Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 7101P3DW4LE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current and voltage ratings (5A AC/DC, 120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Flat Anti-Rotation, 13.21mm length)
• Termination style (Wire Wrap)
• Panel cutout and bushing dimensions (Circular 6.35mm Dia, 1/4-40 thread)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (100,000 Cycles)

The C&K 7101P3DW4RE maintains full electrical and mechanical compatibility with the original part while offering active product status and improved compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7101P3DW4RE is the direct equivalent for the obsolete 7101P3DW4LE. Both parts share identical electrical ratings, mechanical dimensions, and functional specifications. The primary distinction is product status: the 7101P3DW4RE is actively manufactured and supported, whereas the 7101P3DW4LE is obsolete.

The 7101P3DW4RE maintains RoHS compliance and carries REACH Affected status, indicating current regulatory alignment. Both parts are classified as MSL 1 (Unlimited moisture sensitivity level), suitable for standard storage and handling conditions. The ECCN classification (EAR99) and HTSUS code (8536.50.9065) remain consistent, supporting seamless procurement and logistics integration.

Frequently Asked Questions (FAQ)

Q: Can the 7101P3DW4RE directly replace the 7101P3DW4LE in existing designs?

A: Yes. The 7101P3DW4RE is mechanically and electrically identical to the 7101P3DW4LE. Panel cutout dimensions, bushing thread specifications, actuator geometry, and electrical ratings are unchanged. No design modifications are required.

Q: What is the difference between ROHS3 and RoHS compliance?

A: Both designations indicate RoHS compliance. ROHS3 refers to the third iteration of RoHS certification. The 7101P3DW4RE carries current RoHS certification, confirming compliance with hazardous substance restrictions.

Q: Are there any differences in termination or packaging between these parts?

A: Both parts use wire wrap termination and share identical panel mount specifications. No packaging or termination differences exist that would affect installation or circuit integration.

Q: Why is the 7101P3DW4LE classified as obsolete?

A: Obsolescence reflects manufacturer discontinuation. The 7101P3DW4RE represents the active production equivalent, ensuring continued availability and manufacturer support.

Q: What is the significance of REACH Affected status on the 7101P3DW4RE?

A: REACH Affected indicates the part is subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. This is standard for components manufactured or distributed within the European Union and reflects current regulatory compliance.
