Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following parameters:

• Color: Green
• Mounting Type: Through Hole
• Lens Transparency: Diffused
• Lens Size: 3mm or T-1 (3mm equivalent)
• Voltage - Forward (Vf): 2.1V to 2.4V range
• Current - Test: 10mA to 20mA range
• Viewing Angle: 55° to 170°
• Package / Case: Radial

The substitute parts are grouped into two categories:

Direct Equivalent (Base Product Relationship): Part 5219210F is a direct variant of the main part number, maintaining identical electrical characteristics and diffused lens configuration with improved RoHS3 compliance and active product status.

Functional Equivalents (Similar Specifications): Parts 4303F5, HLMP-K600, SSL-LX3044GD, and TLVG4200 are functionally equivalent green through-hole LEDs with diffused or clear lenses, operating within compatible voltage and current ranges. These parts maintain the same mounting type and general form factor while offering variations in brightness, viewing angle, and wavelength characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Dialight 5219210F

The 5219210F is the preferred substitute, offering direct electrical equivalence to the main part (2.1V, 12.6mcd, 60° viewing angle) while providing active product status and ROHS3 compliance. This part maintains identical lens configuration and brightness characteristics, requiring no circuit redesign. The reduced test current (10mA vs. 20mA) provides improved power efficiency.

Secondary Recommendations:

• SSL-LX3044GD (Lumex): Suitable for applications requiring higher brightness (40mcd) with maintained 60° viewing angle and 2.2V forward voltage. Height reduction to 4.60mm accommodates space-constrained designs. ROHS3 compliant with active status.

• 4303F5 (VCC): Appropriate for designs tolerating increased brightness (25mcd) and slightly reduced viewing angle (55°). Maintains 2.1V forward voltage and diffused lens. ROHS3 compliant with active status.

• HLMP-K600 (Broadcom): Suitable only for applications where reduced brightness (1mcd) is acceptable. Maintains 2.1V forward voltage and 60° viewing angle. ROHS3 compliant with active status.

• TLVG4200 (Vishay): Applicable for designs requiring wide viewing angle (170°) and higher brightness (30mcd). Forward voltage increases to 2.4V, requiring circuit verification. Clear lens differs from diffused configuration. ROHS3 compliant with active status.

All substitute parts maintain through-hole radial mounting compatibility and unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can 5219210F be used as a direct replacement for 5219210?

A: Yes. The 5219210F maintains identical electrical specifications (2.1V, 12.6mcd, 60° viewing angle) and diffused lens configuration. The reduced test current (10mA vs. 20mA) is a design improvement. No circuit modifications are required.

Q: What is the primary difference between diffused and clear lens options?

A: Diffused lenses scatter light over a wider area with reduced peak intensity, suitable for general indication. Clear lenses concentrate light in a narrower beam with higher peak intensity. The TLVG4200 (clear lens) provides 170° viewing angle compared to 60° for diffused options, but with different light distribution characteristics.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (5219210F, 4303F5, HLMP-K600, SSL-LX3044GD, TLVG4200) are ROHS3 compliant, whereas the original 5219210 is RoHS non-compliant.

Q: Which substitute offers the closest brightness match to the original 5219210?

A: The 5219210F provides exact brightness equivalence at 12.6mcd. The SSL-LX3044GD (40mcd) and TLVG4200 (30mcd) offer higher brightness, while HLMP-K600 (1mcd) offers significantly lower brightness.

Q: Do substitute parts fit the same PCB footprint?

A: All substitute parts maintain through-hole radial mounting with compatible lead spacing. Height variations (4.60mm to 6.40mm) may affect clearance in space-constrained applications. Verify mechanical fit for designs with height restrictions.

Q: What forward voltage range is acceptable for substitution?

A: The original 5219210 operates at 2.1V. Substitute parts operate between 2.1V and 2.4V. The TLVG4200 at 2.4V requires circuit verification to ensure current-limiting resistor values remain appropriate. Other substitutes at 2.1V to 2.2V require no circuit adjustment.

Q: Can TLVG4200 be used in applications designed for 60° viewing angle?

A: No. The TLVG4200 provides 170° wide-angle viewing, fundamentally different from the 60° specification of the original part. Use only in applications where wide-angle distribution is acceptable or required.
