OA822KE Equivalent & Substitute Parts

Part Overview

The OA822KE is an 8.2 kOhms ±10% 1W through-hole resistor manufactured by Ohmite in the Little Demon® OA series. This carbon composition axial resistor features pulse withstanding capability and is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute components is essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OA822KE is determined by matching the following critical electrical and mechanical parameters:

• Resistance Value: 8.2 kOhms (exact match required)
• Tolerance: ±10% (defines acceptable resistance range)
• Power Rating: 1W (thermal dissipation capability)
• Package Configuration: Axial through-hole (mechanical fit and PCB compatibility)
• Composition Type: Carbon composition or ceramic (functional equivalence for general-purpose applications)

The OX822KE meets all substitution criteria as an active-status alternative with identical electrical specifications and compatible axial packaging.

Parameter Comparison

Engineering Selection Recommendations

The OX822KE is the direct substitute for the OA822KE based on matching electrical and mechanical specifications. Key selection factors include:

Product Status: The OX822KE holds active product status with 4484 units in stock, compared to the obsolete OA822KE with 991 units available. Active status ensures long-term availability and supply chain continuity.

Compliance: The OX822KE is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both parts maintain REACH unaffected status and EAR99 export classification.

Composition Difference: The OX822KE uses ceramic composition instead of carbon composition. Both compositions support the specified 1W power rating and ±10% tolerance. The ceramic variant includes moisture-resistant properties as an additional feature.

Environmental Specifications: The OX822KE provides defined operating temperature range (-40°C ~ 220°C) and temperature coefficient specifications (-1000 / -1600 ppm/°C), offering enhanced environmental performance documentation compared to the main part.

Frequently Asked Questions (FAQ)

Q: Can the OX822KE directly replace the OA822KE in existing designs?

A: Yes. Both parts share identical resistance value (8.2 kOhms), tolerance (±10%), power rating (1W), and axial package configuration. The electrical and mechanical compatibility is complete.

Q: What is the difference between carbon composition and ceramic composition resistors?

A: Both compositions meet the specified electrical parameters for this application. Ceramic composition offers moisture-resistant properties and defined temperature coefficients. Carbon composition is the original technology used in the OA822KE series.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist. The OA822KE measures 0.236" Dia x 0.591" L (6.00mm x 15.00mm). The OX822KE measures 0.217" Dia x 0.650" L (5.50mm x 16.50mm). Both are axial through-hole packages suitable for standard PCB layouts.

Q: Does the OX822KE meet current regulatory standards?

A: Yes. The OX822KE is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the OA822KE classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The OX822KE represents the active alternative within the Ohmite resistor portfolio for this resistance value and power rating.

Q: What is the inventory situation for these parts?

A: The OA822KE has 991 units in stock. The OX822KE has 4484 units in stock, providing significantly greater availability for new orders and production requirements.
