SY100EL16VCKI Equivalent & Substitute Parts

Part Overview

The SY100EL16VCKI 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, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates across -40°C to 85°C and supports both 3.3V and 5V supply voltages, making it suitable for mixed-voltage differential signaling applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SY100EL16VCKI are qualified based on the following electrical and mechanical parameters:

Core Compatibility Criteria:

• Logic Type: Differential Receiver
• Number of Bits: 1
• Package / Case: 8-TSSOP or 8-MSOP (0.118", 3.00mm Width)
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount

Voltage Supply Compatibility: Substitutes are grouped into two categories based on supply voltage specifications:

• Dual-voltage parts (3.3V and 5V): Direct functional equivalents
• Single-voltage parts (3.3V only or 5V only): Conditional substitutes depending on application requirements

The SY100EL16VCKI accepts both 3.3V and 5V supplies. Substitutes with narrower voltage ranges (3V–3.8V or 4.2V–5.7V) are valid only when the application operates within those specified ranges.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Recommended for Direct Replacement): SY100EL16VCKG is the optimal substitute. It is manufactured by the same supplier (Microchip Technology), maintains identical dual-voltage supply capability (3.3V, 5V), and operates across the same temperature range. The primary difference is RoHS3 compliance and active product status, making it suitable for new designs and ongoing production.

Secondary Substitutes (Conditional Selection):

• MC100EL16DTR2G: Valid for applications operating at 5V supply only (4.2V–5.7V range). Manufactured by onsemi with ROHS3 compliance and active status.
• MC100LVEL16DTG and MC100LVEL16DTR2G: Valid for applications operating at 3.3V supply only (3V–3.8V range). Both are onsemi products with ROHS3 compliance and active status. MC100LVEL16DTR2G offers higher inventory availability (8990 Pcs).

Compliance Consideration: All substitute parts are ROHS3 compliant, whereas the original SY100EL16VCKI is RoHS non-compliant. This is advantageous for new designs subject to RoHS regulations.

Frequently Asked Questions (FAQ)

Q: Can SY100EL16VCKG be used as a direct replacement for SY100EL16VCKI? A: Yes. Both parts are manufactured by Microchip Technology, support 3.3V and 5V supplies, use the same 8-MSOP package, and operate across -40°C to 85°C. The primary difference is packaging format (Tube vs. Bulk) and RoHS compliance status.

Q: What is the difference between MC100EL16DTR2G and MC100LVEL16DTR2G? A: MC100EL16DTR2G operates at 4.2V–5.7V (5V-centric), while MC100LVEL16DTR2G operates at 3V–3.8V (3.3V-centric). Both use 8-TSSOP packages and are suitable for their respective voltage domains. Selection depends on the application's supply voltage requirement.

Q: Are the onsemi parts (MC100 series) pin-compatible with the Microchip SY100EL16 series? A: Yes. All substitute parts use 8-TSSOP or 8-MSOP packages with 0.118" (3.00mm) width, ensuring mechanical and electrical pin compatibility for differential receiver functionality.

Q: Does packaging type (Bulk, Tube, Tape & Reel) affect electrical performance? A: No. Packaging type affects only procurement, handling, and storage logistics. Electrical performance and specifications remain identical across all packaging formats for the same part number.

Q: Which substitute should be selected for a new design? A: SY100EL16VCKG is recommended for designs requiring dual-voltage support (3.3V and 5V). For single-voltage applications, MC100LVEL16DTR2G (3.3V) or MC100EL16DTR2G (5V) are appropriate, with the added benefit of higher inventory availability in the case of MC100LVEL16DTR2G.
