Substitute Part Grouping Explanation

The 90J25RE qualifies as a parametric equivalent to the 90J25R based on identical electrical and mechanical specifications. Substitution is valid when the following criteria are met:

• Resistance value: 25 Ohms (exact match)
• Tolerance: ±5% (exact match)
• Power rating: 11W (exact match)
• Composition: Wirewound (exact match)
• Package: Axial (exact match)
• Physical dimensions: 0.343" Dia x 1.811" L (exact match)
• Temperature coefficient: ±30ppm/°C (exact match)
• Features: Flame retardant coating and safety features (exact match)

The primary difference between these parts is packaging format and RoHS compliance status, which do not affect electrical or mechanical interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 90J25R and 90J25RE are active production parts from Ohmite with identical electrical and mechanical characteristics. Selection between these parts should be based on regulatory and compliance requirements:

The 90J25RE is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to European Union environmental regulations. The 90J25R is RoHS non-compliant and should be selected only when legacy designs or specific application requirements mandate non-compliant components. Both parts maintain equivalent performance in circuit operation, with no functional differences in resistance value, power dissipation, temperature stability, or physical form factor.

Frequently Asked Questions (FAQ)

Q: Can the 90J25RE be used as a direct replacement for the 90J25R?

A: Yes. The 90J25RE is electrically and mechanically identical to the 90J25R. All critical parameters including resistance, tolerance, power rating, temperature coefficient, and physical dimensions are equivalent. The parts are interchangeable in circuit applications.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format and RoHS compliance status. The 90J25R is supplied in standard packaging and is RoHS non-compliant. The 90J25RE is supplied in bulk packaging and is ROHS3 compliant. These differences do not affect electrical performance or mechanical fit.

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, specify the 90J25RE. For legacy designs or applications without RoHS requirements, either part is acceptable based on availability and procurement preferences.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.343" diameter by 1.811" length (8.70mm x 46.00mm). They are identical in form factor and will fit the same PCB footprints and mechanical assemblies.

Q: What is the temperature coefficient specification?

A: Both parts have a temperature coefficient of ±30ppm/°C, indicating stable resistance performance across the operating temperature range.
