MX574AJN Equivalent & Substitute Parts

Part Overview

The MX574AJN is a 12-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for single-ended input data acquisition applications. It features a Successive Approximation Register (SAR) architecture with a 40 kHz sampling rate and operates with external or internal voltage references. The device is packaged in a 28-pin DIP configuration for through-hole mounting.

The MX574AJN is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for legacy systems.

Engineering Selection Recommendations

MX574AJN+ (Direct Manufacturer Equivalent)

The MX574AJN+ is the direct equivalent to the MX574AJN, maintaining identical electrical and mechanical specifications. This part is currently in active production status and is ROHS3 compliant, addressing regulatory requirements for new designs and production runs. The MX574AJN+ is supplied in tube packaging and represents the primary replacement option for obsolete MX574AJN units.

MX574AKN+ (Parametric Equivalent)

The MX574AKN+ is a parametric equivalent offering identical electrical and mechanical performance to the MX574AJN. This part is also in active production and ROHS3 compliant. With higher inventory availability (2200 pcs), the MX574AKN+ may be selected based on supply chain considerations and lead time requirements.

Both substitute parts are suitable for direct replacement in applications currently using the MX574AJN, provided that the through-hole 28-DIP package footprint and electrical specifications remain compatible with the existing circuit design.

Frequently Asked Questions (FAQ)

Q: Can MX574AJN+ and MX574AKN+ be used interchangeably with MX574AJN?

A: Yes. Both substitute parts maintain identical electrical parameters (12-bit resolution, 40 kHz sampling rate, single-ended input, SAR architecture, parallel data interface, ±11.4V ~ 16.5V analog supply, 5V digital supply, 0°C ~ 70°C operating range) and mechanical specifications (28-DIP package, through-hole mounting). They are functionally equivalent for direct replacement.

Q: What is the difference between MX574AJN+, MX574AJN, and MX574AKN+?

A: The MX574AJN is obsolete. The MX574AJN+ is the direct manufacturer equivalent in active production with ROHS3 compliance. The MX574AKN+ is a parametric equivalent also in active production with ROHS3 compliance. All three parts share identical electrical and mechanical specifications.

Q: Are there packaging differences between these parts?

A: The MX574AJN packaging type is not specified in available documentation. Both MX574AJN+ and MX574AKN+ are supplied in tube packaging. The physical package type (28-DIP, 0.600", 15.24mm) and mounting method (through-hole) are identical across all three parts.

Q: Which substitute part should I select for new production?

A: Both MX574AJN+ and MX574AKN+ are suitable for new production. Selection may be based on inventory availability, lead time, and supplier preference. Both parts are ROHS3 compliant and in active production status.

Q: Are these parts RoHS compliant?

A: The MX574AJN is RoHS non-compliant. Both substitute parts, MX574AJN+ and MX574AKN+, are ROHS3 compliant, meeting current regulatory requirements for electronic components.
