OF22GJE Equivalent & Substitute Parts Reference

Part Overview

The OF22GJE is a 2.2 Ohm ±5% 0.5W through-hole axial resistor manufactured by Ohmite as part of the Little Demon® OF series. This carbon composition resistor features pulse withstanding capability and is designed for axial package applications. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OF22GJE is determined by the following critical parameters:

• Resistance Value: Must be 2.2 Ohms
• Power Rating: Must be 0.5W (1/2W)
• Package Type: Must be Axial
• Physical Dimensions: Must match 0.150" Dia x 0.406" L (3.80mm x 10.30mm)
• Composition: Carbon Composition
• Features: Pulse Withstanding capability

The tolerance specification (±5% for the main part) may be relaxed to ±10% in substitute parts when the application circuit design permits wider tolerance margins. All substitute parts must maintain identical resistance value, power rating, package configuration, and physical dimensions to ensure direct replacement compatibility.

Parameter Comparison

Engineering Selection Recommendations

The OF22GKE serves as the manufacturer-recommended substitute for the OF22GJE. Both parts are manufactured by Ohmite within the Little Demon® OF series and share identical physical dimensions, power ratings, composition, and pulse withstanding features. The primary difference is tolerance specification: OF22GKE operates at ±10% tolerance compared to the ±5% tolerance of OF22GJE.

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental consistency. Selection between these parts depends on circuit tolerance requirements. Applications requiring tighter tolerance control should specify OF22GJE where available; applications with wider tolerance margins may utilize OF22GKE as a direct replacement.

Frequently Asked Questions (FAQ)

Q: Can OF22GKE replace OF22GJE in all applications?

A: OF22GKE is electrically and mechanically compatible with OF22GJE. The tolerance difference (±10% versus ±5%) must be evaluated against circuit design specifications. If the application circuit design accommodates ±10% tolerance, OF22GKE provides direct replacement functionality.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both OF22GJE and OF22GKE share identical axial package dimensions of 0.150" Dia x 0.406" L (3.80mm x 10.30mm), ensuring mechanical compatibility in PCB layouts and through-hole applications.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring equivalent environmental and regulatory compliance for applications requiring these certifications.

Q: What is the significance of the tolerance difference?

A: Tolerance specification defines the acceptable resistance value range. OF22GJE guarantees 2.2 Ohms ±5% (2.09–2.31 Ohms), while OF22GKE guarantees 2.2 Ohms ±10% (1.98–2.42 Ohms). Circuit designs must accommodate the wider tolerance range of OF22GKE if used as a substitute.

Q: Are both parts still in production?

A: Both OF22GJE and OF22GKE are classified as obsolete. Component selection should prioritize available inventory from authorized distributors.
