Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Ohmite 20JR50 are qualified based on the following electrical and mechanical parameters:

• Resistance value: 500 mOhms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Package configuration: Axial
• Physical dimensions: 0.394" Dia x 1.858" L (10.00mm x 47.20mm)
• Features: Flame retardant coating and safety construction
• Number of terminations: 2

The substitute part 20JR50E maintains identical electrical specifications and physical dimensions. The primary distinction is packaging format: the main part number 20JR50 is supplied in standard packaging, while 20JR50E is supplied in bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the 20JR50 and 20JR50E are Active status components manufactured by Ohmite within the 20 series. Selection between these parts should be based on the following criteria:

The 20JR50E offers ROHS3 compliance, making it suitable for applications subject to RoHS3 regulatory requirements. The 20JR50 is RoHS non-compliant and should be selected only when RoHS compliance is not a design constraint.

Packaging format differs between the two parts: standard packaging for 20JR50 and bulk packaging for 20JR50E. Bulk packaging is typically selected for high-volume production runs, while standard packaging is appropriate for lower-volume applications or when individual component handling is required.

Both parts are electrically and mechanically identical, with matching resistance, tolerance, power rating, composition, dimensions, and safety features.

Frequently Asked Questions (FAQ)

Q: Can 20JR50E be used as a direct replacement for 20JR50?

A: Yes. The 20JR50E is electrically and mechanically equivalent to the 20JR50. Both components have identical resistance (500 mOhms), tolerance (±5%), power rating (10W), composition (wirewound), package type (axial), and physical dimensions (0.394" Dia x 1.858" L). The primary difference is packaging format and RoHS compliance status.

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

A: Standard packaging is used for the 20JR50, while bulk packaging is used for the 20JR50E. Bulk packaging is designed for high-volume manufacturing environments where components are handled in larger quantities. Standard packaging is suitable for lower-volume applications or when individual component management is required.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance status does not affect the electrical or mechanical performance of the component. The 20JR50E is ROHS3 compliant, while the 20JR50 is RoHS non-compliant. Selection should be based on regulatory requirements applicable to the end application.

Q: Are the physical dimensions identical between 20JR50 and 20JR50E?

A: Yes. Both parts have identical dimensions of 0.394" Dia x 1.858" L (10.00mm x 47.20mm) and are supplied in axial package configuration with 2 terminations.

Q: What applications require RoHS3 compliance?

A: RoHS3 compliance is required for products sold in the European Union and other regions with equivalent regulatory frameworks. Applications subject to these regulations must use ROHS3 compliant components such as the 20JR50E.
