Substitute Part Grouping Explanation
Substitute parts for the 8Q-24.000MDDV-T are identified based on strict electrical and mechanical parameter compatibility. The substitution logic is organized into two categories:
Category 1: Similar Manufacturer Part (Load Capacitance Variant) The 8Q-24.000MDDQ-T shares identical frequency, frequency stability, ESR, operating mode, temperature range, package type, physical dimensions, and compliance certifications. The single parameter difference is load capacitance: 10pF versus 8pF. This part is substitutable in applications where the circuit design accommodates 10pF load capacitance without affecting frequency accuracy or system performance.
Category 2: Parametric Equivalent (Different Manufacturer) The 8Q-24.000MDDV-T manufactured by FTS provides complete electrical and mechanical equivalence to the primary TXC CORPORATION part. All critical parameters match: 24 MHz frequency, ±20ppm stability, 8pF load capacitance, 100 Ohms ESR, 4-SMD No Lead package, identical physical dimensions, and operating temperature range. This part is a direct parametric equivalent suitable for cross-manufacturer substitution.
Key Parameters Determining Substitutability:
- Frequency: 24 MHz (mandatory match)
- Frequency Stability: ±20ppm (mandatory match)
- Load Capacitance: 8pF (primary specification; 10pF variant available with circuit design verification)

Engineering Selection Recommendations
Primary Selection: 8Q-24.000MDDV-T (TXC CORPORATION) This is the original specified part with confirmed Active product status, RoHS Compliance, and MSL 1 rating. Current inventory: 803 Pcs New Original In Stock. Selection is appropriate for standard procurement when TXC supply is available.
First Substitute: 8Q-24.000MDDV-T (FTS) This part provides complete parametric equivalence with identical electrical specifications and physical dimensions. Manufacturer FTS offers Active product status and RoHS Compliance. Current inventory: 6420 Pcs New Original In Stock. This substitute is suitable for direct replacement in applications where cross-manufacturer sourcing is acceptable. Selection is appropriate when TXC supply is constrained.
Second Substitute: 8Q-24.000MDDQ-T (TXC CORPORATION) This part differs only in load capacitance specification (10pF versus 8pF). Both parts maintain identical frequency, stability, ESR, package, and temperature range. Selection requires circuit design verification to confirm that 10pF load capacitance is compatible with the oscillator circuit. Current inventory: 11588 Pcs New Original In Stock. This substitute is appropriate for applications where load capacitance tolerance has been validated or where circuit design permits the higher capacitance value.
Compliance Considerations: All three parts maintain RoHS compliance and MSL 1 (Unlimited) moisture sensitivity rating, supporting deployment in standard manufacturing environments without special handling requirements.
Frequently Asked Questions (FAQ)
Q1: Can the 8Q-24.000MDDQ-T (10pF) be used as a direct replacement for the 8Q-24.000MDDV-T (8pF)?
A: The 8Q-24.000MDDQ-T is electrically and mechanically compatible with identical frequency, stability, ESR, package, and temperature specifications. However, the load capacitance differs (10pF versus 8pF). Direct substitution requires verification that the circuit design accommodates 10pF load capacitance without affecting frequency accuracy, phase noise, or system performance. Load capacitance affects the oscillator's frequency pulling range and startup characteristics.
Q2: Is the FTS-manufactured 8Q-24.000MDDV-T equivalent to the TXC CORPORATION version?
A: Yes. The FTS part provides complete parametric equivalence: identical 24 MHz frequency, ±20ppm stability, 8pF load capacitance, 100 Ohms ESR, 4-SMD No Lead package, 1.60mm x 1.20mm dimensions, and -20°C to 70°C operating temperature. Both parts are Active status with RoHS Compliance and MSL 1 rating. Cross-manufacturer substitution is supported based on electrical and mechanical parameter matching.
Q3: What are the critical parameters that determine substitutability for 24 MHz crystals?
A: Substitutability is determined by: (1) Frequency match at 24 MHz, (2) Frequency stability at ±20ppm, (3) Load capacitance specification, (4) ESR at 100 Ohms, (5) Operating mode (Fundamental), (6) Package type (4-SMD, No Lead), (7) Physical dimensions (1.60mm x 1.20mm), and (8) Operating temperature range (-20°C to 70°C). Deviation in any of these parameters requires circuit design evaluation.
Q4: Are there moisture sensitivity or handling differences between these parts?
A: No. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard surface mount assembly processes and storage conditions apply uniformly across all substitute options.
Q5: What inventory considerations apply to these substitutes?
A: Current stock levels are: 8Q-24.000MDDV-T (TXC) - 803 Pcs; 8Q-24.000MDDQ-T (TXC) - 11588 Pcs; 8Q-24.000MDDV-T (FTS) - 6420 Pcs. The TXC 10pF variant offers the highest immediate availability. The FTS equivalent provides substantial inventory with parametric equivalence to the primary part.
Q6: Do all parts support the same operating temperature range?
A: Yes. All three parts operate across -20°C to 70°C, supporting identical thermal performance specifications for standard industrial and commercial applications.
