Ohmite 25J75R Equivalent & Substitute Parts

Part Overview

The Ohmite 25J75R is a 75 Ohm, 5% tolerance, 5W axial wirewound resistor with flame retardant coating and safety features. This component is classified as Active product status and is designed for through-hole applications requiring reliable power dissipation in industrial and commercial electronics. Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or when design requirements permit alternative packaging or compliance specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 25J75R is determined by strict electrical and mechanical parameter matching. All substitute parts must maintain identical resistance value (75 Ohms), tolerance (±5%), power rating (5W), composition (Wirewound), package type (Axial), and core safety features (Flame Retardant Coating, Safety). Temperature coefficient and termination count must also remain constant at ±30ppm/°C and 2 terminations respectively.

The substitute parts identified—25J75RE and 95J75R—satisfy all critical electrical parameters. Dimensional variations and compliance differences are secondary considerations that do not affect functional interchangeability in circuit applications where the 25J75R is specified.

Parameter Comparison

Engineering Selection Recommendations

25J75RE (Direct Substitute): This part is electrically and mechanically identical to the 25J75R with the primary distinction being RoHS compliance status. The 25J75RE achieves RoHS Compliant certification, making it the preferred selection for applications subject to RoHS regulatory requirements. Packaging is specified as Bulk. Dimensional specifications are identical, ensuring direct board-level compatibility without layout modifications.

95J75R (Manufacturer Recommended Substitute): This part represents the manufacturer's recommended alternative from the Series 90 product line. It maintains all critical electrical parameters and safety features. Physical dimensions are slightly reduced (0.264" Dia x 0.969" L versus 0.276" Dia x 1.016" L), which may provide space advantages in compact layouts. This part is designated as MFR Recommended by Ohmite, indicating manufacturer validation for cross-application use. RoHS non-compliant status matches the original 25J75R specification.

Selection between 25J75RE and 95J75R depends on regulatory compliance requirements and available board space. Both parts are Active status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 25J75RE be used as a direct replacement for 25J75R? A: Yes. The 25J75RE is electrically and mechanically identical to the 25J75R. The primary difference is RoHS compliance status. If your application or supply chain requires RoHS Compliant components, 25J75RE is the appropriate selection. Dimensional specifications are identical, requiring no board layout changes.

Q: What is the difference between 25J75RE and 95J75R? A: Both parts share identical electrical specifications (75 Ohms, ±5%, 5W, Wirewound, Axial). The 95J75R has slightly smaller physical dimensions (0.264" Dia x 0.969" L versus 0.276" Dia x 1.016" L) and belongs to Ohmite's Series 90 product line. The 25J75RE belongs to Series 20. Both are manufacturer-validated substitutes with confirmed inventory.

Q: Are dimensional differences between 25J75R and 95J75R significant? A: Dimensional differences are minor (approximately 0.012" diameter reduction and 0.047" length reduction). These variations may be relevant only in space-constrained applications. Electrical performance and safety characteristics remain identical. Verify board layout clearances if space is a critical design constraint.

Q: Which substitute should I select for a new design? A: Selection depends on regulatory requirements. For RoHS-compliant applications, specify 25J75RE. For applications without RoHS requirements, either 25J75RE or 95J75R is acceptable. Consult your supply chain and regulatory documentation to determine compliance obligations.

Q: Are all substitute parts currently in stock? A: Yes. 25J75R has 983 units, 25J75RE has 965 units, and 95J75R has 765 units available as new original stock.

Q: Do substitute parts have the same safety certifications? A: Yes. All three parts feature Flame Retardant Coating and Safety characteristics. Electrical performance specifications including Temperature Coefficient (±30ppm/°C) are identical across all substitute options.
