Key Parameters

Substitute Part Grouping Explanation

Substitution of the OVSASBC2R8 is determined by the following critical parameters:

Electrical Compatibility: Forward voltage (2.4V–2.5V range), test current (50mA), and wavelength classification (red spectrum, 624nm–628nm) establish functional equivalence for indication applications.

Mechanical Compatibility: Surface mount mounting type, 4-PLCC package designation, and physical dimensions (3.20mm length, approximately 2.70mm–2.80mm width, 1.95mm maximum height) ensure PCB layout and assembly process compatibility.

Regulatory Compliance: ROHS3 compliance, MSL 5A rating, and REACH unaffected status maintain environmental and supply chain requirements.

Brightness Consideration: The substitute part OVSA1SBC2R8 provides 1600mcd versus the original 900mcd, representing a higher brightness output within the same package and electrical operating parameters.

The OVSA1SBC2R8 qualifies as a direct substitute based on these aligned parameters, with the primary distinction being enhanced luminous intensity and active product status.

Parameter Comparison

Engineering Selection Recommendations

The OVSA1SBC2R8 is the designated substitute for the obsolete OVSASBC2R8. Selection is supported by the following factors:

Product Status: The substitute maintains active manufacturing status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Regulatory Alignment: Both components maintain ROHS3 compliance and identical MSL ratings, preserving environmental and manufacturing process requirements without modification.

Electrical Operating Range: The forward voltage differential (2.4V versus 2.5V) and identical test current (50mA) fall within standard circuit design tolerances for LED indication circuits. The wavelength shift from 628nm to 624nm remains within the red spectrum classification and does not affect functional performance in indication applications.

Physical Compatibility: Dimensional alignment (3.20mm length, 1.95mm maximum height) and surface mount configuration enable direct PCB layout compatibility. The 0.1mm width reduction (2.80mm to 2.70mm) does not impact assembly or thermal performance.

Brightness Enhancement: The increased luminous intensity (1600mcd versus 900mcd) provides improved visibility margin in indication applications without requiring circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can OVSA1SBC2R8 be used as a direct replacement for OVSASBC2R8 in existing designs?

A: Yes. Both components share identical mounting type (surface mount), package classification (4-PLCC), physical dimensions within tolerance, forward voltage within standard operating range, and test current specification. PCB layout and assembly processes require no modification.

Q: What is the significance of the wavelength difference (628nm to 624nm)?

A: Both wavelengths fall within the red spectrum classification for LED indication. The 4nm difference does not affect functional performance in standard indication applications and is within the tolerance range of human color perception for red LEDs.

Q: Does the higher brightness rating (1600mcd versus 900mcd) require circuit modifications?

A: No. The substitute operates at the same test current (50mA) and forward voltage range (2.4V). Existing current-limiting resistor values and power supply configurations remain valid. The increased brightness provides enhanced visibility without additional design changes.

Q: Are there packaging differences between the original and substitute?

A: The original is designated 4-PLCC; the substitute is designated 4-SMD, J-Lead. Both are surface mount packages with identical physical dimensions and mounting compatibility. The J-Lead designation refers to the lead configuration within the same 4-PLCC footprint.

Q: What is the inventory status of the substitute part?

A: OVSA1SBC2R8 has 129,043 pieces in stock as new original inventory, providing substantial supply availability compared to the obsolete original part.

Q: Are compliance certifications maintained with the substitute?

A: Yes. OVSA1SBC2R8 maintains ROHS3 compliance, MSL 5A (24 Hours) rating, and REACH unaffected status identical to the original component.
