MAX158BCPI Equivalent & Substitute Parts

Part Overview

The MAX158BCPI is an 8-bit flash analog-to-digital converter manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring high-speed conversion. This device features 8 single-ended inputs, a 400 kSPS sampling rate, and internal voltage reference, operating from dual 5V supplies in a 28-pin DIP package.

The MAX158BCPI is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for legacy systems and new designs requiring this performance class.

Substitute Part Grouping Explanation

Substitution for the MAX158BCPI is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for functional interchangeability:

• Resolution: 8 bits
• Sampling rate: 400 kSPS
• Input channels: 8 single-ended
• Data interface: Parallel
• Architecture: Flash ADC
• Reference: Internal
• Supply voltages: 5V analog and digital
• Package: 28-DIP through-hole
• Operating temperature range: 0°C to 70°C

Substitute parts are identified within the MAX158 base product family. Variations in product status and compliance certifications do not affect electrical or mechanical compatibility when all parameters listed above are matched.

Engineering Selection Recommendations

MAX158BCPI+ is the primary substitute for new designs and ongoing production. This part maintains full electrical and mechanical compatibility with the original MAX158BCPI while offering active product status and ROHS3 compliance. The transition from non-compliant to compliant RoHS status reflects current manufacturing standards without affecting circuit performance or pin compatibility.

MAX158ACPI+ provides an alternative substitute with identical electrical specifications and ROHS3 compliance. Although classified as obsolete, this part remains functionally equivalent and may be selected based on inventory availability and supply chain considerations.

Both substitute parts are packaged in tubes and maintain the 28-PDIP through-hole form factor, ensuring direct board-level compatibility with existing MAX158BCPI designs.

Frequently Asked Questions (FAQ)

Q: Can MAX158BCPI+ be used as a direct replacement for MAX158BCPI?

A: Yes. MAX158BCPI+ is electrically and mechanically identical to MAX158BCPI across all specified parameters. The primary difference is product status (active vs. obsolete) and RoHS3 compliance certification. Pin configuration, signal timing, and supply requirements are unchanged.

Q: What is the difference between MAX158BCPI and MAX158ACPI+?

A: Both parts are functionally equivalent with identical electrical specifications and 28-DIP packaging. The difference lies in product status and RoHS compliance. MAX158ACPI+ is ROHS3 compliant, while MAX158BCPI is not. Both are suitable for circuit substitution.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist when substituting within this group. All three parts share identical resolution, sampling rate, input configuration, supply voltages, and package specifications. Board layout, PCB traces, and socket designs require no modification.

Q: Does packaging format affect substitution?

A: Packaging format (tube vs. other formats) does not affect electrical or mechanical compatibility. All substitute parts use the same 28-DIP through-hole package. Packaging format relates only to order quantity and handling, not circuit performance.

Q: Which substitute should be selected for new designs?

A: MAX158BCPI+ is recommended for new designs due to active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. MAX158ACPI+ may be selected based on specific supply chain or inventory requirements, as it provides identical electrical performance.
