Substitute Part Grouping Explanation

Substitution eligibility for the MAX454CSD is determined by strict equivalence across the following critical parameters:

Electrical Performance Parameters:

• -3dB Bandwidth: 50 MHz
• Slew Rate: 300 V/µs
• Current - Supply: 25 mA
• Current - Output / Channel: 20 mA
• Voltage - Supply, Single/Dual (±): ±4.5V ~ 5.5V

Functional Parameters:

• Number of Circuits: 1
• Applications: 4:1 Multiplexer-Amplifier

Physical Parameters:

• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Compliance Parameters:

• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS: 8542.39.0001

A substitute part must match all electrical performance parameters, functional specifications, and physical package requirements. Differences in product status and RoHS compliance are noted separately and do not disqualify substitution based on technical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The MAX454CSD+ is a direct technical equivalent to the MAX454CSD across all electrical performance, functional, and physical parameters. Both parts share identical specifications for bandwidth, slew rate, supply current, output current, supply voltage range, package type, and mounting configuration.

The primary differences between these parts are product status and regulatory compliance:

Product Status: The MAX454CSD is classified as obsolete, while the MAX454CSD+ is active. Active product status indicates ongoing manufacturer support and availability.

RoHS Compliance: The MAX454CSD is RoHS non-compliant. The MAX454CSD+ is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components in many jurisdictions.

For new designs or production requiring compliance with current environmental regulations, the MAX454CSD+ is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part is technically suitable based on electrical and functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can MAX454CSD+ be used as a direct replacement for MAX454CSD in existing designs?

A: Yes. The MAX454CSD+ is electrically and functionally equivalent to the MAX454CSD. All critical parameters including bandwidth, slew rate, supply current, output current, supply voltage range, and package configuration are identical. Direct substitution is supported from a technical standpoint.

Q: What is the significance of the "+" designation in MAX454CSD+?

A: The "+" suffix indicates a product variant. In this case, the MAX454CSD+ represents an updated version of the base MAX454CSD with improved regulatory compliance (ROHS3 compliant) while maintaining identical electrical and functional specifications.

Q: Are there any package or pinout differences between MAX454CSD and MAX454CSD+?

A: No. Both parts use the identical 14-SOIC package with 0.154" (3.90mm) width. Pinout and physical dimensions are identical, enabling direct PCB-level substitution without layout modifications.

Q: Why is the MAX454CSD classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand, technology evolution, and production decisions. The MAX454CSD+ represents the active continuation of this product line with maintained specifications and improved compliance.

Q: What are the supply voltage requirements for both parts?

A: Both the MAX454CSD and MAX454CSD+ operate with a supply voltage range of ±4.5V to ±5.5V (dual supply configuration). This specification is identical across both parts.

Q: Is there an inventory difference between these parts?

A: Yes. The MAX454CSD has 3,988 pieces in stock, while the MAX454CSD+ has 914 pieces in stock. Inventory levels are subject to change and should be verified with the supplier for current availability.

Q: What applications are these parts suitable for?

A: Both parts are designed for 4:1 multiplexer-amplifier applications, specifically video amplification requiring high-speed signal processing with integrated multiplexing functionality.
