Substitute Part Grouping Explanation

Substitution eligibility for the ECS-480-S-1 is determined by strict equivalence across the following critical parameters:

• Frequency: 48 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• ESR: 40 Ohms (exact match required)
• Operating Mode: 3rd Overtone (exact match required)
• Package / Case: HC-49/U (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -10°C to 70°C (exact match required)
• Physical Dimensions: 0.447" L x 0.183" W, Height 0.530" max (exact match required)

The ECS-480-S-1X meets all substitution criteria as a parametric equivalent. The primary distinction is product status: ECS-480-S-1X is Active, whereas ECS-480-S-1 is Not For New Designs.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing production requiring a 48 MHz crystal with HC-49/U through-hole package, ESR of 40 Ohms, and ±30ppm tolerance, the ECS-480-S-1X is the appropriate selection. This part maintains full electrical and mechanical equivalence to the ECS-480-S-1 while offering Active product status and ROHS3 compliance, addressing regulatory requirements and long-term supply chain sustainability.

The ECS-480-S-1 remains suitable for legacy system maintenance and repair applications where existing inventory is available and RoHS compliance is not mandated.

Frequently Asked Questions (FAQ)

Q: Can ECS-480-S-1X be used as a direct replacement for ECS-480-S-1 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 48 MHz frequency, ±30ppm tolerance, 40 Ohms ESR, 3rd overtone operation, HC-49/U package, and through-hole mounting. Physical dimensions and operating temperature ranges are identical.

Q: What is the primary difference between these two parts?

A: Product status and compliance. ECS-480-S-1 is marked Not For New Designs and is RoHS non-compliant. ECS-480-S-1X is Active and ROHS3 compliant, making it the recommended choice for new applications.

Q: Are there any package or footprint differences?

A: No. Both parts use identical HC-49/U through-hole packages with matching physical dimensions: 0.447" L x 0.183" W and 0.530" maximum seated height.

Q: What frequency tolerance should be specified for circuit design?

A: Both parts guarantee ±30ppm frequency tolerance with ±50ppm stability. Design calculations should use ±30ppm as the maximum frequency deviation specification.

Q: Are these parts suitable for high-temperature applications?

A: Both parts operate within -10°C to 70°C. Applications requiring extended temperature ranges require alternative crystal specifications outside this series.
