Ohmite 41J2R0 Equivalent & Substitute Parts

Part Overview

The Ohmite 41J2R0 is a 2 Ohm, 1W axial wirewound resistor from the Ohmicone® 40 series. This through-hole component is designed for applications requiring precision resistance with wirewound construction and tight tolerance specifications. The part is currently active in production. Substitute parts may be required due to packaging preferences, compliance requirements, or inventory availability across different distribution channels.

Key Parameters

Substitute Part Grouping Explanation

The Ohmite 41J2R0E qualifies as a parametric equivalent based on identical electrical and mechanical specifications. Substitution is valid when the following criteria are met:

• Resistance value: 2 Ohms
• Tolerance: ±5%
• Power rating: 1W
• Composition: Wirewound
• Package: Axial
• Temperature coefficient: ±50ppm/°C
• Physical dimensions: 0.126" Dia x 0.437" L (3.20mm x 11.10mm)
• Termination count: 2

The primary difference between the main part and substitute is packaging format (tape/reel versus bulk) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 41J2R0 and 41J2R0E are active production parts from Ohmite's Ohmicone® 40 series with identical electrical and mechanical performance. Selection between these parts should be based on:

• Packaging requirements: The 41J2R0 is supplied in tape/reel format, while the 41J2R0E is supplied in bulk packaging.
• Compliance requirements: The 41J2R0E carries ROHS3 compliance certification, whereas the 41J2R0 is RoHS non-compliant. Applications subject to RoHS directives must use the 41J2R0E.
• Both parts share identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can 41J2R0E be used as a direct replacement for 41J2R0?

A: Yes. Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, temperature coefficient, and physical dimensions. The difference is packaging format and RoHS compliance status.

Q: What is the difference between tape/reel and bulk packaging?

A: Tape/reel packaging (41J2R0) is used for automated assembly processes, while bulk packaging (41J2R0E) is used for manual assembly or smaller quantity applications. The components themselves are identical.

Q: Which part should I specify for RoHS-compliant applications?

A: Specify 41J2R0E, which carries ROHS3 compliance certification. The 41J2R0 is RoHS non-compliant and should not be used in applications requiring RoHS compliance.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts measure 0.126" diameter by 0.437" length (3.20mm x 11.10mm) and are housed in identical axial packages.

Q: What is the temperature coefficient specification?

A: Both parts have a temperature coefficient of ±50ppm/°C, ensuring stable resistance performance across the operating temperature range.
