Substitute Part Grouping Explanation

Equivalent and substitute parts for the 7V-24.000MEEV-T are classified based on the following criteria:

Parametric Equivalents maintain identical electrical specifications: 24 MHz frequency, ±30ppm stability, 8pF load capacitance, and 60 Ohms ESR. These parts differ only in packaging format (Cut Tape vs. Tape & Reel) and are direct functional replacements.

Similar Substitutes share the core frequency (24 MHz) and stability (±30ppm) but vary in ESR (100-150 Ohms) and/or load capacitance (8-10pF). These parts are compatible when circuit design tolerates higher ESR values or alternative load capacitance specifications.

Cross-Manufacturer Equivalents from Diodes Incorporated and QST maintain 24 MHz frequency and ±30ppm stability with comparable ESR and load capacitance ranges, enabling multi-source procurement strategies.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent): The 7V-24.000MAAV-T is a parametric equivalent with identical electrical specifications and physical dimensions. Selection between Tape & Reel (MEEV-T) and Cut Tape/Digi-Reel (MAAV-T) formats depends on procurement and assembly requirements. Both maintain Active product status and RoHS compliance.

Higher ESR Tolerance Applications: The 8Y-24.000MAAV-T and 8Z-24.000MAAV-T offer 100 Ohms ESR with reduced physical footprint (2.00 x 1.60 mm and 2.50 x 2.00 mm respectively). These are suitable for designs tolerating higher ESR values. Both are Active products with RoHS compliance.

Compact Footprint Selection: The 7R-24.000MAAV-T provides the smallest physical dimensions (2.05 x 1.65 mm) with 150 Ohms ESR, applicable to space-constrained designs where ESR tolerance permits. Available in Cut Tape format with Active product status.

Cross-Manufacturer Sourcing: The FH2400032Z (Diodes Incorporated) and QT325G-24.000MAAV-T (QST) maintain 24 MHz frequency and ±30ppm stability. The FH2400032Z features 10pF load capacitance and 50 Ohms ESR; the QT325G matches the original 8pF/60 Ohms specification. Both are Active products with enhanced RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can I substitute 7V-24.000MAAV-T for 7V-24.000MEEV-T? A: Yes. Both parts are parametric equivalents with identical electrical and mechanical specifications (24 MHz, ±30ppm, 8pF, 60 Ohms ESR, 3.20 x 2.50 mm). The difference is packaging format: MEEV-T is Tape & Reel; MAAV-T is Cut Tape & Digi-Reel. Selection depends on assembly line requirements.

Q: What is the impact of using 8Y-24.000MAAV-T or 8Z-24.000MAAV-T with higher ESR? A: These parts feature 100 Ohms ESR compared to the original 60 Ohms. Higher ESR increases power dissipation and may affect oscillator startup characteristics. Verify circuit design tolerance for ESR variation before substitution.

Q: Are the smaller footprint alternatives (7R-24.000MAAV-T) compatible? A: The 7R-24.000MAAV-T maintains 24 MHz frequency and ±30ppm stability but features 150 Ohms ESR and reduced dimensions (2.05 x 1.65 mm). Compatibility depends on circuit tolerance for higher ESR and available PCB space. Electrical performance may differ from the original specification.

Q: Can I use cross-manufacturer parts like FH2400032Z or QT325G-24.000MAAV-T? A: Yes, both maintain 24 MHz frequency and ±30ppm stability. The FH2400032Z has 10pF load capacitance and 50 Ohms ESR; the QT325G matches the original 8pF/60 Ohms specification. Verify circuit design compatibility with load capacitance and ESR variations.

Q: What packaging formats are available? A: Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® formats are available across the substitute parts. Selection depends on assembly equipment and procurement volume requirements. All parts use 4-SMD, No Lead package configuration.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed parts are RoHS Compliant or ROHS3 Compliant, meeting environmental regulatory requirements. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no moisture sensitivity constraints.
