Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7M-19.2000MAHI-T is permissible when the following criteria are satisfied:

Primary Substitution Criteria:

• Identical frequency: 19.2 MHz
• Identical frequency stability: ±30ppm
• Identical operating mode: Fundamental
• Identical operating temperature range: -40°C to 85°C
• Identical mounting type: Surface Mount
• Identical package type: 4-SMD, No Lead
• Compliance status: RoHS Compliant or higher (ROHS3)
• MSL rating: 1 (Unlimited)

Secondary Electrical Parameters (Allowable Variation): Load capacitance and ESR values may differ from the main part specification provided the substitute part is qualified for the target application circuit. The 8Z-19.200MAHE-T substitute exhibits a load capacitance of 12pF (versus 16pF on the main part) and ESR of 100 Ohms (versus 80 Ohms on the main part). These variations remain within acceptable ranges for 19.2 MHz crystal oscillator applications in standard microcontroller and timing circuits.

Parameter Comparison

Engineering Selection Recommendations

7M-19.2000MAHI-T Selection: Select the 7M-19.2000MAHI-T when the application circuit is designed for 16pF load capacitance and 80 Ohm ESR specifications. This part is Active status with RoHS Compliance and unlimited moisture sensitivity rating, suitable for standard industrial timing applications.

8Z-19.200MAHE-T Selection: The 8Z-19.200MAHE-T substitute is suitable when:

• The application circuit accommodates 12pF load capacitance and 100 Ohm ESR
• Smaller physical footprint (2.50mm x 2.00mm versus 3.20mm x 2.50mm) is advantageous for space-constrained PCB layouts
• Lower profile height (0.55mm versus 0.80mm) is required for low-profile assembly
• ROHS3 Compliance is specified as a requirement
• Tape & Reel packaging format is preferred for automated assembly

Both parts maintain identical frequency, stability, operating temperature range, and fundamental operating mode. Selection between these parts depends on circuit design parameters and physical constraints rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Can the 8Z-19.200MAHE-T directly replace the 7M-19.2000MAHI-T without circuit modification?

A: Direct replacement requires verification that the application circuit is designed to operate with 12pF load capacitance and 100 Ohm ESR. If the circuit was optimized for 16pF and 80 Ohm specifications, load capacitance matching network adjustment may be necessary. Consult the oscillator circuit design documentation.

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

A: Load capacitance determines the frequency-setting capacitor values in the oscillator circuit. The 7M-19.2000MAHI-T requires 16pF load capacitance matching, while the 8Z-19.200MAHE-T requires 12pF. Mismatched load capacitance can result in frequency deviation beyond the ±30ppm specification.

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

A: Yes. Both the 7M-19.2000MAHI-T and 8Z-19.200MAHE-T operate across -40°C to 85°C with identical ±30ppm frequency stability across this range.

Q: What packaging format differences exist between these parts?

A: The 7M-19.2000MAHI-T is supplied in standard packaging format. The 8Z-19.200MAHE-T is supplied in Tape & Reel (TR) format, which is optimized for high-volume automated assembly processes.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. The 7M-19.2000MAHI-T is RoHS Compliant. The 8Z-19.200MAHE-T is ROHS3 Compliant, which represents a higher compliance standard. Both are acceptable for RoHS-regulated applications.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life and no moisture sensitivity restrictions. These parts do not require special moisture control during storage or handling.
