MAX174ACPI Equivalent & Substitute Parts

Part Overview

The MAX174ACPI is a 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for single-ended input data acquisition applications. This device features a successive approximation register (SAR) architecture with an internal reference, operating at a 125 kHz sampling rate in a 28-pin DIP package. The MAX174ACPI is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitute parts for the MAX174ACPI are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

• Resolution: 12 bits (exact match required)
• Sampling Rate: 125 kHz (exact match required)
• Number of Inputs: 1 (exact match required)
• Input Type: Single Ended (exact match required)
• Data Interface: Parallel (exact match required)
• Architecture: SAR (exact match required)
• Reference Type: Internal (exact match required)
• Supply Voltage (Analog & Digital): 5V, -12V, -15V (exact match required)
• Operating Temperature Range: 0°C to 70°C (exact match required)
• Package: 28-DIP (exact match required)
• Mounting Type: Through Hole (exact match required)

Parts meeting all these criteria are classified as direct equivalents or parametric equivalents based on product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both MAX174ACPI+ and MAX174BCPI+ are functionally equivalent to the MAX174ACPI across all electrical and mechanical parameters. The primary differentiators are product status and regulatory compliance:

MAX174ACPI+ is the direct successor to the MAX174ACPI, maintaining identical electrical specifications while achieving ROHS3 compliance and active product status. This part is suitable for new designs and ongoing production requiring modern compliance certifications.

MAX174BCPI+ is a parametric equivalent offering identical electrical and mechanical characteristics with ROHS3 compliance and active product status. This part provides an alternative source for applications requiring the same functional performance.

Both substitute parts are available in tube packaging and maintain full compatibility with existing MAX174ACPI circuit designs without modification.

Frequently Asked Questions (FAQ)

Q: Can MAX174ACPI+ and MAX174BCPI+ be used interchangeably with MAX174ACPI?

A: Yes. Both parts meet all electrical and mechanical parameter requirements for direct substitution. The 28-DIP package, pin configuration, and functional specifications are identical across all three parts.

Q: What is the difference between MAX174ACPI+ and MAX174BCPI+?

A: Both parts are parametric equivalents with identical electrical specifications. The primary difference is the product designation suffix. Both are ROHS3 compliant and actively manufactured.

Q: Why is the MAX174ACPI classified as obsolete?

A: The MAX174ACPI is no longer in active production. MAX174ACPI+ and MAX174BCPI+ are the current active alternatives that maintain full functional equivalence.

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

A: No. All three parts use the 28-DIP (0.600", 15.24mm) package with through-hole mounting. The only packaging difference is that MAX174ACPI+ and MAX174BCPI+ are supplied in tube packaging, while MAX174ACPI was supplied in bulk.

Q: Do these parts require any circuit modifications for substitution?

A: No circuit modifications are required. The parts are pin-compatible and functionally equivalent, allowing direct replacement in existing designs.

Q: What is the inventory status for substitute parts?

A: MAX174ACPI+ has 761 pieces in stock. MAX174BCPI+ has 685 pieces in stock. Both are available as new original components.
