DSC1001CC2-100.0000 MEMS Oscillator Equivalent & Substitute Parts

Part Overview

The DSC1001CC2-100.0000 is a 100 MHz MEMS-based XO (Standard) oscillator manufactured by Microchip Technology. This component operates across a 1.8V to 3.3V supply range with CMOS output, designed for applications requiring stable frequency generation with low power consumption. The part is currently in active production status with AEC-Q100 automotive-grade ratings and ROHS3 compliance. Substitute parts may be required due to inventory constraints, supply chain considerations, or specific application requirements within the allowed electrical and mechanical parameter ranges.

Substitute Part Grouping Explanation

Substitution eligibility for the DSC1001CC2-100.0000 is determined by strict alignment with the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Voltage Supply Range: 1.8V ~ 3.3V (exact match required)
• Base Resonator: MEMS (exact match required)
• Oscillator Type: XO (Standard) (exact match required)
• Function: Standby (Power Down) capability (exact match required)
• Package Footprint: 4-pin surface mount with 3.20mm x 2.50mm dimensions (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The ASEMB-100.000MHZ-LY-T from Abracon LLC meets all mandatory substitution criteria. While this substitute exhibits different frequency stability (±10ppm versus ±25ppm), extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), and higher maximum supply current (16mA versus 8.7mA), these parameters remain within acceptable tolerance for component interchangeability in the specified application category.

Parameter Comparison

Engineering Selection Recommendations

Both the DSC1001CC2-100.0000 and ASEMB-100.000MHZ-LY-T are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on the following factors:

DSC1001CC2-100.0000 is the primary choice when AEC-Q100 automotive-grade certification is a mandatory requirement, as this rating is explicitly specified for the Microchip part.

ASEMB-100.000MHZ-LY-T is suitable as a substitute when extended operating temperature range (-40°C ~ 85°C) is required beyond the primary part's 0°C ~ 70°C specification, or when improved frequency stability (±10ppm) is beneficial to system performance. This part is available in higher inventory quantities.

Both components share identical footprint dimensions, supply voltage range, frequency output, and disable current specifications, ensuring direct PCB-level compatibility when thermal and frequency stability requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can the ASEMB-100.000MHZ-LY-T replace the DSC1001CC2-100.0000 in all applications?

A: Direct substitution is valid when the application does not mandate AEC-Q100 automotive certification. The substitute part meets all electrical and mechanical compatibility requirements, including frequency, output type, supply voltage, package footprint, and compliance standards.

Q: What is the difference between 4-VDFN and 4-SMD, No Lead packaging?

A: Both designations refer to 4-pin surface mount packages with identical footprint dimensions (3.20mm x 2.50mm) and height (0.90mm maximum). The terminology reflects different manufacturer naming conventions for the same physical package form factor.

Q: Does the higher frequency stability of the ASEMB part affect circuit design?

A: The ASEMB-100.000MHZ-LY-T provides ±10ppm stability compared to the DSC1001CC2-100.0000's ±25ppm. This represents improved performance and does not require circuit redesign. Applications designed for ±25ppm tolerance will operate within specification with the substitute part.

Q: Are there thermal considerations when selecting between these parts?

A: The ASEMB-100.000MHZ-LY-T operates across -40°C ~ 85°C, while the DSC1001CC2-100.0000 operates across 0°C ~ 70°C. For applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C, the Abracon part is the appropriate selection.

Q: What is the impact of the 16mA maximum supply current on the ASEMB part versus 8.7mA on the Microchip part?

A: The ASEMB part's higher maximum supply current specification indicates worst-case power consumption. Actual operating current may be lower. Circuit power budgets should accommodate the higher specification to ensure system reliability.

Q: Are both parts available in the same packaging formats?

A: The DSC1001CC2-100.0000 is specified in standard packaging. The ASEMB-100.000MHZ-LY-T is available in Cut Tape (CT) and Digi-Reel formats, as well as Tape & Reel (TR). Verify packaging availability with your supplier for procurement requirements.
