OF68GJE Equivalent & Substitute Parts Reference

Part Overview

The OF68GJE is a 6.8 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 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 design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OF68GJE is determined by the following critical parameters:

• Resistance Value: Must be 6.8 Ohms
• Power Rating: Must be 0.5W (1/2W)
• 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
• Terminations: 2-terminal through-hole configuration
• Features: Pulse Withstanding capability

The OF68GKE qualifies as a substitute based on matching all critical parameters. The tolerance specification differs (±10% versus ±5%), which represents a relaxation of the tolerance requirement and does not prevent substitution in applications where the broader tolerance is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The OF68GKE is the manufacturer-recommended substitute for the OF68GJE. Both parts are ROHS3 compliant and maintain identical physical dimensions, power ratings, and axial package configuration. The primary difference is tolerance specification: the OF68GKE operates at ±10% tolerance compared to the OF68GJE's ±5% tolerance.

Selection between these parts depends on circuit tolerance requirements. Applications requiring ±5% tolerance precision must use the OF68GJE. Applications where ±10% tolerance is acceptable can utilize the OF68GKE, which offers greater availability (1924 pcs in stock versus 1021 pcs for the main part).

Both parts are obsolete products from the Little Demon® OF series. Current design work should evaluate modern carbon composition or thin-film resistor alternatives that offer extended product lifecycle support.

Frequently Asked Questions (FAQ)

Q: Can OF68GKE replace OF68GJE in all applications?

A: OF68GKE can replace OF68GJE only in applications where ±10% tolerance is acceptable. The OF68GKE's wider tolerance specification makes it unsuitable for circuits requiring ±5% precision.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both OF68GJE and OF68GKE share identical axial package dimensions of 0.150" diameter by 0.406" length (3.80mm x 10.30mm), ensuring mechanical compatibility in PCB layouts and through-hole mounting.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both OF68GJE and OF68GKE are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What is the difference in packaging between these parts?

A: OF68GJE is supplied in Strip packaging, while OF68GKE is supplied in Bulk packaging. This affects procurement and handling but does not impact electrical or mechanical performance.

Q: Are these parts still in production?

A: No. Both OF68GJE and OF68GKE are classified as obsolete products. For new designs, alternative resistor technologies with active production status should be evaluated.
