Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7401K2CME is determined by strict equivalence across the following critical parameters:

• Circuit configuration (4PDT)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC / 28V DC)
• Mounting type (Panel Mount)
• Switch function (On-On)
• Actuator type and length (Locking Lever, 17.88mm)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (100,000 Cycles)

The 7401K2CSE maintains identical specifications across all these parameters, establishing it as a direct substitute. The primary distinction lies in product status classification and regulatory compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

The 7401K2CSE is the appropriate selection for applications currently specified with the 7401K2CME. The substitute part maintains full electrical and mechanical compatibility while offering the advantage of active product status, ensuring continued availability and supply chain stability.

The 7401K2CSE carries RoHS Compliant certification and is REACH Affected, compared to the 7401K2CME's ROHS3 Compliant status and REACH Unaffected classification. Both parts maintain identical electrical performance specifications, operating temperature ranges, and mechanical interfaces. Selection between these parts should be based on regulatory requirements specific to the end application and geographic market.

Frequently Asked Questions (FAQ)

Q: Can the 7401K2CSE directly replace the 7401K2CME in existing designs?

A: Yes. Both parts share identical electrical ratings (5A at 120V AC / 28V DC), circuit configuration (4PDT), mechanical mounting specifications (panel mount with 6.35mm circular cutout and 1/4-40 bushing thread), and actuator characteristics (locking lever, 17.88mm length). No design modifications are required.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant designations?

A: ROHS3 refers to the third iteration of the Restriction of Hazardous Substances directive. Both designations indicate compliance with RoHS requirements; the specific version designation reflects the regulatory framework under which compliance was certified.

Q: Are there any differences in termination or panel cutout specifications?

A: No. Both parts use PC Pin termination and feature identical panel cutout dimensions (circular, 6.35mm diameter) with matching bushing thread specifications (1/4-40).

Q: What does REACH Affected versus REACH Unaffected mean for component selection?

A: REACH Affected indicates the part contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. REACH Unaffected indicates no such substances are present. Selection depends on end-use application and regulatory jurisdiction requirements.

Q: Is the electrical life rating identical between both parts?

A: Yes. Both the 7401K2CME and 7401K2CSE are rated for 100,000 electrical cycles, ensuring equivalent operational longevity.
