Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 20J3K0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 3 kOhms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Package configuration: Axial with 2 terminations
• Physical dimensions: 0.394" Dia x 1.858" L (10.00mm x 47.20mm)
• Temperature coefficient: ±30ppm/°C
• Safety features: Flame retardant coating

The substitute part 20J3K0E meets all electrical and mechanical requirements for direct substitution. Packaging differences (Bulk versus standard packaging) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 20J3K0 and 20J3K0E are Active status components suitable for direct substitution. The primary distinction is regulatory compliance: the 20J3K0E is ROHS3 compliant, while the 20J3K0 is RoHS non-compliant. For applications subject to RoHS3 requirements, the 20J3K0E is the appropriate selection. Both parts maintain identical electrical performance, mechanical dimensions, and safety certifications. Component selection should be based on applicable regulatory requirements and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can the 20J3K0E replace the 20J3K0 in existing designs?

A: Yes. The 20J3K0E is electrically and mechanically equivalent to the 20J3K0. All critical parameters including resistance, tolerance, power rating, temperature coefficient, and physical dimensions are identical. Substitution is valid for applications where RoHS3 compliance is not a requirement.

Q: What is the difference between the 20J3K0 and 20J3K0E?

A: The primary difference is RoHS compliance status. The 20J3K0E is ROHS3 compliant, while the 20J3K0 is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The 20J3K0 is supplied in standard packaging, while the 20J3K0E is supplied in Bulk packaging. Both use identical Axial package configuration with no impact on functional performance or PCB assembly compatibility.

Q: What parameters must remain constant for substitution?

A: Resistance (3 kOhms), tolerance (±5%), power rating (10W), composition (Wirewound), package type (Axial), physical dimensions (0.394" Dia x 1.858" L), temperature coefficient (±30ppm/°C), and safety features (Flame retardant coating) must all remain constant for valid substitution.

Q: Is the 20J3K0E suitable for RoHS3 regulated applications?

A: Yes. The 20J3K0E is ROHS3 compliant and is suitable for applications subject to RoHS3 requirements.
