Engineering Selection Recommendations

The QBHP686-IGH is the qualified substitute for the obsolete QBHP686-IGN-2913. Selection of this alternative is based on the following engineering criteria:

Product Status Transition: The QBHP686-IGN-2913 is classified as obsolete, creating supply discontinuity risk. The QBHP686-IGH maintains active product status with QT Brightek, ensuring long-term availability and manufacturing support.

Compliance Alignment: Both parts maintain ROHS3 compliance and identical export classification (EAR99), ensuring regulatory compatibility across applications and markets.

Electrical Compatibility: The forward voltage differential of 0.1V (3V versus 2.9V) and current test variation (100mA versus 150mA) fall within standard circuit design tolerance for green LED indication applications. Both parts operate within the same wavelength specification (525nm dominant), ensuring color consistency in visual indication systems.

Mechanical and Optical Equivalence: Identical package format (1113/2835 metric), physical dimensions (3.10mm x 2.80mm x 1.00mm maximum height), lens configuration (rectangle with flat top, clear colorless), and viewing angle (120°) ensure direct mechanical and optical interchangeability on PCB assemblies.

Packaging Consideration: The QBHP686-IGH is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount production. This packaging format is compatible with automated pick-and-place assembly equipment.

Moisture Sensitivity: The MSL rating change from 2A (4 Weeks) to 3 (168 Hours) requires standard handling procedures during storage and assembly. This represents a standard variation within the QBHP686 series and does not impact functional performance.

Frequently Asked Questions (FAQ)

Q: Can the QBHP686-IGH be used as a direct replacement for the QBHP686-IGN-2913 on existing PCB designs?

A: Yes. The QBHP686-IGH is mechanically and optically equivalent. Identical package format, physical dimensions, lens configuration, and viewing angle enable direct PCB footprint compatibility. Electrical parameters (forward voltage and test current) are within standard design tolerance for green LED indication circuits.

Q: What is the significance of the forward voltage difference between the two parts?

A: The QBHP686-IGN-2913 specifies 3V typical forward voltage, while the QBHP686-IGH specifies 2.9V typical. This 0.1V difference is within normal manufacturing tolerance for LED components and does not require circuit redesign for standard indication applications. Circuit designs with voltage regulation or current-limiting resistors will accommodate this variation without functional impact.

Q: Why does the QBHP686-IGH have a higher test current specification?

A: The QBHP686-IGH specifies 150mA test current compared to 100mA for the QBHP686-IGN-2913. This represents the measurement condition used during component characterization and does not indicate higher operating current requirement. Actual circuit operating current is determined by application-specific design parameters, not by test current specification.

Q: What is the difference between standard packaging and Tape & Reel (TR) format?

A: The QBHP686-IGN-2913 uses standard packaging, while the QBHP686-IGH is supplied in Tape & Reel (TR) format. Tape & Reel is the industry standard for surface mount component delivery to automated assembly lines. Both formats contain identical components; the difference is in delivery and handling method. TR format is compatible with standard pick-and-place equipment used in modern PCB assembly.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance status and EAR99 export classification. Regulatory requirements for use in end applications are equivalent.

Q: What is the Moisture Sensitivity Level (MSL) difference, and does it affect component selection?

A: The QBHP686-IGN-2913 has MSL 2A (4 Weeks), while the QBHP686-IGH has MSL 3 (168 Hours). MSL rating indicates the maximum time a component can be stored in ambient conditions before requiring baking to remove absorbed moisture. MSL 3 (168 Hours) is standard for surface mount LEDs and is compatible with typical manufacturing environments. This difference does not affect functional performance and is managed through standard component handling procedures.

Q: Why is the QBHP686-IGN-2913 classified as obsolete?

A: Product obsolescence is determined by manufacturer production decisions and market demand. The QBHP686-IGH represents the active continuation of the QBHP686 series and is the recommended alternative for new designs and ongoing production requirements.

Q: Can inventory of QBHP686-IGN-2913 be mixed with QBHP686-IGH in production?

A: Yes. Both parts are mechanically, optically, and electrically equivalent within standard design tolerance. Mixed inventory can be used interchangeably in assembly operations without functional impact or performance degradation.
