Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UB5C-62RF1 is determined by strict equivalence across the following critical parameters:

• Resistance value: 62 Ohms
• Tolerance: ±1%
• Power rating: 5W
• Composition: Wirewound
• Package: Axial through-hole
• Temperature coefficient: ±20ppm/°C
• RoHS compliance: ROHS3 Compliant

The substitute part 45F62RE meets all electrical specifications and maintains mechanical compatibility through the axial package format. Both parts are active products with equivalent regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the UB5C-62RF1 and 45F62RE are active products with ROHS3 compliance and equivalent electrical performance. Selection between these parts should be based on:

• Physical space constraints: The UB5C-62RF1 has a smaller footprint (6.40mm x 12.70mm) compared to the 45F62RE (8.70mm x 23.80mm). Applications with limited board space may require the Riedon part.
• Inventory availability: The UB5C-62RF1 has 790 units in stock; the 45F62RE has 764 units in stock.
• Regulatory compliance: Both parts meet ROHS3 requirements and are suitable for applications requiring environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can the 45F62RE replace the UB5C-62RF1 in all applications?

A: The 45F62RE is electrically equivalent with matching resistance, tolerance, power rating, and temperature coefficient. However, the physical dimensions differ significantly. The 45F62RE is larger (8.70mm x 23.80mm versus 6.40mm x 12.70mm), which may affect board layout compatibility. Verify PCB footprint and clearance requirements before substitution.

Q: Are there any differences in operating temperature range?

A: The UB5C-62RF1 specifies an operating temperature range of -55°C to 250°C. The 45F62RE does not provide an operating temperature specification in the available data. For applications requiring confirmed temperature performance across the full -55°C to 250°C range, the UB5C-62RF1 is the specified choice.

Q: Do both parts have the same moisture sensitivity?

A: The UB5C-62RF1 has a Moisture Sensitivity Level (MSL) of 1 (Unlimited). The 45F62RE is listed as Not Applicable for MSL. Both parts are suitable for standard storage and handling conditions.

Q: What is the difference between the UB and Ohmicone® 40 series?

A: These are different product series from different manufacturers. The UB series is from Riedon; the Ohmicone® 40 series is from Ohmite. Both series produce wirewound resistors with equivalent electrical specifications for this 62 Ohm 5W application.
