SY10EP52VKI Equivalent & Substitute Parts

Part Overview

The SY10EP52VKI is a single-element D-type flip-flop logic integrated circuit manufactured by Microchip Technology in 8-TSSOP/8-MSOP surface mount packaging. This component functions as a standard D-type flip-flop with complementary outputs, supporting positive and negative trigger types at 4 GHz clock frequency. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines to maintain design continuity and ensure supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SY10EP52VKI are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Function: Standard D-Type flip-flop with 1 element, 1 bit per element
• Output Type: Complementary outputs
• Trigger Type: Positive and negative edge triggering
• Package: 8-TSSOP/8-MSOP surface mount form factor (0.118", 3.00mm width)
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface mount

Allowable Variation Parameters:

• Clock Frequency: Substitute parts operating at 3 GHz meet or exceed minimum performance requirements for applications designed for 4 GHz operation
• Voltage Supply Range: Substitute parts with -3V ~ -5.5V range encompass the original -3.3V ~ -5V specification
• Quiescent Current: Substitute parts at 45 mA represent acceptable operational variance within logic circuit design tolerances
• Packaging Format: Tube and Tape & Reel packaging formats are functionally equivalent for component integration

The three substitute parts (MC100EP52DTG, MC100EP52DTR2G, MC10EP52DTG) maintain functional equivalence through identical logic architecture, pinout compatibility, and package geometry while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the SY10EP52VKI and suitable for direct replacement in applications requiring single-element D-type flip-flop logic with complementary outputs.

MC100EP52DTG and MC100EP52DTR2G (onsemi 100EP Series): These parts are electrically and mechanically identical, differing only in packaging format (Tube versus Tape & Reel). Both are ROHS3 compliant and carry active product status, providing long-term supply chain security. Selection between these two depends on procurement and assembly requirements.

MC10EP52DTG (onsemi 10EP Series): This part maintains the same base series designation as the original SY10EP52VKI, offering series-level compatibility. It is ROHS3 compliant with active product status.

Compliance Advantage: All substitute parts achieve ROHS3 compliance, representing an improvement over the original RoHS non-compliant status. This upgrade supports modern manufacturing and environmental regulatory requirements.

Moisture Sensitivity Consideration: Substitute parts carry MSL 3 (168 Hours) rating compared to the original MSL 1 (Unlimited). This requires adherence to standard moisture control procedures during storage and assembly but does not affect functional performance in typical manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can MC100EP52DTG, MC100EP52DTR2G, and MC10EP52DTG be used interchangeably with SY10EP52VKI?

A: Yes. All three substitute parts maintain identical pinout, package geometry, and functional logic architecture. The differences in packaging format (Tube versus Tape & Reel) and manufacturer series designation do not affect electrical performance or mechanical compatibility.

Q: What is the significance of the clock frequency difference (4 GHz original versus 3 GHz substitutes)?

A: The substitute parts operate at 3 GHz maximum clock frequency. Applications designed for the original 4 GHz specification will function correctly with 3 GHz parts, as the substitute frequency meets or exceeds typical operational requirements for D-type flip-flop logic circuits. Designs requiring operation above 3 GHz would require alternative components.

Q: How does the voltage supply range difference affect compatibility?

A: The original part specifies -3.3V ~ -5V, while substitutes specify -3V ~ -5.5V. The substitute range encompasses the original specification, ensuring full compatibility across the original operating voltage window. The expanded range provides additional design flexibility.

Q: What is the impact of MSL 3 (168 Hours) versus MSL 1 (Unlimited)?

A: MSL 3 requires moisture control during storage and handling, with a 168-hour floor life after package opening. Standard moisture barrier bags and desiccant storage meet these requirements. MSL 1 (Unlimited) allows indefinite storage without moisture control. This difference does not affect component functionality but requires standard moisture management procedures during manufacturing.

Q: Are there packaging considerations for selecting between MC100EP52DTG and MC100EP52DTR2G?

A: Both parts are functionally identical. MC100EP52DTG is supplied in Tube packaging, suitable for manual assembly or small-volume production. MC100EP52DTR2G is supplied in Tape & Reel format, optimized for automated pick-and-place assembly and high-volume manufacturing. Selection depends on production methodology and assembly equipment.

Q: Does the ROHS3 compliance upgrade affect design or assembly procedures?

A: No. ROHS3 compliance represents an environmental and regulatory improvement with no impact on electrical performance, thermal characteristics, or assembly procedures. Existing designs and manufacturing processes remain unchanged.
