Substitute Part Grouping Explanation

The FD5000040 has one identified substitute: the 7C-50.000MCB-T manufactured by TXC CORPORATION. This substitution is valid based on the following critical parameters that must remain constant:

• Frequency: 50 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Package Dimensions: 5.00mm x 3.20mm (exact match required)
• Frequency Stability: ±50ppm (exact match required)

The 7C-50.000MCB-T meets all critical electrical and mechanical parameters, making it a direct functional equivalent for the FD5000040 in applications where these specifications are required.

Parameter Comparison

Engineering Selection Recommendations

Both the FD5000040 and 7C-50.000MCB-T are Active products with full regulatory compliance. The FD5000040 supports a wider operating temperature range (-20°C to 70°C) compared to the 7C-50.000MCB-T (-10°C to 70°C). Applications requiring operation below -10°C must use the FD5000040. The 7C-50.000MCB-T offers lower maximum supply current (30mA versus 35mA), which may provide power efficiency benefits in battery-operated designs. Both parts maintain identical frequency stability, package footprint, and moisture sensitivity ratings. Selection between these parts should be based on specific operating temperature requirements and power consumption constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 7C-50.000MCB-T replace the FD5000040 in all applications?

A: The 7C-50.000MCB-T is functionally equivalent for applications operating within the -10°C to 70°C temperature range. Applications requiring operation below -10°C must use the FD5000040 due to its extended lower temperature specification.

Q: Are the package dimensions identical between these parts?

A: The footprint dimensions are identical at 5.00mm x 3.20mm. The seated height differs slightly: FD5000040 is 1.30mm maximum, while 7C-50.000MCB-T is 1.40mm maximum. This 0.10mm difference is negligible for most PCB designs but should be verified for applications with strict height constraints.

Q: What are the key electrical parameters that must match for substitution?

A: Frequency (50 MHz), output type (CMOS), supply voltage (2.5V), enable/disable function, and frequency stability (±50ppm) must remain constant. These parameters define the functional equivalence between the FD5000040 and 7C-50.000MCB-T.

Q: Are both parts RoHS compliant?

A: Yes. The FD5000040 is ROHS3 Compliant, and the 7C-50.000MCB-T is RoHS Compliant. Both meet environmental regulatory requirements.

Q: What is the difference in supply current between these oscillators?

A: The FD5000040 has a maximum supply current of 35mA, while the 7C-50.000MCB-T is rated at 30mA maximum. The TXC part offers 5mA lower consumption, which may be beneficial in power-sensitive applications.
