MAX608ESA Equivalent & Substitute Parts

Part Overview

The MAX608ESA is a boost regulator positive output step-up DC-DC controller IC manufactured by Analog Devices Inc./Maxim Integrated. This component functions as a transistor driver for step-up (boost) topology power management applications, delivering a single positive output phase. The MAX608ESA is classified as obsolete, which necessitates identification of equivalent substitute components for new designs or ongoing production requirements. Active alternatives with identical electrical and mechanical specifications are available to ensure design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX608ESA is determined by strict equivalence across the following critical parameters:

• Topology & Function: Boost regulator controller with positive output, single-phase configuration
• Electrical Specifications: Supply voltage range 1.8V ~ 16.5V, switching frequency up to 300kHz, transistor driver output type
• Package Compatibility: 8-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm width)
• Operating Conditions: Temperature range -40°C ~ 85°C, MSL rating 1
• Manufacturer Continuity: Analog Devices Inc./Maxim Integrated product line

The MAX608ESA+ meets all substitution criteria as a direct equivalent with identical electrical and mechanical parameters. The primary distinction is product status: MAX608ESA is obsolete, while MAX608ESA+ is active production.

Parameter Comparison

Engineering Selection Recommendations

The MAX608ESA+ is the direct substitute for the obsolete MAX608ESA. Both components share identical electrical performance specifications and physical packaging, ensuring pin-for-pin compatibility and functional equivalence in boost regulator controller applications.

The MAX608ESA+ offers the additional advantage of active product status, ensuring ongoing availability and manufacturing support. The MAX608ESA+ also achieves ROHS3 compliance, whereas the original MAX608ESA is RoHS non-compliant. For new designs or production transitions, the MAX608ESA+ is the appropriate selection.

Both parts maintain REACH Unaffected status and EAR99 export classification. The MSL rating of 1 (Unlimited) applies to both variants, indicating no moisture sensitivity constraints for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can MAX608ESA+ be used as a direct replacement for MAX608ESA in existing designs?
