TNP10SA2R00FE Equivalent & Substitute Parts

Part Overview

The TNP10SA2R00FE is a through-hole resistor manufactured by Ohmite with a resistance value of 2 ohms and 1% tolerance, rated for 10W power dissipation in a TO-126 package. This component is classified as obsolete, making identification of suitable substitute parts necessary for ongoing design support and procurement continuity. The part maintains ROHS3 compliance and carries an MSL rating of 1 (unlimited moisture sensitivity level).

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TNP10SA2R00FE is based on the following critical parameters:

Electrical Equivalence Criteria:

• Resistance value: 2 ohms (exact match required)
• Power dissipation capability: minimum 10W
• Through-hole configuration for PCB mounting compatibility

Compliance & Certification Criteria:

• ROHS3 compliance maintained
• EAR99 ECCN classification
• Moisture sensitivity level compatibility

The substitute part TBH25P2R00JE meets the core electrical requirements with a 2-ohm resistance value and exceeds the power rating at 25W. While the tolerance specification differs (±5% versus ±1%), the substitute maintains through-hole mounting compatibility and full regulatory compliance. The TO-220 package provides equivalent lead configuration for standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The TBH25P2R00JE serves as a functional substitute for the obsolete TNP10SA2R00FE based on the following engineering criteria:

Electrical Compatibility: Both components provide 2-ohm resistance with through-hole mounting. The substitute's 25W power rating exceeds the original 10W specification, providing thermal margin in the application circuit.

Regulatory Compliance: Both parts maintain ROHS3 compliance and carry identical EAR99 export classification, ensuring no regulatory barriers to substitution.

Product Availability: The substitute is classified as active product status with documented inventory (836 pcs), whereas the original part is obsolete. This ensures long-term procurement viability and supply chain continuity.

Package Consideration: The TO-220 package of the substitute differs from the TO-126 package of the original part. PCB layout modifications may be required to accommodate the different package footprint and lead spacing. The substitute's maximum seated height of 0.630" (16.00mm) should be verified against available board clearance.

Tolerance Trade-off: The substitute tolerance of ±5% is wider than the original ±1%. Applications requiring strict tolerance control should evaluate whether this specification change affects circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the TBH25P2R00JE directly replace the TNP10SA2R00FE without PCB modifications?

A: Direct replacement without PCB modifications is not possible due to package differences. The TNP10SA2R00FE uses TO-126 packaging while the TBH25P2R00JE uses TO-220 packaging. These packages have different lead spacing and footprints. PCB layout changes are required for mechanical mounting compatibility.

Q: Does the higher power rating of the substitute (25W vs 10W) create any compatibility issues?

A: No compatibility issues arise from the higher power rating. The 25W rating of the substitute provides additional thermal capacity beyond the original 10W requirement. The component will operate safely in applications designed for 10W dissipation.

Q: Are there any electrical performance differences between the original and substitute parts?

A: The primary electrical difference is tolerance specification. The original TNP10SA2R00FE provides ±1% tolerance while the TBH25P2R00JE provides ±5% tolerance. Both components deliver 2-ohm resistance. Applications sensitive to tolerance variations should evaluate whether the wider tolerance of the substitute affects circuit specifications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the TNP10SA2R00FE and TBH25P2R00JE are ROHS3 compliant and carry EAR99 export classification. No regulatory barriers exist to substitution.

Q: What is the significance of the different package types?

A: Package type affects physical mounting and thermal characteristics. The TO-220 package of the substitute provides a larger surface area for heat dissipation compared to the TO-126 package of the original part. This contributes to the substitute's higher power rating. Board layout must accommodate the different package dimensions.

Q: Is the substitute part currently available for procurement?

A: Yes. The TBH25P2R00JE is classified as active product status with 836 pieces documented in inventory. The original TNP10SA2R00FE is obsolete, making the substitute the recommended choice for new procurement.
