Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the CSX-750F series are qualified based on the following critical parameters that determine functional interchangeability:

Mandatory Matching Parameters:

• Frequency: 16 MHz
• Output Type: CMOS
• Package / Case: 4-SMD, No Lead
• Mounting Type: Surface Mount
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Height - Seated (Max): 0.063" (1.60mm)
• Frequency Stability: ±50ppm
• Operating Temperature Range: -20°C ~ 70°C
• Function: Standby (Power Down)
• Series: CSX-750F
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Variable Parameters (Allowable Differences):

• Voltage - Supply: May differ (2.5V or 1.8V)
• Current - Supply (Max): May differ within operational limits
• Current - Supply (Disable) (Max): Consistent at 10µA

The CSX-750FMB16000000T qualifies as a substitute part because it maintains all mandatory matching parameters while operating at a different supply voltage (1.8V instead of 2.5V) with reduced maximum supply current (2.5mA instead of 3mA).

Parameter Comparison

Engineering Selection Recommendations

Both the CSX-750FHB16000000T and CSX-750FMB16000000T are Active status components manufactured by Citizen Finedevice Co Ltd within the CSX-750F series. Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, meeting regulatory and environmental requirements for industrial and consumer applications.

Selection between these parts depends on circuit supply voltage requirements. The CSX-750FHB16000000T operates at 2.5V supply voltage with 3mA maximum supply current. The CSX-750FMB16000000T operates at 1.8V supply voltage with 2.5mA maximum supply current, offering lower power consumption in 1.8V system designs.

Both parts share identical mechanical packaging (4-SMD, No Lead; 7.00mm x 5.00mm x 1.60mm), frequency specification (16 MHz), frequency stability (±50ppm), operating temperature range (-20°C ~ 70°C), and standby power-down functionality. Direct substitution is valid when circuit supply voltage compatibility is confirmed.

Frequently Asked Questions (FAQ)

Q: Can CSX-750FMB16000000T replace CSX-750FHB16000000T in existing designs?

A: Substitution is valid only if the circuit power supply operates at 1.8V. The CSX-750FMB16000000T requires 1.8V supply voltage, while the CSX-750FHB16000000T requires 2.5V. Voltage mismatch will result in oscillator malfunction. Verify circuit supply voltage before substitution.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use identical 4-SMD, No Lead packaging with dimensions of 0.276" L x 0.197" W (7.00mm x 5.00mm) and maximum seated height of 0.063" (1.60mm). PCB footprints and assembly processes are interchangeable.

Q: What is the frequency stability specification for both parts?

A: Both the CSX-750FHB16000000T and CSX-750FMB16000000T maintain ±50ppm frequency stability across the operating temperature range of -20°C ~ 70°C.

Q: Do both parts support standby power-down functionality?

A: Yes. Both parts include standby (power down) functionality with maximum disable current of 10µA, enabling low-power operation in battery-powered and energy-conscious applications.

Q: What are the RoHS and environmental compliance statuses?

A: Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Which part offers lower power consumption?

A: The CSX-750FMB16000000T operates at 1.8V with maximum supply current of 2.5mA, compared to the CSX-750FHB16000000T at 2.5V with maximum supply current of 3mA. The 1.8V variant provides reduced power consumption in compatible system designs.
