OY220K Equivalent & Substitute Parts

Part Overview

The OY220K is a 22 Ohm, 2W axial through-hole resistor manufactured by Ohmite with ceramic composition, designed for moisture-resistant and pulse-withstanding applications. The part operates across a temperature range of -40°C to 220°C and features a ±10% tolerance specification. This component is currently classified as obsolete, making identification of suitable substitutes essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY220K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for resistance value, tolerance, power rating, ceramic composition, axial package configuration, operating temperature range, and physical dimensions. The OY220KE qualifies as a direct substitute because it matches all these parameters exactly while offering improved product status and compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The OY220KE is the direct equivalent substitute for the OY220K. Both components are manufactured by Ohmite and share identical electrical and mechanical specifications. The primary distinction is product lifecycle status: the OY220K is obsolete while the OY220KE remains in active production. Additionally, the OY220KE achieves ROHS3 compliance, whereas the OY220K is non-compliant. For new designs or ongoing procurement, the OY220KE is the appropriate selection due to its active status and regulatory compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the OY220KE be used as a direct replacement for the OY220K in existing designs?

A: Yes. The OY220KE is electrically and mechanically identical to the OY220K across all specified parameters, including resistance, tolerance, power rating, temperature range, and physical dimensions. The axial package configuration is unchanged.

Q: What is the primary reason to transition from OY220K to OY220KE?

A: The OY220K is classified as obsolete, making long-term procurement difficult. The OY220KE is an active product from the same manufacturer with identical performance characteristics and improved regulatory compliance (ROHS3).

Q: Are there any packaging differences between these parts?

A: The OY220K is supplied in standard packaging, while the OY220KE is supplied in bulk packaging. Both maintain the same axial component form factor and physical dimensions.

Q: Does the OY220KE maintain the same operating temperature range?

A: Yes. Both parts operate across -40°C to 220°C with identical temperature coefficient specifications of -1000/-1600 ppm/°C.

Q: Is the OY220KE suitable for moisture-sensitive applications?

A: Yes. The OY220KE retains the moisture-resistant and pulse-withstanding characteristics of the original OY220K design.
