Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for 16 MHz crystal oscillators is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 16 MHz (exact match required)
• Frequency Tolerance: ±30ppm (determines circuit accuracy)
• Load Capacitance: 20pF (circuit-dependent specification)
• ESR: 40 Ohms (affects oscillation startup and stability)
• Package / Case: HC-49/US (physical and electrical interface)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Operating Mode: Fundamental (frequency generation method)

Flexible Parameters (within acceptable ranges):

• Frequency Stability: ±50ppm to ±100ppm (operational margin)
• Operating Temperature Range: -10°C ~ 70°C or -40°C ~ 85°C (application-dependent)
• Product Status: Active or Not For New Designs (availability consideration)
• RoHS Compliance: Compliant or non-compliant (regulatory requirement dependent)

Parameter Comparison

Engineering Selection Recommendations

ECS-160-20-4XDN is the preferred substitute for new applications and ongoing production. This part maintains identical electrical specifications to the main part (16 MHz, ±30ppm tolerance, 20pF load capacitance, 40 Ohms ESR) while offering Active product status and ROHS3 compliance. The identical operating temperature range (-40°C ~ 85°C) and frequency stability (±100ppm) ensure direct functional equivalence. Higher inventory availability (3760 Pcs) supports supply chain continuity.

ECS-160-20-4 is a compatible substitute for applications with relaxed temperature requirements. This part operates within -10°C ~ 70°C, which is narrower than the main part's -40°C ~ 85°C range. Frequency stability of ±50ppm is tighter than the main part's ±100ppm specification. This part maintains Not For New Designs status and RoHS non-compliance, matching the regulatory profile of the original part. Use this substitute only when operating temperature constraints align with application requirements.

Frequently Asked Questions (FAQ)

Q: Can ECS-160-20-4 replace ECS-160-20-4DN in all applications?

A: ECS-160-20-4 is electrically compatible for applications operating within -10°C ~ 70°C. If your application requires the full -40°C ~ 85°C temperature range, this substitute is not suitable. Verify your operating temperature requirements before selection.

Q: What is the primary advantage of ECS-160-20-4XDN?

A: ECS-160-20-4XDN maintains all electrical specifications of the main part while offering Active product status and ROHS3 compliance. This part is recommended for new designs and applications requiring regulatory compliance.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts use HC-49/US package with identical dimensions (0.447" L x 0.183" W, 11.35mm x 4.65mm) and through-hole mounting. Physical PCB layout compatibility is assured.

Q: Do frequency tolerance and frequency stability serve different purposes?

A: Yes. Frequency tolerance (±30ppm for all parts) specifies the initial accuracy at room temperature. Frequency stability (±50ppm to ±100ppm) specifies the maximum frequency variation across the operating temperature range and over time. Both parameters are critical for circuit design.

Q: Which substitute should I select for RoHS-compliant applications?

A: ECS-160-20-4XDN is ROHS3 compliant. Both ECS-160-20-4DN and ECS-160-20-4 are RoHS non-compliant. Select ECS-160-20-4XDN for applications requiring RoHS compliance.

Q: Can I use these parts interchangeably in existing designs?

A: All three parts share identical load capacitance (20pF) and ESR (40 Ohms), which are the primary circuit-dependent parameters. Substitution is valid provided operating temperature and compliance requirements are met.
