DSC1001AI2-001.0000 Equivalent & Substitute Parts

Part Overview

The DSC1001AI2-001.0000 is a 1 MHz MEMS-based XO (Standard) oscillator manufactured by Microchip Technology. This CMOS oscillator operates across a 1.8V to 3.3V supply range and features standby (power down) functionality. The device is housed in a 4-VDFN Exposed Pad surface mount package with dimensions of 7.00mm x 5.00mm and a maximum seated height of 0.90mm. The part maintains an active product status and carries AEC-Q100 automotive-grade qualification. Equivalent substitute parts are identified when they maintain identical electrical performance specifications and mechanical compatibility within the same package footprint.

Substitute Part Grouping Explanation

Substitute parts for the DSC1001AI2-001.0000 are identified based on strict equivalence across the following critical parameters:

• Frequency: 1 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Voltage Supply Range: 1.8V ~ 3.3V (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Type: 4-VDFN Exposed Pad (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• Maximum Height: 0.90mm (exact match required)
• Base Resonator: MEMS (exact match required)
• Function: Standby (Power Down) (exact match required)
• AEC-Q100 Qualification: Required for automotive applications

The DSC1004AI2-001.0000 meets all substitution criteria as a parametric equivalent within this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the DSC1001AI2-001.0000 and DSC1004AI2-001.0000 are active products from Microchip Technology with identical electrical and mechanical specifications. The DSC1004AI2-001.0000 offers improved moisture sensitivity characteristics (MSL 1 versus MSL 3), which may provide advantages in storage and handling environments with extended shelf life requirements. Both parts maintain AEC-Q100 automotive-grade qualification and ROHS3 compliance. Selection between these parts should be based on inventory availability, lead time requirements, and specific moisture sensitivity level requirements for the application.

Frequently Asked Questions (FAQ)

Q: Can the DSC1004AI2-001.0000 directly replace the DSC1001AI2-001.0000 in existing designs?

A: Yes. Both parts share identical frequency, output type, voltage supply range, frequency stability, operating temperature range, package type, and package dimensions. The maximum supply current difference (6.5mA versus 6.3mA) is within acceptable design margins for CMOS oscillator applications.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: The DSC1001AI2-001.0000 has MSL 3 (168 hours), while the DSC1004AI2-001.0000 has MSL 1 (unlimited). MSL 1 indicates superior moisture resistance and allows for extended storage periods without requiring baking procedures prior to reflow soldering. This difference does not affect electrical performance but impacts handling and storage protocols.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the DSC1001AI2-001.0000 and DSC1004AI2-001.0000 carry AEC-Q100 automotive-grade qualification, making them suitable for automotive-grade circuit designs.

Q: Do these parts require different PCB footprints?

A: No. Both parts use the 4-VDFN Exposed Pad package with identical dimensions (7.00mm x 5.00mm) and maximum height (0.90mm). PCB footprints are interchangeable.

Q: What is the difference between the DSC1001 and DSC1004 series designations?

A: The series designation reflects the internal product line classification within Microchip Technology's oscillator portfolio. From an electrical and mechanical standpoint, these parts are parametric equivalents for the specified frequency and package configuration.
