AV-24.000MDGE-T Equivalent & Substitute Parts

Part Overview

The AV-24.000MDGE-T is a 24 MHz fundamental mode crystal oscillator manufactured by TXC CORPORATION. This surface mount device is designed for applications requiring precise frequency generation with a load capacitance of 12pF and operates across the industrial temperature range of -40°C to 85°C. The part is currently in active production status and maintains AEC-Q200 automotive-grade qualification. Substitute parts are identified when original inventory is unavailable, when alternative electrical characteristics better suit specific circuit requirements, or when supply chain optimization is necessary while maintaining functional equivalence.

Substitute Part Grouping Explanation

Substitution of the AV-24.000MDGE-T is permissible when the replacement part meets the following criteria:

Critical Matching Parameters:

• Frequency: 24.0000 MHz (exact match required)
• Frequency Tolerance: ±20 ppm (substitute must not exceed this tolerance)
• Load Capacitance: 12 pF (exact match required for circuit oscillation)
• Operating Temperature Range: -40°C to 85°C (substitute must cover this full range)
• Mounting Type: Surface Mount (required for PCB assembly compatibility)
• Package / Case: 4-SMD, No Lead (required for footprint compatibility)
• Physical Dimensions: 3.20mm L x 2.50mm W (required for PCB layout compatibility)

Acceptable Variation Parameters:

• ESR (Equivalent Series Resistance): Substitute values equal to or lower than 60 Ohms are acceptable, as lower ESR improves circuit performance and reduces power consumption
• RoHS Compliance: Substitute must maintain RoHS compliance status (RoHS3 Compliant is acceptable)
• AEC-Q200 Rating: Substitute must maintain automotive-grade qualification

The ECS-240-12-33Q-JEN-TR meets all critical matching parameters and acceptable variation criteria, qualifying it as a direct substitute.

Engineering Selection Recommendations

Primary Part Selection (AV-24.000MDGE-T): The AV-24.000MDGE-T remains the preferred selection when available. This part is manufactured by TXC CORPORATION, maintains active production status, and carries AEC-Q200 automotive-grade qualification. The part is RoHS Compliant and operates across the full industrial temperature range with 12 pF load capacitance and 60 Ohms ESR.

Substitute Part Selection (ECS-240-12-33Q-JEN-TR): The ECS-240-12-33Q-JEN-TR manufactured by ECS Inc. is a qualified substitute when the primary part is unavailable. This substitute maintains identical frequency, tolerance, load capacitance, operating temperature range, and package specifications. The substitute offers improved electrical characteristics with 40 Ohms ESR (lower than the primary part) and a reduced seated height of 0.80 mm versus 0.90 mm. Both parts maintain AEC-Q200 automotive qualification and RoHS compliance (ROHS3 Compliant). The substitute is available in higher inventory quantities (4480 Pcs versus 830 Pcs for the primary part).

Selection Criteria:

• Use AV-24.000MDGE-T when TXC CORPORATION supply is available and cost is not a primary constraint
• Use ECS-240-12-33Q-JEN-TR when supply optimization, improved ESR performance, or reduced component height is beneficial
• Both parts are functionally equivalent for 24 MHz crystal oscillator applications requiring 12 pF load capacitance and automotive-grade reliability

Frequently Asked Questions (FAQ)

Q: Can the ECS-240-12-33Q-JEN-TR be used as a direct replacement for the AV-24.000MDGE-T on existing PCBs?

A: Yes. Both parts share identical frequency (24.0000 MHz), frequency tolerance (±20 ppm), load capacitance (12 pF), physical dimensions (3.20mm x 2.50mm), and package type (4-SMD, No Lead). The substitute has a lower seated height (0.80 mm versus 0.90 mm), which is acceptable for PCB assembly. No circuit redesign or PCB layout modification is required.

Q: What is the significance of the ESR difference between these parts?

A: The AV-24.000MDGE-T has 60 Ohms ESR while the ECS-240-12-33Q-JEN-TR has 40 Ohms ESR. Lower ESR reduces power consumption in the oscillator circuit and improves frequency stability. The substitute part's lower ESR is a performance advantage and does not create compatibility issues.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the AV-24.000MDGE-T and ECS-240-12-33Q-JEN-TR carry AEC-Q200 automotive-grade qualification, confirming suitability for automotive temperature and reliability requirements.

Q: What is the difference in RoHS compliance between these parts?

A: The AV-24.000MDGE-T is RoHS Compliant (standard RoHS). The ECS-240-12-33Q-JEN-TR is ROHS3 Compliant, which represents the current RoHS directive revision. Both parts meet environmental compliance requirements. ROHS3 Compliant status indicates the substitute meets the latest regulatory standards.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the circuit design specifies 24 MHz frequency, ±20 ppm tolerance, and 12 pF load capacitance. Both parts meet these specifications and maintain identical operating temperature ranges (-40°C to 85°C). Substitution does not require circuit validation or design changes.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use 4-SMD, No Lead package with identical dimensions of 3.20mm L x 2.50mm W. The ECS-240-12-33Q-JEN-TR has a slightly lower seated height (0.80 mm versus 0.90 mm), which does not affect PCB footprint compatibility or assembly.
