Key Parameters

Substitute Part Grouping Explanation

Substitution of the SNSAS2150 is determined by the following critical parameters:

• Frequency Match: 150 MHz (exact match required)
• Output Logic Level: PECL or LVPECL (compatible logic families for this application)
• Supply Voltage: 3.3V (exact match required)
• Enable/Disable Function: Required functionality
• Package Type: 6-SMD, No Lead (mechanical compatibility)
• Package Dimensions: 7.00mm x 5.00mm (PCB layout compatibility)
• Frequency Stability: ±50ppm (performance specification)
• Operating Temperature Range: -20°C ~ 70°C (environmental specification)

The NX7021C0150.000000 qualifies as a substitute part because it matches all critical parameters while offering an Active product status and improved compliance certifications.

Engineering Selection Recommendations

The NX7021C0150.000000 is the recommended substitute for the obsolete SNSAS2150 based on the following engineering criteria:

Product Status: The NX7021C0150.000000 carries Active product status, ensuring continued availability and manufacturer support, whereas the SNSAS2150 is Obsolete.

Compliance Certifications: Both parts maintain REACH Unaffected status. The NX7021C0150.000000 provides ROHS3 Compliant certification, representing current regulatory compliance standards.

Electrical Compatibility: Both oscillators operate at identical frequency (150 MHz), supply voltage (3.3V), frequency stability (±50ppm), and temperature range (-20°C ~ 70°C). The output logic transition from PECL to LVPECL represents a compatible upgrade within the same logic family hierarchy.

Mechanical Compatibility: Identical package type (6-SMD, No Lead) and footprint dimensions (7.00mm x 5.00mm) ensure direct PCB layout compatibility without redesign.

Physical Characteristics: The NX7021C0150.000000 exhibits a lower seated height (1.55mm versus 2.00mm), which may provide advantages in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the NX7021C0150.000000 directly replace the SNSAS2150 without circuit modifications?

A: Yes. Both parts share identical frequency, supply voltage, enable/disable function, package type, and footprint dimensions. The output logic transition from PECL to LVPECL is compatible within the same signal family. No circuit modifications are required for substitution.

Q: What is the difference between PECL and LVPECL output?

A: LVPECL (Low Voltage PECL) is a compatible variant of PECL logic that operates at reduced voltage levels while maintaining signal integrity and compatibility with PECL receivers. Both are part of the same logic family hierarchy.

Q: Are there any current consumption differences between these parts?

A: The NX7021C0150.000000 has a maximum supply current of 80mA compared to 70mA for the SNSAS2150, and a maximum disable current of 40mA compared to 25mA. These differences are within typical design margins for 3.3V oscillator applications.

Q: Does the lower seated height of the NX7021C0150.000000 affect compatibility?

A: No. The lower height (1.55mm versus 2.00mm) is a physical advantage that improves clearance in space-constrained designs. It does not affect electrical compatibility or PCB layout.

Q: What certifications apply to both parts?

A: Both parts are REACH Unaffected and RoHS compliant. The NX7021C0150.000000 carries ROHS3 Compliant certification, representing current regulatory standards.

Q: Why is the SNSAS2150 marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The NX7021C0150.000000 represents the active equivalent within the same product family.
