Key Parameters

Substitute Part Grouping Explanation

The ECS-65-12-7SX-TR qualifies as a parametric equivalent to the ECS-65-12-7S-TR based on the following critical parameters:

• Identical frequency: 6.5536 MHz
• Identical frequency tolerance: ±30ppm
• Identical load capacitance: 12pF
• Identical ESR: 100 Ohms
• Identical operating mode: Fundamental
• Identical package and pitch: 4-SOJ, 9.40mm
• Identical physical dimensions: 12.50mm x 4.60mm x 3.70mm (max height)
• Identical operating temperature range: -10°C ~ 70°C
• Identical MSL rating: 1 (Unlimited)

The primary distinction between these parts is product status and compliance certification. The ECS-65-12-7SX-TR is Active and RoHS3 Compliant, whereas the ECS-65-12-7S-TR is Not For New Designs and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The ECS-65-12-7SX-TR is the direct substitute for the ECS-65-12-7S-TR. All electrical and mechanical parameters are identical, ensuring pin-for-pin and functional compatibility in existing circuit designs.

Selection of the ECS-65-12-7SX-TR is supported by:

• Active product status, ensuring continued manufacturer support and availability
• RoHS3 compliance, meeting current environmental and regulatory requirements for new production
• Identical electrical specifications eliminating circuit redesign requirements
• Identical package geometry and mounting characteristics enabling direct PCB assembly compatibility

The ECS-65-12-7S-TR should be phased out in favor of the ECS-65-12-7SX-TR for new designs and production runs.

Frequently Asked Questions (FAQ)

Q: Can the ECS-65-12-7SX-TR be used as a direct replacement for the ECS-65-12-7S-TR?

A: Yes. The ECS-65-12-7SX-TR is electrically and mechanically identical to the ECS-65-12-7S-TR. All critical parameters including frequency, load capacitance, ESR, operating temperature range, and package dimensions are equivalent. No circuit modifications are required.

Q: What is the difference between these two parts?

A: The primary differences are product status and compliance certification. The ECS-65-12-7SX-TR is an Active product with RoHS3 compliance, while the ECS-65-12-7S-TR is Not For New Designs and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use the identical 4-SOJ package with 9.40mm pitch and identical physical dimensions (12.50mm x 4.60mm x 3.70mm max height). PCB footprints and assembly processes remain unchanged.

Q: Which part should be specified for new designs?

A: The ECS-65-12-7SX-TR should be specified for all new designs. The ECS-65-12-7S-TR is designated Not For New Designs and represents an obsolete product line.

Q: Are there any compliance differences that affect system certification?

A: The ECS-65-12-7SX-TR carries RoHS3 compliance certification, which is required for many regulatory frameworks and customer specifications. The ECS-65-12-7S-TR is RoHS non-compliant. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.
