OX560K Equivalent & Substitute Parts

Part Overview

The OX560K is a 56 Ohms ±10% 1W through-hole resistor with axial leads, manufactured by Ohmite. This ceramic composition resistor features moisture-resistant and pulse-withstanding characteristics, designed for applications requiring reliable performance across a wide operating temperature range of -40°C to 220°C. The OX560K is currently classified as obsolete, making identification of suitable substitute components essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete OX560K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute component must match the following specifications without deviation:

• Resistance value: 56 Ohms
• Tolerance: ±10%
• Power rating: 1W
• Composition: Ceramic
• Package configuration: Axial with 2 terminations
• 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 OX560KE meets all these criteria and serves as a direct functional equivalent for the obsolete OX560K.

Parameter Comparison

Engineering Selection Recommendations

The OX560KE is the direct substitute for the obsolete OX560K. Both components are manufactured by Ohmite and share identical electrical and mechanical specifications. The primary distinction is product status: the OX560K is obsolete while the OX560KE remains in active production with improved RoHS3 compliance. For new designs and ongoing production requiring the OX560K specification, the OX560KE provides full functional equivalence with the added benefit of current availability and enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the OX560KE be used as a direct replacement for the OX560K in existing designs?

A: Yes. The OX560KE is electrically and mechanically identical to the OX560K across all specified parameters, including resistance value, tolerance, power rating, package dimensions, and operating temperature range. Direct substitution is appropriate for all applications.

Q: What is the difference between the OX560K and OX560KE?

A: The OX560K is obsolete, while the OX560KE is an active product. The OX560KE also carries ROHS3 compliance, whereas the OX560K is RoHS non-compliant. All electrical and mechanical characteristics remain identical.

Q: Are there any packaging differences between these parts?

A: Both components use identical axial package configuration with 0.217" diameter and 0.650" length (5.50mm x 16.50mm). The OX560K was supplied with standard packaging, while the OX560KE is available in bulk packaging.

Q: What certifications apply to the OX560KE?

A: The OX560KE is ROHS3 compliant and REACH unaffected. Both the OX560K and OX560KE carry the same ECCN (EAR99) and HTSUS (8533.21.0090) classifications.

Q: Is the temperature coefficient identical between both parts?

A: Yes. Both the OX560K and OX560KE specify a temperature coefficient of -1000 / -1600 ppm/°C with an operating temperature range of -40°C to 220°C.
