Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-480-10-37-RWM-TR is determined by the following critical parameters:

Frequency matching at 48 MHz with ±15ppm stability ensures circuit timing requirements are met. Operating mode (Fundamental) and temperature range (-20°C to 70°C) must remain constant. Surface mount configuration with 4-SMD, No Lead package is mandatory for PCB compatibility. ROHS3 compliance and EAR99 classification are required for regulatory alignment.

Load capacitance and ESR values define circuit integration characteristics. The LFXTAL069528 operates at 8pF load capacitance with 100 Ohms ESR, representing a valid substitute when circuit design accommodates these parameter variations within the same frequency and stability specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ECS-480-10-37-RWM-TR and LFXTAL069528 maintain Active product status with full ROHS3 compliance and EAR99 classification, ensuring regulatory alignment for current applications. The primary differentiation lies in load capacitance (10pF versus 8pF) and ESR (50 Ohms versus 100 Ohms). Circuit design must accommodate these electrical parameter variations. The LFXTAL069528 offers a smaller physical footprint (1.60mm x 1.20mm versus 2.00mm x 1.60mm) and lower seated height (0.45mm versus 0.55mm), providing layout advantages in space-constrained applications. Both components operate identically across the specified frequency, stability, temperature range, and fundamental mode requirements.

Frequently Asked Questions (FAQ)

Q: Can the LFXTAL069528 directly replace the ECS-480-10-37-RWM-TR without circuit modification?

A: Direct replacement requires circuit design verification. The load capacitance difference (8pF versus 10pF) and ESR increase (100 Ohms versus 50 Ohms) may affect oscillator startup characteristics and frequency accuracy. Circuit simulation or bench testing is necessary to confirm compatibility within your specific application parameters.

Q: What is the significance of the load capacitance difference between these parts?

A: Load capacitance determines the external capacitor values required for oscillator operation. The 10pF specification of the ECS-480-10-37-RWM-TR requires different external capacitor selection than the 8pF specification of the LFXTAL069528. Incorrect capacitor values will degrade frequency stability and may prevent oscillation.

Q: Are both parts suitable for the same PCB layout?

A: Both components use identical 4-SMD, No Lead packaging and surface mount configuration. However, the LFXTAL069528 has smaller physical dimensions (1.60mm x 1.20mm versus 2.00mm x 1.60mm) and lower height (0.45mm versus 0.55mm). PCB footprints must match the specific part selected. The smaller LFXTAL069528 may fit in tighter layouts but requires footprint verification.

Q: Do both parts meet the same environmental and compliance standards?

A: Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99. Both operate across -20°C to 70°C. The ECS-480-10-37-RWM-TR specifies MSL 1 (Unlimited), while the LFXTAL069528 lists MSL as Not Applicable. Both maintain equivalent regulatory status for standard industrial applications.

Q: What inventory considerations apply to these substitutes?

A: The ECS-480-10-37-RWM-TR has 1350 pieces in stock. The LFXTAL069528 has 4635 pieces in stock, providing greater availability. Selection may depend on project timeline and supply chain requirements alongside electrical compatibility.
