Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 40J220 is determined by the following critical parameters:

• Resistance value: 220 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 10W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)
• Physical dimensions: 0.406" Dia x 1.902" L (exact match required)

The identified substitute part 40J220E meets all electrical and mechanical parameters. The primary distinction is packaging configuration (Bulk versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 40J220 and 40J220E are active production components with identical electrical and mechanical specifications. Selection between these parts should be based on:

• RoHS compliance requirements: The 40J220E is ROHS3 compliant, while the 40J220 is RoHS non-compliant. Applications subject to RoHS directives must use the 40J220E.
• Packaging requirements: The 40J220E is supplied in Bulk packaging, while the 40J220 uses standard packaging. Procurement workflows and inventory management practices may influence packaging selection.
• Availability: The 40J220E has higher inventory availability (1197 units versus 774 units).

Both parts are functionally interchangeable in circuit applications where the specified electrical and mechanical parameters are required.

Frequently Asked Questions (FAQ)

Q: Can the 40J220E replace the 40J220 in existing designs?

A: Yes. The 40J220E is electrically and mechanically identical to the 40J220. Both components have the same resistance value (220 Ohms), tolerance (±5%), power rating (10W), composition (Wirewound), package type (Axial), temperature coefficient (±20ppm/°C), and physical dimensions (0.406" Dia x 1.902" L). The primary differences are packaging configuration and RoHS compliance status.

Q: What is the difference between the standard packaging and Bulk packaging?

A: Packaging configuration affects order quantities, shipping methods, and inventory handling. Bulk packaging typically accommodates larger quantities per container. Both packaging types contain identical components with the same electrical and mechanical specifications.

Q: Which part should I select for RoHS-compliant applications?

A: The 40J220E is ROHS3 compliant and must be used for applications subject to RoHS directives. The 40J220 is RoHS non-compliant and is not suitable for RoHS-regulated applications.

Q: Are there any performance differences between these parts?

A: No. Both parts have identical electrical characteristics: 220 Ohm resistance, ±5% tolerance, 10W power rating, ±20ppm/°C temperature coefficient, and Wirewound composition. Performance in circuit applications is equivalent.

Q: Can I use these parts interchangeably in my PCB design?

A: Yes. Both parts are Axial package through-hole components with identical physical dimensions (0.406" Dia x 1.902" L). PCB footprints and board layouts designed for one part accommodate the other without modification.
