OY560K Equivalent & Substitute Parts

Part Overview

The OY560K is a 56 Ohm, 2W axial through-hole resistor manufactured by Ohmite with ceramic composition, designed for moisture-resistant and pulse-withstanding applications. The part is currently obsolete, making identification of compatible substitutes essential for ongoing maintenance, repair, and legacy system support. Equivalent parts must maintain identical electrical specifications and physical dimensions to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution for the OY560K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part OY560KE qualifies as a direct equivalent based on the following criteria:

• Identical resistance value: 56 Ohms
• Matching tolerance: ±10%
• Equal power rating: 2W
• Same composition: Ceramic
• Identical package configuration: Axial
• Matching physical dimensions: 0.276" Dia × 0.748" L
• Equivalent operating temperature range: -40°C to 220°C
• Identical temperature coefficient: -1000/-1600 ppm/°C
• Matching features: Moisture Resistant, Pulse Withstanding
• Same number of terminations: 2

The OY560KE maintains full electrical and mechanical compatibility with the OY560K, differing only in product status (Active vs. Obsolete) and packaging format (Bulk vs. standard).

Parameter Comparison

Engineering Selection Recommendations

The OY560KE is the direct equivalent substitute for the obsolete OY560K. Both parts are manufactured by Ohmite and share identical electrical and mechanical specifications. The primary distinction is product status: the OY560K is obsolete while the OY560KE remains in active production.

For new designs or ongoing procurement, the OY560KE is the appropriate selection. The OY560KE offers the additional advantage of ROHS3 compliance, whereas the OY560K is RoHS non-compliant. Both parts maintain equivalent performance across all specified operating parameters and are suitable for direct substitution in existing circuits without modification.

Frequently Asked Questions (FAQ)

Q: Can the OY560KE directly replace the OY560K in existing circuits?

A: Yes. The OY560KE is electrically and mechanically identical to the OY560K. All critical parameters—resistance value, tolerance, power rating, physical dimensions, operating temperature range, and temperature coefficient—are equivalent. Direct substitution is possible without circuit redesign.

Q: What is the difference between OY560K and OY560KE?

A: The OY560K is obsolete, while the OY560KE is in active production. The OY560KE also carries ROHS3 compliance, whereas the OY560K is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical between OY560K and OY560KE?

A: Yes. Both parts have identical axial package dimensions of 0.276" diameter × 0.748" length (7.00mm × 19.00mm). They are mechanically interchangeable in PCB layouts and through-hole applications.

Q: What packaging formats are available for the OY560KE?

A: The OY560KE is supplied in Bulk packaging. The OY560K was supplied in standard packaging. Both formats contain the same component specifications.

Q: Are there any compliance differences between the two parts?

A: Yes. The OY560KE is ROHS3 compliant, while the OY560K is RoHS non-compliant. Both parts are REACH Unaffected and classified under ECCN EAR99. For applications requiring RoHS compliance, the OY560KE is the appropriate selection.

Q: What is the operating temperature range for these resistors?

A: Both the OY560K and OY560KE operate across -40°C to 220°C with a temperature coefficient of -1000/-1600 ppm/°C.
