OY47GK Equivalent & Substitute Parts

Part Overview

The OY47GK is a 4.7 Ohms ±10% 2W through-hole resistor with axial leads manufactured by Ohmite. This ceramic composition resistor features moisture-resistant and pulse-withstanding characteristics, designed for applications requiring reliable performance across a wide operating temperature range of -40°C to 220°C. The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY47GK is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 4.7 Ohms
• 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 OY47GKE meets all these requirements and is identified as a direct substitute for the obsolete OY47GK.

Parameter Comparison

Engineering Selection Recommendations

The OY47GKE is the direct equivalent substitute for the obsolete OY47GK. Both parts are manufactured by Ohmite within the OY series and maintain identical electrical specifications and physical dimensions. The primary distinction is product status: the OY47GK is obsolete while the OY47GKE remains in active production.

The OY47GKE offers improved regulatory compliance, meeting ROHS3 standards compared to the non-compliant status of the original part. This substitution is suitable for new designs, production continuations, and field replacements where component availability and regulatory compliance are considerations.

Frequently Asked Questions (FAQ)

Q: Can the OY47GKE be used as a direct replacement for the OY47GK in existing designs?

A: Yes. The OY47GKE is electrically and mechanically identical to the OY47GK. All critical parameters including resistance, tolerance, power rating, package type, and operating temperature range are equivalent. The parts are pin-compatible and dimensionally identical.

Q: What is the primary reason to substitute the OY47GK with the OY47GKE?

A: The OY47GK is classified as obsolete, making the OY47GKE the active production equivalent. The OY47GKE also provides improved regulatory compliance with ROHS3 certification.

Q: Are there any differences in performance between these parts?

A: No performance differences exist. Both parts share identical electrical characteristics, temperature coefficients, and operating ranges. The OY47GKE is manufactured to the same specifications as the original OY47GK.

Q: What packaging options are available for the OY47GKE?

A: The OY47GKE is supplied in bulk packaging, whereas the original OY47GK packaging specification was not provided. Confirm packaging requirements with your procurement department.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both the OY47GK and OY47GKE are rated for operating temperatures from -40°C to 220°C and feature pulse-withstanding and moisture-resistant characteristics suitable for demanding thermal environments.
