OX471K Equivalent & Substitute Parts

Part Overview

The OX471K is a 470 Ohms ±10% 1W 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 OX471K is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OX471K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute component must match the following specifications:

• Resistance value: 470 Ohms
• Tolerance: ±10%
• Power rating: 1W
• Composition: Ceramic
• Package configuration: Axial with 2 terminations
• Physical dimensions: 0.217" Dia x 0.650" L (5.50mm x 16.50mm)
• Operating temperature range: -40°C ~ 220°C
• Temperature coefficient: -1000 / -1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OX471KE meets all these criteria and is identified as a direct substitute for the obsolete OX471K.

Parameter Comparison

Engineering Selection Recommendations

The OX471KE is the direct equivalent substitute for the obsolete OX471K. Both components are manufactured by Ohmite and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: the OX471K is obsolete, while the OX471KE is active and ROHS3 compliant. For new designs or ongoing production requiring this 470 Ohm 1W axial ceramic resistor, the OX471KE provides continued availability with improved regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the OX471KE be used as a direct replacement for the OX471K in existing designs?

A: Yes. The OX471KE is electrically and mechanically identical to the OX471K across all specified parameters, including resistance value, tolerance, power rating, package dimensions, and operating temperature range. No circuit modifications are required.

Q: What is the primary reason for substituting the OX471K?

A: The OX471K is classified as obsolete. The OX471KE, an active product from the same manufacturer, provides continued component availability for procurement and production.

Q: Are there any compliance differences between the OX471K and OX471KE?

A: Yes. The OX471K is RoHS non-compliant, while the OX471KE is ROHS3 compliant. For applications subject to RoHS regulations, the OX471KE is the appropriate selection.

Q: Do the physical dimensions of the OX471KE match the OX471K?

A: Yes. Both components have identical axial package dimensions of 0.217" Dia x 0.650" L (5.50mm x 16.50mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What is the operating temperature range for both components?

A: Both the OX471K and OX471KE operate across the same temperature range of -40°C to 220°C, with a temperature coefficient of -1000 / -1600 ppm/°C.
