OY470K Equivalent & Substitute Parts

Part Overview

The OY470K is a 47 Ohm, 2W axial through-hole resistor manufactured by Ohmite with ceramic composition, designed for moisture-resistant and pulse-withstanding applications. This part carries an obsolete product status, making identification of suitable substitutes essential for ongoing design support and procurement continuity. The OY470K is no longer in active production, necessitating the use of equivalent components that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the OY470K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 47 Ohms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial through-hole
• 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
• Number of terminations: 2

The OY470KE meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The OY470KE is the direct substitute for the obsolete OY470K. Both components are manufactured by Ohmite and share identical electrical specifications, ceramic composition, axial package configuration, and physical dimensions. The primary distinction is product status: the OY470K is obsolete while the OY470KE remains in active production with ROHS3 compliance certification, providing improved regulatory alignment and supply chain continuity. Selection of the OY470KE ensures functional equivalence while supporting current manufacturing standards and component availability.

Frequently Asked Questions (FAQ)

Q: Can the OY470KE be used as a direct replacement for the OY470K?

A: Yes. The OY470KE is electrically and mechanically identical to the OY470K across all specified parameters, including resistance, tolerance, power rating, composition, package type, dimensions, and operating temperature range.

Q: What is the primary difference between OY470K and OY470KE?

A: The OY470K is obsolete, while the OY470KE is an active product. The OY470KE also carries ROHS3 compliance certification, whereas the OY470K is RoHS non-compliant.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the OY470K and OY470KE have identical dimensions of 0.276" Dia x 0.748" L (7.00mm x 19.00mm), ensuring compatibility with existing PCB layouts and through-hole mounting configurations.

Q: Does the OY470KE maintain the same thermal and moisture characteristics?

A: Yes. The OY470KE retains the moisture-resistant and pulse-withstanding properties of the OY470K, with identical operating temperature range (-40°C ~ 220°C) and temperature coefficient (-1000 / -1600 ppm/°C).

Q: What packaging options are available for the OY470KE?

A: The OY470KE is supplied in bulk packaging, whereas the OY470K packaging specification was not defined. Both maintain the same axial through-hole component format.
