OY680K Equivalent & Substitute Parts

Part Overview

The OY680K is a 68 Ohms ±10% 2W through-hole axial resistor manufactured by Ohmite with ceramic composition. This component 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 OY680K is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY680K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute component must match the following specifications without deviation:

• Resistance value: 68 Ohms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial through-hole
• Operating temperature range: -40°C to 220°C
• Physical dimensions: 0.276" Dia × 0.748" L (7.00mm × 19.00mm)
• Termination count: 2
• Features: Moisture resistant and pulse withstanding capability

The OY680KE meets all these criteria and is classified as a direct equivalent substitute for the obsolete OY680K.

Parameter Comparison

Engineering Selection Recommendations

The OY680KE is the direct equivalent substitute for the obsolete OY680K. Both components are manufactured by Ohmite and share identical electrical specifications and physical dimensions. The primary distinction is product status: the OY680K is obsolete while the OY680KE remains in active production.

For new designs or ongoing procurement, the OY680KE is the appropriate selection. This substitute provides continuity of electrical performance while offering the advantage of active product status and ROHS3 compliance, addressing regulatory requirements that the original OY680K does not meet.

Frequently Asked Questions (FAQ)

Q: Can the OY680KE be used as a direct replacement for the OY680K in existing designs?

A: Yes. The OY680KE is electrically and mechanically identical to the OY680K. All critical parameters—resistance, tolerance, power rating, operating temperature range, physical dimensions, and features—are equivalent. Direct substitution is appropriate for both repair and redesign applications.

Q: What is the significance of the product status difference between OY680K and OY680KE?

A: The OY680K is classified as obsolete, indicating it is no longer manufactured or supported by Ohmite. The OY680KE is active production, ensuring ongoing availability and supply chain reliability. For new procurement, the OY680KE is the recommended choice.

Q: Are there compliance differences between these two parts?

A: Yes. The OY680K is RoHS non-compliant, while the OY680KE is ROHS3 compliant. If your application or market requires RoHS compliance, the OY680KE satisfies this requirement.

Q: Will the OY680KE fit the same PCB footprint as the OY680K?

A: Yes. Both components have identical axial package dimensions of 0.276" Dia × 0.748" L (7.00mm × 19.00mm) with two terminations. No PCB layout modifications are required.

Q: Are the electrical characteristics identical between OY680K and OY680KE?

A: Yes. Both components have 68 Ohms resistance with ±10% tolerance, 2W power rating, ceramic composition, -1000/-1600 ppm/°C temperature coefficient, and -40°C to 220°C operating temperature range. Moisture resistance and pulse withstanding features are identical.
