Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LFSPXO024589 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 50 MHz
• Output: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±50ppm
• Operating Temperature: -40°C to 85°C
• Package/Case: 4-SMD, No Lead
• Mounting Type: Surface Mount
• Base Resonator: Crystal
• Oscillator Type: XO (Standard)

All four substitute parts meet these mandatory criteria. Variations in current supply specifications, physical dimensions within the 4-SMD No Lead package envelope, and packaging format (Tape & Reel versus Bulk) do not affect functional substitutability. These parameters are secondary considerations for component selection based on application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

LFSPXO009592REEL (IQD Frequency Products)

This substitute offers the lowest maximum supply current at 6mA, providing superior power efficiency compared to the primary part. Both devices are manufactured by IQD Frequency Products and maintain ROHS3 compliance. The CFPS-69 series exhibits reduced physical height (0.95mm versus 1.30mm), which may be advantageous for space-constrained applications. Tape & Reel packaging is maintained for automated assembly compatibility.

7C-50.000MBE-T (TXC CORPORATION)

This TXC Corporation alternative maintains identical electrical specifications and maximum supply current (30mA) to the primary part. RoHS compliance is confirmed. Physical dimensions are slightly reduced (5.00mm x 3.20mm versus 5.20mm x 3.40mm), with increased seated height (1.40mm). Tape & Reel packaging supports production automation.

AC-50.000MBE-T (TXC CORPORATION)

This substitute is qualified to AEC-Q100 automotive standard, providing additional reliability certification beyond the primary part. Maximum supply current is 20mA, representing a moderate reduction from the LFSPXO024589. ROHS3 compliance is confirmed. Physical dimensions match the 7C series (5.00mm x 3.20mm). Tape & Reel packaging is provided.

SXO53C3A481-50.000M (Suntsu Electronics, Inc.)

This Suntsu alternative maintains maximum supply current at 25mA, positioned between the primary part and other substitutes. ROHS3 compliance is confirmed. Physical dimensions are identical to the TXC offerings (5.00mm x 3.20mm). Bulk packaging format requires manual handling or reel conversion for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can LFSPXO009592REEL be used as a direct replacement for LFSPXO024589?

A: Yes. Both parts share identical electrical specifications: 50 MHz frequency, CMOS output, 3.3V supply, enable/disable function, ±50ppm stability, and -40°C to 85°C operating range. The LFSPXO009592REEL operates at lower maximum current (6mA versus 30mA) and exhibits reduced physical height (0.95mm versus 1.30mm), making it functionally compatible for all applications where the primary part is specified.

Q: What are the physical dimension differences between substitute parts?

A: The LFSPXO024589 measures 5.20mm x 3.40mm with 1.30mm seated height. The LFSPXO009592REEL maintains the 5.20mm length but reduces width to 3.20mm and height to 0.95mm. The TXC (7C and AC series) and Suntsu parts all measure 5.00mm x 3.20mm with 1.40mm seated height. These variations remain within the 4-SMD No Lead package classification and do not affect PCB footprint compatibility.

Q: Does packaging format affect substitutability?

A: Packaging format (Tape & Reel versus Bulk) does not affect electrical or mechanical substitutability. The format selection depends on production requirements. Tape & Reel packaging (LFSPXO024589, LFSPXO009592REEL, 7C-50.000MBE-T, AC-50.000MBE-T) supports automated assembly. Bulk packaging (SXO53C3A481-50.000M) requires manual handling or conversion to reel format for automated processes.

Q: Are all substitute parts RoHS compliant?

A: Yes. LFSPXO024589, LFSPXO009592REEL, AC-50.000MBE-T, and SXO53C3A481-50.000M are ROHS3 compliant. The 7C-50.000MBE-T is RoHS compliant. All parts meet environmental compliance requirements for restricted substance elimination.

Q: What is the significance of the AEC-Q100 rating on AC-50.000MBE-T?

A: AEC-Q100 is an automotive industry qualification standard. The AC-50.000MBE-T carries this certification, indicating additional reliability testing and quality assurance beyond standard commercial specifications. This certification is relevant for automotive and high-reliability applications but does not affect functional compatibility with the primary part.

Q: How does supply current variation affect component selection?

A: Maximum supply current ranges from 6mA (LFSPXO009592REEL) to 30mA (LFSPXO024589 and 7C-50.000MBE-T). Lower current consumption reduces power dissipation and thermal load. Selection should be based on circuit power budget requirements. All parts operate within the 3.3V supply specification and maintain identical frequency and output characteristics.
