TNP10SC120RFE Equivalent & Substitute Parts

Part Overview

The TNP10SC120RFE is a through-hole resistor manufactured by Ohmite with a resistance value of 120 ohms, 1% tolerance, and 10-watt power rating in a TO-126 package. This component is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure supply chain availability. Substitute parts must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNP10SC120RFE is determined by the following critical parameters:

Electrical Parameters:

• Resistance value: 120 ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: minimum 10W (equal or greater acceptable)

Mechanical Parameters:

• Package type: TO-126 (exact match required)
• Configuration: Through hole (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS3 compliance (required for modern applications)
• ECCN classification: EAR99 (maintained across substitutes)
• HTSUS code: 8533.21.0090 (maintained across substitutes)

The MP915-120-1% from Caddock Electronics Inc. qualifies as a direct substitute based on matching all critical electrical and mechanical parameters, with the additional benefit of higher power rating (15W versus 10W) and active product status.

Engineering Selection Recommendations

The MP915-120-1% from Caddock Electronics Inc. is the qualified substitute for the obsolete TNP10SC120RFE. Selection rationale is based on the following factors:

Electrical Compatibility: Both components share identical resistance value (120 ohms) and tolerance specification (±1%), ensuring equivalent electrical performance in circuit applications.

Mechanical Compatibility: Both components utilize the TO-126 package configuration with two terminations, enabling direct board-level substitution without layout modifications.

Power Rating: The MP915-120-1% provides 15-watt capability compared to the original 10-watt specification, offering enhanced thermal margin and design flexibility without introducing incompatibility.

Compliance Status: The MP915-120-1% maintains ROHS3 compliance and EAR99 ECCN classification, ensuring regulatory alignment with the original component and current manufacturing standards.

Product Availability: The MP915-120-1% holds active product status with 1484 units in stock, providing reliable supply chain continuity compared to the obsolete TNP10SC120RFE.

Frequently Asked Questions (FAQ)

Q: Can the MP915-120-1% be used as a direct replacement for the TNP10SC120RFE without circuit redesign?

A: Yes. Both components share identical electrical specifications (120 ohms, ±1% tolerance) and mechanical configuration (TO-126 package, two terminations). Direct substitution is supported at the board level without circuit modifications.

Q: What is the significance of the higher 15-watt power rating on the MP915-120-1%?

A: The increased power rating provides additional thermal capacity beyond the original 10-watt specification. This enhancement does not create incompatibility; it expands the operational margin for thermal dissipation in the application.

Q: Are there packaging differences between the TNP10SC120RFE and MP915-120-1%?

A: Both components use TO-126 package configuration. The MP915-120-1% is specified as TO-126-2, indicating a refined package variant. Physical dimensions remain compatible for through-hole board mounting.

Q: Does the MP915-120-1% meet the same compliance requirements as the original component?

A: Yes. The MP915-120-1% is ROHS3 compliant and carries EAR99 ECCN classification, matching the regulatory profile of the TNP10SC120RFE. Both components share the same HTSUS code (8533.21.0090).

Q: What is the composition difference between the two resistors?

A: The MP915-120-1% is specified as thick film construction with moisture-resistant and non-inductive characteristics. The original TNP10SC120RFE composition is not detailed in available specifications. Both are suitable for through-hole applications.

Q: Is the MP915-120-1% available in the same packaging format as the TNP10SC120RFE?

A: The TNP10SC120RFE is supplied in standard packaging, while the MP915-120-1% is available in tube packaging. Both formats are standard for through-hole resistor distribution and do not affect component functionality or board-level compatibility.
