Substitute Part Grouping Explanation

The DSC8103CI5 qualifies as a parametric equivalent to the DSC8103CI2 based on the following substitution criteria:

Matching Parameters (Substitution Basis):

Identical base resonator technology (MEMS)
Identical oscillator type (XO Standard)
Identical output configuration (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 maximum supply current (32mA)
Identical package type and dimensions (6-SMD, No Lead; 3.20mm x 2.50mm)
Identical programmable configuration (Blank, user-programmed)
Identical standby function capability
Identical compliance ratings (AEC-Q100, ROHS3, MSL 1)

Differing Parameter:

Frequency Stability (Total): DSC8103CI2 specifies ±25ppm; DSC8103CI5 specifies ±10ppm

The DSC8103CI5 provides tighter frequency stability, making it suitable for applications where the DSC8103CI2 is unavailable or where improved stability performance is acceptable or beneficial.

Engineering Selection Recommendations

Both the DSC8103CI2 and DSC8103CI5 are active production parts from Microchip Technology with identical compliance certifications (AEC-Q100, ROHS3 Compliant, MSL 1). Both parts share the same mechanical footprint, electrical interface, and functional capabilities within the DSC8103 series.

Selection between these parts depends on application-specific frequency stability requirements:

DSC8103CI2 is appropriate for applications where ±25ppm frequency stability meets system specifications.
DSC8103CI5 is appropriate for applications where ±10ppm frequency stability is required or where tighter stability provides design margin.

Both parts are suitable for automotive-grade applications (AEC-Q100 rated) and comply with environmental regulations (ROHS3, REACH Unaffected). The DSC8103CI5 currently has higher inventory availability (952 units versus 740 units).

Frequently Asked Questions (FAQ)

Q: Can DSC8103CI5 be used as a direct replacement for DSC8103CI2?

A: Yes. The DSC8103CI5 is mechanically and electrically compatible with the DSC8103CI2. Both parts use identical 6-SMD, No Lead packaging with the same footprint dimensions (3.20mm x 2.50mm x 0.90mm max height). Both operate across the same frequency range (10 MHz ~ 460 MHz), supply voltage (2.25V ~ 3.6V), and temperature range (-40°C ~ 85°C). The primary difference is frequency stability specification: DSC8103CI5 provides ±10ppm versus DSC8103CI2's ±25ppm.

Q: What is the key difference between these two parts?

A: The frequency stability specification differs. DSC8103CI2 specifies ±25ppm total frequency stability, while DSC8103CI5 specifies ±10ppm total frequency stability. All other electrical and mechanical parameters are identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both DSC8103CI2 and DSC8103CI5 carry AEC-Q100 ratings, qualifying them for automotive-grade applications.

Q: Do these parts require programming?

A: Yes. Both parts are supplied as blank programmable oscillators. User programming is required to set the desired output frequency within the 10 MHz ~ 460 MHz range before deployment.

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.

Q: Are these parts RoHS compliant?

A: Yes. Both DSC8103CI2 and DSC8103CI5 are ROHS3 Compliant and REACH Unaffected.
