OF47GJE Equivalent & Substitute Parts Reference

Part Overview

The OF47GJE is a 4.7 Ohm, ±5% tolerance, 0.5W (1/2W) through-hole resistor manufactured by Ohmite in the Little Demon® OF series. This axial carbon composition resistor features pulse withstanding capability and is packaged in an axial configuration with 0.150" diameter and 0.406" length (3.80mm x 10.30mm).

The OF47GJE is classified as obsolete. Identifying equivalent and substitute parts is necessary to support ongoing maintenance, repair, and redesign activities for legacy equipment and systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OF47GJE is determined by the following critical parameters:

• Resistance Value: Must be 4.7 Ohms
• Power Rating: Must be 0.5W (1/2W) or greater
• Package Type: Must be Axial configuration
• Physical Dimensions: Must match 0.150" Dia x 0.406" L (3.80mm x 10.30mm)
• Composition: Carbon Composition
• Number of Terminations: Must be 2
• Compliance: ROHS3 Compliant, MSL 1

The OF47GKE qualifies as a substitute part. While it carries a relaxed tolerance specification of ±10% compared to the OF47GJE's ±5%, it maintains identical resistance value, power rating, physical dimensions, composition, and compliance certifications. Both parts are manufactured by Ohmite in the Little Demon® OF series and share the same axial package configuration.

Parameter Comparison

Engineering Selection Recommendations

The OF47GKE is the manufacturer-recommended substitute for the OF47GJE. Both components are obsolete products from Ohmite's Little Demon® OF series and maintain full ROHS3 compliance with MSL 1 rating.

The primary difference between these parts is tolerance specification. The OF47GJE provides ±5% tolerance, while the OF47GKE provides ±10% tolerance. Selection between these parts should be based on circuit tolerance requirements. Applications requiring tighter resistance tolerance specifications must use the OF47GJE where available. Applications with tolerance margins accommodating ±10% variation may utilize the OF47GKE.

Both parts share identical physical dimensions, power ratings, composition, and termination configuration, ensuring mechanical and electrical compatibility in axial through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can OF47GKE replace OF47GJE in all applications?

A: The OF47GKE can replace the OF47GJE in applications where the circuit design accommodates ±10% resistance tolerance. If the original design requires ±5% tolerance, the OF47GKE may not be suitable without circuit re-evaluation.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both OF47GJE and OF47GKE share identical axial package dimensions of 0.150" diameter by 0.406" length (3.80mm x 10.30mm), ensuring identical PCB footprint and mounting compatibility.

Q: Do both parts meet current compliance standards?

A: Both OF47GJE and OF47GKE are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, meeting current regulatory requirements for electronic component use.

Q: What is the key difference between these substitute parts?

A: The primary difference is tolerance specification. OF47GJE carries ±5% tolerance while OF47GKE carries ±10% tolerance. All other electrical and mechanical parameters remain identical.

Q: Are both parts still in production?

A: Both OF47GJE and OF47GKE are classified as obsolete products. Availability is limited to existing inventory stocks.
