Key Parameters

Substitute Part Grouping Explanation

Substitution of the TDH35PR100J is determined by strict equivalence across the following critical parameters:

• Resistance Value: 100 mOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 35W (exact match required)
• Package Configuration: TO-263-3 D2PAK with 2 leads plus tab (exact match required)
• Composition: Thick film construction (exact match required)
• Temperature Coefficient: ±700 ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 150°C (exact match required)

The TDH35PR100J has one direct substitute: TDH35PR100JE. This substitute maintains identical electrical and mechanical specifications while differing only in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TDH35PR100JE serves as the direct substitute for the obsolete TDH35PR100J. Both components are electrically and mechanically identical across all functional parameters. The primary distinction is product lifecycle status: the TDH35PR100J is obsolete while the TDH35PR100JE is active in production.

For new designs and ongoing procurement, the TDH35PR100JE is the appropriate selection. This substitute provides ROHS3 compliance, whereas the original part is RoHS non-compliant. Both components maintain identical electrical performance, thermal characteristics, and package dimensions, ensuring direct compatibility in existing circuit designs without modification to PCB layouts or thermal management strategies.

Frequently Asked Questions (FAQ)

Q: Can TDH35PR100JE be used as a direct replacement for TDH35PR100J?

A: Yes. The TDH35PR100JE is electrically and mechanically identical to the TDH35PR100J. All critical parameters including resistance value, tolerance, power rating, temperature coefficient, and package configuration are equivalent. Direct substitution is possible without circuit modification.

Q: What is the difference between these two parts?

A: The TDH35PR100J is obsolete, while TDH35PR100JE is active. The TDH35PR100JE also carries ROHS3 compliance, whereas the TDH35PR100J is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or footprint differences?

A: No. Both parts use the TO-263-3 D2PAK package with identical dimensions: 0.398" L x 0.378" W (10.10mm x 9.60mm) and maximum seated height of 0.185" (4.70mm). PCB footprints are interchangeable.

Q: What is the operating temperature range for these resistors?

A: Both the TDH35PR100J and TDH35PR100JE operate across -55°C to 150°C with a temperature coefficient of ±700 ppm/°C.

Q: Are moisture sensitivity considerations different between these parts?

A: No. Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage or assembly.
