Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECS-80-32-1 is determined by strict equivalence across the following critical parameters:

• Frequency: 8 MHz (exact match required)
• Load Capacitance: 32pF (exact match required)
• ESR: 35 Ohms (exact match required)
• Package / Case: HC-49/U (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -10°C ~ 70°C (exact match required)
• Operating Mode: Fundamental (exact match required)

The ECS-80-32-1X meets all these criteria and qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications and mechanical dimensions, differing only in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The ECS-80-32-1X is the direct substitute for the ECS-80-32-1. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is product lifecycle status: the ECS-80-32-1 is marked Not For New Designs, while the ECS-80-32-1X carries Active status, indicating ongoing manufacturer support and availability.

For applications requiring RoHS3 compliance, the ECS-80-32-1X is the appropriate selection. The ECS-80-32-1 is RoHS non-compliant and should be reserved for legacy systems where compliance exemptions apply or where existing inventory must be utilized.

Both parts maintain identical operating temperature ranges, frequency specifications, and physical dimensions, ensuring direct interchangeability in HC-49/U through-hole crystal applications requiring 8 MHz fundamental mode operation with 32pF load capacitance.

Frequently Asked Questions (FAQ)

Q: Can the ECS-80-32-1X replace the ECS-80-32-1 in existing designs?

A: Yes. The ECS-80-32-1X is a parametric equivalent with identical electrical and mechanical specifications. Direct substitution is possible without circuit modification.

Q: What is the difference between these two parts?

A: The parts are electrically and mechanically identical. The ECS-80-32-1X is the current production version (Active status) with ROHS3 compliance, while the ECS-80-32-1 is a legacy part (Not For New Designs) that is RoHS non-compliant.

Q: Are the physical dimensions identical?

A: Yes. Both parts share the same HC-49/U package dimensions: 0.447" L x 0.183" W (11.35mm x 4.65mm) with maximum seated height of 0.530" (13.46mm).

Q: Do both parts operate at the same frequency and tolerance?

A: Yes. Both parts operate at 8 MHz with ±30ppm frequency tolerance and ±50ppm frequency stability, with 32pF load capacitance and 35 Ohms ESR.

Q: Which part should be selected for new designs?

A: The ECS-80-32-1X should be selected for new designs. It carries Active product status and ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.
