Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UB5C-200RF1 is determined by strict equivalence across the following critical parameters:

• Resistance value: 200 Ohms
• Tolerance: ±1%
• Power rating: 5W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±20ppm/°C
• Regulatory compliance: ROHS3 Compliant and REACH Unaffected status

The substitute part 45F200E meets all specified electrical and mechanical requirements. Both components share identical resistance, tolerance, power rating, composition, and temperature coefficient specifications. Package type remains axial with two terminations. Regulatory compliance aligns across both ROHS3 and REACH classifications.

Parameter Comparison

Engineering Selection Recommendations

Both the UB5C-200RF1 and 45F200E maintain Active product status with full regulatory compliance. Selection between these components should be based on:

• Physical space constraints: The UB5C-200RF1 features a smaller form factor (6.40mm x 12.70mm) compared to the 45F200E (8.70mm x 23.80mm). Applications with restricted board real estate may require the Riedon component.
• Inventory availability: The 45F200E currently maintains higher stock levels (1007 units) versus the UB5C-200RF1 (709 units).
• Electrical performance: Both components deliver identical electrical specifications across resistance, tolerance, power rating, and temperature coefficient parameters.
• Regulatory requirements: Both parts satisfy ROHS3 and REACH compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 45F200E directly replace the UB5C-200RF1 in existing designs?

A: Direct electrical replacement is supported. Both components share identical resistance (200 Ohms), tolerance (±1%), power rating (5W), and temperature coefficient (±20ppm/°C) specifications. Physical dimensions differ; verify PCB layout accommodates the larger 45F200E form factor (8.70mm x 23.80mm versus 6.40mm x 12.70mm).

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

A: The UB5C-200RF1 specifies an operating range of -55°C to 250°C. The 45F200E does not provide an operating temperature range in the available specifications. Both components maintain identical temperature coefficient performance at ±20ppm/°C.

Q: Do both parts meet the same regulatory standards?

A: Both the UB5C-200RF1 and 45F200E are ROHS3 Compliant and REACH Unaffected, satisfying equivalent regulatory requirements.

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

A: Physical dimensions represent the primary selection criterion. The UB5C-200RF1 occupies less board space, while the 45F200E offers higher current inventory availability. Electrical performance remains equivalent across all specified parameters.
