Substitute Part Grouping Explanation

Substitution of the MAX4253EUB is determined by strict equivalence across the following critical parameters: dual-circuit configuration, rail-to-rail output capability, surface mount packaging in 10-pin TFSOP/MSOP form factor, supply voltage range compatibility (minimum 2.4 V to 5.5 V maximum), and operating temperature range. Substitute parts must maintain functional compatibility within these electrical and mechanical boundaries.

The substitute parts are grouped into the following categories:

Direct Package Equivalent (Same Manufacturer): MAX4253EUB+ represents the active production variant of the obsolete MAX4253EUB, maintaining identical electrical specifications and packaging.

Cross-Manufacturer Substitutes (Active Status): TLV4113IDGQR (Texas Instruments), LMV823AIST (STMicroelectronics), and TLV2473CDGQR (Texas Instruments) provide functional substitution with rail-to-rail dual-circuit configurations in compatible 10-pin surface mount packages. These parts meet or exceed the supply voltage range and operating temperature requirements of the original device.

Discontinued Substitute: TLV2633IDGSR (Texas Instruments) is listed as discontinued at DiGi Electronics and is included for reference only; this part is not recommended for new designs.
