Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5501307 are identified based on the following core electrical and mechanical parameters:

Primary Matching Criteria:

• Color: Green
• Configuration: Single LED
• Lens Type: Diffused
• Lens Size: 5mm or T-1 3/4 equivalent
• Mounting Type: Through Hole, Right Angle
• Wavelength Range: 565-568nm

Allowable Parameter Variations:

• Voltage Rating: 1.8V to 2.2V (within typical LED forward voltage tolerance)
• Current Rating: 2mA to 20mA (application-dependent; higher current ratings require circuit adjustment)
• Millicandela Rating: 1.8mcd to 30mcd (brightness variation acceptable for indicator applications)
• Viewing Angle: 45° to 60° (minor variation acceptable for diffused indicators)

The three substitute parts listed below meet the primary matching criteria and represent active or available alternatives to the obsolete 5501307.

Parameter Comparison

Engineering Selection Recommendations

5501307F (Dialight) - Direct Substitute

The 5501307F is the primary recommended substitute. It is manufactured by Dialight, the original manufacturer of the 5501307, and maintains identical electrical specifications (1.8V, 2mA, 1.8mcd). The part is listed as active with ROHS3 compliance and unlimited moisture sensitivity rating. This part provides direct functional equivalence with no circuit modifications required. Packaging is supplied in bulk format.

H178CGDL (Bivar Inc.) - Compatible Substitute

The H178CGDL is an active alternative from Bivar Inc. with compatible electrical and mechanical characteristics. The voltage rating increases to 2.1V and brightness increases to 5mcd, with a slightly narrower viewing angle of 45°. This part is suitable for applications where the increased brightness and voltage tolerance are acceptable. ROHS3 compliance and unlimited moisture sensitivity are confirmed. Packaging is supplied in tray format.

SSF-LXH100LGD-01 (Lumex Opto/Components Inc.) - Higher Performance Substitute

The SSF-LXH100LGD-01 is an active alternative with higher current (20mA) and brightness (30mcd) ratings. This part requires circuit modification to accommodate the increased current demand and 2.2V forward voltage. The tinted diffused lens and 60° viewing angle provide enhanced visibility. ROHS3 compliance and unlimited moisture sensitivity are confirmed. This option is suitable only for applications where the higher performance characteristics are required and circuit design can be adjusted accordingly.

Frequently Asked Questions (FAQ)

Q: Can the 5501307F be used as a direct replacement for the 5501307?

A: Yes. The 5501307F maintains identical electrical specifications (1.8V, 2mA, 1.8mcd) and mechanical mounting configuration. No circuit modifications are required for direct substitution.

Q: What are the key differences between the H178CGDL and the original 5501307?

A: The H178CGDL operates at 2.1V (compared to 1.8V) and provides 5mcd brightness (compared to 1.8mcd). The viewing angle is 45° versus 50°. These differences are within acceptable tolerance for indicator applications, though circuit voltage supply must accommodate the higher forward voltage.

Q: When should the SSF-LXH100LGD-01 be selected?

A: The SSF-LXH100LGD-01 should be selected only when higher brightness (30mcd) and wider viewing angle (60°) are required. This part operates at 20mA, requiring circuit redesign to limit current appropriately. It is not a direct drop-in replacement.

Q: Are all substitute parts RoHS compliant?

A: The 5501307F, H178CGDL, and SSF-LXH100LGD-01 are all ROHS3 compliant. The original 5501307 RoHS status is not specified in available documentation.

Q: What is the moisture sensitivity level for these parts?

A: All listed parts, including the main part and all substitutes, have a Moisture Sensitivity Level of 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Can packaging format affect part selection?

A: Packaging format (bulk, tray, or tape) does not affect electrical or mechanical compatibility. Selection should be based on procurement and assembly process requirements. The 5501307F is available in bulk, H178CGDL in tray, and SSF-LXH100LGD-01 in bulk format.
