Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 22J56R is determined by strict equivalence across the following critical parameters:

• Resistance value: 56 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±30ppm/°C (exact match required)
• Features: Flame retardant coating and safety characteristics (exact match required)
• Physical dimensions: 0.220" Dia x 0.421" L (exact match required)

The substitute part 22J56RE meets all electrical and mechanical parameters identically to the main part. Packaging configuration differs (Bulk versus standard packaging), which does not affect functional equivalence or circuit performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 22J56R and 22J56RE are electrically and mechanically equivalent for circuit applications. Selection between these parts is determined by regulatory and procurement requirements:

The 22J56R maintains RoHS non-compliant status, suitable for applications where legacy component specifications are required or where RoHS compliance is not mandated.

The 22J56RE achieves ROHS3 compliance, required for applications subject to European Union Restriction of Hazardous Substances regulations or customer specifications mandating RoHS3 certification.

Packaging configuration (standard versus Bulk) does not affect electrical performance or circuit compatibility. Selection is based on procurement quantity requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can 22J56RE be used as a direct replacement for 22J56R in existing designs?

A: Yes. The 22J56RE is electrically and mechanically equivalent to the 22J56R. All critical parameters including resistance value, tolerance, power rating, composition, package type, and physical dimensions are identical. Direct substitution in circuit designs is supported without modification.

Q: What is the difference between the 22J56R and 22J56RE?

A: The primary differences are packaging configuration (standard versus Bulk) and RoHS compliance status (non-compliant versus ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Does the Bulk packaging of 22J56RE affect circuit performance?

A: No. Packaging configuration does not affect electrical performance, thermal characteristics, or circuit compatibility. The component functions identically regardless of packaging type.

Q: Which part should be selected for RoHS-compliant applications?

A: The 22J56RE is ROHS3 compliant and is the appropriate selection for applications requiring RoHS compliance certification or customer specifications mandating RoHS3 status.

Q: Are the physical dimensions identical between 22J56R and 22J56RE?

A: Yes. Both parts measure 0.220" Dia x 0.421" L (5.60mm x 10.70mm) and are compatible with identical PCB layouts and through-hole mounting specifications.

Q: What is the temperature coefficient specification for these resistors?

A: Both the 22J56R and 22J56RE have a temperature coefficient of ±30ppm/°C, indicating stable resistance performance across the operating temperature range.
