Substitute Part Grouping Explanation

Substitution of the ECS-60-32-4 is determined by strict equivalence across the following critical parameters:

• Frequency: 6 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 32pF (exact match required)
• ESR: 100 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Package / Case: HC-49/US (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -10°C to 70°C (minimum required)

The ECS-60-32-4X meets all substitution criteria as a parametric equivalent manufactured by ECS Inc. in the same HC-49/US package with identical electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ECS-60-32-4X is the direct parametric equivalent for the ECS-60-32-4. Both parts share identical electrical and mechanical specifications across all critical parameters including frequency, load capacitance, ESR, package, and operating temperature range.

The primary distinction between these parts is product status and regulatory compliance. The ECS-60-32-4 carries "Not For New Designs" status and is RoHS non-compliant, while the ECS-60-32-4X is classified as Active and ROHS3 Compliant. For applications requiring RoHS compliance or long-term component availability, the ECS-60-32-4X is the appropriate selection.

Both parts maintain identical moisture sensitivity levels and REACH/ECCN classifications, ensuring equivalent handling and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the ECS-60-32-4X be used as a direct replacement for the ECS-60-32-4?

A: Yes. The ECS-60-32-4X is a parametric equivalent with identical frequency, load capacitance, ESR, operating mode, package type, and temperature range. Pin-to-pin and mechanical compatibility are confirmed.

Q: What is the difference between these two parts?

A: The ECS-60-32-4X is the active production equivalent. It differs in product status (Active vs. Not For New Designs) and RoHS compliance (ROHS3 Compliant vs. non-compliant). All electrical and mechanical parameters are identical.

Q: Are there any package or mounting differences?

A: No. Both parts use the HC-49/US through-hole package with identical dimensions (0.447" L x 0.183" W, 11.35mm x 4.65mm) and maximum seated height (0.138" / 4.60mm).

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and regulatory requirements, not electrical performance. Both parts meet the same frequency tolerance (±30ppm), load capacitance (32pF), and ESR (100 Ohms) specifications.

Q: Which part should be selected for new designs?

A: The ECS-60-32-4X should be selected for new designs due to its Active product status and ROHS3 compliance. The ECS-60-32-4 is designated "Not For New Designs."
