrical Compatibility Parameters:

• Current rating equal to or greater than 5A
• Voltage ratings meeting or exceeding 120V AC and 28V DC
• Operating temperature range encompassing -30°C to 85°C

Substitute Categories:

Direct Equivalent: C&K 7101K2AV2SE meets all mechanical and electrical parameters of the main part while maintaining Active product status within the same manufacturer series.

Compatible Alternative: Electroswitch A123P12YAV2G provides SPDT On-On functionality with Panel Mount configuration and PC Pin termination. This part exceeds the electrical specifications (6A at 125V AC) and maintains the required bushing thread and panel cutout compatibility. Differences in actuator type (Flatted vs. Locking Lever) and actuator length (21.34mm vs. 17.88mm) represent mechanical variations that do not affect electrical substitution validity but require panel layout verification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The C&K 7101K2AV2SE is the primary substitute for the 7101K2AV2ME. Both parts share identical mechanical dimensions, electrical ratings, and circuit configuration. The 7101K2AV2SE maintains Active product status and RoHS compliance, eliminating obsolescence concerns while preserving design compatibility.

For Alternative Applications: The Electroswitch A123P12YAV2G provides functional equivalence with enhanced electrical specifications (6A current rating, 125V AC rating). This part is suitable for applications where the higher current and voltage ratings provide design margin. The extended operating temperature range (-30°C to 90°C) accommodates broader environmental conditions. Panel layout verification is required due to the 3.46mm increase in actuator length and the unspecified panel cutout dimensions.

Compliance Considerations: Both substitute parts maintain RoHS compliance. The 7101K2AV2SE carries REACH Affected status, while the A123P12YAV2G lists REACH status as Vendor Undefined. Applications subject to REACH compliance requirements should prioritize the 7101K2AV2SE for regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 7101K2AV2SE directly replace the 7101K2AV2ME without design modifications?

A: Yes. The 7101K2AV2SE is mechanically and electrically identical to the 7101K2AV2ME. Both parts feature the same panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), actuator length (17.88mm), and electrical ratings. No design changes are required.

Q: What are the key differences between the C&K 7101K2AV2SE and the Electroswitch A123P12YAV2G?

A: The primary differences are actuator type (Locking Lever vs. Flatted), actuator length (17.88mm vs. 21.34mm), electrical life rating (100,000 vs. 60,000 cycles), and panel cutout dimension specification. The A123P12YAV2G provides higher current (6A vs. 5A) and voltage (125V vs. 120V AC) ratings. Panel layout compatibility must be verified before substitution.

Q: Is the Electroswitch A123P12YAV2G suitable for applications requiring 100,000 cycle electrical life?

A: No. The A123P12YAV2G is rated for 60,000 electrical cycles, compared to the 100,000 cycle rating of the 7101K2AV2ME and 7101K2AV2SE. Applications with high cycle count requirements should use the C&K 7101K2AV2SE.

Q: Are all substitute parts available in the same packaging format?

A: The 7101K2AV2SE is available in standard packaging matching the original part. The A123P12YAV2G is supplied in Bulk packaging. Procurement specifications should reflect the required packaging format.

Q: What panel layout considerations apply when substituting with the A123P12YAV2G?

A: The A123P12YAV2G actuator extends 3.46mm longer than the original part (21.34mm vs. 17.88mm). Panel cutout dimensions for the A123P12YAV2G are not specified in available documentation. Physical verification of panel clearance and cutout compatibility is required before implementation.
