Substitute Part Grouping Explanation

The DSC8103AI2 qualifies as a parametric equivalent to the DSC8103AI5 based on the following critical substitution criteria:

Matching Parameters (Substitution Basis):

• Identical manufacturer (Microchip Technology)
• Same series designation (DSC8103)
• Identical base resonator technology (MEMS)
• Identical oscillator type (XO Standard)
• Identical output format (LVDS)
• Identical frequency range (10 MHz ~ 460 MHz)
• Identical supply voltage range (2.25V ~ 3.6V)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical package and mounting specifications (6-SMD, No Lead, Surface Mount)
• Identical physical dimensions (7.00mm x 5.00mm x 0.90mm max height)
• Identical maximum supply current (32mA)
• Identical AEC-Q100 qualification
• Identical RoHS3 compliance status

Differing Parameters (Non-Critical for Substitution):

• Frequency Stability (Total): DSC8103AI5 specifies ±10ppm; DSC8103AI2 specifies ±25ppm
• Moisture Sensitivity Level (MSL): DSC8103AI5 is MSL 3 (168 Hours); DSC8103AI2 is MSL 1 (Unlimited)

Both parts share the same blank programmable configuration, requiring user programming for frequency selection. The substitute relationship is valid for applications where the relaxed frequency stability tolerance of ±25ppm and improved moisture handling of MSL 1 are acceptable.

Parameter Comparison

Engineering Selection Recommendations

DSC8103AI5 Selection Criteria: Select the DSC8103AI5 when applications require tighter frequency stability tolerance of ±10ppm. This part maintains active product status and AEC-Q100 qualification. The MSL 3 rating (168 hours) is suitable for standard manufacturing environments with controlled moisture exposure.

DSC8103AI2 Selection Criteria: The DSC8103AI2 serves as a direct substitute when the relaxed frequency stability tolerance of ±25ppm meets application requirements. This variant offers superior moisture handling with MSL 1 (Unlimited) rating, eliminating moisture sensitivity constraints during storage and assembly. Both parts maintain identical AEC-Q100 automotive qualification and ROHS3 compliance, ensuring equivalent reliability and regulatory compliance across automotive and industrial applications.

Substitution Validity: Both parts are manufactured by Microchip Technology with active product status. The electrical and mechanical compatibility is complete. Selection between these variants depends solely on the application's frequency stability tolerance requirement and moisture sensitivity handling needs during manufacturing and storage.

Frequently Asked Questions (FAQ)

Q: Can DSC8103AI2 replace DSC8103AI5 in existing designs? A: Yes, the DSC8103AI2 is a direct parametric equivalent. Both parts share identical electrical specifications, package dimensions, mounting type, and supply voltage requirements. The primary difference is frequency stability tolerance (±25ppm vs ±10ppm) and moisture sensitivity level. Substitution is valid if the application tolerates ±25ppm frequency stability.

Q: What is the significance of the frequency stability difference? A: The DSC8103AI5 maintains ±10ppm frequency stability, while the DSC8103AI2 specifies ±25ppm. Applications requiring precise frequency control should use the DSC8103AI5. Applications with relaxed frequency tolerance can use the DSC8103AI2 without performance degradation.

Q: How does the Moisture Sensitivity Level (MSL) affect part selection? A: MSL 3 (DSC8103AI5) allows 168 hours of exposure to 30°C/85% RH before baking is required. MSL 1 (DSC8103AI2) has unlimited moisture exposure tolerance. For high-volume manufacturing or extended storage periods, the DSC8103AI2 eliminates moisture-related handling constraints.

Q: Are both parts AEC-Q100 qualified? A: Yes, both DSC8103AI5 and DSC8103AI2 carry AEC-Q100 automotive qualification, ensuring equivalent reliability for automotive and industrial applications.

Q: Can these parts be used interchangeably on the same PCB assembly? A: Yes, both parts use identical 6-SMD, No Lead packaging with matching footprints (7.00mm x 5.00mm x 0.90mm max height). PCB layout and assembly processes require no modification for substitution.

Q: What is the programmable blank configuration? A: Both parts are supplied as blank oscillators requiring user programming to set the desired output frequency within the 10 MHz to 460 MHz range. Programming capability is identical between both variants.

Q: Do both parts support the same voltage supply range? A: Yes, both DSC8103AI5 and DSC8103AI2 operate across the identical 2.25V to 3.6V supply voltage range with maximum supply current of 32mA.
