OF513JE Equivalent & Substitute Parts

Part Overview

The OF513JE is a 51 kOhms ±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 designed for axial lead configuration. The product is classified as obsolete, making identification of compatible substitute components essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OF513JE is determined by the following critical parameters:

• Resistance Value: The substitute must maintain the 51 kOhms nominal value within acceptable circuit tolerance margins
• Power Rating: The substitute must support the 0.5W (1/2W) power dissipation requirement
• Package Configuration: The substitute must use axial lead through-hole configuration with compatible physical dimensions
• Composition Type: Carbon composition construction ensures consistency with original design specifications
• Electrical Characteristics: Pulse withstanding capability and RoHS3 compliance are required for equivalent functionality

The OF473KE is identified as a manufacturer-recommended substitute. While this part differs in resistance value (47 kOhms) and tolerance (±10%), it maintains compatibility across power rating, package type, physical dimensions, composition, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The OF473KE serves as the manufacturer-recommended substitute for the obsolete OF513JE. Both components are ROHS3 compliant and maintain identical physical dimensions, power ratings, and moisture sensitivity classifications. The substitution is valid for applications where the 4 kOhm resistance difference (51 kOhms to 47 kOhms) and increased tolerance (±5% to ±10%) fall within circuit design specifications. Both parts retain pulse withstanding capability and carbon composition construction, ensuring functional equivalence in legacy system applications.

Frequently Asked Questions (FAQ)

Q: Can OF473KE be used as a direct replacement for OF513JE?

A: The OF473KE is the manufacturer-recommended substitute. Compatibility depends on circuit tolerance requirements. The 4 kOhm resistance difference and ±10% tolerance of the OF473KE must be evaluated against the original ±5% tolerance specification of the OF513JE.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both OF513JE and OF473KE share identical axial package dimensions of 0.150" Dia x 0.406" L (3.80mm x 10.30mm), ensuring mechanical compatibility in through-hole PCB applications.

Q: Do both parts meet current compliance requirements?

A: Both OF513JE and OF473KE are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory standards.

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

A: The primary differences are resistance value (51 kOhms vs. 47 kOhms) and tolerance specification (±5% vs. ±10%). All other electrical and mechanical parameters remain equivalent.

Q: Are these parts suitable for new designs?

A: Both parts are classified as obsolete. For new designs, consult current Ohmite product lines for active alternatives with equivalent specifications.
