Substitute Part Grouping Explanation

Substitute parts for the Ohmite 20J2R2 are identified based on parametric equivalence across the following critical criteria:

• Resistance value: 2.2 Ohms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±50ppm/°C
• Physical dimensions: 0.394" Dia x 1.858" L (10.00mm x 47.20mm)
• Termination count: 2

The substitute part 20J2R2E maintains identical electrical specifications and mechanical form factor, differing only in packaging configuration (Bulk versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 20J2R2 and 20J2R2E are Active status components from Ohmite with identical electrical and mechanical specifications. The primary distinction is RoHS compliance: the 20J2R2E meets ROHS3 compliance requirements, while the 20J2R2 is RoHS non-compliant. Selection between these parts should be determined by regulatory and compliance requirements applicable to the end application. Both components are suitable for direct substitution in circuits requiring 2.2 Ohm, 10W axial wirewound resistors with ±5% tolerance and ±50ppm/°C temperature coefficient.

Frequently Asked Questions (FAQ)

Q: Can the 20J2R2E replace the 20J2R2 in existing designs?

A: Yes. The 20J2R2E is a parametric equivalent with identical resistance, tolerance, power rating, composition, package type, temperature coefficient, and physical dimensions. The substitute part differs only in packaging configuration and RoHS compliance status.

Q: What is the difference between the standard and Bulk packaging options?

A: Packaging refers to the quantity and container format for component delivery. Both parts maintain identical electrical and mechanical specifications regardless of packaging configuration.

Q: Are there compliance differences between these parts?

A: Yes. The 20J2R2E is ROHS3 compliant, while the 20J2R2 is RoHS non-compliant. Applications subject to RoHS regulations should specify the 20J2R2E.

Q: Do these parts have identical thermal characteristics?

A: Yes. Both parts share the same temperature coefficient of ±50ppm/°C and are rated for 10W power dissipation in the same axial package configuration.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.394" Dia x 1.858" L (10.00mm x 47.20mm) and are compatible with identical PCB layouts and mounting configurations.
