Equivalent & Substitute Parts for 830003206B

Part Overview

The Würth Elektronik 830003206B is a 12 MHz quartz crystal oscillator in HC-49/U package configuration, designed for through-hole mounting applications. This component operates at a fundamental frequency with ±20 ppm tolerance and 30 pF load capacitance, suitable for timing and frequency control circuits requiring stable oscillation in the 12 MHz band. The part is currently active in production status with full RoHS3 compliance. Substitute parts are identified to provide alternative sourcing options while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the 830003206B is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following specifications without deviation:

Frequency: 12 MHz (exact match required)
Frequency Tolerance: ±20 ppm (exact match required)
Frequency Stability: ±30 ppm (exact match required)
Load Capacitance: 30 pF (exact match required)
ESR: 35 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: -10°C to 60°C (exact match required)
Physical Dimensions: 0.435" L x 0.183" W, Height 0.530" max (exact match required)

The identified substitute part meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Engineering Selection Recommendations

Both the 830003206B and LFXTAL003206BULK are active production components with full RoHS3 compliance. The parts are electrically and mechanically identical across all specified parameters. Selection between these components may be based on:

Manufacturer availability and lead time
Current inventory levels (830003206B: 958 pcs; LFXTAL003206BULK: 1180 pcs)
Supplier logistics and procurement channels
REACH compliance status (830003206B: REACH Unaffected; LFXTAL003206BULK: REACH Affected)

Both components are classified under ECCN EAR99 and HTSUS 8541.60.0050. The LFXTAL003206BULK carries REACH Affected status, which may require additional documentation in certain regulatory jurisdictions.

Frequently Asked Questions (FAQ)

Q: Can LFXTAL003206BULK be used as a direct replacement for 830003206B in existing circuit designs?

A: Yes. The LFXTAL003206BULK is a parametric equivalent with identical electrical specifications (12 MHz frequency, ±20 ppm tolerance, 30 pF load capacitance, 35 Ohms ESR) and mechanical configuration (HC-49/U package, through-hole mounting, identical physical dimensions). No circuit modifications are required.

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

A: No. Both components share identical dimensions: 0.435" L x 0.183" W (11.05 mm x 4.65 mm) with a maximum seated height of 0.530" (13.46 mm). They are mechanically interchangeable in PCB layouts designed for HC-49/U through-hole crystals.

Q: What is the significance of the ±20 ppm tolerance and ±30 ppm stability specifications?

A: The ±20 ppm frequency tolerance defines the initial accuracy of the crystal at the time of manufacture. The ±30 ppm frequency stability defines the maximum frequency variation over the operating temperature range of -10°C to 60°C. Both specifications are identical between the main part and substitute.

Q: Does the REACH Affected status of LFXTAL003206BULK affect its usability?

A: REACH Affected status indicates the component is subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. This does not affect the component's electrical or mechanical performance. Regulatory compliance requirements depend on the end-use application and destination market.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 830003206B and LFXTAL003206BULK operate across the identical temperature range of -10°C to 60°C with the same frequency stability specification of ±30 ppm.

Q: What is the load capacitance specification and why is it important?

A: Load capacitance of 30 pF specifies the capacitive load that the crystal oscillator circuit must present for the crystal to oscillate at its specified frequency. Both parts require identical 30 pF load capacitance. Mismatched load capacitance will result in frequency deviation from specification.
