OX470K Equivalent & Substitute Parts

Part Overview

The OX470K is a 47 Ohm, 1W axial through-hole resistor manufactured by Ohmite with ceramic composition, designed for moisture-resistant and pulse-withstanding applications. This part is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and procurement continuity. The OX470K series provides reliable performance across industrial temperature ranges from -40°C to 220°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OX470K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute must maintain identical resistance value (47 Ohms), tolerance (±10%), power rating (1W), ceramic composition, axial package configuration, and operating temperature range (-40°C ~ 220°C). The temperature coefficient range (-1000 / -1600 ppm/°C) and functional features (moisture resistance and pulse withstanding capability) are preserved in qualified substitutes. Physical dimensions (0.217" Dia x 0.650" L) ensure mechanical compatibility in existing PCB layouts and through-hole mounting applications.

Parameter Comparison

Engineering Selection Recommendations

The OX470KE serves as the direct substitute for the obsolete OX470K. Both parts are manufactured by Ohmite and maintain identical electrical specifications and physical dimensions. The primary distinction is product status: the OX470K is obsolete while the OX470KE is active in production. Additionally, the OX470KE achieves ROHS3 compliance, whereas the OX470K is RoHS non-compliant. For new designs and ongoing procurement, the OX470KE is the appropriate selection, providing equivalent performance with current regulatory compliance and assured supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can OX470KE replace OX470K in existing applications? A: Yes. The OX470KE is electrically and mechanically equivalent to the OX470K across all specified parameters, including resistance, tolerance, power rating, temperature range, and physical dimensions. Direct substitution is valid for through-hole PCB mounting applications.

Q: What is the difference between OX470K and OX470KE? A: The OX470K is obsolete; the OX470KE is an active production part from the same manufacturer. The OX470KE additionally meets ROHS3 compliance standards. All electrical and mechanical characteristics remain identical.

Q: Are the physical dimensions identical? A: Yes. Both parts share the same axial package dimensions of 0.217" Dia x 0.650" L (5.50mm x 16.50mm), ensuring compatibility with existing PCB layouts and mounting holes.

Q: Does the RoHS compliance difference affect electrical performance? A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical functional characteristics across the specified operating temperature range.

Q: What packaging options are available? A: The OX470K was supplied in standard packaging; the OX470KE is available in bulk packaging, suitable for high-volume production environments.
