Substitute Part Grouping Explanation

Substitute parts for the HLMP-3301-F00R4 are grouped into two categories based on substitution criteria:

Category 1: Direct Parametric Equivalents (Broadcom HLMP-3301 Series)

Parts HLMP-3301, HLMP-3301-F0001, HLMP-3301-F0002, and HLMP-3301-F00DD are direct parametric equivalents. These parts share identical electrical and optical specifications:

• Voltage - Forward (Vf): 1.9V
• Current - Test: 10mA
• Millicandela Rating: 5.4mcd
• Wavelength - Dominant: 626nm
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole
• Package / Case: Radial

Differences exist only in packaging format (Bulk, Tape & Reel, Cut Tape) and product status (Active vs. Obsolete). All Category 1 parts are ROHS3 compliant.

Category 2: Cross-Manufacturer Substitute (Lite-On LTL-307P)

The LTL-307P from Lite-On Inc. is a cross-manufacturer substitute with compatible mechanical form factor but different electrical and optical characteristics:

• Voltage - Forward (Vf): 2.1V (vs. 1.9V)
• Current - Test: 20mA (vs. 10mA)
• Millicandela Rating: 5.6mcd (vs. 5.4mcd)
• Wavelength - Dominant: 657nm (vs. 626nm)
• Viewing Angle: 50° (vs. 60°)
• Height (Max): 8.60mm (vs. 9.19mm)

The LTL-307P maintains the same lens size (5mm, T-1 3/4), mounting type (Through Hole), and radial package configuration, enabling mechanical interchangeability in through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

Select from the active Broadcom HLMP-3301 series parts (HLMP-3301, HLMP-3301-F0001, HLMP-3301-F0002, HLMP-3301-F00DD) when electrical and optical specifications must remain unchanged. All four parts deliver identical performance with 1.9V forward voltage, 10mA test current, and 626nm dominant wavelength. Selection among these four parts depends on packaging requirements: Bulk for general procurement, Tape & Reel for automated assembly, or Cut Tape for mixed-volume applications. All are ROHS3 compliant, addressing regulatory requirements not met by the obsolete HLMP-3301-F00R4.

For Cross-Manufacturer Substitution:

The Lite-On LTL-307P is suitable only when circuit design accommodates higher forward voltage (2.1V vs. 1.9V), higher test current (20mA vs. 10mA), and different wavelength characteristics (657nm dominant vs. 626nm). The LTL-307P maintains mechanical compatibility through identical lens size and through-hole radial package, but electrical parameter differences require circuit validation. This part is ROHS3 compliant and carries active product status.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3301-F00R4 be replaced with any HLMP-3301 variant without circuit modification?

A: Yes. HLMP-3301, HLMP-3301-F0001, HLMP-3301-F0002, and HLMP-3301-F00DD are parametric equivalents with identical electrical and optical specifications. Differences are limited to packaging format and product status. No circuit modification is required.

Q: What is the difference between HLMP-3301-F0001 (Tape & Reel) and HLMP-3301-F0002 (Cut Tape)?

A: Both parts are electrically and optically identical. The difference is packaging format. Tape & Reel packaging is optimized for high-volume automated assembly. Cut Tape is suitable for lower-volume or mixed-component applications. Select based on assembly process requirements.

Q: Can LTL-307P be used as a direct drop-in replacement?

A: LTL-307P is mechanically compatible but not electrically equivalent. It requires higher forward voltage (2.1V vs. 1.9V) and higher test current (20mA vs. 10mA). Circuit validation is necessary before substitution. The wavelength difference (657nm vs. 626nm) may also affect visual appearance in applications where color consistency is critical.

Q: Why is HLMP-3301-F00R4 listed as obsolete?

A: The HLMP-3301-F00R4 is obsolete, but the base HLMP-3301 series remains active. Active variants with identical specifications are available for new designs and ongoing production support.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts (HLMP-3301, HLMP-3301-F0001, HLMP-3301-F0002, HLMP-3301-F00DD, and LTL-307P) are ROHS3 compliant. The original HLMP-3301-F00R4 is RoHS non-compliant.

Q: What is the inventory status for these parts?

A: HLMP-3301-F00DD has the highest inventory (43,381 pcs), followed by HLMP-3301 (28,097 pcs) and HLMP-3301-F0002 (6,700 pcs). HLMP-3301-F0001 has 1,038 pcs, and LTL-307P has 2,769 pcs available.
