Key Parameters

Substitute Part Grouping Explanation

The Ohmite 20JR13E qualifies as a direct equivalent substitute based on the following matching parameters:

• Resistance value: 130 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)
• Termination count: 2
• Features: Flame Retardant Coating, Safety

The primary distinction between the main part and substitute is packaging format and RoHS compliance status. The 20JR13E is supplied in bulk packaging and meets ROHS3 compliance requirements, whereas the 20JR13 is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

Both the 20JR13 and 20JR13E are active production parts from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements:

• 20JR13: Select for applications where RoHS non-compliance is acceptable or where legacy component specifications are required.
• 20JR13E: Select for applications requiring ROHS3 compliance or for new designs targeting modern regulatory standards.

Both parts are classified under ECCN EAR99 and HTSUS 8533.21.0080, with REACH Unaffected status. Packaging format differs (standard vs. bulk), which may influence procurement and inventory management decisions.

Frequently Asked Questions (FAQ)

Q: Can the 20JR13E directly replace the 20JR13 in existing designs?

A: Yes. The 20JR13E is electrically and mechanically identical to the 20JR13. Both parts feature 130 mOhms resistance, ±5% tolerance, 10W power rating, wirewound composition, and identical axial package dimensions. Direct substitution is supported without circuit modification.

Q: What is the primary difference between these two parts?

A: The main differences are RoHS compliance status and packaging format. The 20JR13E meets ROHS3 compliance requirements and is supplied in bulk packaging, while the 20JR13 is RoHS non-compliant with standard packaging.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.394" diameter by 1.858" length (10.00mm x 47.20mm), ensuring identical PCB footprint and mounting compatibility.

Q: Which part should be selected for new designs?

A: The 20JR13E is recommended for new designs due to ROHS3 compliance alignment with current regulatory requirements. The 20JR13 remains suitable for legacy or non-regulated applications.

Q: Are there any performance differences between these parts?

A: No. Both parts are identical in electrical performance, featuring the same resistance value, tolerance, power rating, and flame retardant safety features.
