Substitute Part Grouping Explanation

Substitution for the ECS-92.1-20-1 is determined by strict equivalence across the following critical parameters:

• Frequency: 9.216 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 20pF (exact match required)
• ESR: 35 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 substitute part ECS-92.1-20-1X meets all these criteria and is therefore a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ECS-92.1-20-1X is a direct parametric equivalent to the ECS-92.1-20-1 across all critical electrical and mechanical specifications. The primary distinction is RoHS compliance status: the ECS-92.1-20-1X is ROHS3 compliant, while the ECS-92.1-20-1 is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. Both parts maintain identical frequency, load capacitance, ESR, package dimensions, and operating temperature specifications. The ECS-92.1-20-1X offers higher inventory availability at 1307 pieces compared to 885 pieces for the original part.

Frequently Asked Questions (FAQ)

Q: Can ECS-92.1-20-1X be used as a direct replacement for ECS-92.1-20-1?

A: Yes. The ECS-92.1-20-1X is a parametric equivalent with identical frequency (9.216 MHz), load capacitance (20pF), ESR (35 Ohms), package (HC-49/U), and operating temperature range (-10°C ~ 70°C). Both parts are through-hole mounted and operate in fundamental mode.

Q: What is the difference between these two parts?

A: The primary difference is RoHS compliance. The ECS-92.1-20-1X is ROHS3 compliant, while the ECS-92.1-20-1 is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical?

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 0.530" (13.46mm).

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. If RoHS3 compliance is required, use ECS-92.1-20-1X. If RoHS compliance is not a requirement, either part is suitable based on availability and project specifications.

Q: Are there any frequency or tolerance differences?

A: No. Both parts have identical frequency tolerance of ±30ppm and frequency stability of ±50ppm.
