Parameter Comparison

Engineering Selection Recommendations

The OY474KE is the direct equivalent substitute for the OY474K. Both components share identical electrical specifications, mechanical dimensions, and performance characteristics. The primary distinction is product status: the OY474K is obsolete while the OY474KE remains in active production. Additionally, the OY474KE achieves ROHS3 compliance, whereas the OY474K is RoHS non-compliant. For new designs and ongoing procurement, the OY474KE is the appropriate selection, offering continued availability and regulatory compliance alignment.

Frequently Asked Questions (FAQ)

Q: Can the OY474KE directly replace the OY474K in existing designs?

A: Yes. The OY474KE is electrically and mechanically identical to the OY474K. All electrical parameters, physical dimensions, and performance characteristics are equivalent, enabling direct substitution without circuit modification.

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

A: The OY474K is classified as obsolete, indicating discontinued production and limited availability. The OY474KE is active production, ensuring reliable long-term supply for component procurement and design support.

Q: Does the RoHS compliance difference affect substitution?

A: The OY474KE's ROHS3 compliance provides regulatory alignment for applications subject to RoHS requirements. The OY474K's non-compliance status does not prevent substitution in legacy systems, but the OY474KE is preferred for new designs and applications with regulatory compliance mandates.

Q: Are the physical dimensions identical?

A: Yes. Both the OY474K and OY474KE share identical axial package dimensions of 0.276" diameter by 0.748" length (7.00mm × 19.00mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is determined by equivalence in resistance value (470 kOhms), tolerance (±10%), power rating (2W), composition (ceramic), package type (axial), physical dimensions, operating temperature range (-40°C to 220°C), temperature coefficient (-1000/-1600 ppm/°C), and feature set (moisture resistant, pulse withstanding).
