Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FC4STCBAF16.0 is determined by strict alignment of the following parameters:

• Frequency: 16 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• ESR: 40 Ohms (exact match required)
• Package / Case: HC-49/US (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Mode: Fundamental (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)

The ECS-160-S-4X meets all substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The ECS-160-S-4X is a direct equivalent substitute for the FC4STCBAF16.0. Both components share identical electrical specifications (16 MHz frequency, ±30ppm tolerance, 40 Ohms ESR) and mechanical packaging (HC-49/US through-hole). Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

The operating temperature range of the ECS-160-S-4X (-10°C ~ 70°C) is narrower than the FC4STCBAF16.0 (-20°C ~ 70°C). Component selection should account for application-specific temperature requirements. The seated height difference (4.60mm versus 3.60mm) is within standard PCB layout tolerances for through-hole crystal packages.

Frequently Asked Questions (FAQ)

Q: Can the ECS-160-S-4X replace the FC4STCBAF16.0 in existing designs?

A: Yes. Both components meet identical electrical and mechanical specifications for 16 MHz fundamental mode operation in HC-49/US packaging. Direct PCB substitution is supported without circuit modification.

Q: What is the significance of the operating temperature range difference?

A: The FC4STCBAF16.0 operates from -20°C to 70°C, while the ECS-160-S-4X operates from -10°C to 70°C. Applications requiring operation below -10°C must use the FC4STCBAF16.0. For applications within the -10°C to 70°C range, both parts are functionally equivalent.

Q: Are there any package compatibility concerns?

A: No. Both components use identical HC-49/US through-hole packaging with matching footprints (0.447" L x 0.183" W). The 0.1mm seated height difference is negligible for standard PCB assembly processes.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the FC4STCBAF16.0 and ECS-160-S-4X are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8541.60.0050).

Q: What parameters must match exactly for substitution?

A: Frequency (16 MHz), frequency tolerance (±30ppm), ESR (40 Ohms), operating mode (Fundamental), package type (HC-49/US), and mounting method (Through Hole) must all match exactly. These parameters define functional equivalence for crystal oscillator substitution.
