Substitute Part Grouping Explanation

Substitute parts for the 45J3K0 are qualified based on matching the following critical parameters:

• Resistance value: 3 kOhms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.343" Dia x 0.937" L (8.70mm x 23.80mm)
• Termination count: 2

The substitute part 45J3K0E meets all electrical and mechanical requirements for direct substitution. Differences in packaging format (Bulk versus standard packaging) and RoHS compliance status do not affect functional equivalence in applications where these certifications are not mandated.

Parameter Comparison

Engineering Selection Recommendations

Both the 45J3K0 and 45J3K0E are Active status components from Ohmite's Ohmicone® 40 series with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

45J3K0 is suitable for applications where standard packaging is required and RoHS non-compliance is acceptable for the end application.

45J3K0E is the appropriate choice for applications requiring ROHS3 compliance or when bulk packaging format is preferred for manufacturing operations. Higher current inventory (1154 pieces) may provide supply chain advantages.

Both parts carry EAR99 export classification and are subject to the same HTSUS code (8533.21.0080).

Frequently Asked Questions (FAQ)

Q: Can 45J3K0E be used as a direct replacement for 45J3K0?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance values (3 kOhms), tolerance (±5%), power rating (5W), composition (wirewound), axial package configuration, and physical dimensions (0.343" Dia x 0.937" L). The primary differences are packaging format and RoHS compliance status.

Q: What is the difference between the packaging formats?

A: The 45J3K0 uses standard packaging, while the 45J3K0E is supplied in Bulk packaging format. This affects order quantities and handling procedures but does not impact component performance or electrical characteristics.

Q: Does RoHS compliance affect component functionality?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. The 45J3K0E (ROHS3 Compliant) and 45J3K0 (RoHS non-compliant) perform identically in circuit applications. Selection should be based on end-product regulatory requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.343" diameter by 0.937" length (8.70mm x 23.80mm) and use identical axial termination configuration with 2 leads.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Identical axial package dimensions and termination configuration ensure mechanical and electrical interchangeability in through-hole PCB layouts without design modifications.
