Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 95J250 is determined by strict equivalence across the following parameters: resistance value (250 Ohms), tolerance (±5%), power rating (5W), composition (Wirewound), package type (Axial), physical dimensions (0.264" Dia x 0.969" L), temperature coefficient (±30ppm/°C), and termination count (2). The identified substitute part maintains all electrical and mechanical specifications while differing only in packaging format and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 95J250 and 95J250E are Active status components from Ohmite's Series 90 product line. Selection between these parts should be based on regulatory and procurement requirements. The 95J250E offers ROHS3 compliance, making it suitable for applications subject to RoHS3 regulations. The 95J250 is appropriate for applications without RoHS compliance mandates. Both parts are electrically and mechanically identical, differing only in packaging format (standard versus bulk) and environmental compliance certification. Inventory availability should be considered in procurement decisions, as both parts maintain active stock levels.

Frequently Asked Questions (FAQ)

Q: Are the 95J250 and 95J250E electrically interchangeable? A: Yes. Both parts have identical resistance (250 Ohms), tolerance (±5%), power rating (5W), temperature coefficient (±30ppm/°C), and composition (Wirewound). They are direct electrical equivalents.

Q: What is the difference between the 95J250 and 95J250E? A: The primary differences are packaging format (standard versus bulk) and RoHS compliance status. The 95J250E is ROHS3 compliant, while the 95J250 is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Can I use the 95J250E as a direct replacement for the 95J250 in existing designs? A: Yes. The 95J250E maintains identical physical dimensions (0.264" Dia x 0.969" L), axial package configuration, and all electrical parameters. It is a direct mechanical and electrical substitute.

Q: Which part should I select for new designs? A: For new designs subject to RoHS3 regulations, select the 95J250E. For applications without RoHS compliance requirements, either part is suitable based on availability and procurement preferences.

Q: Are there any thermal or performance differences between these parts? A: No. Both parts have identical temperature coefficient (±30ppm/°C) and power dissipation characteristics (5W). Thermal performance is equivalent.
