Key Parameters

Substitute Part Grouping Explanation

The ECS-160-S-7SX-TR qualifies as a substitute for the ECS-160-S-7S-TR based on the following matching parameters:

• Frequency: 16 MHz (identical)
• Frequency Tolerance: ±30ppm (identical)
• Operating Temperature Range: -10°C ~ 70°C (identical)
• Package / Case: 4-SOJ, 9.40mm pitch (identical)
• Mounting Type: Surface Mount (identical)
• Operating Mode: Fundamental (identical)
• Load Capacitance: Series (identical)

The primary difference between these parts is the ESR specification: the main part specifies 40 Ohms, while the substitute specifies 50 Ohms. This variance remains within acceptable substitution parameters for this crystal category.

Parameter Comparison

Engineering Selection Recommendations

The ECS-160-S-7S-TR is the preferred selection for new designs due to its Active product status and lower ESR specification of 40 Ohms. The ECS-160-S-7SX-TR is designated as Not For New Designs but remains available as a substitute where inventory or compliance requirements necessitate its use. The substitute part carries ROHS3 compliance, whereas the main part is RoHS non-compliant. Both parts share identical frequency, tolerance, temperature range, and package specifications, ensuring mechanical and electrical compatibility within the specified ESR variance of 10 Ohms.

Frequently Asked Questions (FAQ)

Q: Can ECS-160-S-7SX-TR replace ECS-160-S-7S-TR in existing designs?

A: Yes. Both parts operate at 16 MHz with ±30ppm tolerance, identical temperature range, and identical 4-SOJ package dimensions. The 10 Ohm ESR difference (40 Ohms vs. 50 Ohms) is the only electrical variance and remains within acceptable substitution parameters for this crystal category.

Q: What is the significance of the "Not For New Designs" status on the ECS-160-S-7SX-TR?

A: This designation indicates the part is in mature or declining production phase. While fully functional and available in inventory, ECS Inc. recommends the ECS-160-S-7S-TR for new product development. The substitute may be used for legacy system support or where specific compliance requirements apply.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.492" L x 0.181" W (12.50mm x 4.60mm) with a maximum seated height of 0.146" (3.70mm). They are mechanically interchangeable in 4-SOJ, 9.40mm pitch footprints.

Q: What is the difference in RoHS compliance between these parts?

A: The ECS-160-S-7S-TR is RoHS non-compliant, while the ECS-160-S-7SX-TR is ROHS3 compliant. Applications requiring RoHS3 certification must use the substitute part.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
