Key Parameters

Substitute Part Grouping Explanation

Substitution for the TCH35PR100J is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 mOhms (exact match required)
• Tolerance: ±5% (defines acceptable resistance range)
• Power rating: 35W (thermal dissipation capability)
• Package: TO-220-2 (mechanical and electrical interface)
• Composition: Thick film (performance characteristics)
• Temperature coefficient: ±700ppm/°C (temperature stability)
• Operating temperature range: -55°C to 175°C (environmental limits)
• Moisture resistance: Required feature

The TCH35PR100JE meets all these criteria and qualifies as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The TCH35PR100JE is the direct equivalent substitute for the obsolete TCH35PR100J. Both components share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: the TCH35PR100JE is currently in active production and meets ROHS3 compliance requirements, whereas the original part is obsolete and RoHS non-compliant. For new designs and ongoing procurement, the TCH35PR100JE is the appropriate selection. Both parts carry the same ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can TCH35PR100JE be used as a direct replacement for TCH35PR100J?

A: Yes. The TCH35PR100JE is electrically and mechanically identical to the TCH35PR100J across all specified parameters, including resistance, tolerance, power rating, package type, and operating temperature range.

Q: What is the difference between TCH35PR100J and TCH35PR100JE?

A: The primary differences are product status and compliance. The TCH35PR100J is obsolete and RoHS non-compliant, while the TCH35PR100JE is active production and ROHS3 compliant. All electrical and mechanical characteristics are identical.

Q: Are there any packaging differences between these parts?

A: The TCH35PR100J is supplied in standard packaging, while the TCH35PR100JE is supplied in tube packaging. Both use the TO-220-2 package with identical physical dimensions and termination configuration.

Q: What are the key parameters that define substitution for this resistor?

A: Substitution is determined by matching resistance value (100 mOhms), tolerance (±5%), power rating (35W), package type (TO-220-2), composition (thick film), temperature coefficient (±700ppm/°C), operating temperature range (-55°C to 175°C), and moisture resistance feature.

Q: Is the TCH35PR100JE suitable for applications originally designed for the TCH35PR100J?

A: Yes. The TCH35PR100JE meets all electrical and mechanical requirements of the original specification and is suitable for direct substitution in all applications.
