Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR11AFN/V is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST only
• Current Rating: 15A (AC/DC)
• Voltage Ratings: 125V AC and 30V DC minimum
• Mounting Type: Panel Mount, Snap-In
• Panel Cutout Dimensions: Rectangular - 34.20mm x 17.20mm
• Termination Style: Quick Connect - 0.250" (6.3mm)
• Ingress Protection: IP67 minimum
• Operating Temperature Range: -25°C to 85°C minimum
• Mechanical Life: 30,000 Cycles minimum
• Electrical Life: 15,000 Cycles minimum

The WR11AFN (without the /V suffix designation) qualifies as a direct substitute, as it maintains identical electrical specifications, mechanical dimensions, and performance characteristics while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The WR11AFN is the appropriate substitute for the obsolete WR11AFN/V. Both parts share identical electrical and mechanical specifications, ensuring direct functional compatibility in existing applications. The WR11AFN offers the additional advantage of active product status, ensuring continued availability and supply chain reliability.

The WR11AFN carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and system updates. Both parts maintain EN and UL approvals, confirming compliance with international safety standards.

Selection between these parts should be based on application timeline and regulatory requirements. For new designs or systems requiring current compliance certifications, the WR11AFN is the preferred choice. For legacy system maintenance where the original part specification must be preserved, the WR11AFN provides functional equivalence with improved compliance status.

Frequently Asked Questions (FAQ)

Q: Can WR11AFN replace WR11AFN/V in existing applications?

A: Yes. The WR11AFN is a direct functional equivalent. Both parts share identical current ratings (15A AC/DC), voltage ratings (125V AC, 30V DC), panel cutout dimensions (34.20mm x 17.20mm), termination style (Quick Connect 0.250"), and ingress protection (IP67). Mechanical and electrical life specifications are identical at 30,000 and 15,000 cycles respectively.

Q: What is the difference between WR11AFN/V and WR11AFN?

A: The primary difference is product status. WR11AFN/V is obsolete, while WR11AFN is active. The WR11AFN also carries ROHS3 compliance and REACH unaffected certification, whereas the WR11AFN/V does not specify these compliance statuses. All electrical and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: The WR11AFN/V is specified with "-" packaging designation, while WR11AFN is supplied in bulk packaging. This reflects the difference in product status and availability. Functional specifications remain unchanged.

Q: What are the critical substitution parameters for this switch family?

A: Substitution requires matching on: SPST circuit configuration, 15A current rating, 125V AC and 30V DC voltage ratings, panel mount snap-in mounting, 34.20mm x 17.20mm panel cutout dimensions, Quick Connect 0.250" termination, IP67 ingress protection, and -25°C to 85°C operating temperature range.

Q: Are both parts approved for the same applications?

A: Yes. Both WR11AFN/V and WR11AFN carry EN and UL approvals. The WR11AFN additionally meets ROHS3 and REACH requirements, making it suitable for applications with current regulatory compliance mandates.
