Key Parameters

Substitute Part Grouping Explanation

Substitution of the EAPLRAA4 is evaluated based on the following critical parameters that define functional compatibility:

Primary Substitution Criteria:

• Voltage supply range compatibility (minimum overlap required)
• Optical receiver functionality classification
• RoHS compliance status
• Moisture sensitivity level
• Series compatibility (Photolink family)
• Manufacturer consistency (Everlight Electronics Co Ltd)

The PLR237/T10BK qualifies as a substitute based on the following alignment:

• Both components are fiber optic receivers from the Photolink series manufactured by Everlight Electronics Co Ltd
• Both operate within overlapping voltage ranges (EAPLRAA4: 2.4V ~ 5.5V; PLR237/T10BK: 3V ~ 5.5V)
• Both are ROHS3 compliant
• Both feature MSL rating of 1 (Unlimited)
• Both are classified for optical applications

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The EAPLRAA4 is obsolete, while the PLR237/T10BK is active and currently in production. The PLR237/T10BK maintains active inventory status with 7512 pieces available, compared to 723 pieces of the EAPLRAA4.

Compliance Alignment: Both components meet ROHS3 compliance requirements and share identical MSL ratings, ensuring regulatory and environmental handling consistency.

Voltage Supply Range: The PLR237/T10BK operates within a 3V ~ 5.5V range, which overlaps with the EAPLRAA4's 2.4V ~ 5.5V specification. Systems operating at voltages below 3V require verification of PLR237/T10BK compatibility or alternative sourcing.

Manufacturer Consistency: Both components originate from Everlight Electronics Co Ltd within the Photolink series, ensuring design lineage and technical support continuity.

Frequently Asked Questions (FAQ)

Q: Can the PLR237/T10BK directly replace the EAPLRAA4 in all applications?

A: The PLR237/T10BK is functionally compatible as a fiber optic receiver from the same manufacturer and series. However, systems requiring operation below 3V supply voltage must be evaluated separately, as the PLR237/T10BK minimum supply voltage is 3V compared to the EAPLRAA4's 2.4V minimum.

Q: What is the significance of the EAPLRAA4 being obsolete?

A: Obsolete status indicates the component is no longer manufactured or supported by Everlight Electronics Co Ltd. The PLR237/T10BK, classified as active, represents the current production alternative within the Photolink series.

Q: Are there packaging differences between these components?

A: The PLR237/T10BK is specified with Tube packaging. The EAPLRAA4 packaging specification is not provided in the available data. Packaging compatibility should be verified against your assembly and handling requirements.

Q: Do both components meet the same environmental and compliance standards?

A: Yes. Both the EAPLRAA4 and PLR237/T10BK are ROHS3 compliant and feature MSL rating 1 (Unlimited), indicating identical moisture sensitivity handling requirements.

Q: What parameters are not specified for the PLR237/T10BK?

A: The PLR237/T10BK data does not include data rate, minimum receivable power, or supply current specifications. These parameters should be obtained from the manufacturer's detailed datasheet for complete performance verification.
