Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASDAIG3-27.000MHZ-X-K-T is determined by strict equivalence across the following critical parameters:

• Frequency: 27 MHz (exact match required)
• Output Configuration: HCMOS (exact match required)
• Supply Voltage: 1.8V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Package Dimensions: 0.098" L x 0.079" W / 2.50mm x 2.00mm (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Compliance: AEC-Q200 and ROHS3 Compliant (exact match required)

The ECS-2520Q-18-270-DP-TR meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ASDAIG3-27.000MHZ-X-K-T and ECS-2520Q-18-270-DP-TR are active production parts with identical AEC-Q200 automotive-grade qualification and ROHS3 compliance. The ECS-2520Q-18-270-DP-TR offers a marginal advantage in maximum supply current (3mA versus 4mA) and seated height (0.90mm versus 0.95mm), which may provide benefits in power-constrained or height-limited applications. Both parts are suitable for direct substitution in 27 MHz HCMOS oscillator applications requiring 1.8V operation with enable/disable control.

Frequently Asked Questions (FAQ)

Q: Can the ECS-2520Q-18-270-DP-TR replace the ASDAIG3-27.000MHZ-X-K-T in existing designs?

A: Yes. Both parts share identical electrical specifications (27 MHz, HCMOS output, 1.8V supply, ±30ppm stability, -40°C ~ 105°C operating range), identical package type (4-SMD, No Lead), identical package dimensions (2.50mm x 2.00mm), and identical compliance ratings (AEC-Q200, ROHS3). Pin-to-pin compatibility is maintained.

Q: What are the differences between these two oscillators?

A: The primary differences are maximum supply current (ECS part: 3mA versus Abracon part: 4mA) and maximum seated height (ECS part: 0.90mm versus Abracon part: 0.95mm). These differences do not affect functional compatibility.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive-grade qualification, confirming suitability for automotive-grade reliability requirements.

Q: What is the significance of the 4-SMD, No Lead package?

A: This package type indicates a surface-mount oscillator with four solder pads and no through-hole leads. Both parts use identical package geometry (2.50mm x 2.00mm), ensuring mechanical compatibility with the same PCB footprint.

Q: Do these parts require any special handling or storage considerations?

A: The ASDAIG3-27.000MHZ-X-K-T lists Moisture Sensitivity Level as Not Applicable. The ECS-2520Q-18-270-DP-TR lists MSL as 1 (Unlimited), indicating no moisture sensitivity restrictions for either part.
