MAX703ESA-T Equivalent & Substitute Parts

Part Overview

The MAX703ESA-T is a single-channel supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for battery backup circuit applications. This component operates as a push-pull, totem pole output supervisor with active-low reset functionality. The MAX703ESA-T is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. Substitute parts maintain identical electrical and mechanical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX703ESA-T are qualified based on strict electrical and mechanical parameter matching. All substitute parts maintain identical specifications across the following critical parameters: single-channel voltage monitoring at 4.65V threshold, push-pull totem pole output configuration, active-low reset with 140ms minimum timeout, 8-SOIC package form factor (0.154", 3.90mm width), operating temperature range of -40°C to 85°C, surface mount mounting type, ROHS3 compliance, MSL 1 rating, and REACH unaffected status.

Substitutes are categorized into three groups: direct manufacturer equivalents (same base product number with different packaging), parametric equivalents (different base product numbers with identical electrical and mechanical specifications), and manufacturer-recommended alternatives (cross-manufacturer parts meeting all specified parameters).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the MAX703ESA-T. Selection among substitutes should prioritize active product status and compliance certifications. The MAX703ESA+T offers the most direct substitution path as an active variant of the same base product number from the original manufacturer. The MAX690AESA+T and MAX802LESA+T provide parametric equivalence with active product status and full ROHS3 compliance.

For cross-manufacturer applications, the STM703M6F from STMicroelectronics meets all specified electrical and mechanical parameters while maintaining active product status and equivalent compliance certifications. The ADM690AARNZ-REEL and ADM802LARNZ-REEL from Analog Devices Inc. provide additional parametric equivalence options with active status and superior inventory availability.

All substitute parts are ROHS3 compliant, REACH unaffected, and maintain MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can MAX703ESA+T directly replace MAX703ESA-T in existing designs?

A: Yes. The MAX703ESA+T is electrically and mechanically identical to the MAX703ESA-T. The primary difference is packaging format (Tape & Reel versus Tube) and active product status. Pin configuration, electrical specifications, and performance characteristics are identical.

Q: What is the difference between MAX690AESA+T and MAX802LESA+T substitutes?

A: Both parts maintain identical electrical specifications and package form factors as the MAX703ESA-T. The difference lies in base product numbers (MAX690 versus MAX802), indicating different product lines within the Analog Devices supervisor IC portfolio. All three parts (MAX703, MAX690, MAX802) meet the specified 4.65V threshold, push-pull totem pole output, and 140ms reset timeout requirements.

Q: Is STM703M6F from STMicroelectronics a suitable cross-manufacturer substitute?

A: Yes. The STM703M6F meets all critical electrical and mechanical parameters: 4.65V voltage threshold, push-pull totem pole output, active-low reset with 140ms minimum timeout, 8-SOIC package, -40°C to 85°C operating range, ROHS3 compliance, and MSL 1 rating. Cross-manufacturer substitution is valid when all specified parameters match.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel, Cut Tape, or Tube) affects only supply chain logistics and handling procedures. Electrical performance and specifications remain identical across all packaging variants of the same part number.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What inventory considerations should guide part selection?

A: Inventory availability varies across substitutes. MAX703ESA+T offers 8,819 units, ADM690AARNZ-REEL provides 10,300 units, and MAX802LESA+T has 4,100 units in stock. Selection based on availability should not compromise electrical or mechanical compatibility requirements.
