Critical Parameters for Substitution:

• Resolution: 12 bits
• Number of DAC channels: 1
• Output configuration: Voltage - Buffered
• Data interface: SPI
• Supply voltages: 5V analog and digital
• Settling time: 20µs (Typ)
• INL/DNL linearity: ±1 LSB (Max)
• Architecture: R-2R
• Operating temperature range: -40°C ~ 85°C
• Package: 16-SSOP surface mount

Substitute parts must maintain identical electrical performance specifications and physical package compatibility to ensure direct replacement capability without circuit redesign.

Engineering Selection Recommendations

MAX5120BEEE+ (Direct Substitute - Recommended)

The MAX5120BEEE+ is the primary substitute for the MAX5120BEEE. Both parts share identical electrical specifications and package configuration. The MAX5120BEEE+ is currently in active production status, ensuring long-term availability. The MAX5120BEEE+ carries ROHS3 compliance certification, whereas the original MAX5120BEEE is RoHS non-compliant. This upgrade path supports regulatory compliance requirements for new designs and manufacturing operations.

MAX5122BEEE+ (Parametric Equivalent)

The MAX5122BEEE+ maintains all critical electrical parameters and package specifications identical to the MAX5120BEEE. This part is classified as obsolete but carries ROHS3 compliance. The MAX5122BEEE+ represents a parametric equivalent suitable for applications where the base product number difference does not impact system requirements. Availability may be limited due to obsolete status.

Frequently Asked Questions (FAQ)

Q: Can MAX5120BEEE+ be used as a direct replacement for MAX5120BEEE?

A: Yes. The MAX5120BEEE+ is a direct substitute. Both parts feature identical 12-bit resolution, single DAC channel, SPI interface, 5V supply requirements, 20µs settling time, ±1 LSB linearity, R-2R architecture, and 16-SSOP package configuration. The primary difference is product status and RoHS compliance level.

Q: What is the difference between MAX5120BEEE and MAX5120BEEE+?

A: The MAX5120BEEE+ is the active production variant of the MAX5120BEEE. Electrical specifications are identical. The MAX5120BEEE+ is ROHS3 compliant, while the MAX5120BEEE is RoHS non-compliant. The MAX5120BEEE+ is supplied in tube packaging.

Q: Is MAX5122BEEE+ compatible with MAX5120BEEE applications?

A: Yes. The MAX5122BEEE+ is a parametric equivalent with identical electrical performance and package specifications. All critical parameters including resolution, DAC count, output type, interface, supply voltages, settling time, linearity, and operating temperature range match the MAX5120BEEE. The base product number differs, but functional compatibility is maintained.

Q: Are there any package or pinout differences between these parts?

A: No. All three parts use the 16-SSOP (0.154", 3.90mm Width) surface mount package with identical pinout and mechanical dimensions. Direct PCB substitution is supported without layout modifications.

Q: What is the impact of RoHS compliance differences?

A: The MAX5120BEEE is RoHS non-compliant, while MAX5120BEEE+ and MAX5122BEEE+ are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the compliant variants (MAX5120BEEE+ or MAX5122BEEE+) must be selected.

Q: Which substitute part should be selected for new designs?

A: MAX5120BEEE+ is the recommended choice for new designs. It is in active production status, ensuring supply chain continuity, and carries ROHS3 compliance certification. Electrical specifications are identical to the original MAX5120BEEE.
