DSC8002AI2 Equivalent & Substitute Parts

Part Overview

The DSC8002AI2 is a MEMS-based programmable oscillator manufactured by Microchip Technology, operating across the 1 MHz to 150 MHz frequency range with CMOS output. This part functions as a standard XO (Crystal Oscillator) with user-programmable blank configuration, requiring end-user frequency programming. The device operates from 1.8V to 3.3V supply voltage and includes standby functionality with 1 µA disable current consumption.

The DSC8002AI2 carries an Obsolete product status. Identification of equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements. Active alternatives within the Microchip DSC8001 series provide direct functional replacement with enhanced specifications and ongoing manufacturer support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DSC8002AI2 is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Base Resonator Type: MEMS
• Oscillator Type: XO (Standard)
• Programmable Configuration: Blank (User Must Program)
• Frequency Range: 1 MHz ~ 150 MHz
• Output Type: CMOS
• Supply Voltage: 1.8V ~ 3.3V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 4-SMD, No Lead
• Package Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Frequency Stability (Total): Tighter tolerances (lower ppm values) are acceptable
• Current - Supply (Max): Higher values are acceptable within design margins
• Current - Supply (Disable) (Max): Higher values are acceptable
• Product Status: Active alternatives preferred over Obsolete
• Ratings: AEC-Q100 certification adds value but is not mandatory for substitution

All four substitute parts (DSC8001AI2, DSC8001AI1, DSC8001AI5, DSC8002AI1) meet the mandatory matching criteria and are therefore valid equivalents for the DSC8002AI2.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: DSC8001AI2

The DSC8001AI2 is the preferred substitute for the obsolete DSC8002AI2. This part maintains identical electrical and mechanical specifications while offering Active product status with ongoing manufacturer support. The DSC8001AI2 carries AEC-Q100 automotive qualification, providing enhanced reliability documentation. Current consumption increases from 10mA to 12.2mA and disable current from 1 µA to 15 µA; these variations remain within acceptable design margins for most applications. Frequency stability remains at ±25ppm, matching the original specification.

Secondary Recommendation: DSC8001AI5

The DSC8001AI5 provides superior frequency stability at ±10ppm, representing a tighter tolerance than the original ±25ppm specification. This part is suitable for applications requiring enhanced frequency accuracy. The DSC8001AI5 carries Active product status and AEC-Q100 certification. Current consumption specifications are identical to DSC8001AI2. This part is appropriate for designs where improved frequency stability provides system-level benefits.

Tertiary Recommendation: DSC8001AI1

The DSC8001AI1 offers Active product status and AEC-Q100 certification but features relaxed frequency stability at ±50ppm. This part is suitable only for applications where the original ±25ppm specification can be relaxed without system impact. Current consumption specifications match DSC8001AI2.

Alternative: DSC8002AI1

The DSC8002AI1 remains within the same DSC8002 series as the original part but carries Obsolete status. This part matches the original current consumption specifications (10mA max, 1 µA disable) but features relaxed frequency stability at ±50ppm. This part is not recommended for new designs due to obsolete status; however, it may be considered for existing inventory management where DSC8001 series parts are unavailable.

Frequently Asked Questions (FAQ)

Q: Can DSC8001AI2 be used as a direct replacement for DSC8002AI2 without PCB modifications?

A: Yes. The DSC8001AI2 maintains identical package type (4-SMD, No Lead), dimensions (7.00mm x 5.00mm), height (0.90mm max), and mounting type (Surface Mount). No PCB layout changes are required. Pin-to-pin compatibility is maintained.

Q: What is the impact of increased current consumption in DSC8001AI2 compared to DSC8002AI2?

A: The DSC8001AI2 maximum supply current increases from 10mA to 12.2mA, a 22% increase. The disable current increases from 1 µA to 15 µA. These variations must be evaluated within the context of system power budgets and thermal design. For most applications, this increase remains within acceptable margins.

Q: Why does DSC8001AI5 have tighter frequency stability than the original DSC8002AI2?

A: The DSC8001AI5 is specified at ±10ppm frequency stability compared to the original ±25ppm. This represents a manufacturing improvement within the DSC8001 series. Tighter tolerance specifications are acceptable substitutes for applications originally designed to the ±25ppm specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts (DSC8001AI2, DSC8001AI1, DSC8001AI5, DSC8002AI1) are ROHS3 compliant, matching the original DSC8002AI2 compliance status.

Q: What is the significance of AEC-Q100 certification on DSC8001 series parts?

A: AEC-Q100 certification indicates automotive-grade qualification and enhanced reliability testing. The DSC8001 series parts carry this certification, while the original DSC8002AI2 does not. This certification adds value for applications requiring automotive or high-reliability standards.

Q: Can DSC8002AI1 be used instead of DSC8001AI2?

A: DSC8002AI1 is functionally compatible but carries Obsolete product status. For new designs or long-term production, DSC8001 series parts are preferred due to Active status and ongoing manufacturer support. DSC8002AI1 may be considered only when DSC8001 alternatives are unavailable.

Q: What is the difference between "Blank (User Must Program)" and other programmable configurations?

A: All substitute parts maintain the Blank (User Must Program) configuration, identical to the original DSC8002AI2. This means the oscillator frequency must be programmed by the end user during manufacturing or integration. No pre-programmed frequency alternatives are available within this substitution group.

Q: Are moisture sensitivity levels identical across all parts?

A: Yes. All parts, including the original DSC8002AI2 and all substitutes, carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
