MAX174ACPI+ Equivalent & Substitute Parts

Part Overview

The MAX174ACPI+ is a 12-bit analog-to-digital converter manufactured by Analog Devices Inc./Maxim Integrated, designed for single-ended input data acquisition applications. This SAR architecture ADC features an internal reference, parallel data interface, and operates across multiple supply voltage configurations (5V, -12V, -15V). The device is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Alternative models become necessary when addressing specific inventory constraints, lead time requirements, or temperature grade specifications within the MAX174 product family.

Substitute Part Grouping Explanation

Substitution within the MAX174 family is determined by strict equivalence across all electrical and mechanical parameters. The MAX174ACPI+ and MAX174BCPI+ share identical functional specifications including 12-bit resolution, 125k sampling rate, single-ended input configuration, SAR architecture, internal reference, parallel data interface, and 28-DIP through-hole packaging. Both devices support identical supply voltage configurations (5V, -12V, -15V for analog and digital supplies) and operate within the 0°C to 70°C temperature range. The substitution relationship is based on complete parameter matching across resolution, sampling rate, input characteristics, data interface, architecture, reference implementation, supply requirements, package form factor, and mounting technology. No functional or electrical differences exist between these parts within their specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both MAX174ACPI+ and MAX174BCPI+ are Active product status devices with identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Selection between these parts should be based on inventory availability and lead time requirements. The MAX174ACPI+ currently maintains higher stock levels at 761 pieces, while MAX174BCPI+ is available with 685 pieces. Both devices carry MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special storage or handling requirements. For applications requiring immediate availability, MAX174ACPI+ is the preferred selection. For applications where alternative sourcing is acceptable, MAX174BCPI+ provides equivalent functional and compliance characteristics.

Frequently Asked Questions (FAQ)

Q: Are MAX174ACPI+ and MAX174BCPI+ electrically interchangeable? A: Yes. Both parts share identical electrical specifications including 12-bit resolution, 125k sampling rate, single-ended input configuration, SAR architecture, internal reference, parallel data interface, and supply voltage requirements (5V, -12V, -15V for both analog and digital supplies).

Q: Can these parts be used interchangeably in PCB designs? A: Yes. Both devices use identical 28-DIP (0.600", 15.24mm) through-hole packaging with 28-PDIP supplier device package designation. No PCB layout modifications are required for substitution.

Q: What is the difference between MAX174ACPI+ and MAX174BCPI+? A: These parts are functionally equivalent across all electrical and mechanical parameters. The designation difference reflects manufacturing lot or temperature grade classification within the MAX174 product family, but both operate identically within the specified 0°C to 70°C temperature range.

Q: Are both parts RoHS compliant? A: Yes. Both MAX174ACPI+ and MAX174BCPI+ are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

Q: Which part should I select for new designs? A: Either part is suitable for new designs. Selection should be based on current inventory availability and procurement lead times. Both maintain Active product status with equivalent compliance certifications.

Q: Do these parts require different handling or storage procedures? A: No. Both parts carry identical MSL Level 1 (Unlimited) rating, requiring no special moisture control or storage conditions during handling and assembly.
