TA025PW100RJ Equivalent & Substitute Parts

Part Overview

The TA025PW100RJ is a 100 Ohm, 25W through-hole radial thick film resistor manufactured by Ohmite as part of the Power Chip® TA series. This component is currently active in production with 860 units in stock. The part operates across a temperature range of -55°C to 180°C and is designed for applications requiring high power dissipation in a compact radial package format.

Identifying equivalent and substitute parts is necessary when addressing inventory constraints, supply chain disruptions, or when specific compliance requirements must be met for new designs or production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TA025PW100RJ is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 Ohms
• Tolerance: ±5%
• Power rating: 25W
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 180°C
• Package configuration: Radial with 4 terminations
• Physical dimensions: 2.220" L × 0.240" W with maximum seated height of 1.189"

Parts meeting all these criteria are classified as parametric equivalents and may be substituted in applications where the original part number is specified, provided that packaging and compliance requirements are compatible with the end application.

Parameter Comparison

Engineering Selection Recommendations

Both TA025PW100RJ and TA025PW100RJE are active production parts from Ohmite with identical electrical and mechanical specifications. The primary distinction between these parts is compliance certification and packaging format.

The TA025PW100RJE variant is ROHS3 compliant with MSL rating of 1 (Unlimited), making it suitable for applications subject to RoHS directives and moisture-sensitive environments. The TA025PW100RJ is RoHS non-compliant and carries no MSL rating.

Selection between these parts should be based on the specific compliance requirements of the end application and the acceptable packaging format (standard versus bulk).

Frequently Asked Questions (FAQ)

Q: Can TA025PW100RJE be used as a direct replacement for TA025PW100RJ?

A: Yes. Both parts are parametric equivalents with identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. Substitution is valid from an electrical and mechanical standpoint. Compliance and packaging differences must be evaluated for the specific application.

Q: What is the difference between standard and bulk packaging?

A: Standard packaging refers to the original equipment manufacturer (OEM) packaging format, while bulk packaging indicates alternative packaging suitable for high-volume procurement. Both formats contain the same component; the difference is in the quantity per container and protective packaging method.

Q: Does RoHS3 compliance affect component performance?

A: No. RoHS3 compliance is a regulatory certification indicating the absence of restricted substances. It does not alter the electrical performance, power rating, or operating characteristics of the resistor.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component can be stored indefinitely without moisture-related degradation, provided standard storage conditions are maintained. This classification applies to the TA025PW100RJE variant.

Q: Are these parts interchangeable in PCB assembly?

A: Yes, provided the PCB design accommodates the radial package format with 4 terminations and the specified physical dimensions. No design modifications are required for electrical or mechanical compatibility.
