OD222JE Equivalent & Substitute Parts

Part Overview

The OD222JE is a 2.2 kOhms ±5% 0.25W through-hole resistor manufactured by Ohmite as part of the Little Demon® OD series. This carbon composition axial resistor features pulse withstanding capability and is designed for applications requiring reliable performance in compact form factors. 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 OD222JE is determined by the following critical parameters:

• Resistance Value: 2.2 kOhms (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Package Type: Axial through-hole configuration (exact match required)
• Composition: Carbon composition construction (exact match required)
• Physical Dimensions: 0.098" Dia x 0.276" L (exact match required)
• Pulse Withstanding Feature: Required for equivalent functionality
• RoHS Compliance: ROHS3 Compliant (maintained)

The OD222KE qualifies as a direct substitute based on matching all critical parameters. The tolerance specification differs (±10% versus ±5%), which represents a relaxation of the tolerance requirement and is acceptable for applications where the original ±5% tolerance is not a functional constraint.

Parameter Comparison

Engineering Selection Recommendations

The OD222KE is a qualified substitute for the OD222JE based on electrical and mechanical equivalence. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental consistency. The tolerance difference (±10% versus ±5%) represents the only specification variance and should be evaluated against circuit design requirements. Applications with strict tolerance requirements may require circuit-level compensation or alternative component selection strategies. Both parts are classified as obsolete, indicating limited future availability; procurement planning should account for this status.

Frequently Asked Questions (FAQ)

Q: Can the OD222KE replace the OD222JE in all applications? A: The OD222KE is electrically and mechanically equivalent to the OD222JE. The tolerance specification is relaxed from ±5% to ±10%. Substitution is valid for applications where the ±10% tolerance meets circuit requirements. Applications with strict tolerance specifications require design review.

Q: What is the significance of the tolerance difference between these parts? A: The OD222JE specifies ±5% tolerance, while the OD222KE specifies ±10% tolerance. This means the OD222KE has a wider acceptable resistance range. For circuits sensitive to resistance variation, the original ±5% specification may be required.

Q: Are both parts physically identical? A: Yes. Both the OD222JE and OD222KE share identical physical dimensions (0.098" Dia x 0.276" L), package type (axial), and form factor. They are mechanically interchangeable in PCB layouts and through-hole applications.

Q: What does "pulse withstanding" mean for these resistors? A: Pulse withstanding indicates these carbon composition resistors are designed to tolerate transient overvoltage or overcurrent pulses without failure. This capability is maintained in both the main part and substitute.

Q: Are there RoHS compliance concerns with substitution? A: No. Both the OD222JE and OD222KE are ROHS3 compliant, ensuring equivalent environmental and regulatory status.

Q: Why are both parts classified as obsolete? A: Obsolete status indicates these parts are no longer in active production. Substitution between OD222JE and OD222KE provides continuity for legacy system support, but long-term availability is limited for both variants.
