TNP10SC200RFE Equivalent & Substitute Parts

Part Overview

The TNP10SC200RFE is a 200 Ohms ±1% 10W through-hole resistor manufactured by Ohmite in TO-126-2 package configuration. This thin film, moisture-resistant, non-inductive component is designed for precision applications requiring low temperature coefficient performance. The part is currently obsolete, making identification of suitable equivalent components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TNP10SC200RFE is determined by the following critical parameters:

• Resistance Value: 200 Ohms (exact match required)
• Tolerance: ±1% (precision specification)
• Package / Case: TO-126-2 (mechanical and electrical interface compatibility)
• Regulatory Compliance: ROHS3 Compliant status
• Moisture Resistance: Required feature for environmental durability

The MP825-200-1% qualifies as a substitute based on matching resistance, tolerance, package type, and compliance requirements. While the substitute features a higher power rating (25W versus 10W) and different composition (thick film versus thin film), these parameters represent design improvements that maintain functional compatibility within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The MP825-200-1% serves as a direct substitute for the obsolete TNP10SC200RFE based on electrical parameter equivalence and regulatory compliance alignment. Both components maintain ROHS3 compliance and identical resistance and tolerance specifications. The substitute's higher power rating (25W) provides design margin without compromising circuit performance. The active product status of the MP825-200-1% ensures continued availability for production and field replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the MP825-200-1% replace the TNP10SC200RFE in existing designs?

A: Yes. Both components share identical resistance (200 Ohms), tolerance (±1%), and package configuration (TO-126-2). The substitute's higher power rating and active product status make it suitable for direct replacement.

Q: What is the significance of the different composition types (thin film vs. thick film)?

A: Composition affects manufacturing process and performance characteristics. The thin film construction of the original part provides specific temperature coefficient performance (±50ppm/°C). The thick film substitute maintains comparable temperature coefficient range (-20/+50ppm/°C) and meets the same moisture resistance and non-inductive requirements.

Q: Are there dimensional differences between these components?

A: Minor dimensional variations exist. The TNP10SC200RFE measures 0.335" L x 0.122" W with 0.598" seated height. The MP825-200-1% measures 0.320" L x 0.110" W with 0.550" seated height. Both fit the TO-126-2 package specification and are compatible with standard PCB layouts designed for this package type.

Q: Does the operating temperature range difference affect substitution?

A: The TNP10SC200RFE operates to 155°C while the MP825-200-1% operates to 150°C. For applications operating below 150°C, this difference is not a limiting factor. Applications requiring operation above 150°C require evaluation against specific circuit requirements.

Q: What is the availability status of these components?

A: The TNP10SC200RFE is obsolete with limited inventory (1340 pcs). The MP825-200-1% is active production with current inventory (1014 pcs), ensuring long-term availability for new designs and field support.
