Substitute Part Grouping Explanation

Substitution for the Ohmite 22J2R2 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.2 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±50ppm/°C
• Physical dimensions: 0.220" Dia x 0.421" L (5.60mm x 10.70mm)
• Termination count: 2

The substitute part 22J2R2E maintains identical electrical and mechanical specifications, with the primary distinction being packaging format and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Selection between the Ohmite 22J2R2 and 22J2R2E is determined by compliance and supply requirements:

The 22J2R2E is the appropriate selection for applications requiring RoHS compliance. Both parts are electrically and mechanically identical, with the 22J2R2E meeting RoHS Compliant status while the 22J2R2 is RoHS non-compliant.

The 22J2R2 remains suitable for applications where RoHS compliance is not a requirement and standard packaging is preferred.

Packaging format differs between the two parts: the 22J2R2 uses standard packaging while the 22J2R2E is supplied in bulk format. This distinction affects inventory management and procurement workflows but does not impact electrical performance or mechanical fit.

Frequently Asked Questions (FAQ)

Q: Are the 22J2R2 and 22J2R2E electrically identical?

A: Yes. Both parts have identical resistance (2.2 Ohms), tolerance (±5%), power rating (2W), temperature coefficient (±50ppm/°C), and composition (wirewound). They are direct electrical equivalents.

Q: Can the 22J2R2E be used as a direct replacement for the 22J2R2?

A: Yes, for applications where RoHS compliance is required or acceptable. The parts are mechanically and electrically interchangeable with identical axial package dimensions (0.220" Dia x 0.421" L).

Q: What is the difference in packaging between these parts?

A: The 22J2R2 uses standard packaging while the 22J2R2E is supplied in bulk format. This affects order quantities and storage but does not impact circuit performance or board-level compatibility.

Q: Which part should be selected for new designs?

A: Selection depends on compliance requirements. For designs requiring RoHS compliance, specify the 22J2R2E. For applications without RoHS requirements, either part is suitable based on packaging and supply availability.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 0.220" Dia x 0.421" L (5.60mm x 10.70mm) and are housed in axial package configuration with 2 terminations.
