Key Parameters

Substitute Part Grouping Explanation

The Ohmite 22J22R qualifies as a parametric equivalent to the 22J22RE based on the following critical electrical and mechanical parameters:

• Resistance value: 22 Ohms (identical)
• Tolerance: ±5% (identical)
• Power rating: 2W (identical)
• Composition: Wirewound (identical)
• Package configuration: Axial (identical)
• Temperature coefficient: ±30ppm/°C (identical)
• Physical dimensions: 0.220" Dia x 0.421" L (5.60mm x 10.70mm) (identical)
• Features: Flame retardant coating and safety characteristics (identical)

The primary difference between these parts is packaging format (Box versus Bulk) and RoHS compliance status. Both parts share identical electrical performance and mechanical form factor, making them functionally interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Selection between 22J22RE and 22J22R depends on regulatory and procurement requirements:

Select 22J22RE when:

• RoHS compliance is mandatory for the end application or market
• Boxed packaging is required for inventory management or traceability
• Compliance documentation must be provided to customers or regulatory bodies

Select 22J22R when:

• RoHS compliance is not a requirement
• Bulk packaging is acceptable for manufacturing operations
• Cost optimization through bulk procurement is prioritized
• The application does not fall under RoHS-regulated markets

Both parts are in active production status and maintain identical electrical and mechanical specifications, ensuring direct functional interchangeability in circuit design.

Frequently Asked Questions (FAQ)

Q: Can 22J22R be used as a direct replacement for 22J22RE in all applications?

A: Yes, from an electrical and mechanical standpoint. The 22J22R provides identical resistance, tolerance, power rating, temperature coefficient, and physical dimensions. The substitution decision depends on RoHS compliance requirements specific to your application or market.

Q: What is the difference between Box and Bulk packaging?

A: Box packaging (22J22RE) typically includes individual component packaging suitable for traceability and compliance documentation. Bulk packaging (22J22R) is designed for high-volume manufacturing operations where components are supplied in larger quantities without individual packaging.

Q: Are there any performance differences between these parts?

A: No. Both parts are manufactured by Ohmite using identical wirewound composition, feature the same flame retardant coating and safety characteristics, and operate within the same temperature coefficient range (±30ppm/°C).

Q: Which part should I specify for a new design?

A: Specify 22J22RE if RoHS compliance is required or if your supply chain mandates compliant components. Specify 22J22R only if your application explicitly permits non-RoHS components and bulk packaging is acceptable.

Q: Are both parts currently available?

A: Yes. 22J22RE has 966 units in stock, and 22J22R has 1106 units in stock, both in active production status.
