Key Parameters

Substitute Part Grouping Explanation

The TMC005100R0FE02 manufactured by Vishay Dale qualifies as a direct substitute for the UAL5-100RF8 based on the following critical parameters:

• Identical resistance value: 100 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 7.5W
• Same composition: Wirewound
• Identical temperature coefficient: ±20ppm/°C
• Matching housing type: Aluminum
• Identical mounting feature: Flanges
• Matching lead style: Solder Lugs
• Same package configuration: Axial, Box
• Equivalent RoHS compliance: ROHS3 Compliant

Physical dimensions are within acceptable manufacturing tolerances. Both parts are Active status products with established supply chains.

Parameter Comparison

Engineering Selection Recommendations

Both the UAL5-100RF8 and TMC005100R0FE02 are Active status products with ROHS3 compliance and equivalent electrical specifications. The primary consideration is the operating temperature range: the UAL5-100RF8 supports -55°C ~ 275°C, while the TMC005100R0FE02 supports -55°C ~ 250°C. For applications operating above 250°C, the UAL5-100RF8 is the required selection. For applications within the -55°C ~ 250°C range, either part is functionally equivalent. Physical dimensions are within standard manufacturing tolerances for this component class.

Frequently Asked Questions (FAQ)

Q: Can TMC005100R0FE02 replace UAL5-100RF8 in all applications?

A: The TMC005100R0FE02 is suitable for applications operating within -55°C ~ 250°C. Applications requiring operation above 250°C must use the UAL5-100RF8.

Q: Are the physical dimensions identical?

A: Dimensions are within standard manufacturing tolerances. Length differs by 0.002" (0.04mm), width by 0.001" (0.01mm), and height by 0.001" (0.01mm). These variations are acceptable for standard PCB and chassis mount applications.

Q: Do both parts have identical electrical characteristics?

A: Yes. Resistance, tolerance, power rating, temperature coefficient, and composition are identical across both parts.

Q: What is the difference in RoHS compliance status?

A: Both parts are ROHS3 Compliant. No compliance difference exists between the two options.

Q: Are solder lug connections compatible between both parts?

A: Yes. Both parts use identical solder lug lead styles and are compatible with equivalent mounting hardware and PCB layouts.
