DSC1001CL2-100.0000 Equivalent & Substitute Parts

Part Overview

The DSC1001CL2-100.0000 is a 100 MHz MEMS-based XO (Standard) oscillator manufactured by Microchip Technology. This CMOS oscillator operates across a 1.8V to 3.3V supply range and includes standby (power down) functionality. The device is housed in a 4-VDFN surface mount package with dimensions of 3.20mm x 2.50mm and a maximum seated height of 0.90mm. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified operating parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the DSC1001CL2-100.0000 is determined by strict alignment with the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage Range: 1.8V ~ 3.3V (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Base Resonator Type: MEMS (exact match required)
• Function: Standby (Power Down) capability (exact match required)
• Physical Dimensions: 3.20mm x 2.50mm footprint (exact match required)
• Maximum Seated Height: 0.90mm (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: MSL 1 (exact match required)

The ASEMB-100.000MHZ-XY-T from Abracon LLC meets all critical electrical and mechanical parameters. Variations in frequency stability, maximum supply current, and package designation (4-SMD, No Lead versus 4-VDFN) do not preclude substitution when the core functional requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both the DSC1001CL2-100.0000 and ASEMB-100.000MHZ-XY-T are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on application-specific requirements and supply chain availability.

The DSC1001CL2-100.0000 is suitable for applications where the specified frequency stability of ±25ppm and maximum supply current of 12.2mA meet design requirements. The ASEMB-100.000MHZ-XY-T offers improved frequency stability at ±10ppm, which may be advantageous in timing-sensitive applications, though it draws a higher maximum supply current of 16mA. Both parts maintain identical physical footprints and thermal operating ranges, enabling direct substitution at the board level when electrical performance parameters are compatible with system specifications.

Frequently Asked Questions (FAQ)

Q: Can the ASEMB-100.000MHZ-XY-T replace the DSC1001CL2-100.0000 in existing designs?

A: Yes. Both parts share identical frequency, output type, supply voltage range, operating temperature range, physical dimensions, and moisture sensitivity level. The footprint compatibility and electrical interface are equivalent, allowing direct substitution provided the application can accommodate the ASEMB part's maximum supply current of 16mA and improved frequency stability of ±10ppm.

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

A: Both designations refer to surface mount packages with identical external dimensions (3.20mm x 2.50mm) and maximum seated height (0.90mm). The package designation difference reflects manufacturer nomenclature; the physical and electrical interfaces are compatible for PCB assembly and reflow soldering processes.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. Moisture sensitivity level is MSL 1 for both parts, indicating unlimited shelf life under standard storage conditions.

Q: How does frequency stability affect part selection?

A: Frequency stability is application-dependent. The DSC1001CL2-100.0000 specifies ±25ppm stability, while the ASEMB-100.000MHZ-XY-T specifies ±10ppm. Applications requiring tighter frequency tolerance should select the ASEMB part. Applications where ±25ppm stability is sufficient may use either part based on availability and cost considerations.

Q: What is the impact of the different maximum supply currents?

A: The DSC1001CL2-100.0000 draws a maximum of 12.2mA, while the ASEMB-100.000MHZ-XY-T draws a maximum of 16mA. Power budget calculations must account for this difference. Applications with strict power consumption limits should verify that the higher current draw of the ASEMB part is acceptable within system specifications.
