MAX170CEPA Equivalent & Substitute Parts

Part Overview

The MAX170CEPA 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 sampling rate of 125 kSPS and communicating via SPI interface. The device is packaged in an 8-PDIP through-hole configuration and operates across the temperature range of -40°C to 85°C.

The MAX170CEPA is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance or redesigns where component availability is constrained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX170CEPA is determined by strict equivalence across the following critical parameters:

• Resolution: 12 bits
• Sampling Rate: 125 kSPS
• Input Configuration: Single-ended, 1 input
• Data Interface: SPI
• Architecture: SAR with internal reference
• Supply Voltage Compatibility: 5V, -12V ~ 15V (both analog and digital)
• Operating Temperature Range: -40°C to 85°C
• Package: 8-DIP through-hole form factor

The MAX170DEPA+ meets all these parameters identically, establishing it as a parametric equivalent. The primary distinction between the main part and its substitute lies in product status and compliance certifications rather than electrical or mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX170DEPA+ is the direct parametric equivalent to the MAX170CEPA. Both devices are electrically and mechanically identical across all functional specifications. The MAX170DEPA+ is the preferred selection for new designs and component replacement due to its active product status and ROHS3 compliance certification. The MAX170CEPA, being obsolete and RoHS non-compliant, should be replaced with the MAX170DEPA+ in applications where regulatory compliance and long-term supply availability are required.

For legacy systems currently using the MAX170CEPA, the MAX170DEPA+ provides drop-in compatibility without circuit redesign, as both devices share identical pinout, electrical characteristics, and package dimensions.

Frequently Asked Questions (FAQ)

Q: Can the MAX170DEPA+ directly replace the MAX170CEPA in existing designs?

A: Yes. The MAX170DEPA+ is a parametric equivalent with identical electrical specifications, pinout, and package dimensions. No circuit modifications are required for substitution.

Q: What is the primary difference between these two parts?

A: The MAX170CEPA is obsolete and RoHS non-compliant, while the MAX170DEPA+ is an active product with ROHS3 compliance. All functional and mechanical parameters are identical.

Q: Are there any compatibility concerns with the 8-DIP through-hole package?

A: No. Both parts use the same 8-DIP (0.300", 7.62mm) through-hole package. PCB footprints and mounting procedures are identical.

Q: Does the MAX170DEPA+ support the same supply voltage range?

A: Yes. Both devices support identical analog and digital supply voltages of 5V and -12V ~ 15V, with the same operating temperature range of -40°C to 85°C.

Q: Why is the MAX170CEPA listed as obsolete?

A: The MAX170CEPA has been discontinued by the manufacturer. The MAX170DEPA+ represents the current active equivalent in the MAX170 product line.
