Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WP73EB/2SRDA are identified based on the following critical parameters that determine functional compatibility:

Configuration Match: Dual-level red LED (2 High Red x 2) configuration maintained across all substitutes.

Mounting Compatibility: Through-hole, right-angle mounting type preserved to ensure PCB assembly compatibility.

Optical Characteristics: Diffused, tinted lens type with round domed top maintained for consistent light distribution and appearance.

Electrical Operating Range: Substitute parts operate within compatible voltage and current specifications suitable for standard circuit board indicator applications.

Compliance Requirements: All substitute parts maintain RoHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory and environmental compatibility.

Viewing Angle: 60° viewing angle maintained across substitutes for consistent visibility characteristics.

The SSF-LXH250IID from Lumex Opto/Components Inc. qualifies as a substitute based on these parameters, with variations in lens diameter (5mm vs. 4.80mm), wavelength (635nm vs. 660nm), current rating (20mA vs. 30mA), and luminous intensity (40mcd vs. 300mcd) representing design trade-offs within the dual-level red LED indicator category.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The WP73EB/2SRDA remains the preferred selection when available, as it is the specified component with confirmed Active product status and established supply chain presence (709 Pcs in stock).

Substitute Selection Criteria: The SSF-LXH250IID qualifies as a functional substitute when the primary part is unavailable. Both components maintain Active product status and full regulatory compliance (RoHS3, REACH Unaffected, MSL 1).

Application Considerations: Selection between primary and substitute parts should account for the following parameter differences:

The SSF-LXH250IID operates at reduced current (20mA vs. 30mA) and lower luminous intensity (40mcd vs. 300mcd), resulting in lower power consumption and reduced brightness output. The substitute part operates at slightly higher voltage (2V vs. 1.85V) and features a marginally larger lens diameter (5mm vs. 4.80mm). The wavelength difference (635nm vs. 660nm) represents a shift toward orange-red spectrum.

Compliance Assurance: Both parts maintain identical regulatory standing with RoHS3 compliance, unlimited moisture sensitivity tolerance, and REACH Unaffected status, ensuring no compliance-related restrictions on substitution.

Frequently Asked Questions (FAQ)

Q: Can the SSF-LXH250IID directly replace the WP73EB/2SRDA in existing circuit board designs?

A: The SSF-LXH250IID maintains compatible mounting type (through-hole, right-angle), configuration (2 High Red x 2), lens characteristics (diffused, tinted, round domed top), and viewing angle (60°). However, the larger lens diameter (5mm vs. 4.80mm) requires verification of PCB layout clearance. The reduced luminous intensity (40mcd vs. 300mcd) and lower operating current (20mA vs. 30mA) may affect visual brightness perception in the application.

Q: What are the key electrical differences between these parts?

A: The WP73EB/2SRDA operates at 1.85V and 30mA, while the SSF-LXH250IID operates at 2V and 20mA. The primary part delivers 300mcd brightness; the substitute delivers 40mcd. These differences reflect distinct design approaches within the dual-level red LED indicator category and require circuit design verification for compatibility.

Q: Are both parts suitable for high-reliability applications?

A: Both parts maintain Active product status with RoHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, indicating suitability for standard industrial and commercial applications. Specific high-reliability requirements should be evaluated against detailed datasheets and application-specific environmental conditions.

Q: What packaging considerations apply to these substitutes?

A: The WP73EB/2SRDA is supplied in standard packaging; the SSF-LXH250IID is supplied in Bulk packaging. Packaging format does not affect component functionality but may influence procurement quantity requirements and handling procedures.

Q: How do the wavelength specifications affect color perception?

A: The WP73EB/2SRDA operates at 660nm (deep red); the SSF-LXH250IID operates at 635nm (orange-red). While both are classified as red LEDs, the wavelength difference produces a perceptible color shift. Application requirements for specific red hue should be verified before substitution.

Q: Are there any regulatory restrictions on using the substitute part?

A: No regulatory restrictions apply. Both parts maintain identical REACH Unaffected status and RoHS3 compliance, ensuring unrestricted substitution from a regulatory perspective.
