AHA50AFB-15R Equivalent & Substitute Parts

Part Overview

The AHA50AFB-15R is a 15 Ohms ±1% 50W wirewound chassis mount resistor manufactured by YAGEO. This component is designed for high-power applications requiring precision resistance with stable thermal performance across industrial temperature ranges. The part is currently in active production status with ROHS3 compliance and REACH unaffected certification, making it suitable for modern electronic assemblies requiring regulatory compliance.

Substitute parts become necessary when addressing supply chain constraints, lead time requirements, or specific application performance criteria within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AHA50AFB-15R is determined by the following mandatory parameters:

• Resistance value: 15 Ohms
• Tolerance: ±1%
• Power rating: 50W
• Composition: Wirewound
• Mounting feature: Flanges with solder lugs
• Housing type: Aluminum
• RoHS compliance: ROHS3 Compliant

All substitute parts listed meet these core electrical and mechanical requirements. Variations in temperature coefficient, maximum operating temperature, and physical dimensions remain within acceptable ranges for direct substitution in applications designed for the AHA50AFB-15R.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full regulatory compliance with ROHS3 and REACH requirements. Selection between the AHA50AFB-15R and its substitutes should be based on:

• Supply availability and lead time requirements
• Physical space constraints within the assembly, noting dimensional variations of ±0.77mm in length and ±0.40mm in width
• Temperature coefficient performance requirements, where substitute parts offer improved stability at ±20ppm/°C to ±30ppm/°C compared to the main part at ±200ppm/°C
• Extended operating temperature capability to 275°C available in all substitute options versus 250°C for the main part

All parts are electrically and mechanically interchangeable within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can the AHA50AFB-15R be directly replaced with any of the listed substitutes?

A: Yes. All substitute parts meet the core electrical specifications (15 Ohms ±1% at 50W) and mechanical requirements (wirewound, aluminum housing, flanged solder lugs). Physical dimensions vary by less than 1mm, and all parts maintain ROHS3 and REACH compliance.

Q: What is the significance of temperature coefficient differences?

A: Temperature coefficient indicates resistance value drift with temperature change. The AHA50AFB-15R has ±200ppm/°C, while substitutes range from ±20ppm/°C to ±30ppm/°C. Lower values indicate greater resistance stability across temperature variations. Applications requiring tighter resistance tolerance over temperature ranges benefit from substitute parts with lower temperature coefficients.

Q: Are there dimensional constraints for substitution?

A: Physical dimensions vary slightly across parts. The AHA50AFB-15R measures 50.00 x 29.00mm with 16.50mm seated height. Substitutes range from 49.23 to 50.00mm in length, 28.96 to 29.36mm in width, and 15.75 to 16.28mm in height. Verify available mounting space before selection.

Q: Do all parts support the same operating temperature range?

A: The AHA50AFB-15R operates from -55°C to 250°C. All substitute parts extend the upper limit to 275°C. Applications requiring operation above 250°C must use substitute parts.

Q: What packaging format is available for all parts?

A: All parts are supplied in bulk packaging with solder lugs for direct mounting to chassis or PCB terminals.
