MX584TH Equivalent & Substitute Parts

Part Overview

The MX584TH is a series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated, designed for precision power management applications. This programmable reference offers selectable output voltages (2.5V, 5V, 7.5V, 10V) with ±0.3% tolerance and operates across a wide input voltage range of 4.5V to 30V. The device is currently classified as obsolete, making equivalent substitute parts necessary for ongoing system support and new design implementations. Active alternatives from Analog Devices provide enhanced performance specifications and improved compliance standards while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX584TH is determined by strict adherence to the following electrical and mechanical parameters:

Critical Compatibility Parameters:

• Output voltage selection: 2.5V, 5V, 7.5V, 10V (programmable)
• Output current: 10 mA
• Input voltage range: 4.5V ~ 30V
• Package type: TO-99-8 Metal Can (Through Hole)
• Operating temperature range: -55°C ~ 125°C or compatible subset
• Reference type: Series voltage reference

Performance Parameters (Tolerance Hierarchy):

• Tolerance: ±0.3% (baseline) to ±0.1% (enhanced)
• Temperature coefficient: 15 ppm/°C to 30 ppm/°C
• Noise specification: 50 µVp-p (0.1Hz to 10Hz)

All substitute parts listed maintain identical output voltage options, output current, input voltage range, and package configuration. Substitutes are grouped by tolerance grade and operating temperature range, with active product status and RoHS3 compliance providing advantages over the obsolete MX584TH.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Full Temperature Range, Enhanced Performance): AD584TH is the primary substitute for MX584TH. It maintains the full operating temperature range (-55°C ~ 125°C), improves tolerance to ±0.14%, and is actively manufactured with ROHS3 compliance. This part provides superior performance while preserving all functional compatibility.

Military-Grade Alternatives: AD584TH/883B and AD584SH/883B are qualified to MIL-STD-883 and maintain full temperature range operation. These parts are suitable for applications requiring military-grade components or enhanced reliability certifications. AD584TH/883B offers ±0.14% tolerance; AD584SH/883B maintains ±0.3% tolerance matching the original MX584TH specification.

Commercial-Grade Options (Restricted Temperature Range): AD584JH and AD584KH operate within 0°C ~ 70°C temperature range. AD584KH provides the tightest tolerance (±0.1%) and lowest temperature coefficient (15 ppm/°C) among commercial-grade parts. These substitutes are suitable only for applications not requiring the full -55°C ~ 125°C operating range.

Compliance Consideration: All active Analog Devices substitutes are ROHS3 compliant, addressing the non-compliance status of the obsolete MX584TH. This compliance improvement is mandatory for new designs and recommended for legacy system updates.

Frequently Asked Questions (FAQ)

Q: Can AD584JH or AD584KH replace MX584TH in all applications? A: Only if your application operates within the 0°C ~ 70°C temperature range. These parts are not suitable for systems requiring the full -55°C ~ 125°C operating range of the MX584TH. For full temperature range compatibility, use AD584TH, AD584SH, or military-grade variants.

Q: What is the difference between AD584TH and AD584SH? A: Both maintain -55°C ~ 125°C operation and ±0.3% tolerance. AD584TH offers ±0.14% tolerance with 20 ppm/°C temperature coefficient, while AD584SH provides ±0.3% tolerance with 30 ppm/°C temperature coefficient. Select AD584TH for improved accuracy; select AD584SH for cost optimization when ±0.3% tolerance is acceptable.

Q: Are military-grade parts (883B qualified) necessary for my application? A: Military qualification (MIL-STD-883) is required only for defense, aerospace, or applications with explicit military-grade component specifications. For commercial applications, standard AD584 variants provide equivalent functionality at lower cost.

Q: Does the package remain the same across all substitutes? A: Yes. All substitute parts use TO-99-8 Metal Can through-hole packaging, maintaining identical PCB layout and mechanical compatibility with the MX584TH.

Q: Why is RoHS3 compliance important for the MX584TH replacement? A: The original MX584TH is RoHS non-compliant. All active Analog Devices substitutes are ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and system updates. Non-compliance may restrict component availability and create regulatory exposure in certain markets.

Q: Can I use JM38510/12801BGA as a substitute? A: JM38510/12801BGA maintains the same output voltage options, output current, input range, and temperature range as MX584TH. However, tolerance specification is not provided for this part. Verify tolerance requirements with the manufacturer before selection if ±0.3% tolerance is critical to your application.
