MAX176ACPA Equivalent & Substitute Parts

Part Overview

The MAX176ACPA is a 12-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for single-ended input data acquisition applications. It features a Successive Approximation Register (SAR) architecture with a 250 kSPS sampling rate and SPI digital interface. The device operates from dual supply voltages (5V and -12V to 15V) and is housed in an 8-pin DIP package for through-hole mounting.

The MAX176ACPA is classified as obsolete, making equivalent substitute parts necessary for ongoing production, maintenance, and design updates. Direct replacements and parametric equivalents are available from the same manufacturer with improved compliance status and active product support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX176ACPA are identified based on strict parameter matching across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

• Resolution and Sampling Rate: All substitutes maintain 12-bit resolution and 250 kSPS sampling rate
• Input Configuration: Single-ended input with 1 ADC channel
• Digital Interface: SPI protocol compatibility
• Architecture: SAR-based conversion
• Supply Voltages: Identical dual supply voltage requirements (5V and -12V to 15V)
• Operating Temperature: 0°C to 70°C range
• Package and Pinout: 8-DIP through-hole package with identical mechanical dimensions

Two substitute parts meet these criteria:

1. MAX176ACPA+ (Direct Manufacturer Equivalent): Identical part number with tape-and-reel packaging variant, active product status
2. MAX176BCPA+ (Parametric Equivalent): Temperature-graded variant with identical electrical specifications, active product status

Engineering Selection Recommendations

MAX176ACPA+ (Direct Manufacturer Equivalent)

The MAX176ACPA+ is the primary substitute for the obsolete MAX176ACPA. This part maintains complete electrical and mechanical compatibility while offering active product status and ROHS3 compliance. The primary distinction is packaging format (tube instead of bulk), which does not affect electrical performance or pinout compatibility. This variant is suitable for all applications currently using the MAX176ACPA.

MAX176BCPA+ (Parametric Equivalent)

The MAX176BCPA+ provides an alternative substitute with identical electrical specifications and ROHS3 compliance. As a temperature-graded variant within the same product family, it maintains full compatibility with the MAX176ACPA across all critical parameters. This part is appropriate for applications requiring active product support and regulatory compliance.

Both substitutes are manufactured by Analog Devices Inc./Maxim Integrated and carry REACH Unaffected and EAR99 export classification status, matching the original part's regulatory profile.

Frequently Asked Questions (FAQ)

Q: Can MAX176ACPA+ be used as a direct replacement for MAX176ACPA?

A: Yes. The MAX176ACPA+ is electrically and mechanically identical to the MAX176ACPA. The "+" suffix indicates tape-and-reel packaging. All electrical parameters, pinout, and functional specifications are identical. The primary advantage is active product status and ROHS3 compliance.

Q: What is the difference between MAX176ACPA+ and MAX176BCPA+?

A: Both parts are parametric equivalents with identical electrical specifications, sampling rate, resolution, and supply voltage requirements. The difference lies in temperature grading and product designation. Both are active products with ROHS3 compliance and are suitable for the 0°C to 70°C operating range specified for the original MAX176ACPA.

Q: Are the substitute parts pin-compatible with the original MAX176ACPA?

A: Yes. All substitute parts use the 8-DIP package with identical pinout and mechanical dimensions (0.300", 7.62mm). Through-hole mounting compatibility is maintained across all variants.

Q: What is the impact of the packaging change from bulk to tube?

A: Packaging format (bulk versus tube) does not affect electrical performance, functionality, or circuit compatibility. The change is purely logistical and relates to supply chain handling. The device itself remains identical.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both MAX176ACPA+ and MAX176BCPA+ are ROHS3 compliant, whereas the original MAX176ACPA is RoHS non-compliant. This represents an improvement in regulatory compliance for new designs and production runs.

Q: Can I use these substitutes in legacy systems currently running MAX176ACPA?

A: Yes. The electrical and mechanical compatibility of MAX176ACPA+ and MAX176BCPA+ with the original MAX176ACPA makes them suitable for retrofit and replacement in existing systems without circuit modification.
