Ohmite 41JR10 Equivalent & Substitute Parts

Part Overview

The Ohmite 41JR10 is a 100 mOhms ±5% 1W through-hole resistor with axial wirewound construction, part of the Ohmicone® 40 series. This component is currently active in production and maintains an inventory of 837 pieces in new original condition. The 41JR10 is designed for applications requiring precision low-resistance values with 1-watt power dissipation capability in a compact axial package format.

Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when packaging requirements differ.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 41JR10 are qualified based on matching the following critical electrical and mechanical parameters:

• Resistance value: 100 mOhms
• Tolerance: ±5%
• Power rating: 1W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±90ppm/°C
• Physical dimensions: 0.126" Dia x 0.437" L (3.20mm x 11.10mm)
• Number of terminations: 2

The 41JR10E is classified as a parametric equivalent, differing only in packaging format (bulk versus standard packaging) and RoHS compliance status. All electrical specifications and mechanical dimensions remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the 41JR10 and 41JR10E are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

The 41JR10E offers ROHS3 compliance, making it suitable for applications subject to RoHS regulations. The 41JR10 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Packaging format differs between the two parts: the 41JR10 uses standard packaging while the 41JR10E is supplied in bulk format. Bulk packaging may be preferred for high-volume manufacturing operations.

Both parts carry identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications, indicating no restrictions on export or tariff treatment differences.

Frequently Asked Questions (FAQ)

Q: Can the 41JR10E be used as a direct replacement for the 41JR10?

A: Yes. The 41JR10E is electrically and mechanically identical to the 41JR10. The only differences are packaging format and RoHS compliance status. Direct substitution is possible in any application where the 41JR10 was originally specified.

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

A: Standard packaging refers to the original equipment manufacturer (OEM) packaging format, while bulk packaging consolidates multiple units in larger quantities without individual component packaging. Bulk packaging is typically used for high-volume manufacturing operations to reduce packaging material and handling costs.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to the materials and manufacturing processes used, not to the electrical or thermal characteristics of the component. Both the 41JR10 and 41JR10E deliver identical electrical performance.

Q: Are there any thermal or frequency limitations for these axial wirewound resistors?

A: The temperature coefficient of ±90ppm/°C applies across the operating range. No specific frequency limitations are provided in the component specifications.

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

A: Both parts are active production components from Ohmite. Failure rate data is not provided in the available specifications. Consult Ohmite technical documentation or contact the manufacturer for high-reliability application requirements.
