Key Parameters

Substitute Part Grouping Explanation

Substitution of the OVSAABC2R8 is determined by the following critical parameters:

Color and Wavelength Compatibility: The substitute must emit amber light at 591nm dominant wavelength to maintain visual indication consistency.

Electrical Characteristics: Forward voltage (Vf) and test current must be compatible with existing circuit designs. The substitute OVSA1ABC2R8 operates at 2.4V, which is within acceptable tolerance for amber LED applications.

Optical Performance: Millicandela rating, viewing angle, and lens characteristics must support the intended indication function. The substitute provides enhanced brightness (1500mcd vs. 700mcd).

Package and Mounting: Surface mount configuration and footprint compatibility are essential. The OVSA1ABC2R8 uses 4-SMD J-Lead packaging, which maintains mechanical compatibility with 4-PLCC footprints.

Regulatory Compliance: Both components maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 5A).

Parameter Comparison

Engineering Selection Recommendations

The OVSA1ABC2R8 is the designated substitute for the obsolete OVSAABC2R8. Selection of this substitute is based on the following engineering criteria:

Product Status: The OVSAABC2R8 is obsolete and no longer manufactured. The OVSA1ABC2R8 maintains active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: Both components maintain identical ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production.

Functional Compatibility: Both components share identical color, wavelength, viewing angle, and mounting characteristics. The forward voltage differential (2.6V to 2.4V) is within acceptable operating margins for amber LED indication circuits.

Optical Enhancement: The substitute provides doubled brightness (1500mcd vs. 700mcd), which improves visibility without requiring circuit redesign.

Packaging Considerations: The transition from 4-PLCC to 4-SMD J-Lead packaging requires PCB footprint verification. Dimensional compatibility (3.20mm L x 2.70mm W vs. 3.20mm L x 2.80mm W) is maintained within manufacturing tolerances.

Frequently Asked Questions (FAQ)

Q: Can the OVSA1ABC2R8 directly replace the OVSAABC2R8 without circuit modification?

A: The OVSA1ABC2R8 operates at 2.4V forward voltage compared to the original 2.6V. This 0.2V reduction is compatible with standard amber LED circuit designs. Verify that your current-limiting resistor accommodates the lower forward voltage. No other circuit modifications are required.

Q: What is the difference between 4-PLCC and 4-SMD J-Lead packaging?

A: Both are surface mount packages with identical footprint dimensions (3.20mm length). The 4-PLCC uses a plastic leaded chip carrier, while the 4-SMD J-Lead uses surface mount leads. PCB footprints must be verified for compatibility before assembly.

Q: Does the increased brightness of the OVSA1ABC2R8 (1500mcd vs. 700mcd) affect circuit operation?

A: Brightness is determined by forward current, which is controlled by the circuit's current-limiting resistor. The substitute's higher brightness rating indicates improved light output capability at the same 50mA test current. Existing circuits will operate identically; the substitute simply provides enhanced visibility.

Q: Are there any compliance differences between the two parts?

A: Both components are ROHS3 compliant, REACH unaffected, and share identical moisture sensitivity levels (MSL 5A). No compliance issues arise from substitution.

Q: What inventory considerations apply to this substitution?

A: The OVSAABC2R8 is obsolete with limited remaining stock (699 pcs). The OVSA1ABC2R8 is in active production with substantial inventory availability (5364 pcs), ensuring reliable supply for ongoing production and future orders.
