Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY820K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute component must match the following specifications without deviation:

• Resistance value: 82 Ohms
• 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 OY820KE meets all these criteria and is classified as an active product, providing continuity for applications currently using the obsolete OY820K.

Parameter Comparison

Engineering Selection Recommendations

The OY820KE is the direct substitute for the obsolete OY820K. Both components are manufactured by Ohmite within the OY series and maintain identical electrical and mechanical specifications. The primary distinction is product status: the OY820K is obsolete while the OY820KE is active and available in production quantities.

The OY820KE provides improved regulatory compliance, meeting ROHS3 requirements compared to the non-compliant status of the OY820K. For new designs or ongoing production requiring this 82 Ohm 2W ceramic axial resistor, the OY820KE is the appropriate selection. Both components share identical performance characteristics across resistance, tolerance, power rating, temperature range, and physical form factor, ensuring direct functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the OY820KE be used as a direct replacement for the OY820K?

A: Yes. The OY820KE is electrically and mechanically identical to the OY820K. Both components have 82 Ohms resistance, ±10% tolerance, 2W power rating, ceramic composition, and identical axial package dimensions. The OY820KE is the active production equivalent.

Q: What is the difference between OY820K and OY820KE?

A: The OY820K is obsolete; the OY820KE is active. The OY820KE also meets ROHS3 compliance standards, whereas the OY820K is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Are there any packaging differences between these parts?

A: No. Both components use identical axial packaging with dimensions of 0.276" Dia x 0.748" L (7.00mm x 19.00mm). They are mechanically interchangeable in PCB layouts and through-hole applications.

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

A: Both the OY820K and OY820KE operate across -40°C to 220°C, with a temperature coefficient of -1000/-1600 ppm/°C.

Q: Is the OY820KE suitable for moisture-sensitive applications?

A: Yes. The OY820KE features moisture resistance and pulse withstanding capabilities, making it suitable for applications requiring environmental protection and transient pulse handling.
