AHA500JB-100R Equivalent & Substitute Parts

Part Overview

The AHA500JB-100R is a 100 Ohms ±5% 5W wirewound chassis mount resistor manufactured by YAGEO in the AHA series. This component is an active product with full inventory availability (835 pcs in stock). The part features aluminum housing with flanged mounting, solder lug termination, and operates across -55°C to 250°C. Finding equivalent and substitute parts may be necessary for supply chain optimization, design flexibility, or when the original manufacturer part becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the AHA500JB-100R is determined by the following critical parameters:

Resistance Value: Must be 100 Ohms
Composition: Must be Wirewound
Housing Type: Must be Aluminum
Mounting Feature: Must include Flanges
Lead Style: Must be Solder Lugs
Package Type: Must be Axial, Box
Operating Temperature Range: Must support -55°C ~ 250°C minimum
RoHS Compliance: Must meet ROHS3 standard

The substitute parts identified (RH005100R0FE02 and TMC005100R0FE02) meet all mandatory substitution criteria. Both are Vishay Dale products in the RH and TMC series respectively, featuring identical resistance, composition, housing, mounting, and lead specifications. The substitutes offer enhanced performance characteristics including improved tolerance (±1% vs ±5%) and higher power rating (7.5W vs 5W), with superior temperature coefficient stability (±20ppm/°C vs ±200ppm/°C).

Engineering Selection Recommendations

Both RH005100R0FE02 and TMC005100R0FE02 are valid substitutes for the AHA500JB-100R based on compliance and product status criteria. All three parts maintain active product status and ROHS3 compliance. The substitute parts from Vishay Dale provide superior electrical performance with tighter tolerance (±1%) and higher power dissipation capability (7.5W), making them suitable for applications requiring enhanced precision and thermal headroom. Physical dimensions are comparable with minimal variation in height and width, supporting direct mechanical interchange in most chassis mount applications. Both substitutes are currently in stock with adequate inventory (846 pcs and 1053 pcs respectively).

Frequently Asked Questions (FAQ)

Q: Can RH005100R0FE02 or TMC005100R0FE02 be used as direct replacements for AHA500JB-100R?

A: Yes. Both substitute parts meet all mandatory substitution criteria including resistance value, wirewound composition, aluminum housing, flanged mounting, solder lug termination, and axial box packaging. Physical dimensions are compatible for chassis mount applications.

Q: What are the key differences between the main part and substitutes?

A: The primary differences are tolerance (±5% vs ±1%), power rating (5W vs 7.5W), and temperature coefficient (±200ppm/°C vs ±20ppm/°C). The substitutes offer improved electrical performance and thermal capacity.

Q: Are there any mechanical compatibility concerns?

A: Dimensions are comparable. The substitute parts are slightly smaller in height (0.335" vs 0.358") and marginally different in length and width. These variations are within typical mechanical tolerances for flanged chassis mount resistors and do not prevent direct substitution.

Q: Do all parts meet the same compliance standards?

A: Yes. The AHA500JB-100R, RH005100R0FE02, and TMC005100R0FE02 are all ROHS3 compliant and maintain active product status with current manufacturer support.

Q: What is the difference between RH005100R0FE02 and TMC005100R0FE02?

A: Both parts are manufactured by Vishay Dale with identical electrical specifications and physical dimensions. They differ only in series designation (RH vs TMC) and REACH status documentation. Electrical and mechanical performance are equivalent.

Q: Can the 5W rating of the main part be directly replaced with the 7.5W rating of the substitutes?

A: Yes. The higher power rating of the substitute parts provides additional thermal margin and does not create compatibility issues. Applications designed for 5W operation will function within the thermal envelope of 7.5W-rated components.
