Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR19AS/UCV is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-Mom)
• Current rating (15A AC/DC)
• Voltage ratings (125V AC, 30V DC)
• Mounting type (Panel Mount, Snap-In)
• Termination style (Solder Lug)
• Actuator type and color (Concave, Black)
• Panel cutout dimensions (34.20mm x 17.20mm)
• Ingress protection rating (IP67)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life specifications
• Approval agencies (EN, UL)

The WR19AS/CUL meets all these criteria and qualifies as a direct substitute. The primary distinction is product status: WR19AS/UCV is obsolete, while WR19AS/CUL is active and RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

The WR19AS/CUL is the recommended selection for new designs and replacement applications due to its active product status and RoHS3 compliance certification. Inventory availability of 977 units for the WR19AS/CUL supports procurement for production and maintenance requirements.

Frequently Asked Questions (FAQ)

Q: Can WR19AS/CUL be used as a direct replacement for WR19AS/UCV in existing applications?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including circuit configuration, current and voltage ratings, mounting dimensions, and ingress protection rating. Panel cutout dimensions are identical at 34.20mm x 17.20mm, ensuring mechanical compatibility.

Q: What is the difference between WR19AS/UCV and WR19AS/CUL?

A: The primary difference is product status. WR19AS/UCV is obsolete, while WR19AS/CUL is active. Additionally, WR19AS/CUL carries RoHS3 compliance certification. All electrical and mechanical specifications remain identical.

Q: Are there any compliance or certification differences?

A: Both parts carry EN and UL approvals. WR19AS/CUL includes RoHS3 compliance, which is relevant for applications subject to RoHS regulations. WR19AS/UCV does not specify RoHS status.

Q: What are the critical parameters for substitution compatibility?

A: Substitution requires matching SPDT circuit configuration, 15A current rating at 125V AC/30V DC, panel mount snap-in mounting, solder lug termination, 34.20mm x 17.20mm panel cutout dimensions, IP67 ingress protection, and -25°C to 85°C operating temperature range.

Q: Is the panel cutout dimension critical for installation?

A: Yes. The rectangular panel cutout dimension of 34.20mm x 17.20mm is a fixed mechanical requirement for snap-in installation. Any substitute part must match this specification exactly to ensure proper panel mounting.
