Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Eligibility:

The ASE-1.8432MHZ-L-C-T is a qualified direct substitute for the 7X-1.8432MBE-T based on electrical and mechanical parameter equivalence. Both devices share identical frequency, output type, supply voltage, enable/disable function, frequency stability, operating temperature range, package configuration, and physical dimensions.

Compliance Status:

Both parts maintain active product status and comply with RoHS, REACH, and export control requirements (ECCN EAR99, HTSUS 8542.39.0001). The ASE variant carries ROHS3 compliance, which represents an enhanced regulatory position relative to standard RoHS compliance.

Operational Considerations:

The ASE-1.8432MHZ-L-C-T demonstrates lower maximum supply current (7mA versus 20mA) and includes specified disable-mode current (10µA), providing potential power efficiency advantages in applications utilizing the enable/disable function. The substitute part exhibits a maximum seated height of 0.047" (1.20mm) compared to 0.043" (1.10mm) for the original part, representing a 0.004" (0.10mm) increase in vertical profile.

Supply Chain Availability:

The ASE-1.8432MHZ-L-C-T maintains significantly higher inventory availability (24,144 pieces versus 875 pieces), supporting extended production runs and reducing supply chain risk. The substitute is supplied in Tape & Reel packaging, standard for high-volume surface mount assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the ASE-1.8432MHZ-L-C-T replace the 7X-1.8432MBE-T in existing designs without modification?

A: Yes. The ASE-1.8432MHZ-L-C-T is electrically and mechanically equivalent across all critical parameters: frequency, output type, supply voltage, enable/disable function, frequency stability, operating temperature range, package type, and physical dimensions. No circuit modifications are required.

Q: What is the significance of the 0.004" (0.10mm) height difference?

A: The ASE variant has a maximum seated height of 0.047" (1.20mm) versus 0.043" (1.10mm) for the original part. This difference is within typical PCB assembly tolerances and should not impact board-level clearance in standard designs. Verify clearance in applications with height-constrained layouts.

Q: Does the lower supply current of the ASE part affect performance?

A: No. The ASE-1.8432MHZ-L-C-T operates within the same electrical specifications and frequency stability requirements. The lower maximum supply current (7mA versus 20mA) reflects improved power efficiency and does not compromise output characteristics or frequency accuracy.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both represent RoHS compliance. ROHS3 indicates compliance with the most current RoHS Directive revision. Both parts meet the same hazardous substance restrictions and are suitable for equivalent applications.

Q: Are there any differences in packaging that affect assembly?

A: The ASE-1.8432MHZ-L-C-T is supplied in Tape & Reel (TR) packaging, standard for automated surface mount assembly. The original part packaging is not specified. Tape & Reel format is compatible with standard pick-and-place equipment and does not require design changes.

Q: Can I use the ASE part in applications requiring the disable-mode current specification?

A: Yes. The ASE-1.8432MHZ-L-C-T specifies a maximum disable-mode current of 10µA, enabling precise power consumption calculations for applications utilizing the enable/disable function. The original part does not specify this parameter.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 7X-1.8432MBE-T and ASE-1.8432MHZ-L-C-T operate across -40°C to 85°C, meeting identical temperature specifications for industrial and commercial applications.

Q: What is the inventory advantage of selecting the ASE substitute?

A: The ASE-1.8432MHZ-L-C-T maintains 24,144 pieces in stock compared to 875 pieces for the original part. This 27-fold inventory advantage supports extended production schedules and reduces lead time risk for high-volume manufacturing.
