MAX4515CSA Equivalent & Substitute Parts
Part Overview
The MAX4515CSA is a single-circuit SPST (Single Pole Single Throw) normally-closed analog switch manufactured by Analog Devices Inc./Maxim Integrated. This interface component operates with a single supply voltage range of 2V to 12V and features a maximum on-state resistance of 20Ohm with fast switching characteristics (150ns turn-on, 100ns turn-off). The device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning.

Substitute Part Grouping Explanation
Substitution eligibility for the MAX4515CSA is determined by strict equivalence across the following critical parameters:
- Switch circuit topology (SPST - NC configuration)
- Single-circuit, 1:1 multiplexer/demultiplexer architecture
- On-state resistance specification (20Ohm maximum)
- Supply voltage compatibility (2V ~ 12V single supply)
- Switching speed performance (150ns turn-on, 100ns turn-off)
- Charge injection and capacitance characteristics (2pC, 14pF)
- Leakage current specification (1nA maximum)
- Package form factor (8-SOIC surface mount)
- Operating temperature range (0°C ~ 70°C)
The MAX4515CSA+ meets all substitution criteria and is classified as a direct equivalent based on identical electrical specifications and mechanical compatibility.

Engineering Selection Recommendations
The MAX4515CSA+ is a direct functional equivalent to the MAX4515CSA. Both parts share identical electrical specifications, switching characteristics, and mechanical packaging. The primary distinction is RoHS compliance status: the MAX4515CSA is RoHS non-compliant, while the MAX4515CSA+ is ROHS3 compliant. For applications subject to RoHS regulatory requirements, the MAX4515CSA+ is the appropriate selection. Both parts maintain REACH unaffected status and EAR99 export classification. Moisture sensitivity level (MSL 1 - Unlimited) is identical across both variants, indicating no special handling requirements during storage or assembly.
Frequently Asked Questions (FAQ)
Q: Can MAX4515CSA+ be used as a direct replacement for MAX4515CSA in existing designs?
A: Yes. The MAX4515CSA+ is electrically and mechanically identical to the MAX4515CSA. Both parts feature the same 8-SOIC package, identical pin configuration, and equivalent electrical performance across all specified parameters. No design modifications are required for substitution.
Q: What is the difference between MAX4515CSA and MAX4515CSA+?
A: The primary difference is RoHS compliance. The MAX4515CSA is RoHS non-compliant, while the MAX4515CSA+ is ROHS3 compliant. All electrical specifications, switching characteristics, and package dimensions are identical.
Q: Are there any temperature or voltage derating considerations when substituting these parts?
A: No. Both parts operate identically across the specified temperature range (0°C ~ 70°C) and supply voltage range (2V ~ 12V). Operating conditions remain unchanged between the two variants.
Q: What packaging options are available for these parts?
A: Both the MAX4515CSA and MAX4515CSA+ are supplied in 8-SOIC surface mount packages with identical dimensions (0.154" width, 3.90mm). The MAX4515CSA+ is available in Tube packaging, while the MAX4515CSA packaging specification is not detailed in the provided data.
Q: Are there any lead-time or availability differences between these substitutes?
A: Availability varies by supplier and time. Current inventory levels differ: MAX4515CSA has 3900 pieces in stock, while MAX4515CSA+ has 1183 pieces in stock. Procurement decisions should account for current inventory status and project timelines.
