DSC8102CI5 Equivalent & Substitute Parts

Part Overview

The DSC8102CI5 is a MEMS-based programmable oscillator manufactured by Microchip Technology, designed for applications requiring flexible frequency generation across a wide range from 10 MHz to 460 MHz. This XO (Standard) oscillator operates at 2.25V to 3.6V supply voltage with LVPECL output and includes standby functionality. The part is classified as Active product status with AEC-Q100 automotive-grade qualification and ROHS3 compliance. Finding equivalent substitute parts is necessary when the primary part experiences supply constraints, inventory limitations, or when design flexibility requires alternative frequency stability specifications while maintaining core electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the DSC8102CI5 is determined by strict adherence to the following critical parameters:

• Manufacturer and Series: Must be Microchip Technology DSC8102 series to ensure firmware compatibility and pinout alignment
• Base Resonator Technology: Must be MEMS-based to maintain frequency stability characteristics and programmability
• Oscillator Type: Must be XO (Standard) with Blank programmable configuration
• Frequency Range: Must support the full 10 MHz to 460 MHz range
• Output Standard: Must be LVPECL to ensure signal compatibility with receiving circuits
• Supply Voltage: Must operate within 2.25V to 3.6V range
• Operating Temperature: Must support -40°C to 85°C operating window
• Package and Mechanical: Must be 6-SMD, No Lead with identical footprint dimensions (3.20mm x 2.50mm x 0.90mm max height)
• Compliance and Ratings: Must maintain AEC-Q100 qualification, ROHS3 compliance, and MSL 1 rating

The DSC8102CI2 qualifies as a parametric equivalent substitute. The only variance is in frequency stability specification (±25ppm versus ±10ppm), which does not affect substitution eligibility as both parts share identical electrical interfaces, mechanical compatibility, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the DSC8102CI5 and DSC8102CI2 are Active product status components from Microchip Technology with identical AEC-Q100 automotive-grade qualification and ROHS3 compliance certification. Selection between these parts should be based on application-specific frequency stability requirements. The DSC8102CI5 provides ±10ppm frequency stability, while the DSC8102CI2 provides ±25ppm frequency stability. Both parts maintain full electrical and mechanical compatibility, identical pinout configuration, and equivalent thermal operating range. Component selection should prioritize availability and inventory status while confirming that the specified frequency stability meets system-level timing accuracy requirements.

Frequently Asked Questions (FAQ)

Q: Can DSC8102CI2 be used as a direct replacement for DSC8102CI5?

A: Yes, the DSC8102CI2 is a parametric equivalent substitute. Both parts share identical electrical interfaces, mechanical footprint, supply voltage requirements, frequency range capability, and output characteristics. The primary difference is frequency stability specification (±25ppm versus ±10ppm). Substitution is valid when application timing requirements can tolerate the wider stability tolerance of the DSC8102CI2.

Q: Are there any pinout or footprint differences between these parts?

A: No. Both parts use identical 6-SMD, No Lead packaging with matching dimensions of 3.20mm x 2.50mm x 0.90mm maximum height. PCB layout and reflow profiles are interchangeable.

Q: Do both parts require user programming?

A: Yes. Both DSC8102CI5 and DSC8102CI2 are Blank programmable oscillators. End users must program the desired output frequency within the 10 MHz to 460 MHz range using Microchip's programming tools and methodology.

Q: What is the significance of the frequency stability difference?

A: Frequency stability (±10ppm for DSC8102CI5 versus ±25ppm for DSC8102CI2) defines the maximum frequency deviation over the operating temperature range and supply voltage variation. Applications with stringent timing requirements should use the DSC8102CI5. Applications with relaxed timing tolerances can use the DSC8102CI2.

Q: Are both parts AEC-Q100 qualified?

A: Yes. Both DSC8102CI5 and DSC8102CI2 carry AEC-Q100 automotive-grade qualification and are suitable for automotive and industrial applications requiring reliability certification.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
