AX47GK Equivalent & Substitute Parts

Part Overview

The AX47GK is a 4.7 Ohm, 3.5W through-hole radial 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 AX47GK is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and component procurement.

Substitute Part Grouping Explanation

Substitution of the AX47GK is determined by strict equivalence across electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 4.7 Ohms
• Tolerance: ±10%
• Power rating: 3.5W
• Composition: Ceramic
• Package configuration: Radial lead
• Operating temperature range: -55°C to 150°C
• Physical dimensions: 0.591" L x 0.827" W with maximum seated height of 1.102"
• Feature set: Flame retardant coating, moisture resistance, non-inductive design, pulse withstanding capability

The AX47GKE meets all specified parameters and is classified as an equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The AX47GKE is the direct equivalent substitute for the obsolete AX47GK. Both parts are manufactured by Ohmite within the PulsEater® A series and share identical electrical specifications and physical dimensions. The primary distinction is product status and regulatory compliance: the AX47GK is obsolete, while the AX47GKE is active and ROHS3 compliant. For new designs and ongoing procurement, the AX47GKE is the appropriate selection. For legacy system maintenance requiring exact historical equivalence, the AX47GKE provides functional and mechanical compatibility with improved regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the AX47GKE be used as a direct replacement for the AX47GK in existing designs?

A: Yes. The AX47GKE is electrically and mechanically equivalent to the AX47GK. Both parts have identical resistance values, tolerance, power ratings, physical dimensions, and operating temperature ranges. The AX47GKE is suitable for direct substitution in PCB layouts and circuit designs originally specified for the AX47GK.

Q: What is the difference between the AX47GK and AX47GKE?

A: The AX47GK is classified as obsolete, while the AX47GKE is an active product. The AX47GKE is ROHS3 compliant, whereas the AX47GK is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Are there any packaging differences between these parts?

A: The AX47GK and AX47GKE share identical radial lead packaging, physical dimensions of 0.591" L x 0.827" W, and maximum seated height of 1.102". Both are supplied with two terminations. The primary packaging difference is that the AX47GKE is supplied in bulk packaging, while the AX47GK packaging specification is listed as standard.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching resistance value (4.7 Ohms), tolerance (±10%), power rating (3.5W), ceramic composition, radial lead package configuration, operating temperature range (-55°C to 150°C), physical dimensions, and feature set including flame retardant coating, moisture resistance, non-inductive design, and pulse withstanding capability.

Q: Is the AX47GKE suitable for applications requiring RoHS compliance?

A: Yes. The AX47GKE is ROHS3 compliant, making it suitable for applications with RoHS regulatory requirements. The obsolete AX47GK is RoHS non-compliant.
