LED BLUE 3MM ROUND T/H LB3803X Equivalent & Substitute Parts

Part Overview

The LB3803X is a blue LED indicator light manufactured by Stanley Electric Co, designed for through-hole mounting applications. This component is classified as an LED Indication discrete radial device with a 3mm round form factor. The product status is listed as Obsolete, making identification of functionally equivalent substitute components necessary for ongoing design support, maintenance, and production continuity. Obsolete status indicates the part is no longer manufactured or supported by the original supplier, requiring engineers to identify active alternative components that maintain electrical and mechanical compatibility with existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the LB3803X are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Mounting Type: Through Hole (radial configuration required)
• Lens Size: 3mm form factor
• Color: Blue wavelength emission
• Package Configuration: Radial lead arrangement
• Application Class: LED Indication - Discrete

The substitute part WP710A10QBC/D from Kingbright satisfies these core requirements. Both components share identical mounting methodology (through-hole radial), identical lens size classification (3mm T-1 form factor), and identical color specification (blue). The radial package configuration ensures mechanical compatibility with existing PCB footprints designed for the LB3803X. Both components are classified under HTSUS code 8541.41.0000 and maintain REACH Unaffected status, confirming regulatory alignment.

The WP710A10QBC/D is an active product with current manufacturing support, addressing the obsolescence status of the LB3803X while maintaining the electrical and mechanical interface requirements of the original design.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The LB3803X is classified as Obsolete, indicating discontinued manufacturing and unavailable supplier support. The WP710A10QBC/D is an Active product with current manufacturing availability and ongoing supplier support, making it the appropriate selection for new designs and long-term production continuity.

Regulatory and Compliance Alignment: Both components maintain identical REACH Unaffected status and EAR99 ECCN classification, confirming regulatory compatibility. Both fall under the same HTSUS commodity code (8541.41.0000), indicating equivalent trade classification.

Mechanical and Electrical Interface: The WP710A10QBC/D maintains through-hole radial mounting configuration identical to the LB3803X, ensuring direct PCB footprint compatibility. The 3mm T-1 lens size matches the original 3mm round specification, confirming mechanical interchangeability.

Inventory and Supply Chain: The WP710A10QBC/D has 29,696 pieces in current stock with active product status, providing reliable supply chain access. The LB3803X, while showing 1,013 pieces in inventory, carries obsolete status with no future manufacturing support.

For applications currently using the LB3803X, transition to the WP710A10QBC/D is supported by matching mechanical form factor, identical mounting methodology, and active manufacturing status.

Frequently Asked Questions (FAQ)

Q: Can the WP710A10QBC/D be used as a direct replacement for the LB3803X in existing circuit designs?

A: Yes. Both components share identical through-hole radial mounting configuration and 3mm lens size, confirming mechanical footprint compatibility. The WP710A10QBC/D maintains the same package classification and mounting interface required by designs originally specified for the LB3803X.

Q: What are the key differences between these two components?

A: The primary difference is product status: the LB3803X is Obsolete with no ongoing manufacturing support, while the WP710A10QBC/D is Active with current supplier availability. The WP710A10QBC/D provides specified electrical parameters (3.3V forward voltage, 20mA test current, 1600mcd brightness, 465nm dominant wavelength) that were not documented for the LB3803X. Both components maintain identical regulatory compliance (REACH Unaffected, EAR99 classification).

Q: Are there any mechanical compatibility concerns when substituting the WP710A10QBC/D for the LB3803X?

A: No mechanical compatibility concerns exist. Both components use radial through-hole mounting with 3mm lens form factor. The WP710A10QBC/D maximum height of 5.90mm and 2.90mm diameter fall within standard 3mm LED specifications, ensuring compatibility with existing PCB layouts and mechanical assemblies designed for the LB3803X.

Q: What is the significance of the T-1 designation on the WP710A10QBC/D?

A: T-1 is the standard industry designation for 3mm round LED packages. This confirms the WP710A10QBC/D uses the same physical form factor as the LB3803X, ensuring direct mechanical interchangeability in through-hole applications.

Q: Are regulatory certifications identical between these components?

A: Yes. Both the LB3803X and WP710A10QBC/D maintain REACH Unaffected status and EAR99 ECCN classification. Both are classified under HTSUS code 8541.41.0000, confirming equivalent regulatory and trade compliance.

Q: Why is the WP710A10QBC/D recommended over the LB3803X?

A: The WP710A10QBC/D is recommended because it is an Active product with current manufacturing support and available inventory (29,696 pieces). The LB3803X is Obsolete with no future manufacturing availability. For production continuity and long-term supply chain reliability, the active substitute is the appropriate engineering selection.
