Key Parameters

Substitute Part Grouping Explanation

Substitution of the QLA694B2I is determined by strict alignment of the following parameters:

• Configuration: 2 High dual-level LED arrangement
• Color: Red (x 2)
• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole, Right Angle
• Voltage Rating: 2V

The WP934EB/2ID from Kingbright satisfies all these core substitution criteria. While the substitute part exhibits higher current (20mA) and brightness (22.5mcd) specifications, these represent enhanced performance characteristics within the same functional category and do not preclude direct substitution in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The WP934EB/2ID is a direct functional substitute for the obsolete QLA694B2I. Both components share identical mechanical form factors, electrical voltage specifications, and mounting configurations. The substitute part maintains active product status, ensuring long-term availability and supply chain continuity.

The WP934EB/2ID demonstrates enhanced electrical performance with doubled current capacity (20mA versus 10mA) and increased brightness output (22.5mcd versus 6mcd). These characteristics represent performance improvements rather than incompatibilities. The substitute part carries ROHS3 compliance certification, providing additional regulatory alignment for modern manufacturing environments.

Both components maintain identical moisture sensitivity ratings and REACH compliance status, confirming environmental and regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the WP934EB/2ID directly replace the QLA694B2I in existing circuit board designs?

A: Yes. Both components share identical mechanical dimensions (3mm T-1 through-hole right-angle configuration), electrical voltage rating (2V), and mounting specifications. Direct PCB substitution is supported without layout modifications.

Q: What is the significance of the higher current rating in the WP934EB/2ID?

A: The WP934EB/2ID operates at 20mA maximum current compared to the QLA694B2I at 10mA. This specification defines the component's maximum safe operating current. Circuits designed for the original 10mA specification remain compatible, as the substitute part can operate at lower current levels. Circuit current-limiting resistors should be verified to ensure they remain appropriate for the application.

Q: Are there compliance differences between these parts?

A: Both components maintain REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited) ratings. The WP934EB/2ID carries additional ROHS3 compliance certification, which represents a regulatory advantage for applications subject to RoHS requirements.

Q: Why is the QLA694B2I classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The WP934EB/2ID, classified as active, ensures continued availability for new production runs and design revisions.

Q: Does the increased brightness of the WP934EB/2ID affect circuit operation?

A: The higher millicandela rating (22.5mcd versus 6mcd) indicates increased light output. In applications where brightness is a functional requirement, this represents an improvement. In applications where brightness is not a limiting factor, the increased output does not negatively impact circuit operation.
