Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7401TV41LE is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (4PDT), switch function (On-On), current rating (5A AC/DC), voltage ratings (120V AC / 28V DC), and electrical life (100,000 cycles) must remain unchanged.

Mechanical Parameters: Mounting type (panel mount), actuator type (standard round), actuator length (17.45mm), termination style (PC pin), panel cutout dimensions (circular 11.91mm diameter), and bushing thread (15/32-32) must be identical.

Environmental Parameters: Operating temperature range (-30°C to 85°C) and base product number (7401TV) must match.

Compliance Parameters: RoHS and REACH certifications must be maintained or upgraded.

The C&K 7401TV41RE qualifies as a direct substitute based on complete alignment with all electrical, mechanical, and environmental parameters. The primary distinction is product status: the 7401TV41LE is obsolete while the 7401TV41RE is active, and REACH compliance status differs (REACH Unaffected vs. REACH Affected).

Parameter Comparison

Engineering Selection Recommendations

The C&K 7401TV41RE is the direct substitute for the obsolete 7401TV41LE. Both components maintain identical electrical and mechanical specifications, ensuring functional equivalence in circuit applications.

For New Designs: The 7401TV41RE is the appropriate selection due to its active product status and current availability. This component meets RoHS compliance requirements and is subject to REACH regulations, reflecting current regulatory standards.

For Legacy System Maintenance: The 7401TV41RE provides full compatibility with existing installations designed for the 7401TV41LE. No circuit modifications or panel alterations are required due to identical mechanical and electrical parameters.

Compliance Considerations: Both parts maintain RoHS compliance. The 7401TV41RE's REACH Affected status indicates it is subject to REACH chemical substance regulations, whereas the 7401TV41LE was REACH Unaffected. This distinction is relevant for supply chain documentation and regulatory compliance tracking in applications subject to REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7401TV41RE be used as a direct replacement for the 7401TV41LE?

A: Yes. The 7401TV41RE is a direct substitute. All electrical parameters (5A at 120V AC / 28V DC, 4PDT configuration), mechanical specifications (panel mount, 11.91mm circular cutout, 15/32-32 bushing thread), and environmental ratings (-30°C to 85°C operating range) are identical.

Q: What is the primary reason to transition from the 7401TV41LE to the 7401TV41RE?

A: The 7401TV41LE is obsolete. The 7401TV41RE is the active equivalent from C&K's 7000 series, ensuring continued availability and supply chain reliability.

Q: Are there any panel modification requirements when substituting the 7401TV41RE for the 7401TV41LE?

A: No. Both components share identical panel cutout dimensions (circular 11.91mm diameter) and bushing thread specifications (15/32-32), eliminating the need for mechanical panel modifications.

Q: Do the RoHS compliance levels differ between these parts?

A: Both parts are RoHS compliant. The 7401TV41LE is ROHS3 compliant while the 7401TV41RE is RoHS compliant, representing equivalent compliance with current RoHS standards.

Q: What is the significance of the REACH status difference?

A: The 7401TV41RE is REACH Affected, meaning it is subject to REACH chemical substance regulations. The 7401TV41LE was REACH Unaffected. For applications in REACH-regulated markets, the 7401TV41RE requires appropriate supply chain documentation and compliance verification.

Q: Are the electrical life ratings equivalent?

A: Yes. Both components are rated for 100,000 electrical cycles, providing identical operational longevity in switching applications.
