Substitute Part Grouping Explanation

Substitution eligibility for the SSF-LXH101GD-01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

Forward voltage: 2.2V (primary group) or 2.1V (secondary group with voltage tolerance consideration)
Forward current: 20mA
Millicandela rating: 30mcd
Peak wavelength: 565nm (green)

Optical Parameters:

Lens type: Diffused, Tinted
Lens style: Round with Domed Top
Viewing angle: 60°

Mechanical Parameters:

Lens size: 5mm, T-1 3/4
Mounting type: Through Hole, Right Angle
Configuration: Single

Compliance Parameters:

RoHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)
REACH Unaffected

All substitute parts listed maintain these parameters. Parts with 2.1V forward voltage (SSF-LXH4RA5GD and SSF-LXH4RA5LGD) represent a minor voltage variation within acceptable tolerance for LED circuit board indicator applications and remain functionally equivalent.

Engineering Selection Recommendations

Primary Substitutes (2.2V Forward Voltage - Exact Match):

SSF-LXH100GD-01 is the recommended primary substitute. This part is active in production, maintains identical electrical and optical specifications to the SSF-LXH101GD-01, and carries the highest inventory level (63,216 units). All compliance certifications are equivalent: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 1.

SSF-LXH100GD and SSF-LXH104GD are secondary primary substitutes with active product status and substantial inventory availability (34,154 and 73,032 units respectively). Both maintain full parameter equivalence.

Secondary Substitutes (2.1V Forward Voltage - Minor Voltage Variation):

SSF-LXH4RA5GD and SSF-LXH4RA5LGD operate at 2.1V forward voltage, representing a 0.1V reduction from the original 2.2V specification. These parts maintain all other electrical, optical, and mechanical parameters. The voltage difference falls within typical LED tolerance ranges for circuit board indicator applications. Both parts carry active product status and ROHS3 compliance.

Compliance Verification:

All substitute parts maintain ROHS3 Compliant status, REACH Unaffected designation, and Moisture Sensitivity Level 1 (Unlimited). No additional compliance testing or verification is required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can SSF-LXH100GD-01 be used as a direct replacement for SSF-LXH101GD-01?

A: Yes. SSF-LXH100GD-01 is a direct substitute. Both parts share identical electrical specifications (2.2V, 20mA), optical characteristics (565nm peak wavelength, 30mcd, 60° viewing angle), mechanical configuration (5mm T-1 3/4 through-hole right-angle mount), and compliance certifications (ROHS3 Compliant, REACH Unaffected).

Q: What is the difference between the 2.2V and 2.1V forward voltage substitutes?

A: SSF-LXH4RA5GD and SSF-LXH4RA5LGD operate at 2.1V forward voltage compared to the original 2.2V specification. This 0.1V difference is within acceptable tolerance for LED circuit board indicator applications. All other parameters remain identical. Selection between 2.2V and 2.1V variants depends on circuit design requirements and available supply voltage headroom.

Q: Are there packaging differences between substitute parts?

A: The primary substitutes (SSF-LXH100GD, SSF-LXH100GD-01, SSF-LXH100LGD, SSF-LXH100LGD-01, SSF-LXH100MLGD, SSF-LXH104GD) are supplied in bulk packaging. SSF-LXH4RA5LGD has no specified packaging designation. These packaging variations do not affect component functionality or electrical performance.

Q: Why is SSF-LXH101GD-01 classified as obsolete?

A: The SSF-LXH101GD-01 is no longer in active production. Multiple active alternatives with identical specifications are available from Lumex Opto/Components Inc., ensuring continued design support and component availability.

Q: Can I use SSF-LXH100LGD or SSF-LXH100LGD-01 instead of SSF-LXH100GD-01?

A: Yes. SSF-LXH100LGD and SSF-LXH100LGD-01 are functionally equivalent substitutes with identical electrical and optical specifications. Selection among these variants may be based on inventory availability or packaging requirements.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts carry ROHS3 Compliant status, REACH Unaffected designation, and Moisture Sensitivity Level 1 (Unlimited). No additional compliance documentation or testing is required for direct substitution in applications previously using SSF-LXH101GD-01.

Q: Which substitute part has the highest inventory availability?

A: SSF-LXH104GD maintains the highest inventory level at 73,032 units. SSF-LXH100GD-01 is the second highest at 63,216 units. Both are suitable for high-volume production requirements.
