Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM-26.000MENV-T is determined by strict alignment of the following critical parameters:

Frequency and Tolerance: The substitute part must operate at 26.0000 MHz with ±10ppm frequency tolerance to ensure circuit timing specifications are met.

Load Capacitance: The substitute must be specified for 8pF load capacitance, as this value is determined by the circuit design and cannot be altered without redesign.

Package and Mounting: The substitute must use 4-SMD, No Lead surface mount packaging with dimensions of 3.20mm x 2.50mm to ensure PCB footprint compatibility and assembly process compatibility.

Operating Temperature Range: The substitute must support the full -40°C to 125°C operating range to function across the intended application environment.

Electrical Series Resistance (ESR): While the main part specifies 80 Ohms ESR, substitute parts with lower ESR values (such as 60 Ohms) remain functionally compatible as ESR is a performance characteristic that does not prevent substitution when lower values are present.

Compliance and Ratings: The substitute must maintain AEC-Q200 automotive qualification and RoHS compliance status to preserve design certifications and regulatory requirements.

The XR32H1I026.000060Q from Diodes Incorporated meets all critical substitution criteria while offering improved ESR performance and equivalent moisture sensitivity classification.

Engineering Selection Recommendations

Primary Part Selection: The AM-26.000MENV-T remains the specified component for new designs and existing production runs where supply is available. This part maintains active product status with 657 units in current inventory.

Substitute Selection Criteria: The XR32H1I026.000060Q is qualified as a direct substitute when the AM-26.000MENV-T is unavailable or when supply chain optimization is required. Both parts carry identical AEC-Q200 automotive qualification and RoHS compliance certifications, ensuring design integrity is preserved.

Performance Considerations: The XR32H1I026.000060Q offers a 20 Ohm reduction in ESR (60 Ohms versus 80 Ohms), which represents improved electrical performance characteristics. The substitute also provides a lower seated height of 0.70mm compared to 0.80mm, offering potential benefits for space-constrained applications. These differences do not compromise substitution eligibility.

Compliance Preservation: Both parts maintain identical operating temperature ranges (-40°C to 125°C), load capacitance specifications (8pF), frequency tolerance (±10ppm), and moisture sensitivity classification (MSL 1). Regulatory compliance status is preserved through equivalent RoHS certifications.

Inventory Availability: The XR32H1I026.000060Q is available in higher quantity (2788 units) compared to the primary part, supporting extended production schedules and supply chain resilience.

Frequently Asked Questions (FAQ)

Q: Can the XR32H1I026.000060Q be used as a direct replacement for the AM-26.000MENV-T without circuit modifications?

A: Yes. Both parts are specified for identical frequency (26.0000 MHz), frequency tolerance (±10ppm), load capacitance (8pF), operating temperature range (-40°C to 125°C), and package dimensions (3.20mm x 2.50mm). The 20 Ohm ESR difference does not require circuit redesign.

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

A: ESR (Equivalent Series Resistance) is an electrical characteristic that affects oscillator startup behavior and power consumption. The XR32H1I026.000060Q at 60 Ohms provides lower ESR than the AM-26.000MENV-T at 80 Ohms. Lower ESR generally improves oscillator performance and is not a limiting factor for substitution.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the AM-26.000MENV-T and XR32H1I026.000060Q carry AEC-Q200 automotive-grade qualification, confirming suitability for automotive and industrial applications requiring this certification level.

Q: Do the parts have identical moisture sensitivity requirements?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: What is the physical difference in height between these parts?

A: The AM-26.000MENV-T has a maximum seated height of 0.80mm, while the XR32H1I026.000060Q measures 0.70mm. This 0.10mm difference may be relevant for applications with strict height constraints but does not affect electrical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. The AM-26.000MENV-T is RoHS Compliant, and the XR32H1I026.000060Q is ROHS3 Compliant. Both meet current RoHS regulatory requirements.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Both parts use identical 4-SMD, No Lead packaging with 3.20mm x 2.50mm footprints, ensuring PCB layout compatibility without modification.

Q: What is the frequency stability specification for both parts?

A: Both parts specify ±50ppm frequency stability across the -40°C to 125°C operating temperature range, ensuring equivalent temperature drift performance.
