OF24GJE Equivalent & Substitute Parts

Part Overview

The OF24GJE is a 2.4 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 packaged in an axial configuration with 0.150" diameter and 0.406" length dimensions. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing circuit maintenance and new design implementations where this specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OF24GJE is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value within acceptable circuit tolerance
• Power rating equal to or greater than 0.5W
• Axial package configuration matching physical footprint requirements
• Carbon composition construction maintaining pulse withstanding characteristics
• RoHS3 compliance for regulatory alignment

The OF22GKE qualifies as a substitute based on matching power rating (0.5W), package type (axial), physical dimensions (0.150" Dia x 0.406" L), composition (carbon composition), and compliance certifications. The resistance value differs from 2.4 Ohms to 2.2 Ohms, with tolerance widening from ±5% to ±10%, requiring circuit-level validation that this 8.3% nominal resistance reduction and increased tolerance remain within acceptable operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the OF24GJE and OF22GKE are obsolete products within the Ohmite Little Demon® OF series. Selection between these parts depends on circuit tolerance requirements and resistance value criticality. The OF24GJE provides tighter tolerance control at ±5%, while the OF22GKE offers broader tolerance at ±10% with a 2.2 Ohm nominal value. Both parts maintain identical power ratings, physical dimensions, axial packaging, and RoHS3 compliance, ensuring mechanical and regulatory compatibility. The 0.2 Ohm resistance difference represents an 8.3% nominal reduction, which must be evaluated against specific circuit performance requirements before implementation.

Frequently Asked Questions (FAQ)

Q: Can OF22GKE directly replace OF24GJE in all applications?

A: Direct replacement depends on circuit tolerance requirements. The OF22GKE has a lower nominal resistance (2.2 Ohms vs. 2.4 Ohms) and wider tolerance (±10% vs. ±5%). Applications requiring precise 2.4 Ohm values or tighter tolerance control may not accept this substitute without circuit redesign or performance validation.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both OF24GJE and OF22GKE share identical physical dimensions of 0.150" diameter by 0.406" length (3.80mm x 10.30mm), ensuring mechanical compatibility in axial through-hole applications.

Q: Do both parts meet current regulatory requirements?

A: Both parts are ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited), meeting current regulatory standards for electronic component use.

Q: What is the maximum resistance variation when using OF22GKE as a substitute?

A: The OF22GKE nominal value is 2.2 Ohms with ±10% tolerance, resulting in a range of 1.98 to 2.42 Ohms. This overlaps with the OF24GJE range (2.28 to 2.52 Ohms) only in the upper tolerance band of the substitute part.

Q: Are both parts still in production?

A: No. Both OF24GJE and OF22GKE are classified as obsolete products. Availability is limited to existing inventory from authorized distributors.
