OF152JE Equivalent & Substitute Parts

Part Overview

The OF152JE is a 1.5 kOhms ±5% 0.5W through-hole resistor manufactured by Ohmite as part of the Little Demon® OF series. This axial carbon composition resistor features pulse withstanding capability and is designed for through-hole PCB applications. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OF152JE is determined by the following critical parameters:

• Resistance Value: Must be 1.5 kOhms
• Power Rating: Must be 0.5W (1/2W) minimum
• 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 construction
• Termination Count: Must have 2 terminations
• Compliance: ROHS3 Compliant

The OF152KE qualifies as a manufacturer-recommended substitute. While it carries a wider tolerance specification (±10% versus ±5%), it maintains identical resistance value, power rating, package type, physical dimensions, composition, and compliance certifications. The tolerance difference reflects a relaxed specification that remains functionally compatible for applications where the original ±5% tolerance is not a critical design constraint.

Parameter Comparison

Engineering Selection Recommendations

Both the OF152JE and OF152KE are obsolete products from Ohmite's Little Demon® OF series. Selection between these parts should be based on application tolerance requirements:

• OF152JE (±5% tolerance): Select when circuit design specifies ±5% tolerance or tighter resistance accuracy.
• OF152KE (±10% tolerance): Select when application tolerance permits ±10% variance or when OF152JE availability is constrained.

Both parts maintain identical physical dimensions, power ratings, package configuration, and compliance certifications (ROHS3). The substitution is mechanically and electrically compatible for PCB mounting and circuit functionality, with the tolerance specification as the primary differentiator.

Frequently Asked Questions (FAQ)

Q: Can OF152KE replace OF152JE in any application?

A: OF152KE is mechanically and electrically compatible with OF152JE for applications where ±10% tolerance is acceptable. If the circuit design requires ±5% tolerance, OF152KE may not meet specifications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both OF152JE and OF152KE measure 0.150" Dia x 0.406" L (3.80mm x 10.30mm) and use identical axial package configuration, ensuring direct PCB mounting compatibility.

Q: Do both parts meet RoHS compliance?

A: Yes. Both OF152JE and OF152KE are ROHS3 Compliant with MSL Rating 1 (Unlimited), meeting current environmental and regulatory requirements.

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

A: The tolerance specification differs: OF152JE carries ±5% tolerance while OF152KE carries ±10% tolerance. All other electrical and mechanical parameters are identical.

Q: Are these parts still in production?

A: No. Both OF152JE and OF152KE are classified as obsolete products. Availability is limited to existing inventory stocks.
