MAX4444ESE Equivalent & Substitute Parts

Part Overview

The MAX4444ESE is a video amplifier receiver integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as a single-channel receiver amplifier in a 16-SOIC surface mount package. The device is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing design support and procurement requirements. Finding suitable alternatives ensures continuity in system maintenance, repair, and new production builds where legacy compatibility is required.

Substitute Part Grouping Explanation

Substitution of the MAX4444ESE is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Identical -3dB bandwidth of 550 MHz
• Identical slew rate of 5000 V/µs
• Identical supply voltage range of ±4.5V ~ 5.5V
• Identical supply current of 41 mA
• Identical output current per channel of 120 mA
• Single circuit configuration (1 receiver channel)

Mechanical Equivalence Criteria:

• Identical package type: 16-SOIC (0.154", 3.90mm Width)
• Surface mount mounting type
• Same base product number: MAX4444

Compliance Considerations:

• RoHS status and REACH compliance may differ between obsolete and active variants
• Moisture sensitivity level remains constant at MSL 1 (Unlimited)

The MAX4444ESE+ qualifies as a direct substitute based on complete electrical and mechanical parameter alignment with the main part number.

Engineering Selection Recommendations

Primary Recommendation: MAX4444ESE+

The MAX4444ESE+ is the direct functional equivalent of the MAX4444ESE. All electrical parameters, mechanical specifications, and circuit configuration are identical. The substitute part is manufactured by the same supplier (Analog Devices Inc./Maxim Integrated) and maintains full compatibility with existing PCB layouts and circuit designs.

Compliance Advantage:

The MAX4444ESE+ carries active product status and ROHS3 compliance certification, whereas the original MAX4444ESE is obsolete and RoHS non-compliant. For new production builds or systems subject to environmental regulations, the MAX4444ESE+ provides regulatory alignment while maintaining complete technical equivalence.

Packaging Consideration:

The MAX4444ESE+ is supplied in tube packaging format, which differs from the main part specification. This affects handling, storage, and automated assembly processes but does not alter electrical or mechanical compatibility.

Inventory Availability:

The MAX4444ESE+ has significantly higher inventory availability (20,100 pieces) compared to the obsolete main part (2,360 pieces), supporting long-term procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the MAX4444ESE+ be used as a direct replacement for the MAX4444ESE in existing designs?

A: Yes. The MAX4444ESE+ is electrically and mechanically identical to the MAX4444ESE. All electrical parameters, including bandwidth, slew rate, supply voltage, and output current specifications, are equivalent. The 16-SOIC package dimensions and surface mount configuration are identical, allowing direct PCB substitution without design modification.

Q: What is the difference between MAX4444ESE and MAX4444ESE+?

A: The primary differences are product status and compliance certification. The MAX4444ESE is obsolete and RoHS non-compliant, while the MAX4444ESE+ is an active product with ROHS3 compliance. Electrically and mechanically, both parts are identical. The MAX4444ESE+ is supplied in tube packaging rather than an unspecified format.

Q: Are there any compatibility issues with the 16-SOIC package?

A: No. Both the MAX4444ESE and MAX4444ESE+ use the identical 16-SOIC package (0.154", 3.90mm Width). Pin configuration, spacing, and surface mount footprint are equivalent, ensuring direct compatibility with existing PCB designs and assembly processes.

Q: Why is the MAX4444ESE classified as obsolete?

A: The MAX4444ESE has reached end-of-life status with Analog Devices Inc./Maxim Integrated. The MAX4444ESE+ represents the active continuation of this product line with improved compliance characteristics.

Q: Does the tube packaging of MAX4444ESE+ affect circuit performance?

A: No. Packaging format (tube versus other formats) does not affect electrical performance or functional characteristics. The tube format is a handling and storage specification only. The integrated circuit itself and all electrical parameters remain identical.

Q: What is the moisture sensitivity level for both parts?

A: Both the MAX4444ESE and MAX4444ESE+ have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can I use MAX4444ESE+ in applications requiring RoHS compliance?

A: Yes. The MAX4444ESE+ is ROHS3 compliant and suitable for applications with RoHS requirements. The original MAX4444ESE is RoHS non-compliant and should not be used in RoHS-regulated applications.
