OY563K Equivalent & Substitute Parts

Part Overview

The OY563K is a 56 kOhms ±10% 2W through-hole axial resistor manufactured by Ohmite with ceramic composition. This component features moisture resistance and pulse withstanding capabilities, designed for applications requiring reliable performance across a wide operating temperature range of -40°C to 220°C. The OY563K carries an obsolete product status, making identification of equivalent substitute parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the OY563K is determined by strict equivalence across electrical and mechanical parameters. The primary substitute, OY563KE, maintains identical specifications for resistance value, tolerance, power rating, ceramic composition, axial package configuration, physical dimensions, operating temperature range, and temperature coefficient. Both parts are manufactured by Ohmite within the OY series and share identical feature sets including moisture resistance and pulse withstanding capability. The substitution is valid based on matching all critical parameters: 56 kOhms resistance, ±10% tolerance, 2W power rating, axial through-hole package, and 7.00mm x 19.00mm dimensions.

Parameter Comparison

Engineering Selection Recommendations

The OY563KE serves as the direct equivalent substitute for the obsolete OY563K. Both components are electrically and mechanically identical across all specified parameters. The primary distinction is product status: the OY563K is obsolete while the OY563KE maintains active production status. Additionally, the OY563KE achieves ROHS3 compliance, whereas the OY563K is RoHS non-compliant. For new designs or ongoing procurement requirements, the OY563KE is the appropriate selection, providing continued availability and regulatory compliance alignment.

Frequently Asked Questions (FAQ)

Q: Can OY563KE directly replace OY563K in existing applications? A: Yes. The OY563KE is electrically and mechanically equivalent to the OY563K across all specified parameters including resistance, tolerance, power rating, package type, and physical dimensions.

Q: What is the primary reason to transition from OY563K to OY563KE? A: The OY563K is obsolete. The OY563KE maintains active production status and ensures long-term component availability for procurement and design support.

Q: Are there compliance differences between these parts? A: Yes. The OY563KE is ROHS3 compliant, while the OY563K is RoHS non-compliant. For applications subject to RoHS regulations, the OY563KE is required.

Q: Do the physical dimensions differ between OY563K and OY563KE? A: No. Both parts share identical dimensions of 0.276" diameter by 0.748" length (7.00mm x 19.00mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: Are the electrical characteristics identical? A: Yes. Both parts maintain 56 kOhms resistance with ±10% tolerance, 2W power rating, identical temperature coefficient of -1000/-1600 ppm/°C, and operating temperature range of -40°C to 220°C.

Q: What packaging options are available? A: The OY563K was supplied in standard packaging, while the OY563KE is available in bulk packaging. Both maintain the same axial through-hole configuration.
