Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSC1101DM5-020.0000 is determined by the following critical parameters:

• Frequency: 20 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Base Resonator: MEMS (exact match required)
• Function: Standby (Power Down) capability (exact match required)
• Frequency Stability: ±10ppm (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)

The DSC1001DL5-020.0000 qualifies as a substitute part because it matches all critical electrical and functional parameters. However, differences exist in supply voltage range, operating temperature range, current consumption, package configuration, and product status. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The DSC1001DL5-020.0000 is the primary substitute for the obsolete DSC1101DM5-020.0000. Selection of this substitute requires verification of the following application-specific constraints:

Supply voltage compatibility: The DSC1001DL5-020.0000 operates at 1.8V to 3.3V, which overlaps with but does not fully encompass the original part's 2.25V to 3.6V range. Applications requiring operation above 3.3V or below 2.25V cannot use this substitute without circuit redesign.

Operating temperature range: The DSC1001DL5-020.0000 supports -40°C to 105°C, which is narrower than the original part's -55°C to 125°C range. Applications requiring operation below -40°C or above 105°C must evaluate alternative solutions.

Current consumption: The DSC1001DL5-020.0000 exhibits significantly lower active current (6.3mA versus 35mA) and standby current (15µA versus 95µA), providing power efficiency benefits in battery-powered or low-power applications.

Package configuration: The DSC1001DL5-020.0000 uses a 4-VDFN package compared to the original 6-VDFN package. PCB layout modifications are required to accommodate this package change.

Product status: The DSC1001DL5-020.0000 is classified as active with AEC-Q100 certification, ensuring long-term availability and automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can the DSC1001DL5-020.0000 directly replace the DSC1101DM5-020.0000 without circuit modifications?

A: Direct replacement is not possible due to package differences (4-VDFN versus 6-VDFN) and supply voltage range differences. PCB layout redesign is required to accommodate the different pin configuration. Circuit evaluation is necessary to confirm that the 1.8V to 3.3V supply voltage range is compatible with your application.

Q: What are the key electrical differences between these parts?

A: The primary electrical differences are supply voltage range (2.25V–3.6V versus 1.8V–3.3V), operating temperature range (-55°C–125°C versus -40°C–105°C), and current consumption (35mA active and 95µA standby versus 6.3mA active and 15µA standby). Frequency, stability, output type, and resonator technology are identical.

Q: Is the DSC1001DL5-020.0000 suitable for automotive applications?

A: The DSC1001DL5-020.0000 carries AEC-Q100 certification, indicating suitability for automotive applications. The original DSC1101DM5-020.0000 does not list this certification.

Q: What is the impact of the package change from 6-VDFN to 4-VDFN?

A: The 4-VDFN package has fewer pins and a different pin assignment than the 6-VDFN package. This requires complete PCB footprint redesign and schematic verification to ensure correct signal routing and power distribution.

Q: Are both parts RoHS compliant?

A: Yes, both the DSC1101DM5-020.0000 and DSC1001DL5-020.0000 are ROHS3 compliant with MSL rating of 1 (Unlimited).
