Substitute Part Grouping Explanation

Substitution for the ECS-160-20-1 is determined by exact matching of the following critical parameters:

  • Frequency: 16 MHz
  • Frequency Tolerance: ±30ppm
  • Load Capacitance: 20pF
  • ESR: 20 Ohms
  • Package / Case: HC-49/U
  • Mounting Type: Through Hole
  • Operating Temperature Range: -10°C ~ 70°C
  • Operating Mode: Fundamental

Parts meeting all these specifications are classified as parametric equivalents and direct substitutes. The ECS-160-20-1X meets all specified parameters and is therefore a valid substitute for the ECS-160-20-1.

Engineering Selection Recommendations

The ECS-160-20-1X is a direct parametric equivalent to the ECS-160-20-1. Both parts share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: the ECS-160-20-1 is marked Not For New Designs, while the ECS-160-20-1X carries Active status. Additionally, the ECS-160-20-1X is ROHS3 Compliant, whereas the ECS-160-20-1 is RoHS non-compliant. For applications requiring ongoing component availability and regulatory compliance, the ECS-160-20-1X is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the ECS-160-20-1X be used as a direct replacement for the ECS-160-20-1?

A: Yes. Both parts are identical in frequency (16 MHz), frequency tolerance (±30ppm), load capacitance (20pF), ESR (20 Ohms), package (HC-49/U), and operating temperature range (-10°C ~ 70°C). They are mechanically and electrically interchangeable.

Q: What is the difference between these two parts?

A: The ECS-160-20-1X is the active production equivalent. It differs in product status (Active vs. Not For New Designs) and RoHS compliance (ROHS3 Compliant vs. non-compliant). All functional parameters are identical.

Q: Are there any package or mounting differences?

A: No. Both parts use the HC-49/U through-hole package with identical dimensions (0.447" L x 0.183" W, 11.35mm x 4.65mm) and maximum seated height (0.530", 13.46mm).

Q: Which part should be selected for new designs?

A: The ECS-160-20-1X should be selected for new designs, as it carries Active product status and meets current RoHS3 compliance requirements.
