OD39GJ Equivalent & Substitute Parts

Part Overview

The OD39GJ is a 3.9 Ohms ±5% 0.25W (1/4W) through-hole resistor with axial leads manufactured by Ohmite as part of the Little Demon® OD series. This carbon composition resistor features pulse withstanding capability and is packaged in axial configuration with 2.50mm diameter and 7.00mm length dimensions.

The OD39GJ is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for applications utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OD39GJ is based on electrical and mechanical parameter equivalence within the Little Demon® OD series. The substitute part OD39GJE maintains identical specifications across all critical parameters:

• Resistance value: 3.9 Ohms
• Tolerance: ±5%
• Power rating: 0.25W (1/4W)
• Composition: Carbon Composition
• Package configuration: Axial
• Physical dimensions: 0.098" Dia x 0.276" L (2.50mm x 7.00mm)
• Pulse withstanding feature: Present
• Termination count: 2
• Moisture sensitivity level: 1 (Unlimited)

The primary distinction between these parts is product status and packaging format, with OD39GJE representing the active production equivalent available in strip packaging.

Parameter Comparison

Engineering Selection Recommendations

The OD39GJE is the direct substitute for the obsolete OD39GJ. Both components are manufactured by Ohmite within the Little Demon® OD series and share identical electrical and mechanical specifications. The OD39GJE is the recommended selection for new designs and ongoing production requirements due to its active product status and ROHS3 compliance certification.

For applications where RoHS compliance is not a requirement, the OD39GJ remains functionally equivalent to OD39GJE. However, OD39GJE availability in strip packaging format provides superior supply chain accessibility compared to the obsolete OD39GJ.

Frequently Asked Questions (FAQ)

Q: Can OD39GJE directly replace OD39GJ in existing designs?

A: Yes. The OD39GJE is electrically and mechanically equivalent to the OD39GJ. Both components feature identical resistance (3.9 Ohms), tolerance (±5%), power rating (0.25W), composition (carbon composition), axial package configuration, and physical dimensions (0.098" Dia x 0.276" L). Direct substitution is supported without circuit modification.

Q: What is the primary difference between OD39GJ and OD39GJE?

A: The OD39GJ is classified as obsolete, while OD39GJE is active production. Additionally, OD39GJE is ROHS3 compliant, whereas OD39GJ is RoHS non-compliant. Packaging format differs, with OD39GJE supplied in strip configuration.

Q: Are there any compatibility concerns with axial package dimensions?

A: No. Both parts maintain identical physical dimensions of 0.098" Dia x 0.276" L (2.50mm x 7.00mm), ensuring mechanical compatibility with existing PCB layouts and through-hole mounting configurations.

Q: Does moisture sensitivity affect substitution suitability?

A: No. Both OD39GJ and OD39GJE share identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity constraints for either component.

Q: Is OD39GJE suitable for applications requiring pulse withstanding capability?

A: Yes. The OD39GJE retains the pulse withstanding feature present in the OD39GJ, maintaining functional equivalence for applications requiring this specification.
