Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY272K is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.7 kOhms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial
• Operating temperature range: -40°C ~ 220°C
• Temperature coefficient: -1000 / -1600 ppm/°C
• Physical dimensions: 0.276" Dia x 0.748" L (7.00mm x 19.00mm)
• Termination count: 2

The OY272KE qualifies as a direct substitute, maintaining identical electrical and mechanical specifications while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The OY272KE is the direct equivalent substitute for the obsolete OY272K. Both parts maintain identical electrical specifications, mechanical dimensions, and functional characteristics. The primary distinction lies in product status and regulatory compliance: the OY272KE is an active product with ROHS3 compliance, whereas the OY272K is obsolete and RoHS non-compliant. For new designs or component replenishment, the OY272KE is the appropriate selection. The OY272KE is available in bulk packaging with significantly higher inventory levels (10,397 pcs) compared to the OY272K (930 pcs).

Frequently Asked Questions (FAQ)

Q: Can the OY272KE be used as a direct replacement for the OY272K?

A: Yes. The OY272KE is electrically and mechanically identical to the OY272K across all specified parameters, including resistance value, tolerance, power rating, temperature range, and physical dimensions.

Q: What is the difference between OY272K and OY272KE?

A: The OY272KE is the active production variant of the OY272K series. Both parts share identical electrical and mechanical specifications. The OY272KE offers ROHS3 compliance and is currently in active production, whereas the OY272K is obsolete and RoHS non-compliant.

Q: Are there any packaging differences between these parts?
