3mm Special-shaped Through-hole LEDs Uses a two-lead specialty-shaped package. This page provides two complete part numbers: red HC-34U22R33CJT-AA-L and white HC-34LU22W15BMW-AA-L. The red version has a clear red encapsulant; the white version's datasheet specifies a white diffused encapsulant. Nominal size is 3mm. Refer to each part number's datasheet for actual outline, mounting dimensions and electrical parameters.
Q: Can the lead length of through-hole LEDs be customized?
A: The available dimensional information specifies a lead length of 29.5±0.5mm. Custom lead trimming, bending and tape packaging remain to be confirmed for this product. Confirm processing requirements using the full model number before ordering.

Ordering and Inquiry Information
Please quote the complete model number and suffix, and specify quantity, test current, brightness binning and structural requirements. PDFs can be downloaded without completing inquiry information. Verify nominal product dimensions separately from actual body dimensions and lead length. The minimum order quantity, sample lead time and volume production lead time remain to be confirmed for this product.
Selection Recommendations
Encapsulant appearance does not indicate emission color. Check current, voltage and pinout for the specific part number when selecting a product. Resolve documentation conflicts against the original manufacturer's drawings before proceeding; do not fill in values from similar models. Current drawings do not provide a one-to-one mapping between physical leads and positive/negative polarity. Supplement the information using original manufacturer drawings or confirm with samples; do not determine polarity solely from lead length.
