Key Parameters

Substitute Part Grouping Explanation

The Dialight 5501007F qualifies as a direct substitute based on the following critical parameters:

• Color and Configuration: Both parts are single blue LEDs with clear lenses
• Electrical Specifications: Identical current rating (20mA) and voltage rating (3.8V)
• Mounting Architecture: Both feature through-hole, right-angle mounting compatible with identical PCB layouts
• Reliability Classification: Both maintain MSL 1 (Unlimited) moisture sensitivity rating
• Regulatory Compliance: Both are REACH Unaffected and classified as EAR99

The primary distinction is product status: the 5501007 is Obsolete, while the 5501007F is Active and RoHS3 Compliant, making it the recommended active equivalent for new designs and replenishment.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5501007F is the direct active equivalent for the obsolete 5501007. Selection criteria are based on the following factors:

• Product Status: The 5501007F is Active and currently manufactured, ensuring supply chain continuity and long-term availability
• Regulatory Compliance: RoHS3 Compliance of the 5501007F meets current environmental and material restriction requirements
• Electrical Equivalence: Identical voltage (3.8V) and current (20mA) specifications ensure drop-in compatibility in existing circuit designs
• Mechanical Compatibility: Matching through-hole, right-angle mounting and 5mm form factor allow direct PCB substitution without layout modifications
• Brightness Performance: The 1000mcd rating of the 5501007F is within acceptable tolerance of the 1010mcd original specification

Frequently Asked Questions (FAQ)

Q: Can the 5501007F be used as a direct replacement for the 5501007 in existing designs?

A: Yes. Both parts share identical electrical specifications (3.8V, 20mA), mounting configuration (through-hole, right-angle), and lens characteristics (5mm clear blue). PCB layouts and circuit designs require no modification.

Q: What is the brightness difference between the two parts?

A: The 5501007 is rated at 1010mcd while the 5501007F is rated at 1000mcd. This 10mcd difference represents less than 1% variance and is within acceptable tolerance for indicator applications.

Q: Why is the 5501007 classified as Obsolete?

A: The 5501007 has been superseded by the 5501007F, which offers improved regulatory compliance (RoHS3) and active manufacturing status. Dialight continues to support the 550 series through the active 5501007F variant.

Q: Are there packaging differences between these parts?

A: The 5501007 is specified with "-" packaging notation, while the 5501007F is supplied in Bulk packaging. Both are suitable for through-hole assembly processes.

Q: Do both parts meet the same moisture sensitivity requirements?

A: Yes. Both the 5501007 and 5501007F are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Is the 5501007F RoHS compliant?

A: Yes. The 5501007F is RoHS3 Compliant, meeting current European Union Restriction of Hazardous Substances requirements. The original 5501007 RoHS status is not specified in available documentation.
