Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS853011CGLF is determined by the following critical parameters that must be maintained or exceeded:

• Ratio - Input:Output: Must be 1:2 (one input, two outputs)
• Differential Configuration: Both input and output must be differential
• Frequency - Max: Must support at least 2.5 GHz operation
• Voltage - Supply: Must operate within 2.375V ~ 3.8V range
• Operating Temperature: Must support -40°C ~ 85°C range
• Package / Case: Must be 8-TSSOP form factor for PCB compatibility
• Mounting Type: Must be Surface Mount

The substitute parts identified (MC100LVEP11DTG, MC100LVEP11DTR2G, and MC10LVEP11DTG) all meet or exceed these parameters. These onsemi components are active products with enhanced frequency capability (3 GHz maximum), ensuring forward compatibility while maintaining electrical and mechanical compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (MC100LVEP11DTG, MC100LVEP11DTR2G, and MC10LVEP11DTG) are active products from onsemi with ROHS3 compliance, providing long-term availability and regulatory alignment superior to the obsolete ICS853011CGLF.

MC100LVEP11DTR2G is recommended as the primary substitute due to highest inventory availability (4272 pieces) and Tape & Reel packaging, which is standard for production environments. This part maintains full electrical compatibility while offering enhanced frequency performance at 3 GHz.

MC100LVEP11DTG and MC10LVEP11DTG are functionally equivalent alternatives, available in Tube packaging with comparable inventory levels (1417 and 1127 pieces respectively). Selection between these variants depends on packaging requirements and supply chain preferences.

All substitute parts maintain identical supply voltage range, operating temperature range, and MSL rating as the original component, ensuring direct compatibility in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can MC100LVEP11DTG directly replace ICS853011CGLF on existing PCBs?

A: Yes. Both parts use 8-TSSOP surface mount packaging with identical electrical specifications for supply voltage (2.375V ~ 3.8V), operating temperature (-40°C ~ 85°C), and MSL rating (3). The 1:2 differential input/output configuration and signal standards are compatible. The substitute offers higher frequency capability (3 GHz vs. 2.5 GHz), which does not create compatibility issues in existing designs.

Q: What is the difference between MC100LVEP11DTG and MC100LVEP11DTR2G?

A: These parts are electrically identical. The primary difference is packaging format: MC100LVEP11DTG is supplied in Tube packaging, while MC100LVEP11DTR2G is supplied in Tape & Reel (TR) format. Tape & Reel packaging is preferred for automated assembly and high-volume production. Both maintain identical electrical performance and compliance certifications.

Q: Are the onsemi substitutes RoHS compliant?

A: Yes. All three onsemi substitute parts (MC100LVEP11DTG, MC100LVEP11DTR2G, and MC10LVEP11DTG) are ROHS3 compliant, whereas the original ICS853011CGLF RoHS status is not specified. This provides regulatory advantage for new designs and production.

Q: Does the higher 3 GHz frequency rating of substitute parts affect circuit design?

A: No. The substitute parts operate at the same maximum supply voltage, temperature range, and MSL rating as the original. The higher frequency rating (3 GHz vs. 2.5 GHz) represents enhanced capability and does not require design modifications. Existing circuits designed for 2.5 GHz operation remain fully compatible.

Q: What is the significance of the different package dimensions noted for substitute parts?

A: The substitute parts are specified as 8-TSSOP with two possible width dimensions: 0.173" (4.40mm) or 0.118" (3.00mm). The original ICS853011CGLF specifies 0.173" (4.40mm) width. Verify PCB footprint compatibility with your design documentation before procurement. Contact the supplier if clarification on physical dimensions is required for your specific application.
