Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5321F1 is determined by alignment of the following critical parameters:

Mandatory Compatibility Parameters:

• Color: Red
• Configuration: Single
• Voltage Rating: 2V
• Mounting Type: Through Hole, Right Angle
• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters Allowing Substitution:

• Current Rating: The substitute may operate at higher current (30mA vs. 10mA)
• Millicandela Rating: The substitute may deliver higher luminous intensity (30mcd vs. 10mcd)
• Wavelength - Peak: Minor variations within red spectrum acceptable (627nm vs. 650nm)
• Lens Size: T-1 and 3mm are compatible in this product category
• Viewing Angle: The substitute includes specified viewing angle (40°)
• Product Status: Active status preferred for ongoing availability

The Kingbright WP934ZH/ID meets all mandatory parameters while providing enhanced electrical performance characteristics suitable for direct substitution in circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

The Kingbright WP934ZH/ID is a direct substitute for the obsolete Visual Communications Company 5321F1 based on compliance and electrical compatibility. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

The WP934ZH/ID provides enhanced performance characteristics with 30mA current capacity and 30mcd luminous intensity compared to the 5321F1 specifications. The active product status of the WP934ZH/ID ensures long-term availability and supply chain continuity, addressing the obsolescence of the original component.

Both parts share identical voltage rating (2V), mounting configuration (through-hole right angle), and lens characteristics (diffused, tinted, round with domed top). The wavelength variation (627nm versus 650nm) remains within the red spectrum and does not impact functional compatibility in circuit board indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the WP934ZH/ID directly replace the 5321F1 in existing circuit designs?

A: Yes. Both components operate at 2V with identical through-hole right-angle mounting and diffused red lens characteristics. Circuit designs using the 5321F1 can accommodate the WP934ZH/ID without modification to mechanical mounting or electrical interface.

Q: What is the impact of the higher current rating (30mA vs. 10mA) on circuit design?

A: The WP934ZH/ID current rating of 30mA represents the maximum operating specification. Existing circuits designed for 10mA operation of the 5321F1 will operate the WP934ZH/ID at reduced current levels without performance degradation. Current-limiting resistor values in the circuit remain valid for the substitute component.

Q: Are there differences in lens size between these components?

A: The 5321F1 is specified as T-1 lens size. The WP934ZH/ID is specified as 3mm, T-1. Both designations refer to compatible through-hole package dimensions in this product category. Physical mounting compatibility is maintained.

Q: How does the wavelength difference (650nm vs. 627nm) affect visual appearance?

A: Both wavelengths fall within the red spectrum. The 627nm wavelength of the WP934ZH/ID produces a red indication visually consistent with the 650nm specification of the 5321F1 in circuit board indicator applications.

Q: What is the significance of the active product status of the WP934ZH/ID?

A: Active product status indicates current manufacturing and availability through authorized distributors. This ensures supply chain continuity and eliminates the obsolescence risk associated with the 5321F1.

Q: Are both components compliant with current regulatory requirements?

A: Yes. Both the 5321F1 and WP934ZH/ID maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory standards for electronic component manufacturing and distribution.
