UB5C-200RF8 Equivalent & Substitute Parts

Part Overview

The UB5C-200RF8 is a 200 Ohm, ±1% tolerance, 5W axial wirewound resistor manufactured by Riedon. This component is designed for through-hole applications requiring current sensing functionality with enhanced reliability features including flame proof, moisture resistant, and pulse withstanding characteristics. The part is Active in product status and maintains full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UB5C-200RF8 is determined by strict equivalence in the following parameters:

• Resistance value: 200 Ohms
• Tolerance: ±1%
• Power rating: 5W
• Composition: Wirewound
• Package: Axial configuration
• Temperature coefficient: ±20ppm/°C
• Termination count: 2

The substitute part 45F200E meets all electrical specifications and mechanical requirements. Both parts are Active products with ROHS3 compliance and REACH Unaffected status. Physical dimensions differ between the main part (0.250" Dia x 0.500" L) and the substitute (0.343" Dia x 0.937" L), which may affect board layout considerations but does not impact electrical equivalence for the specified application.

Parameter Comparison

Engineering Selection Recommendations

Both the UB5C-200RF8 and 45F200E are Active products meeting identical electrical specifications for 200 Ohm, ±1%, 5W wirewound axial resistors. Selection between these parts is based on:

• Availability and inventory status
• Physical space constraints on the printed circuit board, as the 45F200E has larger dimensions
• Packaging requirements (UB5C-200RF8 supplied in Tape & Reel; 45F200E supplied in Bulk)
• Compliance certifications, which are equivalent for both parts (ROHS3 Compliant, REACH Unaffected, EAR99 classification)

Both parts maintain the same temperature coefficient and operating temperature range specifications required for the application.

Frequently Asked Questions (FAQ)

Q: Can the 45F200E directly replace the UB5C-200RF8 in all applications?

A: Yes, from an electrical standpoint. Both parts have identical resistance, tolerance, power rating, temperature coefficient, and termination configuration. Physical dimensions differ; verify board layout accommodates the larger 45F200E package (0.343" Dia x 0.937" L versus 0.250" Dia x 0.500" L).

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

A: Resistance value (200 Ohms), tolerance (±1%), power rating (5W), composition (Wirewound), package type (Axial), temperature coefficient (±20ppm/°C), and termination count (2) must remain constant for substitution.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99. Moisture Sensitivity Level differs (UB5C-200RF8 is MSL 1; 45F200E is Not Applicable), but this does not affect electrical equivalence.

Q: What is the primary consideration when selecting between these substitute parts?

A: Physical dimensions and packaging format. The UB5C-200RF8 is supplied in Tape & Reel with smaller dimensions, while the 45F200E is supplied in Bulk with larger dimensions. Board layout and assembly process requirements should guide selection.
