Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UB5C-150RF1 is determined by strict equivalence across the following critical parameters:

• Resistance value: 150 Ohms
• Tolerance: ±1%
• Power rating: 5W
• Composition: Wirewound
• Package: Axial through-hole
• Temperature coefficient: ±20ppm/°C
• Number of terminations: 2

All identified substitute parts meet these core electrical and mechanical requirements. Physical dimensions may vary within acceptable assembly tolerances for axial components. Operating temperature ranges and feature sets are provided for reference but do not restrict substitution eligibility when the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three parts—UB5C-150RF1, 45F150E, and RS005150R0FE73—are active production components with equivalent electrical specifications. Selection should be based on the following factors:

UB5C-150RF1 (Riedon): Primary choice with ROHS3 compliance, REACH Unaffected status, and compact axial dimensions (6.40mm x 12.70mm). Includes current sense, flame proof, moisture resistant, pulse withstanding, and safety features. Operating range -55°C ~ 250°C.

45F150E (Ohmite): Alternative with RoHS compliance and extended operating temperature to 275°C. Larger physical dimensions (8.70mm x 23.80mm) may require PCB layout verification. REACH status vendor undefined.

RS005150R0FE73 (Vishay Dale): Alternative with ROHS3 compliance and REACH Unaffected status. Extended lower operating temperature limit (-65°C). Moisture resistant feature specified. Intermediate physical dimensions (7.92mm x 22.23mm). Cut Tape packaging available.

Frequently Asked Questions (FAQ)

Q: Can 45F150E replace UB5C-150RF1 in all applications? A: Yes, electrically equivalent. Physical dimensions differ (8.70mm x 23.80mm vs. 6.40mm x 12.70mm). Verify PCB layout accommodates larger size. REACH status is vendor undefined for 45F150E.

Q: What is the primary difference between these substitute parts? A: All three parts share identical electrical parameters (150Ω, ±1%, 5W, ±20ppm/°C). Differences exist in physical dimensions, operating temperature ranges, and regulatory compliance documentation. UB5C-150RF1 is the most compact.
