DSC1001DL5-020.0000 Equivalent & Substitute Parts

Part Overview

The DSC1001DL5-020.0000 is a 20 MHz MEMS oscillator manufactured by Microchip Technology, designed for applications requiring a standard XO (crystal oscillator) with low-voltage operation. This device operates across a 1.8V to 3.3V supply range and includes standby (power down) functionality, making it suitable for battery-powered and portable applications. The part is currently in active production status with AEC-Q100 automotive-grade qualification and full RoHS3 compliance. Equivalent substitute parts are identified based on matching electrical specifications, mechanical compatibility, and functional equivalence to support design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSC1001DL5-020.0000 is determined by strict equivalence across the following critical parameters:

Frequency matching at 20 MHz is mandatory. The oscillator type must remain XO (Standard) with MEMS-based resonator technology. Supply voltage compatibility requires the substitute to operate within the 1.8V to 3.3V range. Frequency stability of ±10ppm must be maintained. Operating temperature range must span -40°C to 105°C minimum. Standby (power down) functionality must be present. Output type compatibility includes both CMOS and LVCMOS standards, as both are functionally equivalent for digital logic interfacing. Physical package dimensions must remain within 2.50mm x 2.00mm x 0.90mm (max height) to ensure PCB layout compatibility. Surface mount mounting type is required. RoHS3 compliance and MSL 1 rating are mandatory for regulatory and handling equivalence.

The ASDMB-20.000MHZ-XY-T from Abracon LLC meets all substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The DSC1001DL5-020.0000 and ASDMB-20.000MHZ-XY-T are electrically and mechanically equivalent for 20 MHz oscillator applications within the specified voltage and temperature ranges. Both parts maintain identical frequency stability, operating temperature performance, and standby current characteristics. Selection between these parts may be based on supply chain availability, lead time, packaging preference (4-VDFN versus 4-SMD, No Lead), or active inventory status.

The Microchip DSC1001DL5-020.0000 carries AEC-Q100 automotive-grade qualification, which may be required for automotive or mission-critical applications. The Abracon ASDMB-20.000MHZ-XY-T does not list AEC-Q100 qualification in the provided specifications.

Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99, meeting standard regulatory requirements for commercial and industrial applications. MSL 1 rating on both parts indicates unlimited shelf life under standard storage conditions.

The primary design consideration is maximum supply current: the Microchip part specifies 6.3mA maximum, while the Abracon part specifies 16mA maximum. In power-sensitive applications, the lower current specification of the Microchip part may be preferred. Both parts deliver identical standby current performance at 15µA maximum.

Frequently Asked Questions (FAQ)

Q: Can the ASDMB-20.000MHZ-XY-T directly replace the DSC1001DL5-020.0000 on an existing PCB?

A: Physical and electrical substitution is possible due to identical package dimensions (2.50mm x 2.00mm x 0.90mm max) and matching pin configurations for 4-lead surface mount packages. However, the package designations differ (4-VDFN versus 4-SMD, No Lead), requiring verification of PCB footprint compatibility with your design documentation. Both parts operate identically across the 1.8V to 3.3V supply range and -40°C to 105°C temperature range.

Q: What is the difference between CMOS and LVCMOS output types?

A: Both CMOS and LVCMOS are compatible output standards for digital logic interfacing. LVCMOS (Low Voltage CMOS) is optimized for lower voltage operation and is functionally equivalent to CMOS within the 1.8V to 3.3V supply range specified for both parts. No circuit modification is required when substituting between these output types for this frequency and voltage class.

Q: Why does the Abracon part have higher maximum supply current (16mA vs 6.3mA)?

A: Maximum supply current specifications reflect worst-case operating conditions and manufacturing tolerances. The higher specification on the Abracon part does not indicate inferior performance but rather a more conservative rating envelope. Typical operating current for both parts will be significantly lower. For power-critical applications, consult detailed datasheets for typical current values under your specific operating conditions.

Q: Are both parts suitable for automotive applications?

A: The Microchip DSC1001DL5-020.0000 carries AEC-Q100 automotive-grade qualification. The Abracon ASDMB-20.000MHZ-XY-T does not list AEC-Q100 qualification in the provided specifications. For automotive or safety-critical applications, the Microchip part is the specified choice. For general industrial and commercial applications, both parts meet ROHS3 and REACH compliance requirements.

Q: What does MSL 1 (Unlimited) mean for handling and storage?

A: MSL 1 (Moisture Sensitivity Level 1) indicates the part has unlimited shelf life under standard storage conditions (typically 23°C ± 2°C and 45% to 75% relative humidity). No special moisture-control packaging or baking procedures are required before soldering. Both parts can be stored and handled using standard component management practices.

Q: Can I use either part interchangeably in a design requiring ±10ppm frequency stability?

A: Yes. Both the DSC1001DL5-020.0000 and ASDMB-20.000MHZ-XY-T specify ±10ppm frequency stability across the operating temperature range. Frequency stability performance is equivalent between the two parts, and either part will meet timing requirements for applications specified to ±10ppm tolerance.
