AX100K Equivalent & Substitute Parts

Part Overview

The AX100K is a 10 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 AX100K is currently classified as obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AX100K is based on electrical and mechanical parameter equivalence within the PulsEater® A series. The substitute part AX100KE maintains identical specifications across all critical parameters: 10 Ohm resistance value, ±10% tolerance, 4.6W power rating, ceramic composition, radial package configuration, operating temperature range of -55°C to 150°C, and physical dimensions of 0.591" L x 0.827" W with maximum seated height of 1.102". The key differentiator is product status and compliance certification, with AX100KE classified as active and RoHS3 compliant, whereas AX100K is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The AX100KE is the direct substitute for the obsolete AX100K. Both components are manufactured by Ohmite within the same PulsEater® A series and share identical electrical and mechanical specifications. The primary distinction is product lifecycle status: AX100K is obsolete while AX100KE is actively manufactured and supported. Additionally, AX100KE carries RoHS3 compliance certification, whereas AX100K is RoHS non-compliant. For new designs and ongoing production requiring regulatory compliance, AX100KE is the appropriate selection. Both components are equivalent for applications requiring 10 Ohm, 4.6W ceramic radial resistors with flame retardant and moisture-resistant properties across the -55°C to 150°C operating range.

Frequently Asked Questions (FAQ)

Q: Can AX100KE be used as a direct replacement for AX100K in existing assemblies?

A: Yes. The AX100KE is electrically and mechanically equivalent to AX100K. Both components have identical resistance (10 Ohms), tolerance (±10%), power rating (4.6W), package configuration (radial), physical dimensions, and operating temperature range (-55°C to 150°C). PCB layout and circuit design require no modification.

Q: What is the difference between AX100K and AX100KE?

A: The primary differences are product status and compliance. AX100K is obsolete and RoHS non-compliant. AX100KE is actively manufactured, RoHS3 compliant, and carries REACH Unaffected status. All electrical and mechanical parameters are identical.

Q: Are there packaging differences between AX100K and AX100KE?

A: AX100K is supplied in standard packaging, while AX100KE is supplied in bulk packaging. Both maintain identical component specifications and radial package configuration suitable for through-hole PCB assembly.

Q: Is RoHS3 compliance a functional requirement for substitution?

A: RoHS3 compliance is a regulatory and supply chain consideration rather than a functional electrical parameter. If your application or market requires RoHS compliance, AX100KE is the appropriate selection. If RoHS compliance is not required, both components are functionally equivalent.

Q: Can AX100KE be used in high-temperature applications?

A: Yes. AX100KE operates across the full temperature range of -55°C to 150°C, identical to AX100K. Both components are suitable for applications within this operating temperature specification.
