TNP10SC25R0FE Equivalent & Substitute Parts

Part Overview

The TNP10SC25R0FE is a 25 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—25 Ohm resistance, ±1% tolerance, and TO-126-2 package—define the substitution criteria for equivalent components.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNP10SC25R0FE is determined by the following parameters:

• Resistance Value: Must be 25 Ohms
• Tolerance: Must be ±1%
• Package: Must be TO-126-2
• Moisture Resistance: Required feature
• Non-Inductive: Required feature
• RoHS Compliance: ROHS3 Compliant status required

The power rating may exceed the original 10W specification, provided all other electrical and mechanical parameters are met. Composition (thin film vs. thick film) and temperature coefficient variations are acceptable within the operating temperature range constraints.

Parameter Comparison

Engineering Selection Recommendations

The MP915-25.0-1% from Caddock Electronics Inc. meets all substitution criteria for the TNP10SC25R0FE. Both components share identical resistance, tolerance, and TO-126-2 package specifications. The substitute provides a higher power rating (15W vs. 10W), which offers design margin without compromising electrical performance. Both parts maintain ROHS3 compliance and moisture resistance characteristics required for the application.

The substitute is classified as active product status, ensuring continued availability and supply chain stability compared to the obsolete TNP10SC25R0FE. The operating temperature range of the substitute (-55°C ~ 150°C) covers the majority of the original part's range, with a 5°C reduction at the upper limit.

Frequently Asked Questions (FAQ)

Q: Can the MP915-25.0-1% directly replace the TNP10SC25R0FE in existing designs?

A: Yes. Both components share identical resistance (25 Ohms), tolerance (±1%), and TO-126-2 package specifications. The substitute's higher power rating (15W) and active product status make it suitable for direct substitution.

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

A: The MP915-25.0-1% is rated for 15W compared to the original 10W. This higher rating provides additional thermal margin and does not negatively impact circuit performance when the original 10W specification is sufficient.

Q: Are there package compatibility concerns between the two parts?

A: No. Both the TNP10SC25R0FE and MP915-25.0-1% use the TO-126-2 package with identical termination count (2). Physical dimensions are comparable, with the substitute slightly smaller in length and height.

Q: How do the temperature coefficients differ between these parts?

A: The TNP10SC25R0FE has a temperature coefficient of ±50ppm/°C, while the MP915-25.0-1% has -20/+80ppm/°C. Both remain within acceptable tolerance drift across the operating temperature range for most applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the TNP10SC25R0FE and MP915-25.0-1% are ROHS3 compliant, meeting environmental and regulatory requirements.
