Substitute Part Grouping Explanation

Substitution of the MAX504ESD is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is the MAX504ESD+, which maintains identical functional specifications including 10-bit resolution, single DAC channel, SPI interface, R-2R architecture, and identical supply voltage requirements (±5V analog, 5V digital). Both parts share the same 14-SOIC package footprint and operating temperature range of -40°C to 85°C.

The substitution is valid based on the following key parameters:

• Resolution: 10 bits (identical)
• DAC channels: 1 (identical)
• Output type: Voltage - Buffered (identical)
• Data interface: SPI (identical)
• Reference configuration: External, Internal (identical)
• Settling time: 25µs typical (identical)
• INL/DNL specifications: ±0.5 LSB / ±1 LSB (identical)
• Architecture: R-2R (identical)
• Supply voltages: ±5V analog, 5V digital (identical)
• Package: 14-SOIC (identical)
• Temperature range: -40°C to 85°C (identical)

Engineering Selection Recommendations

The MAX504ESD+ is the direct functional equivalent of the MAX504ESD. Selection between these parts should be based on product status and regulatory compliance requirements.

The MAX504ESD is classified as obsolete, indicating discontinued manufacturing and limited long-term availability. The MAX504ESD+ maintains active product status with current manufacturing support from Analog Devices Inc./Maxim Integrated.

For new designs and systems requiring long-term component availability, the MAX504ESD+ is the appropriate selection. This part provides identical electrical and mechanical performance while offering ROHS3 compliance, compared to the RoHS non-compliant status of the original MAX504ESD. Both parts maintain REACH Unaffected status and identical moisture sensitivity classification (MSL 1 - Unlimited).

The 14-SOIC surface mount package is identical between both parts, ensuring direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can MAX504ESD+ be used as a direct replacement for MAX504ESD?

A: Yes. The MAX504ESD+ is electrically and mechanically equivalent to the MAX504ESD. All functional parameters including resolution, settling time, linearity specifications, supply voltages, and package dimensions are identical. Direct substitution is possible without circuit modifications.

Q: What is the primary difference between MAX504ESD and MAX504ESD+?

A: The primary differences are product status and regulatory compliance. The MAX504ESD is obsolete with RoHS non-compliant status, while the MAX504ESD+ is an active product with ROHS3 compliance. Both parts are functionally identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the identical 14-SOIC package with 0.154" width (3.90mm). Pinout and PCB footprint are identical, enabling direct component substitution without layout changes.

Q: What is the moisture sensitivity level for these parts?

A: Both the MAX504ESD and MAX504ESD+ have a Moisture Sensitivity Level (MSL) of 1, classified as Unlimited. This indicates minimal moisture sensitivity and standard handling requirements.

Q: Are these parts REACH compliant?

A: Both parts maintain REACH Unaffected status, indicating they are not subject to REACH regulatory restrictions.

Q: Why should I choose MAX504ESD+ over MAX504ESD for new designs?

A: The MAX504ESD+ should be selected for new designs because it maintains active product status with ongoing manufacturing support from Analog Devices Inc./Maxim Integrated. The MAX504ESD is obsolete and subject to availability constraints. Additionally, the MAX504ESD+ provides ROHS3 compliance, meeting current environmental and regulatory standards.
