Substitute Part Grouping Explanation

Substitution of the OY392K is determined by strict equivalence across the following critical parameters:

• Resistance value: 3.9 kOhms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial with 2 terminations
• Physical dimensions: 0.276" Dia × 0.748" L (7.00mm × 19.00mm)
• Operating temperature range: -40°C to 220°C
• Temperature coefficient: -1000/-1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OY392KE meets all specified electrical and mechanical parameters, providing direct functional equivalence to the obsolete OY392K.

Parameter Comparison

Engineering Selection Recommendations

The OY392KE is the direct equivalent substitute for the obsolete OY392K. Both components share identical electrical specifications, mechanical dimensions, and performance characteristics across all critical parameters. The primary distinction is product status: the OY392K is obsolete while the OY392KE maintains active production status.

The OY392KE offers improved regulatory compliance, meeting ROHS3 requirements compared to the non-compliant OY392K. This compliance advantage makes the OY392KE the preferred selection for new designs and ongoing component replenishment where regulatory standards apply.

Both components are manufactured by Ohmite within the OY series and are suitable for applications requiring 3.9 kOhms resistance at 2W power dissipation across the -40°C to 220°C operating range.

Frequently Asked Questions (FAQ)

Q: Can the OY392KE directly replace the OY392K in existing designs?

A: Yes. The OY392KE provides complete electrical and mechanical equivalence to the OY392K. All critical parameters including resistance, tolerance, power rating, package type, and physical dimensions are identical. Direct substitution is supported without circuit modification.

Q: What is the significance of the product status difference?

A: The OY392K is classified as obsolete, indicating discontinued manufacturing. The OY392KE maintains active production status, ensuring reliable long-term availability for component procurement and design support.

Q: Are there compliance differences between these parts?

A: Yes. The OY392KE is ROHS3 compliant, while the OY392K is RoHS non-compliant. For applications subject to RoHS regulations, the OY392KE is the required selection.

Q: Do the axial package dimensions differ between these parts?

A: No. Both components share identical physical dimensions of 0.276" diameter by 0.748" length (7.00mm × 19.00mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What packaging formats are available?

A: The OY392K is supplied in standard packaging, while the OY392KE is available in bulk packaging. Both formats contain the same component specifications.

Q: Are the temperature performance characteristics identical?

A: Yes. Both the OY392K and OY392KE operate across -40°C to 220°C with identical temperature coefficients of -1000/-1600 ppm/°C, providing equivalent thermal performance.
