CSL0406WBCW1 Equivalent & Substitute Parts

Part Overview

The CSL0406WBCW1 is a white diffused LED in 2812 SMD packaging manufactured by Rohm Semiconductor. This component is classified as obsolete, with 1897 units currently in stock. The part is designed for white LED indication applications with a forward voltage of 3.2V and a brightness rating of 2200mcd at 20mA test current. Due to its obsolete status, identifying equivalent substitute parts is essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSL0406WBCW1 is determined by the following critical parameters:

• Color: White
• Voltage - Forward (Vf): 3.2V
• Current - Test: 20mA
• Millicandela Rating: 2200mcd
• Package / Case: 2-SMD, J-Lead
• Supplier Device Package: 2812
• Size / Dimension: 2.45mm L x 1.20mm W
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

The CSL0416WBCW1 qualifies as a substitute part because it maintains electrical equivalence in forward voltage, test current, and brightness rating. Both parts share identical package dimensions, RoHS compliance, and MSL specifications. Differences in lens color, lens transparency, mounting configuration, and product status do not prevent functional substitution in applications where the primary requirement is white LED indication at the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The CSL0416WBCW1 is the designated substitute for the obsolete CSL0406WBCW1. Both parts maintain electrical equivalence with identical forward voltage (3.2V), test current (20mA), and brightness output (2200mcd). Both components are ROHS3 compliant and share identical MSL specifications, ensuring compatibility with standard surface mount assembly processes.

The primary distinction is product status: the CSL0406WBCW1 is obsolete with limited remaining inventory (1897 units), while the CSL0416WBCW1 is active with current availability (1946 units). The CSL0416WBCW1 features right-angle mounting and a slightly increased maximum height (0.90mm versus 0.80mm), which must be evaluated against specific PCB layout constraints. For applications where the 0.10mm height difference or right-angle configuration presents a design conflict, the CSL0416WBCW1 remains electrically suitable but may require PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the CSL0416WBCW1 directly replace the CSL0406WBCW1 in existing designs?

A: Electrical substitution is valid. Both parts operate at 3.2V forward voltage with 2200mcd brightness at 20mA. Physical compatibility depends on PCB layout: the CSL0416WBCW1 has a maximum height of 0.90mm compared to 0.80mm for the CSL0406WBCW1, and features right-angle mounting versus standard surface mount. Verify clearance and mounting orientation requirements before implementation.

Q: Are there compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and carry identical MSL ratings of 3 (168 Hours). No compliance barriers exist for substitution.

Q: What is the impact of the mounting type difference?

A: The CSL0406WBCW1 uses standard surface mount configuration, while the CSL0416WBCW1 uses right-angle mounting. This affects component orientation on the PCB and may require layout modification. Confirm mounting requirements with your PCB design before selecting the substitute.

Q: Why is the CSL0406WBCW1 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The CSL0416WBCW1 is the active equivalent, ensuring long-term supply chain continuity for white LED indication applications at these electrical specifications.
