Substitute Part Grouping Explanation

The ASFLMB-10.000MHZ-LY-T is identified as a direct substitute for the ASFLMB-10.000MHZ-LC-T based on the following criteria:

Electrical Compatibility:

• Identical frequency: 10 MHz
• Identical output type: LVCMOS
• Identical supply voltage range: 1.8V ~ 3.3V
• Identical operating temperature range: -40°C ~ 85°C
• Identical current specifications: 16mA (Max) and 15µA (Disable)
• Identical base resonator technology: MEMS

Mechanical Compatibility:

• Identical package type: 4-SMD, No Lead
• Identical physical dimensions: 5.00mm x 3.20mm x 0.90mm (Max)
• Identical mounting type: Surface Mount

Regulatory & Compliance:

• Both RoHS3 compliant
• Both REACH unaffected
• Both classified as Active product status

Differentiation: The primary difference between these parts is packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) and frequency stability specification (±50ppm vs. ±10ppm). The substitute part offers improved frequency stability while maintaining all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the ASFLMB-10.000MHZ-LC-T and ASFLMB-10.000MHZ-LY-T are Active product status components from Abracon LLC, ensuring ongoing manufacturer support and availability. Both parts maintain identical electrical performance characteristics, supply voltage compatibility, and operating temperature specifications required for 10 MHz LVCMOS oscillator applications.

The ASFLMB-10.000MHZ-LY-T provides improved frequency stability at ±10ppm compared to the ±50ppm specification of the ASFLMB-10.000MHZ-LC-T. This enhanced stability may be beneficial for applications with stringent timing requirements. The packaging format difference (Cut Tape & Digi-Reel vs. Tape & Reel) reflects distribution and procurement preferences rather than functional capability.

Both parts satisfy RoHS3 compliance requirements and maintain MSL 1 moisture sensitivity classification, supporting standard PCB assembly and storage protocols. Selection between these parts should be based on packaging format availability, frequency stability requirements, and procurement specifications.

Frequently Asked Questions (FAQ)

Q: Can the ASFLMB-10.000MHZ-LY-T directly replace the ASFLMB-10.000MHZ-LC-T on a PCB?

A: Yes. Both parts share identical electrical specifications, output type (LVCMOS), supply voltage range (1.8V ~ 3.3V), operating temperature range (-40°C ~ 85°C), and physical dimensions (5.00mm x 3.20mm x 0.90mm Max). The 4-SMD, No Lead package footprint is identical, enabling direct PCB substitution without layout modifications.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format and frequency stability. The ASFLMB-10.000MHZ-LC-T uses Tape & Reel packaging with ±50ppm frequency stability, while the ASFLMB-10.000MHZ-LY-T uses Cut Tape & Digi-Reel packaging with improved ±10ppm frequency stability. All other electrical and mechanical parameters remain identical.

Q: Does the improved frequency stability of the ASFLMB-10.000MHZ-LY-T affect circuit design?

A: No. The improved ±10ppm stability of the ASFLMB-10.000MHZ-LY-T is a performance enhancement that does not require circuit design changes. Applications designed for the ±50ppm specification will operate within acceptable parameters with the improved stability part.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ASFLMB-10.000MHZ-LC-T and ASFLMB-10.000MHZ-LY-T are RoHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 classification indicates the component has unlimited shelf life under standard storage conditions (23°C ± 2°C, 50% ± 5% relative humidity). This eliminates moisture bake-out requirements prior to PCB assembly and simplifies inventory management.

Q: Can these parts be used interchangeably in high-frequency timing applications?

A: Yes, with consideration for frequency stability requirements. Both parts operate at 10 MHz with identical output characteristics. The ASFLMB-10.000MHZ-LY-T with ±10ppm stability is suitable for applications requiring tighter frequency tolerance, while the ASFLMB-10.000MHZ-LC-T with ±50ppm stability serves general-purpose timing applications.
