Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7105MPCWWLES is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current and voltage ratings (5A AC/DC, 120V AC, 28V DC)
• Mounting type and panel interface (Panel Mount, 6.35mm circular cutout, 1/4-40 bushing thread)
• Termination style (Wire Wrap)
• Ingress protection rating (IP67)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (40,000 cycles)
• Actuator specifications (Anti-Rotation, 5.08mm length, Brass Chrome Plated)

The C&K 7105MPCWWRES qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction is product status: the 7105MPCWWRES is active production, whereas the 7105MPCWWLES is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7105MPCWWRES is a direct functional equivalent to the obsolete 7105MPCWWLES. Both components meet identical electrical specifications, mechanical interface requirements, and environmental performance criteria. The 7105MPCWWRES maintains active production status, ensuring availability for replacement and new applications.

Compliance considerations: The 7105MPCWWLES carries ROHS3 Compliant and REACH Unaffected designations. The 7105MPCWWRES is RoHS Compliant with REACH Affected status. Both components satisfy regulatory requirements for their respective designations. Selection between these parts should be based on supply chain availability and specific regulatory requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can the 7105MPCWWRES directly replace the 7105MPCWWLES in existing assemblies?

A: Yes. Both components share identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (SPDT), switch function (Mom-Off-Mom), and mechanical interface specifications (6.35mm panel cutout, 1/4-40 bushing thread, Wire Wrap termination). No circuit modifications or panel rework are required.

Q: What is the difference between these two parts?

A: The primary difference is product status. The 7105MPCWWLES is obsolete; the 7105MPCWWRES is in active production. Secondary differences exist in RoHS and REACH compliance designations, which do not affect functional performance.

Q: Are there any actuator or terminal differences between these parts?

A: The 7105MPCWWLES features a satin chrome actuator. The 7105MPCWWRES features epoxy sealed terminals. Both maintain identical actuator specifications (Anti-Rotation, 5.08mm length, Brass Chrome Plated material) and Wire Wrap termination style. These differences do not affect electrical or mechanical compatibility.

Q: What ingress protection rating do these switches provide?

A: Both the 7105MPCWWLES and 7105MPCWWRES are rated IP67, providing dust-tight and waterproof protection suitable for harsh environmental applications.

Q: What is the electrical life expectancy?

A: Both components are rated for 40,000 electrical cycles, establishing the expected operational lifespan under specified switching conditions.
