Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UB3C-62RF1 is determined by strict equivalence across the following critical parameters:

• Resistance value: 62 Ohms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Package: Axial through-hole
• Temperature coefficient: ±20ppm/°C
• RoHS compliance: ROHS3 Compliant

The substitute part 43F62RE meets all mandatory electrical specifications. Physical dimensions vary between manufacturers due to different design approaches, but both components maintain axial package compatibility for through-hole PCB mounting. Compliance certifications (RoHS3, REACH Unaffected, EAR99) are equivalent across both parts.

Parameter Comparison

Engineering Selection Recommendations

Both the UB3C-62RF1 and 43F62RE are active production components with equivalent electrical performance. Selection between these parts should be based on:

• PCB layout constraints: The UB3C-62RF1 has a more compact axial profile (0.157" diameter × 0.350" length), while the 43F62RE is larger (0.220" diameter × 0.594" length). Verify available board space before substitution.
• Regulatory compliance: Both parts meet ROHS3, REACH, and EAR99 requirements.
• Inventory availability: UB3C-62RF1 has 840 units in stock; 43F62RE has 913 units in stock.
• Application-specific features: The UB3C-62RF1 includes documented current sense, flame proof, moisture resistant, and pulse withstanding characteristics. Confirm these features are not required for your application before substituting with 43F62RE.

Frequently Asked Questions (FAQ)

Q: Can 43F62RE be used as a direct replacement for UB3C-62RF1?

A: Yes, from an electrical standpoint. Both components have identical resistance (62 Ohms), tolerance (±1%), power rating (3W), temperature coefficient (±20ppm/°C), and wirewound composition. However, physical dimensions differ significantly. Verify PCB layout compatibility before substitution.

Q: What are the main physical differences between these parts?

A: The UB3C-62RF1 measures 0.157" diameter × 0.350" length, while the 43F62RE measures 0.220" diameter × 0.594" length. The 43F62RE is substantially larger in both dimensions. Confirm your PCB design accommodates the larger footprint.

Q: Are both parts RoHS compliant?

A: Yes. Both UB3C-62RF1 and 43F62RE are ROHS3 Compliant and REACH Unaffected, meeting current environmental regulations.

Q: Does the UB3C-62RF1 have special features that 43F62RE lacks?

A: The UB3C-62RF1 is documented with current sense, flame proof, moisture resistant, and pulse withstanding characteristics. The 43F62RE specification does not list these features. If your application requires these specific capabilities, the UB3C-62RF1 is the appropriate choice.

Q: What is the temperature operating range for both parts?

A: The UB3C-62RF1 operates from -55°C to 250°C. The 43F62RE operating temperature range is not specified in the provided data. Verify temperature requirements for your application.
