Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 45J220 is determined by strict equivalence across the following critical parameters:

• Resistance value: 220 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Wirewound (exact match required)
• Package/Case: Axial (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)
• Physical dimensions: 0.343" Dia x 0.937" L (exact match required)
• Number of terminations: 2 (exact match required)

The substitute part 45J220E meets all electrical and mechanical parameters required for direct substitution. Packaging configuration differs (Bulk vs. standard packaging) but does not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 45J220 and 45J220E are electrically and mechanically equivalent for direct substitution in circuit applications. Selection between these parts should be based on the following criteria:

45J220 (Main Part): Select when standard packaging configuration is required and RoHS compliance is not a design constraint.

45J220E (Substitute): Select when ROHS3 compliance is required for the end application or when bulk packaging configuration aligns with procurement requirements. This part is the preferred choice for applications subject to RoHS3 regulatory requirements.

Both parts maintain active product status and are available in current inventory, ensuring supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can 45J220E be used as a direct replacement for 45J220?

A: Yes. The 45J220E is electrically and mechanically equivalent to the 45J220. All critical parameters including resistance, tolerance, power rating, composition, package type, and physical dimensions are identical. The primary difference is RoHS compliance status and packaging configuration.

Q: What is the difference between the packaging configurations?

A: The 45J220 uses standard packaging, while the 45J220E uses bulk packaging. Both configurations contain the same component and do not affect electrical performance or mechanical fit in circuit board applications.

Q: Which part should be selected for RoHS3-compliant applications?

A: The 45J220E is ROHS3 compliant and should be selected for applications requiring RoHS3 certification. The 45J220 is RoHS non-compliant and is not suitable for RoHS3-regulated applications.

Q: Are there any performance differences between these parts?

A: No. Both parts have identical electrical specifications: 220 Ohms resistance, ±5% tolerance, 5W power rating, ±20ppm/°C temperature coefficient, and wirewound composition. Performance in circuit applications is equivalent.

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

A: Yes. The physical dimensions (0.343" Dia x 0.937" L) and axial package type are identical, allowing direct PCB footprint compatibility and mechanical interchangeability.

Q: What inventory levels are available for each part?

A: The 45J220 has 1022 units in stock, and the 45J220E has 986 units in stock. Both parts are available for immediate procurement.
