OX120K Equivalent & Substitute Parts

Part Overview

The OX120K is a 12 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 OX120K is currently classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OX120K is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 12 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 to 220°C
• Temperature coefficient: -1000/-1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OX120KE meets all these criteria and is identified as a direct substitute for the OX120K.

Parameter Comparison

Engineering Selection Recommendations

The OX120KE is the direct equivalent substitute for the OX120K. Both parts are manufactured by Ohmite and share identical electrical specifications, tolerance, power rating, composition, and physical dimensions. The primary distinction is product status: the OX120K is obsolete while the OX120KE is active and currently in production.

The OX120KE offers an additional compliance advantage: it is ROHS3 compliant, whereas the OX120K is RoHS non-compliant. For applications requiring RoHS compliance, the OX120KE 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 OX120KE be used as a direct replacement for the OX120K?

A: Yes. The OX120KE is electrically and mechanically equivalent to the OX120K. Both parts have identical resistance values, tolerance, power ratings, physical dimensions, and operating temperature ranges. The OX120KE is the active production equivalent of the obsolete OX120K.

Q: What is the difference between the OX120K and OX120KE?

A: The OX120K is obsolete, while the OX120KE is an active product. The OX120KE is ROHS3 compliant, whereas the OX120K is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: The OX120K packaging designation is listed as "-" (unspecified), while the OX120KE is supplied in bulk packaging. Both parts use the same axial configuration and physical dimensions.

Q: Is the OX120KE suitable for high-temperature applications?

A: Yes. The OX120KE operates across the same temperature range as the OX120K: -40°C to 220°C, with a temperature coefficient of -1000/-1600 ppm/°C.

Q: What is the moisture resistance rating of the OX120KE?

A: The OX120KE is moisture resistant. The Moisture Sensitivity Level (MSL) is not applicable for this component type.
