Key Parameters

Substitute Part Grouping Explanation

The Ohmite 90J75RE qualifies as a parametric equivalent to the 90J75R based on the following criteria:

Electrical Parameters (Identical):

• Resistance: 75 Ohms
• Tolerance: ±5%
• Power Rating: 11W
• Temperature Coefficient: ±30ppm/°C

Mechanical Parameters (Identical):

• Composition: Wirewound
• Package Type: Axial
• Size / Dimension: 0.343" Dia x 1.811" L (8.70mm x 46.00mm)
• Number of Terminations: 2
• Features: Flame Retardant Coating, Safety

Packaging Difference:

• 90J75R: Box packaging
• 90J75RE: Bulk packaging

The substitution is valid for applications where packaging format does not impose constraints. Both parts maintain identical electrical performance and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

90J75R Selection Criteria:

• Applications requiring RoHS non-compliant components
• Box packaging requirement for specific supply chain or handling procedures
• Existing inventory availability of 782 units

90J75RE Selection Criteria:

• Applications requiring ROHS3 compliance
• Bulk packaging acceptable for manufacturing or assembly operations
• Higher inventory availability (1018 units) supports larger production volumes

Both parts are active products from Ohmite with identical electrical and mechanical specifications. Selection between them depends on regulatory compliance requirements and packaging format constraints specific to the application or supply chain.

Frequently Asked Questions (FAQ)

Q: Can 90J75RE replace 90J75R in all applications? A: Yes, provided that ROHS3 compliance is acceptable and bulk packaging does not conflict with supply chain requirements. All electrical and mechanical parameters are identical.

Q: What is the difference between Box and Bulk packaging? A: Box packaging typically provides individual component packaging suitable for smaller quantities or specific handling requirements. Bulk packaging is used for larger production volumes and standard manufacturing operations. The resistor itself is identical in both formats.

Q: Are there any performance differences between these parts? A: No. Both parts have identical resistance (75 Ohms), tolerance (±5%), power rating (11W), temperature coefficient (±30ppm/°C), and physical dimensions (0.343" Dia x 1.811" L).

Q: What does ROHS3 compliance mean? A: ROHS3 compliance indicates the component meets Restriction of Hazardous Substances Directive requirements. The 90J75R is RoHS non-compliant, while the 90J75RE is ROHS3 compliant. Selection depends on regulatory requirements for the end application.

Q: Can these parts be used interchangeably on the same PCB? A: Yes. Both parts have identical axial package dimensions and two terminations, allowing direct substitution in through-hole designs without layout modifications.

Q: Which part should I choose for new designs? A: Selection depends on regulatory compliance requirements. If ROHS3 compliance is required, use 90J75RE. If RoHS non-compliance is acceptable, either part is suitable based on packaging and inventory needs.
