MAX664CSA-T Equivalent & Substitute Parts

Part Overview

The MAX664CSA-T is a linear voltage regulator IC from Analog Devices Inc./Maxim Integrated designed for negative adjustable output applications. This Surface Mount device delivers 40mA output current in an 8-SOIC package and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for design continuity and procurement planning. The substitute identified maintains identical electrical specifications and mechanical compatibility while offering active product status.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX664CSA-T is determined by strict equivalence across the following critical parameters:

• Output Configuration: Negative
• Output Type: Adjustable (Fixed)
• Current - Output: 40mA
• Voltage - Input (Max): -16.5V
• Voltage - Output Range: -1.3V to -16V
• Voltage Dropout: 0.35V @ 40mA
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Control Features: Current Limit, Enable
• Operating Temperature: 0°C ~ 70°C

The identified substitute part maintains identical electrical performance and mechanical compatibility. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The MAX664CSA+T is a direct functional equivalent to the MAX664CSA-T. Both parts share identical electrical specifications, thermal characteristics, and mechanical form factor. The MAX664CSA+T carries Active product status from Analog Devices Inc./Maxim Integrated, ensuring continued availability and manufacturing support. Both variants maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current applications.

The substitution is valid for all applications where the MAX664CSA-T was originally specified. The difference in packaging format (Tube versus Tape & Reel) does not affect electrical performance or PCB-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX664CSA+T replace MAX664CSA-T in existing designs? A: Yes. Both parts are electrically and mechanically identical. The MAX664CSA+T is the active equivalent with identical pin configuration, electrical performance, and package dimensions.

Q: What is the difference between the two part numbers? A: The primary difference is packaging format. MAX664CSA-T uses Tube packaging, while MAX664CSA+T uses Tape & Reel (TR) packaging. The "+T" suffix indicates Tape & Reel format. Electrical specifications and die characteristics are identical.

Q: Are there any compliance or certification differences? A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical Moisture Sensitivity Level (MSL) ratings. Regulatory compliance is equivalent.

Q: Is the 8-SOIC package footprint identical? A: Yes. Both parts use the same 8-SOIC package with 0.154" width (3.90mm). PCB layout and reflow profiles remain unchanged.

Q: Why is MAX664CSA-T marked as obsolete? A: Obsolete status indicates the part is no longer in active production. The MAX664CSA+T remains in active production and serves as the current equivalent for new designs and replacements.

Q: Can I mix packaging formats in the same production run? A: Packaging format does not affect electrical performance or compatibility. However, supply chain and handling procedures may differ between Tube and Tape & Reel formats. Verify with your procurement and assembly processes.
