Dialight 5500512F LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The Dialight 5500512F is an LED Circuit Board Indicator designed for 5V applications. This single red diffused LED features a 5mm T-1 3/4 form factor with right-angle through-hole mounting. The component is classified as Active product status and is ROHS3 compliant. Substitute parts become necessary when the primary part number experiences supply constraints, extended lead times, or inventory depletion, while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The substitute parts 5500505F and 5500507F are direct equivalents to the 5500512F based on matching electrical and mechanical parameters. Substitution is valid when all of the following criteria are met:

• Identical voltage rating (5V)
• Identical current rating (13mA)
• Identical wavelength peak (655nm)
• Identical millicandela rating (2mcd)
• Identical viewing angle (60°)
• Identical lens type (Diffused)
• Identical lens style (Round with Domed Top)
• Identical lens size (5mm, T-1 3/4)
• Identical mounting type (Through Hole, Right Angle)
• Identical RoHS compliance status (ROHS3 Compliant)
• Identical moisture sensitivity level (MSL 1)

All three part numbers meet these criteria and belong to the Dialight 550 series. They are functionally interchangeable in circuit board indicator applications requiring 5V red LED indicators with diffused optics.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers are Active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Selection between 5500512F, 5500505F, and 5500507F should be based on inventory availability and lead time requirements. The 5500505F offers the highest current inventory level at 2251 pieces, followed by 5500507F at 1117 pieces, and 5500512F at 870 pieces. From a compliance perspective, all parts are equivalent and suitable for direct substitution in applications requiring 5V red LED circuit board indicators with diffused optics and right-angle through-hole mounting.

Frequently Asked Questions (FAQ)

Q: Can 5500505F and 5500507F be used interchangeably with 5500512F?

A: Yes. All three part numbers share identical electrical specifications (5V, 13mA, 655nm peak wavelength, 2mcd), mechanical form factors (5mm T-1 3/4 diffused lens, round with domed top), and mounting configuration (through hole, right angle). They are direct substitutes within the Dialight 550 series.

Q: What parameters determine substitution eligibility?

A: Substitution is valid when voltage rating, current rating, wavelength, millicandela rating, viewing angle, lens type, lens style, lens size, mounting type, and compliance certifications (RoHS, REACH, MSL) are identical. All three parts meet these criteria.

Q: Are there any differences in packaging or handling?

A: All three parts are supplied in bulk packaging with identical moisture sensitivity level (MSL 1, Unlimited), indicating no special storage or handling requirements beyond standard component practices.

Q: Which part should be selected for new designs?

A: Any of the three part numbers are suitable for new designs. Selection should consider current inventory levels and supplier lead times. The 5500505F provides the highest stock availability.

Q: Do these parts require different circuit design considerations?

A: No. The identical electrical and optical specifications mean no circuit modifications are required when substituting between 5500512F, 5500505F, and 5500507F.
