Substitute Part Grouping Explanation

The 4303F5 manufactured by Visual Communications Company (VCC) qualifies as a direct substitute for the SLH-34MG3FS based on the following alignment criteria:

Matching Parameters:

• Green LED color specification
• Diffused lens transparency
• T-1 form factor and through-hole mounting type
• ROHS3 compliance certification
• MSL 1 rating (unlimited moisture sensitivity)
• REACH unaffected status
• EAR99 export classification
• Identical HTSUS commodity code (8541.41.0000)

The 4303F5 maintains active product status with established supply chain availability, providing a viable replacement path for the obsolete SLH-34MG3FS in applications requiring green LED indication with diffused optical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 4303F5 from Visual Communications Company represents the qualified substitute for the obsolete SLH-34MG3FS. Selection of this alternative is supported by:

Compliance Alignment: Both components maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory continuity in applications previously designed with the SLH-34MG3FS.

Environmental Ratings: Matching MSL 1 ratings confirm equivalent moisture sensitivity performance across standard industrial and commercial operating environments.

Form Factor Compatibility: Identical T-1 through-hole radial package configuration ensures mechanical and electrical compatibility with existing PCB layouts and circuit designs without requiring board redesign.

Supply Chain Status: The 4303F5 maintains active product status with documented inventory availability, providing long-term procurement stability compared to the obsolete SLH-34MG3FS.

Frequently Asked Questions (FAQ)

Q: Can the 4303F5 be used as a direct replacement for the SLH-34MG3FS without circuit modification?

A: Yes. Both components share identical T-1 through-hole radial package configuration, green color specification, and diffused lens characteristics. No circuit modification is required for mechanical or electrical compatibility at the component level.

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

A: No. Both components maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. MSL ratings are identical at level 1 (unlimited moisture sensitivity).

Q: What electrical parameters should be verified when substituting the 4303F5 for the SLH-34MG3FS?

A: The 4303F5 specifies 2.1V forward voltage at 10mA test current with 25mcd brightness and 55° viewing angle. These parameters should be confirmed against the original circuit design requirements, as the SLH-34MG3FS electrical specifications were not provided in available documentation.

Q: Is the 4303F5 available in the same packaging format?

A: Yes. The 4303F5 is supplied in radial through-hole T-1 package configuration, matching the SLH-34MG3FS form factor. Standard bulk packaging is available.

Q: Why is the SLH-34MG3FS listed as obsolete?

A: The SLH-34MG3FS has been discontinued by Rohm Semiconductor. The 4303F5 provides functional equivalence for applications requiring green diffused LED indication in T-1 through-hole format.
