Substitute Part Grouping Explanation

The 90J30RE qualifies as a parametric equivalent to the 90J30R based on the following criteria:

• Identical resistance value: 30 Ohms
• Identical tolerance: ±5%
• Identical power rating: 11W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical temperature coefficient: ±30ppm/°C
• Identical features: Flame Retardant Coating, Safety
• Identical physical dimensions: 0.343" Dia x 1.811" L (8.70mm x 46.00mm)
• Identical number of terminations: 2
• Same manufacturer series: 90

Both parts maintain full electrical and mechanical compatibility within the Ohmite 90 series. The primary distinction is packaging format and compliance certification status.

Parameter Comparison

Engineering Selection Recommendations

Both the 90J30R and 90J30RE are Active status components suitable for direct substitution in applications requiring 30 Ohm, 11W wirewound axial resistors. Selection between these parts should be based on compliance requirements and procurement specifications:

The 90J30RE offers ROHS3 compliance, making it the appropriate choice for applications subject to RoHS3 regulatory requirements. The 90J30R remains suitable for applications where RoHS compliance is not mandated. Both parts are electrically and mechanically identical, ensuring circuit performance equivalence. Packaging format differs between standard and bulk options; selection depends on order quantity and inventory management requirements.

Frequently Asked Questions (FAQ)

Q: Can the 90J30RE directly replace the 90J30R in existing designs?

A: Yes. Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, temperature coefficient, and physical dimensions. Direct substitution is valid from a circuit performance perspective.

Q: What is the primary difference between these two parts?

A: The 90J30RE is ROHS3 compliant while the 90J30R is RoHS non-compliant. Both parts are otherwise identical in electrical specifications and mechanical form factor.

Q: Are there packaging considerations when substituting between these parts?

A: The 90J30R uses standard packaging while the 90J30RE uses bulk packaging. This distinction affects order quantities and storage requirements but does not impact electrical or mechanical compatibility.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory and compliance requirements. For applications requiring RoHS3 compliance, specify the 90J30RE. For applications without RoHS compliance mandates, either part is acceptable based on availability and procurement preferences.

Q: Do these parts have identical temperature performance?

A: Yes. Both parts share an identical temperature coefficient of ±30ppm/°C, ensuring equivalent thermal stability across the operating range.
