Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX502ACWG+ is determined by the following critical parameters: resolution (12 bits), converter count (1 DAC), output configuration (voltage-buffered), interface type (parallel), package format (24-SOIC), and thermal operating range (0°C to 70°C). The MAX507BCWG+ qualifies as a manufacturer-recommended substitute based on matching these core electrical and mechanical specifications. The primary distinction between these parts lies in the reference type configuration: the MAX502ACWG+ requires an external reference, while the MAX507BCWG+ incorporates an internal reference. Both devices maintain identical resolution, settling time, architecture, and physical packaging, ensuring functional compatibility within applications where reference source flexibility is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the MAX502ACWG+ and MAX507BCWG+ maintain active product status and full ROHS3 compliance, ensuring long-term availability and environmental regulatory adherence. The MAX507BCWG+ offers higher inventory availability (3100 units versus 774 units), which may provide supply chain advantages. Selection between these parts should be based on circuit design requirements: applications requiring external reference voltage control should specify the MAX502ACWG+, while designs benefiting from integrated reference functionality should utilize the MAX507BCWG+. Both devices are suitable for production deployment without additional qualification testing, provided the reference configuration aligns with system architecture.

Frequently Asked Questions (FAQ)

Q: Can MAX507BCWG+ directly replace MAX502ACWG+ in existing designs?

A: Direct replacement is possible only if the circuit design accommodates the internal reference of the MAX507BCWG+. The external reference requirement of the MAX502ACWG+ differs fundamentally from the internal reference architecture of the MAX507BCWG+. PCB layout and reference circuitry modifications may be necessary.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 24-SOIC package with 0.295" width (7.50mm), ensuring identical PCB footprints and mounting compatibility.

Q: What is the significance of the INL/DNL difference?

A: The MAX502ACWG+ specifies ±0.75 LSB maximum INL and ±1 LSB maximum DNL, while the MAX507BCWG+ specifies ±1 LSB for both parameters. This represents a minor linearity difference; the MAX502ACWG+ offers tighter integral nonlinearity performance.

Q: Do both parts require the same supply voltage range?

A: Both require ±11.4V to 15.75V for analog supply. The MAX507BCWG+ additionally requires a digital supply of 11.4V to 15.75V, whereas the MAX502ACWG+ does not specify a separate digital supply requirement.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99, with identical moisture sensitivity levels (MSL 1 - Unlimited).
