Critical Parameters for Substitution:

• Resolution: 16 Bit
• Number of D/A Converters: 1
• Output Type: Voltage - Unbuffered
• Data Interface: SPI
• Reference Type: External
• Settling Time: 1µs (Typ)
• Supply Voltages: 5V Analog, 5V Digital
• INL/DNL: ±0.5, ±0.5 LSB
• Architecture: R-2R
• Operating Temperature: -40°C ~ 85°C
• Package: 10-TFSOP, 10-MSOP

All identified substitutes match these parameters completely. Differences exist only in product status and compliance certifications.

Engineering Selection Recommendations

MAX5442AEUB+ (Direct Manufacturer Equivalent): This part is the direct equivalent of the MAX5442AEUB with identical electrical and mechanical specifications. The primary advantage is active product status and ROHS3 compliance. This part is suitable for new designs and replacement applications where RoHS compliance is required. Packaging is supplied in tube format.

MAX5442BEUB+ (Parametric Equivalent): This part maintains all critical electrical and mechanical parameters identical to the MAX5442AEUB. It is also active and ROHS3 compliant. Selection between MAX5442AEUB+ and MAX5442BEUB+ depends on specific application requirements and availability. Both parts are functionally interchangeable based on provided specifications.

For applications currently using the obsolete MAX5442AEUB, either MAX5442AEUB+ or MAX5442BEUB+ provides direct substitution with the added benefit of active product status and modern compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can MAX5442AEUB+ and MAX5442BEUB+ be used interchangeably with MAX5442AEUB?

A: Yes. All three parts share identical electrical parameters including 16-bit resolution, 1µs settling time, SPI interface, external reference input, 5V supply requirements, and ±0.5 LSB INL/DNL specifications. Package and mounting type are identical. Substitution is direct.

Q: What is the difference between MAX5442AEUB+ and MAX5442BEUB+?

A: Based on provided specifications, both parts are parametric equivalents with identical electrical and mechanical characteristics. The difference lies in the part designation suffix (A vs. B), which typically indicates different temperature grades or manufacturing batches within the same product family. Both are active and ROHS3 compliant.

Q: Why is the original MAX5442AEUB obsolete?

A: The MAX5442AEUB is classified as obsolete by the manufacturer. The active equivalents MAX5442AEUB+ and MAX5442BEUB+ provide continued access to this functionality with current product support and compliance certifications.

Q: Are there any package or pinout differences?

A: No. All three parts use the same 10-TFSOP/10-MSOP package with 0.118" width (3.00mm). Pinout and PCB footprint are identical, enabling direct board-level substitution.

Q: What compliance certifications apply to the substitute parts?

A: Both MAX5442AEUB+ and MAX5442BEUB+ are ROHS3 compliant and REACH unaffected. The original MAX5442AEUB is RoHS non-compliant. For applications requiring RoHS compliance, the substitute parts are required.
