TNP10SC27R0FE Equivalent & Substitute Parts

Part Overview

The TNP10SC27R0FE is a 27 Ohm, 1% tolerance, 10W through-hole resistor manufactured by Ohmite in the TO-126-2 package. This thin film, moisture-resistant component is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement planning. The part's core electrical characteristics—27 Ohm resistance, ±1% tolerance, and TO-126-2 package—define the substitution criteria for equivalent components.

Substitute Part Grouping Explanation

Substitution for the TNP10SC27R0FE is determined by the following critical parameters:

• Resistance Value: Must be 27 Ohms
• Tolerance: Must be ±1%
• Package / Case: Must be TO-126-2 for mechanical and electrical compatibility
• Power Rating: Minimum 10W; higher ratings are acceptable for thermal margin
• Moisture Resistance: Required feature for environmental durability
• Non-Inductive Construction: Required for circuit performance
• RoHS Compliance: ROHS3 compliance required for regulatory alignment

The MP915-27.0-1% from Caddock Electronics Inc. meets all substitution criteria. While it features a higher power rating (15W) and different composition (thick film vs. thin film), these differences do not preclude substitution when the electrical and mechanical requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

The MP915-27.0-1% is a direct functional substitute for the TNP10SC27R0FE. Both components share identical resistance values, tolerance specifications, and TO-126-2 package geometry. The substitute part carries active product status, ensuring long-term availability and supply chain continuity compared to the obsolete TNP10SC27R0FE.

The MP915-27.0-1% provides a 5W power margin (15W vs. 10W), which enhances thermal performance in applications operating near the original part's power dissipation limits. Both components maintain ROHS3 compliance and moisture resistance, meeting regulatory and environmental durability requirements.

The operating temperature range of the substitute (-55°C ~ 150°C) covers the lower bound of the original part's range (-55°C ~ 155°C). Applications requiring operation above 150°C should verify thermal performance independently.

Frequently Asked Questions (FAQ)

Q: Can the MP915-27.0-1% be used as a direct replacement for the TNP10SC27R0FE?

A: Yes. Both components have identical resistance values (27 Ohms), tolerance (±1%), and TO-126-2 package specifications. Mechanical and electrical compatibility is confirmed.

Q: What is the significance of the higher power rating on the substitute part?

A: The MP915-27.0-1% is rated for 15W versus the original 10W. This provides additional thermal headroom and does not negatively impact circuit performance. The component will operate safely at or below the original 10W specification.

Q: Are there differences in temperature coefficient between the two parts?

A: Yes. The TNP10SC27R0FE has a temperature coefficient of ±50ppm/°C, while the MP915-27.0-1% has a range of -20/+80ppm/°C. For precision applications requiring tight temperature stability, this difference should be evaluated against circuit requirements.

Q: Does the substitute part meet the same compliance standards?

A: Yes. The MP915-27.0-1% is ROHS3 compliant and carries the same ECCN and HTSUS classifications as the original part.

Q: What is the availability status of each part?

A: The TNP10SC27R0FE is obsolete with limited remaining inventory (1379 pcs). The MP915-27.0-1% is active production with current inventory (1192 pcs), ensuring ongoing supply availability.
