MAX174BCPI Equivalent & Substitute Parts

Part Overview

The MAX174BCPI 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 an internal reference, operating at a 125 kHz sampling rate in a 28-pin DIP package. The MAX174BCPI is currently classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitute parts for the MAX174BCPI are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Resolution: 12 bits
• Sampling Rate: 125 kHz
• Number of Inputs: 1
• Input Type: Single Ended
• Data Interface: Parallel
• Architecture: SAR
• Reference Type: Internal
• Supply Voltages: 5V, -12V, -15V (both analog and digital)
• Operating Temperature Range: 0°C to 70°C
• Package: 28-DIP (0.600", 15.24mm)
• Mounting Type: Through Hole

All identified substitutes maintain identical electrical specifications and physical packaging, ensuring direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The MAX174BCPI is obsolete and no longer in active production. For new designs or system replacements, MAX174BCPI+ or MAX174ACPI+ are the recommended alternatives. Both substitute parts maintain complete electrical and mechanical compatibility with the original MAX174BCPI while offering the following advantages:

• Active product status with ongoing manufacturer support
• ROHS3 compliance, meeting current environmental and regulatory standards
• Identical electrical performance across all specified parameters
• Direct pin-for-pin compatibility in 28-DIP through-hole applications

The choice between MAX174BCPI+ and MAX174ACPI+ depends on application-specific requirements not differentiated by the provided parameters. Both parts are functionally equivalent for the MAX174BCPI application.

Frequently Asked Questions (FAQ)

Q: Can MAX174BCPI+ or MAX174ACPI+ be used as direct replacements for MAX174BCPI?

A: Yes. Both substitute parts are electrically and mechanically identical to the MAX174BCPI across all specified parameters, including resolution, sampling rate, input configuration, supply voltages, operating temperature range, and 28-DIP package dimensions.

Q: What is the primary difference between the substitute parts and the original MAX174BCPI?

A: The MAX174BCPI is obsolete, while MAX174BCPI+ and MAX174ACPI+ are active products. The substitutes also carry ROHS3 compliance certification, whereas the original MAX174BCPI is RoHS non-compliant.

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

A: All three parts use identical 28-DIP (0.600", 15.24mm) through-hole packaging. The original MAX174BCPI is supplied in bulk packaging, while MAX174BCPI+ and MAX174ACPI+ are supplied in tube packaging.

Q: Do the substitute parts support the same supply voltage configurations?

A: Yes. Both MAX174BCPI+ and MAX174ACPI+ support identical analog and digital supply voltages of 5V, -12V, and -15V, matching the original MAX174BCPI specifications.

Q: What is the operating temperature range for these parts?

A: All three parts operate across the same temperature range of 0°C to 70°C.
