Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U23P3D9W4LE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-Off-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole)
• Actuator type and length (Flat Anti-Rotation, 13.21mm)
• Termination style (Wire Wrap)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)
• Base product number (U23P3D)

The substitute part U23P3D9W4RE matches all these parameters and belongs to the same C&K 7000 series family.

Parameter Comparison

Engineering Selection Recommendations

The U23P3D9W4RE is the direct substitute for the obsolete U23P3D9W4LE. Both parts share identical electrical and mechanical specifications within the C&K 7000 series family.

The primary distinction is product status: U23P3D9W4LE is obsolete, while U23P3D9W4RE is active and currently in production. The U23P3D9W4RE maintains full compatibility with existing designs and PCB layouts that specify the U23P3D9W4LE.

Regulatory compliance differs between the two parts. The U23P3D9W4LE carries ROHS3 compliance with REACH Unaffected status, while U23P3D9W4RE is RoHS Compliant with REACH Affected status. Both parts meet applicable environmental and regulatory requirements for their respective production periods.

Frequently Asked Questions (FAQ)

Q: Can U23P3D9W4RE directly replace U23P3D9W4LE in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: DPDT circuit, 5A rating at 120V AC and 28V DC, through-hole mounting, flat anti-rotation actuator at 13.21mm, wire wrap termination, and -30°C to 85°C operating range.

Q: Why is the U23P3D9W4LE listed as obsolete?

A: Product obsolescence reflects manufacturing discontinuation by C&K. The U23P3D9W4RE remains in active production and serves as the current equivalent for new designs and component replenishment.

Q: Are there differences in RoHS or REACH compliance between these parts?

A: Yes. The U23P3D9W4LE is ROHS3 Compliant and REACH Unaffected. The U23P3D9W4RE is RoHS Compliant and REACH Affected. Both certifications are valid for their respective production periods. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: What is the wire wrap termination style?

A: Wire wrap termination allows direct connection of wire leads without soldering, suitable for breadboard prototyping, test fixtures, and applications requiring tool-free assembly and disassembly.

Q: Are the actuator dimensions identical?

A: Yes. Both parts feature a flat anti-rotation actuator with 13.21mm length, ensuring identical panel cutout and mounting envelope compatibility.
