SY10E016JC 8-Bit Binary Counter Equivalent & Substitute Parts

Part Overview

The SY10E016JC is an 8-bit binary counter logic IC manufactured by Microchip Technology, housed in a 28-PLCC surface mount package. This component functions as a synchronous counter with asynchronous reset, capable of counting at rates up to 900 MHz with positive and negative trigger capability. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers to maintain design continuity and procurement availability.

Substitute Part Grouping Explanation

Substitution eligibility for the SY10E016JC is determined by functional and electrical parameter alignment across the following criteria:

Core Functional Parameters (Must Match):

Logic Type: Binary Counter
Bit Configuration: 8-bit, single element
Count Direction: Up
Reset Architecture: Asynchronous
Timing Mode: Synchronous
Count Rate: 900 MHz minimum
Trigger Capability: Positive and Negative

Electrical Compatibility Parameters:

Supply Voltage Range: Must encompass or overlap with 4.2 V ~ 5.5 V
Operating Temperature: Must support at least 0°C ~ 85°C range

Physical Compatibility Parameters:

Engineering Selection Recommendations

Both MC10E016FNG and MC10E016FNR2G provide direct functional substitution for the SY10E016JC with the following considerations:

Voltage Supply Range: The onsemi alternatives extend the upper supply voltage limit to 5.7 V, providing broader operational margin compared to the original 5.5 V specification. Both parts maintain the 4.2 V lower threshold, ensuring compatibility with existing power supply designs.

Operating Temperature: The substitute parts operate from 0°C to 85°C, compared to the original -40°C to 85°C range. Applications requiring operation below 0°C cannot use these substitutes without thermal management verification.

Regulatory Compliance: Both onsemi parts are ROHS3 compliant, whereas the original SY10E016JC is non-compliant. This compliance status is relevant for applications subject to RoHS directives in target markets.

Packaging Availability: MC10E016FNG is supplied in Tube packaging with 36,200 units in stock. MC10E016FNR2G is supplied in Cut Tape format with 1,755 units in stock. Selection between these variants depends on assembly process requirements and procurement volume.

Frequently Asked Questions (FAQ)

Q: Can MC10E016FNG and MC10E016FNR2G be used interchangeably with SY10E016JC?

A: Yes, both onsemi parts are functionally equivalent. The primary differences are packaging format (Tube vs. Cut Tape) and inventory levels. Pin configuration and electrical performance are identical.

Q: What is the difference between MC10E016FNG and MC10E016FNR2G?

A: Both parts are electrically and functionally identical. The difference is packaging: MC10E016FNG uses Tube packaging while MC10E016FNR2G uses Cut Tape. Selection depends on assembly line requirements and order quantity.

Q: Are there temperature range limitations when substituting?

A: Yes. The onsemi substitutes operate from 0°C to 85°C, whereas the original operates from -40°C to 85°C. If your application requires operation below 0°C, these substitutes are not suitable without additional thermal management.

Q: Does the extended voltage range of the substitutes affect circuit design?

A: No. The substitutes support 4.2 V ~ 5.7 V, which encompasses the original 4.2 V ~ 5.5 V range. Existing designs operating within the original voltage specification will function without modification.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both MC10E016FNG and MC10E016FNR2G are ROHS3 compliant, whereas the original SY10E016JC is non-compliant. This is relevant for applications subject to RoHS regulations.

Q: What is the pin compatibility between these parts?

A: All three parts use the 28-LCC (J-Lead) package with identical pin configuration. Direct PCB footprint compatibility is confirmed.
