OY561K Equivalent & Substitute Parts

Part Overview

The OY561K is a 560 Ohms ±10% 2W through-hole axial resistor manufactured by Ohmite with ceramic composition, moisture-resistant and pulse-withstanding characteristics. This part is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement continuity. The OY561K 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 OY561K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part OY561KE maintains identical specifications for resistance value, tolerance, power rating, ceramic composition, axial package configuration, physical dimensions, operating temperature range, and temperature coefficient. Both parts feature moisture-resistant and pulse-withstanding characteristics with two terminations. The primary distinction is product status: OY561K is obsolete while OY561KE is active, and packaging differs between the main part and substitute (unspecified versus bulk). Substitution is valid when all electrical parameters and physical form factor remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

The OY561KE serves as a direct electrical and mechanical equivalent to the OY561K. Both parts are manufactured by Ohmite and share identical resistance, tolerance, power rating, composition, package configuration, and operating specifications. Selection between these parts should be based on product availability and compliance requirements. The OY561K is obsolete and should be replaced with OY561KE for new designs and ongoing procurement. The OY561KE offers the additional advantage of ROHS3 compliance, whereas the OY561K is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can OY561KE be used as a direct replacement for OY561K? A: Yes. The OY561KE is electrically and mechanically equivalent to the OY561K. All critical parameters including resistance, tolerance, power rating, ceramic composition, axial package type, physical dimensions, and operating temperature range are identical.

Q: What is the primary reason to substitute OY561K with OY561KE? A: The OY561K is classified as obsolete. The OY561KE is an active product from the same manufacturer with identical electrical and mechanical specifications, ensuring design continuity and procurement availability.

Q: Are there any compliance differences between OY561K and OY561KE? A: Yes. The OY561KE is ROHS3 compliant, while the OY561K is RoHS non-compliant. Both parts are REACH Unaffected and classified as EAR99 for export purposes.

Q: Do the physical dimensions remain the same between OY561K and OY561KE? A: Yes. Both parts have identical axial package dimensions of 0.276" diameter × 0.748" length (7.00mm × 19.00mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What is the operating temperature range for both parts? A: Both OY561K and OY561KE operate across -40°C to 220°C with a temperature coefficient of -1000/-1600 ppm/°C.
