Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX520BCPE is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Count: 8-bit resolution with 4 independent DAC channels
• Output Configuration: Voltage-mode unbuffered output
• Interface Protocol: I2C digital communication
• Reference Architecture: External reference with R-2R resistor ladder
• Supply Voltage Requirements: Dual 5V supplies (analog and digital)
• Electrical Performance: Settling time of 2µs (typical), INL/DNL of ±1 LSB maximum
• Thermal Operating Range: 0°C to 70°C
• Physical Package: 16-pin DIP form factor with 0.300" (7.62mm) pitch for through-hole mounting

The MAX520ACPE+ meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The MAX520ACPE+ is the direct parametric equivalent for the obsolete MAX520BCPE. Both components share identical electrical specifications, pin configuration, and functional characteristics across all critical parameters.

The MAX520ACPE+ offers the additional advantage of active product status, ensuring ongoing manufacturer support and supply chain availability. This substitute also meets ROHS3 compliance requirements, whereas the MAX520BCPE is non-compliant. For new designs or long-term production requirements, the MAX520ACPE+ is the appropriate selection.

Both components maintain identical packaging specifications (16-DIP through-hole), allowing direct mechanical and electrical substitution without circuit board redesign or layout modification.

Frequently Asked Questions (FAQ)

Q: Can the MAX520ACPE+ be used as a direct replacement for the MAX520BCPE in existing designs?

A: Yes. The MAX520ACPE+ is electrically and mechanically equivalent to the MAX520BCPE. All electrical parameters, pin assignments, and package dimensions are identical. No circuit modifications are required.

Q: What is the difference between the MAX520BCPE and MAX520ACPE+ part numbers?

A: The primary differences are product status and compliance certification. The MAX520BCPE is obsolete and RoHS non-compliant. The MAX520ACPE+ is an active product with ROHS3 compliance. Electrical and functional specifications are identical.

Q: Are there any packaging differences between these two parts?

A: Both components use the same 16-pin DIP package with 0.300" (7.62mm) pitch. The MAX520BCPE is supplied in standard packaging, while the MAX520ACPE+ is supplied in tube packaging. Both are suitable for through-hole mounting without modification.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching resolution (8-bit), channel count (4 DACs), output type (voltage-unbuffered), interface protocol (I2C), reference architecture (external R-2R), supply voltages (5V dual), settling time (2µs typical), and operating temperature range (0°C to 70°C).

Q: Is the MAX520ACPE+ suitable for new product designs?

A: Yes. The MAX520ACPE+ is an active product with current manufacturer support and ROHS3 compliance, making it appropriate for new designs requiring 8-bit, 4-channel DAC functionality with I2C interface and external reference capability.
