Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-32-17-1 is determined by strict equivalence across the following critical parameters:

• Frequency: 3.2768 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 17pF (exact match required)
• ESR: 120 Ohms (exact match required)
• Operating Mode: Fundamental (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)

The ECS-32-17-1X meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The ECS-32-17-1X is the direct parametric equivalent for the ECS-32-17-1. All electrical and mechanical specifications are identical. The primary distinction is product lifecycle status: the ECS-32-17-1 is classified as Not For New Designs, while the ECS-32-17-1X maintains Active status with current manufacturing support.

For applications requiring RoHS compliance, the ECS-32-17-1X is ROHS3 compliant, whereas the original ECS-32-17-1 is RoHS non-compliant. Both parts share identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the ECS-32-17-1X be used as a direct replacement for the ECS-32-17-1?

A: Yes. The ECS-32-17-1X is a parametric equivalent with identical frequency, load capacitance, ESR, package, and operating temperature specifications. Direct substitution is supported at the circuit level.

Q: What is the difference between these two part numbers?

A: The ECS-32-17-1X represents an updated version within the same product family (HC-49UX series versus HC-49U series). The substitute maintains Active product status and ROHS3 compliance, whereas the original is Not For New Designs and RoHS non-compliant.

Q: Are there any compatibility concerns with PCB footprints?

A: No. Both parts use identical HC-49/U packaging with matching dimensions (0.447" L x 0.183" W, 0.530" max seated height) and through-hole mounting. PCB footprints are interchangeable.

Q: Does the ECS-32-17-1X meet modern regulatory requirements?

A: The ECS-32-17-1X is ROHS3 compliant and REACH unaffected. The original ECS-32-17-1 is RoHS non-compliant. For applications subject to RoHS regulations, the substitute is the appropriate choice.

Q: Are the electrical characteristics identical?

A: Yes. Both parts specify 3.2768 MHz frequency with ±30ppm tolerance, 17pF load capacitance, 120 Ohms ESR, fundamental operating mode, and -10°C to 70°C operating temperature range.
