TLHG6205 Equivalent & Substitute Parts

Part Overview

The TLHG6205 is a green LED indicator manufactured by Vishay Semiconductor Opto Division, designed for through-hole mounting applications. This part features a 5mm T-1 3/4 form factor with a clear lens and 40mcd brightness rating at 2.4V forward voltage. The TLHG6205 is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility with the through-hole radial mounting configuration and deliver comparable optical and electrical performance within acceptable parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the TLHG6205 are selected based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

Color: Green (all substitutes must be green)
Lens Transparency: Clear (optical clarity requirement)
Lens Size: 5mm, T-1 3/4 (physical form factor)
Mounting Type: Through Hole, Radial (PCB integration method)
Wavelength - Dominant: 569nm ±10nm range (optical specification)
Voltage - Forward (Vf): 2.1V to 2.4V (circuit design tolerance)
Current - Test: 10mA to 20mA (standard LED operating range)
RoHS Status: ROHS3 Compliant (regulatory requirement)

Substitutes are grouped into two categories:

Category A - Direct Substitutes (Active Status): Parts with matching wavelength (569nm), clear lens, and forward voltage within 2.1V to 2.2V range. These include HLMP-3568, HLMP-C515, HLMP-C515-L0002, LTL-307GE-012, and LTL-4234-012. These parts maintain the optical and electrical characteristics of the original TLHG6205.

Category B - Functional Alternatives (Active Status): Parts with compatible wavelength range (559nm to 570nm), clear lens, and forward voltage 2.2V. These include HLMP-C523, HLMP-C523-J0002, and HLMP-C615-G0001. These parts provide equivalent functionality with minor variations in brightness and viewing angle.

Category C - Limited Compatibility: The 4300H5LC (diffused lens, 1.8V, 2.3mcd) is included as a substitute reference but has significant parameter differences and should be evaluated for specific application requirements.

Engineering Selection Recommendations

For Active Production Applications:

Select from Broadcom HLMP series or Lite-On LTL series parts, all classified as Active status. These manufacturers provide long-term availability and supply chain stability. HLMP-C515 and HLMP-C515-L0002 deliver the highest brightness (300mcd) with 569nm wavelength matching, suitable for applications requiring enhanced visibility. HLMP-C523 and HLMP-C523-J0002 provide moderate brightness (170mcd) with slightly longer wavelength (570nm), acceptable for standard indication applications. LTL-307GE-012 and LTL-4234-012 offer 60mcd brightness with 569nm wavelength and lower forward voltage (2.1V), reducing power consumption in battery-powered designs.

For Maintenance and Legacy System Support:

HLMP-3568 maintains the lowest test current (10mA) matching the original TLHG6205 specification, minimizing circuit redesign. This part is suitable for direct replacement in existing designs with minimal modification.

Compliance and Regulatory Considerations:

All recommended substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Packaging options include Bulk, Cut Tape (CT), and Tape & Reel (TR) formats to accommodate different procurement and assembly workflows.

Avoid:

The 4300H5LC is classified as Not For New Designs and features diffused lens transparency, significantly lower brightness (2.3mcd), and reduced forward voltage (1.8V), making it unsuitable for direct replacement of the TLHG6205 in new applications.

Frequently Asked Questions (FAQ)

Q: Can HLMP-C515 directly replace TLHG6205 in existing circuit designs?

A: HLMP-C515 is electrically compatible with forward voltage of 2.2V versus TLHG6205's 2.4V. However, HLMP-C515 operates at 20mA test current compared to TLHG6205's 10mA. Circuit current-limiting resistor values must be recalculated to accommodate the lower forward voltage and higher test current. The 300mcd brightness is significantly higher than the original 40mcd, which may require optical diffusion or reduced drive current depending on application requirements.

Q: What is the difference between HLMP-C515 and HLMP-C515-L0002?

A: Both parts are electrically and optically identical with matching 300mcd brightness, 2.2V forward voltage, and 569nm wavelength. The primary difference is packaging: HLMP-C515 is supplied in Bulk format, while HLMP-C515-L0002 is supplied in Cut Tape (CT) format. Selection depends on assembly process requirements and inventory management preferences.

Q: Are Lite-On LTL-307GE-012 and LTL-4234-012 interchangeable?

A: Both parts share identical electrical specifications (2.1V forward voltage, 60mcd brightness, 569nm wavelength) and physical form factor. The primary difference is viewing angle: LTL-307GE-012 provides 40° viewing angle, while LTL-4234-012 provides 16° viewing angle. Selection depends on application-specific visibility requirements and circuit board layout constraints.

Q: Why is HLMP-C615-G0001 listed as a substitute if its wavelength is 559nm instead of 569nm?

A: HLMP-C615-G0001 is included as a functional alternative within the acceptable green LED wavelength range. The 559nm wavelength produces a slightly different shade of green compared to the 569nm standard, but remains within the green spectrum for indication applications. This part is suitable only for applications where wavelength variation is acceptable.

Q: Can 4300H5LC be used as a substitute for TLHG6205?

A: 4300H5LC is not recommended as a direct substitute. It features diffused lens transparency (versus clear), significantly lower brightness (2.3mcd versus 40mcd), reduced forward voltage (1.8V versus 2.4V), and is classified as Not For New Designs. This part is suitable only for legacy system maintenance where exact brightness and optical characteristics are not critical.

Q: What packaging format should be selected for high-volume production?

A: Tape & Reel (TR) format is recommended for automated assembly processes, available for LTL-307GE-012, LTL-4234-012, and HLMP-C615-G0001. Cut Tape (CT) format is suitable for moderate-volume production, available for HLMP-C515-L0002 and HLMP-C523-J0002. Bulk packaging is appropriate for manual assembly or low-volume applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
