Parameter Comparison

Engineering Selection Recommendations

Both the 5500812F and 5500805F are active Dialight 550 series products with identical electrical and optical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. The 5500805F offers higher inventory availability (2960 pcs versus 835 pcs), which may provide supply chain advantages for high-volume applications. Both parts maintain full ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. No performance differentiation exists between these parts for the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5500805F replace the 5500812F in existing designs? A: Yes. Both parts share identical electrical ratings (5V, 10mA), optical characteristics (583nm peak wavelength, 8mcd, 60° viewing angle), lens type (diffused), and mounting configuration (through-hole, right-angle). No circuit modifications are required.

Q: Are there any compliance differences between these parts? A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level). Regulatory status is identical.

Q: What is the primary reason to consider substitution? A: Inventory availability. The 5500805F maintains significantly higher stock levels (2960 pcs) compared to the 5500812F (835 pcs), providing supply chain flexibility for production planning.

Q: Do these parts have different packaging specifications? A: Both parts are supplied in bulk packaging. No packaging differentiation is specified in the provided parameters.

Q: Are the optical outputs identical? A: Yes. Both parts deliver 8mcd brightness at 583nm peak wavelength with a 60° viewing angle and diffused lens type. Optical performance is equivalent.
