MAX4737EBE-T Equivalent & Substitute Parts

Part Overview

The MAX4737EBE-T is a 4-circuit IC switch with SPST-NO (Single Pole Single Throw - Normally Open) configuration, manufactured by Analog Devices Inc./Maxim Integrated. This component operates as a 1:1 multiplexer/demultiplexer with 4.5Ohm on-state resistance and is housed in a 16-UCSP (2x2) surface mount package.

The MAX4737EBE-T is classified as Obsolete. Identifying equivalent substitute parts is necessary for design continuity, procurement flexibility, and long-term product support when the original part reaches end-of-life status or inventory constraints occur.

Engineering Selection Recommendations

The MAX4737EBE+T is a direct functional equivalent to the MAX4737EBE-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status: the MAX4737EBE-T is Obsolete, while the MAX4737EBE+T is Active. The MAX4737EBE+T is the recommended selection for new designs and ongoing procurement due to its active product status and confirmed availability. Both parts maintain ROHS3 compliance and EAR99 export classification.

The packaging format difference (Cut Tape & Digi-Reel for MAX4737EBE+T versus standard packaging for MAX4737EBE-T) does not affect electrical or mechanical compatibility and relates only to supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Can MAX4737EBE+T be used as a direct replacement for MAX4737EBE-T in existing designs?

A: Yes. The MAX4737EBE+T is electrically and mechanically identical to the MAX4737EBE-T. All electrical parameters, operating ranges, and package specifications are equivalent. No circuit modifications are required.

Q: What is the difference between MAX4737EBE-T and MAX4737EBE+T?

A: The parts are functionally identical. The primary difference is product lifecycle status: MAX4737EBE-T is Obsolete, while MAX4737EBE+T is Active. The suffix notation (+T versus -T) reflects packaging format designation from the manufacturer. Both use the same 16-UCSP (2x2) package.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is based on matching: switch circuit type (SPST-NO, 4 circuits), on-state resistance (4.5Ohm), channel matching (100mOhm), supply voltage range (1.8V-5.5V), switch timing (80ns/40ns), bandwidth (300MHz), charge injection (5pC), channel capacitance (9pF), leakage current (500pA), crosstalk (-110dB @ 1MHz), and operating temperature range (-40°C to 85°C).
