EAPLTAA4 Equivalent & Substitute Parts

Part Overview

The EAPLTAA4 is a Fiber Optic Transmitter with Driver manufactured by Everlight Electronics Co Ltd, operating at 660nm wavelength with a data rate of 16Mbps across a supply voltage range of 2.7V to 5.5V. This component is designed for Digital Audio applications and is classified as Obsolete product status.

Due to the obsolete status of the EAPLTAA4, identifying equivalent substitute parts is essential for ongoing system maintenance, design updates, and procurement continuity. Substitute parts must maintain functional compatibility while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the EAPLTAA4 is determined by the following critical parameters:

Wavelength Matching: 660nm operation is mandatory for optical compatibility with existing receiver systems.

Supply Current: 10 mA supply current requirement must be maintained to ensure proper circuit integration without redesign of power delivery networks.

Supply Voltage Range: The substitute must operate within or encompass the 2.7V to 5.5V range to ensure compatibility with existing power supplies.

Application Compatibility: Digital Audio application designation indicates the component's intended use case.

Manufacturer Consistency: Parts from Everlight Electronics Co Ltd within the Photolink series maintain design and quality consistency.

The PLT237/T10WH meets these substitution criteria through matching wavelength (660nm), identical supply current (10 mA), overlapping voltage range (2.7V ~ 5V), and identical application classification (Digital Audio).

Parameter Comparison

Engineering Selection Recommendations

The PLT237/T10WH is a direct substitute for the EAPLTAA4 based on the following engineering criteria:

Optical Compatibility: Both components operate at 660nm wavelength, ensuring compatibility with existing receiver optics and signal detection systems.

Electrical Compatibility: Matching 10 mA supply current and overlapping voltage ranges (2.7V ~ 5V for PLT237/T10WH encompasses the critical operating window of the EAPLTAA4) permit direct circuit integration without power supply modifications.

Performance Enhancement: The PLT237/T10WH provides 25Mbps data rate capability, exceeding the 16Mbps specification of the EAPLTAA4. This enhanced performance does not create incompatibility and provides operational margin.

Compliance Status: Both components maintain ROHS3 compliance, satisfying regulatory requirements for equivalent substitution.

Product Availability: The PLT237/T10WH holds Active product status with 7877 units in stock, compared to the Obsolete EAPLTAA4 with 1117 units remaining. This availability differential supports long-term supply chain continuity.

Packaging Consideration: The PLT237/T10WH is supplied in Tube packaging, which may differ from the original EAPLTAA4 packaging specification. Verify packaging compatibility with existing assembly and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can the PLT237/T10WH directly replace the EAPLTAA4 in existing designs?

A: Yes. The PLT237/T10WH meets all critical substitution parameters: identical 660nm wavelength, matching 10 mA supply current, overlapping 2.7V ~ 5V supply voltage range, and identical Digital Audio application classification. The higher 25Mbps data rate does not create incompatibility.

Q: What is the voltage range difference between these parts?

A: The EAPLTAA4 operates at 2.7V ~ 5.5V, while the PLT237/T10WH operates at 2.7V ~ 5V. The PLT237/T10WH range is narrower at the upper limit by 0.5V. Verify that your system operates within the 2.7V ~ 5V window to ensure compatibility.

Q: Why does the PLT237/T10WH have a higher data rate?

A: The PLT237/T10WH is specified at 25Mbps compared to the EAPLTAA4 at 16Mbps. This represents an enhanced component variant within the Photolink series. The higher data rate capability does not affect substitution compatibility for 16Mbps applications.

Q: What is the packaging difference?

A: The PLT237/T10WH is supplied in Tube packaging. Confirm that your assembly process and handling procedures accommodate Tube packaging format before procurement.

Q: Are both components RoHS compliant?

A: Yes. Both the EAPLTAA4 and PLT237/T10WH are ROHS3 compliant, meeting environmental and regulatory requirements for equivalent substitution.

Q: What is the moisture sensitivity difference?

A: The EAPLTAA4 has MSL 1 (Unlimited), while the PLT237/T10WH has MSL 5A (24 Hours). This indicates the PLT237/T10WH requires more controlled moisture exposure during storage and handling. Implement appropriate moisture control procedures per IPC standards for MSL 5A components.
