Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-160-20-30B-AGL-TR is determined by the following critical parameters:

• Frequency: 16 MHz (exact match required)
• Load Capacitance: 20pF (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Size / Dimension: 5.00mm x 3.20mm (exact match required)
• Operating Mode: Fundamental (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling requirement)

Acceptable variations within substitution criteria include frequency stability tolerance, ESR specifications, and operating temperature ranges, provided the substitute part maintains compatibility with the circuit design parameters and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The FC5BQCCMC16.0-T1 from Fox Electronics qualifies as a direct substitute for the ECS-160-20-30B-AGL-TR based on matching frequency, load capacitance, package configuration, and regulatory compliance. Both components are active products with ROHS3 certification and MSL Level 1 rating.

Selection between these parts should account for the following differences:

• Frequency tolerance specification: The main part specifies ±25ppm tolerance, while the substitute specifies ±30ppm. Applications requiring tighter tolerance control may require circuit-level compensation or alternative sourcing.
• ESR variation: The substitute part exhibits 80 Ohms ESR compared to 50 Ohms in the main part. Circuit designs with ESR-sensitive oscillator configurations should evaluate this parameter against design specifications.
• Operating temperature lower limit: The main part operates from -10°C, while the substitute operates from 0°C. Applications requiring sub-zero temperature operation must use the ECS-160-20-30B-AGL-TR.
• Physical height: The substitute part has a maximum seated height of 1.20mm versus 0.85mm for the main part. PCB layout with height constraints should be verified.

Both parts maintain identical frequency stability (±30ppm), fundamental operating mode, and surface mount 4-SMD package configuration.

Frequently Asked Questions (FAQ)

Q: Can the FC5BQCCMC16.0-T1 be used as a direct replacement for the ECS-160-20-30B-AGL-TR?

A: The FC5BQCCMC16.0-T1 is compatible for applications where the operating temperature range does not extend below 0°C, frequency tolerance of ±30ppm is acceptable, and ESR of 80 Ohms is within circuit design parameters. Both parts share identical frequency, load capacitance, package type, and physical dimensions (5.00mm x 3.20mm).

Q: What are the key differences between these two 16 MHz crystals?

A: The primary differences are operating temperature range (-10°C to 70°C versus 0°C to 70°C), frequency tolerance specification (±25ppm versus ±30ppm), ESR (50 Ohms versus 80 Ohms), and maximum seated height (0.85mm versus 1.20mm). All other critical parameters including frequency, load capacitance, package configuration, and compliance certifications are identical.

Q: Does the higher ESR of the substitute part affect circuit performance?

A: ESR impact depends on the specific oscillator circuit design. The 30 Ohm difference (50 Ohms to 80 Ohms) may affect startup characteristics, power consumption, or frequency accuracy in designs with tight ESR specifications. Circuit validation is necessary to confirm compatibility.

Q: Are both parts RoHS compliant?

A: Yes, both the ECS-160-20-30B-AGL-TR and FC5BQCCMC16.0-T1 are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What should be considered when selecting between these parts?

A: Selection criteria include required operating temperature range, acceptable frequency tolerance, ESR requirements, available PCB height clearance, and inventory availability. Applications operating below 0°C must use the ECS part. Applications with tight frequency tolerance requirements should use the ECS part. All other applications may use either part based on availability and cost considerations.
