Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 23J2R2 is determined by the following critical parameters:

• Resistance value: 2.2 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.220" Dia x 0.516" L (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Features: Flame retardant coating and safety characteristics (exact match required)

The identified substitute part 23J2R2E meets all electrical and mechanical parameters. The primary difference is packaging configuration (Bulk versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 23J2R2 and 23J2R2E are active production parts from Ohmite with identical electrical and mechanical specifications. Selection between these parts depends on compliance and packaging requirements:

• 23J2R2: Select this part for applications where RoHS non-compliant components are acceptable and standard packaging is required.
• 23J2R2E: Select this part for applications requiring ROHS3 compliance or when bulk packaging is preferred for high-volume assembly operations.

Both parts are suitable for through-hole PCB assembly and deliver equivalent performance in circuits requiring 2.2 Ohm, 3W wirewound resistors with flame retardant characteristics.

Frequently Asked Questions (FAQ)

Q: Can 23J2R2E replace 23J2R2 in my circuit? A: Yes. The 23J2R2E is electrically and mechanically identical to the 23J2R2. The only differences are packaging configuration and RoHS compliance status. Substitution is valid for all electrical performance requirements.

Q: What is the difference between standard and bulk packaging? A: Standard packaging typically includes individual component packaging suitable for smaller orders and mixed-component shipments. Bulk packaging consolidates multiple units for high-volume manufacturing environments, reducing per-unit packaging material and cost.

Q: Does RoHS compliance affect circuit performance? A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical electrical characteristics and power dissipation.

Q: Are the physical dimensions identical? A: Yes. Both parts measure 0.220" Dia x 0.516" L (5.60mm x 13.10mm) and are fully interchangeable in PCB layouts designed for axial resistors.

Q: Which part should I specify for new designs? A: For new designs, specify 23J2R2E if your application or customer requirements mandate ROHS3 compliance. Otherwise, either part is acceptable based on packaging and inventory availability.
