Substitute Part Grouping Explanation

The Ohmite 20JR10E is identified as a parametric equivalent to the 20JR10. Substitution is valid based on the following criteria:

• Identical resistance value: 100 mOhms
• Identical tolerance: ±5%
• Identical power rating: 10W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical physical dimensions: 0.394" Dia x 1.858" L (10.00mm x 47.20mm)
• Identical features: Flame Retardant Coating, Safety
• Identical number of terminations: 2
• Same manufacturer series: 20

The primary difference between the main part and substitute is packaging format (Bulk for 20JR10E versus standard for 20JR10) and compliance status (RoHS Compliant for 20JR10E versus RoHS non-compliant for 20JR10).

Parameter Comparison

Engineering Selection Recommendations

Both the 20JR10 and 20JR10E are Active status components from Ohmite's Series 20 wirewound resistor line. Selection between these parts should be based on compliance requirements:

• Select 20JR10 when RoHS non-compliant components are acceptable for the application.
• Select 20JR10E when RoHS compliance is required or mandated by design specifications or regulatory requirements.

Both parts are electrically and mechanically identical, with identical resistance, tolerance, power rating, composition, package type, and physical dimensions. The 20JR10E offers improved compliance status with RoHS certification and defined moisture sensitivity level (MSL 1 - Unlimited), making it suitable for applications with stricter environmental or regulatory constraints.

Frequently Asked Questions (FAQ)

Q: Can the 20JR10E be used as a direct replacement for the 20JR10?

A: Yes. The 20JR10E is electrically and mechanically equivalent to the 20JR10. All critical parameters including resistance, tolerance, power rating, composition, package type, and physical dimensions are identical. The primary difference is RoHS compliance status.

Q: What is the difference between the 20JR10 and 20JR10E?

A: The 20JR10E is RoHS Compliant with defined MSL 1 (Unlimited) rating, while the 20JR10 is RoHS non-compliant with Not Applicable MSL. Packaging format differs (Bulk for 20JR10E). All electrical and mechanical specifications are identical.

Q: Are there any physical dimension differences between these parts?

A: No. Both parts have identical physical dimensions of 0.394" Dia x 1.858" L (10.00mm x 47.20mm) and use the same axial package type.

Q: Which part should I select for a new design?

A: Selection depends on compliance requirements. For designs requiring RoHS compliance, select 20JR10E. For applications without RoHS requirements, either part is suitable based on availability and procurement preferences.

Q: Are both parts currently available?

A: Yes. The 20JR10 has 1046 units in stock, and the 20JR10E has 1093 units in stock.
