Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN7500050 is determined by strict equivalence across the following critical parameters:

• Frequency: 75 MHz (exact match required)
• Output Configuration: CMOS logic level
• Supply Voltage: 1.8V operation
• Functional Control: Enable/Disable capability
• Package Specification: 4-SMD, No Lead form factor
• Physical Dimensions: 7.00mm x 5.00mm footprint with 1.55mm maximum height
• Operating Temperature: -40°C to 85°C range
• Current Specifications: 20mA maximum supply current and 100µA disable current
• Compliance: ROHS3 Compliant status

The FN7500051 meets all these criteria as a parametric equivalent within the SaRonix-eCera™ FN series, maintaining identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both FN7500050 and FN7500051 are active production parts from Diodes Incorporated with identical ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain considerations rather than technical differentiation. The FN7500051 currently maintains higher inventory levels (1098 pcs vs 772 pcs), which may influence procurement decisions for high-volume applications. Both parts carry ECCN EAR99 classification and HTSUS code 8542.39.0001, indicating equivalent regulatory treatment. PCB layout and assembly processes require no modification when substituting between these parts due to identical package specifications and pin configurations.
