Substitute Part Grouping Explanation

Substitution for the WX5011C0125.000000 is determined by strict alignment of the following electrical and mechanical parameters:

Frequency: 125 MHz (exact match required)
Output Type: CMOS or compatible logic family (HCMOS, LVCMOS acceptable)
Supply Voltage: 3.3V (exact match required)
Function: Enable/Disable capability (required)
Package Type: 4-SMD, No Lead (exact match required)
Package Dimensions: 5.00mm x 3.20mm (exact match required)
Operating Temperature Range: -20°C ~ 70°C (minimum required)
Frequency Stability: ±50ppm or better (tighter tolerance acceptable)

All identified substitute parts meet these core criteria. Variations in maximum supply current, disabled state current, and seated height are within acceptable engineering tolerances for this component category.

Engineering Selection Recommendations

All three substitute parts are Active products with current manufacturing status, providing long-term availability compared to the Obsolete WX5011C0125.000000.

NX5AC50001 (Diodes Incorporated): Maintains manufacturer continuity within the Diodes Incorporated product line. Offers improved frequency stability at ±25ppm and reduced maximum supply current of 60mA. Output type is HCMOS/LVCMOS, which is compatible with CMOS logic systems. ROHS3 compliant.

CPPLC5L-A5BP-125.0TS (Cardinal Components Inc.): Provides the lowest maximum supply current at 25mA, beneficial for power-constrained applications. Maintains exact CMOS output type and ±50ppm frequency stability matching the original part. Offers the lowest seated height at 1.30mm. Supplied in Tape & Reel packaging. ROHS3 compliant.

SXO53C3A271-125.000M (Suntsu Electronics, Inc.): Maintains exact electrical specifications including CMOS output and ±50ppm frequency stability. Highest inventory availability at 1691 pieces. Maximum supply current of 50mA is intermediate between alternatives. ROHS3 compliant.

All substitute parts meet the core electrical and mechanical requirements for direct substitution in applications requiring 125 MHz CMOS oscillators with 3.3V supply and Enable/Disable functionality.

Frequently Asked Questions (FAQ)

Q: Can NX5AC50001 replace WX5011C0125.000000 despite different output types (HCMOS/LVCMOS vs. CMOS)?

A: Yes. HCMOS and LVCMOS are compatible logic families with CMOS systems. The NX5AC50001 output is backward compatible with CMOS input requirements at 3.3V supply voltage.

Q: What is the significance of frequency stability differences (±25ppm vs. ±50ppm)?

A: Tighter frequency stability (±25ppm in NX5AC50001) provides better frequency accuracy over temperature and time. Applications with strict frequency tolerance requirements benefit from the NX5AC50001. Applications tolerant of ±50ppm can use any of the three substitutes.

Q: Are all substitute parts pin-compatible with the original WX5011C0125.000000?

A: Yes. All substitute parts use identical 4-SMD, No Lead package with 5.00mm x 3.20mm footprint and Enable/Disable functionality, ensuring PCB layout compatibility.

Q: Does the height variation (1.30mm to 1.40mm) affect PCB assembly?

A: No. All parts remain within acceptable surface mount assembly tolerances. Height variations of ±0.10mm are standard in this component category and do not impact reflow soldering or component clearance in typical PCB designs.

Q: Which substitute offers the best power efficiency?

A: CPPLC5L-A5BP-125.0TS provides the lowest maximum supply current at 25mA, making it optimal for battery-powered or power-constrained applications.

Q: Are all substitutes RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements.
