Substitute Part Grouping Explanation

Substitute parts for the 830003127B are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain constant across all equivalent parts:

Frequency: 6 MHz (exact match required)
Frequency Tolerance: ±20ppm (exact match required)
Load Capacitance: 30pF (exact match required)
ESR: 100 Ohms (exact match required)
Package / Case: HC-49/U (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -10°C ~ 60°C (exact match required)
Physical Dimensions: 0.435" L x 0.183" W, Height 0.530" max (exact match required)

Parts meeting all these parameters are classified as parametric equivalents and direct functional substitutes. The IQD Frequency Products LFXTAL003127BULK meets all specified electrical and mechanical parameters for direct replacement.

Engineering Selection Recommendations

Both the primary part 830003127B and the substitute LFXTAL003127BULK are classified as Active product status, indicating current manufacturing and availability. Both components are RoHS3 compliant and carry identical ECCN and HTSUS classifications, confirming regulatory alignment.

The LFXTAL003127BULK from IQD Frequency Products provides parametric equivalence across all electrical and mechanical specifications. Selection between these parts may be based on inventory availability, lead time requirements, or supply chain preferences, as both components satisfy identical functional requirements for 6 MHz crystal oscillator applications in HC-49/U through-hole configurations.

Frequently Asked Questions (FAQ)

Q: Can LFXTAL003127BULK be used as a direct replacement for 830003127B?

A: Yes. The LFXTAL003127BULK meets all electrical and mechanical specifications of the 830003127B, including frequency, tolerance, load capacitance, ESR, package type, and operating temperature range. Direct substitution is supported.

Q: Are there any differences in compliance or regulatory status between these parts?

A: Both parts are RoHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8541.60.0050) classifications. The primary difference is REACH status: 830003127B is REACH Unaffected while LFXTAL003127BULK is REACH Affected. Verify REACH compliance requirements for your specific application jurisdiction.

Q: What are the critical parameters that must match for substitution?

A: Frequency (6 MHz), frequency tolerance (±20ppm), load capacitance (30pF), ESR (100 Ohms), package type (HC-49/U), mounting method (through hole), operating temperature range (-10°C ~ 60°C), and physical dimensions must all match exactly.

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

A: No. Both parts are specified for through-hole mounting only. HC-49/U is a through-hole package configuration and is not suitable for surface-mount assembly.

Q: What is the difference between frequency tolerance and frequency stability?

A: Frequency tolerance (±20ppm) specifies the initial accuracy of the crystal at the time of manufacture. Frequency stability (±50ppm) specifies the maximum frequency variation over the operating temperature range and operating life.

Q: Are there inventory considerations when selecting between these parts?

A: The 830003127B has 853 pieces in stock, while LFXTAL003127BULK has 1260 pieces in stock. Selection may depend on immediate availability requirements and supply chain lead times.
