Engineering Selection Recommendations

The ECS-60-S-1X is the direct parametric equivalent for the ECS-60-S-1. All electrical and mechanical specifications are identical, ensuring pin-for-pin and form-factor compatibility in existing circuit designs.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The ECS-60-S-1 is designated "Not For New Designs," reflecting its end-of-life classification. The ECS-60-S-1X maintains active product status and carries ROHS3 compliance certification, whereas the original part is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

For applications requiring continued supply of 6 MHz HC-49/U through-hole crystals with 40 Ohms ESR and ±30ppm tolerance, the ECS-60-S-1X provides equivalent electrical performance with the advantage of active manufacturing support and improved environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can the ECS-60-S-1X be used as a direct replacement for the ECS-60-S-1 in existing designs?

A: Yes. The ECS-60-S-1X is a parametric equivalent with identical frequency, tolerance, stability, ESR, load capacitance, operating mode, package type, mounting configuration, and physical dimensions. No circuit modifications are required.

Q: What is the difference between the HC-49/U and HC-49UX series designations?

A: Both parts use the HC-49/U package standard. The series designation difference reflects manufacturing evolution; electrical and mechanical specifications remain equivalent.

Q: Does the RoHS3 compliance of the ECS-60-S-1X affect compatibility with designs originally specified for the RoHS non-compliant ECS-60-S-1?

A: No. RoHS compliance status does not alter electrical performance or mechanical fit. The ECS-60-S-1X is fully compatible with existing circuit designs.

Q: Are there any temperature range limitations when substituting the ECS-60-S-1X for the ECS-60-S-1?

A: No. Both parts operate across the identical temperature range of -10°C to 70°C with equivalent frequency stability specifications.

Q: What is the significance of the "Active" product status of the ECS-60-S-1X compared to "Not For New Designs" for the ECS-60-S-1?

A: Active status indicates the ECS-60-S-1X is in current production with ongoing manufacturer support. The ECS-60-S-1 has reached end-of-life. For applications requiring long-term supply continuity, the ECS-60-S-1X is the recommended choice.
