Dialight 5501312F LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The Dialight 5501312F is an LED Circuit Board Indicator designed for low-current applications. This single green diffused LED operates at 1.8V with a 2mA current draw, featuring a 5mm T-1 3/4 through-hole right-angle mounting configuration. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when identical electrical and mechanical parameters are maintained across the same product series, ensuring direct functional equivalence in circuit board applications.

Key Parameters

Substitute Part Grouping Explanation

The Dialight 5501305F qualifies as a direct substitute for the 5501312F based on strict parameter equivalence. Both parts maintain identical electrical specifications: 1.8V voltage rating, 2mA current draw, 1.8mcd brightness output, and 565nm peak wavelength. Mechanical compatibility is preserved through matching lens configuration (5mm T-1 3/4 diffused round with domed top), viewing angle (50°), and through-hole right-angle mounting. Both parts belong to the Dialight 550 series and carry equivalent compliance certifications (RoHS3, REACH Unaffected, MSL 1). Substitution is valid when these core parameters remain unchanged in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the 5501312F and 5501305F are active production parts with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on inventory availability and procurement lead times rather than technical differentiation. The 5501305F currently maintains higher inventory levels (2319 pcs vs. 686 pcs), making it suitable for high-volume production requirements. Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications for export and tariff purposes. MSL 1 rating indicates unlimited shelf life under standard storage conditions for both variants.

Frequently Asked Questions (FAQ)

Q: Can the 5501305F directly replace the 5501312F in existing circuit designs? A: Yes. Both parts share identical electrical ratings (1.8V, 2mA), optical output (1.8mcd, 565nm), and mechanical form factor (5mm T-1 3/4 through-hole right-angle). No circuit modifications are required.

Q: Are there differences in lens diffusion or viewing characteristics? A: No. Both parts feature identical diffused lens construction with round domed top geometry and 50° viewing angle.

Q: What is the significance of the different part numbers (5501312F vs. 5501305F)? A: The part numbers reflect different internal product designations within the Dialight 550 series, but the electrical and mechanical specifications remain equivalent for substitution purposes.

Q: Do both parts meet the same compliance requirements? A: Yes. Both are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.

Q: Which part should be selected for new designs? A: Selection should be based on current inventory availability and supply chain requirements. Both parts are active production items with identical performance characteristics.

Q: Are there packaging differences between these parts? A: Both parts are supplied in bulk packaging. No special handling or storage differences apply.
