Key Parameters

Substitute Part Grouping Explanation

The UAL10-2RF8 qualifies as a direct substitute for the AHA10AFB-2R based on the following critical parameters:

• Identical resistance value: 2 Ohms
• Identical tolerance: ±1%
• Identical power rating: 10W
• Identical composition: Wirewound
• Identical mounting feature: Flanges with solder lugs
• Identical package type: Axial, Box
• Identical RoHS compliance: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)
• Identical REACH status: REACH Unaffected

The UAL10-2RF8 maintains full electrical and mechanical compatibility with the AHA10AFB-2R within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the AHA10AFB-2R and UAL10-2RF8 are active production components with full ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. The UAL10-2RF8 offers enhanced thermal stability with a lower temperature coefficient (±50ppm/°C versus ±200ppm/°C) and an extended upper operating temperature limit of 275°C compared to 250°C. Physical dimensions are within 0.5% variance, and both components utilize identical solder lug termination and flange mounting configurations. Selection between these parts should be based on inventory availability and specific thermal performance requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can the UAL10-2RF8 directly replace the AHA10AFB-2R in existing designs?

A: Yes. Both components share identical electrical specifications (2 Ohms, ±1%, 10W), composition (wirewound), and mechanical mounting features (flanges with solder lugs). Physical dimensions vary by less than 0.5%, and both are ROHS3 compliant with unlimited MSL ratings.

Q: What is the difference in temperature coefficient between these parts?

A: The AHA10AFB-2R has a temperature coefficient of ±200ppm/°C, while the UAL10-2RF8 has ±50ppm/°C. The UAL10-2RF8 provides superior temperature stability, resulting in more consistent resistance values across the operating temperature range.

Q: Are there any dimensional constraints I should consider?

A: The UAL10-2RF8 is slightly larger in length and width (0.752" x 0.799" versus 0.748" x 0.787") but has a lower seated height (0.417" versus 0.429"). Verify clearance in your PCB layout and chassis mounting configuration.

Q: Do both parts meet regulatory requirements?

A: Yes. Both the AHA10AFB-2R and UAL10-2RF8 are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification with identical HTSUS codes (8533.21.0080).

Q: What is the operating temperature range for each part?

A: The AHA10AFB-2R operates from -55°C to 250°C. The UAL10-2RF8 extends the upper limit to 275°C, providing additional thermal margin for high-temperature applications.
