LED Panel Indicator 5110F7 - Equivalent & Substitute Parts

Part Overview

The VCC 5110F7 is a yellow LED panel indicator designed for applications requiring a 2.1V, 30mA illuminated status display with wire lead termination. This component features a 3mm T-1 lens with diffused transparency and a 0.16" (4.06mm) round panel cutout. The 5110F7 carries a "Not For New Designs" product status, indicating that this part is no longer recommended for new development projects. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and transition to active product lines that meet current manufacturing standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5110F7 must satisfy the following core electrical and mechanical criteria to ensure functional compatibility:

Electrical Compatibility Requirements:

• Forward voltage (Vf) of 2.1V (Typ)
• Maximum current (If) of 30mA
• Yellow lamp color for consistent visual indication

Mechanical Compatibility Requirements:

• Round panel cutout shape
• Wire lead termination style
• Diffused lens transparency for uniform light distribution
• Round lens with domed top geometry

Optical Compatibility Requirements:

• Yellow wavelength in the 585nm–590nm range
• Millicandela rating sufficient for panel indication applications

Compliance Requirements:

• ROHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)

The Kingbright WP1533AA/YD-W152 satisfies all core electrical parameters (2.1V, 30mA, yellow) and mechanical requirements (round panel cutout, wire leads, diffused lens, round domed top). Variations in panel cutout diameter (0.25" vs. 0.16"), lens size (4.70mm vs. 3mm), wire lead length (6" vs. 4.4"), millicandela rating (40mcd vs. 6.3mcd), and wavelength peak (590nm vs. 585nm) are within acceptable tolerances for panel indicator applications and do not prevent substitution when mechanical panel modifications are feasible.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The 5110F7 carries a "Not For New Designs" designation, whereas the Kingbright WP1533AA/YD-W152 maintains "Active" product status. For new development projects, the WP1533AA/YD-W152 is the recommended choice to ensure long-term supply availability and manufacturer support.

Compliance and Certification

Both parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), meeting identical environmental and regulatory requirements. No compliance barriers exist for substitution.

Electrical Compatibility

Identical forward voltage (2.1V) and maximum current (30mA) specifications ensure direct electrical substitution without circuit modification. Both parts operate within the same power budget and require identical current-limiting resistor calculations.

Mechanical Considerations

The WP1533AA/YD-W152 requires a 0.25" (6.35mm) panel cutout versus the 5110F7's 0.16" (4.06mm) cutout. Panel modification is necessary for physical installation. The larger 4.70mm lens diameter is proportional to the enlarged cutout and maintains visual consistency. Wire lead length increases from 4.4" to 6", providing additional routing flexibility in panel-mounted applications.

Optical Performance

The WP1533AA/YD-W152 delivers 40mcd brightness compared to the 5110F7's 6.3mcd, representing a 6.3× increase in luminous intensity. This enhanced brightness improves visibility in high-ambient-light environments. Peak wavelength shifts from 585nm to 590nm, remaining within the yellow spectrum with no perceptible color difference in typical applications.

Frequently Asked Questions (FAQ)

Q: Can the WP1533AA/YD-W152 be used as a direct drop-in replacement for the 5110F7?

A: Electrical substitution is direct; no circuit changes are required. Mechanical substitution requires panel modification to accommodate the larger 0.25" (6.35mm) cutout. The 5110F7 uses a 0.16" (4.06mm) cutout, so existing panel holes must be enlarged or the panel redesigned.

Q: What is the impact of the increased millicandela rating (40mcd vs. 6.3mcd)?

A: The WP1533AA/YD-W152 produces significantly brighter illumination. In applications where the original 6.3mcd brightness is adequate, the higher output does not create a functional problem but may require reduced current or series resistor adjustment if visual consistency with other indicators is critical. The diffused lens mitigates excessive brightness concentration.

Q: Are there differences in wavelength that affect color perception?

A: The wavelength shift from 585nm to 590nm remains within the yellow spectrum. Both wavelengths are perceived as yellow by human vision and are suitable for standard status indication applications. No color filter or optical compensation is required.

Q: Why is the wire lead length longer on the substitute part?

A: The WP1533AA/YD-W152 provides 6" (152.40mm) leads versus 4.4" (111.80mm) on the 5110F7. Longer leads offer greater routing flexibility in panel-mounted designs and do not create compatibility issues. Excess lead length can be trimmed if necessary.

Q: What compliance certifications apply to both parts?

A: Both the 5110F7 and WP1533AA/YD-W152 are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). No compliance barriers prevent substitution in regulated applications.

Q: Is the 60° viewing angle of the WP1533AA/YD-W152 a limitation?

A: The 5110F7 does not specify a viewing angle. The 60° specification on the WP1533AA/YD-W152 indicates the angular range within which brightness remains above 50% of peak intensity. This is typical for diffused panel indicators and does not restrict use in standard panel-mounted applications where viewing occurs within normal angles.

Q: What is the product status significance?

A: The 5110F7's "Not For New Designs" status indicates VCC no longer recommends this part for new development. The WP1533AA/YD-W152's "Active" status confirms Kingbright continues manufacturing and supporting this part, ensuring supply chain continuity and technical support availability.
