DSC8002CI2 Equivalent & Substitute Parts

Part Overview

The DSC8002CI2 is a MEMS-based programmable oscillator from Microchip Technology's DSC8002 series, designed for applications requiring flexible frequency generation across the 1 MHz to 150 MHz range. This component operates at supply voltages between 1.8V and 3.3V with CMOS output and includes a standby function for power management. The DSC8002CI2 is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity. Active alternatives within the DSC8001 and DSC8004 series provide direct functional replacement with enhanced product lifecycle status.

All substitute parts listed below meet these criteria and are qualified for direct replacement in applications where the DSC8002CI2 was originally specified.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are qualified for direct replacement of the DSC8002CI2 based on matching electrical, mechanical, and environmental specifications. The DSC8001 series variants (DSC8001CI2, DSC8001CI1, DSC8001CI5) offer the advantage of active product status with AEC-Q100 automotive qualification, providing enhanced lifecycle support and supply chain continuity. The DSC8004CI2 alternative maintains equivalent electrical performance with active status but lacks automotive qualification.

For applications requiring the lowest frequency stability tolerance, DSC8001CI5 (±10ppm) provides superior performance compared to the original DSC8002CI2 specification (±25ppm). For applications with less stringent stability requirements, DSC8001CI1 (±50ppm) is acceptable. Current consumption differences across substitute options range from 12.2mA to 16.6mA during active operation, with standby current consumption increasing from 1 µA to 15 µA. These variations remain within acceptable design margins for most applications utilizing the original part.

Frequently Asked Questions (FAQ)

Q: Can DSC8001CI2 directly replace DSC8002CI2 in existing designs?

A: Yes. DSC8001CI2 matches all mandatory electrical, mechanical, and environmental parameters of DSC8002CI2. The primary difference is product status (Active vs. Obsolete) and the addition of AEC-Q100 automotive qualification. Current consumption increases from 10mA to 12.2mA, and standby current increases from 1 µA to 15 µA. These differences are within typical design margins.

Q: What is the difference between DSC8001CI1, DSC8001CI2, and DSC8001CI5?

A: All three parts are functionally equivalent with identical electrical and mechanical specifications except for frequency stability tolerance. DSC8001CI5 provides ±10ppm stability (tightest tolerance), DSC8001CI2 provides ±25ppm stability (matching original part), and DSC8001CI1 provides ±50ppm stability (loosest tolerance). Selection depends on application frequency accuracy requirements.

Q: Is DSC8004CI2 suitable as a substitute?

A: Yes. DSC8004CI2 meets all mandatory parameters and provides equivalent electrical performance with ±25ppm frequency stability. However, it lacks AEC-Q100 automotive qualification and exhibits higher current consumption (16.6mA active, 15 µA standby). Use DSC8004CI2 only when automotive qualification is not required.

Q: Are there any packaging or PCB layout considerations when switching to substitute parts?

A: No. All substitute parts use identical 4-SMD, No Lead packaging with matching dimensions (3.20mm x 2.50mm) and height (0.90mm). PCB footprints and assembly processes remain unchanged.

Q: Do all substitute parts support the same frequency programming range?

A: Yes. All substitute parts support the full 1 MHz to 150 MHz programmable frequency range with identical CMOS output and standby function capability.

Q: What compliance certifications apply to these substitute parts?

A: All parts are ROHS3 compliant with MSL 1 (Unlimited moisture sensitivity level). DSC8001 series variants include AEC-Q100 automotive qualification. REACH status is unaffected for all parts.
