Engineering Selection Recommendations

For new designs and active production environments, MAX690ACPA+ and MAX694CPA+ are the preferred substitute selections, as both maintain active product status with Analog Devices Inc./Maxim Integrated. Both parts carry identical electrical specifications and ROHS3 compliance certification, ensuring regulatory alignment with current manufacturing standards.

MAX802LCPA+ is available as a parametric equivalent but carries obsolete product status. Selection of this part should be limited to legacy system maintenance or applications where long-term supply continuity is not a requirement.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating, confirming compatibility with current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX690ACPA+ directly replace MAX703CPA+ in existing designs?

A: Yes. MAX690ACPA+ matches all critical electrical parameters including voltage threshold (4.65V), output configuration (push-pull, totem pole), reset logic (active low), and reset timeout (140ms minimum). Both parts use identical 8-DIP through-hole packaging and operate within the same temperature range (0°C ~ 70°C).

Q: What is the difference between MAX703CPA+ and MAX694CPA+?

A: Both parts are parametric equivalents with matching voltage threshold, output topology, reset characteristics, and package format. The primary distinction is the base product number (MAX703 versus MAX694). Electrical performance and mechanical compatibility are identical.

Q: Why is MAX802LCPA+ listed as obsolete?

A: MAX802LCPA+ carries obsolete product status from the manufacturer. While it maintains parametric equivalence with all specified electrical and mechanical parameters, new designs should prioritize active-status alternatives such as MAX690ACPA+ or MAX694CPA+ to ensure long-term supply availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (MAX690ACPA+, MAX694CPA+, and MAX802LCPA+) are ROHS3 compliant and REACH unaffected, confirming compatibility with current environmental regulations.

Q: Can these parts be used interchangeably in the same PCB layout?

A: Yes. All substitute parts use the 8-DIP (0.300", 7.62mm) through-hole package format with identical pin configurations, enabling direct PCB layout compatibility without modification.
