DSC8002DI2 Equivalent & Substitute Parts

Part Overview

The DSC8002DI2 is a MEMS-based programmable oscillator from Microchip Technology's DSC8002 series, designed for applications requiring user-programmable frequency output in the 1 MHz to 150 MHz range. This component operates at 1.8V to 3.3V supply voltage with CMOS output and includes a standby function for power management. The DSC8002DI2 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DSC8002DI2 is determined by the following critical parameters:

Core Compatibility Parameters:

• Base Resonator: MEMS
• Type: XO (Standard)
• Programmable Type: Blank (User Must Program)
• Available Frequency Range: 1 MHz ~ 150 MHz
• Output: CMOS
• Voltage - Supply: 1.8V ~ 3.3V
• Operating Temperature: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, No Lead
• Physical Dimensions: 0.098" L x 0.079" W (2.50mm x 2.00mm)

Allowable Variation Parameters:

• Frequency Stability (Total): ±10ppm to ±50ppm (tighter tolerance acceptable)
• Current - Supply (Max): Up to 12.2mA (higher current acceptable)
• Current - Supply (Disable) (Max): Up to 15 µA (higher standby current acceptable)

All substitute parts listed maintain identical core functionality, frequency range, voltage specifications, and physical form factor as the DSC8002DI2.

Parameter Comparison

Engineering Selection Recommendations

DSC8001DI2 is the primary direct substitute for DSC8002DI2. Both parts share identical frequency range, voltage specifications, and physical dimensions. DSC8001DI2 is active in production with AEC-Q100 automotive qualification and improved moisture sensitivity rating (MSL 1). Current consumption increases to 12.2mA maximum and standby current to 15 µA, both within acceptable operational margins for most applications.

DSC8001DI1 provides parametric equivalence with relaxed frequency stability (±50ppm versus ±25ppm). This part is active with AEC-Q100 certification and MSL 1 rating. Selection is appropriate for applications where ±50ppm stability meets system requirements.

DSC8001DI5 offers the tightest frequency stability specification (±10ppm) among all substitutes. This part is active with AEC-Q100 certification and MSL 1 rating. Selection is appropriate for applications requiring superior frequency accuracy.

DSC8002DI1 maintains the same series designation as the original part with active product status. Frequency stability is ±50ppm. Current specifications match the original DSC8002DI2 (10mA maximum, 1 µA standby). This part is suitable for applications where series consistency and original current specifications are preferred.

All substitute parts maintain ROHS3 compliance and REACH unaffected status. Selection between substitutes depends on specific application requirements for frequency stability, automotive qualification, and moisture sensitivity handling.

Frequently Asked Questions (FAQ)

Q: Can DSC8001DI2 directly replace DSC8002DI2 in existing designs?

A: Yes. DSC8001DI2 maintains identical frequency range (1 MHz ~ 150 MHz), voltage supply (1.8V ~ 3.3V), CMOS output, and 4-SMD package dimensions. The primary differences are increased maximum current consumption (12.2mA versus 10mA) and standby current (15 µA versus 1 µA), which are acceptable in most circuit designs. DSC8001DI2 is active in production with AEC-Q100 certification.

Q: What is the difference between DSC8001DI1, DSC8001DI2, and DSC8001DI5?

A: These parts differ in frequency stability specification. DSC8001DI2 provides ±25ppm stability (matching the original DSC8002DI2). DSC8001DI1 offers ±50ppm stability for applications with relaxed accuracy requirements. DSC8001DI5 provides ±10ppm stability for applications requiring superior frequency accuracy. All three are active with AEC-Q100 certification and MSL 1 rating.

Q: Does moisture sensitivity level affect substitution compatibility?

A: Moisture sensitivity level (MSL) affects component handling and storage requirements but does not affect electrical functionality or pin compatibility. DSC8002DI2 and DSC8002DI1 have MSL 3 (168 hours), while DSC8001 series parts have MSL 1 (unlimited). MSL 1 components offer superior moisture tolerance and are preferred for long-term storage and humid environments.

Q: Are all substitute parts AEC-Q100 qualified?

A: DSC8001DI2, DSC8001DI1, and DSC8001DI5 carry AEC-Q100 automotive qualification. DSC8002DI1 does not have AEC-Q100 certification. For automotive applications, DSC8001 series substitutes are recommended.

Q: Can I use DSC8002DI1 as a substitute for DSC8002DI2?

A: Yes. DSC8002DI1 maintains the same series, package, and current specifications as DSC8002DI2. The primary difference is frequency stability (±50ppm versus ±25ppm). DSC8002DI1 is active in production and suitable for applications where ±50ppm stability is acceptable.

Q: What are the key parameters that must remain identical for substitution?

A: Core parameters that must remain identical are: MEMS base resonator, XO (Standard) type, blank programmable type, 1 MHz ~ 150 MHz frequency range, CMOS output, 1.8V ~ 3.3V supply voltage, -40°C ~ 85°C operating temperature, surface mount mounting, 4-SMD no-lead package, and 2.50mm x 2.00mm x 0.90mm maximum dimensions. Frequency stability, current consumption, and moisture sensitivity may vary within specified ranges.
