Parameter Comparison

Engineering Selection Recommendations

Both the 5510001876F and 5510301F are active Dialight products within the 551 series, carrying identical ROHS3 and REACH compliance certifications. Selection between these parts should be based on circuit board design requirements and viewing angle specifications. The 5510301F provides a defined 60° viewing angle, while the 5510001876F does not specify this parameter. Both components meet unlimited moisture sensitivity requirements (MSL 1) and are suitable for standard industrial circuit board applications without environmental restrictions.

Frequently Asked Questions (FAQ)

Q: Can the 5510301F directly replace the 5510001876F in existing designs?

A: Yes. Both parts share identical electrical ratings (2.1V, 20mA, 10mcd), physical form factor (3mm T-1 through-hole right-angle), lens characteristics (diffused, tinted, round domed top), and compliance certifications (ROHS3, REACH Unaffected). The primary difference is the specified 60° viewing angle on the 5510301F. Verify that your circuit board layout and optical requirements are compatible with this viewing angle specification.

Q: What is the significance of the viewing angle difference?

A: The 5510301F specifies a 60° viewing angle, while the 5510001876F does not provide this specification. Viewing angle determines the cone of light distribution from the LED. If your application requires a specific viewing angle for indicator visibility, confirm compatibility before substitution.

Q: Are both parts available in the same packaging?

A: Yes. Both the 5510001876F and 5510301F are supplied in bulk packaging as standard through-hole components.

Q: Do these parts have any environmental or storage restrictions?

A: No. Both parts carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity limitations during storage or handling. Standard component storage practices apply.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for industrial and commercial applications.
