Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-80-32-4X 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)
• 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 ~ 70°C (exact match required)

The ECS-80-32-4 meets all electrical and mechanical substitution criteria and is classified as a parametric equivalent.

Engineering Selection Recommendations

The ECS-80-32-4X is the preferred selection for new designs due to its Active product status and ROHS3 compliance. The ECS-80-32-4 is electrically and mechanically equivalent but carries Not For New Designs status and is RoHS non-compliant. Selection between these parts should be based on compliance requirements and design phase:

• For new designs requiring RoHS3 compliance: ECS-80-32-4X
• For legacy designs or applications where RoHS compliance is not required: ECS-80-32-4 may be considered as a functional equivalent

Both parts are identical in electrical performance, frequency characteristics, and physical dimensions.

Frequently Asked Questions (FAQ)

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

A: The ECS-80-32-4 is electrically and mechanically equivalent. However, it is marked Not For New Designs and is RoHS non-compliant, whereas the ECS-80-32-4X is Active and ROHS3 compliant. Substitution depends on your compliance requirements and design phase.

Q: What are the critical parameters that must match for substitution?

A: Frequency (8 MHz), frequency tolerance (±30ppm), load capacitance (32pF), ESR (80 Ohms), operating mode (Fundamental), package (HC-49/US), mounting type (Through Hole), and operating temperature range (-10°C ~ 70°C) must all match exactly.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical dimensions of 0.447" L x 0.183" W (11.35mm x 4.65mm) and maximum seated height of 0.138" (4.60mm).

Q: What is the difference between these two parts?

A: The primary differences are product status and RoHS compliance. The ECS-80-32-4X is Active and ROHS3 compliant, while the ECS-80-32-4 is Not For New Designs and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Which part should I specify for a new design?

A: Specify the ECS-80-32-4X for new designs to ensure compliance with current RoHS regulations and to use an Active product with ongoing manufacturer support.
