TLVY4201 Equivalent & Substitute Parts

Part Overview

The TLVY4201 is a yellow 3mm through-hole LED manufactured by Vishay Semiconductor Opto Division, designed for indication applications with a dominant wavelength of 588nm. This part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing production support, design updates, and inventory management. The TLVY4200 serves as the direct parametric equivalent with identical electrical and mechanical specifications but maintains active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLVY4201 is determined by strict equivalence across the following critical parameters:

• Color and Wavelength: Yellow indication at 588nm dominant wavelength
• Electrical Performance: 2.4V forward voltage and 15mA test current
• Optical Output: 30mcd brightness rating
• Physical Form Factor: 3mm diameter lens with round domed top, 4.90mm maximum height
• Mounting Configuration: Through-hole radial package
• Regulatory Compliance: ROHS3 compliance and MSL Level 1

The TLVY4200 maintains complete parametric equivalence across all specified dimensions. Additional substitute candidates (5219431F, HLMP-1420, HLMP-1421) are listed in the TLVY4200 substitute chain and require independent verification against these core parameters.

Parameter Comparison

Engineering Selection Recommendations

The TLVY4200 is the direct replacement for the obsolete TLVY4201. Both components are manufactured by Vishay Semiconductor Opto Division within the TLV.420 series and maintain identical electrical, optical, and mechanical specifications. The TLVY4200 carries active product status with significantly higher inventory availability (4099 pcs vs. 667 pcs), ensuring supply chain continuity. Both parts meet ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for current production environments.

For applications currently using TLVY4201, transition to TLVY4200 requires no circuit redesign or performance validation, as all critical parameters remain unchanged. The packaging difference (TLVY4201 standard vs. TLVY4200 bulk) does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can TLVY4200 directly replace TLVY4201 without circuit modifications?

A: Yes. The TLVY4200 maintains identical forward voltage (2.4V), test current (15mA), brightness (30mcd), wavelength (588nm), and physical dimensions (3.40mm lens, 4.90mm height). No circuit changes are required.

Q: What is the primary reason for substitution?

A: TLVY4201 is classified as obsolete. TLVY4200 is the active equivalent from the same manufacturer and series, ensuring long-term supply availability and production support.

Q: Are there packaging differences between TLVY4201 and TLVY4200?

A: TLVY4201 is supplied in standard packaging, while TLVY4200 is supplied in bulk packaging. This distinction affects order quantities and handling but does not impact component performance or compatibility.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both TLVY4201 and TLVY4200 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What inventory status should influence purchasing decisions?

A: TLVY4200 maintains significantly higher inventory (4099 pcs) compared to TLVY4201 (667 pcs). For new designs and ongoing production, TLVY4200 is the recommended selection to ensure supply continuity.
