SAB82526N-V21 Equivalent & Substitute Parts

Part Overview

The SAB82526N-V21 is a specialized interface integrated circuit manufactured by Infineon Technologies, housed in a 44-LCC (J-Lead) package for surface mount applications. This component operates within a supply voltage range of 4.75V to 5.25V and features serial interface capabilities. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for system redesign, legacy product support, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SAB82526N-V21 are identified based on the following critical parameters:

• Functional Category: Interface specialized integrated circuits
• Interface Protocol: Serial communication capability
• Mounting Technology: Surface mount configuration
• Moisture Sensitivity: MSL 3 classification
• Supply Voltage Compatibility: Operating voltage ranges suitable for 5V logic environments
• Product Status: Active alternatives to obsolete component

The two identified substitutes—AD6623ASZ and TW3801-TC1-CR—meet these criteria while offering modern product status and improved compliance certifications. Both alternatives are currently in active production with substantial inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SAB82526N-V21 is classified as obsolete. Both substitute parts—AD6623ASZ and TW3801-TC1-CR—maintain active product status with manufacturers, ensuring long-term availability and continued technical support.

Compliance Advantage: Both substitutes achieve ROHS3 compliance, representing a regulatory improvement over the non-compliant original part. This compliance status is beneficial for new designs and systems subject to environmental regulations.

Certification Alignment: All three parts maintain identical REACH Unaffected status and equivalent MSL 3 moisture sensitivity ratings, ensuring consistent handling and storage requirements across the component family.

Voltage Supply Consideration: The original SAB82526N-V21 operates at 4.75V to 5.25V. The TW3801-TC1-CR operates at 1.8V and 3.3V, requiring voltage level consideration in system integration. The AD6623ASZ supply voltage is not specified in available documentation.

Package Footprint: Substitution requires PCB redesign due to package differences (44-LCC versus 128-BFQFP or 100-TQFP). This is a critical consideration for legacy system retrofitting.

Frequently Asked Questions (FAQ)

Q: Can AD6623ASZ directly replace SAB82526N-V21 without PCB modification?

A: No. The AD6623ASZ uses a 128-BFQFP package compared to the 44-LCC package of the original part. PCB layout redesign is required.

Q: What are the key differences between the two substitute parts?

A: AD6623ASZ is optimized for transmit signal processing applications with a 128-pin package. TW3801-TC1-CR is designed for security systems with MII/RMII interface support and operates at lower voltage levels (1.8V, 3.3V) compared to the original 5V specification.

Q: Are both substitutes suitable for 5V logic environments?

A: AD6623ASZ supply voltage is not specified. TW3801-TC1-CR operates at 1.8V and 3.3V, which are below the original 4.75V to 5.25V range. Voltage compatibility must be verified against specific application requirements.

Q: Do the substitute parts maintain the same moisture sensitivity handling requirements?

A: Yes. All three parts are classified as MSL 3 (168 Hours), requiring identical storage and handling procedures.

Q: Which substitute offers better regulatory compliance?

A: Both AD6623ASZ and TW3801-TC1-CR achieve ROHS3 compliance, compared to the non-compliant status of the original SAB82526N-V21. Both maintain REACH Unaffected status.

Q: What inventory considerations should guide part selection?

A: All three parts maintain substantial inventory levels (1068 to 2100 pieces). AD6623ASZ and TW3801-TC1-CR, as active products, offer superior long-term availability assurance compared to the obsolete SAB82526N-V21.
