Substitute Part Grouping Explanation

Substitution for the DSC6111CI1A-000.0000 is determined by strict equivalence across the following critical parameters:

Base Resonator: MEMS
Type: XO (Standard)
Output: CMOS
Available Frequency Range: 1 MHz ~ 100 MHz
Voltage - Supply: 1.71V ~ 3.63V
Operating Temperature: -40°C ~ 85°C
Package / Case: 4-SMD, No Lead
Size / Dimension: 0.126" L x 0.098" W (3.20mm x 2.50mm)
Height - Seated (Max): 0.035" (0.90mm)
Mounting Type: Surface Mount
Current - Supply (Max): 3mA (Typ)
Current - Supply (Disable) (Max): 12 µA
Ratings: AEC-Q100
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)
REACH Status: REACH Unaffected

The substitute parts DSC6112CI1A-000.0000 and DSC6112CI2A-000.0000 maintain full parametric equivalence across all mechanical and electrical specifications. Variation in frequency stability (±50ppm for DSC6111CI1A and DSC6112CI1A; ±25ppm for DSC6112CI2A) represents a tighter tolerance option and does not preclude substitution where the original specification is met.

Engineering Selection Recommendations

All three parts—DSC6111CI1A-000.0000, DSC6112CI1A-000.0000, and DSC6112CI2A-000.0000—are classified as obsolete products. Selection among these equivalents should be based on current inventory availability and compliance requirements.

All parts carry AEC-Q100 automotive-grade ratings, ROHS3 compliance, and REACH unaffected status, making them suitable for applications requiring automotive or industrial qualification. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

DSC6112CI2A-000.0000 offers improved frequency stability at ±25ppm compared to the ±50ppm specification of the other two parts. This tighter tolerance may be selected where frequency accuracy is a design requirement, provided inventory is available.

Frequently Asked Questions (FAQ)

Q: Can DSC6112CI1A-000.0000 or DSC6112CI2A-000.0000 be used as direct replacements for DSC6111CI1A-000.0000?
