SY100EL16VAZC TR Equivalent & Substitute Parts

Part Overview

The SY100EL16VAZC TR is a differential receiver IC manufactured by Microchip Technology, designed for 5V/3.3V logic applications in an 8-SOIC surface mount package. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The 100EL series differential receiver provides single-bit reception capability across industrial temperature ranges, supporting both 3.3V and 5V supply voltage domains.

Substitute Part Grouping Explanation

Substitution for the SY100EL16VAZC TR is determined by the following critical parameters:

Electrical Compatibility: Supply voltage range, logic type (differential receiver), and number of bits (1-bit) must match or be compatible with the original specification.

Mechanical Compatibility: Package type (8-SOIC) and mounting method (surface mount) must be identical to ensure PCB layout compatibility without redesign.

Thermal Compatibility: Operating temperature range (-40°C ~ 85°C) must be maintained or exceeded.

Functional Equivalence: All substitute parts must perform single-bit differential reception with identical pin configuration and signal characteristics.

The substitute parts are grouped into two voltage families:

5V Family (4.2V ~ 5.7V supply): MC100EL16DG, MC100EL16DR2G, and SN65EL16D provide direct functional equivalence for 5V applications.

3.3V Family (3V ~ 3.8V supply): MC100LVEL16DG and MC100LVEL16DR2G are optimized for 3.3V logic domains.

Engineering Selection Recommendations

For 5V Applications: MC100EL16DR2G is the primary substitute, offering active product status, ROHS3 compliance, and tape & reel packaging matching the original format. MC100EL16DG provides equivalent electrical performance with tube packaging. SN65EL16D from Texas Instruments offers an alternative from a different manufacturer with identical voltage specifications.

For 3.3V Applications: MC100LVEL16DR2G is recommended for tape & reel requirements, while MC100LVEL16DG serves tube packaging needs. Both maintain active product status and ROHS3 compliance.

Compliance Upgrade: All substitute parts are ROHS3 compliant, addressing the RoHS non-compliance status of the original SY100EL16VAZC TR. This upgrade is beneficial for new designs and regulatory requirements.

Inventory Availability: MC100EL16DR2G offers the highest inventory level (17,117 pcs), ensuring supply chain continuity for production volumes.

Frequently Asked Questions (FAQ)

Q: Can MC100EL16DG replace SY100EL16VAZC TR directly?

A: Yes, for 5V applications. Both parts share identical 8-SOIC packaging, -40°C ~ 85°C operating temperature, and single-bit differential receiver functionality. The primary difference is packaging format (tube vs. tape & reel) and manufacturer.

Q: What is the difference between MC100EL16DR2G and MC100LVEL16DR2G?

A: Supply voltage range differs. MC100EL16DR2G operates at 4.2V ~ 5.7V (5V family), while MC100LVEL16DR2G operates at 3V ~ 3.8V (3.3V family). Select based on your circuit's supply voltage domain.

Q: Is SN65EL16D compatible with the original part?

A: Yes, for 5V applications. SN65EL16D provides equivalent 5V supply voltage range (4.2V ~ 5.7V), identical 8-SOIC package, and matching operating temperature. It is manufactured by Texas Instruments rather than onsemi.

Q: Does packaging format (tube vs. tape & reel) affect electrical performance?

A: No. Tube and tape & reel packaging formats contain identical die and electrical characteristics. Selection depends on assembly process requirements and inventory handling procedures.

Q: Are all substitute parts RoHS compliant?

A: Yes. All five substitute parts are ROHS3 compliant, unlike the original SY100EL16VAZC TR which is RoHS non-compliant. This represents a compliance improvement for new designs.

Q: Can I use a 3.3V part (MC100LVEL16DR2G) in a 5V circuit?

A: No. MC100LVEL16DR2G is specified for 3V ~ 3.8V supply voltage and will not operate correctly at 5V. Use MC100EL16DR2G or MC100EL16DG for 5V applications.

Q: What is the pin compatibility between substitute parts?

A: All substitute parts maintain identical 8-SOIC pin configuration and signal characteristics, ensuring direct PCB compatibility without layout modifications.
