OF153JE Equivalent & Substitute Parts

Part Overview

The OF153JE is a 15 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 part is classified as obsolete, making identification of suitable equivalent components necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OF153JE is determined by the following critical parameters:

• Resistance Value: Must be 15 kOhms
• Power Rating: Must be 0.5W (1/2W) minimum
• Package Configuration: Must be axial through-hole
• Physical Dimensions: Must match 0.150" Dia x 0.406" L (3.80mm x 10.30mm)
• Composition: Carbon composition construction
• Compliance: ROHS3 compliance required

The OF153KE qualifies as a direct substitute based on these parameters. While the tolerance specification differs (±10% versus ±5%), the resistance value, power rating, package type, physical dimensions, composition, and compliance certifications remain identical. The tolerance variance represents a relaxation of the specification rather than a functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The OF153KE is suitable as a substitute for the OF153JE in applications where the tolerance specification can accommodate ±10% variance. Both components maintain identical electrical performance characteristics in terms of resistance value and power dissipation capability. Both parts are ROHS3 compliant and carry MSL rating 1, indicating no moisture sensitivity constraints during storage or handling.

Selection between these parts should be based on circuit tolerance requirements. Applications requiring ±5% tolerance precision must use the OF153JE or equivalent ±5% tolerance components. Applications with tolerance budgets accommodating ±10% variance may utilize the OF153KE.

Frequently Asked Questions (FAQ)

Q: Can OF153KE replace OF153JE in all applications?

A: The OF153KE is electrically and mechanically compatible with the OF153JE. Substitution is valid when circuit design tolerances permit ±10% resistance variance. Applications with strict ±5% tolerance requirements must use components meeting that specification.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both OF153JE and OF153KE share identical axial package dimensions of 0.150" Dia x 0.406" L (3.80mm x 10.30mm), ensuring mechanical compatibility in PCB layouts and through-hole mounting configurations.

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

A: The tolerance specification differs. OF153JE provides ±5% tolerance, while OF153KE provides ±10% tolerance. All other electrical and mechanical parameters, including resistance value, power rating, composition, and compliance certifications, are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both OF153JE and OF153KE are ROHS3 compliant and carry MSL rating 1 (unlimited moisture sensitivity), meeting current environmental and regulatory requirements.

Q: Why is the OF153JE classified as obsolete?

A: The OF153JE is listed as obsolete by the manufacturer. The OF153KE remains available as a functionally equivalent alternative from the same manufacturer and series.
