Substitute Part Grouping Explanation

Substitution eligibility for the 22J2R0 is determined by the following critical parameters:

• Resistance value: 2 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial (exact match required)
• Physical dimensions: 0.220" Dia x 0.421" L (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)

The identified substitute part 22J2R0E meets all electrical and mechanical parameters. The primary distinction between the main part and substitute is packaging format (tape/reel versus bulk) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both 22J2R0 and 22J2R0E are active production components from Ohmite's 20 series with identical electrical and mechanical specifications. Selection between these parts depends on application requirements and regulatory compliance:

The 22J2R0 is suitable for applications where RoHS non-compliance is acceptable or where specific tape/reel packaging is required for automated assembly processes.

The 22J2R0E is the appropriate selection for applications requiring ROHS3 compliance. This variant maintains all electrical performance characteristics while meeting modern environmental and regulatory standards. The bulk packaging format of 22J2R0E accommodates manual assembly and component stocking workflows.

Both parts are functionally interchangeable in circuits where the specified electrical parameters (2 Ohms, ±5%, 2W, ±50ppm/°C) and physical form factor (axial, 5.60mm x 10.70mm) are required.

Frequently Asked Questions (FAQ)

Q: Can 22J2R0E replace 22J2R0 in all applications?

A: Yes, 22J2R0E is electrically and mechanically equivalent to 22J2R0. The substitute maintains identical resistance, tolerance, power rating, temperature coefficient, and physical dimensions. The primary differences are packaging format and RoHS compliance status.

Q: What is the difference between tape/reel and bulk packaging?

A: Tape/reel packaging (22J2R0) is designed for automated pick-and-place assembly equipment. Bulk packaging (22J2R0E) is supplied loose and is suitable for manual assembly or component stocking. Both formats contain the same component.

Q: Does RoHS3 compliance affect electrical performance?

A: No. RoHS3 compliance is a regulatory and material composition requirement, not an electrical specification. Both 22J2R0 and 22J2R0E deliver identical electrical performance in circuit applications.

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

A: No. Both parts share identical temperature coefficient (±50ppm/°C), power rating (2W), and construction (wirewound with flame retardant coating and safety features). Thermal and reliability characteristics are equivalent.

Q: Which part should be selected for new designs?

A: For new designs, 22J2R0E is recommended due to ROHS3 compliance, which aligns with current environmental regulations and supply chain standards. Selection of 22J2R0 should be limited to legacy designs or applications where RoHS non-compliance is explicitly required.
