AW560K Equivalent & Substitute Parts

Part Overview

The AW560K is a 56 Ohm, 2.5W 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 AW560K is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AW560K is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 56 Ohms
• Tolerance: ±10%
• Power rating: 2.5W
• Composition: Ceramic
• Package configuration: Radial
• Operating temperature range: -55°C ~ 150°C
• Physical dimensions: 0.787" L x 0.512" W (20.00mm x 13.00mm)
• Height - Seated (Max): 0.866" (22.00mm)
• Number of terminations: 2
• Feature set: Flame Retardant Coating, Moisture Resistant, Non-Inductive, Pulse Withstanding, Safety

The AW560KE meets all specified parameters and is manufactured by Ohmite within the same PulsEater® A series, ensuring direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AW560KE is the direct equivalent for the obsolete AW560K. Both parts are manufactured by Ohmite within the PulsEater® A series and share identical electrical specifications, tolerance, power rating, and physical dimensions. The primary distinction is product status and regulatory compliance: the AW560KE is active production and ROHS3 compliant, whereas the AW560K is obsolete and RoHS non-compliant.

For new designs and ongoing production requiring compliance with current environmental regulations, the AW560KE is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, the AW560K remains functionally equivalent where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the AW560KE be used as a direct replacement for the AW560K in existing designs?

A: Yes. The AW560KE is electrically and mechanically identical to the AW560K. Both parts have 56 Ohm resistance, ±10% tolerance, 2.5W power rating, ceramic composition, radial package configuration, and identical physical dimensions. Direct substitution is supported without circuit modification.

Q: What is the difference between the AW560K and AW560KE?

A: The primary differences are product status and regulatory compliance. The AW560K is obsolete, while the AW560KE is in active production. The AW560KE is ROHS3 compliant; the AW560K is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: The AW560K is supplied in standard packaging, while the AW560KE is supplied in bulk packaging. Both maintain identical component specifications and radial lead configuration.

Q: Which part should be selected for new production?

A: The AW560KE should be selected for new production due to active product status and ROHS3 compliance. The AW560K is obsolete and should not be specified for new designs.

Q: Do these parts have the same operating temperature range?

A: Yes. Both the AW560K and AW560KE operate across the identical temperature range of -55°C to 150°C.
