OD221JE Equivalent & Substitute Parts

Part Overview

The OD221JE is a 220 Ohm ±5% 1/4W through-hole axial resistor manufactured by Ohmite as part of the Little Demon® OD series. This carbon composition resistor features pulse withstanding capability and is designed for axial lead applications in electronic circuits. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OD221JE is determined by the following critical parameters:

• Resistance Value: Must be 220 Ohms
• Power Rating: Must be 0.25W (1/4W)
• Package Type: Must be Axial with matching physical dimensions (0.098" Dia x 0.276" L)
• Composition: Carbon Composition
• Number of Terminations: 2-terminal configuration
• Compliance: ROHS3 Compliant

The OD221KE qualifies as a substitute based on matching all critical parameters. The tolerance difference (±10% versus ±5%) represents a relaxation of the tolerance specification, which is acceptable in applications where the tighter tolerance of the original part is not functionally required.

Parameter Comparison

Engineering Selection Recommendations

The OD221KE is a direct substitute for the OD221JE based on identical resistance value, power rating, physical dimensions, and package configuration. Both components are ROHS3 compliant and share the same moisture sensitivity classification. The primary difference is the tolerance specification: the OD221KE operates at ±10% tolerance compared to the OD221JE's ±5% tolerance.

Selection of the OD221KE should be based on circuit tolerance requirements. Applications requiring the tighter ±5% tolerance specification of the original OD221JE may require evaluation of the relaxed tolerance impact on circuit performance. Both parts maintain identical compliance certifications and physical compatibility for through-hole axial mounting.

Frequently Asked Questions (FAQ)

Q: Can the OD221KE be used as a direct replacement for the OD221JE?

A: Yes, the OD221KE is a direct substitute. Both components share identical resistance values, power ratings, physical dimensions, and axial package configuration. The components are mechanically and electrically compatible for through-hole mounting applications.

Q: What is the difference between the OD221JE and OD221KE?

A: The primary difference is tolerance specification. The OD221JE operates at ±5% tolerance, while the OD221KE operates at ±10% tolerance. All other electrical and mechanical parameters are identical.

Q: Are both parts ROHS3 compliant?

A: Yes, both the OD221JE and OD221KE are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Do these parts have the same physical dimensions?

A: Yes, both components have identical dimensions of 0.098" Dia x 0.276" L (2.50mm x 7.00mm) and are compatible with standard axial lead through-hole PCB layouts.

Q: What should I consider when selecting between these parts?

A: Evaluate your circuit's tolerance requirements. If the application requires ±5% tolerance accuracy, the OD221JE specification must be maintained. If tolerance relaxation to ±10% is acceptable for circuit function, the OD221KE is a suitable substitute.
