Substitute Part Grouping Explanation

The EXC-24CE900U qualifies as a direct substitute for the EXC-24CD900U based on the following critical parameters:

Matching Parameters:

• Number of Lines: 2
• Impedance @ Frequency: 90 Ohms @ 100 MHz
• Current Rating (Max): 160mA
• Voltage Rating - DC: 5V
• Mounting Type: Surface Mount
• Package / Case: 0504 (1210 Metric), 4 Lead
• Physical Dimensions: 0.049" L x 0.039" W (1.25mm x 1.00mm)
• Height (Max): 0.024" (0.60mm)
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation:

• DC Resistance (DCR): EXC-24CE900U has a maximum DCR of 1.75 Ohm compared to 2 Ohm in the original part. This represents an improvement in electrical performance and is acceptable for substitution.
