LED Circuit Board Indicator 5321F5 Equivalent & Substitute Parts

Part Overview

The VCC 5321F5 is a green circuit board indicator LED featuring a T-1 form factor with right-angle through-hole mounting. This component delivers 16 millicandela output at 10mA forward current with a 2.2V forward voltage rating. The device utilizes a diffused, tinted lens with round domed top geometry optimized for circuit board integration applications.

The 5321F5 is classified as obsolete. Locating equivalent substitute components is necessary to support ongoing production requirements, field repairs, and design continuity for systems currently utilizing this LED indicator.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the 5321F5 must satisfy the following criteria based on provided electrical and mechanical parameters:

Mandatory Matching Parameters:

• Color: Green
• Mounting Type: Through Hole, Right Angle
• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top
• Configuration: Single
• Voltage Rating: 2.2V
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variations:

• Lens Size: T-1 or 3mm (both compatible with standard through-hole circuit board patterns)
• Current Rating: May exceed 10mA (higher current capability does not prevent substitution; circuit design accommodates via current-limiting resistor adjustment)
• Millicandela Rating: May exceed 16mcd (increased brightness is functionally compatible)
• Wavelength - Peak: Minor variation acceptable within green spectrum range (562nm to 565nm)
• Viewing Angle: Addition of specified viewing angle parameter does not prevent substitution

The Kingbright WP934ZH/GD meets all mandatory matching criteria and falls within allowable parameter variation ranges.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility: The Kingbright WP934ZH/GD is a direct functional substitute for the VCC 5321F5 based on electrical and mechanical parameter alignment.

Compliance Basis: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

Product Availability: The 5321F5 is obsolete with limited inventory (668 pieces). The WP934ZH/GD is active production with substantial inventory availability (5736 pieces), ensuring supply chain continuity.

Circuit Design Consideration: The WP934ZH/GD is rated for 25mA maximum forward current compared to the 5321F5 at 10mA. Existing circuit designs using current-limiting resistors sized for 10mA operation remain valid; the substitute component will operate at the same current level determined by the resistor value. No circuit modification is required for direct substitution.

Brightness Performance: The WP934ZH/GD delivers 30 millicandela versus 16 millicandela for the 5321F5. This increased brightness is functionally compatible with applications requiring circuit board indicator visibility.

Frequently Asked Questions (FAQ)

Q: Can the Kingbright WP934ZH/GD replace the VCC 5321F5 in existing circuit designs without modification?

A: Yes. Both components share identical voltage ratings (2.2V), mounting type (through-hole right-angle), lens configuration (diffused tinted round domed top), and form factor (T-1). Existing current-limiting resistor values remain valid. The substitute operates at the same forward current determined by circuit resistor design.

Q: What is the significance of the 3mm designation on the WP934ZH/GD?

A: The 3mm specification indicates the physical diameter of the lens. Both the 5321F5 and WP934ZH/GD are T-1 form factor components compatible with standard through-hole circuit board patterns. The 3mm measurement is a dimensional specification that does not affect substitution compatibility.

Q: Why does the WP934ZH/GD have a higher current rating (25mA) than the 5321F5 (10mA)?

A: The 25mA rating represents the maximum forward current the Kingbright component can safely handle. In substitution applications, the actual operating current is determined by the circuit's current-limiting resistor, not the component's maximum rating. If the original circuit uses a resistor sized for 10mA operation, the substitute will operate at 10mA.

Q: Are there wavelength differences between the two components?

A: The 5321F5 has a peak wavelength of 562nm while the WP934ZH/GD is specified at 565nm. This 3nm variation falls within the green spectrum range and produces no perceptible difference in color appearance for circuit board indicator applications.

Q: What is the viewing angle specification on the WP934ZH/GD?

A: The WP934ZH/GD specifies a 40-degree viewing angle. This parameter defines the angular range within which the LED maintains specified brightness performance. The 5321F5 does not provide a viewing angle specification, but both components use identical diffused tinted lens geometry suitable for general circuit board indicator applications.

Q: Are both components RoHS compliant?

A: Yes. Both the VCC 5321F5 and Kingbright WP934ZH/GD are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the inventory status difference between these components?

A: The 5321F5 is classified as obsolete with 668 pieces available. The WP934ZH/GD is active production with 5736 pieces in stock. For new production or long-term supply requirements, the active component ensures sustained availability.
