Substitute Part Grouping Explanation

Substitution eligibility for the ECS-160-S-1 is determined by strict alignment of the following critical parameters:

• Frequency: 16 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Mode: Fundamental (exact match required)
• Package / Case: HC-49/U (exact match required)
• Mounting Type: Through Hole (exact match required)
• Load Capacitance: Series (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

Substitute parts are grouped into two categories:

Parametric Equivalent: ECS-160-S-1X matches all critical electrical and mechanical parameters with the main part. Differences in series designation (HC-49UX vs HC-49U) and RoHS compliance status do not affect functional substitution.

Direct Manufacturer Alternative: MP160 (CTS-Frequency Controls) matches all critical parameters with allowable variations in ESR (25 Ohms vs 20 Ohms) and physical dimensions within the HC-49/U envelope, plus extended lower operating temperature (-20°C vs -10°C).

Parameter Comparison

Engineering Selection Recommendations

ECS-160-S-1X is the primary parametric equivalent, offering identical electrical specifications and mechanical fit. This substitute provides ROHS3 compliance where the original part does not, making it suitable for applications with regulatory compliance requirements. Both parts are manufactured by ECS Inc. and maintain identical frequency, tolerance, stability, and ESR characteristics.

MP160 (CTS-Frequency Controls) serves as a direct manufacturer alternative with matching frequency, tolerance, and stability parameters. The 5-ohm ESR increase (25 Ohms vs 20 Ohms) and extended lower operating temperature (-20°C vs -10°C) represent the primary differences. Physical dimensions are slightly reduced while maintaining HC-49/U package compatibility and maximum seated height. ROHS3 compliance is available with this substitute.

Selection between ECS-160-S-1X and MP160 depends on manufacturer preference, ESR requirements for specific circuit designs, and temperature range specifications. Both alternatives maintain full functional compatibility with applications designed for the ECS-160-S-1.

Frequently Asked Questions (FAQ)

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

A: Yes. ECS-160-S-1X matches all critical electrical parameters (frequency, tolerance, stability, ESR) and mechanical specifications (package, dimensions, mounting type). The primary difference is ROHS3 compliance status.

Q: What is the significance of the 5-ohm ESR difference between ECS-160-S-1 and MP160?

A: ESR affects circuit loading and power consumption. The MP160 at 25 Ohms versus the original 20 Ohms represents a 25% increase. Circuit designs must accommodate this difference in impedance characteristics.

Q: Are all three parts mechanically interchangeable in HC-49/U footprints?

A: Yes. All three parts use HC-49/U packaging with identical maximum seated height (0.530"). The MP160 has slightly reduced length and width dimensions but remains fully compatible with standard HC-49/U through-hole PCB layouts.

Q: Does the extended temperature range of MP160 (-20°C vs -10°C) affect compatibility?

A: No. The MP160's extended lower temperature range is a superset of the original specification. Applications operating within -10°C to 70°C will function identically with either part.

Q: Which substitute should be selected for RoHS-compliant designs?

A: Both ECS-160-S-1X and MP160 are ROHS3 compliant. The original ECS-160-S-1 is RoHS non-compliant. Select based on manufacturer preference and ESR requirements for your specific application.

Q: Are there any load capacitance differences between these parts?

A: No. All three parts specify series load capacitance, indicating identical circuit loading characteristics.
