AX220K Equivalent & Substitute Parts

Part Overview

The AX220K is a 22 Ohm, 4.6W radial through-hole resistor manufactured by Ohmite as part of the PulsEater® A series. This ceramic composition resistor features flame retardant coating, moisture resistance, non-inductive design, and pulse withstanding capability. The AX220K is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where this component specification is required.

Substitute Part Grouping Explanation

Substitution eligibility for the AX220K is determined by strict equivalence across the following critical parameters:

• Resistance value: 22 Ohms
• Tolerance: ±10%
• Power rating: 4.6W
• Composition: Ceramic
• Package configuration: Radial
• Operating temperature range: -55°C ~ 150°C
• Physical dimensions: 0.591" L x 0.827" W (15.00mm x 21.00mm)
• Height - Seated (Max): 1.102" (28.00mm)
• Number of terminations: 2
• Feature set: Flame Retardant Coating, Moisture Resistant, Non-Inductive, Pulse Withstanding, Safety

The AX220KE meets all substitution criteria as a direct equivalent within the PulsEater® A series.

Parameter Comparison

Engineering Selection Recommendations

The AX220KE is the direct functional equivalent of the AX220K. Both components share identical electrical specifications, physical dimensions, and feature sets within the PulsEater® A series. The primary distinction is product status and regulatory compliance: the AX220K is obsolete, while the AX220KE maintains active production status and achieves ROHS3 compliance, compared to the non-compliant status of the original part.

For new designs or system replacements where the AX220K specification is required, the AX220KE provides full electrical and mechanical compatibility with the added benefit of current regulatory compliance and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the AX220KE be used as a direct replacement for the AX220K in existing assemblies?

A: Yes. The AX220KE is electrically and mechanically identical to the AX220K. Both components have the same resistance value (22 Ohms), tolerance (±10%), power rating (4.6W), physical dimensions, and operating temperature range. The radial package configuration and lead spacing are identical, allowing direct substitution in PCB layouts and through-hole applications.

Q: What is the difference between the AX220K and AX220KE?

A: The components are functionally equivalent. The AX220K is classified as obsolete, while the AX220KE is in active production. The AX220KE achieves ROHS3 compliance, whereas the AX220K is RoHS non-compliant. Both maintain REACH Unaffected status.

Q: Are there any packaging differences between these parts?

A: The AX220K and AX220KE share identical physical specifications: 0.591" L x 0.827" W (15.00mm x 21.00mm) with a maximum seated height of 1.102" (28.00mm). The primary packaging difference is that the AX220K may be supplied in tape or reel format, while the AX220KE is supplied in bulk packaging. This does not affect component performance or compatibility.

Q: What certifications and compliance standards apply to these resistors?

A: Both the AX220K and AX220KE carry REACH Unaffected status and are classified under ECCN EAR99. The AX220KE additionally meets ROHS3 compliance requirements. Both components are rated for HTSUS code 8533.21.0090.

Q: Can these resistors handle pulse applications?

A: Yes. Both the AX220K and AX220KE are specifically designed with pulse withstanding capability as part of the PulsEater® A series feature set. This characteristic is maintained across both components.
