AX470K Equivalent & Substitute Parts Reference

Part Overview

The AX470K is a 47 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 AX470K is currently classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX470K is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 47 Ohms
• Tolerance: ±10%
• Power rating: 4.6W
• Composition: Ceramic
• Package configuration: Radial through-hole
• Operating temperature range: -55°C ~ 150°C
• Physical dimensions: 0.591" L x 0.827" W (15.00mm x 21.00mm)
• Height seated maximum: 1.102" (28.00mm)
• Termination count: 2

The AX470KE meets all these criteria and is identified as a parametric equivalent within the PulsEater® A series.

Parameter Comparison

Engineering Selection Recommendations

The AX470KE is the direct substitute for the obsolete AX470K. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is product status and regulatory compliance: the AX470K is obsolete, while the AX470KE is active and ROHS3 compliant. For new designs or ongoing production requiring this 47 Ohm, 4.6W radial ceramic resistor, the AX470KE is the appropriate selection. The AX470KE maintains full compatibility with existing PCB layouts and circuit designs originally specified for the AX470K.

Frequently Asked Questions (FAQ)

Q: Can the AX470KE be used as a direct replacement for the AX470K?

A: Yes. The AX470KE is electrically and mechanically equivalent to the AX470K across all specified parameters, including resistance, tolerance, power rating, composition, package type, operating temperature range, and physical dimensions.

Q: What is the primary reason to transition from AX470K to AX470KE?

A: The AX470K is obsolete. The AX470KE is an active product from the same manufacturer and series, ensuring continued availability and supply chain support.

Q: Are there any compliance differences between these parts?

A: Yes. The AX470KE is ROHS3 compliant, while the AX470K is RoHS non-compliant. Both parts maintain REACH Unaffected status. For applications subject to RoHS regulations, the AX470KE is the required selection.

Q: Will the AX470KE fit the same PCB footprint as the AX470K?

A: Yes. Both parts share identical physical dimensions (0.591" L x 0.827" W, 15.00mm x 21.00mm) and maximum seated height (1.102" or 28.00mm), ensuring direct PCB compatibility.

Q: Are the electrical characteristics identical?

A: Yes. Both parts are 47 Ohm ±10% resistors with 4.6W power rating, ceramic composition, and identical operating temperature range (-55°C ~ 150°C). All functional features, including flame retardant coating, moisture resistance, non-inductive design, and pulse withstanding capability, are identical.
