Key Parameters

Substitute Part Grouping Explanation

Substitution of the QLA694B2G is determined by the following critical parameters that must align for functional equivalence:

• Physical Form Factor: 3mm T-1 lens size with round domed top, through-hole right-angle mounting
• Electrical Configuration: 2 High dual-level LED assembly
• Voltage Compatibility: 2.1V operating voltage
• Lens Characteristics: Diffused, tinted optical properties
• Regulatory Compliance: REACH Unaffected status and EAR99 ECCN classification

The substitute part WP934EB/2YD from Kingbright shares identical mechanical mounting, lens form factor, voltage rating, and configuration structure. However, this substitute differs in color specification (yellow vs. green) and electrical current rating (20mA vs. 10mA), which may require circuit design evaluation for direct replacement scenarios.

Parameter Comparison

Engineering Selection Recommendations

The WP934EB/2YD from Kingbright is an active product with current manufacturing support and ROHS3 compliance, providing supply chain continuity for the obsolete QLA694B2G. Both components share identical mechanical interfaces, voltage specifications, and regulatory compliance status.

Selection of WP934EB/2YD requires evaluation of the following design factors: the 20mA current specification versus the original 10mA rating necessitates circuit current-limiting verification; the yellow color output differs from the original green specification and may affect visual indication requirements; the 11.5mcd brightness rating exceeds the original 6mcd specification, which may require optical masking or circuit attenuation if brightness consistency is critical to the application.

Frequently Asked Questions (FAQ)

Q: Can WP934EB/2YD directly replace QLA694B2G without circuit modification?

A: Physical and electrical mounting compatibility is confirmed. However, the 20mA current rating and yellow color output require design review. Circuit current-limiting resistor values may require adjustment to accommodate the higher current specification.

Q: What are the key compatibility criteria for this LED indicator substitution?

A: Mechanical compatibility is ensured through identical 3mm T-1 through-hole right-angle form factor and round domed top lens style. Electrical compatibility is established through matching 2.1V voltage rating and 2 High configuration. Optical compatibility depends on application tolerance for color and brightness differences.

Q: Are there regulatory or compliance concerns with this substitution?

A: Both components maintain REACH Unaffected status and EAR99 ECCN classification. The substitute part carries ROHS3 compliance, providing enhanced regulatory alignment for new designs.

Q: How do the brightness specifications compare?

A: The WP934EB/2YD provides 11.5mcd versus the original 6mcd rating. This increased brightness may require optical filtering or circuit current reduction if the application requires matching the original light output intensity.

Q: What packaging considerations apply to this substitution?

A: The original QLA694B2G is supplied in standard packaging. The WP934EB/2YD is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.
