Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UB3C-470RF8 is determined by the following critical parameters: resistance value (470 Ohms), tolerance (±1%), power rating (3W), composition (wirewound), and package type (axial). All substitute parts must match these core electrical specifications. Temperature coefficient (±20ppm/°C) and moisture sensitivity level (MSL 1) are maintained across all qualified substitutes. Operating temperature range may vary within acceptable limits for the application. RoHS compliance status is verified for each substitute to ensure regulatory alignment.

The following parts meet these substitution criteria:

43F470E (Ohmite, Series 40) RS02B470R0FE70 (Vishay Dale, Series RS)

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and meet RoHS compliance requirements. The UB3C-470RF8 and RS02B470R0FE70 are both ROHS3 Compliant, while the 43F470E carries standard RoHS Compliance. The UB3C-470RF8 and RS02B470R0FE70 share identical REACH status (REACH Unaffected), providing regulatory consistency. All parts are classified under ECCN EAR99 for export control purposes.

Selection between these substitutes should account for physical dimensions, as the UB3C-470RF8 is the most compact option (4.00mm diameter), while the 43F470E is the largest (5.60mm diameter). The RS02B470R0FE70 offers an intermediate size profile. Operating temperature range extends to 275°C for the 43F470E, providing additional thermal margin compared to the other options. Packaging format differs: UB3C-470RF8 is supplied in Tape & Reel, 43F470E in Bulk, and RS02B470R0FE70 in Cut Tape.

Frequently Asked Questions (FAQ)

Q: Can the 43F470E replace the UB3C-470RF8 in all applications? A: The 43F470E matches all critical electrical parameters (470 Ohms, ±1%, 3W, wirewound, ±20ppm/°C). Physical dimensions differ; verify PCB layout accommodates the larger 5.60mm diameter before substitution.

Q: What is the difference in operating temperature ranges? A: The UB3C-470RF8 operates from -55°C to 250°C, the 43F470E from -55°C to 275°C, and the RS02B470R0FE70 from -65°C to 250°C. Select based on your application's thermal requirements.

Q: Are there packaging differences between these parts? A: Yes. The UB3C-470RF8 is supplied in Tape & Reel format, the 43F470E in Bulk, and the RS02B470R0FE70 in Cut Tape. Packaging choice affects handling, storage, and assembly processes.

Q: Do all substitutes have the same moisture sensitivity rating? A: The UB3C-470RF8 and 43F470E both have MSL 1 (Unlimited). The RS02B470R0FE70 has MSL Not Applicable, indicating no moisture sensitivity constraints.

Q: Which substitute offers the best size compatibility with the original part? A: The RS02B470R0FE70 (4.75mm diameter) is closest in size to the UB3C-470RF8 (4.00mm diameter), minimizing potential PCB layout modifications.
