Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WP57EGW is determined by the following criteria:

Primary Compatibility Parameters:

• Lens size and mounting type (5mm T-1 3/4 through-hole radial configuration)
• Color configuration (green and red dual-color capability)
• Lens transparency (diffused)
• Forward voltage compatibility within ±0.3V tolerance for each color
• Test current rating (20mA operation)
• RoHS3 compliance and regulatory status

Secondary Consideration Parameters:

• Brightness rating (millicandela values may vary)
• Viewing angle (30° to 60° range acceptable for general indication applications)
• Wavelength specifications (peak wavelength within ±10nm acceptable)
• Physical height (8.50mm to 8.60mm range for standard T-1 3/4 packages)

Configuration Constraints:

• Bidirectional configuration preferred; common cathode alternatives acceptable with circuit redesign
• Radial lead count: 2-lead bidirectional or 3-lead common cathode configurations both qualify

The following parts meet these substitution criteria: SSL-LX5097IGW, TLUV5300, 5BC, LTL-293SJW, SSL-LX5093IGW.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Bidirectional Configuration, Matched Vf):

SSL-LX5093IGW (Lumex Opto/Components Inc.) provides the closest electrical match to WP57EGW with identical forward voltages (2.2V green, 2.0V red), 20mA test current, and bidirectional configuration. Physical dimensions and RoHS3 compliance are equivalent. Brightness ratings differ (20mcd green, 30mcd red versus 30mcd green, 14mcd red), requiring circuit verification for brightness-critical applications. All regulatory certifications match.

SSL-LX5097IGW (Lumex Opto/Components Inc.) operates at 2.1V green and 2.1V red with common cathode configuration, requiring circuit redesign from bidirectional topology. Brightness ratings (20mcd green, 20mcd red) and 60° viewing angle differ from the original specification. RoHS3 compliance and active product status confirmed.

Acceptable Substitutes (Bidirectional Configuration, Vf Within Tolerance):

LTL-293SJW (Lite-On Inc.) operates at 2.1V green and 1.8V red, within acceptable tolerance ranges. Bidirectional configuration maintained. Brightness ratings significantly higher (40mcd green, 90mcd red) and 60° viewing angle require application assessment. RoHS3 compliant and active status confirmed.

5BC (Bivar Inc.) operates at 2.1V green and 2.0V red with bidirectional configuration. Brightness ratings substantially lower (8mcd green, 6mcd red) and 45° viewing angle represent significant deviations. RoHS3 compliant and active status confirmed. Suitable only for low-brightness indication applications.

Alternative Configuration (Common Cathode, Vf Variation):

TLUV5300 (Vishay Semiconductor Opto Division) operates at 2.4V green and 2.0V red with common cathode configuration and 10mA test current. Physical height (12.60mm) exceeds standard T-1 3/4 envelope. Brightness ratings substantially lower (2.5mcd green, 2.5mcd red). RoHS3 compliant and active status confirmed. Requires significant circuit redesign and is suitable only for space-constrained, low-brightness applications.

Selection Criteria Summary:

All substitute parts maintain ROHS3 compliance and active product status. Forward voltage compatibility within ±0.3V is achievable with SSL-LX5093IGW, SSL-LX5097IGW, LTL-293SJW, and 5BC. Bidirectional configuration is preserved in all parts except SSL-LX5097IGW and TLUV5300. Brightness and viewing angle variations require application-specific evaluation based on circuit design and optical requirements.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX5097IGW replace WP57EGW directly without circuit modification?

A: No. SSL-LX5097IGW uses common cathode configuration with 3 leads, while WP57EGW is bidirectional with 2 leads. Circuit redesign is required to accommodate the different lead configuration and cathode connection topology.

Q: What is the maximum forward voltage difference acceptable between WP57EGW and substitute parts?

A: Forward voltage tolerance of ±0.3V per color is acceptable for general indication applications. SSL-LX5093IGW matches exactly (2.2V green, 2.0V red). LTL-293SJW operates at 2.1V green and 1.8V red, within tolerance. TLUV5300 at 2.4V green exceeds tolerance for green channel.

Q: Are all substitute parts available in the same through-hole radial package?

A: Yes. All substitute parts use 5mm T-1 3/4 through-hole radial mounting. Physical height varies slightly (8.50mm to 8.60mm for standard parts; TLUV5300 at 12.60mm exceeds standard envelope). PCB layout verification is required for TLUV5300.

Q: Which substitute offers the closest brightness match to WP57EGW?

A: SSL-LX5093IGW provides moderate brightness (20mcd green, 30mcd red) with identical forward voltages. LTL-293SJW offers higher brightness (40mcd green, 90mcd red) but with lower red forward voltage (1.8V). 5BC and TLUV5300 provide significantly lower brightness ratings unsuitable for standard indication applications.

Q: Can TLUV5300 be used in space-constrained applications?

A: No. TLUV5300 physical height (12.60mm) exceeds the standard T-1 3/4 envelope (8.60mm maximum). It is suitable only for applications with relaxed height constraints. Additionally, 10mA test current and 2.5mcd brightness ratings limit its use to low-intensity indication only.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (SSL-LX5093IGW, SSL-LX5097IGW, LTL-293SJW, 5BC, TLUV5300) are ROHS3 compliant with active product status, matching WP57EGW regulatory requirements.

Q: What is the primary difference between bidirectional and common cathode configurations?

A: Bidirectional LEDs (WP57EGW, SSL-LX5093IGW, LTL-293SJW, 5BC) use 2 leads with independent anode/cathode pairs for each color, allowing independent color control. Common cathode LEDs (SSL-LX5097IGW, TLUV5300) use 3 leads with a shared cathode, requiring different circuit topology and current-limiting resistor configuration.

Q: Which substitute part has the widest viewing angle?

A: LTL-293SJW, SSL-LX5097IGW, and TLUV5300 all offer 60° viewing angle, compared to WP57EGW and SSL-LX5093IGW at 30°. Wider viewing angles reduce brightness intensity per unit area and are suitable for applications requiring broader visibility.
