Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX6341CSA is determined by strict equivalence across the following critical parameters:

• Reference Type: Series, Buried Zener
• Output Voltage: 4.096V (fixed)
• Output Current: 15 mA
• Tolerance: ±0.02%
• Temperature Coefficient: 1ppm/°C
• Noise Specifications: 2.4µVp-p (0.1Hz to 10Hz) and 2µVrms (10Hz to 10kHz)
• Input Voltage Range: 8V ~ 36V
• Package: 8-SOIC

Only parts meeting all these electrical and mechanical specifications are considered direct substitutes. Packaging format differences (such as Tube vs. standard packaging) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MAX6341CSA+ is a direct functional equivalent to the MAX6341CSA with identical electrical performance across all specified parameters. The primary distinction is product status: MAX6341CSA+ is Active, whereas MAX6341CSA is Obsolete.

For new designs and ongoing production, MAX6341CSA+ is the appropriate selection. It provides ROHS3 compliance, addressing regulatory requirements that the original MAX6341CSA does not meet. Both parts are manufactured by the same supplier and maintain identical electrical characteristics, ensuring seamless integration into existing circuit designs without modification.

Frequently Asked Questions (FAQ)

Q: Can MAX6341CSA+ be used as a direct replacement for MAX6341CSA in existing designs?

A: Yes. Both parts are electrically identical across all specified parameters, including output voltage, tolerance, temperature coefficient, noise characteristics, and input/output current ratings. No circuit modifications are required.

Q: What is the difference between MAX6341CSA and MAX6341CSA+?

A: The parts are functionally equivalent. MAX6341CSA+ is the Active product variant with ROHS3 compliance, while MAX6341CSA is Obsolete and RoHS non-compliant. Packaging format differs (Tube vs. standard), but this does not affect electrical performance.

Q: Are there any compatibility concerns with the 8-SOIC package?

A: No. Both parts use identical 8-SOIC packaging (0.154", 3.90mm Width) and Surface Mount mounting type. PCB layouts and footprints are interchangeable.

Q: Why is MAX6341CSA marked as Obsolete?

A: Product obsolescence reflects manufacturing lifecycle decisions by Analog Devices Inc./Maxim Integrated. MAX6341CSA+ serves as the current production equivalent and is recommended for all new applications.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitutes must match the following: 4.096V fixed output, ±0.02% tolerance, 1ppm/°C temperature coefficient, 15 mA output current, 2.4µVp-p noise (0.1Hz to 10Hz), 2µVrms noise (10Hz to 10kHz), 8V ~ 36V input range, and 8-SOIC package format.
