Substitute Part Grouping Explanation

Substitution eligibility for the HS50 47R F is determined by strict equivalence across the following critical parameters:

• Resistance value: 47 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 50W (exact match required)
• Composition: Wirewound (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Housing material: Aluminum (exact match required)
• Mounting configuration: Flanges with solder lugs (exact match required)
• Package classification: Axial, Box (exact match required)

The identified substitute part HS50 47R F (ARCOL manufacturer) meets all electrical and mechanical parameters. Dimensional variations in width (1.102" vs 0.559") do not affect functional substitution when mounting space permits the larger footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite HS50 47R F and ARCOL HS50 47R F maintain Active product status and satisfy RoHS compliance requirements. The ARCOL variant includes documented pulse withstanding capability and carries MSL rating of 1 (Unlimited), indicating superior moisture resistance characteristics. Selection between these equivalents should be based on supply chain availability, as both components satisfy identical electrical specifications and mechanical mounting requirements. The width differential (1.102" vs 0.559") requires verification against available PCB or chassis mounting space in the target application.

Frequently Asked Questions (FAQ)

Q: Can the ARCOL HS50 47R F directly replace the Ohmite HS50 47R F?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters: 47 Ohms ±1%, 50W power rating, wirewound composition, ±100ppm/°C temperature coefficient, aluminum housing with flanged solder lug termination, and identical axial box packaging. The width dimension difference does not affect electrical function and requires only mechanical clearance verification.

Q: What are the critical parameters that must match for substitution?

A: Resistance (47 Ohms), tolerance (±1%), power rating (50W), composition (wirewound), temperature coefficient (±100ppm/°C), housing material (aluminum), mounting style (flanges with solder lugs), and package type (axial, box) must all match exactly.

Q: Are there compliance differences between the two parts?

A: Both parts comply with RoHS standards and carry EAR99 ECCN classification. The ARCOL variant specifies RoHS Compliant status with MSL 1 (Unlimited) and documented pulse withstanding capability, while the Ohmite variant specifies ROHS3 Compliant status.

Q: Does the dimensional difference affect circuit performance?

A: No. The width variation (1.102" vs 0.559") is a physical dimension only and does not alter electrical characteristics. Mounting space availability in the target application must be confirmed before selection.

Q: What is the inventory status for these parts?

A: Ohmite HS50 47R F: 1120 units in stock. ARCOL HS50 47R F: 1094 units in stock.
