7V-12.000MDDV-T Crystal Oscillator Equivalent & Substitute Parts

Part Overview

The 7V-12.000MDDV-T is a 12 MHz fundamental mode crystal oscillator manufactured by TXC CORPORATION in active product status. This surface mount device is specified for 8pF load capacitance with ±20ppm frequency stability across the -20°C to 70°C operating temperature range. The component is packaged in a 4-SMD, No Lead configuration measuring 3.20mm × 2.50mm with 0.90mm maximum seated height, suitable for high-density PCB applications requiring compact form factors and RoHS compliance.

Substitute parts are identified when equivalent electrical performance can be maintained within the specified operating parameters while accommodating different load capacitance requirements in circuit design.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for 12 MHz crystal oscillators is determined by matching the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 12.0000 MHz
• Frequency Stability: ±20ppm
• ESR: 150 Ohms
• Operating Mode: Fundamental
• Operating Temperature Range: -20°C to 70°C
• Package / Case: 4-SMD, No Lead
• Physical Dimensions: 3.20mm × 2.50mm
• Height - Seated (Max): 0.90mm
• Mounting Type: Surface Mount

Allowable Variation Parameter:

• Load Capacitance: 8pF (main part) to 10pF (substitute part)

The 7V-12.000MDDQ-T qualifies as a direct substitute because it maintains identical frequency, stability, ESR, operating mode, temperature range, package configuration, and physical dimensions. The load capacitance difference (10pF versus 8pF) is an allowable variation when the circuit design accommodates the specified load capacitance of the substitute component.

Engineering Selection Recommendations

Primary Part Selection (7V-12.000MDDV-T): Select this part when circuit design specifies 8pF load capacitance. The component is in active product status with RoHS compliance and unlimited moisture sensitivity rating (MSL 1), suitable for standard manufacturing and storage conditions.

Substitute Part Selection (7V-12.000MDDQ-T): Select this part when circuit design accommodates 10pF load capacitance. The substitute maintains identical electrical performance across all critical parameters and offers higher inventory availability (5761 pcs versus 753 pcs). Both parts carry active product status and full RoHS compliance certifications.

Compliance Considerations: Both parts are RoHS compliant and REACH unaffected. The 7V-12.000MDDQ-T carries ROHS3 certification, providing enhanced regulatory alignment for applications requiring the latest compliance standards. Both components are classified under ECCN EAR99 and HTSUS 8541.60.0050.

Frequently Asked Questions (FAQ)

Q: Can the 7V-12.000MDDQ-T replace the 7V-12.000MDDV-T in any application?

A: Substitution is valid only when the circuit design is specified for 10pF load capacitance. The load capacitance parameter directly affects oscillator frequency stability and startup characteristics. Circuit design must accommodate the substitute part's 10pF specification.

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

A: Load capacitance (8pF versus 10pF) is a circuit-dependent parameter that affects the oscillator's frequency tuning and stability performance. The crystal must be matched to the load capacitance specified in the circuit design. Mismatched load capacitance can result in frequency deviation outside the ±20ppm specification.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both the 7V-12.000MDDV-T and 7V-12.000MDDQ-T measure 3.20mm × 2.50mm with 0.90mm maximum seated height. Both use identical 4-SMD, No Lead packaging and surface mount configuration, ensuring PCB footprint compatibility.

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

A: Both certifications indicate RoHS compliance. ROHS3 represents the current version of the RoHS directive. Both parts meet regulatory requirements; ROHS3 designation on the substitute part indicates alignment with the latest compliance standard.

Q: Which part should be selected for new designs?

A: Select the part that matches your circuit design's load capacitance specification. If the design specifies 8pF, use 7V-12.000MDDV-T. If the design specifies 10pF, use 7V-12.000MDDQ-T. Both parts are in active product status and suitable for new designs.

Q: Are there any temperature or operating condition differences between these parts?

A: No. Both parts operate identically across the -20°C to 70°C temperature range with ±20ppm frequency stability. Operating conditions and environmental specifications are identical.
