HLMP1300 Red Diffused T-1 LED Equivalent & Substitute Parts

Part Overview

The HLMP1300 is a red diffused T-1 through-hole LED manufactured by onsemi, rated at 2V forward voltage with 2mcd brightness and a 90° viewing angle. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. The HLMP1300 remains available in inventory (961 pcs), but active alternatives from current manufacturers provide design flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitution for the HLMP1300 is determined by the following critical parameters:

Mechanical Compatibility: Lens size (3mm T-1), lens style (round with domed top), mounting type (through hole radial), and physical height must match or be compatible with the original design footprint.

Electrical Compatibility: Forward voltage (Vf) tolerance, test current rating, and wavelength characteristics must support the intended circuit application. The HLMP1300 operates at 2V with 10mA test current and 635nm peak wavelength.

Optical Performance: Lens transparency (diffused), color (red), and viewing angle determine visibility characteristics. The HLMP1300 provides a wide 90° viewing angle.

Regulatory & Supply Status: Active product status and RoHS3 compliance ensure long-term availability and regulatory alignment. Obsolete status of the HLMP1300 necessitates transition to active alternatives.

Substitute parts are grouped into two categories:

Category A - Direct Mechanical & Electrical Equivalents: Parts with T-1 3mm form factor, 2V or near-2V forward voltage, and similar test current specifications (3HD-F, 3RD-F, 3SRD-F, 3SRD-S, HLMP-1301-G00FG).

Category B - Form Factor Equivalents with Voltage Variation: Parts with T-1 3mm form factor but different forward voltage ratings (151031SS06000 at 2.2V, 4300F1LC at 1.8V, HLMP-1600 at 5V).

Engineering Selection Recommendations

For Direct Replacement (Preferred):

The 3HD-F (Bivar Inc.) is the closest direct equivalent, matching the HLMP1300 at 2V forward voltage with T-1 3mm form factor and through-hole radial mounting. It is active product status with ROHS3 compliance. The 3HD-F operates at 20mA test current (versus 10mA for HLMP1300) and provides 30mcd brightness with a 35° viewing angle, representing a narrower field of view than the original 90°.

The HLMP-1301-G00FG (Broadcom Limited) provides active product status with 1.9V forward voltage, 10mA test current matching the HLMP1300, and identical T-1 3mm form factor. It delivers 8.6mcd brightness with 60° viewing angle and ROHS3 compliance.

For Voltage-Constrained Applications:

The 3SRD-F and 3SRD-S (Bivar Inc.) operate at 1.7V forward voltage with 20mA test current, suitable for lower-voltage circuit designs. Both maintain T-1 3mm form factor and radial through-hole mounting with ROHS3 compliance. The 3SRD-S provides slightly increased height tolerance (4.50mm versus 5.30mm).

The 151031SS06000 (Würth Elektronik) operates at 2.2V forward voltage with 20mA test current, offering active product status and ROHS3 compliance in the WL-TMRC series. It maintains T-1 3mm form factor with 5.55mm maximum height.

For High-Voltage Applications:

The HLMP-1600 (Broadcom Limited) operates at 5V forward voltage with 10mA test current, designed for direct 5V circuit integration. It maintains T-1 3mm form factor, radial through-hole mounting, and ROHS3 compliance with 2.1mcd brightness and 60° viewing angle.

Status Considerations:

The 4300F1LC (Visual Communications Company - VCC) carries "Not For New Designs" status despite active inventory. This part operates at 1.8V forward voltage with 2mA test current and should be avoided for new product development.

All recommended substitutes carry active product status or ROHS3 compliance, ensuring regulatory alignment and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 3HD-F directly replace the HLMP1300 in existing designs?

A: The 3HD-F shares the same 2V forward voltage, T-1 3mm form factor, and radial through-hole mounting as the HLMP1300. However, it operates at 20mA test current (versus 10mA) and provides a narrower 35° viewing angle compared to the HLMP1300's 90° viewing angle. Circuit redesign may be required to accommodate the higher test current and reduced field of view.

Q: What is the primary difference between the 3SRD-F and 3SRD-S?

A: Both parts operate at identical 1.7V forward voltage, 20mA test current, and 40mcd brightness with T-1 3mm form factor. The 3SRD-S has a reduced maximum height of 4.50mm compared to 3SRD-F at 5.30mm, and provides a slightly wider 40° viewing angle versus 35°.

Q: Is the HLMP-1600 suitable as a substitute for the HLMP1300?

A: The HLMP-1600 maintains the same T-1 3mm form factor and radial through-hole mounting but operates at 5V forward voltage, requiring significant circuit redesign. It is suitable only for applications where 5V operation is acceptable and the circuit can be modified accordingly.

Q: Why does the 151031SS06000 have higher brightness (35mcd) than the HLMP1300 (2mcd)?

A: The 151031SS06000 is designed for higher-brightness indication applications. While it maintains compatible form factor and mounting, the increased brightness may require circuit current limiting adjustments. Verify that the application can accommodate the higher luminous intensity.

Q: What is the viewing angle impact when substituting the HLMP1300?

A: The HLMP1300 provides a wide 90° viewing angle. Most active substitutes (3HD-F, 3RD-F, 3SRD-F, 3SRD-S) offer narrower 35-40° viewing angles. The 151031SS06000 and HLMP-1301-G00FG provide 60° viewing angles. Application visibility requirements must be evaluated against the substitute's optical characteristics.

Q: Are all substitute parts RoHS3 compliant?

A: All recommended active substitute parts carry ROHS3 compliance certification. The original HLMP1300 does not specify RoHS status. Compliance verification is recommended for regulated applications.

Q: Can the 4300F1LC be used in new designs?

A: The 4300F1LC carries "Not For New Designs" product status. It should not be selected for new product development. Active alternatives with current product status are available.

Q: What forward voltage range is acceptable for HLMP1300 substitution?

A: The HLMP1300 operates at 2V forward voltage. Acceptable substitutes range from 1.7V to 2.2V for direct circuit compatibility without major redesign. The 5V HLMP-1600 requires complete circuit modification and is suitable only for voltage-flexible applications.
