Substitute Part Grouping Explanation

Substitution eligibility for the 23J68R is determined by strict equivalence across the following critical parameters:

• Resistance value: 68 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±30ppm/°C
• Physical dimensions: 0.220" Dia x 0.516" L (5.60mm x 13.10mm)
• Termination count: 2
• Features: Flame Retardant Coating, Safety

The substitute part 23J68RE meets all electrical and mechanical parameters required for direct substitution. Differences in RoHS compliance status do not affect functional equivalence but may impact procurement decisions based on regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 23J68R and 23J68RE are active production parts from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements:

• Use 23J68R when RoHS non-compliant components are acceptable for the application.
• Use 23J68RE when ROHS3 compliance is required by design specifications or regulatory mandates.

Both parts carry REACH Unaffected status and are classified under ECCN EAR99 with HTSUS code 8533.21.0080.

Frequently Asked Questions (FAQ)

Q: Can 23J68RE be used as a direct replacement for 23J68R?

A: Yes. The 23J68RE is electrically and mechanically equivalent to the 23J68R. All critical parameters including resistance value, tolerance, power rating, composition, package type, and physical dimensions are identical. The primary difference is RoHS compliance status.

Q: What is the difference between 23J68R and 23J68RE?

A: The 23J68RE is ROHS3 compliant, while the 23J68R is RoHS non-compliant. All other specifications are identical. The "E" suffix in the part number indicates the RoHS3 compliant variant.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical axial package dimensions of 0.220" diameter by 0.516" length (5.60mm x 13.10mm), ensuring compatibility with existing PCB layouts and through-hole mounting patterns.

Q: What applications require the RoHS3 compliant variant?

A: Applications subject to European Union Restriction of Hazardous Substances regulations, or designs requiring RoHS3 certification for end-market compliance, should use the 23J68RE variant.

Q: Are there inventory differences between these parts?

A: Yes. The 23J68R has 754 pieces in stock, while the 23J68RE has 1213 pieces in stock. Availability may vary based on current procurement cycles.
