Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAH20PR100J is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 mOhms
• Tolerance: ±5%
• Power rating: 20W
• Package type: TO-220-2
• Composition: Thick Film
• Mechanical dimensions: 0.410" L x 0.125" W, 0.650" max height
• Termination count: 2
• Feature set: Moisture Resistant, Pulse Withstanding

The TAH20PR100JE meets all these criteria and is classified as a direct manufacturer equivalent from Ohmite's TAH series.

Parameter Comparison

Engineering Selection Recommendations

The TAH20PR100JE is the direct equivalent substitute for the obsolete TAH20PR100J. Both parts are manufactured by Ohmite and share identical electrical and mechanical specifications across all critical parameters: 100 mOhms resistance, ±5% tolerance, 20W power rating, TO-220-2 package, and feature set.

The primary distinction is product status: the TAH20PR100J is obsolete while the TAH20PR100JE is active and currently in production. Additionally, the TAH20PR100JE achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. For new designs or system refreshes, the TAH20PR100JE is the appropriate selection. For legacy system maintenance requiring exact historical equivalence, the TAH20PR100J remains functionally identical in all electrical and mechanical aspects.

Frequently Asked Questions (FAQ)

Q: Can the TAH20PR100JE be used as a direct replacement for the TAH20PR100J?

A: Yes. The TAH20PR100JE is electrically and mechanically identical to the TAH20PR100J across all specified parameters: resistance, tolerance, power rating, package type, dimensions, and feature set. Both are TO-220-2 through-hole components with identical pinout and mounting requirements.

Q: What is the difference between these two parts?

A: The TAH20PR100J is obsolete, while the TAH20PR100JE is active. The TAH20PR100JE also achieves ROHS3 compliance. No electrical or mechanical differences exist between the parts.

Q: Are there any packaging considerations when substituting?

A: The TAH20PR100J was supplied in standard packaging, while the TAH20PR100JE is supplied in tube packaging. Both are through-hole components with identical physical dimensions and mounting footprints, so no PCB or assembly modifications are required.

Q: Will the TAH20PR100JE work in circuits designed for the TAH20PR100J?

A: Yes. The parts are functionally equivalent with identical electrical characteristics and physical form factor. No circuit modifications or re-qualification is necessary for substitution.
