Substitute Part Grouping Explanation

Substitution eligibility for the DSC8002CI1 is determined by strict alignment across the following critical parameters:

• Base Resonator type (MEMS)
• Oscillator Type (XO Standard)
• Programmable configuration (Blank, user-programmable)
• Frequency range capability (1 MHz ~ 150 MHz minimum)
• Output logic family (CMOS)
• Supply voltage range (1.8V ~ 3.3V)
• Package form factor (4-SMD, No Lead)
• Physical dimensions (0.126" L x 0.098" W, 0.035" max height)
• Operating temperature range (-40°C ~ 85°C)

The DSC8001CI1 meets all substitution criteria as a direct functional equivalent within the Microchip DSC series programmable oscillator family.

Parameter Comparison

Engineering Selection Recommendations

The DSC8001CI1 is the qualified substitute for the obsolete DSC8002CI1. Both components share identical mechanical packaging, electrical interface specifications, and frequency generation capabilities. The DSC8001CI1 maintains active product status with Microchip Technology, ensuring continued availability and supply chain support.

The DSC8001CI1 carries AEC-Q100 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification, supporting deployment in standard manufacturing environments.

Current consumption differences exist between the two parts: the DSC8002CI1 specifies 10mA maximum supply current and 1 µA disable current, while the DSC8001CI1 specifies 12.2mA maximum supply current and 15 µA disable current. These differences must be evaluated within the context of specific application power budgets.

Frequently Asked Questions (FAQ)

Q: Can the DSC8001CI1 directly replace the DSC8002CI1 in existing designs?

A: Yes. Both components share identical package form factors, pinouts, supply voltage ranges, frequency capabilities, and output logic families. No PCB modifications are required for substitution.

Q: What are the key differences between these two parts?

A: The primary differences are product status and current consumption specifications. The DSC8002CI1 is obsolete; the DSC8001CI1 is active. The DSC8001CI1 draws slightly higher maximum supply current (12.2mA vs. 10mA) and higher disable current (15 µA vs. 1 µA). Frequency stability specifications are equivalent at ±50ppm.

Q: Are there any compliance or certification differences?

A: The DSC8001CI1 includes AEC-Q100 automotive qualification, which the DSC8002CI1 does not specify. Both parts are ROHS3 compliant and REACH unaffected.

Q: Does the package size remain the same?

A: Yes. Both parts use identical 4-SMD, No Lead packaging with dimensions of 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.035" (0.90mm).

Q: Are these parts user-programmable?

A: Yes. Both the DSC8002CI1 and DSC8001CI1 are blank programmable oscillators. End users must program the desired frequency within the 1 MHz to 150 MHz range using appropriate programming tools and procedures.

Q: What is the moisture sensitivity classification?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.
