MAX253CSA Equivalent & Substitute Parts

Part Overview

The MAX253CSA is a Transformer Driver PMIC manufactured by Analog Devices Inc./Maxim Integrated, designed for RS485 applications in 8-SOIC surface mount packaging. This component is classified as obsolete, with 1105 units currently available in new original stock. Due to its obsolete status, identifying compatible substitute parts is essential for ongoing system support and new design implementations. The MAX253CSA+ serves as the direct active equivalent, offering identical electrical and mechanical specifications with improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX253CSA is determined by strict equivalence across the following critical parameters:

• Electrical specifications: Current supply (450µA), voltage supply range (3.3V, 5V), and operating temperature range (0°C ~ 70°C)
• Mechanical compatibility: Package type (8-SOIC), case dimensions (0.154", 3.90mm Width), and surface mount mounting type
• Functional classification: Transformer Driver PMIC for RS485 applications
• Base product designation: MAX253 series

The MAX253CSA+ meets all substitution criteria, maintaining identical electrical and mechanical parameters while offering active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The MAX253CSA+ is the direct substitute for the MAX253CSA. Both components share identical electrical specifications (450µA supply current, 3.3V/5V supply voltage, 0°C ~ 70°C operating range) and mechanical compatibility (8-SOIC package, surface mount configuration). The primary distinction is product lifecycle status: the MAX253CSA is obsolete, while the MAX253CSA+ maintains active production status. Additionally, the MAX253CSA+ achieves ROHS3 compliance, whereas the original MAX253CSA is RoHS non-compliant. For new designs and ongoing system support, the MAX253CSA+ is the appropriate selection. Both components maintain REACH Unaffected status and identical ECCN/HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can MAX253CSA+ be used as a direct replacement for MAX253CSA?

A: Yes. The MAX253CSA+ is electrically and mechanically identical to the MAX253CSA. Both components operate at 450µA supply current, support 3.3V and 5V supply voltages, function across 0°C to 70°C, and use identical 8-SOIC surface mount packaging. The primary difference is product status: MAX253CSA+ is active production while MAX253CSA is obsolete.

Q: What is the packaging difference between these parts?

A: The MAX253CSA is supplied in standard packaging, while the MAX253CSA+ is supplied in Tube packaging. Both use the same 8-SOIC (0.154", 3.90mm Width) case. Packaging format does not affect electrical or mechanical compatibility.

Q: Are there compliance differences between MAX253CSA and MAX253CSA+?

A: Yes. The MAX253CSA+ is ROHS3 compliant, while the MAX253CSA is RoHS non-compliant. Both maintain REACH Unaffected status. For applications requiring RoHS compliance, the MAX253CSA+ is the required selection.

Q: What inventory status should I consider?

A: The MAX253CSA has 1105 units in new original stock (obsolete status). The MAX253CSA+ has 2200 units in new original stock (active status). For long-term availability and supply chain stability, the MAX253CSA+ is the preferred choice.

Q: Are there any electrical parameter differences?

A: No. Both components maintain identical electrical specifications: 450µA supply current, 3.3V/5V supply voltage range, and 0°C ~ 70°C operating temperature. Substitution is direct with no circuit modifications required.
