OVLAW4CB6 White LED 3MM Through-Hole Equivalent & Substitute Parts

Part Overview

The OVLAW4CB6 is a white LED indicator light manufactured by TT Electronics/Optek Technology, designed for through-hole mounting in 3mm form factor applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The OVLAW4CB6 delivers 1000mcd brightness at 3.4V forward voltage with a 45° viewing angle, suitable for standard indication applications requiring discrete white LED functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OVLAW4CB6 is determined by the following electrical and mechanical compatibility criteria:

Primary Substitution Parameters:

• Color: White
• Lens Size: 3.00mm Dia (±0.05mm tolerance acceptable)
• Mounting Type: Through Hole Radial
• Lens Style: Round with Domed Top
• Viewing Angle: 45°
• Current - Test: 20mA
• Voltage - Forward (Vf): 3.2V to 4.6V range
• Millicandela Rating: 1000mcd minimum
• Height (Max): 5.00mm to 5.85mm
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The OVLAW4CB6 has two qualified substitutes: OVLAW4CB7 from the same manufacturer (TT Electronics/Optek Technology) and 5219901802F from Dialight. Both maintain electrical compatibility within the specified forward voltage and brightness parameters while preserving mechanical fit in standard 3mm LED mounting applications.

Parameter Comparison

Engineering Selection Recommendations

OVLAW4CB7 Selection Criteria: The OVLAW4CB7 is the primary substitute for the OVLAW4CB6. Both parts are manufactured by TT Electronics/Optek Technology, ensuring design continuity. The OVLAW4CB7 is currently in active production status, providing long-term availability. Forward voltage is 3.2V compared to 3.4V in the original part, representing a 0.2V reduction within acceptable circuit design margins. The OVLAW4CB7 delivers 6200mcd brightness, significantly exceeding the 1000mcd specification of the OVLAW4CB6. Lens diameter increases from 3.00mm to 3.05mm and height from 5.00mm to 5.20mm, both within standard mechanical tolerances for 3mm LED mounting footprints. The OVLAW4CB7 carries ROHS3 compliance certification.

5219901802F Selection Criteria: The 5219901802F from Dialight serves as an alternative substitute when OVLAW4CB7 availability is constrained. This part maintains the exact 3.00mm lens diameter and 45° viewing angle of the original OVLAW4CB6. Forward voltage is 4.6V, representing a 0.1V increase from the original specification. Brightness is 1100mcd, closely matching the 1000mcd rating of the OVLAW4CB6. Height reaches 5.85mm maximum, the highest among the three options but still compatible with standard 3mm LED mounting applications. The 5219901802F carries ROHS3 compliance certification and belongs to the Dialight 521 series.

Compliance and Availability: Both substitute parts maintain REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited) classification, matching the original part's environmental specifications. Both substitutes are ROHS3 compliant, exceeding the compliance profile of the obsolete OVLAW4CB6. Current inventory levels are 41,492 units for OVLAW4CB7 and 6,103 units for 5219901802F, ensuring procurement viability for production applications.

Frequently Asked Questions (FAQ)

Q: Can OVLAW4CB7 be used as a direct replacement for OVLAW4CB6 in existing designs? A: Yes. The OVLAW4CB7 maintains electrical compatibility within the 20mA test current specification and operates within acceptable forward voltage variance (3.2V vs. 3.4V). Mechanical fit is preserved through compatible 3mm radial through-hole mounting. The increased brightness (6200mcd vs. 1000mcd) may require circuit-level current limiting adjustment if the original design relied on the lower brightness specification.

Q: What are the mechanical differences between these three parts? A: Lens diameter varies slightly: OVLAW4CB6 and 5219901802F both measure 3.00mm, while OVLAW4CB7 measures 3.05mm. Height differences are: OVLAW4CB6 at 5.00mm maximum, OVLAW4CB7 at 5.20mm maximum, and 5219901802F at 5.85mm maximum. All three maintain round domed-top lens geometry and radial through-hole mounting compatibility.

Q: How do forward voltage differences affect circuit design? A: The three parts operate at 3.4V (OVLAW4CB6), 3.2V (OVLAW4CB7), and 4.6V (5219901802F). These variations fall within typical white LED forward voltage tolerance bands. Circuit designs using series current-limiting resistors will accommodate these differences automatically. Designs with voltage-dependent brightness control may require resistor value adjustment to maintain consistent brightness output.

Q: Are both substitute parts ROHS compliant? A: Yes. Both OVLAW4CB7 and 5219901802F carry ROHS3 compliance certification. The original OVLAW4CB6 does not specify RoHS status. Both substitutes also maintain REACH Unaffected status matching the original part.

Q: Which substitute should be selected for new production designs? A: OVLAW4CB7 is the recommended primary choice due to same-manufacturer sourcing from TT Electronics/Optek Technology, higher current inventory (41,492 units), and active production status. The 5219901802F serves as a secondary option when OVLAW4CB7 availability is limited, offering closer brightness matching to the original specification (1100mcd vs. 6200mcd).

Q: Do these parts fit the same PCB footprint? A: Yes. All three parts use 3mm radial through-hole mounting with compatible lead spacing. Mechanical height variations (5.00mm to 5.85mm) do not affect PCB footprint compatibility but may impact clearance in space-constrained applications. Verify available vertical clearance in your specific assembly design.
