Key Parameters

Substitute Part Grouping Explanation

Substitution of the UB5C-62RF8 with the 45F62RE is permissible based on the following matched electrical and mechanical parameters:

Resistance value and tolerance remain identical at 62 Ohms ±1%, ensuring equivalent current-limiting and voltage-dropping characteristics. Power rating equivalence at 5W maintains thermal performance requirements. Both components utilize wirewound composition with identical temperature coefficient specifications of ±20ppm/°C, providing equivalent frequency response and thermal stability. Axial package configuration is maintained across both parts, confirming mechanical compatibility with through-hole PCB layouts. Both parts achieve ROHS3 compliance and EAR99 ECCN classification, satisfying regulatory requirements. The substitute part 45F62RE is manufactured by Ohmite within the Ohmicone® 40 series and maintains Active product status.

Physical dimension differences exist: the UB5C-62RF8 measures 0.250" diameter × 0.500" length (6.40mm × 12.70mm), while the 45F62RE measures 0.343" diameter × 0.937" length (8.70mm × 23.80mm). These dimensional variations require verification of available PCB space and component placement constraints prior to substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the UB5C-62RF8 and 45F62RE satisfy identical electrical specifications for 62 Ohm ±1% 5W wirewound resistor applications. Component selection between these parts should be based on:

Packaging availability and lead time requirements. The UB5C-62RF8 is supplied in Tape & Reel format with 697 units in stock, while the 45F62RE is supplied in Bulk packaging with 764 units available.

Physical space constraints within the assembly. The UB5C-62RF8 occupies a smaller footprint (6.40mm × 12.70mm) compared to the 45F62RE (8.70mm × 23.80mm). PCB layout verification is required to confirm accommodation of the larger substitute component.

Both parts maintain Active product status and full regulatory compliance under ROHS3 and EAR99 classifications, confirming suitability for production applications.

Frequently Asked Questions (FAQ)

Q: Can the 45F62RE directly replace the UB5C-62RF8 in existing designs?

A: Electrical substitution is valid based on matched resistance, tolerance, power rating, and temperature coefficient specifications. Physical substitution requires confirmation that PCB layout accommodates the larger dimensions of the 45F62RE (8.70mm diameter × 23.80mm length versus 6.40mm × 12.70mm for the UB5C-62RF8).

Q: Are there differences in operating temperature ranges between these parts?

A: The UB5C-62RF8 specifies an operating range of -55°C to 250°C. The 45F62RE does not provide an operating temperature range specification in the available data. Applications requiring operation at temperature extremes should prioritize the UB5C-62RF8.

Q: Do both parts meet the same regulatory requirements?

A: Both components are ROHS3 compliant and classified under ECCN EAR99. Both carry identical HTSUS classification (8533.21.0080), confirming equivalent regulatory status for procurement and export purposes.

Q: What is the difference in packaging format?

A: The UB5C-62RF8 is supplied in Tape & Reel format suitable for automated assembly processes. The 45F62RE is supplied in Bulk packaging, which may require manual handling or reeling for automated placement equipment.

Q: Are moisture sensitivity levels equivalent?

A: The UB5C-62RF8 carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The 45F62RE is classified as Not Applicable for MSL, confirming equivalent moisture tolerance characteristics.
