Key Parameters

Substitute Part Grouping Explanation

The Ohmite 40J22RE qualifies as a parametric equivalent to the 40J22R based on identical electrical and mechanical specifications:

• Resistance value: 22 Ohms (identical)
• Tolerance: ±5% (identical)
• Power rating: 10W (identical)
• Wirewound composition (identical)
• Temperature coefficient: ±20ppm/°C (identical)
• Package configuration: Axial (identical)
• Physical dimensions: 0.406" Dia x 1.902" L (identical)
• Termination count: 2 (identical)

The primary distinction between these parts is packaging format (Box versus Bulk) and RoHS compliance status. Both parts belong to the Ohmicone® 40 series and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the 40J22R and 40J22RE are functionally equivalent for circuit applications requiring 22 Ohm, 10W axial wirewound resistors. Selection between these parts should be based on:

• RoHS compliance requirements: The 40J22RE meets ROHS3 compliance, while the 40J22R is RoHS non-compliant. Applications subject to RoHS directives must use the 40J22RE.
• Packaging requirements: The 40J22R is supplied in Box packaging; the 40J22RE is supplied in Bulk packaging. Procurement specifications may dictate packaging format based on assembly and inventory management protocols.
• Inventory availability: Both parts maintain active status with adequate stock levels (941 and 1070 units respectively).

Both parts carry identical electrical performance characteristics and mechanical specifications, ensuring direct substitution without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the 40J22RE be used as a direct replacement for the 40J22R?

A: Yes. The 40J22RE is electrically and mechanically identical to the 40J22R. Both parts have 22 Ohm resistance, ±5% tolerance, 10W power rating, ±20ppm/°C temperature coefficient, and identical axial package dimensions. The primary differences are packaging format and RoHS compliance status.

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

A: Box packaging typically includes individual component packaging suitable for smaller quantity orders or applications requiring component traceability. Bulk packaging is used for higher-volume procurement and assembly operations. Both packaging formats contain the same electrical component.

Q: Which part should I select if my application requires RoHS compliance?

A: The 40J22RE is ROHS3 compliant and must be used for applications subject to RoHS directives. The 40J22R is RoHS non-compliant and is not suitable for RoHS-regulated applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 40J22R and 40J22RE have identical dimensions of 0.406" diameter by 1.902" length (10.30mm x 48.30mm). They are mechanically interchangeable in PCB layouts and through-hole applications.

Q: What is the operating temperature range for these resistors?

A: The 40J22R operates from -55°C to 275°C. The 40J22RE operating temperature range is not specified in the provided data but maintains identical temperature coefficient performance of ±20ppm/°C.
