Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR13ASN/UCV is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPDT
• Switch function: On-Off-On
• Current rating: 15A (AC/DC)
• Voltage rating: 125V AC / 30V DC
• Mounting type: Panel Mount, Snap-In
• Termination style: Solder Lug
• Panel cutout dimensions: Rectangular - 34.20mm x 17.20mm
• Ingress protection: IP67
• Operating temperature range: -25°C ~ 85°C
• Mechanical life: 30,000 Cycles
• Electrical life: 10,000 Cycles
• Approval agencies: EN, UL

Parts meeting all these parameters are classified as direct substitutes. Variations in product status, compliance certifications, or inventory availability do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

The WR13ASN/CUL is a direct functional equivalent to the WR13ASN/UCV. Both parts share identical electrical and mechanical specifications, including circuit configuration, current and voltage ratings, mounting dimensions, and environmental protection ratings.

The primary distinction is product status: WR13ASN/UCV is obsolete, while WR13ASN/CUL is active. The substitute part carries ROHS3 compliance certification, which may be required for new designs or systems subject to regulatory compliance mandates.

For applications requiring the WR13ASN/UCV, the WR13ASN/CUL provides full functional compatibility with the added benefit of current product availability and modern compliance certifications.
