Engineering Selection Recommendations

Primary Substitute: NTE3004

The NTE3004 is the qualified substitute for the obsolete SSL-LXA227ID. Selection rationale is based on the following engineering criteria:

Product Status: The NTE3004 maintains active product status with confirmed inventory availability (1255 pcs), ensuring long-term procurement continuity compared to the obsolete SSL-LXA227ID.

Mechanical Compatibility: Both components share identical mounting specifications—through-hole axial configuration with flat leads, 1.80mm lens diameter, round domed-top lens style, and 2.72mm maximum height. Direct PCB footprint compatibility is confirmed.

Electrical Performance: The NTE3004 operates at 1.9V forward voltage compared to the SSL-LXA227ID's 2.1V specification. This 0.2V difference is within acceptable tolerance for red LED indication circuits and does not require circuit redesign. Both components operate at identical 20mA test current and 60° viewing angle.

Brightness Consideration: The NTE3004 provides 45mcd brightness versus the SSL-LXA227ID's 8mcd rating. The increased brightness is compatible with indication applications and does not create functional incompatibility.

Wavelength Specification: The NTE3004 peak wavelength is 660nm compared to the SSL-LXA227ID's 635nm. Both wavelengths fall within the red spectrum and are visually indistinguishable in indication applications.

Regulatory Compliance: Both components are ROHS3 compliant and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the NTE3004 be used as a direct replacement for the SSL-LXA227ID without circuit modification?

A: Yes. The NTE3004 is mechanically and electrically compatible with the SSL-LXA227ID. The 0.2V forward voltage difference (1.9V vs 2.1V) does not require circuit redesign for indication applications. PCB footprint compatibility is confirmed through identical axial mounting specifications and lead geometry.

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

A: The NTE3004 provides 45mcd brightness compared to the SSL-LXA227ID's 8mcd. This increased brightness is a performance enhancement for indication circuits and does not create incompatibility. The higher brightness may improve visibility in high-ambient-light environments.

Q: Are there wavelength differences between these components?

A: The NTE3004 has a peak wavelength of 660nm versus the SSL-LXA227ID's 635nm. Both wavelengths are within the red spectrum and produce visually equivalent red indication. The wavelength difference is not perceptible in typical indication applications.

Q: What packaging format is the NTE3004 supplied in?

A: The NTE3004 is supplied in bag packaging, compared to the SSL-LXA227ID's unspecified packaging format. Both components maintain identical component dimensions and through-hole axial configuration for PCB assembly.

Q: Are both components RoHS compliant?

A: Yes. Both the SSL-LXA227ID and NTE3004 are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and assembly.

Q: What is the viewing angle specification for both components?

A: Both components specify a 60° viewing angle, ensuring identical light distribution characteristics in indication circuit applications.
