• ESR: 50 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -10°C ~ 60°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Cylindrical Can, Radial (exact match required)
• Physical Dimensions: 0.126" Dia x 0.354" L (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

The substitute part ECS-160-18-9X meets all electrical and mechanical parameters specified above, establishing direct parametric equivalence.

Parameter Comparison

Engineering Selection Recommendations

The ECS-160-18-9X serves as a direct parametric equivalent to the ECS-160-18-9 across all electrical and mechanical specifications. Both parts are Active status products from the same manufacturer.

A key distinction exists in regulatory compliance: the ECS-160-18-9 is RoHS non-compliant, while the ECS-160-18-9X is ROHS3 compliant. Selection between these parts depends on application requirements and regulatory obligations. Applications subject to RoHS3 directives must use ECS-160-18-9X. Applications without RoHS3 requirements may use either part based on availability and supply chain considerations.

Both parts carry REACH Unaffected status and MSL Rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can ECS-160-18-9X replace ECS-160-18-9 in existing designs?

A: Yes. The ECS-160-18-9X is electrically and mechanically equivalent across all specified parameters: 16 MHz frequency, ±50ppm stability, 18pF load capacitance, 50 Ohms ESR, through-hole mounting, cylindrical can package, and identical physical dimensions. No circuit modifications are required.

Q: What is the difference between these two parts?

A: The primary difference is RoHS compliance status. ECS-160-18-9 is RoHS non-compliant; ECS-160-18-9X is ROHS3 compliant. All electrical and mechanical parameters are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use identical cylindrical can, radial through-hole packages with matching physical dimensions of 0.126" diameter by 0.354" length (3.20mm x 9.00mm).

Q: Do these parts have different operating temperature ranges?

A: No. Both parts operate across the identical temperature range of -10°C to 60°C.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, use ECS-160-18-9X. For applications without RoHS3 mandates, either part is suitable based on availability.

Q: Are moisture sensitivity considerations different between these parts?

A: No. Both parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity constraints during standard storage and handling conditions.
