AK2365 RF Detector IC Equivalent & Substitute Parts

Part Overview

The AK2365 is a general-purpose RF detector integrated circuit manufactured by Asahi Kasei Microdevices (AKM) in a 32-WFQFN exposed pad surface mount package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The AK2365A serves as the direct active substitute, offering identical electrical and mechanical specifications with enhanced availability and current product status.

Key Parameters

Substitute Part Grouping Explanation

The AK2365A qualifies as a direct substitute based on the following critical parameters:

• Identical package specification: 32-WFQFN exposed pad with 4x4mm footprint
• Matching supply voltage range: 2.6V ~ 5.5V
• Identical supply current requirement: 6 mA
• Identical mounting type: Surface Mount
• Same manufacturer: Asahi Kasei Microdevices (AKM)
• Equivalent RoHS compliance status

The AK2365A is the designated successor part with active product status, making it the primary substitute for obsolete AK2365 applications.

Parameter Comparison

Engineering Selection Recommendations

The AK2365A is the appropriate substitute for the obsolete AK2365 based on:

• Active product status with established supply chain availability
• Full electrical parameter compatibility across all specified operating ranges
• Identical mechanical footprint and package configuration for direct PCB compatibility
• Enhanced RoHS3 compliance certification
• Defined moisture sensitivity level (MSL 1) supporting standard handling and storage procedures

No design modifications are required when transitioning from AK2365 to AK2365A.

Frequently Asked Questions (FAQ)

Q: Can AK2365A be used as a direct replacement for AK2365 without PCB modifications?

A: Yes. The AK2365A maintains identical package dimensions (32-WFQFN 4x4mm), pin configuration, and electrical specifications. No PCB layout changes are necessary.

Q: What is the primary reason for substituting AK2365 with AK2365A?

A: The AK2365 is classified as obsolete. The AK2365A is the active successor part from the same manufacturer with equivalent specifications and superior supply availability.

Q: Are the supply voltage and current requirements identical between both parts?

A: Yes. Both parts operate within 2.6V to 5.5V supply voltage range and require 6 mA supply current.

Q: Does the AK2365A have different RoHS compliance requirements?

A: The AK2365A carries ROHS3 certification, representing current RoHS compliance standards. The original AK2365 is RoHS compliant. Both meet environmental regulatory requirements.

Q: What is the moisture sensitivity level for the AK2365A?

A: The AK2365A is rated MSL 1 (Unlimited), indicating standard moisture handling procedures are applicable without special precautions.

Q: Are there any frequency-specific differences between AK2365 and AK2365A?

A: The AK2365A is specified for 57.6MHz operation. Frequency specifications for the original AK2365 are not provided in the available technical data.
