OY564K Equivalent & Substitute Parts

Part Overview

The OY564K is a 560 kOhms ±10% 2W through-hole resistor with axial leads manufactured by Ohmite. This ceramic composition resistor 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 OY564K is classified as obsolete, making identification of suitable substitutes essential for ongoing component procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY564K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following specifications:

• Resistance Value: 560 kOhms (exact match required)
• Tolerance: ±10% (exact match required)
• Power Rating: 2W (exact match required)
• Composition: Ceramic (exact match required)
• Package Type: Axial (exact match required)
• Physical Dimensions: 0.276" Dia x 0.748" L / 7.00mm x 19.00mm (exact match required)
• Operating Temperature Range: -40°C ~ 220°C (exact match required)
• Temperature Coefficient: -1000 / -1600 ppm/°C (exact match required)
• Features: Moisture Resistant, Pulse Withstanding (exact match required)

The OY564KE meets all substitution criteria as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The OY564KE is the direct equivalent substitute for the obsolete OY564K. Both parts are manufactured by Ohmite and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: the OY564K is obsolete, while the OY564KE is active and ROHS3 compliant. For new designs and ongoing procurement, the OY564KE is the appropriate selection. The OY564KE maintains full compatibility with existing circuit designs specified for the OY564K, with the added benefit of current manufacturing availability and enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the OY564KE be used as a direct replacement for the OY564K?

A: Yes. The OY564KE is electrically and mechanically identical to the OY564K across all specified parameters, including resistance value, tolerance, power rating, package type, and operating temperature range.

Q: What is the primary reason to substitute the OY564K?

A: The OY564K is classified as obsolete. The OY564KE provides continued access to an equivalent part with active manufacturing status.

Q: Are there any differences in physical dimensions between these parts?

A: No. Both the OY564K and OY564KE share identical physical dimensions of 0.276" Dia x 0.748" L (7.00mm x 19.00mm), ensuring direct mechanical compatibility in existing PCB layouts.

Q: What is the difference in RoHS compliance between these parts?

A: The OY564K is RoHS non-compliant, while the OY564KE is ROHS3 compliant. For applications subject to RoHS regulations, the OY564KE is the required selection.

Q: Will the OY564KE function identically to the OY564K in my circuit?

A: Yes. The OY564KE operates within the same electrical specifications, temperature range, and performance characteristics as the OY564K.

Q: Is the OY564KE available in different packaging options?

A: The OY564KE is supplied in bulk packaging, whereas the OY564K packaging specification was not provided. Both parts use the same axial package type.
