Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 95J300 is determined by the following critical parameters:

• Resistance value: 300 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.264" Dia x 0.969" L (exact match required)
• Temperature coefficient: ±30ppm/°C (exact match required)
• Features: Flame retardant coating and safety characteristics (exact match required)

The substitute part 95J300E meets all electrical and mechanical parameters specified above, differing only in packaging configuration (Bulk versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 95J300 and 95J300E are Active status components manufactured by Ohmite with identical electrical and mechanical specifications. Selection between these parts is determined by compliance requirements and packaging needs:

• 95J300: Select when RoHS non-compliant components are acceptable for the application and standard packaging is required.
• 95J300E: Select when ROHS3 compliance is mandated by design specifications or regulatory requirements. This part is also available in Bulk packaging for high-volume procurement scenarios.

Both parts are functionally interchangeable in circuits where the specified electrical parameters (300 Ohms, ±5%, 5W, ±30ppm/°C) and physical form factor (Axial, 0.264" Dia x 0.969" L) are required.

Frequently Asked Questions (FAQ)

Q: Can 95J300E be used as a direct replacement for 95J300?

A: Yes. The 95J300E is electrically and mechanically identical to the 95J300. The primary differences are RoHS compliance status (ROHS3 Compliant versus non-compliant) and packaging configuration (Bulk versus standard). Direct substitution is valid when compliance requirements permit.

Q: What is the significance of the RoHS compliance difference?

A: RoHS3 compliance indicates the 95J300E meets Restriction of Hazardous Substances regulations. If your application or end-market requires RoHS compliance, the 95J300E must be selected. The 95J300 is suitable only for applications where RoHS non-compliant components are acceptable.

Q: Are the physical dimensions identical between 95J300 and 95J300E?

A: Yes. Both parts have identical dimensions of 0.264" Dia x 0.969" L (6.70mm x 24.60mm). PCB layout and mechanical clearance requirements are identical for both parts.

Q: What does "Bulk" packaging mean for the 95J300E?

A: Bulk packaging indicates the component is supplied in loose form without individual packaging, typically used for high-volume orders. Standard packaging for the 95J300 may include individual wrapping or tape-and-reel configuration. Verify packaging requirements with your procurement specifications before ordering.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts have identical temperature coefficient (±30ppm/°C), power rating (5W), and thermal characteristics. Performance in thermal cycling and high-temperature applications is equivalent.
