Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101L2HAV2ME are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 5A (AC/DC)
• Voltage ratings: 120V AC / 28V DC
• Mounting type: Panel Mount, Right Angle, Vertical
• Termination style: PC Pin
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Operating temperature range: -30°C ~ 85°C

Substitute Categories:

Direct Substitute (Highest Compatibility): C&K 7101L2HAV2SE maintains identical electrical specifications, mounting configuration, and mechanical dimensions. This part represents the active production equivalent within the same manufacturer series.

Similar Substitute (Functional Equivalent): E-Switch 100SP1K1B25M7QEH provides equivalent electrical performance and mechanical compatibility. Differences exist in actuator type (locking lever vs. standard round) and electrical life rating (40,000 cycles vs. 100,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The C&K 7101L2HAV2SE is the primary substitute for the obsolete 7101L2HAV2ME. Both parts share identical electrical ratings, mechanical dimensions, and mounting specifications. The 7101L2HAV2SE maintains active product status and ROHS3 compliance. This part is recommended for applications requiring exact functional equivalence.

For Functional Equivalence: The E-Switch 100SP1K1B25M7QEH provides electrical and mechanical compatibility with the original specification. This part maintains active status and ROHS3 compliance. The locking lever actuator and reduced electrical life (40,000 cycles vs. 100,000 cycles) represent design differences that must be evaluated against application requirements. The 1.4mm increase in actuator length (14.40mm vs. 13.97mm) requires panel clearance verification.

Compliance Considerations: Both substitute parts maintain RoHS compliance. The C&K 7101L2HAV2SE carries REACH Affected status, while the E-Switch 100SP1K1B25M7QEH maintains REACH Unaffected status. Selection should account for supply chain and regulatory requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7101L2HAV2SE directly replace the 7101L2HAV2ME without design modifications?

A: Yes. The 7101L2HAV2SE maintains identical electrical specifications (5A at 120V AC / 28V DC), circuit configuration (SPDT On-On), mechanical dimensions, and mounting configuration. No design modifications are required for direct substitution.

Q: What are the key differences between the C&K 7101L2HAV2SE and E-Switch 100SP1K1B25M7QEH?

A: The primary differences are: (1) Actuator type—C&K uses standard round, E-Switch uses locking lever; (2) Electrical life—C&K rated for 100,000 cycles, E-Switch for 40,000 cycles; (3) Actuator length—C&K 13.97mm, E-Switch 14.40mm; (4) REACH status—C&K is REACH Affected, E-Switch is REACH Unaffected. All other electrical and mechanical parameters are equivalent.

Q: Is the 1.4mm difference in actuator length between the C&K and E-Switch parts significant?

A: Panel clearance must be verified for the application. The E-Switch 100SP1K1B25M7QEH actuator extends 14.40mm compared to 13.97mm for the C&K parts. Confirm that the panel cavity and surrounding components accommodate this dimension before selection.

Q: Does the reduced electrical life of the E-Switch part affect its suitability?

A: The E-Switch 100SP1K1B25M7QEH is rated for 40,000 cycles versus 100,000 cycles for the C&K parts. Application duty cycle determines whether this difference is material. High-frequency switching applications should prioritize the C&K 7101L2HAV2SE.

Q: Are there packaging differences between these parts?

A: The C&K 7101L2HAV2ME and 7101L2HAV2SE are supplied in standard packaging. The E-Switch 100SP1K1B25M7QEH is supplied in bulk packaging. Procurement and inventory management processes should account for this difference.

Q: Which substitute part should be selected for new designs?

A: The C&K 7101L2HAV2SE is recommended for new designs requiring exact functional equivalence to the original specification. The E-Switch 100SP1K1B25M7QEH is suitable when locking lever actuation and reduced cycle life are acceptable for the application.
