Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 830003037B are identified through parametric equivalence matching. The substitution criteria are based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Frequency: 2 MHz (exact match required)
• Frequency Tolerance: ±50ppm (exact match required)
• Load Capacitance: 20pF (exact match required)
• ESR: 600 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Package / Case: HC-49/U (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: 0°C to 50°C (exact match required)

Parts meeting all critical parameters are classified as parametric equivalents and direct substitutes. Physical dimensions, compliance certifications, and inventory availability are secondary considerations that do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the 830003037B and LFXTAL003037BULK are active production parts with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

Availability and Lead Time: The LFXTAL003037BULK offers higher inventory availability at 1280 units compared to 864 units for the 830003037B, providing supply chain flexibility for high-volume applications.

Compliance and Regulatory Status: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. The LFXTAL003037BULK is REACH Affected, while the 830003037B is REACH Unaffected. Applications subject to REACH regulations should reference the specific regulatory requirements of the end-use jurisdiction.

Manufacturer Selection: The choice between Würth Elektronik and IQD Frequency Products depends on existing supply chain relationships, qualification requirements, and procurement policies. Both manufacturers produce crystals meeting identical parametric specifications for this frequency and package type.

Direct Substitution: The LFXTAL003037BULK is a direct parametric equivalent suitable for pin-for-pin and functional replacement in all applications currently using the 830003037B without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the LFXTAL003037BULK replace the 830003037B in existing designs?

A: Yes. The LFXTAL003037BULK is a parametric equivalent with identical frequency, tolerance, load capacitance, ESR, operating mode, package, and temperature range. Direct substitution is supported without circuit changes.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions of 0.435" L x 0.183" W (11.05mm x 4.65mm) with a maximum seated height of 0.530" (13.46mm). PCB footprints and mechanical clearances are interchangeable.

Q: What is the difference in REACH compliance status?

A: The 830003037B is REACH Unaffected, while the LFXTAL003037BULK is REACH Affected. Applications requiring REACH compliance should confirm regulatory applicability with legal or compliance departments before part selection.

Q: Are both parts RoHS compliant?

A: Yes. Both the 830003037B and LFXTAL003037BULK are ROHS3 compliant and suitable for applications with RoHS requirements.

Q: What is the operating temperature range for these crystals?

A: Both parts operate across 0°C to 50°C. Applications requiring extended temperature ranges outside this specification require alternative part selection.

Q: Is the 2 MHz frequency tolerance of ±50ppm suitable for my application?

A: The ±50ppm frequency tolerance specification is provided for both parts. Application suitability depends on the specific frequency accuracy requirements of the circuit design. Confirm tolerance requirements against circuit specifications before implementation.

Q: Can these through-hole crystals be used in surface-mount applications?

A: No. Both parts are through-hole mounted components designed for PCB insertion into drilled holes. Surface-mount crystal alternatives require separate part selection.
