OD151JE Equivalent & Substitute Parts

Part Overview

The OD151JE is a 150 Ohm ±5% 1/4W through-hole axial resistor manufactured by Ohmite as part of the Little Demon® OD series. This carbon composition resistor features pulse withstanding capability and is designed for axial lead applications. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where this specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OD151JE is determined by the following critical parameters:

• Resistance Value: 150 Ohms (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Package Type: Axial configuration (exact match required)
• Composition: Carbon Composition (exact match required)
• Physical Dimensions: 0.098" Dia x 0.276" L (exact match required)
• Tolerance: ±5% or wider tolerance acceptable (±10% is acceptable as a substitute)

The OD151KE qualifies as a substitute because it maintains identical resistance value, power rating, package type, composition, and physical dimensions. The tolerance difference (±10% versus ±5%) represents a relaxation of the specification, which is acceptable in substitution scenarios where the circuit design permits wider tolerance margins.

Parameter Comparison

Engineering Selection Recommendations

Both the OD151JE and OD151KE are obsolete products within the Little Demon® OD series. Selection between these parts should be based on circuit tolerance requirements:

• OD151JE (±5% tolerance): Select when circuit design specifications require tighter tolerance control and the ±5% specification is a functional requirement.
• OD151KE (±10% tolerance): Select when circuit design permits wider tolerance margins. The ±10% tolerance specification is acceptable for applications where component value variation within this range does not impact circuit performance.

Both parts maintain identical electrical performance characteristics in terms of resistance value and power rating, identical physical dimensions for PCB layout compatibility, and equivalent compliance certifications (ROHS3 Compliant, MSL 1).

Frequently Asked Questions (FAQ)

Q: Can OD151KE replace OD151JE in all applications?

A: OD151KE can replace OD151JE when the circuit design tolerates ±10% component tolerance. If the original design specifically requires ±5% tolerance, substitution with OD151KE may not be appropriate without circuit re-evaluation.

Q: Are the physical dimensions identical between OD151JE and OD151KE?

A: Yes. Both parts share identical dimensions of 0.098" Dia x 0.276" L (2.50mm x 7.00mm), ensuring direct mechanical compatibility in axial lead PCB layouts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both OD151JE and OD151KE are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), meeting equivalent environmental and regulatory requirements.

Q: Why are both parts classified as obsolete?

A: Both the OD151JE and OD151KE are obsolete products. For new designs or long-term production requirements, evaluation of current-generation resistor alternatives from active product lines is recommended.

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

A: The primary difference is tolerance specification. OD151JE carries ±5% tolerance while OD151KE carries ±10% tolerance. All other electrical and mechanical parameters remain identical.
