OF222J Equivalent & Substitute Parts

Part Overview

The OF222J is a 2.2 kOhms ±5% 0.5W through-hole resistor manufactured by Ohmite as part of the Little Demon® OF series. This axial carbon composition resistor features pulse withstanding capability and is designed for applications requiring reliable fixed resistance in compact form factors. The OF222J is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OF222J is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance Value: 2.2 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 0.5W / 1/2W (exact match required)
• Composition: Carbon Composition (exact match required)
• Package Configuration: Axial through-hole (exact match required)
• Physical Dimensions: 0.150" Dia x 0.406" L (exact match required)
• Termination Count: 2 (exact match required)
• Features: Pulse Withstanding capability (exact match required)

The OF222JE qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. Packaging format differences (bulk versus strip) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The OF222JE serves as the direct functional equivalent to the OF222J. Both components share identical electrical specifications (2.2 kOhms ±5%, 0.5W) and mechanical form factors (axial, 0.150" Dia x 0.406" L). The primary distinction is regulatory compliance: the OF222JE achieves ROHS3 compliance, whereas the OF222J is RoHS non-compliant. For applications subject to RoHS requirements or environmental regulations, the OF222JE is the appropriate selection. Both components are classified as obsolete; component availability should be verified with authorized distributors prior to procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can OF222JE replace OF222J in existing designs? A: Yes. The OF222JE is electrically and mechanically equivalent to the OF222J. Both components feature identical resistance (2.2 kOhms ±5%), power rating (0.5W), composition (carbon composition), and axial package dimensions (0.150" Dia x 0.406" L). Direct substitution is functionally valid.

Q: What is the difference between OF222J and OF222JE? A: The components are electrically and mechanically identical. The primary difference is packaging format (bulk versus strip) and regulatory compliance status. The OF222JE is ROHS3 compliant, while the OF222J is RoHS non-compliant.

Q: Are there any compatibility concerns with the axial package format? A: No. Both the OF222J and OF222JE utilize identical axial through-hole packaging with 2 terminations and matching physical dimensions. PCB footprints and lead spacing are equivalent.

Q: What should be considered when sourcing these obsolete components? A: Both the OF222J and OF222JE are classified as obsolete. Availability is limited to existing inventory held by authorized distributors. Verify stock status and lead times before finalizing procurement. For new designs, consider modern carbon composition or thin-film resistor alternatives with equivalent electrical specifications.

Q: Does the RoHS compliance difference affect electrical performance? A: No. RoHS compliance status reflects manufacturing process and material composition standards, not electrical performance. Both components deliver identical resistance, tolerance, and power handling characteristics.
