WP73EB/2IDA LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The WP73EB/2IDA is an active LED circuit board indicator manufactured by Kingbright, configured as a dual-level red LED assembly. This component is designed for through-hole, right-angle mounting applications requiring a 4.80mm diameter diffused lens with domed top. The part operates at 2V with a 30mA current rating and delivers 40mcd brightness output at a 60° viewing angle. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WP73EB/2IDA are identified based on strict equivalence in the following critical parameters:

Electrical Compatibility Parameters:

• Dual-level (2 High) configuration maintained
• Voltage rating of 2V maintained
• Millicandela output of 40mcd maintained
• Red color specification maintained

Mechanical Compatibility Parameters:

• Through-hole, right-angle mounting maintained
• Round lens with domed top maintained
• Diffused, tinted lens type maintained

Compliance Parameters:

• ROHS3 compliance maintained
• MSL 1 (Unlimited) maintained
• REACH Unaffected status maintained

The SSF-LXH250IID from Lumex Opto/Components Inc. qualifies as a substitute based on these equivalencies. Variations in current rating (20mA vs. 30mA), lens diameter (5mm vs. 4.80mm), and wavelength peak (635nm vs. 627nm) represent acceptable parameter differences within the allowed substitution criteria for this product category.

Engineering Selection Recommendations

Primary Part: WP73EB/2IDA

The WP73EB/2IDA maintains active product status with 828 units in stock. This component is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The 4.80mm lens diameter and 30mA current specification define the baseline performance envelope for this application.

Substitute Part: SSF-LXH250IID

The SSF-LXH250IID from Lumex Opto/Components Inc. is an active product with 3,063 units in stock. This substitute maintains ROHS3 compliance and REACH unaffected status. The part operates at the same 2V voltage and delivers equivalent 40mcd output at 60° viewing angle with identical dual-level configuration and diffused, tinted lens characteristics.

Selection between these parts is determined by:

1. Mechanical fit requirements: The 5mm lens diameter of the SSF-LXH250IID versus the 4.80mm diameter of the WP73EB/2IDA affects PCB hole sizing and mounting clearance.

2. Current budget constraints: The 20mA rating of the SSF-LXH250IID provides lower power consumption compared to the 30mA rating of the WP73EB/2IDA.

3. Wavelength specification: The 635nm peak wavelength of the SSF-LXH250IID differs from the 627nm peak of the WP73EB/2IDA, affecting perceived color intensity.

4. Inventory availability: Both parts are in active stock with adequate supply.

Both parts satisfy compliance requirements and functional equivalency within the allowed parameter tolerances for dual-level red LED circuit board indicators with through-hole, right-angle mounting.

Frequently Asked Questions (FAQ)

Q: What defines substitution eligibility for the WP73EB/2IDA?

A: Substitutes must maintain the dual-level (2 High) configuration, 2V voltage rating, 40mcd brightness output, 60° viewing angle, diffused tinted lens with domed top, through-hole right-angle mounting, and ROHS3/REACH compliance status. Variations in current rating, lens diameter, and wavelength peak are acceptable within the allowed parameter range for this product category.

Q: Can the SSF-LXH250IID be used in place of the WP73EB/2IDA without PCB redesign?

A: The 5mm lens diameter of the SSF-LXH250IID differs from the 4.80mm diameter of the WP73EB/2IDA. PCB hole sizing and mounting clearance must be evaluated for your specific application. The right-angle through-hole mounting configuration is equivalent between both parts.

Q: What is the impact of the 20mA versus 30mA current difference?

A: The SSF-LXH250IID operates at 20mA while the WP73EB/2IDA operates at 30mA. This represents a 33% reduction in current consumption. Both parts deliver the same 40mcd brightness output, indicating the SSF-LXH250IID achieves equivalent optical performance at lower power draw.

Q: Are there wavelength considerations when substituting?

A: The WP73EB/2IDA has a 627nm peak wavelength while the SSF-LXH250IID has a 635nm peak wavelength. Both are red LEDs within the standard red spectrum. The 8nm difference may result in slightly different perceived color intensity, but both maintain the red color specification for dual-level circuit board indicator applications.

Q: Do both parts meet current regulatory compliance?

A: Yes. Both the WP73EB/2IDA and SSF-LXH250IID are ROHS3 compliant and REACH unaffected. Both maintain MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard storage and handling conditions.

Q: What packaging considerations apply to these parts?

A: The WP73EB/2IDA is supplied in standard packaging. The SSF-LXH250IID is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.
