Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the DG5305S is based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Lens size: 5mm, T-1 3/4 form factor
• Mounting type: Through-hole radial configuration
• Color: Green wavelength family (522nm to 575nm range)
• Lens style: Round with domed top, clear transparency
• Package / Case: Radial

Secondary Compatibility Considerations:

• Forward voltage (Vf): Range 2.1V to 3.5V (circuit design dependent)
• Brightness (mcd): 60mcd to 980mcd (application dependent)
• Viewing angle: 16° to 30° (application dependent)
• Product status: Active status preferred for long-term availability

The substitute parts listed below maintain the core mechanical and optical form factor while offering variations in electrical performance and brightness characteristics. Selection depends on specific circuit voltage requirements and brightness specifications of the target application.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compatibility):

LTL2P3KGKNN (Lite-On Inc.) is the preferred substitute for applications requiring high brightness. This part maintains the 5mm T-1 3/4 form factor, clear domed lens, and through-hole radial mounting. Operating at 2.1V forward voltage with 980mcd brightness and 20mA test current, it provides superior luminous intensity compared to the DG5305S. The 22° viewing angle and 572nm dominant wavelength remain within the green spectrum. ROHS3 compliance and active product status ensure long-term availability and regulatory compliance.

LTL-4238 (Lite-On Inc.) serves applications where lower brightness is acceptable. This part shares the identical 5mm T-1 3/4 mechanical form factor with clear domed lens and through-hole radial mounting. Operating at 2.1V forward voltage with 90mcd brightness and 10mA test current, it provides a lower-power alternative. The 16° viewing angle and 569nm dominant wavelength maintain green color specification. ROHS3 compliance and active status support long-term design continuity.

5219201F (Dialight) is suitable for incandescent lamp replacement applications. This part operates at 2.1V forward voltage with 60mcd brightness, designed specifically for midget flange base lamp replacement. The T-1 3/4 form factor and through-hole radial mounting maintain mechanical compatibility. ROHS3 compliance and active status provide regulatory support.

Secondary Substitutes (Obsolete Status or Limited Data):

MV3450 (onsemi) is an obsolete alternative with 2.2V forward voltage and 150mcd brightness. While mechanically compatible with the 5mm T-1 3/4 form factor and through-hole radial mounting, its obsolete status limits long-term availability.

5219201 (Dialight) provides a basic 5mm through-hole radial option with active status, though detailed electrical specifications are not provided in the available data.

SSL-LX50595UPGC125 (Lumex Opto/Components Inc.) operates at 525nm wavelength, matching the DG5305S dominant wavelength precisely. Active product status and ROHS3 compliance support regulatory requirements, though complete mechanical specifications are not fully documented.

Frequently Asked Questions (FAQ)

Q: Can LTL2P3KGKNN directly replace DG5305S in existing circuits?

A: Direct replacement requires circuit voltage adjustment. The DG5305S operates at 3.5V forward voltage, while LTL2P3KGKNN operates at 2.1V. The series resistor value must be recalculated to accommodate the lower forward voltage while maintaining 20mA test current. The mechanical form factor (5mm T-1 3/4 through-hole radial) is identical, enabling direct PCB mounting.

Q: What is the brightness difference between DG5305S and substitute parts?

A: DG5305S provides 800mcd brightness. LTL2P3KGKNN offers 980mcd (higher brightness), LTL-4238 provides 90mcd (lower brightness), and 5219201F delivers 60mcd (significantly lower). Selection depends on application visibility requirements and power budget constraints.

Q: Are all substitute parts RoHS3 compliant?

A: LTL2P3KGKNN, LTL-4238, 5219201F, and SSL-LX50595UPGC125 are confirmed ROHS3 compliant. MV3450 and 5219201 compliance status is not documented in available data. For applications requiring RoHS3 certification, use only parts with documented ROHS3 compliance.

Q: What is the wavelength difference between substitute parts?

A: DG5305S operates at 525nm dominant wavelength (522nm peak). Substitute parts vary: LTL2P3KGKNN at 572nm dominant (575nm peak), LTL-4238 at 569nm dominant (565nm peak), 5219201F at 565nm peak, MV3450 at 565nm peak, and SSL-LX50595UPGC125 at 525nm. All remain within the green spectrum; visual color perception differences may occur depending on application context.

Q: Which substitute offers the closest electrical match to DG5305S?

A: No substitute provides identical electrical specifications. LTL2P3KGKNN matches the 20mA test current but operates at 2.1V instead of 3.5V. For applications sensitive to forward voltage, circuit redesign is necessary. For brightness-critical applications, LTL2P3KGKNN (980mcd) provides the closest high-brightness match.

Q: Can I use 5219201 or 5219201F without knowing complete specifications?

A: 5219201 lacks detailed electrical specifications in available documentation, limiting its suitability for new designs. 5219201F is specifically designed for incandescent lamp replacement and operates at 2.1V with 60mcd brightness, suitable only for applications accepting lower brightness levels.

Q: What is the viewing angle impact when substituting?

A: DG5305S provides 30° viewing angle. Substitutes range from 16° (LTL-4238) to 24° (MV3450). Narrower viewing angles concentrate light intensity but reduce peripheral visibility. Application requirements determine acceptable viewing angle range.

Q: Are all substitutes available in the same packaging?

A: All listed substitutes use through-hole radial mounting with 5mm T-1 3/4 form factor, enabling direct PCB mounting. Packaging format (bulk) is consistent across active parts. Height variations range from 7.80mm (DG5305S) to 8.89mm (MV3450), which may affect clearance in space-constrained designs.
