Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX154ACWG is determined by strict equivalence across the following critical parameters:

• Resolution & Sampling Rate: 8-bit resolution at 400 kSPS
• Input Configuration: 4 single-ended inputs with multiplexer and sample-and-hold architecture
• Data Interface: Parallel output format
• Supply Voltages: 5V analog and digital supplies
• Package & Pinout: 24-SOIC form factor with identical mechanical dimensions
• Functional Architecture: Flash ADC with internal reference and selectable address features

The MAX154BCWG+ meets all these criteria as a parametric equivalent, with the primary distinction being product status and compliance certification.

Engineering Selection Recommendations

The MAX154BCWG+ is the direct parametric equivalent for the obsolete MAX154ACWG. Selection between these parts should be based on the following factors:

For Legacy System Maintenance: The MAX154ACWG remains available in inventory (2478 pcs) and maintains identical electrical and mechanical specifications. This part is suitable for direct replacement in existing designs where component-level compatibility is the sole requirement.

For New Designs and Long-Term Support: The MAX154BCWG+ is the recommended choice due to its active product status and ROHS3 compliance certification. This part ensures supply chain continuity and meets current environmental and regulatory standards. The MAX154BCWG+ is available in tube packaging (3200 pcs in stock) and carries REACH unaffected status, matching the original part's regulatory profile.

Both parts share identical electrical performance, pinout, and package dimensions, enabling direct substitution without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the MAX154BCWG+ directly replace the MAX154ACWG in existing designs?

A: Yes. The MAX154BCWG+ is a parametric equivalent with identical resolution, sampling rate, input configuration, supply voltages, and 24-SOIC package dimensions. No circuit modifications are required for direct substitution.

Q: What is the primary difference between these two parts?

A: The MAX154ACWG is classified as obsolete, while the MAX154BCWG+ maintains active product status. The MAX154BCWG+ also carries ROHS3 compliance certification, whereas the MAX154ACWG is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with packaging format?

A: The MAX154ACWG is supplied in bulk packaging, while the MAX154BCWG+ is supplied in tube packaging. Both use the same 24-SOIC form factor with identical pinout and mechanical dimensions. Packaging format does not affect electrical compatibility or board-level integration.

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

A: The MAX154BCWG+ is the appropriate choice for new designs. Its active product status ensures long-term availability, and ROHS3 compliance meets current regulatory requirements for commercial and industrial applications.

Q: Are the supply voltage requirements identical?

A: Yes. Both parts require 5V analog supply and 5V digital supply, with identical operating temperature range of 0°C to 70°C.
