TLHG6200 Equivalent & Substitute Parts

Part Overview

The TLHG6200 is a green LED indicator manufactured by Vishay Semiconductor Opto Division, designed for through-hole mounting applications. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance requirements. The TLHG6200 features a 5mm T-1 3/4 form factor with clear lens transparency, 40mcd brightness rating, and 2.4V forward voltage specification. Identifying compatible alternatives ensures design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution compatibility for the TLHG6200 is determined by the following critical parameters:

Primary Compatibility Criteria:

Color: Green (all substitutes must be green)
Lens Size: 5mm, T-1 3/4 (physical form factor)
Mounting Type: Through Hole (circuit board integration method)
Package / Case: Radial (lead configuration)
Wavelength - Dominant: 569nm (optical output specification)
Wavelength - Peak: 565nm (spectral characteristics)

Secondary Compatibility Factors:

Voltage - Forward (Vf): 2.4V nominal (circuit design parameter)
Current - Test: 10mA (operational current specification)
Lens Transparency: Clear (optical clarity requirement)
RoHS Status: ROHS3 Compliant (regulatory compliance)

Substitute parts are grouped based on matching these parameters. Variations in millicandela rating and viewing angle are acceptable within the same functional category, provided the primary criteria remain aligned. Parts with differing forward voltage, wavelength specifications, or lens transparency are classified as alternative options rather than direct substitutes.

Engineering Selection Recommendations

Direct Substitutes (Active Product Status):

HLMP-3568 (Broadcom Limited) is the closest functional equivalent. It maintains green color, clear lens transparency, 5mm T-1 3/4 form factor, 569nm dominant wavelength, and through-hole radial mounting. Forward voltage is 2.1V (0.3V lower than TLHG6200), and brightness is reduced to 10.6mcd. This part is currently in active production status with ROHS3 compliance.

HLMP-C523 and HLMP-C523-J0002 (Broadcom Limited) offer higher brightness at 170mcd with 2.2V forward voltage and 25° viewing angle. These parts maintain wavelength compatibility (570nm dominant) and are in active production. The J0002 variant is available in Cut Tape packaging with significantly higher inventory (28,363 pcs).

LTL-307GE-012 (Lite-On Inc.) provides 60mcd brightness with 2.1V forward voltage and 40° viewing angle. Wavelength specifications match the TLHG6200 (569nm dominant, 565nm peak). This part is in active production status.

Alternative Options (Different Lens Transparency):

TLHG6400 (Vishay Semiconductor Opto Division) shares the same manufacturer and forward voltage (2.4V) but features diffused lens transparency instead of clear. Brightness is reduced to 10mcd with 60° viewing angle. Product status is obsolete.

Not Recommended for New Designs:

4300H5LC (Visual Communications Company - VCC) has product status classified as "Not For New Designs." Forward voltage is 1.8V with significantly reduced current specification (2mA test current). This part should not be selected for new applications.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3568 replace TLHG6200 directly in existing circuits?

A: HLMP-3568 is compatible with the same through-hole mounting and radial package configuration. However, forward voltage differs by 0.3V (2.1V vs. 2.4V), which may affect circuit current limiting calculations. Verify that your current-limiting resistor accommodates the lower voltage specification. Brightness is also reduced to 10.6mcd compared to 40mcd.

Q: What is the difference between HLMP-C523 and HLMP-C523-J0002?

A: Both parts are electrically identical with 170mcd brightness, 2.2V forward voltage, and 25° viewing angle. The primary difference is packaging: HLMP-C523 is supplied in Bulk packaging, while HLMP-C523-J0002 is supplied in Cut Tape (CT) format. The Cut Tape variant has significantly higher inventory availability (28,363 pcs vs. 5,850 pcs).

Q: Why is TLHG6400 listed as an alternative rather than a direct substitute?

A: TLHG6400 has diffused lens transparency, whereas TLHG6200 has clear lens transparency. This optical difference affects light distribution characteristics. TLHG6400 provides 60° viewing angle compared to TLHG6200's 28° angle, making it suitable for applications requiring wider light distribution but not for applications requiring focused, directional illumination.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance certification. This ensures compatibility with regulatory requirements for electronic components in the target markets.

Q: What should I consider when selecting between active and obsolete substitute parts?

A: Active product status indicates ongoing manufacturing and supply availability. HLMP-3568, HLMP-C515, HLMP-C523, HLMP-C523-J0002, HLMP-C615-G0001, and LTL-307GE-012 are all in active production. Obsolete parts (TLHG6200, TLHG6400) have limited remaining inventory and should only be used when existing stock is available. For new designs, select from active product options.

Q: How do wavelength specifications affect substitution?

A: The TLHG6200 has 569nm dominant wavelength and 565nm peak wavelength. Most substitute parts maintain these specifications. HLMP-C523 and HLMP-C615-G0001 have slightly different wavelengths (570nm and 559nm dominant, respectively). These variations are within the green LED spectrum but may produce slightly different perceived color. Verify that your application tolerates these minor wavelength shifts.

Q: Can I use HLMP-C515 as a substitute if my circuit requires higher brightness?

A: HLMP-C515 provides 300mcd brightness, significantly higher than TLHG6200's 40mcd. However, it requires 20mA test current (vs. 10mA for TLHG6200) and has a narrower 15° viewing angle. Your circuit design must accommodate the increased current draw and modified optical characteristics. Forward voltage is 2.2V, requiring resistor recalculation.
