LED RED DIFFUSED T-1 3/4 T/H 4302H1-12V Equivalent & Substitute Parts

Part Overview

The 4302H1-12V is an active red LED indication component manufactured by Visual Communications Company (VCC) in T-1 3/4 (5mm) through-hole package configuration. This discrete radial LED operates at 12V forward voltage with 8mcd luminous intensity and diffused lens transparency. The component is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent mechanical packaging, mounting type, and core optical characteristics align with application requirements while accommodating different voltage and current specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 4302H1-12V are identified based on strict alignment of the following mechanical and optical parameters:

Mandatory Matching Parameters:

• Lens Size: 5mm, T-1 3/4
• Lens Style: Round with Domed Top
• Mounting Type: Through Hole
• Package Configuration: Radial
• Color: Red
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant

Variable Parameters (Allowable Differences):

• Voltage - Forward (Vf): Different voltage ratings permitted based on circuit design requirements
• Current - Test: Varies with voltage specification
• Millicandela Rating: Optical intensity may differ
• Viewing Angle: Angular distribution characteristics may vary
• Height (Max): Minor dimensional variations acceptable within through-hole compatibility
• Wavelength - Peak: Red spectrum variations (626nm to 635nm range)

Substitutes are classified into two categories: Parametric Equivalent (same manufacturer, different voltage) and Similar (different manufacturer, different voltage and optical characteristics).

Parameter Comparison

Engineering Selection Recommendations

4302H1-5V (Parametric Equivalent - VCC): This substitute is applicable when circuit design operates at 5V supply voltage. Mechanical compatibility is identical to the main part (same height, lens configuration, and through-hole radial package). Optical characteristics remain equivalent (8mcd, 60° viewing angle, 635nm peak wavelength, diffused lens). Both parts share identical RoHS3 compliance and REACH unaffected status. Test current reduces from 13mA to 10mA due to lower voltage specification. Selection is appropriate for direct substitution in 5V circuit applications without mechanical or compliance concerns.

HLMP-EG3E-QT000 (Similar - Broadcom Limited): This substitute is applicable when circuit design operates at 2.1V supply voltage. Mechanical compatibility is maintained through identical lens size (5mm T-1 3/4), lens style (round domed top), mounting type (through hole), and radial package configuration. Height differential (8.91mm vs. 10.08mm) remains within through-hole PCB tolerance ranges. Optical characteristics differ: viewing angle narrows to 30° (vs. 60°), peak wavelength shifts to 634nm (vs. 635nm), and millicandela rating is not specified. Test current increases to 20mA. RoHS3 compliance and REACH unaffected status are maintained. Selection requires circuit design accommodation for reduced viewing angle and lower voltage operation.

All three parts maintain active product status and regulatory compliance (ROHS3, REACH, EAR99 ECCN classification, HTSUS 8541.41.0000).

Frequently Asked Questions (FAQ)

Q: Can the 4302H1-12V be directly replaced with the 4302H1-5V?

A: Direct mechanical replacement is possible. Both parts share identical lens size (5mm T-1 3/4), lens style (round domed top), mounting type (through hole), package configuration (radial), and height (10.08mm). Optical characteristics are equivalent (8mcd, 60° viewing angle, 635nm peak wavelength, diffused lens). Substitution requires circuit voltage adjustment from 12V to 5V supply. Test current reduces from 13mA to 10mA.

Q: What are the key differences between the 4302H1-12V and HLMP-EG3E-QT000?

A: Both parts maintain mechanical compatibility in lens size (5mm T-1 3/4), lens style (round domed top), mounting type (through hole), and radial package. Key differences include: voltage operation (12V vs. 2.1V), viewing angle (60° vs. 30°), peak wavelength (635nm vs. 634nm), test current (13mA vs. 20mA), and height (10.08mm vs. 8.91mm). The HLMP-EG3E-QT000 does not specify millicandela rating or lens transparency. Substitution requires circuit redesign for 2.1V operation and accommodation of narrower viewing angle.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 4302H1-12V, 4302H1-5V, and HLMP-EG3E-QT000 are all ROHS3 compliant with REACH unaffected status and MSL 1 (unlimited moisture sensitivity level).

Q: What is the primary substitution criterion for these red LED components?

A: The primary criterion is mechanical and optical compatibility within the T-1 3/4 (5mm) through-hole radial package category. All substitutes maintain identical lens size, lens style (round domed top), mounting type (through hole), and radial configuration. Voltage, current, and viewing angle specifications vary based on circuit requirements.

Q: Can the HLMP-EG3E-QT000 be used in applications requiring 60° viewing angle?

A: No. The HLMP-EG3E-QT000 specifies 30° viewing angle, which is narrower than the 4302H1-12V (60°). Applications requiring 60° viewing angle distribution should use the 4302H1-12V or 4302H1-5V.

Q: What inventory levels are available for each part?

A: 4302H1-12V: 1927 pcs new original in stock; 4302H1-5V: 2640 pcs new original in stock; HLMP-EG3E-QT000: 1245 pcs new original in stock.
