MAX133CPL Equivalent & Substitute Parts

Part Overview

The MAX133CPL is a 3.75-digit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring moderate resolution and sampling rates. This component features three input channels, dual ±5V supply operation, and through-hole mounting in a 40-DIP package. The MAX133CPL is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX133CPL is determined by strict equivalence across the following critical parameters:

• Resolution and Sampling Rate: The substitute must maintain 3.75-digit resolution and 20 samples-per-second sampling rate to ensure functional compatibility with existing signal processing chains.
• Channel Configuration: Three-channel input architecture is mandatory for direct replacement.
• Supply Voltage: Dual ±5V operation is required; no alternative supply configurations are acceptable.
• Package and Pinout: 40-DIP through-hole package with identical pin assignments ensures mechanical and electrical compatibility with existing PCB layouts.
• Operating Temperature Range: 0°C to 70°C specification must be maintained.

The MAX133CPL+ is identified as a direct substitute based on identical electrical specifications, identical package configuration, and compatible pinout. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX133CPL+ is the direct equivalent substitute for the obsolete MAX133CPL. Both components share identical electrical specifications, pinout, and package configuration, enabling direct replacement without circuit modification.

The MAX133CPL+ offers the additional advantage of active product status, ensuring continued availability and manufacturing support. The MAX133CPL+ also achieves ROHS3 compliance, whereas the original MAX133CPL is RoHS non-compliant. This distinction is significant for applications subject to environmental regulations or procurement policies requiring RoHS-compliant components.

Both parts maintain identical REACH status (REACH Unaffected) and moisture sensitivity classification (MSL 1, Unlimited), confirming compatibility in storage, handling, and operational environments.

Frequently Asked Questions (FAQ)

Q: Can the MAX133CPL+ be used as a direct replacement for the MAX133CPL in existing designs?

A: Yes. The MAX133CPL+ is electrically and mechanically identical to the MAX133CPL. Identical resolution (3.75 digit), sampling rate (20 per second), channel count (3), supply voltage (±5V), operating temperature range (0°C to 70°C), and 40-DIP package configuration enable direct substitution without circuit redesign or PCB modification.

Q: What is the primary difference between the MAX133CPL and MAX133CPL+?

A: The MAX133CPL is classified as obsolete with RoHS non-compliant status. The MAX133CPL+ is an active product with ROHS3 compliance. Both components are functionally equivalent and share identical electrical and mechanical specifications.

Q: Are there any packaging differences between these parts?

A: Both parts use the 40-DIP (0.600", 15.24mm) through-hole package. The MAX133CPL+ is supplied in tube packaging, while the MAX133CPL uses standard packaging. This distinction affects only handling and storage logistics, not electrical or mechanical compatibility.

Q: Is the MAX133CPL+ suitable for applications requiring RoHS compliance?

A: Yes. The MAX133CPL+ is ROHS3 compliant, making it suitable for applications and procurement environments with RoHS requirements. The original MAX133CPL is RoHS non-compliant.

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

A: Both the MAX133CPL and MAX133CPL+ have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts subject to REACH regulations?

A: No. Both the MAX133CPL and MAX133CPL+ have REACH Unaffected status, meaning REACH regulations do not apply to these components.
