Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5RDL-F is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Color: Red
• Lens Transparency: Diffused
• Lens Size: 5mm, T-1 3/4
• Voltage - Forward (Vf): 2.1V
• Mounting Type: Through Hole
• Package / Case: Radial
• Wavelength - Peak: 700nm
• Viewing Angle: 40°
• Height (Max): 8.60mm

Allowable Variation Parameters:

• Millicandela Rating: May vary based on application requirements
• Current - Test: May vary based on circuit design
• Product Status: Active status preferred for new procurement
• Lens Color: May differ from diffused appearance
• Packaging Format: Bulk or tape formats acceptable

The substitute part 5RD-F meets all mandatory matching parameters while offering improved availability through active product status and alternative packaging options.

Parameter Comparison

Engineering Selection Recommendations

5RD-F Substitution Basis:

The 5RD-F is a direct functional equivalent to the 5RDL-F for through-hole red LED indication applications. Both components share identical forward voltage (2.1V), optical wavelength (700nm), viewing angle (40°), and mechanical form factor (5mm T-1 3/4 radial package).

Primary Advantages of 5RD-F:

• Active product status ensures long-term availability and supply chain continuity
• RoHS3 compliance certification provides regulatory alignment for current manufacturing standards
• Higher millicandela rating (1.5mcd vs. 0.5mcd) offers improved luminous intensity for visibility-critical applications
• Bulk packaging option reduces per-unit cost for volume procurement

Compatibility Considerations:

• The 5RD-F operates at 20mA test current compared to 5RDL-F at 2mA; circuit design must accommodate this parameter difference
• Identical mechanical dimensions and electrical characteristics ensure direct PCB footprint compatibility
• Both components maintain MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard storage and handling conditions

Regulatory Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 5RD-F directly replace the 5RDL-F in existing designs?

A: Yes, for applications where the 2.1V forward voltage and 40° viewing angle are specified. The identical mechanical form factor (5mm T-1 3/4) and radial package ensure direct PCB compatibility. Circuit design must account for the 20mA test current specification of the 5RD-F.

Q: What is the significance of the millicandela rating difference (0.5mcd vs. 1.5mcd)?

A: The 5RD-F provides three times greater luminous intensity. This variation is allowable for substitution purposes; however, circuit designers must verify that the increased brightness meets application requirements without causing over-illumination or excessive power consumption.

Q: Why is the 5RD-F preferred despite the 5RDL-F being the original specification?

A: The 5RDL-F is classified as obsolete, creating procurement risk. The 5RD-F maintains active product status, ensuring availability for new orders and long-term supply chain support. Both components are manufactured by Bivar Inc. and share identical critical electrical and optical parameters.

Q: Are there packaging differences between these parts?

A: The 5RLF-F is supplied in standard packaging format, while the 5RD-F is available in bulk packaging. Both use identical T-1 3/4 radial component geometry. Packaging format does not affect electrical or mechanical performance.

Q: What compliance certifications apply to both parts?

A: Both the 5RDL-F and 5RD-F carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The 5RD-F additionally carries RoHS3 compliance certification, meeting current environmental regulatory requirements.

Q: Can the 5RD-F be used in applications requiring the exact 0.5mcd brightness specification?

A: No. The 5RD-F provides 1.5mcd brightness, which exceeds the 0.5mcd specification. Applications with strict brightness limitations must evaluate whether the increased intensity is acceptable or if alternative components are required.

Q: Are the electrical characteristics identical between these parts?

A: The forward voltage (2.1V) and wavelength (700nm) are identical. The test current differs: 5RDL-F operates at 2mA while 5RD-F operates at 20mA. Circuit design must accommodate this difference through appropriate current-limiting resistor selection.
