Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 23J450 is determined by strict equivalence across the following critical parameters:

• Resistance value: 450 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Physical dimensions: 0.220" Dia x 0.516" L (5.60mm x 13.10mm)
• Temperature coefficient: ±30ppm/°C
• Termination count: 2

The 23J450E qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction between these part numbers relates to packaging format and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 23J450 and 23J450E are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these part numbers should be based on the following criteria:

The 23J450E is the preferred choice for applications subject to RoHS3 compliance requirements, as it meets ROHS3 standards while maintaining full electrical and mechanical equivalence to the 23J450.

The 23J450 remains suitable for applications where RoHS compliance is not mandated and standard packaging is acceptable.

Both components carry identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications, indicating equivalent regulatory treatment for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Are the 23J450 and 23J450E electrically identical?

A: Yes. Both components feature 450 Ohm resistance with ±5% tolerance, 3W power rating, ±30ppm/°C temperature coefficient, and wirewound composition. Electrical performance is equivalent.

Q: What is the difference between these part numbers?

A: The primary differences are packaging format (standard versus bulk) and RoHS compliance status. The 23J450E is ROHS3 compliant, while the 23J450 is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Can I use the 23J450E as a direct replacement for the 23J450?

A: Yes. The 23J450E is a direct substitute with identical axial package dimensions (0.220" Dia x 0.516" L), termination configuration, and electrical specifications. No circuit modifications are required.

Q: Which part should I specify for new designs?

A: For new designs subject to RoHS3 requirements, specify the 23J450E. For applications without RoHS mandates, either part number is acceptable based on availability and packaging requirements.

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

A: No. Both components operate across the same temperature coefficient range (±30ppm/°C) and feature identical flame retardant coating and safety characteristics.
