EALP05RDFRGA2 Equivalent & Substitute Parts

Part Overview

The EALP05RDFRGA2 is a dual-color LED indicator manufactured by Everlight Electronics Co Ltd, featuring integrated Red (624nm) and Yellow-Green (573nm) emitters in a common cathode configuration. This through-hole component is designed for LED indication applications requiring simultaneous red and yellow-green color capability in a compact 5mm T-1 3/4 form factor.

The EALP05RDFRGA2 is classified as Obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EALP05RDFRGA2 is determined by strict alignment with the following critical parameters:

Physical & Mechanical Compatibility:

• Lens size must be 5mm, T-1 3/4 form factor
• Mounting type must be through-hole
• Package configuration must be radial with 3 leads
• Lens style must be round with domed top
• Lens transparency must be diffused

Electrical Compatibility:

• Configuration must be common cathode
• Forward voltage (Vf) must be within the operating range of the original design (2V nominal for each color)
• Test current must be 20mA per color
• Color combination must support red and green/yellow-green wavelengths

Regulatory & Environmental:

• RoHS compliance status must be maintained
• ECCN and HTSUS classifications must align

The SSL-LX5099IGW manufactured by Lumex Opto/Components Inc. meets these substitution criteria with the following considerations: the color order is reversed (Green/Red versus Red/Yellow-Green), the viewing angle is narrower (60° versus 70°), and the maximum height is reduced (11.00mm versus 13.30mm). These differences do not preclude substitution in applications where the physical envelope and optical characteristics are compatible with the design requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The EALP05RDFRGA2 is classified as Obsolete, making the SSL-LX5099IGW an active substitute with ongoing manufacturer support and availability. The SSL-LX5099IGW is currently in active production status, ensuring long-term supply chain reliability and technical support.

Regulatory Compliance

Both components meet export control requirements (ECCN: EAR99) and tariff classifications (HTSUS: 8541.41.0000). The SSL-LX5099IGW provides enhanced RoHS3 compliance and superior moisture sensitivity rating (MSL 1 with unlimited shelf life versus MSL 2 with 1-year limitation), reducing storage and handling constraints.

Physical & Electrical Compatibility

The SSL-LX5099IGW maintains identical lens size (5mm T-1 3/4), mounting type (through-hole), package configuration (radial 3-lead), and lens characteristics (diffused, round domed top). Forward voltage specifications are compatible: 2V for red emitters and 2V/2.2V for green/yellow-green emitters within standard design tolerances. Test current remains 20mA for both colors.

Design Integration Factors

The SSL-LX5099IGW exhibits a narrower viewing angle (60° versus 70°) and reduced maximum height (11.00mm versus 13.30mm). These differences require verification against specific application requirements regarding optical field of view and PCB clearance constraints. The color sequence reversal (Green/Red versus Red/Yellow-Green) necessitates circuit-level lead reassignment but does not affect functional capability in common cathode configurations.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX5099IGW directly replace the EALP05RDFRGA2 without circuit modification?

A: Physical and electrical compatibility is established for through-hole mounting and common cathode operation. However, the color sequence is reversed (Green/Red versus Red/Yellow-Green), requiring lead reassignment in the circuit. Verify that the narrower viewing angle (60° versus 70°) and reduced height (11.00mm versus 13.30mm) are compatible with your optical and mechanical design requirements.

Q: What are the key differences in electrical specifications?

A: Forward voltage for the green emitter in the SSL-LX5099IGW is 2.2V compared to 2V for the yellow-green emitter in the EALP05RDFRGA2. Both components operate at 20mA test current. This 0.2V difference for the green emitter falls within standard design tolerance ranges for LED indicator circuits but should be verified in current-limiting resistor calculations.

Q: Why is the SSL-LX5099IGW considered a valid substitute despite the viewing angle difference?

A: The SSL-LX5099IGW viewing angle of 60° is narrower than the EALP05RDFRGA2 at 70°. Substitution validity depends on application-specific requirements for optical field of view. Applications requiring wide-angle indication may require design review; applications with directional viewing requirements may benefit from the narrower angle.

Q: What is the significance of the MSL rating difference?

A: The EALP05RDFRGA2 has MSL 2 (1-year shelf life), while the SSL-LX5099IGW has MSL 1 (unlimited shelf life). This indicates superior moisture resistance in the substitute part, reducing storage constraints and improving long-term inventory management for manufacturing environments.

Q: Are both components RoHS compliant?

A: Yes. The EALP05RDFRGA2 is RoHS Compliant, and the SSL-LX5099IGW is ROHS3 Compliant. Both meet environmental and hazardous substance restrictions. The ROHS3 designation on the substitute indicates compliance with the most current RoHS directive requirements.

Q: What packaging considerations apply to the SSL-LX5099IGW?

A: The SSL-LX5099IGW is supplied in Bulk packaging, compared to the EALP05RDFRGA2 standard packaging. Verify that bulk packaging meets your procurement, handling, and inventory management requirements. Both components use identical radial 3-lead through-hole package configuration.
