UB3C-62RF8 Equivalent & Substitute Parts

Part Overview

The UB3C-62RF8 is a 62 Ohm ±1% 3W axial wirewound resistor manufactured by Riedon. This through-hole component is designed for current sensing applications and features flame-proof, moisture-resistant, and pulse-withstanding characteristics. The part is currently active in production with 973 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter set.

Substitute Part Grouping Explanation

The 43F62RE from Ohmite qualifies as a substitute for the UB3C-62RF8 based on the following critical parameters:

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

Both parts meet the electrical and mechanical requirements for direct substitution in applications requiring a 62 Ohm 3W axial wirewound resistor with ±1% tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both the UB3C-62RF8 and 43F62RE are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Physical space constraints: The UB3C-62RF8 has a smaller diameter (4.00mm vs 5.60mm) and shorter length (8.90mm vs 15.10mm), making it suitable for compact layouts.
• Packaging requirements: The UB3C-62RF8 is supplied in Tape & Reel format, while the 43F62RE is supplied in Bulk format.
• Inventory availability: Both parts maintain active stock levels.

Frequently Asked Questions (FAQ)

Q: Can the 43F62RE directly replace the UB3C-62RF8 in all applications?

A: Yes, the 43F62RE meets all critical electrical parameters (62 Ohms, ±1%, 3W, ±20ppm/°C) and composition requirements (wirewound, axial package). However, physical dimensions differ; verify that the larger size (5.60mm diameter, 15.10mm length) fits within your PCB layout constraints.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is determined by matching resistance value, tolerance, power rating, composition type, package configuration, temperature coefficient, and compliance certifications. All these parameters are identical between the UB3C-62RF8 and 43F62RE.

Q: Does packaging format affect electrical performance?

A: No. The difference between Tape & Reel and Bulk packaging is logistical only and does not affect component electrical or mechanical characteristics.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.
