MAX170DCPA Equivalent & Substitute Parts

Part Overview

The MAX170DCPA 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 MAX170DCPA is classified as obsolete. Locating equivalent or substitute parts is necessary to support legacy system maintenance, design updates, or when original inventory becomes unavailable. Direct manufacturer alternatives with improved compliance status and active product support are available.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX170DCPA is determined by electrical and mechanical parameter equivalence. All substitute parts must maintain identical specifications across the following critical parameters:

• 12-bit resolution
• 125 kHz sampling rate
• Single-ended input configuration
• SPI data interface
• SAR architecture with internal reference
• Dual supply voltage requirements (5V and -12V to 15V)
• Operating temperature range (0°C to 70°C)
• 8-DIP package footprint and through-hole mounting

Two substitute parts meet these criteria: MAX170DCPA+ and MAX170CCPA+. Both are manufactured by Analog Devices Inc./Maxim Integrated and share the same base product number (MAX170), ensuring functional and pin-level compatibility with the original MAX170DCPA.

Parameter Comparison

Engineering Selection Recommendations

Both MAX170DCPA+ and MAX170CCPA+ are functionally equivalent to the MAX170DCPA and provide direct substitution capability. The primary differentiators are product status and regulatory compliance:

MAX170DCPA+ is the direct successor to the original MAX170DCPA. It maintains identical electrical and mechanical specifications while offering active product support and RoHS3 compliance. This part is recommended for new designs and system updates requiring current manufacturing standards.

MAX170CCPA+ is a parametric equivalent offering the same functional performance and compliance status as MAX170DCPA+. Both substitute parts are actively manufactured and carry RoHS3 certification, making them suitable for applications requiring modern environmental and regulatory compliance.

Selection between MAX170DCPA+ and MAX170CCPA+ should be based on availability, lead time, and procurement requirements, as both parts are electrically and mechanically interchangeable with the original MAX170DCPA.

Frequently Asked Questions (FAQ)

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

A: Yes. Both substitute parts are pin-compatible and functionally equivalent. They maintain identical electrical specifications, package footprint, and mounting configuration. Direct board-level substitution is possible without circuit modifications.

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

A: Both parts are parametrically equivalent with identical electrical and mechanical specifications. The primary difference is the product designation suffix. Both are actively manufactured and RoHS3 compliant. Selection should be based on availability and procurement lead times.

Q: Why is the original MAX170DCPA classified as obsolete?

A: The MAX170DCPA has been superseded by newer variants (MAX170DCPA+ and MAX170CCPA+) that offer improved compliance status and active manufacturing support. The obsolete classification indicates that the original part is no longer in active production.

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

A: Yes. The original MAX170DCPA is RoHS non-compliant, while both MAX170DCPA+ and MAX170CCPA+ are RoHS3 compliant. All three parts are REACH unaffected and carry the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What packaging options are available for the substitute parts?

A: Both MAX170DCPA+ and MAX170CCPA+ are supplied in tube packaging. The original MAX170DCPA packaging specification was not provided. All parts use the same 8-DIP through-hole package footprint.

Q: Are there any temperature or supply voltage differences?

A: No. All three parts operate identically across the 0°C to 70°C temperature range and require the same dual supply voltages (5V and -12V to 15V for both analog and digital supplies).
