SY100EL16VCKI-TR Equivalent & Substitute Parts

Part Overview

The SY100EL16VCKI-TR is a differential receiver IC manufactured by Microchip Technology, designed for 5V/3.3V logic applications in an 8-MSOP surface mount package. This component is discontinued at DiGi Electronics, necessitating identification of active equivalent parts that maintain functional and electrical compatibility. Substitute parts must preserve the differential receiver functionality, operating temperature range, and physical package dimensions while meeting current supply chain requirements.

Substitute Part Grouping Explanation

Substitution for the SY100EL16VCKI-TR is determined by the following critical parameters:

Functional Equivalence: All substitute parts maintain differential receiver logic type with single-bit configuration.

Package Compatibility: All substitutes use 8-TSSOP or 8-MSOP packages with identical 0.118" (3.00mm) width, ensuring mechanical and electrical pin compatibility.

Operating Temperature: All substitutes maintain the -40°C ~ 85°C operating range, preserving thermal performance specifications.

Supply Voltage Consideration: The original part supports dual voltage operation (3.3V and 5V). Substitutes are grouped into two voltage families:

MC100EL16DTR2G: 4.2V ~ 5.7V (5V operation)
MC100LVEL16DTG and MC100LVEL16DTR2G: 3V ~ 3.8V (3.3V operation)

Selection depends on the specific voltage requirement of the target application.

Engineering Selection Recommendations

For 5V Applications: MC100EL16DTR2G is the primary substitute. This part is manufactured by onsemi, maintains active product status, and operates within the 4.2V ~ 5.7V range suitable for 5V logic systems. It is supplied in Tape & Reel packaging with ROHS3 compliance and 859 units in current inventory.

For 3.3V Applications: MC100LVEL16DTR2G is the recommended substitute. This part operates within the 3V ~ 3.8V range for 3.3V logic systems, maintains active product status, and is available in Tape & Reel packaging with ROHS3 compliance. Inventory availability is 8990 units. Alternatively, MC100LVEL16DTG provides the same electrical specifications in Tube packaging with 1201 units available.

Compliance Consideration: All active substitutes are ROHS3 compliant, addressing regulatory requirements not met by the discontinued SY100EL16VCKI-TR.

Packaging Selection: Tape & Reel variants (MC100EL16DTR2G, MC100LVEL16DTR2G) are suitable for automated assembly. Tube packaging (MC100LVEL16DTG) is appropriate for manual or lower-volume applications.

Frequently Asked Questions (FAQ)

Q: Can MC100EL16DTR2G replace SY100EL16VCKI-TR in all applications?

A: MC100EL16DTR2G is functionally equivalent for 5V applications only. The supply voltage range (4.2V ~ 5.7V) is compatible with 5V logic systems. For 3.3V applications, use MC100LVEL16DTR2G or MC100LVEL16DTG instead.

Q: What is the difference between MC100LVEL16DTG and MC100LVEL16DTR2G?

A: Both parts are electrically identical differential receivers with 3.3V operation (3V ~ 3.8V supply range). The primary difference is packaging: DTG is supplied in Tube format, while DTR2G is supplied in Tape & Reel format. Select based on assembly process requirements.

Q: Are the package dimensions identical between the original and substitute parts?

A: Yes. All substitute parts use 8-TSSOP or 8-MSOP packages with 0.118" (3.00mm) width, ensuring mechanical compatibility with the original SY100EL16VCKI-TR footprint.

Q: Does the moisture sensitivity level difference affect substitution?

A: The original part has MSL 1 (unlimited moisture exposure), while substitutes have MSL 3 (168 hours). This requires adherence to standard moisture handling procedures during storage and assembly. Substitutes must be stored in dry conditions and used within the specified timeframe after opening.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (MC100EL16DTR2G, MC100LVEL16DTG, MC100LVEL16DTR2G) are ROHS3 compliant, meeting current environmental regulations.
