Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7M10072001 crystal is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 10 MHz (exact match required)
• Package / Case: 4-SMD, No Lead (physical and electrical interface compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Footprint Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) (PCB layout compatibility)

Allowable Variation Parameters:

• Load Capacitance: 9pF (primary specification); substitutes with 8pF load capacitance are acceptable within circuit design tolerance
• Frequency Tolerance: ±7ppm (primary); ±20ppm tolerance acceptable for applications with relaxed frequency accuracy requirements
• Frequency Stability: ±18ppm (primary); ±30ppm stability acceptable for non-critical timing applications
• Operating Temperature Range: -40°C ~ 105°C (primary); -40°C ~ 85°C acceptable for applications not requiring extended high-temperature operation
• Height - Seated (Max): 0.031" (0.80mm) (primary); 0.035" (0.90mm) acceptable for designs with adequate PCB clearance

The 7V10080005 substitute part maintains frequency, package, and mounting compatibility while introducing acceptable variations in load capacitance, frequency tolerance, stability, and thermal operating range.

Engineering Selection Recommendations

Primary Substitute: 7V10080005

The 7V10080005 is the recommended substitute for the obsolete 7M10072001 based on the following engineering criteria:

Compatibility Factors:

• Identical frequency (10 MHz) and package footprint (3.20mm x 2.50mm, 4-SMD No Lead) ensure direct PCB layout compatibility
• Same manufacturer (TXC CORPORATION) provides consistent design and manufacturing standards
• Identical MSL rating (1, Unlimited) maintains moisture handling requirements
• Active product status ensures ongoing availability and supply chain continuity

Performance Considerations:

• Frequency tolerance widens from ±7ppm to ±20ppm; acceptable for applications where frequency accuracy is not critical to system performance
• Frequency stability increases from ±18ppm to ±30ppm; acceptable for non-precision timing applications
• Load capacitance reduces from 9pF to 8pF; circuit-level validation required to confirm oscillator startup and frequency accuracy within the application's tuning network
• Operating temperature range narrows from -40°C ~ 105°C to -40°C ~ 85°C; acceptable for applications not requiring extended high-temperature operation above 85°C
• Maximum seated height increases from 0.031" (0.80mm) to 0.035" (0.90mm); acceptable provided PCB clearance accommodates the additional 0.004" (0.10mm)

Compliance Advantages:

• 7V10080005 carries RoHS Compliant and REACH Unaffected certifications, supporting modern regulatory requirements
• 7M10072001 compliance certifications are not specified

Selection Criteria: Select the 7V10080005 substitute when:

• Supply of the obsolete 7M10072001 is unavailable
• Application frequency accuracy requirements tolerate ±20ppm tolerance
• Operating temperature does not exceed 85°C
• PCB design accommodates 0.035" (0.90mm) maximum seated height
• Load capacitance of 8pF is compatible with the oscillator circuit design

Frequently Asked Questions (FAQ)

Q: Can the 7V10080005 be used as a direct replacement for the 7M10072001 without circuit modifications?

A: The 7V10080005 maintains identical frequency, package, and footprint specifications. However, the 1pF load capacitance difference (9pF to 8pF) may require oscillator circuit tuning validation. Frequency tolerance and stability specifications are wider in the substitute part. Direct substitution is feasible only after confirming that the application's frequency accuracy and stability requirements are met by the ±20ppm tolerance and ±30ppm stability of the 7V10080005.

Q: What is the impact of the load capacitance difference between the two parts?

A: The 7M10072001 specifies 9pF load capacitance, while the 7V10080005 specifies 8pF. This 1pF difference affects the oscillator's tuning network and may shift the operating frequency within the tolerance band. Circuit-level analysis of the load capacitance network is required to determine if the 8pF specification remains compatible with the application's frequency accuracy requirements.

Q: Are there thermal operating range limitations with the 7V10080005?

A: The 7V10080005 operates from -40°C to 85°C, compared to the 7M10072001 range of -40°C to 105°C. The substitute part is not suitable for applications requiring operation above 85°C. Verify that the application's maximum operating temperature does not exceed 85°C before selecting this substitute.

Q: Does the height difference between the two parts affect PCB assembly?

A: The 7V10080005 has a maximum seated height of 0.035" (0.90mm), compared to 0.031" (0.80mm) for the 7M10072001. This 0.004" (0.10mm) increase is typically accommodated in standard PCB designs. Verify that the PCB clearance profile and any overlying components provide adequate spacing for the taller package height.

Q: What compliance certifications does the 7V10080005 carry?

A: The 7V10080005 is RoHS Compliant and REACH Unaffected. The 7M10072001 compliance certifications are not specified. If regulatory compliance is a requirement, the 7V10080005 provides documented RoHS and REACH status.

Q: Is the 7V10080005 currently available in production?

A: Yes. The 7V10080005 carries Active product status, indicating current production and ongoing supply chain availability. The 7M10072001 is classified as Obsolete, making the 7V10080005 the recommended long-term supply solution.

Q: What is the significance of the ESR (Equivalent Series Resistance) specification in the 7V10080005?

A: The 7V10080005 specifies 150 Ohms ESR. ESR affects the crystal's impedance characteristics and power consumption in the oscillator circuit. The 7M10072001 does not provide an ESR specification. If the application has specific ESR requirements, the 150 Ohms value of the 7V10080005 must be validated against the oscillator circuit design.

Q: Can the 7V10080005 be used in high-precision timing applications?

A: The 7V10080005 frequency tolerance of ±20ppm and stability of ±30ppm are wider than the 7M10072001 specifications (±7ppm tolerance, ±18ppm stability). High-precision timing applications requiring tighter frequency accuracy should evaluate whether the ±20ppm tolerance of the 7V10080005 meets the system's frequency accuracy budget before substitution.
