MAX170CCPA Equivalent & Substitute Parts

Part Overview

The MAX170CCPA 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 125 kHz sampling rate and operates from dual supply voltages (5V and -12V to 15V). The device is packaged in an 8-pin DIP configuration suitable for through-hole mounting.

The MAX170CCPA is classified as an obsolete product. Locating equivalent or substitute components is necessary to support legacy system maintenance, board redesigns, or when original inventory becomes unavailable. Direct manufacturer substitutes with improved compliance status and active product support are available.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX170CCPA is determined by strict equivalence across the following critical parameters:

• Resolution and Sampling Rate: 12-bit resolution at 125 kHz sampling rate
• Input Configuration: Single-ended input with 1 ADC channel
• Data Interface: SPI protocol compatibility
• Architecture: SAR-based conversion
• Supply Voltage Requirements: Dual supply operation (5V and -12V to 15V)
• Package and Pinout: 8-DIP through-hole package with identical pin configuration
• Operating Temperature: 0°C to 70°C range

Two substitute parts meet these criteria: MAX170CCPA+ and MAX170DCPA+. Both are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications with the original MAX170CCPA. The primary differences are product status (both active versus obsolete) and RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

MAX170CCPA+ (Direct Manufacturer Substitute)

The MAX170CCPA+ is the primary substitute for the obsolete MAX170CCPA. It maintains complete electrical and mechanical compatibility while offering active product status and ROHS3 compliance certification. This part is suitable for new designs, board revisions, and legacy system support where regulatory compliance is required. Current inventory availability is 918 units.

MAX170DCPA+ (Parametric Equivalent)

The MAX170DCPA+ provides identical functional and electrical specifications to the MAX170CCPA. It is manufactured by the same supplier, carries active product status, and meets ROHS3 compliance requirements. This part serves as an alternative substitute when MAX170CCPA+ availability is constrained. Current inventory availability is 2,180 units.

Both substitute parts are suitable for direct replacement in existing MAX170CCPA applications without circuit modification, provided that the 8-DIP through-hole package and dual supply voltage requirements are compatible with the target application.

Frequently Asked Questions (FAQ)

Q: Can MAX170CCPA+ and MAX170DCPA+ be used interchangeably with MAX170CCPA?

A: Yes. Both substitute parts are electrically and mechanically equivalent to the MAX170CCPA. They share identical resolution (12-bit), sampling rate (125 kHz), input configuration (single-ended), data interface (SPI), supply voltage requirements (5V and -12V to 15V), and 8-DIP package specifications. Direct substitution is possible without circuit redesign.

Q: What is the difference between MAX170CCPA+ and MAX170DCPA+?

A: Both parts are functionally identical and meet the same electrical specifications. The primary distinction is product designation; however, both are active products with ROHS3 compliance. Selection between them may be based on inventory availability or supplier preference.

Q: Why is the original MAX170CCPA classified as obsolete?

A: The MAX170CCPA has reached end-of-life status. Analog Devices Inc./Maxim Integrated has transitioned production to the MAX170CCPA+ and MAX170DCPA+ variants, which offer improved compliance certifications and continued manufacturing support.

Q: Are there any compliance differences between the original and substitute parts?

A: Yes. The original MAX170CCPA is RoHS non-compliant, while both MAX170CCPA+ and MAX170DCPA+ are ROHS3 compliant. Both original and substitute parts maintain REACH Unaffected status. For applications subject to RoHS regulations, the substitute parts are required.

Q: What is the package configuration for these parts?

A: All three parts (MAX170CCPA, MAX170CCPA+, MAX170DCPA+) are packaged in an 8-pin DIP configuration with 0.300-inch (7.62mm) spacing, suitable for through-hole mounting on standard PCBs.

Q: Are there any temperature or supply voltage limitations for the substitutes?

A: No. The substitute parts maintain the same operating temperature range (0°C to 70°C) and dual supply voltage specifications (5V and -12V to 15V) as the original MAX170CCPA. No application modifications are required.
