OVSABBC2R8 Equivalent & Substitute Parts

Part Overview

The OVSABBC2R8 is a blue 470nm LED indication component in a 4-PLCC surface mount package, rated at 3.9V forward voltage with 200mcd luminous intensity. This part is classified as obsolete, making substitute components necessary for new designs and ongoing production requirements. The obsolete status necessitates identification of functionally equivalent active alternatives that maintain compatibility with existing circuit designs while meeting current supply chain availability.

Substitute Part Grouping Explanation

Substitution of the OVSABBC2R8 is determined by the following critical parameters:

  • Wavelength - Dominant: Must remain 470nm to maintain blue color specification
  • Mounting Type: Must be surface mount to ensure PCB compatibility
  • Viewing Angle: Must be 120° to preserve optical performance characteristics
  • RoHS Compliance: Must maintain ROHS3 compliance for regulatory alignment
  • Voltage - Forward (Vf): Acceptable range within circuit design tolerance (3.6V to 3.9V)
  • Millicandela Rating: Must support minimum 200mcd for indication functionality
  • Physical Dimensions: Must fit within PCB footprint constraints (3.20mm L x 2.80mm W, 1.95mm height maximum)

The OVSA1BBC2R8 qualifies as a direct substitute based on matching wavelength, mounting type, viewing angle, compliance certifications, and physical envelope specifications.

Engineering Selection Recommendations

The OVSA1BBC2R8 is the manufacturer-recommended substitute for the obsolete OVSABBC2R8. Both components maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected) and equivalent regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000).

The OVSA1BBC2R8 offers active product status with significantly higher inventory availability (20,032 pcs in stock versus 857 pcs for the obsolete part). The substitute maintains critical optical and electrical parameters: identical 470nm wavelength, 120° viewing angle, and 30mA test current. Physical dimensions remain compatible with existing PCB layouts (3.20mm L x 2.70mm W versus 3.20mm L x 2.80mm W, with identical 1.95mm maximum height).

The forward voltage differential (3.6V versus 3.9V) represents a 0.3V reduction, which falls within typical circuit design tolerance margins for LED indication applications. The increased millicandela rating (550mcd versus 200mcd) provides enhanced luminous intensity without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can the OVSA1BBC2R8 directly replace the OVSABBC2R8 in existing designs?

A: Yes. Both components share identical wavelength (470nm), viewing angle (120°), mounting type (surface mount), physical height (1.95mm maximum), and compliance certifications. The 0.3V forward voltage reduction and increased luminous intensity are within acceptable parameters for LED indication circuits.

Q: What is the significance of the package designation change from 4-PLCC to 4-SMD, J-Lead?

A: Both designations refer to 4-lead surface mount packages with compatible footprints. The physical dimensions (3.20mm length, approximately 2.7-2.8mm width, 1.95mm height) remain compatible with existing PCB layouts designed for the original component.

Q: How does the increased millicandela rating (550mcd versus 200mcd) affect circuit operation?

A: The higher luminous intensity provides brighter indication at identical test current (30mA). Existing current-limiting resistor values will produce increased brightness. Circuit designs requiring the original 200mcd specification should verify that the enhanced brightness is acceptable for the application.

Q: Are there any moisture sensitivity or handling differences between these components?

A: Both components share identical moisture sensitivity level (MSL 5A, 24 Hours) and require equivalent handling procedures during storage, transport, and assembly.

Q: Why is the OVSABBC2R8 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The OVSA1BBC2R8 represents the active replacement in the manufacturer's product line, offering improved specifications and ongoing supply chain support.
