Key Parameters

Substitute Part Grouping Explanation

Substitution for the NX2016AB-32MHZ ST2 is determined by the following critical parameters:

• Frequency: Must be 32 MHz (exact match required)
• Load Capacitance: Must be 8pF (exact match required)
• Package / Case: Must be 4-SMD, No Lead (mechanical compatibility)
• Physical Dimensions: Must be 0.079" L x 0.063" W (2.00mm x 1.60mm) (PCB footprint compatibility)
• Operating Mode: Must be Fundamental (circuit design requirement)

Frequency stability, ESR, and operating temperature range may vary within acceptable tolerances for equivalent substitution. Parts meeting these core criteria are functionally interchangeable in the NX2016AB-32MHZ ST2 application.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing status, addressing the obsolescence of the NX2016AB-32MHZ ST2.

8Y-32.000MAAV-T (TXC CORPORATION): This substitute maintains the same ESR specification (80 Ohms) as the original part. Frequency stability is ±30ppm, which is broader than the original ±20ppm specification. Operating temperature range is -20°C ~ 70°C, narrower than the original -30°C ~ 75°C. This part is RoHS Compliant and available in Tape & Reel packaging.

ECS-320-8-37CKM (ECS Inc.): This substitute offers superior frequency stability at ±10ppm, tighter than the original ±20ppm specification. ESR is 60 Ohms, lower than the original 80 Ohms specification. Operating temperature range is -20°C ~ 70°C, narrower than the original -30°C ~ 75°C. This part is ROHS3 Compliant with significantly higher inventory availability and Tape & Reel packaging.

Both substitutes meet the core mechanical and electrical requirements for direct replacement. Selection depends on application-specific requirements for frequency stability, ESR tolerance, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 8Y-32.000MAAV-T replace the NX2016AB-32MHZ ST2 directly?

A: Yes. Both parts share identical frequency (32 MHz), load capacitance (8pF), package type (4-SMD, No Lead), and physical dimensions (2.00mm x 1.60mm). The 8Y-32.000MAAV-T has broader frequency stability (±30ppm vs. ±20ppm) and narrower operating temperature range (-20°C ~ 70°C vs. -30°C ~ 75°C). Verify application requirements for these parameter differences before implementation.

Q: Can the ECS-320-8-37CKM replace the NX2016AB-32MHZ ST2 directly?

A: Yes. Both parts share identical frequency (32 MHz), load capacitance (8pF), package type (4-SMD, No Lead), and physical dimensions (2.00mm x 1.60mm). The ECS-320-8-37CKM has tighter frequency stability (±10ppm vs. ±20ppm) and lower ESR (60 Ohms vs. 80 Ohms). Operating temperature range is narrower (-20°C ~ 70°C vs. -30°C ~ 75°C). Verify application requirements for these parameter differences before implementation.

Q: What are the critical parameters for substitution?

A: Frequency (32 MHz), load capacitance (8pF), package type (4-SMD, No Lead), and physical dimensions (2.00mm x 1.60mm) must match exactly. These parameters determine mechanical fit and electrical compatibility in the circuit.

Q: Do the substitute parts have different height specifications?

A: Yes. The NX2016AB-32MHZ ST2 has a maximum seated height of 0.020" (0.50mm), while both substitutes have 0.022" (0.55mm). Verify PCB clearance and component placement constraints before substitution.

Q: Are the substitute parts RoHS compliant?

A: Yes. The 8Y-32.000MAAV-T is RoHS Compliant, and the ECS-320-8-37CKM is ROHS3 Compliant. Both meet current environmental compliance requirements.

Q: What is the difference in ESR between the parts?

A: The NX2016AB-32MHZ ST2 and 8Y-32.000MAAV-T both have 80 Ohms ESR. The ECS-320-8-37CKM has 60 Ohms ESR, which is lower. Lower ESR may improve circuit performance in some applications but verify compatibility with circuit design specifications.
