Substitute Part Grouping Explanation

Substitution for the ECS-80-32-4 is determined by strict equivalence across the following critical parameters:

• Frequency: 8 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 32pF (exact match required)
• ESR: 80 Ohms (exact match required)
• Package / Case: HC-49/US (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -10°C ~ 70°C (exact match required)

The ECS-80-32-4X meets all these criteria and is therefore a direct parametric equivalent. Both parts share identical electrical specifications and physical dimensions, ensuring pin-for-pin and functional compatibility in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The ECS-80-32-4X is the direct substitute for the ECS-80-32-4. All electrical and mechanical parameters are identical, ensuring functional compatibility in existing designs.

The primary distinction between these parts is product lifecycle status and compliance certification. The ECS-80-32-4 is marked Not For New Designs and is RoHS non-compliant, while the ECS-80-32-4X carries Active status and is ROHS3 Compliant. For applications requiring RoHS compliance or long-term supply assurance, the ECS-80-32-4X is the appropriate selection. For legacy system maintenance where the original part specification must be preserved, either part is electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the ECS-80-32-4X be used as a direct replacement for the ECS-80-32-4?

A: Yes. Both parts are identical in frequency (8 MHz), load capacitance (32pF), ESR (80 Ohms), package (HC-49/US), and operating temperature range (-10°C ~ 70°C). They are pin-for-pin and functionally compatible.

Q: What is the difference between these two parts?

A: The ECS-80-32-4X is the current production equivalent. It differs in product status (Active vs. Not For New Designs) and RoHS compliance (ROHS3 Compliant vs. non-compliant). Electrical and mechanical specifications are identical.

Q: Are there any PCB layout or circuit design changes required when substituting the ECS-80-32-4X for the ECS-80-32-4?

A: No. Both parts use the HC-49/US through-hole package with identical dimensions and pinout. No PCB modifications are required.

Q: Which part should I select for new designs?

A: The ECS-80-32-4X should be selected for new designs. It carries Active product status and meets current RoHS3 compliance requirements.

Q: Can I use these parts interchangeably in existing inventory?

A: Yes. From an electrical and mechanical standpoint, the parts are fully interchangeable. Verify your application's compliance requirements before selecting between the RoHS non-compliant and ROHS3 Compliant versions.
