Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Ohmite 41J2K0 are identified based on strict parametric equivalence. The following electrical and mechanical parameters must remain identical for substitution compatibility:

• Resistance value: 2 kOhms
• Tolerance: ±5%
• Power rating: 1W
• Composition: Wirewound
• Package type: Axial
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.126" Dia x 0.437" L (3.20mm x 11.10mm)
• Number of terminations: 2
• Series: Ohmicone® 40

Variations in packaging configuration (tape and reel versus bulk) and RoHS compliance status do not affect electrical or mechanical interchangeability. Both the main part and substitute maintain identical performance characteristics within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 41J2K0 and 41J2K0E are electrically and mechanically equivalent components suitable for direct substitution in axial wirewound resistor applications requiring 2 kOhms ±5% at 1W power dissipation.

The 41J2K0E offers ROHS3 compliance, making it the appropriate selection for applications subject to RoHS3 regulatory requirements. The 41J2K0 remains suitable for applications without RoHS compliance mandates.

Packaging differences (standard versus bulk) do not affect component performance or interchangeability. Selection between these parts should be based on regulatory compliance requirements and packaging format availability for procurement workflows.

Frequently Asked Questions (FAQ)

Q: Can the 41J2K0E replace the 41J2K0 in existing designs?

A: Yes. Both parts are parametrically identical in all electrical and mechanical specifications. The 41J2K0E is a direct substitute with identical resistance, tolerance, power rating, composition, package type, and physical dimensions.

Q: What is the difference between the 41J2K0 and 41J2K0E?

A: The primary differences are packaging configuration (standard versus bulk) and RoHS compliance status. The 41J2K0E is ROHS3 compliant, while the 41J2K0 is RoHS non-compliant. All electrical and mechanical parameters remain identical.

Q: Are these parts interchangeable on PCBs?

A: Yes. Both parts feature identical axial package dimensions (0.126" Dia x 0.437" L) and two terminations, ensuring mechanical and electrical interchangeability in through-hole PCB applications.

Q: Which part should I select for RoHS-regulated applications?

A: The 41J2K0E is ROHS3 compliant and is the appropriate selection for applications subject to RoHS3 regulatory requirements.

Q: Do these parts have different temperature coefficients?

A: No. Both the 41J2K0 and 41J2K0E maintain an identical temperature coefficient of ±20ppm/°C.
