MAX166BCPP+ Equivalent & Substitute Parts

Part Overview

The MAX166BCPP+ is an 8-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for single-channel data acquisition applications. This device features a successive approximation register (SAR) architecture with a 200 kHz sampling rate and operates from a single 5V supply. The MAX166BCPP+ is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. Substitute parts within the MAX166 family maintain identical electrical and mechanical specifications while offering improved product status and availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the MAX166 family is determined by strict parametric equivalence across all electrical and mechanical specifications. The MAX166BCPP+, MAX166ACPP+, and MAX166CCPP+ share identical core parameters: 8-bit resolution, 200 kHz sampling rate, single differential input, SAR architecture, parallel data interface, 5V dual supply operation, and 20-DIP through-hole packaging. These parts are mechanically and electrically interchangeable at the circuit level.

The primary differentiator among these parts is product status and temperature grade designation embedded in the part number suffix. The MAX166BCPP+ (B-grade, obsolete) can be directly replaced by MAX166ACPP+ (A-grade, active) or MAX166CCPP+ (C-grade, active) without circuit modification, provided the application temperature range remains within 0°C to 70°C.

Parameter Comparison

Engineering Selection Recommendations

For new designs or production continuity, MAX166ACPP+ and MAX166CCPP+ are preferred over the obsolete MAX166BCPP+. Both active alternatives maintain full parametric equivalence and offer superior long-term availability. Selection between MAX166ACPP+ and MAX166CCPP+ depends on procurement requirements and inventory availability, as both parts are electrically and mechanically identical.

All three parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications. The unlimited MSL rating (Level 1) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can MAX166ACPP+ or MAX166CCPP+ be used as direct replacements for MAX166BCPP+ without circuit modification?

A: Yes. All three parts share identical electrical specifications (8-bit resolution, 200 kHz sampling rate, 5V dual supply, differential input, SAR architecture) and mechanical specifications (20-DIP through-hole package). No circuit redesign is required for substitution.

Q: What is the difference between MAX166ACPP+, MAX166BCPP+, and MAX166CCPP+?

A: The letter designation (A, B, C) indicates the temperature grade and product status. MAX166BCPP+ is obsolete, while MAX166ACPP+ and MAX166CCPP+ are active products. All three operate within the same 0°C to 70°C temperature range and are electrically equivalent.

Q: Are there any packaging differences between these parts?

A: No. All three parts use identical 20-DIP (0.300", 7.62mm) through-hole packaging with the same pin configuration and mechanical footprint.

Q: Why is MAX166BCPP+ listed as obsolete?

A: Product obsolescence reflects manufacturer lifecycle decisions. Active alternatives (MAX166ACPP+, MAX166CCPP+) provide equivalent functionality with improved long-term support and availability.

Q: Do these parts require different PCB layouts or socket types?

A: No. The identical 20-DIP package and pin configuration allow direct socket compatibility across all three parts.

Q: Are compliance certifications identical across all three parts?

A: Yes. MAX166BCPP+, MAX166ACPP+, and MAX166CCPP+ all maintain ROHS3 compliance, REACH unaffected status, and Level 1 MSL rating.
