Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR19AF/UCV is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Current rating (15A AC/DC)
• Voltage ratings (125V AC, 30V DC)
• Mounting type (Panel Mount, Snap-In)
• Actuator type (Concave/Curved)
• Termination style (Quick Connect - 0.250")
• Panel cutout dimensions (Rectangular - 34.20mm x 17.20mm)
• Ingress protection rating (IP67)
• Operating temperature range (-25°C ~ 85°C)
• Mechanical and electrical life specifications

The WR19AF/CUL meets all these criteria and qualifies as a direct substitute. The primary distinction is product status: WR19AF/UCV is obsolete, while WR19AF/CUL is active production, with enhanced compliance documentation (RoHS3 Compliant, REACH Unaffected).

Parameter Comparison

Engineering Selection Recommendations

The WR19AF/CUL is the appropriate substitute for the obsolete WR19AF/UCV. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in existing applications. The WR19AF/CUL offers the advantage of active production status, ensuring long-term availability and supply chain continuity.

The WR19AF/CUL carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Both parts maintain EN and UL approvals, confirming compliance with international safety standards.

Frequently Asked Questions (FAQ)

Q: Can WR19AF/CUL be used as a direct replacement for WR19AF/UCV?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including circuit configuration, current and voltage ratings, mounting dimensions, and termination style. The WR19AF/CUL is the active production equivalent.

Q: What is the difference between WR19AF/UCV and WR19AF/CUL?

A: The primary difference is product status. WR19AF/UCV is obsolete, while WR19AF/CUL is in active production. The WR19AF/CUL additionally carries RoHS3 compliance and REACH unaffected certification. All electrical and mechanical parameters are identical.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts require a rectangular panel cutout of 34.20mm x 17.20mm and use identical snap-in mounting mechanisms.

Q: What termination style do these switches use?

A: Both parts use Quick Connect termination with 0.250" (6.3mm) spade connectors, enabling direct connection to standard quick-disconnect terminals.

Q: What is the ingress protection rating?

A: Both parts are rated IP67, providing dust-tight and waterproof protection suitable for harsh environmental applications.

Q: Are there packaging differences between the two parts?

A: WR19AF/UCV packaging is listed as dash (unspecified), while WR19AF/CUL is supplied in bulk packaging. This does not affect functional compatibility.
