OX150K Equivalent & Substitute Parts

Part Overview

The OX150K is a 15 Ohms ±10% 1W through-hole resistor in axial configuration manufactured by Ohmite. This ceramic composition resistor features moisture resistance and pulse withstanding capabilities, designed for operating temperatures from -40°C to 220°C. The OX150K is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution of the OX150K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match:

• Resistance value: 15 Ohms
• Tolerance: ±10%
• Power rating: 1W
• Composition: Ceramic
• Package configuration: Axial
• Physical dimensions: 0.217" Dia x 0.650" L (5.50mm x 16.50mm)
• Operating temperature range: -40°C ~ 220°C
• Temperature coefficient: -1000 / -1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OX150KE meets all these criteria and is classified as a direct equivalent within the Ohmite OX series.

Parameter Comparison

Engineering Selection Recommendations

The OX150KE is the direct equivalent substitute for the obsolete OX150K. Both components are manufactured by Ohmite within the same OX series and share identical electrical specifications and physical dimensions. The primary distinction is product status: the OX150K is obsolete while the OX150KE remains in active production.

The OX150KE offers an additional compliance advantage: it is ROHS3 compliant, whereas the OX150K is RoHS non-compliant. For applications requiring RoHS compliance, the OX150KE is the appropriate selection. For legacy systems or applications without RoHS requirements, both parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the OX150KE be used as a direct replacement for the OX150K?

A: Yes. The OX150KE is electrically and mechanically identical to the OX150K. Both components have the same resistance value (15 Ohms), tolerance (±10%), power rating (1W), physical dimensions (0.217" Dia x 0.650" L), and operating temperature range (-40°C ~ 220°C). The axial package configuration and lead terminations are identical.

Q: What is the primary reason to substitute the OX150K?

A: The OX150K is classified as obsolete. The OX150KE is the active production equivalent, ensuring continued availability and supply chain reliability.

Q: Are there any compliance differences between these parts?

A: Yes. The OX150KE is ROHS3 compliant, while the OX150K is RoHS non-compliant. For applications subject to RoHS regulations, the OX150KE is required.

Q: Will the OX150KE fit in the same PCB footprint as the OX150K?

A: Yes. Both components have identical physical dimensions and axial package configuration. No PCB layout modifications are required.

Q: Are the electrical characteristics identical?

A: Yes. Both parts share identical resistance (15 Ohms), tolerance (±10%), power rating (1W), temperature coefficient (-1000 / -1600 ppm/°C), and operating temperature range (-40°C ~ 220°C).
