LED CBI T-1 Yellow Right Angle 5321F7 Equivalent & Substitute Parts

Part Overview

The 5321F7 is a circuit board indicator LED manufactured by Visual Communications Company (VCC) in the 5321 series. This component is a single yellow diffused LED with a round domed top lens, designed for through-hole right-angle mounting applications. The part operates at 2.1V with a 10mA current rating and produces 6.3 millicandela of light output at a peak wavelength of 585nm.

The 5321F7 carries an obsolete product status. Locating equivalent substitute components is necessary to support ongoing maintenance, repair, and production requirements for legacy equipment and systems utilizing this LED indicator.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5321F7 are identified based on the following critical parameters that determine functional compatibility:

Electrical Compatibility Parameters:

• Color: Yellow (visual indication consistency)
• Voltage Rating: 2.1V (forward voltage match)
• Configuration: Single LED (functional equivalence)
• Mounting Type: Through Hole, Right Angle (mechanical fit)

Optical Compatibility Parameters:

• Lens Type: Diffused, Tinted (light diffusion characteristics)
• Lens Style: Round with Domed Top (physical appearance and light distribution)

Environmental & Regulatory Parameters:

• RoHS3 Compliance (regulatory requirement match)
• REACH Unaffected status (regulatory requirement match)
• Moisture Sensitivity Level 1 (environmental tolerance match)

The substitute part WP934ZH/YD from Kingbright satisfies all critical compatibility parameters. While this substitute exhibits higher current rating (30mA versus 10mA) and higher millicandela output (15mcd versus 6.3mcd), these parameters represent enhanced performance characteristics that do not prevent substitution in applications designed for the original 5321F7. The substitute maintains identical voltage rating, lens characteristics, mounting configuration, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The WP934ZH/YD from Kingbright is an active production substitute for the obsolete 5321F7. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications requiring these certifications.

The substitute part carries active product status, providing assured long-term availability and supply chain continuity compared to the obsolete 5321F7. Both components share identical voltage ratings (2.1V), lens characteristics (diffused, tinted, round domed top), and mounting configuration (through hole, right angle), ensuring mechanical and electrical compatibility in circuit board applications.

The WP934ZH/YD operates at higher current capacity (30mA versus 10mA) and produces greater light output (15mcd versus 6.3mcd). These enhanced performance characteristics do not create substitution barriers; rather, they provide operational margin in applications where the original 5321F7 was specified. Circuit designs utilizing current-limiting resistors will accommodate the substitute without modification, as the higher current rating represents maximum capability rather than a required operating point.

Frequently Asked Questions (FAQ)

Q: Can the WP934ZH/YD directly replace the 5321F7 in existing circuit board designs?

A: Yes. Both components share identical voltage ratings (2.1V), lens types (diffused, tinted), lens styles (round domed top), and mounting configurations (through hole, right angle). The substitute will function in any application designed for the original 5321F7.

Q: What is the significance of the higher current rating in the WP934ZH/YD?

A: The WP934ZH/YD is rated for 30mA maximum current, compared to 10mA for the 5321F7. This represents the maximum current the substitute can safely handle. Existing circuit designs using current-limiting resistors will operate the substitute at the same current level as the original part, typically 10mA or less, without requiring design changes.

Q: Are there differences in light output between these components?

A: The WP934ZH/YD produces 15 millicandela compared to 6.3 millicandela for the 5321F7. The substitute provides brighter light output. In applications where the original brightness was adequate, the increased output of the substitute will remain acceptable. Applications requiring specific brightness levels should evaluate the substitute's output against design requirements.

Q: Do both components meet the same regulatory requirements?

A: Yes. Both the 5321F7 and WP934ZH/YD are ROHS3 compliant and REACH unaffected. They meet identical regulatory standards for hazardous substance restrictions and environmental compliance.

Q: What is the difference between the peak wavelengths (585nm versus 590nm)?

A: Both wavelengths fall within the yellow spectrum and are visually indistinguishable to the human eye. The 5nm difference represents a minor variation in the exact shade of yellow light produced. Both components are suitable for yellow indicator applications.

Q: Why is the 5321F7 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The WP934ZH/YD, carrying active product status, ensures continued availability for applications requiring yellow circuit board indicator LEDs with identical electrical and mechanical characteristics.

Q: Are there any mounting or footprint differences between these components?

A: Both components use through-hole, right-angle mounting. The 5321F7 is specified as T-1 lens size, while the WP934ZH/YD is specified as 3mm, T-1. Both designations refer to the same standard LED package size used in through-hole applications. No PCB layout modifications are required for substitution.
