ECS-80-S-4 Crystal Equivalent & Substitute Parts

Part Overview

The ECS-80-S-4 is an 8 MHz through-hole crystal oscillator in HC-49/US package with 80 Ohms equivalent series resistance (ESR) and ±30ppm frequency tolerance. This component is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. For new applications or when the original part becomes unavailable, equivalent substitute parts meeting identical electrical and mechanical specifications are necessary to maintain circuit functionality and design compatibility.

Key Parameters

Substitute Part Grouping Explanation

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

• Frequency: 8 MHz (exact match required)
• Frequency Tolerance: ±30ppm (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 substitute part ECS-80-S-4X meets all these criteria and is therefore a direct parametric equivalent. The primary distinction between the main part and its substitute is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The ECS-80-S-4X is the direct substitute for the ECS-80-S-4. Both parts are electrically and mechanically identical across all specified parameters. The ECS-80-S-4X is preferred for new designs and applications requiring component replacement due to its Active product status and ROHS3 compliance certification. The original ECS-80-S-4 is designated "Not For New Designs" and carries RoHS non-compliant status, making it unsuitable for applications subject to RoHS3 regulatory requirements. Both parts share identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can ECS-80-S-4X be used as a direct replacement for ECS-80-S-4 in existing designs?

A: Yes. The ECS-80-S-4X is a direct parametric equivalent. All electrical specifications (frequency, tolerance, ESR, operating mode, temperature range) and mechanical specifications (package, dimensions, mounting type) are identical. No circuit modifications are required.

Q: What is the primary difference between ECS-80-S-4 and ECS-80-S-4X?

A: The ECS-80-S-4X has Active product status and ROHS3 compliance, while the ECS-80-S-4 is Not For New Designs and RoHS non-compliant. Electrically and mechanically, both parts are equivalent.

Q: Are there any compatibility concerns when substituting ECS-80-S-4 with ECS-80-S-4X?

A: No compatibility concerns exist. Both parts use the HC-49/US package with identical physical dimensions and mounting specifications. PCB footprints and circuit connections remain unchanged.

Q: Does the ECS-80-S-4X meet RoHS3 requirements?

A: Yes. The ECS-80-S-4X is ROHS3 compliant. The original ECS-80-S-4 is RoHS non-compliant.

Q: Are both parts subject to export control restrictions?

A: Both parts carry the same ECCN classification (EAR99) and HTSUS code (8541.60.0050), indicating identical export control treatment.
