Key Parameters

Substitute Part Grouping Explanation

Substitution for the Dialight 5855513 is determined by the following critical parameters: base type (Miniature Bayonet BA9S), form factor (T-3 1/4), color (Yellow), wavelength (592nm), and forward voltage (14V). Parts meeting these specifications are direct functional equivalents. A parametric equivalent exists with differing forward voltage (6V), which requires circuit redesign but maintains identical mechanical and optical characteristics.

The substitute parts are grouped as follows:

Direct Equivalents (Same Voltage): Parts maintaining 14V forward voltage with identical base type, form factor, wavelength, and color.

Parametric Equivalents (Different Voltage): Parts with 6V forward voltage, requiring voltage supply modification but preserving all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification): Select Dialight 5855513F or 5855523F. Both parts are active products with ROHS3 compliance, providing regulatory advantage over the obsolete 5855513. These parts maintain identical 14V forward voltage, eliminating the need for power supply redesign. Dialight 5855513F is available in bulk packaging with 996 units in stock. Dialight 5855523F is also available in bulk packaging with 640 units in stock.

For Voltage-Flexible Applications: Dialight 5855511F serves as a parametric equivalent for systems capable of operating at 6V. This part is active with ROHS3 compliance and maintains all mechanical and optical specifications. Selection of this part requires verification that the circuit power supply can be modified to 6V operation.

All substitute parts carry ROHS3 compliance, addressing regulatory requirements absent in the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can 5855513F directly replace 5855513 without any modifications? A: Yes. The 5855513F maintains identical electrical specifications (14V forward voltage), base type (BA9S), form factor (T-3 1/4), color (Yellow), and optical output (1800mcd at 592nm). Direct socket substitution is possible without circuit modification.

Q: What is the difference between 5855513F and 5855523F? A: Both parts are direct equivalents with identical electrical and optical parameters. The primary difference is product designation and packaging availability. Both operate at 14V and deliver 1800mcd at 592nm wavelength.

Q: Can 5855511F be used as a substitute? A: 5855511F is a parametric equivalent with differing forward voltage (6V instead of 14V). Substitution requires circuit redesign to accommodate the lower voltage supply. All other parameters—base type, form factor, color, and optical output—remain identical.

Q: Why is the original 5855513 marked as obsolete? A: The original part is classified as obsolete. Active alternatives (5855513F, 5855523F, 5855511F) are available from Dialight with improved compliance status (ROHS3).

Q: What packaging options are available for these substitutes? A: All substitute parts are available in bulk packaging. Inventory levels are: 5855513F (996 units), 5855523F (640 units), and 5855511F (1000 units).

Q: Are all substitute parts RoHS compliant? A: Yes. All substitute parts (5855513F, 5855523F, 5855511F) are ROHS3 compliant, whereas the original 5855513 is RoHS non-compliant.
