TLVG4200 Equivalent & Substitute Parts

Part Overview

The TLVG4200 is a green LED indicator manufactured by Vishay Semiconductor Opto Division, designed for through-hole applications in discrete indication circuits. This T-1 form factor component operates at 2.4V forward voltage with a 30mcd brightness rating and 569nm dominant wavelength. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide design flexibility for applications requiring equivalent green LED indication functionality with compatible electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLVG4200 are qualified based on the following criteria:

Electrical Compatibility: Forward voltage (Vf), test current, and wavelength characteristics must support operation in circuits designed for the primary part. The TLVG4200 operates at 2.4V with 15mA test current; substitute parts operate at 2.1V with 10mA test current, representing lower power consumption while maintaining green indication at 569nm dominant wavelength.

Mechanical Compatibility: Lens size (3mm, T-1), mounting type (through-hole radial), and package configuration must be identical to ensure direct board-level substitution without layout modifications.

Regulatory Compliance: All substitute parts must maintain RoHS3 compliance and REACH unaffected status to meet current environmental and regulatory requirements.

Optical Performance: Color (green), lens transparency (clear), and dominant wavelength (569nm) must match the primary part. Millicandela rating and viewing angle may vary within acceptable ranges for indication applications.

The identified substitutes (HLMP-1520 and HLMP-1521, both Broadcom Limited) meet all mechanical and regulatory criteria. Both operate at lower forward voltage and test current, which may require circuit verification for applications with strict current budgeting.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full RoHS3 compliance, qualifying them for current design applications. HLMP-1520 and HLMP-1521 are electrically interchangeable substitutes with identical specifications to each other, differing only in manufacturer inventory levels.

Circuit designers must account for the following differences when selecting substitutes:

Forward Voltage Difference: The TLVG4200 operates at 2.4V versus 2.1V for HLMP-1520/1521. This 0.3V reduction affects series resistor calculations and total circuit voltage drop. Circuits designed for the TLVG4200 may require resistor value adjustment to maintain proper current limiting for substitute parts.

Brightness Difference: The TLVG4200 provides 30mcd at 15mA test current, while substitutes provide 22mcd at 10mA. The lower brightness of substitute parts may impact visibility in high-ambient-light applications.

Viewing Angle Difference: The TLVG4200 offers 170° viewing angle versus 45° for substitutes. Applications requiring wide-angle indication must retain the TLVG4200.

Physical Height: Substitute parts measure 6.35mm maximum height versus 4.90mm for the TLVG4200. PCB clearance and enclosure constraints must be verified.

Frequently Asked Questions (FAQ)

Q: Can HLMP-1520 and HLMP-1521 be used interchangeably with TLVG4200?

A: Both Broadcom parts are mechanically and electrically compatible substitutes. However, circuit verification is required due to differences in forward voltage (2.1V vs. 2.4V), brightness (22mcd vs. 30mcd), and viewing angle (45° vs. 170°). Series resistor values must be recalculated for the lower forward voltage.

Q: What is the primary difference between HLMP-1520 and HLMP-1521?

A: Both parts are identical in electrical and mechanical specifications. The difference is inventory availability: HLMP-1520 has 19,077 units in stock while HLMP-1521 has 2,220 units in stock.

Q: Will the substitute parts fit in the same PCB footprint as TLVG4200?

A: Yes. All three parts use identical 3mm T-1 through-hole radial packages. However, the substitute parts are 1.45mm taller (6.35mm vs. 4.90mm), which may affect clearance in confined spaces or under low-profile enclosures.

Q: Are there viewing angle considerations when substituting?

A: Yes. The TLVG4200 provides 170° viewing angle, suitable for omnidirectional indication. Substitute parts provide only 45° viewing angle, limiting visibility to a narrower cone. Applications requiring wide-angle indication must use the TLVG4200.

Q: Do all parts meet current environmental regulations?

A: Yes. TLVG4200, HLMP-1520, and HLMP-1521 are all RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
