Substitute Part Grouping Explanation

Substitution eligibility for the 25J35R is determined by strict equivalence across the following critical parameters:

• Resistance value: 35 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±30ppm/°C
• Physical dimensions: 0.276" Dia x 1.016" L (7.00mm x 25.80mm)
• Number of terminations: 2
• Features: Flame Retardant Coating, Safety

The 25J35RE meets all electrical and mechanical requirements for direct substitution. Differences in packaging format (Bulk vs. standard) and RoHS compliance status do not affect functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 25J35R and 25J35RE are active production components from Ohmite's Series 20 line. The 25J35RE offers ROHS3 compliance, whereas the 25J35R is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 25J35RE is the appropriate selection. Both parts maintain identical electrical performance, mechanical fit, and thermal characteristics. Inventory availability differs, with 25J35RE offering 1160 units versus 919 units for the 25J35R. Selection between these parts should be based on regulatory compliance requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the 25J35RE be used as a direct replacement for the 25J35R in existing designs?

A: Yes. The 25J35RE is electrically and mechanically equivalent to the 25J35R. All critical parameters—resistance value, tolerance, power rating, temperature coefficient, and physical dimensions—are identical. The parts are pin-compatible and functionally interchangeable in circuit applications.

Q: What is the difference between the 25J35R and 25J35RE?

A: The primary differences are packaging format and RoHS compliance status. The 25J35R uses standard packaging and is RoHS non-compliant, while the 25J35RE uses Bulk packaging and is ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Does the packaging difference (standard vs. Bulk) affect circuit performance?

A: No. Packaging format refers to the quantity and presentation method for procurement and inventory management. It does not affect the component's electrical performance, thermal characteristics, or mechanical fit in the circuit.

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, specify the 25J35RE. For applications without RoHS requirements, either part is suitable. Verify supply chain availability for your production timeline.

Q: Are there any thermal or frequency limitations when substituting these parts?

A: No. Both parts share identical temperature coefficients (±30ppm/°C) and thermal performance characteristics. Substitution does not introduce thermal or frequency-related limitations.
