Substitute Part Grouping Explanation

Substitution eligibility for the 45J22RE is determined by three critical parameters: resistance value, power rating, and package configuration. All identified substitutes maintain the 22 Ohms resistance and 5W power rating in axial package format, ensuring mechanical and electrical compatibility.

The substitute parts are categorized as follows:

Parametric Equivalent (45J22R): Identical electrical specifications (22 Ohms ±5%, 5W) and mechanical dimensions. Differs in packaging format (Bulk vs. Box) and RoHS compliance status.

Upgrade Substitute (45F22RE): Maintains 22 Ohms resistance and 5W power rating with improved tolerance specification (±1% vs. ±5%). Identical mechanical dimensions and axial package configuration. Provides enhanced precision for applications requiring tighter tolerance control.

Parameter Comparison

Engineering Selection Recommendations

45J22RE (Original Specification): Select this part when RoHS compliance is mandatory and standard ±5% tolerance meets circuit requirements. Active product status with highest inventory availability (782 units) supports supply chain continuity.

45J22R (Parametric Equivalent): This substitute provides identical electrical and mechanical performance with equivalent inventory levels (685 units). Selection is appropriate only when RoHS compliance is not a design requirement, as this part carries non-compliant status.

45F22RE (Upgrade Substitute): This part is suitable for applications requiring improved tolerance control (±1% vs. ±5%) while maintaining all other specifications. RoHS compliance and full operating temperature range specification (-55°C ~ 275°C) align with the original part. Inventory availability (710 units) supports direct substitution.

Frequently Asked Questions (FAQ)

Q: Can 45J22R be used as a direct replacement for 45J22RE?

A: Electrical and mechanical compatibility is confirmed. Both parts share identical resistance (22 Ohms), tolerance (±5%), power rating (5W), and axial package dimensions (0.343" Dia x 0.937" L). The primary difference is packaging format (Bulk vs. Box) and RoHS compliance status. Selection depends on regulatory requirements for your application.

Q: What is the advantage of using 45F22RE over 45J22RE?

A: The 45F22RE provides tighter tolerance specification (±1% vs. ±5%) while maintaining identical power rating, resistance value, and mechanical dimensions. This upgrade is beneficial for precision circuits where component value accuracy directly impacts performance. Both parts are RoHS compliant with equivalent operating temperature ranges.

Q: Are all substitute parts mechanically interchangeable?

A: Yes. All three parts (45J22RE, 45J22R, and 45F22RE) share identical axial package dimensions (0.343" Dia x 0.937" L / 8.70mm x 23.80mm) and two-termination configuration, ensuring direct mechanical compatibility in through-hole applications.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Box vs. Bulk) is a supply and handling specification only. Electrical characteristics remain identical between 45J22RE and 45J22R regardless of packaging configuration.

Q: Which part should be selected for new designs?

A: For new designs, 45F22RE is recommended when tolerance precision is beneficial. For existing designs or applications where ±5% tolerance is acceptable, 45J22RE maintains compatibility with established specifications. Both parts carry RoHS compliance and active product status.
