Substitute Part Grouping Explanation

Substitution of the 830035265 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part LFXTAL035265 from IQD Frequency Products qualifies as a parametric equivalent based on the following criteria:

Electrical Parameter Equivalence: Frequency, frequency stability, load capacitance, and ESR must match exactly. Both parts operate at 20 MHz with ±50ppm stability, 16pF load capacitance, and 50 Ohms ESR.

Mechanical Parameter Equivalence: Operating mode, mounting type, package configuration, and physical dimensions must be identical. Both parts use fundamental mode operation, surface mount technology, 4-SMD No Lead packaging, and identical 3.20mm x 2.50mm dimensions with 0.80mm maximum seated height.

Environmental and Compliance Equivalence: Operating temperature range, RoHS status, and regulatory compliance must align. Both parts operate across -10°C to 60°C, maintain ROHS3 compliance, and share identical REACH and ECCN classifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 830035265 and LFXTAL035265 are Active products with full ROHS3 compliance and identical regulatory classifications (REACH Unaffected, ECCN EAR99). Selection between these parts is based on availability, supply chain requirements, and procurement preferences.

The 830035265 from Würth Elektronik is the primary part with 3103 pieces in current inventory.

Both parts satisfy identical electrical specifications, mechanical constraints, and environmental operating conditions.

Component selection should prioritize availability and lead time requirements. Both parts are suitable for direct substitution in applications requiring a 20 MHz fundamental mode crystal with 16pF load capacitance and 50 Ohms ESR in a compact 4-SMD surface mount package.

Frequently Asked Questions (FAQ)

Q: Can the LFXTAL035265 be used as a direct replacement for the 830035265?

A: Yes. The LFXTAL035265 is a parametric equivalent with identical frequency, frequency stability, load capacitance, ESR, operating temperature range, and physical dimensions. Both parts use the same 4-SMD No Lead package configuration and meet identical compliance requirements.

Q: Are there any differences in the physical footprint between these parts?

A: No. Both parts share identical dimensions of 3.20mm length x 2.50mm width with a maximum seated height of 0.80mm. PCB layout and land pattern requirements are identical.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the 830035265 and LFXTAL035265 operate across -10°C to 60°C. No thermal performance differences exist between the two parts.

Q: What is the significance of the 16pF load capacitance specification?

A: Load capacitance determines the crystal's operating frequency when connected to a specific oscillator circuit. Both parts require 16pF load capacitance for accurate 20 MHz operation. Circuit design must account for this specification.

Q: Are both parts RoHS compliant?

A: Yes. Both the 830035265 and LFXTAL035265 are ROHS3 compliant and REACH unaffected. Both carry identical regulatory classifications.

Q: What does the ±50ppm frequency stability specification mean?

A: Frequency stability of ±50ppm indicates that the crystal's output frequency will not deviate more than 50 parts per million from the nominal 20 MHz specification across the operating temperature range and under specified load conditions.

Q: Can these parts be used interchangeably in production?

A: Yes. Both parts are Active products with identical electrical and mechanical specifications. They can be used interchangeably provided the oscillator circuit is designed for 16pF load capacitance and 50 Ohms ESR.
