Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: resistance value (500 mOhms), tolerance (±1%), power rating (10W), composition (wirewound), package type (axial), temperature coefficient (±90ppm/°C), and operating temperature range (-65°C to 250°C). Packaging format (Tape & Reel, Cut Tape, or Bulk) does not affect electrical or mechanical compatibility and represents a distribution variable only. All listed substitutes meet these core electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

RS010R5000FE73 (Vishay Dale, Cut Tape) is electrically and mechanically identical to the primary part RS010R5000FS73, with identical dimensions and all core electrical parameters. The primary distinction is packaging format (Cut Tape versus Tape & Reel) and RoHS compliance status (ROHS3 Compliant). Selection between these two Vishay Dale variants depends on packaging requirements and regulatory compliance mandates.

40FR50 (Ohmite, Bulk) meets all critical electrical specifications and operates within compatible temperature parameters. Physical dimensions are slightly larger (0.406" Dia x 1.902" L versus 0.375" Dia x 1.780" L). This part is suitable for applications where dimensional tolerance permits the increased size. Operating temperature range is not specified for this part.

Frequently Asked Questions (FAQ)

Q: Can RS010R5000FE73 be used as a direct replacement for RS010R5000FS73? A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications, tolerance, power rating, and physical dimensions. The difference is packaging format (Cut Tape versus Tape & Reel). Electrical and mechanical compatibility is complete.

Q: What is the primary difference between RS010R5000FS73 and RS010R5000FE73? A: The parts are electrically and mechanically identical. RS010R5000FS73 is supplied in Tape & Reel packaging, while RS010R5000FE73 is supplied in Cut Tape packaging. RS010R5000FE73 also carries ROHS3 compliance certification.

Q: Can 40FR50 replace RS010R5000FS73 in all applications? A: 40FR50 meets all core electrical requirements (500 mOhms, ±1%, 10W, wirewound, axial). Physical dimensions are larger (0.406" Dia x 1.902" L). Substitution is valid where board layout and mechanical constraints permit the increased size. Operating temperature range is not specified for 40FR50.

Q: Are there dimensional constraints when substituting with 40FR50? A: Yes. 40FR50 has a larger diameter (0.406" versus 0.375") and length (1.902" versus 1.780"). Verify that PCB layout, component spacing, and mechanical clearances accommodate these dimensions before selection.

Q: What packaging formats are available for these substitutes? A: RS010R5000FS73 is supplied in Tape & Reel format. RS010R5000FE73 is supplied in Cut Tape format. 40FR50 is supplied in Bulk format. Selection depends on assembly process requirements and order quantity.
