Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LFXTAL059646 are classified as parametric equivalents based on the following criteria:

Substitution-Determining Parameters:

• Frequency: 30.0000 MHz (exact match required)
• Frequency Tolerance: ±20 ppm (exact match required)
• Load Capacitance: 18 pF (exact match required)
• ESR: 40 Ohms (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 3.20 × 2.50 × 0.80 mm (exact match required)
• Operating Temperature Range: -40°C to +85°C (exact match required)
• Operating Mode: Fundamental (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the LFXTAL059646 in applications designed for this specification set.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—LFXTAL059646, 830059646, ABM8-30.000MHZ-D2Y-T, and XC32M4-30.000-F18JJDTK—are active production parts with ROHS3 compliance and REACH unaffected status. They are electrically and mechanically equivalent for applications requiring a 30 MHz fundamental mode crystal with 18 pF load capacitance and 40 Ohm ESR.

Selection between these parts should be based on:

Availability: XC32M4-30.000-F18JJDTK offers the highest inventory level at 33,789 units. The 830059646 (Würth) provides 3,044 units, while ABM8-30.000MHZ-D2Y-T and LFXTAL059646 offer 994 and 923 units respectively.

Packaging Format: LFXTAL059646, 830059646, and XC32M4-30.000-F18JJDTK are supplied in Tape & Reel format. ABM8-30.000MHZ-D2Y-T is available in Cut Tape and Digi-Reel format, which may affect procurement workflows.

Regulatory Compliance: All parts meet ROHS3 and REACH requirements. ECCN classification is EAR99 for all parts except XC32M4-30.000-F18JJDTK, which carries HTSUS code 8541.60.0000 versus 8541.60.0060 for the others.

Moisture Sensitivity: LFXTAL059646, 830059646, and ABM8-30.000MHZ-D2Y-T are not applicable for MSL. XC32M4-30.000-F18JJDTK carries MSL Level 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the LFXTAL059646?

A: Yes. All four parts—LFXTAL059646, 830059646, ABM8-30.000MHZ-D2Y-T, and XC32M4-30.000-F18JJDTK—are parametric equivalents. They share identical frequency, tolerance, load capacitance, ESR, package type, physical dimensions, and operating temperature range. They are electrically and mechanically interchangeable in circuit designs specified for 30 MHz ±20 ppm crystals with 18 pF load capacitance.

Q: What are the critical parameters that determine substitutability?

A: Substitutability is determined by exact matching of: frequency (30.0000 MHz), frequency tolerance (±20 ppm), load capacitance (18 pF), ESR (40 Ohms), package type (4-SMD, No Lead), physical dimensions (3.20 × 2.50 × 0.80 mm), operating temperature range (-40 to +85°C), and operating mode (Fundamental). Deviation in any of these parameters disqualifies a part as a direct substitute.

Q: Are there packaging differences I should consider?

A: Yes. LFXTAL059646, 830059646, and XC32M4-30.000-F18JJDTK are supplied in Tape & Reel (TR) format. ABM8-30.000MHZ-D2Y-T is supplied in Cut Tape (CT) and Digi-Reel® format. Verify your assembly equipment compatibility with the packaging format before selection.

Q: What is the difference in moisture sensitivity between these parts?

A: LFXTAL059646, 830059646, and ABM8-30.000MHZ-D2Y-T have MSL not applicable, indicating no moisture sensitivity restrictions. XC32M4-30.000-F18JJDTK carries MSL Level 1 (Unlimited), which also indicates no practical moisture sensitivity constraints for standard handling and storage.

Q: Which part has the best availability?

A: XC32M4-30.000-F18JJDTK has the highest inventory at 33,789 units. If supply continuity is a priority, this part offers the largest stock buffer. Würth's 830059646 provides the second-highest availability at 3,044 units.

Q: Do all parts meet the same regulatory standards?

A: All four parts are ROHS3 compliant and REACH unaffected. ECCN classification is EAR99 for LFXTAL059646, 830059646, and ABM8-30.000MHZ-D2Y-T. XC32M4-30.000-F18JJDTK carries HTSUS code 8541.60.0000 versus 8541.60.0060 for the others. Verify export classification requirements for your specific application and destination.

Q: Can I mix these parts in the same production batch?

A: Electrically and mechanically, yes. However, verify with your assembly partner regarding any internal traceability, qualification, or documentation requirements that may restrict mixing of different manufacturers in a single production run.
