Key Parameters

Substitute Part Grouping Explanation

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

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Standard Round, 17.45mm length)
• Termination style (Wire Wrap)
• Panel cutout dimensions (Circular 11.91mm Dia)
• Bushing thread (15/32-32)
• Ingress protection (IP67)
• Operating temperature range (-30°C to 85°C)
• Electrical life (100,000 Cycles)

The C&K 7101TCWWRE meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7101TCWWRE is the qualified substitute for the obsolete 7101TCWWLE. Both components maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the 7101TCWWLE is obsolete while the 7101TCWWRE is active and currently available in inventory (667 pcs in stock).

For new designs or system replacements, the 7101TCWWRE should be selected. Both parts carry RoHS compliance certifications appropriate for their respective manufacturing periods. The 7101TCWWRE is REACH Affected, while the 7101TCWWLE is REACH Unaffected; however, this distinction does not affect functional substitution within equivalent electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 7101TCWWRE directly replace the 7101TCWWLE in existing installations?

A: Yes. The 7101TCWWRE is electrically and mechanically equivalent to the 7101TCWWLE across all specified parameters, including circuit configuration, current and voltage ratings, mounting dimensions, and termination style.

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

A: ROHS3 refers to the third iteration of the RoHS directive. Both designations indicate compliance with RoHS requirements; the difference reflects the regulatory framework applicable at the time of component certification.

Q: Are there any inventory considerations when selecting between these parts?

A: The 7101TCWWLE is obsolete with 719 pcs in stock. The 7101TCWWRE is active with 667 pcs in stock. For ongoing supply assurance, the 7101TCWWRE is the recommended selection.

Q: Do the panel cutout dimensions remain identical for both parts?

A: Yes. Both the 7101TCWWLE and 7101TCWWRE require a circular 11.91mm diameter cutout with 15/32-32 bushing thread, ensuring mechanical interchangeability in panel installations.

Q: What environmental conditions are these switches rated for?

A: Both parts operate across -30°C to 85°C and maintain IP67 ingress protection (dust tight and waterproof), with epoxy sealed terminals for enhanced environmental resistance.
