MAX158ACPI Equivalent & Substitute Parts

Part Overview

The MAX158ACPI is an 8-bit flash analog-to-digital converter manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring parallel interface output. This component features 8 single-ended inputs, internal voltage reference, and a 400 kSPS sampling rate in a 28-DIP through-hole package. The MAX158ACPI is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX158ACPI are identified based on strict parametric equivalence within the MAX158 product family. The following electrical and mechanical parameters determine substitution validity:

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

Substitute parts maintain identical functional specifications and pinout compatibility. Differences in product status, packaging format (tube vs. standard), and RoHS compliance status do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MAX158ACPI, MAX158ACPI+, and MAX158BCPI+—are electrically and mechanically equivalent for direct substitution in applications requiring 8-bit, 400 kSPS flash ADC functionality with parallel interface and 5V operation.

MAX158BCPI+ is the preferred selection for new designs and long-term procurement due to its active product status, ensuring continued manufacturer support and availability. This part also carries ROHS3 compliance certification.

MAX158ACPI+ serves as an intermediate option, offering ROHS3 compliance while maintaining obsolete product status. This part is available in tube packaging.

MAX158ACPI, the original reference part, is classified as obsolete and carries RoHS non-compliant status. Selection of this part should be limited to legacy system maintenance where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Are MAX158ACPI, MAX158ACPI+, and MAX158BCPI+ pin-for-pin compatible?

A: Yes. All three parts share identical pinout, package dimensions (28-DIP), and electrical specifications. Direct socket substitution is supported without circuit modification.

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

A: The primary differences are packaging format (standard vs. tube) and RoHS compliance status (non-compliant vs. ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Why is MAX158BCPI+ recommended over MAX158ACPI?

A: MAX158BCPI+ maintains active product status, ensuring ongoing manufacturer support, documentation updates, and supply chain availability. The MAX158ACPI is obsolete, limiting long-term procurement options.

Q: Can MAX158BCPI+ replace MAX158ACPI in existing designs?

A: Yes. MAX158BCPI+ is a direct functional and mechanical equivalent. No design changes, PCB modifications, or firmware updates are required for substitution.

Q: What does ROHS3 compliance mean for component selection?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. This certification is relevant for applications subject to environmental or regulatory requirements.

Q: Are there any temperature range differences between these parts?

A: No. All three parts operate across the identical temperature range of 0°C to 70°C.
