Key Parameters

Substitute Part Grouping Explanation

Substitution of the AV-32.000MFHV-T is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 32.000 MHz (exact match required)
• Frequency Tolerance: ±15 ppm (maximum allowable deviation)
• Operating Mode: Fundamental
• Operating Temperature Range: -40°C to 85°C (minimum required coverage)
• Package / Case: 4-SMD, No Lead (mechanical and electrical interface compatibility)
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Load Capacitance: Substitutes with 10pF load capacitance are acceptable when circuit design accommodates the higher capacitive load
• ESR: Substitutes with higher ESR values (up to 100 Ohms) are acceptable provided circuit impedance matching remains within design specifications
• Physical Dimensions: Smaller footprints are acceptable; larger footprints require PCB layout verification
• Compliance Ratings: AEC-Q200 and RoHS compliance must be maintained or exceeded

The identified substitute EB1620JA10-32.000M TR meets all mandatory parameters while introducing acceptable variations in load capacitance and ESR that do not compromise functional compatibility in standard 32 MHz crystal oscillator applications.

Engineering Selection Recommendations

Primary Part Selection (AV-32.000MFHV-T): Select the AV-32.000MFHV-T when the original design specification calls for 8pF load capacitance and 60 Ohm ESR. This part maintains exact parameter alignment with established circuit designs and carries AEC-Q200 automotive qualification with RoHS compliance.

Substitute Part Selection (EB1620JA10-32.000M TR): The EB1620JA10-32.000M TR is functionally equivalent for 32 MHz crystal oscillator applications where circuit design accommodates 10pF load capacitance and 100 Ohm ESR. This substitute is qualified to AEC-Q200 and ROHS3 standards, exceeding baseline compliance requirements. The smaller physical footprint (2.00 x 2.50 mm vs. 3.20 x 2.50 mm) and lower profile (0.55 mm vs. 0.90 mm) provide layout advantages in space-constrained designs. Both parts operate across -40°C to 85°C and maintain ±15 ppm frequency tolerance.

Substitution Constraints: Substitution is valid only when the receiving circuit design has been verified to accept the load capacitance and ESR variations specified in the EB1620JA10-32.000M TR. Load capacitance and ESR directly affect oscillator startup characteristics and frequency accuracy; circuit simulation or empirical validation is required prior to production implementation when these parameters differ from the original design specification.

Frequently Asked Questions (FAQ)

Q: Can the EB1620JA10-32.000M TR directly replace the AV-32.000MFHV-T without circuit modification?

A: Direct replacement is possible only if the circuit design accommodates 10pF load capacitance and 100 Ohm ESR. The original circuit was designed for 8pF and 60 Ohm ESR. If the circuit design includes load capacitance tuning or was designed with margin for ESR variation, substitution is valid. If the circuit design is tightly coupled to the original 8pF/60 Ohm specification, circuit re-validation is required.

Q: What is the impact of the 2pF load capacitance difference?

A: Load capacitance affects the oscillation frequency and startup behavior. A 2pF increase shifts the resonant frequency slightly and may alter the phase margin of the oscillator circuit. The ±15 ppm tolerance specification accommodates minor frequency shifts, but the circuit must be designed to tolerate this variation or include frequency trimming capability.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the AV-32.000MFHV-T and EB1620JA10-32.000M TR carry AEC-Q200 qualification, confirming suitability for automotive-grade reliability requirements across the -40°C to 85°C operating range.

Q: What is the significance of the smaller physical dimensions of the EB1620JA10-32.000M TR?

A: The EB1620JA10-32.000M TR measures 2.00 x 1.60 mm compared to the AV-32.000MFHV-T at 3.20 x 2.50 mm. The smaller footprint reduces PCB area consumption and may improve high-frequency signal integrity in compact designs. The lower profile (0.55 mm vs. 0.90 mm) provides additional clearance in space-constrained assemblies. Both parts use identical 4-SMD, No Lead packaging, ensuring mechanical compatibility with standard pick-and-place equipment.

Q: Does the higher ESR of the EB1620JA10-32.000M TR affect circuit performance?

A: ESR (Equivalent Series Resistance) of 100 Ohms versus 60 Ohms increases energy dissipation in the crystal element. This affects oscillator startup time and power consumption. Circuits designed with adequate drive level margin accommodate this variation. High-impedance oscillator circuits or those with tight power budgets require validation before substitution.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts are AEC-Q200 qualified and RoHS compliant. The EB1620JA10-32.000M TR additionally carries ROHS3 compliance and REACH Unaffected status, exceeding the baseline RoHS requirement of the AV-32.000MFHV-T. Both parts carry EAR99 ECCN and 8541.60.0060 HTSUS classification.

Q: What packaging format is available for the EB1620JA10-32.000M TR?

A: The EB1620JA10-32.000M TR is supplied in Cut Tape (CT) packaging, suitable for automated assembly processes. Verify tape specifications and reel quantities align with production requirements before procurement.
