OX563K Equivalent & Substitute Parts

Part Overview

The OX563K is a 56 kOhms ±10% 1W through-hole resistor in axial package 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 OX563K is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OX563K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match:

• Resistance value: 56 kOhms
• Tolerance: ±10%
• Power rating: 1W
• Composition: Ceramic
• Package configuration: Axial
• Physical dimensions: 0.217" Dia × 0.650" L
• Temperature coefficient: -1000/-1600 ppm/°C
• Operating temperature range: -40°C to 220°C
• Features: Moisture Resistant, Pulse Withstanding

The OX563KE meets all these criteria and is manufactured by the same supplier (Ohmite), ensuring direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The OX563KE is the direct equivalent for the obsolete OX563K. Both parts are manufactured by Ohmite and share identical electrical specifications and physical dimensions. The primary distinction is product status: the OX563K is obsolete while the OX563KE is active and currently in production.

The OX563KE offers improved compliance status, meeting RoHS requirements where the OX563K does not. For new designs or ongoing production requiring compliance with modern regulatory standards, the OX563KE is the appropriate selection. The active product status of OX563KE ensures continued availability and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can OX563KE be used as a direct replacement for OX563K?

A: Yes. The OX563KE is electrically and mechanically identical to the OX563K. Both parts have the same resistance value (56 kOhms), tolerance (±10%), power rating (1W), package type (axial), physical dimensions, and operating characteristics. The OX563KE is the active production equivalent.

Q: What is the difference between OX563K and OX563KE?

A: The OX563K is obsolete, while OX563KE is active. The OX563KE is RoHS compliant, whereas the OX563K is not. All electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: The OX563K was supplied in standard packaging, while OX563KE is supplied in bulk packaging. Both maintain identical axial package configuration and physical dimensions (0.217" Dia × 0.650" L).

Q: Is the OX563KE suitable for high-temperature applications?

A: Yes. The OX563KE operates across the full temperature range of -40°C to 220°C, matching the OX563K specification. Temperature coefficient is -1000/-1600 ppm/°C.

Q: What compliance certifications apply to OX563KE?

A: The OX563KE is RoHS compliant with Moisture Sensitivity Level 1 (Unlimited). ECCN classification is EAR99.
