SY10E131JC Equivalent & Substitute Parts

Part Overview

The SY10E131JC is a D-Type flip flop logic integrated circuit manufactured by Microchip Technology, featuring 1 element with 4-bit configuration and complementary output. This component operates as a single 4-bit positive edge-triggered flip flop in a 28-LCC (J-Lead) surface mount package. The part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SY10E131JC is determined by the following critical parameters that must remain consistent:

• D-Type flip flop configuration with 1 element and 4-bit structure
• Complementary output type
• Positive edge trigger mechanism
• 1.4 GHz clock frequency capability
• 28-LCC (J-Lead) surface mount package
• 70 mA quiescent current
• Voltage supply range compatibility
• Set(Preset) and Reset function

The substitute parts listed below maintain these core electrical and mechanical specifications, enabling direct functional replacement in applications designed for the SY10E131JC.

Parameter Comparison

Engineering Selection Recommendations

All three onsemi substitute parts (MC100E131FNG, MC10E131FNG, MC10E131FNR2G) maintain functional equivalence to the SY10E131JC across core electrical specifications. Selection between substitutes depends on specific application requirements:

MC100E131FNG and MC10E131FNG operate within the negative voltage supply range (-4.2V ~ -5.7V), matching the original SY10E131JC polarity with extended upper voltage tolerance. Both achieve ROHS3 compliance and support the full 0°C ~ 85°C operating temperature range, exceeding the original part's 70°C maximum.

MC10E131FNR2G operates within positive voltage supply range (4.2V ~ 5.7V), requiring circuit polarity verification before selection. This part also achieves ROHS3 compliance and 0°C ~ 85°C operating temperature range.

All substitute parts are classified as obsolete, indicating limited future availability. Procurement decisions should account for current inventory levels and long-term supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can MC100E131FNG, MC10E131FNG, and MC10E131FNR2G be used interchangeably with SY10E131JC?

A: MC100E131FNG and MC10E131FNG are direct functional equivalents, maintaining identical voltage polarity (-4.2V ~ -5.7V) and all core electrical parameters. MC10E131FNR2G operates at positive voltage (4.2V ~ 5.7V) and requires circuit verification for compatibility. All three maintain the 28-LCC (J-Lead) package, 1.4 GHz clock frequency, 4-bit D-Type configuration, and 70 mA quiescent current.

Q: What is the primary difference between the substitute parts?

A: MC100E131FNG belongs to the 100E series, while MC10E131FNG and MC10E131FNR2G belong to the 10E series. The primary electrical difference is MC10E131FNR2G operates at positive voltage supply, whereas the other two operate at negative voltage supply. All maintain identical functional specifications for flip flop operation.

Q: Are there temperature range considerations for substitution?

A: The SY10E131JC operates at 0°C ~ 70°C. All three substitute parts extend this range to 0°C ~ 85°C, providing broader thermal operating capability. Applications limited to the original 70°C maximum remain compatible with all substitutes.

Q: What packaging considerations apply to these substitutes?

A: All substitute parts use the 28-LCC (J-Lead) surface mount package, maintaining identical footprint and pinout compatibility with the SY10E131JC. Mechanical mounting and PCB layout require no modification.

Q: How does RoHS compliance affect substitution decisions?

A: The SY10E131JC is RoHS non-compliant. All three substitute parts achieve ROHS3 compliance, meeting current environmental and regulatory standards. Applications subject to RoHS requirements benefit from substitution to compliant alternatives.
