Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AHA50AJB-0R75 is determined by the following critical parameters:

• Resistance value: 750 mOhms (exact match required)
• Power rating: 50W (exact match required)
• Composition: Wirewound (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 250°C (exact match required)
• Housing type: Aluminum (exact match required)
• Mounting feature: Flanges (exact match required)
• Lead style: Solder Lugs (exact match required)
• Package type: Axial, Box (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The AHA50AFB-0R75 qualifies as a parametric equivalent. While tolerance specification differs (±1% versus ±5%), all other electrical and mechanical parameters remain identical, permitting direct substitution in applications where tighter tolerance is acceptable or beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both the AHA50AJB-0R75 and AHA50AFB-0R75 maintain Active product status with full ROHS3 compliance. Selection between these parts depends on tolerance requirements within the circuit design specification.

The AHA50AJB-0R75 (±5% tolerance) is suitable for applications where standard tolerance performance meets design margins. The AHA50AFB-0R75 (±1% tolerance) provides enhanced precision for circuits requiring tighter resistance accuracy. Both parts share identical mechanical dimensions, thermal characteristics, and power handling capabilities, ensuring direct PCB compatibility and thermal management equivalence.
