SY10EP52VKC Equivalent & Substitute Parts

Part Overview

The SY10EP52VKC is a single-element D-type flip-flop logic integrated circuit manufactured by Microchip Technology, housed in an 8-TSSOP/8-MSOP surface mount package. This component features complementary outputs, positive and negative trigger capability, and operates at clock frequencies up to 4 GHz. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SY10EP52VKC is determined by the following critical parameters:

Functional Compatibility: All substitute parts must be single-element D-type flip-flops with complementary outputs and positive/negative trigger capability.

Electrical Compatibility: Substitute parts must support the same logic function, trigger types, and output configuration. Supply voltage ranges and quiescent current specifications must be compatible with the original design operating conditions.

Package Compatibility: All substitutes must use the 8-TSSOP or 8-MSOP surface mount package with 0.118" (3.00mm) width to ensure PCB layout compatibility without redesign.

Pin Configuration: The physical pin arrangement must match the original part to enable direct socket replacement.

The identified substitute parts—MC100EP52DTR2G and MC10EP52DTG—meet these core substitution criteria while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

MC100EP52DTR2G (onsemi): This part is the manufacturer-recommended primary substitute. It maintains active product status with ROHS3 compliance and extended operating temperature range (-40°C to 85°C). The supply voltage range (-3V to -5.5V) encompasses the original specification. Clock frequency is rated at 3 GHz, which is lower than the original 4 GHz specification but remains suitable for applications not requiring the maximum frequency capability. Quiescent current is reduced to 45 mA. Packaging is supplied in Tape & Reel format with MSL 3 rating.

MC10EP52DTG (onsemi): This alternative substitute shares identical electrical specifications with MC100EP52DTR2G, including active product status, ROHS3 compliance, and extended temperature range. The primary distinction is packaging format, supplied in Tube configuration rather than Tape & Reel. This part is appropriate for applications where tube packaging is acceptable or preferred.

Both substitutes provide improved compliance posture and extended product lifecycle compared to the discontinued original part. Selection between them depends on packaging requirements and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can MC100EP52DTR2G or MC10EP52DTG be used as direct replacements for SY10EP52VKC?

A: Yes, both parts are functionally and physically compatible. They share identical logic function, trigger types, complementary output configuration, and 8-TSSOP/8-MSOP package specifications. Pin configuration matches the original part, enabling direct socket replacement without PCB redesign.

Q: What is the significance of the clock frequency difference (4 GHz vs. 3 GHz)?

A: The original SY10EP52VKC is rated for 4 GHz maximum clock frequency, while both onsemi substitutes are rated at 3 GHz. This difference is relevant only for applications operating at clock frequencies between 3 GHz and 4 GHz. Applications operating below 3 GHz are unaffected by this specification difference.

Q: How do the supply voltage ranges compare?

A: The original part specifies -3.3V to -5V. Both substitutes specify -3V to -5.5V, which provides a wider operating range. The original specification is fully contained within the substitute range, ensuring compatibility across all original design operating points.

Q: What is the impact of the extended operating temperature range?

A: The original part operates from 0°C to 70°C. Both substitutes operate from -40°C to 85°C, providing extended temperature capability. This broader range does not create compatibility issues; designs operating within the original 0°C to 70°C window remain fully supported.

Q: What does ROHS3 compliance mean for my application?

A: ROHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive 3, restricting specified hazardous materials in electrical and electronic equipment. The original part is RoHS non-compliant. If your application or end market requires RoHS compliance, both onsemi substitutes satisfy this requirement.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Both are surface mount packaging formats. Tape & Reel (MC100EP52DTR2G) is standard for automated assembly processes. Tube (MC10EP52DTG) is suitable for manual assembly or lower-volume applications. Electrical and functional specifications are identical; packaging choice depends on assembly methodology and supply chain requirements.

Q: How does Moisture Sensitivity Level (MSL) affect component handling?

A: The original part has MSL 1 (unlimited shelf life without moisture control). Both substitutes have MSL 3 (168-hour maximum floor life after moisture exposure). MSL 3 components require moisture control during storage and handling but are standard in modern manufacturing. Proper moisture management procedures must be implemented during component storage and assembly.
