Substitute Part Grouping Explanation

Substitute parts for the 7V-24.576MAHV-T are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Frequency: 24.576 MHz (exact match required)
• Frequency Stability: ±30 ppm (exact match required)
• Operating Mode: Fundamental (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: 3.20 mm x 2.50 mm (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Parameters:

• Load Capacitance: 8 pF (primary specification; 10 pF represents a variation within acceptable design margins for certain applications)
• ESR: 60 Ohms (primary specification; lower ESR values such as 40 Ohms are compatible with circuit designs accommodating this parameter)

Substitutes are grouped into two categories: direct equivalents (identical electrical and mechanical specifications) and parametric equivalents (matching all critical parameters with acceptable variations in load capacitance and ESR).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Parametric Match): The 7V-24.576MAHV-T manufactured by FTS is a parametric equivalent with identical electrical specifications (24.576 MHz, ±30 ppm stability, 8 pF load capacitance, 60 Ohms ESR) and mechanical form factor. Both TXC and FTS versions are RoHS Compliant and carry MSL 1 rating. This substitute provides identical circuit performance and PCB layout compatibility. FTS inventory availability (4105 Pcs) exceeds TXC availability (1099 Pcs).

Functional Substitute (Load Capacitance Variation): The ILCX13-FF5F10-24.576MHZ manufactured by ILSI matches all critical parameters (24.576 MHz, ±30 ppm stability, fundamental mode, -40 to 85°C operating range, 4-SMD package, 3.20 x 2.50 mm form factor) with a load capacitance specification of 10 pF and ESR of 40 Ohms. This part is ROHS3 Compliant and carries MSL 1 rating. The 10 pF load capacitance and 40 Ohms ESR represent acceptable variations for applications where circuit design accommodates these parameters. ILSI inventory (1916 Pcs) provides intermediate availability.

Selection Basis:

• All three parts share identical frequency, stability, operating temperature range, mounting type, and physical dimensions
• Substitution decisions should be based on circuit design specifications for load capacitance and ESR tolerance
• Packaging format (Tape & Reel vs. Cut Tape) affects procurement and assembly processes
• Inventory levels and lead times are secondary considerations after electrical and mechanical compatibility confirmation

Frequently Asked Questions (FAQ)

Q: Can the ILCX13-FF5F10-24.576MHZ (10 pF load capacitance) be used in place of the 7V-24.576MAHV-T (8 pF load capacitance)?

A: The ILCX13-FF5F10-24.576MHZ is functionally compatible if the circuit design accommodates a 10 pF load capacitance specification. The 2 pF difference and lower ESR (40 Ohms vs. 60 Ohms) must be evaluated against the specific oscillator circuit requirements. Load capacitance affects frequency accuracy and stability characteristics.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 4-SMD, No Lead package with identical 3.20 x 2.50 mm dimensions and 0.90 mm maximum seated height. PCB footprints and land patterns are interchangeable.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging is supplied on continuous reels suitable for automated pick-and-place assembly equipment. Cut Tape packaging is supplied in individual tape segments for manual handling or lower-volume assembly processes. Both formats contain the same component; packaging format affects procurement, storage, and assembly workflow.

Q: Do all parts meet RoHS compliance requirements?

A: The 7V-24.576MAHV-T (TXC and FTS) are RoHS Compliant. The ILCX13-FF5F10-24.576MHZ is ROHS3 Compliant. Both compliance levels satisfy RoHS Directive requirements; ROHS3 represents the current standard revision.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and does not require special moisture-controlled storage or handling procedures. No baking or desiccant storage is required prior to assembly.

Q: How do frequency stability specifications affect part selection?

A: All three parts specify ±30 ppm frequency stability over the -40 to 85°C operating range. This specification defines the maximum frequency deviation from the nominal 24.576 MHz value. Identical stability ratings ensure equivalent performance in frequency-critical applications.

Q: Can these parts be used interchangeably in all applications?

A: Interchangeability depends on circuit design specifications for load capacitance and ESR. The FTS 7V-24.576MAHV-T is a direct replacement with identical specifications. The ILSI ILCX13-FF5F10-24.576MHZ requires circuit design verification to confirm compatibility with 10 pF load capacitance and 40 Ohms ESR before substitution.
