Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103TCWWLE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-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 rating (IP67)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)

The C&K 7103TCWWRE meets all these criteria and qualifies as a direct substitute within the C&K 7000 series.

Parameter Comparison

Engineering Selection Recommendations

The 7103TCWWRE serves as the functional equivalent to the obsolete 7103TCWWLE, providing identical electrical and mechanical performance across all critical parameters. Both components are rated for identical voltage and current specifications, feature the same circuit configuration, and share identical physical dimensions and mounting characteristics.

The primary distinction between these parts lies in product status and regulatory compliance. The 7103TCWWLE is ROHS3 compliant and REACH unaffected, while the 7103TCWWRE is RoHS non-compliant and REACH affected. The 7103TCWWRE maintains active product status, ensuring continued availability and supply chain support.

Selection between these parts should be based on regulatory requirements applicable to the end application. Applications requiring ROHS3 compliance or REACH unaffected status must retain the 7103TCWWLE where available. Applications without such constraints may transition to the 7103TCWWRE for ongoing procurement.

Frequently Asked Questions (FAQ)

Q: Can the 7103TCWWRE directly replace the 7103TCWWLE in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both components share identical circuit configuration (SPDT), switch function (On-Off-On), current rating (5A AC/DC), voltage ratings (120V AC, 28V DC), mounting type (Panel Mount), actuator specifications, termination style (Wire Wrap), and panel cutout dimensions. Physical installation and electrical performance are equivalent.

Q: What are the differences between these two parts?

A: The primary differences are product status and regulatory compliance. The 7103TCWWLE is obsolete and ROHS3 compliant with REACH unaffected status. The 7103TCWWRE is active, RoHS non-compliant, and REACH affected. All functional and mechanical parameters are identical.

Q: Which part should I specify for new designs?

A: Specify the 7103TCWWRE for new designs, as it maintains active product status and ensures long-term availability. If regulatory requirements mandate ROHS3 compliance or REACH unaffected status, evaluate compliance obligations before part selection.

Q: Are there packaging differences between these parts?

A: The 7103TCWWLE is supplied in standard packaging, while the 7103TCWWRE is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the panel cutout requirement for installation?

A: Both parts require a circular panel cutout of 11.91mm diameter with a 15/32-32 bushing thread. Mechanical installation is identical for both components.

Q: What ingress protection rating do these switches provide?

A: Both the 7103TCWWLE and 7103TCWWRE provide IP67 ingress protection, indicating dust-tight and waterproof operation suitable for harsh environmental conditions.
