Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101P3CWWME2 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Circuit configuration (SPDT), switch function (On-On), current rating (5A AC/DC), voltage ratings (120V AC / 28V DC)
• Mechanical Compatibility: Mounting type (panel mount), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), actuator type (flat anti-rotation), actuator length (11.43mm)
• Environmental & Operational: Ingress protection (IP67), operating temperature range (-30°C to 85°C), electrical life (100,000 cycles)
• Termination: Wire wrap termination style

The C&K 7101P3CWWSE2 meets all substitution criteria across these parameters, with the primary distinction being product status (active vs. obsolete) and terminal sealing method (epoxy sealed vs. standard).

Parameter Comparison

Engineering Selection Recommendations

The C&K 7101P3CWWSE2 is the direct functional equivalent for the obsolete 7101P3CWWME2. Both components share identical electrical ratings, mechanical dimensions, and operational specifications within the 7000 series platform.

Product Status Consideration: The 7101P3CWWSE2 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete 7101P3CWWME2.

Compliance Differences: The 7101P3CWWSE2 carries RoHS compliance designation and is REACH affected, whereas the 7101P3CWWME2 is RoHS3 compliant and REACH unaffected. Design teams must verify compliance requirements against applicable regulatory frameworks for their specific application and market.

Terminal Sealing: The substitute part features epoxy sealed terminals compared to the main part's standard termination. This enhancement provides improved environmental protection in high-moisture or corrosive environments while maintaining wire wrap termination compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 7101P3CWWSE2 directly replace the 7101P3CWWME2 in existing designs?

A: Yes. Both components are mechanically and electrically identical across all critical parameters: SPDT configuration, 5A rating at 120V AC / 28V DC, panel mount with 6.35mm circular cutout, 1/4-40 bushing thread, flat anti-rotation actuator at 11.43mm length, wire wrap termination, IP67 ingress protection, and -30°C to 85°C operating range. Panel cutout and mounting hardware require no modification.

Q: What is the difference between the two parts?

A: The primary differences are product status (active vs. obsolete), terminal sealing method (epoxy sealed vs. standard), and regulatory compliance designations (RoHS and REACH status). Electrical and mechanical performance are equivalent.

Q: Are there any compatibility concerns with wire wrap termination?

A: No. Both parts utilize identical wire wrap termination style, ensuring compatibility with existing PCB layouts, connector interfaces, and assembly processes.

Q: Does the epoxy sealed terminal feature on the substitute part affect performance?

A: The epoxy sealed terminals on the 7101P3CWWSE2 provide enhanced environmental protection without altering electrical performance or mechanical compatibility. This feature is beneficial in applications with exposure to moisture, salt spray, or other corrosive environments.

Q: Which part should be selected for new designs?

A: The 7101P3CWWSE2 is the appropriate selection for new designs due to its active production status and improved terminal sealing. The 7101P3CWWME2 should be reserved for legacy system maintenance only.

Q: Are there differences in RoHS or REACH compliance between these parts?

A: Yes. The 7101P3CWWSE2 is RoHS compliant and REACH affected, while the 7101P3CWWME2 is RoHS3 compliant and REACH unaffected. Verify compliance requirements against your application's regulatory framework before final component selection.
