OY56GK Equivalent & Substitute Parts

Part Overview

The OY56GK is a 5.6 Ohms ±10% 2W through-hole axial resistor manufactured by Ohmite with ceramic composition, moisture-resistant and pulse-withstanding characteristics. This component is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement planning. The OY56GK operates across a temperature range of -40°C to 220°C and is suitable for applications requiring ceramic resistor construction with axial lead configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY56GK is determined by strict equivalence across the following critical parameters:

• Resistance value: 5.6 Ohms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial with 2 terminations
• Physical dimensions: 0.276" Dia x 0.748" L (7.00mm x 19.00mm)
• Operating temperature range: -40°C ~ 220°C
• Temperature coefficient: -1000 / -1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OY56GKE meets all these criteria and is identified as a direct substitute for the obsolete OY56GK.

Parameter Comparison

Engineering Selection Recommendations

The OY56GKE is the direct equivalent substitute for the obsolete OY56GK. Both components share identical electrical and mechanical specifications, including resistance value, tolerance, power rating, ceramic composition, axial package configuration, and operating temperature range.

The primary distinction between the two parts is product status and regulatory compliance. The OY56GK is obsolete and RoHS non-compliant, while the OY56GKE is an active product with ROHS3 compliance. For new designs or ongoing procurement, the OY56GKE is the appropriate selection. For legacy system maintenance where the original OY56GK specification must be retained, the OY56GKE provides full functional and physical compatibility while offering improved regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the OY56GKE be used as a direct replacement for the OY56GK in existing designs?

A: Yes. The OY56GKE is electrically and mechanically identical to the OY56GK. Both components have the same resistance value (5.6 Ohms), tolerance (±10%), power rating (2W), physical dimensions (0.276" Dia x 0.748" L), and operating temperature range (-40°C ~ 220°C). The axial lead configuration and ceramic composition are identical, ensuring pin-for-pin and footprint compatibility.

Q: What is the difference between OY56GK and OY56GKE?

A: The OY56GK is classified as obsolete, while the OY56GKE is an active product. Additionally, the OY56GK is RoHS non-compliant, whereas the OY56GKE meets ROHS3 compliance standards. All electrical and mechanical parameters are equivalent.

Q: Are there any packaging differences between these parts?

A: The OY56GK packaging specification is not defined in the available data. The OY56GKE is supplied in bulk packaging. Both components use the same axial lead package type with identical physical dimensions.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in resistance value (5.6 Ohms), tolerance (±10%), power rating (2W), ceramic composition, axial package configuration, physical dimensions (0.276" Dia x 0.748" L), operating temperature range (-40°C ~ 220°C), and temperature coefficient (-1000 / -1600 ppm/°C).

Q: Is the OY56GKE suitable for applications requiring RoHS compliance?

A: Yes. The OY56GKE is ROHS3 compliant, making it suitable for applications with RoHS compliance requirements. The obsolete OY56GK is RoHS non-compliant.
