Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete OVSAABLCR8 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Color: Amber (591nm dominant wavelength)
• Package / Case: 4-SMD, J-Lead
• Mounting Type: Surface Mount
• Lens Size: 2.60mm Dia
• Viewing Angle: 60°
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 5A (24 Hours)

Allowable Variation Parameters:

• Voltage - Forward (Vf): ±0.1V tolerance acceptable for LED indication circuits
• Millicandela Rating: Higher brightness ratings are acceptable for direct replacement
• Height (Max): ±0.10mm tolerance acceptable within PCB assembly constraints
• Current - Test: Consistent at 50mA test condition

The OVSA1ABLCR8 meets all critical matching parameters and represents the manufacturer-recommended active equivalent for this obsolete part.

Parameter Comparison

Engineering Selection Recommendations

The OVSA1ABLCR8 is the direct active equivalent for the obsolete OVSAABLCR8. Selection is based on the following engineering criteria:

Product Status: The OVSA1ABLCR8 carries active product status with current manufacturing support and inventory availability (2236 pcs in stock), whereas the OVSAABLCR8 is obsolete with limited remaining stock (760 pcs).

Compliance & Certifications: Both parts maintain identical RoHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental directives.

Electrical Compatibility: The forward voltage differential of 0.1V (2.6V to 2.5V) falls within standard LED circuit design tolerances and does not require circuit modification. Test current remains constant at 50mA.

Mechanical Compatibility: Identical package dimensions, lens specifications, and mounting type ensure direct PCB footprint compatibility. The 0.10mm height increase (3.45mm to 4.65mm) remains within standard surface mount assembly tolerances.

Performance Enhancement: The OVSA1ABLCR8 provides increased brightness output (5000mcd versus 1800mcd) while maintaining identical wavelength, viewing angle, and optical characteristics, resulting in improved visibility without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the OVSA1ABLCR8 be used as a direct replacement for the OVSAABLCR8 without PCB modification?

A: Yes. The OVSA1ABLCR8 maintains identical package dimensions, footprint, and mounting type. The 0.1V forward voltage reduction and 0.10mm height increase are within standard PCB assembly and circuit design tolerances and do not require layout changes.

Q: What is the significance of the millicandela rating increase from 1800mcd to 5000mcd?
