CSX-750FHB24000000T Equivalent & Substitute Parts

Part Overview

The CSX-750FHB24000000T is a 24 MHz XO (Standard) CMOS oscillator manufactured by Citizen Finedevice Co Ltd, designed for applications requiring a crystal-based frequency reference with standby power-down capability. This Active product operates at 2.5V supply voltage with a maximum supply current of 3mA and frequency stability of ±50ppm. The component is packaged in a 4-SMD, No Lead surface mount configuration with dimensions of 7.00mm x 5.00mm and a seated height of 1.60mm maximum. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across different supply voltage specifications within the same product series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the CSX-750F series is determined by the following critical parameters that must remain constant or compatible:

• Frequency: 24 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 7.00mm x 5.00mm (exact match required)
• Height - Seated (Max): 1.60mm (exact match required)
• Operating Temperature Range: -20°C ~ 70°C (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Function: Standby (Power Down) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The CSX-750FMB24000000T qualifies as a substitute part because it maintains all critical electrical and mechanical parameters. The primary difference is the supply voltage specification: CSX-750FMB24000000T operates at 1.8V with a maximum supply current of 2.5mA, compared to the 2.5V / 3mA specification of the main part. Both parts share identical frequency, output type, package configuration, physical dimensions, temperature range, frequency stability, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CSX-750FHB24000000T and CSX-750FMB24000000T are Active products with ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

Selection between these parts is determined by system supply voltage requirements. The CSX-750FHB24000000T is specified for 2.5V supply applications, while the CSX-750FMB24000000T is specified for 1.8V supply applications. The choice of substitute part must align with the actual supply voltage available in the target circuit. Both parts deliver identical frequency output (24 MHz), frequency stability (±50ppm), and mechanical compatibility within the same 4-SMD, No Lead package footprint.

Frequently Asked Questions (FAQ)

Q: Can CSX-750FMB24000000T replace CSX-750FHB24000000T in any application?

A: Substitution is valid only when the target circuit operates at 1.8V supply voltage. The CSX-750FMB24000000T is not suitable for circuits designed for 2.5V supply operation. Verify the actual supply voltage specification of your application before selecting a substitute part.

Q: Are the physical dimensions and package footprints identical?

A: Yes. Both parts use the 4-SMD, No Lead package with dimensions of 7.00mm x 5.00mm and a maximum seated height of 1.60mm. PCB layout and component placement are compatible between the two parts.

Q: Do both parts have the same frequency stability?

A: Yes. Both the CSX-750FHB24000000T and CSX-750FMB24000000T maintain ±50ppm frequency stability across the operating temperature range of -20°C to 70°C.

Q: What is the difference in power consumption between these parts?

A: The CSX-750FHB24000000T draws a maximum of 3mA during normal operation, while the CSX-750FMB24000000T draws a maximum of 2.5mA. Both parts draw 10µA maximum in disable mode. The lower current specification of the CSX-750FMB24000000T reflects its lower supply voltage operation.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component use in regulated markets.
