MAX192AEPP Equivalent & Substitute Parts

Part Overview

The MAX192AEPP is a 10-bit Data Acquisition System (DAS) with 8 channels, 133k sampling rate, and serial data interface manufactured by Analog Devices Inc./Maxim Integrated. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance, redesign, and procurement planning. The through-hole 20-DIP package and single-supply operation define its primary application scope in legacy and industrial data acquisition systems.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX192AEPP are identified based on strict electrical and mechanical parameter matching within the MAX192 product family. The substitution criteria are:

• Resolution: 10 bits (exact match required)
• Channel Count: 8 channels (exact match required)
• Sampling Rate: 133k samples per second (exact match required)
• Data Interface: Serial protocol compatibility (MICROWIRE™, QSPI™, SPI™ acceptable as serial variants)
• Package: 20-DIP through-hole form factor (exact match required)
• Operating Temperature: -40°C to 85°C (exact match required)
• Supply Configuration: Single supply operation (exact match required)

The MAX192AEPP+ qualifies as a direct substitute based on these parameters. Both parts share the same base product number (MAX192), identical electrical specifications, and compatible package geometry.

Parameter Comparison

Engineering Selection Recommendations

The MAX192AEPP+ is a direct functional equivalent to the MAX192AEPP. Both parts maintain identical electrical performance specifications across resolution, channel count, sampling rate, and operating temperature range. The primary distinction is regulatory compliance: the MAX192AEPP+ achieves ROHS3 compliance, whereas the original MAX192AEPP is RoHS non-compliant.

For new designs or systems requiring regulatory compliance with modern environmental standards, the MAX192AEPP+ is the appropriate selection. For legacy system maintenance where original specifications must be preserved without compliance upgrades, the MAX192AEPP remains the direct match. Both parts are classified as obsolete, requiring verification of current availability through authorized distributors.

Frequently Asked Questions (FAQ)

Q: Can the MAX192AEPP+ be used as a direct replacement for the MAX192AEPP in existing designs?

A: Yes. The MAX192AEPP+ is electrically and mechanically identical to the MAX192AEPP. All electrical parameters, pin configurations, and package dimensions are equivalent. The primary difference is RoHS compliance status.

Q: What does the "+" designation indicate on the MAX192AEPP+ part number?

A: The "+" suffix indicates a variant within the MAX192 product family, typically denoting updated compliance certifications or packaging specifications while maintaining core electrical functionality.

Q: Are there differences in data interface protocols between these parts?

A: The MAX192AEPP specifies "Serial" interface, while the MAX192AEPP+ lists "MICROWIRE™, QSPI™, Serial, SPI™" as supported protocols. Both parts support serial communication; the MAX192AEPP+ documentation provides expanded protocol compatibility information.

Q: What is the significance of the obsolete product status?

A: Obsolete status indicates these parts are no longer in active production. Availability is limited to existing inventory from authorized distributors. Long-term system support may require evaluation of current-generation alternatives from Analog Devices Inc./Maxim Integrated.

Q: Are the 20-DIP packages identical between both parts?

A: Yes. Both parts use the 20-DIP (0.300", 7.62mm) through-hole package with identical pin spacing and mechanical dimensions, ensuring direct PCB compatibility.

Q: What is the moisture sensitivity level for these components?

A: Both the MAX192AEPP and MAX192AEPP+ have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
