7M48020003 48 MHz Crystal Equivalent & Substitute Parts

Part Overview

The 7M48020003 is a 48 MHz surface mount crystal manufactured by TXC CORPORATION, designed for applications requiring precise frequency generation at 48 MHz with ±30ppm stability. This part is classified as an Active product with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). The 4-SMD, No Lead package with 10pF load capacitance serves as the reference specification for identifying electrically and mechanically compatible substitute components. Alternative parts may be required due to inventory constraints, lead time considerations, or specific application requirements within the allowed parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7M48020003 is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 48.0000 MHz (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• RoHS Compliance Status: RoHS Compliant or ROHS3 Compliant (equivalent)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Load Capacitance: 8pF to 10pF (within circuit design tolerance)
• ESR (Equivalent Series Resistance): 60 Ohms to 80 Ohms (within circuit design tolerance)
• Physical Dimensions: Minor variations acceptable if 4-SMD, No Lead package footprint is maintained
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) acceptable for equivalent electrical performance

All substitute parts listed below satisfy the mandatory matching parameters and fall within allowable variation ranges for load capacitance and ESR.

Parameter Comparison

Engineering Selection Recommendations

7M-48.000MAHV-T (TXC CORPORATION)

This substitute maintains identical frequency, stability, temperature range, and package footprint (3.20mm × 2.50mm × 0.80mm) to the main part. The load capacitance differs at 8pF versus 10pF, and ESR is specified at 60 Ohms. Both parts are manufactured by TXC CORPORATION with Active product status and RoHS compliance. This part is suitable for applications where the 8pF load capacitance falls within circuit design tolerance. Significantly higher inventory availability (28,401 pcs) supports supply chain continuity.

ILCX19-FF5F10-48.000MHZ (ILSI)

This substitute matches the main part in frequency, stability, temperature range, load capacitance (10pF), and package type (4-SMD, No Lead). Physical dimensions are smaller (2.00mm × 1.60mm × 0.55mm max), which may require PCB layout verification for footprint compatibility. ESR is specified at 60 Ohms. ROHS3 compliance is equivalent to RoHS compliance. Active product status and MSL 1 rating are maintained. This part is suitable for space-constrained applications where the smaller footprint is advantageous.

XZAEELNANF-48.000000 (Taitien)

This substitute matches the main part in frequency, stability, temperature range, and package type (4-SMD, No Lead). Load capacitance is 8pF with ESR at 80 Ohms. Physical dimensions are smaller (2.05mm × 1.65mm × 0.55mm max). ROHS3 compliance and MSL 1 rating are maintained with Active product status. This part is suitable for applications where the 8pF load capacitance and 80 Ohms ESR are within circuit design tolerance and space constraints favor the smaller footprint.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 7M48020003 with a part having different load capacitance?

A: Load capacitance variation between 8pF and 10pF is allowable if the circuit design accommodates the difference. The load capacitance value affects the crystal's resonant frequency in the circuit. Verify that your circuit design parameters support the substitute part's load capacitance specification before implementation.

Q: Are all substitute parts pin-compatible with the 7M48020003?

A: All substitute parts use the 4-SMD, No Lead package type, which maintains electrical pin compatibility. However, physical footprint dimensions vary. The 7M-48.000MAHV-T maintains identical dimensions (3.20mm × 2.50mm). The ILCX19-FF5F10-48.000MHZ and XZAEELNANF-48.000000 have smaller footprints (2.00mm × 1.60mm and 2.05mm × 1.65mm respectively). PCB layout verification is required for the smaller footprint parts.

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

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the directive. For the purposes of this substitution, both compliance statuses are equivalent and acceptable.

Q: Does ESR variation affect circuit performance?

A: ESR (Equivalent Series Resistance) values range from 60 Ohms to 80 Ohms across the substitute parts. ESR affects the crystal's impedance characteristics and power dissipation. Verify that your circuit design parameters support the substitute part's ESR specification. The main part does not specify ESR, so any substitute with specified ESR within the 60–80 Ohms range is acceptable if the circuit design accommodates it.

Q: Can I use the smaller footprint crystals (ILCX19 or XZAEELNANF) as direct replacements?

A: Electrical substitution is valid; however, PCB layout modification is required. The smaller footprint parts (2.00mm × 1.60mm or 2.05mm × 1.65mm) cannot use the same PCB pads designed for the 3.20mm × 2.50mm footprint. Verify PCB layout compatibility and reflow soldering parameters before implementation.

Q: Are all substitute parts available in the same packaging format?

A: No. The 7M-48.000MAHV-T is supplied in Tape & Reel (TR) format. The ILCX19-FF5F10-48.000MHZ and XZAEELNANF-48.000000 are supplied in Cut Tape (CT) format. Select the packaging format that matches your assembly process requirements.

Q: What is the MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required before soldering.
