Substitute Part Grouping Explanation

Substitution of the MPR20HR47J is determined by strict equivalence across the following critical parameters:

• Resistance Value: 470 mOhms (exact match required)
• Tolerance: ±5% (electrical accuracy specification)
• Power Rating: 20W (thermal dissipation capability)
• Package Configuration: TO-220-2 (mechanical and thermal interface)
• Composition: Thick Film (construction method)
• Temperature Coefficient: ±250ppm/°C (temperature stability)
• Operating Temperature Range: -55°C to 155°C (environmental limits)

The substitute part RTO020FR4700JTE3 manufactured by Vishay Sfernice meets all these critical parameters, enabling direct functional replacement in circuit applications.

Engineering Selection Recommendations

The RTO020FR4700JTE3 is the qualified substitute for the obsolete MPR20HR47J. Selection of this substitute is based on the following engineering criteria:

Product Status: The MPR20HR47J is obsolete, whereas the RTO020FR4700JTE3 maintains active product status with current manufacturing support and availability (1300 pcs in stock versus 913 pcs for the original part).

Electrical Equivalence: Both components provide identical electrical specifications across resistance value, tolerance, power rating, and temperature coefficient, ensuring functional interchangeability in circuit designs.

Regulatory Compliance: The RTO020FR4700JTE3 is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Mechanical Compatibility: Both parts utilize the TO-220-2 package configuration with two terminations, ensuring compatibility with existing PCB layouts and thermal management systems. Minor dimensional variations (height and length) do not affect functional performance or mounting requirements.

Thermal Performance: Identical operating temperature range (-55°C to 155°C) and temperature coefficient (±250ppm/°C) ensure equivalent thermal behavior across all operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the RTO020FR4700JTE3 be used as a direct replacement for the MPR20HR47J?

A: Yes. The RTO020FR4700JTE3 meets all critical electrical and mechanical parameters required for direct substitution, including resistance value, tolerance, power rating, package type, and operating temperature range.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The MPR20HR47J measures 0.417" L x 0.177" W with a maximum seated height of 0.748", while the RTO020FR4700JTE3 measures 0.398" L x 0.177" W with a maximum seated height of 0.606". These differences do not affect PCB mounting or thermal interface performance.

Q: What is the significance of the TO-220-2 package for these resistors?

A: The TO-220-2 package provides a two-terminal through-hole configuration with integrated thermal interface capability, suitable for high-power dissipation applications. Both parts utilize this identical package type.

Q: Does the RTO020FR4700JTE3 provide the same non-inductive characteristics as the MPR20HR47J?
