DSC1101DM5-020.0000T Equivalent & Substitute Parts

Part Overview

The DSC1101DM5-020.0000T is a 20 MHz MEMS-based XO (Standard) CMOS oscillator manufactured by Microchip Technology. This component operates across a 2.25V to 3.6V supply range and features standby (power down) functionality. The device is packaged in a 6-VDFN surface mount configuration with dimensions of 2.50mm × 2.00mm and a maximum seated height of 0.90mm.

The DSC1101DM5-020.0000T is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this oscillator.

Key Parameters

Substitute Part Grouping Explanation

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

• Frequency: 20 MHz (exact match required)
• Base Resonator: MEMS technology
• Type: XO (Standard)
• Output: CMOS
• Frequency Stability: ±10ppm
• Mounting Type: Surface Mount
• Physical Compatibility: Footprint and height constraints

The DSC1001DL5-020.0000 qualifies as a substitute based on matching frequency, resonator type, oscillator type, output format, and frequency stability. However, differences exist in supply voltage range, operating temperature range, package configuration, and current consumption characteristics. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The DSC1001DL5-020.0000 is an active product with current manufacturing support from Microchip Technology, whereas the DSC1101DM5-020.0000T is obsolete. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Selection of the DSC1001DL5-020.0000 as a substitute requires verification that the application supply voltage range of 1.8V ~ 3.3V is compatible with the original design specification of 2.25V ~ 3.6V. The substitute operates within a narrower voltage window and reduced temperature range (-40°C ~ 105°C versus -55°C ~ 125°C). The substitute exhibits significantly lower current consumption (6.3mA maximum versus 35mA maximum) and lower disable current (15µA versus 95µA).

Package configuration differs: the substitute uses 4-VDFN versus the original 6-VDFN. Physical footprint dimensions remain identical at 2.50mm × 2.00mm with 0.90mm maximum seated height, but pin count and layout differ. PCB layout and schematic modifications are required to accommodate the package change.

Frequently Asked Questions (FAQ)

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

A: No. The substitute uses a 4-VDFN package versus the original 6-VDFN package. Pin count and pinout differ, requiring PCB layout and schematic modifications.

Q: What are the critical compatibility factors for substitution?

A: Frequency (20 MHz), base resonator technology (MEMS), oscillator type (XO Standard), output format (CMOS), and frequency stability (±10ppm) must match. Supply voltage range, operating temperature range, and current consumption must be evaluated against application requirements.

Q: Does the substitute meet the original operating temperature range?

A: No. The DSC1001DL5-020.0000 operates from -40°C to 105°C, whereas the original part operates from -55°C to 125°C. Applications requiring the full -55°C to 125°C range cannot use this substitute without design modification or alternative component selection.

Q: Is the substitute compatible with the original supply voltage specification?

A: Partial compatibility exists. The substitute operates from 1.8V to 3.3V, while the original operates from 2.25V to 3.6V. Applications operating at 2.25V to 3.3V are compatible. Applications requiring operation above 3.3V or below 2.25V require alternative component selection.

Q: What are the power consumption differences?

A: The substitute consumes significantly less power: 6.3mA maximum active current versus 35mA, and 15µA disable current versus 95µA. This represents a substantial reduction in power dissipation.

Q: Are both components RoHS compliant?

A: Yes. Both the DSC1101DM5-020.0000T and DSC1001DL5-020.0000 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings.
