Ohmite 40J22RE Equivalent & Substitute Parts

Part Overview

The Ohmite 40J22RE is a 22 Ohms ±5% 10W through-hole resistor with axial wirewound construction, part of the Ohmicone® 40 series. This component is actively manufactured and stocked with 1149 units available. The 40J22RE is packaged in a box configuration and is RoHS compliant, making it suitable for applications requiring environmental compliance. Substitute parts are identified when packaging requirements differ, inventory constraints exist, or alternative compliance certifications are needed while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 40J22RE is determined by matching the following critical parameters: resistance value (22 Ohms), tolerance (±5%), power rating (10W), composition (wirewound), package type (axial), temperature coefficient (±20ppm/°C), and physical dimensions (0.406" Dia × 1.902" L). The primary substitute identified is the Ohmite 40J22R, which maintains identical electrical and mechanical specifications. The distinction between these parts lies in packaging configuration (box versus bulk) and RoHS compliance status, not in functional performance or electrical characteristics.

Engineering Selection Recommendations

The 40J22RE is the primary selection for applications requiring RoHS compliance certification. Both the 40J22RE and 40J22R are active products from Ohmite with identical electrical performance and mechanical compatibility. Selection between these parts depends on packaging requirements and regulatory compliance needs. The 40J22RE in box packaging is appropriate for controlled component distribution and traceability requirements. The 40J22R in bulk packaging serves applications where RoHS non-compliance is acceptable and bulk component handling is standard practice. Both parts share the same ECCN (EAR99) and HTSUS classification (8533.21.0080).

Frequently Asked Questions (FAQ)

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

A: The 40J22R provides electrical and mechanical equivalence to the 40J22RE. Both components have identical resistance (22 Ohms), tolerance (±5%), power rating (10W), temperature coefficient (±20ppm/°C), and physical dimensions (0.406" Dia × 1.902" L). The primary difference is RoHS compliance status and packaging configuration. Selection depends on whether RoHS compliance is required for your application.

Q: What is the difference between box and bulk packaging?

A: Box packaging (40J22RE) provides individual component packaging suitable for controlled distribution and traceability. Bulk packaging (40J22R) supplies components in larger quantities without individual packaging, typically used in high-volume manufacturing environments where component tracking occurs at the assembly level.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 40J22RE and 40J22R have identical axial dimensions of 0.406" diameter by 1.902" length (10.30mm × 48.30mm), ensuring mechanical compatibility in PCB layouts and through-hole applications.

Q: What does RoHS compliance mean for component selection?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the component meets environmental regulations restricting specific hazardous materials. The 40J22RE is RoHS compliant; the 40J22R is not. Applications subject to RoHS regulations or customer requirements must use the 40J22RE.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Both parts operate across the same temperature range and share identical temperature coefficients (±20ppm/°C). The operating temperature range extends from -55°C to 275°C for the 40J22RE. Operating temperature data for the 40J22R was not provided in the specification. Verify operating temperature limits for the 40J22R if high-temperature operation is required.
