Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-110.5-32-4DN is determined by strict alignment of the following critical parameters:

Mandatory Match Parameters:

• Frequency: 11.0592 MHz (exact match required)
• Load Capacitance: 32 pF (exact match required)
• ESR: 60 Ohms (exact match required)
• Frequency Tolerance: ±30 ppm (substitute tolerance must be equal or tighter)
• Package / Case: HC-49/US (exact match required)
• Mounting Type: Through Hole (exact match required)

Operating Temperature Consideration: The substitute part must support the full operating temperature range of -40°C to 85°C specified for the main part, or the application must be re-evaluated for the substitute's narrower range.

The ECS-110.5-32-4 meets all mandatory electrical parameters and package requirements. However, its operating temperature range (-10°C ~ 70°C) is narrower than the main part, and its product status is classified as Not For New Designs, which affects long-term availability and supply chain planning.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: ECS-110.5-32-4DN

The ECS-110.5-32-4DN is the recommended choice for new designs and production applications. It carries Active product status, ensuring continued availability, supply chain stability, and manufacturer support. The operating temperature range of -40°C to 85°C accommodates industrial and extended commercial environments. Frequency stability of ±100 ppm provides adequate performance margin for standard timing applications.

Alternative Selection: ECS-110.5-32-4

The ECS-110.5-32-4 is electrically and mechanically compatible with the main part and may be used as a substitute only when the following conditions are met:

1. The application's operating temperature requirement does not exceed -10°C to 70°C
2. Long-term supply chain continuity is not a critical constraint
3. The product's Not For New Designs status is acceptable for the intended application lifecycle

Both parts share identical RoHS non-compliance and REACH Unaffected designations, indicating equivalent regulatory compliance profiles.

Frequently Asked Questions (FAQ)

Q: Can ECS-110.5-32-4 be used as a direct replacement for ECS-110.5-32-4DN on existing boards?

A: Electrical and mechanical compatibility is confirmed. However, the narrower operating temperature range (-10°C ~ 70°C versus -40°C ~ 85°C) must be evaluated against your application's environmental requirements. If your circuit operates within the substitute's temperature limits, direct substitution is feasible without circuit modification.

Q: What does "Not For New Designs" mean for the ECS-110.5-32-4?

A: This designation indicates the manufacturer is not recommending this part for new product development. It may have limited future availability or reduced manufacturer support. For new designs, the Active-status ECS-110.5-32-4DN is the preferred choice.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the HC-49/US package with identical dimensions (0.447" L x 0.183" W, 11.35mm x 4.65mm) and maximum seated height (0.138" / 4.60mm). They are mechanically interchangeable on through-hole PCBs.

Q: Do these crystals have different frequency tolerances?

A: No. Both parts specify ±30 ppm frequency tolerance. The ECS-110.5-32-4 has tighter frequency stability (±50 ppm versus ±100 ppm), which is a performance advantage but does not affect substitution eligibility.

Q: What is the significance of the "-DN" and "-4" suffixes in the part numbers?

A: The suffix designates internal manufacturing or packaging variants within the same electrical specification. The "-DN" suffix on the main part and the absence of this suffix on the substitute indicate different production batches or packaging configurations, but both deliver identical electrical performance for the specified parameters.

Q: Are there any compliance differences between these parts?

A: Both parts share identical RoHS non-compliance and REACH Unaffected status. No compliance advantage exists between the two options.
