DSC8102AI5 Equivalent & Substitute Parts

Part Overview

The DSC8102AI5 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 device is classified as a blank programmable unit, requiring user programming to set the desired output frequency. With active product status and AEC-Q100 automotive qualification, the DSC8102AI5 serves critical timing applications in automotive, industrial, and communication systems. Identifying equivalent substitute parts is essential for supply chain continuity, inventory optimization, and design flexibility when the primary part becomes unavailable or when alternative packaging or performance specifications better suit project requirements.

Key Parameters

Substitute Part Grouping Explanation

The DSC8102AI2 qualifies as a parametric equivalent to the DSC8102AI5 based on the following substitution criteria:

Core Electrical Compatibility:

• Identical MEMS base resonator technology and XO (Standard) oscillator type
• Matching frequency range: 10 MHz ~ 460 MHz
• Identical supply voltage range: 2.25V ~ 3.6V
• Identical LVPECL output configuration
• Identical standby function capability
• Identical maximum supply current: 58mA
• Identical operating temperature range: -40°C ~ 85°C

Mechanical & Package Compatibility:

• Identical 6-SMD, No Lead package configuration
• Identical physical dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Identical seated height: 0.035" (0.90mm)

Compliance & Certification:

• Both devices maintain AEC-Q100 automotive qualification
• Both are ROHS3 compliant
• Both are REACH unaffected

Allowable Variation:

• Frequency Stability (Total): DSC8102AI5 specifies ±10ppm; DSC8102AI2 specifies ±25ppm. This represents a relaxation of the stability specification and is acceptable for applications where the tighter tolerance is not required.
• Moisture Sensitivity Level (MSL): DSC8102AI5 is MSL 3 (168 Hours); DSC8102AI2 is MSL 1 (Unlimited). The DSC8102AI2 offers superior moisture resistance characteristics.
• Packaging format: DSC8102AI5 is supplied in standard packaging; DSC8102AI2 is supplied in Tube packaging. Both are suitable for automated assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (DSC8102AI5): Select the DSC8102AI5 when your application requires the tighter frequency stability specification of ±10ppm. This part is suitable for timing-critical applications where frequency accuracy directly impacts system performance. The standard packaging format is appropriate for typical inventory and assembly workflows.

Substitute Selection (DSC8102AI2): The DSC8102AI2 is a direct substitute when frequency stability of ±25ppm meets application requirements. This part offers two distinct advantages: superior moisture resistance (MSL 1 versus MSL 3) and availability in Tube packaging, which may provide cost or logistics benefits. Both parts maintain identical AEC-Q100 automotive qualification and ROHS3 compliance, ensuring regulatory and quality standards are preserved across substitution.

Substitution Validity: Both parts are active products from Microchip Technology with identical electrical interfaces, mechanical compatibility, and compliance certifications. The substitution is valid at the component level for any design currently using the DSC8102AI5, provided the relaxed frequency stability specification of the DSC8102AI2 does not violate system-level timing requirements.

Frequently Asked Questions (FAQ)

Q: Can the DSC8102AI2 be used as a direct replacement for the DSC8102AI5 in existing designs?

A: Yes, the DSC8102AI2 is a direct mechanical and electrical substitute. Both parts share identical package dimensions, pinout, supply voltage range, frequency range, output type, and operating temperature. The primary difference is frequency stability specification (±25ppm versus ±10ppm). Substitution is valid if your application does not require the tighter ±10ppm tolerance.

Q: What is the significance of the frequency stability difference between these parts?

A: Frequency stability defines how much the output frequency can deviate from the programmed value over time and temperature. The DSC8102AI5 guarantees ±10ppm stability, while the DSC8102AI2 guarantees ±25ppm. Applications requiring precise frequency control (such as high-speed data communications or precision timing) should use the DSC8102AI5. Applications with relaxed frequency requirements can use the DSC8102AI2.

Q: Why does the DSC8102AI2 have a lower Moisture Sensitivity Level (MSL 1 versus MSL 3)?

A: MSL rating indicates how long a component can be exposed to moisture before soldering without degradation. MSL 1 (Unlimited) means the DSC8102AI2 has superior moisture resistance and can be stored indefinitely without special drying procedures. MSL 3 (168 Hours) for the DSC8102AI5 requires desiccant storage and baking before assembly if storage exceeds 168 hours. The DSC8102AI2 offers simplified handling and storage logistics.

Q: Are both parts suitable for automotive applications?

A: Yes, both the DSC8102AI5 and DSC8102AI2 carry AEC-Q100 automotive qualification, confirming they meet automotive industry reliability and quality standards. Both are suitable for automotive timing applications.

Q: What is the difference between standard packaging and Tube packaging?

A: Standard packaging typically refers to tape-and-reel format optimized for automated pick-and-place assembly. Tube packaging contains components in a plastic tube, suitable for manual assembly or lower-volume production. Both packaging formats are compatible with the same component specifications and performance characteristics.

Q: Are there any design considerations when switching from DSC8102AI5 to DSC8102AI2?

A: The only design consideration is verifying that your application can tolerate the relaxed frequency stability of ±25ppm. Electrical interface, mechanical fit, and thermal performance are identical. No PCB layout changes or firmware modifications are required.

Q: Do both parts require user programming?

A: Yes, both the DSC8102AI5 and DSC8102AI2 are blank programmable oscillators. The user must program the desired output frequency within the 10 MHz to 460 MHz range before deployment. Programming procedures and capabilities are identical between both parts.
