Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7M-19.200MAHC-T is permissible when the following critical parameters remain constant:

Mandatory Matching Parameters:

• Frequency: 19.2 MHz (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Size / Dimension: 3.20mm x 2.50mm (exact match required)

Allowable Variation Parameters:

• Load Capacitance: Substitutes may vary within circuit design tolerance (9pF main part vs. 8pF substitute)
• ESR (Equivalent Series Resistance): Substitutes may vary within oscillator circuit design tolerance (80 Ohms main part vs. 60 Ohms substitute)
• Height - Seated (Max): Must not exceed 0.80mm maximum
• Moisture Sensitivity Level: MSL 1 is acceptable for both parts

The substitute part 7M-19.200MAHV-T meets all mandatory matching parameters while demonstrating acceptable variation in load capacitance and ESR within typical crystal oscillator circuit design margins.

Engineering Selection Recommendations

Primary Part Selection (7M-19.200MAHC-T): The 7M-19.200MAHC-T is the specified component with active production status and RoHS compliance. This part is suitable for applications where TXC CORPORATION sourcing is preferred or contractually required. The part carries REACH Unaffected status and EAR99 export classification.

Substitute Part Selection (7M-19.200MAHV-T): The 7M-19.200MAHV-T manufactured by FTS is electrically and mechanically compatible for applications where the load capacitance tolerance of 8pF and ESR of 60 Ohms fall within circuit design specifications. This substitute is appropriate when:

• Higher inventory availability is required (3957 units vs. 1006 units)
• FTS sourcing is acceptable within supply chain requirements
• Circuit design accommodates the specified load capacitance and ESR variations
• RoHS compliance is required (both parts are compliant)

Both parts maintain identical frequency, frequency stability, operating temperature range, package dimensions, and MSL rating. Selection between these parts depends on supply availability, sourcing preferences, and circuit design validation of the load capacitance and ESR parameters.

Frequently Asked Questions (FAQ)

Q: Can the 7M-19.200MAHV-T directly replace the 7M-19.200MAHC-T in my circuit?

A: Direct replacement is possible if your oscillator circuit design accommodates the load capacitance variation from 9pF to 8pF and the ESR variation from 80 Ohms to 60 Ohms. The identical frequency (19.2 MHz), frequency stability (±30ppm), operating temperature range (-40°C to 85°C), and package dimensions (3.20mm x 2.50mm) ensure physical and functional compatibility. Circuit validation is required to confirm that the specified load capacitance and ESR values remain within acceptable operating margins.

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

A: Load capacitance (9pF vs. 8pF) affects the crystal oscillator circuit's tuning characteristics. The oscillator circuit is designed to operate at a specific load capacitance value. A 1pF difference may require minor adjustments to the external load capacitors in the oscillator circuit to maintain frequency accuracy within the ±30ppm specification. Circuit design validation is necessary to confirm compatibility.

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

A: Equivalent Series Resistance (ESR) affects the crystal's ability to start oscillation and maintain stable operation. The 7M-19.200MAHV-T has lower ESR (60 Ohms vs. 80 Ohms), which generally indicates easier startup and lower power consumption. This variation is typically acceptable within standard oscillator circuit designs, but circuit validation is recommended.

Q: Are both parts RoHS compliant?

A: Yes, both the 7M-19.200MAHC-T and 7M-19.200MAHV-T are RoHS Compliant. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What is the difference in packaging between these parts?

A: The 7M-19.200MAHC-T is supplied in standard packaging, while the 7M-19.200MAHV-T is supplied in Tape & Reel (TR) format. Both use identical 4-SMD, No Lead package cases with 3.20mm x 2.50mm dimensions and 0.80mm maximum seated height. Tape & Reel packaging is standard for high-volume surface mount assembly operations.

Q: Which part should I select for new designs?

A: For new designs, either part is acceptable provided circuit design validation confirms compatibility with the specified load capacitance and ESR parameters. Selection should be based on supply chain requirements, sourcing preferences, and inventory availability. Both parts are in active production status with RoHS compliance.
