OX820K Equivalent & Substitute Parts

Part Overview

The OX820K is an 82 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 OX820K is currently classified as obsolete, making identification of suitable alternatives essential for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the OX820K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 82 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 to 220°C
• Temperature coefficient: -1000/-1600 ppm/°C
• Features: Moisture resistant and pulse withstanding

The OX820KE meets all these parameters and serves as a direct manufacturer equivalent. Both parts are from the Ohmite OX series and maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The OX820KE is the direct substitute for the obsolete OX820K. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is product status and regulatory compliance:

The OX820K is obsolete and carries RoHS non-compliant status. The OX820KE is an active product with ROHS3 compliance, making it the appropriate choice for new designs and ongoing production where regulatory compliance is required. Both parts maintain identical electrical performance, thermal characteristics, and physical form factor, ensuring direct interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the OX820KE be used as a direct replacement for the OX820K?

A: Yes. The OX820KE is electrically and mechanically equivalent to the OX820K. Both parts share identical resistance values, tolerance, power rating, physical dimensions, operating temperature range, and ceramic composition with moisture-resistant and pulse-withstanding features.

Q: What is the primary reason to transition from OX820K to OX820KE?

A: The OX820K is obsolete. The OX820KE is an active product from the same manufacturer and series, ensuring continued availability and supply chain reliability. Additionally, the OX820KE meets ROHS3 compliance requirements, whereas the OX820K does not.

Q: Are the physical dimensions identical between OX820K and OX820KE?

A: Yes. Both parts measure 0.217" diameter by 0.650" length (5.50mm x 16.50mm), maintaining identical axial package configuration and board-level compatibility.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the OX820K and OX820KE operate from -40°C to 220°C with identical temperature coefficients of -1000/-1600 ppm/°C.

Q: What packaging options are available?

A: The OX820K is supplied in standard packaging, while the OX820KE is available in bulk packaging. Both maintain the same axial lead configuration and component specifications.
