Substitute Part Grouping Explanation

Substitution eligibility for the ECS-60-S-7S-TR is determined by strict equivalence across the following critical parameters:

• Frequency: 6 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• ESR: 100 Ohms (exact match required)
• Load Capacitance: Series (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -10°C ~ 70°C (exact match required)
• Package / Case: 4-SOJ, 9.40mm pitch (exact match required)
• Physical Dimensions: 0.492" L x 0.181" W, 0.146" max height (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

The substitute part ECS-60-S-7SX-TR meets all electrical and mechanical parameters required for direct substitution. The primary distinction is the series designation (ECX-3SX versus ECX-3S) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The ECS-60-S-7SX-TR is a direct electrical and mechanical equivalent to the ECS-60-S-7S-TR. Both parts are classified as "Not For New Designs" and share identical electrical specifications and physical packaging.

The primary distinction is regulatory compliance: the ECS-60-S-7SX-TR is ROHS3 compliant, while the ECS-60-S-7S-TR is RoHS non-compliant. For applications subject to RoHS regulations or requiring compliance documentation, the ECS-60-S-7SX-TR is the appropriate selection. For legacy systems without RoHS requirements, either part is functionally equivalent.

Both parts carry REACH Unaffected status and EAR99 export classification. Current inventory availability is 1148 units for the ECS-60-S-7SX-TR and 3985 units for the ECS-60-S-7S-TR.

Frequently Asked Questions (FAQ)

Q: Can the ECS-60-S-7SX-TR be used as a direct replacement for the ECS-60-S-7S-TR?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including frequency, tolerance, ESR, operating temperature range, and package dimensions. No circuit modifications are required.

Q: What is the difference between these two parts?

A: The primary difference is RoHS compliance status. The ECS-60-S-7SX-TR is ROHS3 compliant, while the ECS-60-S-7S-TR is RoHS non-compliant. The series designation also differs (ECX-3SX versus ECX-3S). All electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with PCB assembly or soldering?

A: No. Both parts use the identical 4-SOJ package with 9.40mm pitch and identical physical dimensions. PCB footprints, reflow profiles, and assembly processes are interchangeable.

Q: Why are both parts marked "Not For New Designs"?

A: This designation indicates both parts have reached end-of-life status. They are available for existing production support and legacy system maintenance only. For new designs, consult the manufacturer for current-generation alternatives.

Q: Which part should be selected for RoHS-regulated applications?

A: The ECS-60-S-7SX-TR is ROHS3 compliant and is the appropriate choice for applications subject to RoHS directives or requiring compliance documentation.
