Key Parameters

Substitute Part Grouping Explanation

The UB5C-330RF1 qualifies as a direct substitute for the UB5C-330RF8 based on identical electrical and mechanical parameters. Both parts share the same resistance value (330 Ohms), tolerance (±1%), power rating (5W), composition (wirewound), package type (axial), temperature coefficient (±20ppm/°C), operating temperature range (-55°C to 250°C), physical dimensions (0.250" Dia x 0.500" L), and feature set (current sense, flame proof, moisture resistant, pulse withstanding, safety).

The sole difference between these parts is packaging format: UB5C-330RF8 is supplied in Tape & Reel (TR) format, while UB5C-330RF1 is supplied in Bulk format. This distinction affects procurement and handling procedures but does not alter component performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both UB5C-330RF8 and UB5C-330RF1 are Active products manufactured by Riedon and maintain identical ROHS3 compliance and REACH unaffected status. Selection between these parts depends on procurement requirements and assembly processes. The Tape & Reel format (UB5C-330RF8) is suitable for automated pick-and-place assembly operations. The Bulk format (UB5C-330RF1) accommodates manual assembly workflows or applications where tape packaging is not required. Higher inventory availability of the UB5C-330RF1 (1665 units) may provide supply chain advantages for high-volume production runs.

Frequently Asked Questions (FAQ)

Q: Can UB5C-330RF1 replace UB5C-330RF8 in circuit applications? A: Yes. Both parts are electrically and mechanically identical. The UB5C-330RF1 functions identically in all circuit configurations where the UB5C-330RF8 is specified.

Q: What is the difference between Tape & Reel and Bulk packaging? A: Tape & Reel packaging supplies components on continuous carrier tape suitable for automated assembly equipment.
