TLVP4201 Equivalent & Substitute Parts

Part Overview

The TLVP4201 is a green 560nm LED indicator from Vishay Semiconductor Opto Division, designed for discrete 2.4V radial through-hole applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The TLVP4201 features a 3mm T-1 round domed lens with 30mcd brightness and 170° viewing angle, suitable for standard indication applications requiring clear green illumination.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TLVP4201 is determined by the following critical parameters:

• Color and Wavelength: All substitutes must be green LEDs with dominant wavelength in the 560-569nm range and peak wavelength at 555-565nm
• Voltage Rating: Forward voltage must be compatible with 2.4V nominal operation; 2.1V alternatives are acceptable with circuit adjustment
• Lens Configuration: 3mm T-1 form factor with clear transparency required for mechanical and optical compatibility
• Mounting Type: Through-hole radial package mandatory for PCB compatibility
• Viewing Angle: 45° to 170° acceptable depending on application requirements
• Brightness: 22-30mcd range acceptable for indication applications

Substitutes are grouped into two categories:

Category 1 - Direct Parametric Equivalents: TLVP4202 and TLVG4200 maintain identical forward voltage (2.4V), wavelength specifications, and mechanical form factor. These provide the closest functional replacement.

Category 2 - Functional Equivalents: HLMP-1520, HLMP-1521, and HLMP-1521-E0002 operate at lower forward voltage (2.1V) with reduced brightness (22mcd) and narrower viewing angle (45°). These require circuit verification but are electrically compatible.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred)

TLVP4202 and TLVG4200 are the primary substitutes for TLVP4201. Both maintain 2.4V forward voltage and are classified as active products with ROHS3 compliance. TLVG4200 provides the closest parametric match with identical 30mcd brightness and 170° viewing angle. TLVP4202 operates at higher test current (20mA) and features a flat-top lens instead of domed, requiring mechanical fit verification in constrained applications.

For Functional Replacement (With Circuit Verification)

HLMP-1520, HLMP-1521, and HLMP-1521-E0002 from Broadcom are functionally compatible but operate at reduced forward voltage (2.1V) and brightness (22mcd) with narrower viewing angle (45°). These parts are suitable only when circuit design accommodates lower voltage operation and reduced light output. HLMP-1521-E0002 is packaged in Tape & Reel format for automated assembly; HLMP-1520 and HLMP-1521 are available in bulk packaging. All three are active products with ROHS3 compliance.

Packaging Considerations

TLVG4200 is supplied in bulk packaging. HLMP-1521-E0002 is supplied in Tape & Reel format for high-volume production. Standard bulk packaging is available for HLMP-1520 and HLMP-1521. Packaging selection depends on assembly process requirements and volume.

Frequently Asked Questions (FAQ)

Q: Can TLVP4202 be used as a direct replacement for TLVP4201?

A: TLVP4202 is electrically compatible with identical 2.4V forward voltage and 560nm wavelength. The primary difference is lens style (flat top vs. domed) and slightly larger diameter (3.40mm). Mechanical fit in the PCB assembly must be verified before substitution.

Q: What is the key difference between Vishay and Broadcom substitutes?

A: Vishay substitutes (TLVP4202, TLVG4200) maintain 2.4V forward voltage and 30mcd brightness. Broadcom substitutes (HLMP-1520, HLMP-1521, HLMP-1521-E0002) operate at 2.1V with 22mcd brightness and 45° viewing angle. Broadcom parts require circuit adjustment for voltage and brightness differences.

Q: Is TLVG4200 suitable for direct replacement?

A: Yes. TLVG4200 provides parametric equivalence with 2.4V forward voltage, 30mcd brightness, 170° viewing angle, and identical 3mm T-1 form factor. The dominant wavelength is 569nm versus 560nm for TLVP4201, which is within acceptable green LED specification range.

Q: Can HLMP-1521-E0002 be used in manual assembly?

A: HLMP-1521-E0002 is supplied in Tape & Reel packaging optimized for automated pick-and-place assembly. Manual assembly is possible but not the intended application. HLMP-1521 in bulk packaging is more suitable for manual assembly processes.

Q: What are the height constraints for substitution?

A: TLVP4201, TLVP4202, and TLVG4200 have maximum height of 4.90mm. HLMP-1520, HLMP-1521, and HLMP-1521-E0002 have maximum height of 6.35mm. Applications with height restrictions below 5.0mm must use Vishay parts only.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitutes are ROHS3 compliant and REACH unaffected, matching the compliance status of TLVP4201.
