Substitute Part Grouping Explanation

Substitution eligibility for the OY472K is determined by strict equivalence across the following critical parameters:

• Resistance value: 4.7 kOhms
• 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 ~ 220°C
• Temperature coefficient: -1000 / -1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OY472KE meets all substitution criteria as a direct equivalent from the same manufacturer, with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The OY472KE is the direct substitute for the obsolete OY472K. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in circuit applications. The primary distinction is product status: the OY472K is obsolete while the OY472KE is active and currently in production.

The OY472KE offers improved compliance status, meeting ROHS3 requirements compared to the non-compliant OY472K. This compliance improvement supports modern procurement standards and regulatory requirements without altering component performance or circuit behavior.

Selection of the OY472KE is appropriate for new designs, redesigns, and component replacement in existing applications where the OY472K is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the OY472KE be used as a direct replacement for the OY472K?

A: Yes. The OY472KE is electrically and mechanically identical to the OY472K. Both components have the same resistance value (4.7 kOhms), tolerance (±10%), power rating (2W), physical dimensions (0.276" Dia x 0.748" L), operating temperature range (-40°C ~ 220°C), and features (moisture resistant, pulse withstanding).

Q: What is the primary reason to substitute the OY472K?

A: The OY472K is classified as obsolete. The OY472KE provides continued availability from the same manufacturer with identical specifications.

Q: Are there any compliance differences between these parts?

A: Yes. The OY472KE is ROHS3 compliant, while the OY472K is RoHS non-compliant. This compliance improvement does not affect electrical or mechanical performance.

Q: Will the OY472KE fit in the same PCB footprint as the OY472K?

A: Yes. Both components have identical axial package dimensions of 0.276" Dia x 0.748" L (7.00mm x 19.00mm) and 2 terminations, ensuring identical PCB layout compatibility.

Q: Are the temperature coefficients identical?

A: Yes. Both the OY472K and OY472KE have the same temperature coefficient range of -1000 / -1600 ppm/°C, ensuring equivalent thermal performance across the operating temperature range of -40°C to 220°C.
