TLVH4200 Equivalent & Substitute Parts

Part Overview

The TLVH4200 is a red LED indicator from Vishay Semiconductor Opto Division, designed for through-hole mounting in 3mm T-1 form factor applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance requirements. The TLVH4200 delivers 55mcd brightness at 2.4V forward voltage with a 170° viewing angle, suitable for general indication applications requiring high luminous intensity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TLVH4200 is determined by the following critical parameters:

• Color and Wavelength: Red LED with dominant wavelength 619nm and peak wavelength 635nm
• Lens Configuration: 3mm T-1 form factor with round domed top and clear lens
• Mounting Type: Through-hole radial configuration
• Electrical Characteristics: Forward voltage (Vf) and test current determine circuit compatibility
• Optical Performance: Millicandela rating and viewing angle define brightness and visibility requirements
• Compliance: RoHS3 compliance and MSL rating ensure regulatory and environmental compatibility

The substitute parts listed maintain compatibility across these core parameters while accommodating variations in specific electrical and optical characteristics within acceptable engineering tolerances for LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring regulatory alignment with the original TLVH4200. The substitute parts are classified as active products, providing long-term availability and supply chain stability compared to the obsolete status of the original part.

5219432F (Dialight): This part maintains the 3mm form factor with radial through-hole mounting. The 29mcd brightness rating is lower than the TLVH4200, suitable for applications where reduced luminous intensity is acceptable. The 20mA test current and unspecified forward voltage require circuit validation.

HLMP-1321 and HLMP-1321-G0002 (Broadcom Limited): Both variants share identical electrical and optical specifications. The HLMP-1321-G0002 is supplied in cut tape packaging, while the standard HLMP-1321 is supplied in bulk. These parts operate at 1.9V forward voltage and 10mA test current, resulting in lower power consumption than the TLVH4200. The 30mcd brightness and 45° viewing angle differ from the original specification and require circuit compatibility assessment. The increased height (6.35mm vs. 4.90mm) must be verified against mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the 5219432F directly replace the TLVH4200 in all applications?

A: The 5219432F maintains the 3mm T-1 form factor and through-hole radial mounting, but the 29mcd brightness is approximately 47% lower than the TLVH4200's 55mcd rating. Applications requiring the original brightness specification must account for this reduction. Forward voltage is not specified for the 5219432F, requiring circuit validation before substitution.

Q: What are the key differences between HLMP-1321 and HLMP-1321-G0002?

A: Both parts are electrically and optically identical. The primary difference is packaging: HLMP-1321 is supplied in bulk, while HLMP-1321-G0002 is supplied in cut tape. Selection depends on assembly process requirements and volume considerations.

Q: Are the HLMP-1321 variants suitable for high-brightness applications?

A: The HLMP-1321 variants deliver 30mcd brightness, which is 45% lower than the TLVH4200. These parts are suitable for standard indication applications but not for applications requiring the original 55mcd specification. The 45° viewing angle is also narrower than the TLVH4200's 170° angle.

Q: What circuit modifications are required when substituting with lower forward voltage parts?

A: The HLMP-1321 variants operate at 1.9V compared to the TLVH4200's 2.4V. This 0.5V difference affects current-limiting resistor calculations. Existing series resistor values must be recalculated based on the new forward voltage to maintain proper LED current and brightness.

Q: Do all substitute parts meet the same compliance standards as the TLVH4200?

A: Yes. All substitute parts are ROHS3 compliant with MSL Level 1 rating, matching the original TLVH4200 specifications. All parts are classified as REACH Unaffected with EAR99 ECCN designation.

Q: What is the impact of increased LED height on PCB layout?

A: The HLMP-1321 variants have a maximum height of 6.35mm compared to the TLVH4200's 4.90mm. This 1.45mm increase must be verified against mechanical clearance requirements, including enclosure height, component spacing, and assembly constraints.
