MPR20C22RJ Equivalent & Substitute Parts

Part Overview

The MPR20C22RJ is a 22 Ohm, 5% tolerance, 20W through-hole resistor manufactured by TE Connectivity Passive Product in the TO-220-2 package. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing applications and new designs. The part features flame-proof construction, non-inductive design, and safety-rated thick film composition suitable for high-power applications requiring thermal management through the TO-220 package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPR20C22RJ is determined by the following critical parameters: package type (TO-220-2), composition (thick film), tolerance (±5%), and operating temperature range compatibility. Substitute parts must maintain the same or superior power dissipation capability, identical or compatible package footprint, and equivalent electrical performance within the specified tolerance and temperature operating window.

The identified substitute parts are grouped into two categories:

Category 1: Direct Resistance and Power Match – Parts maintaining the exact 22 Ohm resistance value and 20W power rating with identical TO-220-2 packaging.

Category 2: Functional Equivalents with Parameter Variation – Parts with different resistance values or power ratings but compatible TO-220-2 packaging and thick film construction, suitable for applications where circuit design permits resistance or power rating adjustment.

Parameter Comparison

Engineering Selection Recommendations

RTO020F22R00JTE3 (Vishay Sfernice) is the primary substitute for direct replacement applications. This part maintains identical resistance (22 Ohms), tolerance (±5%), power rating (20W), and operating temperature range (-55°C to 155°C) as the MPR20C22RJ. The RTO020F22R00JTE3 is active in production status with ROHS3 compliance and REACH Unaffected designation, ensuring long-term availability and regulatory compliance. The higher temperature coefficient (±150ppm/°C versus ±50ppm/°C) represents the only electrical parameter variance and is acceptable for applications where the original ±50ppm/°C specification is not critical to circuit performance.

MPT30C20RJ (TE Connectivity Passive Product) serves as a functional equivalent for applications where circuit design permits a 20 Ohm resistance value (9% reduction from 22 Ohms) and higher power dissipation capability (30W versus 20W) is beneficial. This part is active in production status with identical temperature coefficient (±50ppm/°C) and compatible TO-220-2 packaging. The operating temperature range (-65°C to 150°C) provides extended low-temperature capability but slightly reduced maximum temperature. This substitute is suitable for thermal margin applications where the increased power rating provides design flexibility.

Both substitute parts are manufactured by established suppliers with active production status, ensuring component availability and supply chain continuity for the obsolete MPR20C22RJ.

Frequently Asked Questions (FAQ)

Q: Can the RTO020F22R00JTE3 be used as a direct replacement for the MPR20C22RJ in all applications?

A: The RTO020F22R00JTE3 is electrically and mechanically compatible with the MPR20C22RJ for applications where the temperature coefficient specification of ±150ppm/°C is acceptable. Both parts share identical resistance (22 Ohms), tolerance (±5%), power rating (20W), package type (TO-220-2), and operating temperature range (-55°C to 155°C). Applications requiring the original ±50ppm/°C temperature coefficient specification require evaluation of circuit sensitivity to this parameter.

Q: What is the primary difference between the MPT30C20RJ and the MPR20C22RJ?

A: The MPT30C20RJ differs in two key parameters: resistance value (20 Ohms versus 22 Ohms) and power rating (30W versus 20W). The 20 Ohm resistance represents a 9% reduction from the original 22 Ohm specification. This substitute is applicable only to circuits where the lower resistance value and higher power dissipation capability are compatible with design requirements. Temperature coefficient and operating temperature range remain equivalent to the original part.

Q: Are all substitute parts available in the same packaging format?

A: All identified substitute parts utilize the TO-220-2 package format, ensuring mechanical and thermal compatibility with the original MPR20C22RJ. Physical dimensions vary slightly between manufacturers, but all parts are designed for identical mounting and thermal interface applications.

Q: What is the significance of the product status designation for these parts?

A: The MPR20C22RJ is classified as obsolete, indicating discontinued production and potential supply constraints. Both substitute parts (RTO020F22R00JTE3 and MPT30C20RJ) maintain active production status, ensuring long-term availability and supply chain reliability for new designs and ongoing production requirements.

Q: How do compliance certifications differ between the main part and substitute parts?

A: The MPR20C22RJ does not specify RoHS or REACH compliance status. The RTO020F22R00JTE3 is ROHS3 compliant and REACH Unaffected. The MPT30C20RJ is ROHS3 compliant with undefined REACH status. Applications subject to regulatory compliance requirements should verify that selected substitute parts meet applicable environmental and safety standards.
