OF361JE Equivalent & Substitute Parts

Part Overview

The OF361JE is a 360 Ohms ±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 housed in a standard axial package measuring 0.150" diameter by 0.406" length. The product is classified as obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OF361JE is determined by the following critical parameters:

• Resistance Value: The substitute must fall within the acceptable resistance range for the application. The OF361JE specifies 360 Ohms at ±5% tolerance.
• Power Rating: The substitute must support at least 0.5W (1/2W) continuous power dissipation.
• Package Type: The substitute must use axial through-hole packaging with compatible physical dimensions (0.150" diameter x 0.406" length).
• Composition: Carbon composition construction maintains consistency with the original design.
• Electrical Characteristics: Pulse withstanding capability and two-terminal configuration must be preserved.
• Compliance: RoHS3 compliance and MSL 1 rating ensure regulatory and environmental compatibility.

The OF331KE qualifies as a substitute based on matching package geometry, power rating, composition, and compliance certifications. The resistance value differs (330 Ohms vs. 360 Ohms), representing a 8.3% deviation from the original specification, which falls within acceptable tolerance margins for many circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The OF331KE serves as the manufacturer-recommended substitute for the OF361JE. Both components share identical physical packaging, power rating, composition type, and compliance certifications. The primary distinction lies in resistance value and tolerance specification. The OF331KE maintains full RoHS3 compliance and MSL 1 rating, ensuring compatibility with modern manufacturing and environmental standards. Both components are classified as obsolete, indicating limited availability through standard distribution channels. Selection between these parts should be based on circuit-specific resistance requirements and tolerance margins acceptable to the application design.

Frequently Asked Questions (FAQ)

Q: Can the OF331KE directly replace the OF361JE in all applications?

A: Direct replacement depends on circuit tolerance requirements. The OF331KE provides 330 Ohms resistance compared to the OF361JE's 360 Ohms, representing an 8.3% difference. Applications with strict resistance specifications may require circuit analysis to confirm acceptability.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the OF361JE and OF331KE share identical axial package dimensions of 0.150" diameter by 0.406" length (3.80mm x 10.30mm), ensuring mechanical compatibility in through-hole PCB layouts.

Q: What is the significance of the tolerance difference between ±5% and ±10%?

A: The OF361JE specifies ±5% tolerance, providing tighter resistance accuracy. The OF331KE specifies ±10% tolerance, allowing greater variation from the nominal 330 Ohm value. Circuit designs requiring precise resistance values should account for this difference.

Q: Are both parts RoHS compliant?

A: Yes. Both the OF361JE and OF331KE are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.

Q: Why are both components classified as obsolete?

A: Obsolete status indicates these components are no longer in active production. Both parts remain available through existing inventory channels but should not be specified for new designs requiring long-term component availability.
