WP934FG/2ID Equivalent & Substitute Parts

Part Overview

The WP934FG/2ID is a dual-level red LED circuit board indicator manufactured by Kingbright. This through-hole, right-angle mounted component features a 3mm diffused lens with domed top, designed for 2V operation at 30mA. The part is Active status and ROHS3 compliant, making it suitable for current production applications. Substitute parts are identified when inventory constraints, packaging requirements, or specific application parameters necessitate alternative sourcing options while maintaining functional compatibility.

Substitute Part Grouping Explanation

Substitute parts for the WP934FG/2ID are classified into two categories based on compatibility criteria:

Direct Substitute (WP934MD/2ID): This Kingbright part maintains identical electrical and mechanical specifications across all critical parameters: 2V voltage rating, 30mA current, 627nm wavelength, 30mcd brightness, 40° viewing angle, 3mm T-1 lens size, and through-hole right-angle mounting. The only difference is packaging format (Bulk versus standard). This part is interchangeable in all applications where WP934FG/2ID is specified.

Similar Substitute (SSF-LXH240GGD): This Lumex Opto/Components Inc. part shares the same mounting type (through-hole, right-angle), lens style (round with domed top), configuration (2 High), and compliance certifications (ROHS3, REACH Unaffected). However, it differs in color (green versus red), wavelength (565nm versus 627nm), lens size (2.90mm versus 3mm), voltage rating (2.2V versus 2V), current (20mA versus 30mA), brightness (40mcd versus 30mcd), and viewing angle (60° versus 40°). This part is suitable only for applications where red color is not a functional requirement and the electrical parameter variations are acceptable.

Parameter Comparison

Engineering Selection Recommendations

WP934MD/2ID Selection: This direct substitute is recommended when WP934FG/2ID inventory is unavailable or when bulk packaging is preferred. All electrical parameters, mechanical dimensions, and compliance certifications are identical. No circuit redesign or application modification is required. Both parts are Active status with ROHS3 compliance and REACH Unaffected designation.

SSF-LXH240GGD Selection: This similar substitute is applicable only in applications where the following conditions are met: (1) LED color indication is not functionally critical or green indication is acceptable in place of red, (2) the circuit can accommodate 2.2V operation instead of 2V, (3) the reduced current draw of 20mA versus 30mA is compatible with the application, (4) the slightly smaller lens diameter (2.90mm versus 3mm) fits the mechanical envelope, and (5) the wider viewing angle (60° versus 40°) does not create unintended visibility issues. This part maintains equivalent compliance status and mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can WP934MD/2ID be used as a direct replacement for WP934FG/2ID without any circuit modifications?

A: Yes. WP934MD/2ID is a direct substitute with identical electrical specifications (2V, 30mA), optical characteristics (627nm, 30mcd, 40° viewing angle), and mechanical dimensions (3mm T-1 through-hole right-angle). The only difference is packaging format. No circuit modifications are required.

Q: What are the key differences between WP934FG/2ID and SSF-LXH240GGD?

A: The primary differences are: color (red versus green), wavelength (627nm versus 565nm), voltage rating (2V versus 2.2V), current (30mA versus 20mA), brightness (30mcd versus 40mcd), viewing angle (40° versus 60°), and lens size (3mm versus 2.90mm). These parts share the same mounting type, lens style, configuration, and compliance certifications.

Q: Is SSF-LXH240GGD suitable for applications requiring red LED indication?

A: No. SSF-LXH240GGD is a green LED with 565nm wavelength. It is not suitable for applications requiring red (627nm) indication. Use WP934MD/2ID for red LED requirements.

Q: Can SSF-LXH240GGD operate at 2V like WP934FG/2ID?

A: SSF-LXH240GGD has a 2.2V voltage rating, which is 0.2V higher than WP934FG/2ID. Circuits designed for 2V operation may not provide optimal performance with this part. Verify circuit voltage tolerance before substitution.

Q: Are all three parts ROHS3 compliant?

A: Yes. WP934FG/2ID, WP934MD/2ID, and SSF-LXH240GGD are all ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status.

Q: What is the difference in packaging between WP934FG/2ID and WP934MD/2ID?

A: WP934FG/2ID is supplied in standard packaging, while WP934MD/2ID is supplied in Bulk packaging. Both contain the same component with identical specifications.

Q: Does the 2.90mm lens size of SSF-LXH240GGD fit in a 3mm mounting hole?

A: The 2.90mm lens diameter is slightly smaller than the 3mm specification of WP934FG/2ID. Verify mechanical fit in the specific PCB design before substitution, as the smaller diameter may affect mounting security or visual alignment.
