Package / Case: 4-SMD, No Lead (exact match required)

Secondary Compatibility Parameters:

Load Capacitance: 9pF (primary specification; 8pF to 10pF acceptable within circuit design tolerance)
ESR (Equivalent Series Resistance): 200 Ohms (primary specification; 100 to 150 Ohms acceptable with circuit validation)

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and full compliance with RoHS and REACH regulations. Selection among equivalent parts is based on the following engineering considerations:

ECS-160-9-37-CKM-TR (ECS Inc.): Provides exact load capacitance match (9pF) with reduced ESR (100 Ohms). Identical physical dimensions (2.00 x 1.60 mm) ensure direct PCB layout compatibility. ROHS3 compliance and Tape & Reel packaging support high-volume manufacturing processes.

8Z-16.000MEEQ-T (TXC CORPORATION): Maintains manufacturer continuity with same-source alternative. Load capacitance increased to 10pF with ESR reduced to 100 Ohms. Larger physical footprint (2.50 x 2.00 mm) requires PCB layout verification. Tape & Reel packaging supports automated assembly.

Q 16,0-JXS21-8-10/10-WA-LF (Jauch Quartz): Offers lowest load capacitance (8pF) with moderate ESR (120 Ohms). Identical physical dimensions (2.00 x 1.60 mm) maintain PCB compatibility. ROHS3 compliance and Tape & Reel packaging support production environments.

XYCBBCNANF-16.000000 (Taitien): Provides 10pF load capacitance with 150 Ohms ESR. Slightly larger physical dimensions (2.55 x 2.05 mm) require PCB layout verification. Cut Tape packaging suitable for lower-volume or mixed-component applications.

Frequently Asked Questions (FAQ)

Q: Can the 8Y-16.000MEEC-T be directly replaced with any of these substitute parts?

A: Direct replacement is possible when the circuit design accommodates the specified load capacitance and ESR values. ECS-160-9-37-CKM-TR and Q 16,0-JXS21-8-10/10-WA-LF maintain identical physical dimensions (2.00 x 1.60 mm) and require no PCB layout modifications. The 8Z-16.000MEEQ-T and XYCBBCNANF-16.000000 have larger footprints and require PCB layout verification before implementation.

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

A: Load capacitance affects the crystal's operating frequency within the specified tolerance band. The 8Y-16.000MEEC-T specifies 9pF; substitute parts range from 8pF to 10pF. All parts maintain ±10ppm frequency stability within their respective load capacitance specifications. Circuit design must account for the load capacitance of the selected crystal to ensure frequency accuracy.

Q: How does ESR (Equivalent Series Resistance) affect part selection?

A: ESR influences crystal startup characteristics and power consumption. The main part specifies 200 Ohms; substitutes range from 100 to 150 Ohms. Lower ESR values reduce startup time and power draw. All specified ESR values are within acceptable ranges for 16 MHz fundamental mode crystal applications.

Q: Are there packaging differences between substitute parts?

A: Yes. The main part uses standard packaging (not specified). Substitute parts are supplied in Tape & Reel (TR) or Cut Tape (CT) formats. Tape & Reel packaging supports high-speed automated assembly. Cut Tape packaging is suitable for lower-volume or mixed-component pick-and-place operations. Physical dimensions vary: 2.00 x 1.60 mm (main, ECS, Jauch), 2.50 x 2.00 mm (TXC 8Z series), and 2.55 x 2.05 mm (Taitien).

Q: Do all substitute parts meet the same compliance standards?

A: All parts are RoHS compliant and REACH unaffected. The main part specifies RoHS Compliant status; substitute parts specify ROHS3 Compliant status, which represents an updated compliance standard. All parts maintain MSL 1 (Unlimited) moisture sensitivity level and are suitable for standard manufacturing environments.

Q: What is the inventory availability for each part?

A: The 8Y-16.000MEEC-T has 807 pieces in stock. Substitute parts have higher availability: 8Z-16.000MEEQ-T (16,757 pieces), ECS-160-9-37-CKM-TR (22,848 pieces), Q 16,0-JXS21-8-10/10-WA-LF (2,847 pieces), and XYCBBCNANF-16.000000 (3,948 pieces). Higher inventory levels support extended production runs and reduce supply chain risk.
