Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4545CWP is determined by strict equivalence across the following critical parameters:

• Switch circuit topology: SPST configuration
• Channel count: 4 channels
• On-state resistance: Maximum 20Ω
• Supply voltage ranges: 2.7V ~ 12V (single) and ±2.7V ~ 6V (dual)
• Bandwidth performance: 300MHz -3dB bandwidth
• Functional features: Bi-directional, T-switch configuration capability
• Package specification: 20-SOIC form factor
• Mounting technology: Surface mount

Only components meeting all these parameters qualify as direct substitutes. The substitute identified maintains identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX4545CWP+ is the direct substitute for the MAX4545CWP. Both components are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications across all critical parameters.

The MAX4545CWP+ offers two significant advantages over the main part:

1. Product Status: The MAX4545CWP+ maintains active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity.

2. Compliance: The MAX4545CWP+ is ROHS3 compliant, whereas the MAX4545CWP is RoHS non-compliant. This compliance improvement supports regulatory requirements and environmental standards for new designs and manufacturing processes.

Both components are functionally interchangeable in applications requiring quad SPST video switching with 300MHz bandwidth, 20Ω on-state resistance, and flexible supply voltage operation. The selection between these parts should be based on product availability, supply chain requirements, and compliance mandates specific to the application or manufacturing region.

Frequently Asked Questions (FAQ)

Q: Can MAX4545CWP+ be used as a direct replacement for MAX4545CWP in existing designs?

A: Yes. The MAX4545CWP+ is electrically and mechanically identical to the MAX4545CWP. All electrical parameters, including on-state resistance, bandwidth, supply voltage ranges, and channel configuration, are equivalent. The 20-SOIC package dimensions and surface mount technology are identical, enabling direct PCB-level substitution without design modification.

Q: What is the significance of the product status difference between these parts?

A: The MAX4545CWP is classified as obsolete, indicating discontinued manufacturing and limited long-term availability. The MAX4545CWP+ maintains active status, meaning the manufacturer continues production, provides technical support, and guarantees supply availability. For new designs or long-term production requirements, the active MAX4545CWP+ is the preferred selection.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both the RoHS non-compliant MAX4545CWP and ROHS3 compliant MAX4545CWP+ deliver identical electrical characteristics. The compliance difference is relevant for manufacturing processes, supply chain requirements, and regulatory adherence in specific regions or industries.

Q: Are there packaging differences between MAX4545CWP and MAX4545CWP+?

A: The MAX4545CWP+ is supplied in tube packaging, while the MAX4545CWP packaging specification is not detailed in available documentation. Both components use the same 20-SOIC package form factor. Packaging differences affect handling, storage, and ordering quantities but do not impact electrical or mechanical compatibility.

Q: What parameters must remain constant for substitution eligibility?

A: Direct substitution requires equivalence in switch circuit type (SPST), channel count (4), on-state resistance (20Ω maximum), supply voltage ranges (2.7V ~ 12V single, ±2.7V ~ 6V dual), bandwidth (300MHz -3dB), functional features (bi-directional, T-switch configuration), package form factor (20-SOIC), and mounting technology (surface mount). Deviation in any of these parameters disqualifies a component as a direct substitute.
