Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the DSC1101 series maintain electrical and mechanical compatibility through identical specifications in the following critical parameters:

• Frequency Range: 2.3 MHz ~ 170 MHz
• Supply Voltage: 2.25V ~ 3.6V
• Output Type: CMOS
• Maximum Supply Current: 35mA
• Operating Temperature Range: -40°C ~ 105°C
• Package Type: 6-VDFN Exposed Pad
• Physical Dimensions: 7.00mm x 5.00mm x 0.90mm (max height)
• Mounting: Surface Mount
• Compliance: ROHS3, REACH Unaffected, MSL 1

Substitution is permitted when these parameters remain constant across part variants. Variations in frequency stability specifications do not preclude substitution when the application requirements are met by either tolerance grade.

Parameter Comparison

Engineering Selection Recommendations

Both DSC1101AL3-PROGT and DSC1101AL5-PROGT are active production parts from Microchip Technology with full ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by frequency stability requirements:

• DSC1101AL3-PROGT: Suitable for applications tolerating ±20ppm frequency stability
• DSC1101AL5-PROGT: Required for applications demanding ±10ppm frequency stability

Both parts share identical electrical performance, mechanical dimensions, package configuration, and thermal operating range. PCB layout, footprint design, and programming interfaces are interchangeable. The DSC1101AL5-PROGT offers superior frequency stability performance and is currently available in higher inventory quantity (1659 units versus 794 units).

Frequently Asked Questions (FAQ)

Q: Can DSC1101AL3-PROGT and DSC1101AL5-PROGT be used interchangeably on the same PCB?

A: Yes. Both parts use identical 6-VDFN Exposed Pad packaging with matching footprint dimensions (7.00mm x 5.00mm x 0.90mm max height). PCB layout and solder reflow profiles are compatible without modification.

Q: What is the primary difference between these two part numbers?

A: The frequency stability specification differs. DSC1101AL3-PROGT provides ±20ppm stability, while DSC1101AL5-PROGT provides ±10ppm stability. All other electrical and mechanical parameters are identical.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both parts operate across the -40°C to 105°C temperature range, meeting industrial specifications.

Q: Do these parts require external programming?

A: Yes. Both are blank programmable oscillators. User programming is required to set the desired output frequency within the 2.3 MHz to 170 MHz range.

Q: What is the supply voltage requirement?

A: Both parts operate at 2.25V to 3.6V supply voltage with maximum supply current of 35mA.

Q: Are these parts RoHS compliant?

A: Yes. Both DSC1101AL3-PROGT and DSC1101AL5-PROGT are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Which part should be selected for new designs?

A: Selection depends on frequency stability requirements. For applications requiring tighter frequency tolerance, DSC1101AL5-PROGT with ±10ppm stability is the appropriate choice. Both parts are in active production status.
