Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASEMPC-10.000MHZ-LR-T is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 10 MHz
• Output Type: CMOS
• Function: Enable/Disable
• Voltage Supply Range: 2.25V ~ 3.6V
• Package / Case: 6-SMD, No Lead
• Mounting Type: Surface Mount
• Base Resonator: MEMS

Allowable Variation Parameters:

• Frequency Stability: Substitute may have different tolerance (±50ppm acceptable for applications not requiring ±25ppm precision)
• Operating Temperature Range: Substitute may have extended range (-55°C ~ 125°C acceptable for applications operating within -40°C ~ 85°C)
• Current - Supply (Max): Must not exceed 35mA
• Current - Supply (Disable) (Max): Must not exceed 26mA

The ASEMPC-10.000MHZ-Z-T meets all mandatory matching parameters and operates within allowable variation limits for frequency stability and temperature range, qualifying it as a manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ASEMPC-10.000MHZ-LR-T and ASEMPC-10.000MHZ-Z-T are Active products manufactured by Abracon LLC with identical RoHS3 compliance and REACH status. Selection between these parts depends on application-specific requirements:

Select ASEMPC-10.000MHZ-LR-T when:

• Frequency stability of ±25ppm is required
• Operating temperature range is limited to -40°C ~ 85°C

Select ASEMPC-10.000MHZ-Z-T when:

• Frequency stability of ±50ppm is acceptable
• Extended operating temperature range of -55°C ~ 125°C is beneficial
• Higher inventory availability is a consideration (1287 units in stock versus 877 units)

Both parts share identical electrical supply characteristics, current consumption specifications, and physical package dimensions, ensuring direct PCB compatibility and identical circuit performance within their respective operating parameters.

Frequently Asked Questions (FAQ)

Q: Can ASEMPC-10.000MHZ-Z-T replace ASEMPC-10.000MHZ-LR-T in all applications?

A: Direct replacement is possible only when the application does not require ±25ppm frequency stability. The ASEMPC-10.000MHZ-Z-T operates at ±50ppm stability. If your circuit design specifies ±25ppm as a requirement, the substitute part does not meet that specification. Both parts are electrically and mechanically compatible for PCB assembly.

Q: What is the difference between these two oscillators?

A: The primary differences are frequency stability tolerance (±25ppm versus ±50ppm) and operating temperature range (-40°C ~ 85°C versus -55°C ~ 125°C). All other electrical and mechanical parameters are identical, including supply voltage, current consumption, output type, frequency, and package dimensions.

Q: Are both parts suitable for surface mount assembly?

A: Yes. Both the ASEMPC-10.000MHZ-LR-T and ASEMPC-10.000MHZ-Z-T use identical 6-SMD, No Lead surface mount packaging with dimensions of 3.20mm x 2.50mm and maximum seated height of 0.90mm. They are compatible with standard SMD assembly processes.

Q: Do these oscillators require any special handling?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements. Standard ESD precautions for surface mount components apply.

Q: Are both parts RoHS compliant?

A: Yes. Both ASEMPC-10.000MHZ-LR-T and ASEMPC-10.000MHZ-Z-T are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.
