Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R5J50R is determined by the following critical parameters:

• Resistance Value: 50 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 5W minimum (equal or greater acceptable)
• Composition: Wirewound (required for thermal and frequency characteristics)
• Package Type: Radial Lead (mechanical compatibility requirement)
• Manufacturer: Ohmite (series consistency)

The R5J50RE qualifies as a parametric equivalent based on matching resistance, tolerance, and package configuration. The R5J50RE is rated at 5.25W, which exceeds the 5W requirement of the primary part, providing equivalent or superior performance in power dissipation applications.

Parameter Comparison

Engineering Selection Recommendations

Both the R5J50R and R5J50RE are active Ohmite products with identical electrical specifications for resistance and tolerance. The R5J50RE provides a higher power rating (5.25W versus 5W), which offers improved thermal margin in applications operating near maximum power dissipation limits. Both parts maintain RoHS non-compliant status and are manufactured to the same electrical and mechanical standards. Selection between these parts should be based on inventory availability and application thermal requirements. The R5J50RE is suitable for direct substitution in all applications where the R5J50R is specified.

Frequently Asked Questions (FAQ)

Q: Can the R5J50RE replace the R5J50R in existing designs?

A: Yes. The R5J50RE is electrically and mechanically equivalent to the R5J50R. Both parts share identical resistance (50 Ohms), tolerance (±5%), and radial lead package configuration. The higher power rating of the R5J50RE (5.25W) does not create compatibility issues and may provide additional thermal margin.

Q: What is the significance of the power rating difference between these parts?

A: The R5J50R is rated at 5W while the R5J50RE is rated at 5.25W. This difference reflects thermal design variations but does not affect electrical performance. The R5J50RE can safely operate in any application designed for the R5J50R without derating.

Q: Are there packaging differences between these substitutes?

A: Both parts use radial lead packages suitable for through-hole PCB mounting. The R5J50R is supplied in standard packaging while the R5J50RE is supplied in bulk packaging. This distinction affects procurement and handling but not electrical or mechanical compatibility.

Q: Do these parts have different compliance certifications?

A: Both the R5J50R and R5J50RE share identical RoHS non-compliant status and ECCN/HTSUS classifications. No compliance differences exist between these parts.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection should be based on current inventory availability and supply chain considerations. Both parts are active products from Ohmite with equivalent performance characteristics.
