OY224K Equivalent & Substitute Parts

Part Overview

The OY224K is a 220 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 OY224K 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 OY224K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 220 kOhms
• 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 to 220°C
• Temperature coefficient: -1000/-1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OY224KE meets all these parameters and is classified as an active product, providing continuity for applications currently using the obsolete OY224K.

Parameter Comparison

Engineering Selection Recommendations

The OY224KE is the direct substitute for the obsolete OY224K. Both components are manufactured by Ohmite and maintain identical electrical specifications and physical dimensions. The primary distinction is product status: the OY224K is obsolete while the OY224KE is active and currently in production.

For new designs or component replenishment, the OY224KE is the appropriate selection. The OY224KE offers the additional advantage of ROHS3 compliance, whereas the OY224K is RoHS non-compliant. Both components maintain REACH Unaffected status and carry the same ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the OY224KE directly replace the OY224K in existing applications?

A: Yes. The OY224KE is electrically and mechanically identical to the OY224K. All critical parameters—resistance, tolerance, power rating, temperature range, and physical dimensions—are equivalent. Direct substitution is appropriate for both repair and redesign scenarios.

Q: What is the difference between OY224K and OY224KE?

A: The OY224K is classified as obsolete, while the OY224KE is an active product. The OY224KE also carries ROHS3 compliance, whereas the OY224K is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: The OY224K is supplied in standard packaging, while the OY224KE is supplied in bulk packaging. Both maintain the same axial lead configuration and physical dimensions of 0.276" Dia x 0.748" L (7.00mm x 19.00mm).

Q: Will the OY224KE work in circuits designed for the OY224K?

A: Yes. The OY224KE meets all electrical and mechanical requirements of the OY224K. Pin-to-pin compatibility and functional performance are maintained.

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

A: Both the OY224K and OY224KE operate across -40°C to 220°C with a temperature coefficient of -1000/-1600 ppm/°C.
