Key Parameters

Substitute Part Grouping Explanation

Substitution for the WR13AT/UCV is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Current and voltage ratings (15A AC/DC, 125V AC, 30V DC)
• Mounting type and panel cutout dimensions (Panel Mount, Snap-In; 34.20mm x 17.20mm)
• Termination style (Screw Terminal)
• Ingress protection rating (IP67)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life specifications (30,000 cycles mechanical, 10,000 cycles electrical)

The WR13AT/CUL meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The WR13AT/CUL is the direct substitute for the obsolete WR13AT/UCV. Both parts share identical electrical specifications, mechanical dimensions, and functional characteristics. The WR13AT/CUL carries Active product status and includes ROHS3 compliance and REACH unaffected certification, making it suitable for new designs and replacement applications where regulatory compliance is required. Both parts maintain EN and UL approvals and are manufactured by NKK Switches within the same WR series.

Frequently Asked Questions (FAQ)

Q: Can the WR13AT/CUL directly replace the WR13AT/UCV in existing applications?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical circuit configuration (SPDT), current and voltage ratings (15A AC/DC, 125V AC, 30V DC), mounting type (Panel Mount, Snap-In), panel cutout dimensions (34.20mm x 17.20mm), termination style (Screw Terminal), and ingress protection rating (IP67). Physical installation and electrical connections are identical.

Q: What is the difference between WR13AT/UCV and WR13AT/CUL?

A: The primary difference is product status. The WR13AT/UCV is obsolete, while the WR13AT/CUL is active. The WR13AT/CUL includes ROHS3 compliance and REACH unaffected certification. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The WR13AT/UCV is supplied with unspecified packaging, while the WR13AT/CUL is supplied in bulk packaging. This does not affect functional compatibility.

Q: Do both parts meet the same regulatory approvals?

A: Yes. Both the WR13AT/UCV and WR13AT/CUL carry EN and UL approvals. The WR13AT/CUL additionally specifies ROHS3 compliance and REACH unaffected status.

Q: What are the mechanical and electrical life specifications?

A: Both parts are rated for 30,000 mechanical cycles and 10,000 electrical cycles, with an operating temperature range of -25°C to 85°C.
