Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5-146280-5

The TE Connectivity 5-146280-5 is the manufacturer-recommended direct replacement for the obsolete 104345-3. This part maintains identical electrical and mechanical specifications including pitch, position count, contact length dimensions, and current rating. The 5-146280-5 is classified as active with RoHS compliance, addressing regulatory requirements for new designs. The insulation material differs (Liquid Crystal Polymer versus Thermoplastic), providing enhanced thermal and chemical resistance. Contact finish on the post changes from Tin-Lead to Tin, eliminating lead content. This part is available in bulk packaging with 9060 units in stock.

Secondary Recommendation: Sullins Connector Solutions PBC05SAAN

The Sullins PBC05SAAN provides an alternative from an established connector manufacturer with active product status and ROHS3 compliance. This part matches the core electrical parameters and maintains the 0.100" pitch and 5-position configuration. The contact material is Phosphor Bronze rather than Copper Alloy, and the insulation material is Polybutylene Terephthalate (PBT). Operating temperature range extends to 125°C, providing additional thermal margin. The overall contact length is 0.450" (11.43mm) compared to 0.440" (11.18mm) for the original part, representing a minor dimensional variation. This part is available in bulk packaging with 2200 units in stock.

Extended Post Length Alternatives: Sullins PBC05SABN through PBC05SAHN

The Sullins series PBC05SABN, PBC05SACN, PBC05SADN, PBC05SAEN, PBC05SAFN, PBC05SAGN, and PBC05SAHN provide variants with progressively longer contact post lengths (0.230" through 0.820"), accommodating applications requiring deeper PCB penetration or extended solder joint engagement. All variants maintain identical mating contact length (0.230"), pitch (0.100"), position count (5), and current rating (3A). These parts are suitable for designs where the original 0.120" post length is insufficient. All variants are ROHS3 compliant and active products.

Alternative Manufacturer: 3M 2305-6111-TG

The 3M 2305-6111-TG represents an alternative from a major connector supplier. This part maintains core compatibility with 0.100" pitch, 5 positions, and 3A current rating. The operating temperature range is -55°C to 105°C, which is narrower at the low end compared to the original -65°C specification. The insulation material is Thermoplastic with glass filling, and the contact finish thickness on the mating surface is 10.0µin compared to 15.0µin for the original part. This part is RoHS non-compliant and available with 609 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-146280-5 be used as a direct drop-in replacement for the 104345-3?

A: The 5-146280-5 is electrically and mechanically compatible with the 104345-3 for applications within the specified operating parameters. Both parts maintain identical pitch (0.100"), position count (5), contact length dimensions, and current rating (3A). The primary differences are insulation material (LCP versus Thermoplastic) and contact finish on the post (Tin versus Tin-Lead). These differences do not affect functional compatibility in standard applications.

Q: What is the significance of the different contact post lengths in the Sullins PBC05SA series?

A: The contact post length determines how far the pin extends into the PCB or mating connector. The original 104345-3 has a 0.120" post length. Sullins offers variants from 0.230" to 0.820" to accommodate different PCB thicknesses and solder joint requirements. Selection depends on the specific application's PCB thickness and mechanical engagement needs. All variants maintain identical mating contact length and electrical performance.

Q: Are there compliance differences between the substitute parts?

A: Yes. The original 104345-3 is RoHS non-compliant. The TE Connectivity 5-146280-5 is RoHS Compliant. All Sullins variants (PBC05SAAN through PBC05SAHN) are ROHS3 Compliant. The 3M 2305-6111-TG is RoHS non-compliant. For new designs subject to RoHS requirements, the 5-146280-5 or Sullins variants are appropriate selections.

Q: What is the difference between Copper Alloy and Phosphor Bronze contact materials?

A: Both materials are acceptable for this connector category and maintain the specified electrical performance. Copper Alloy is used in the original 104345-3 and TE Connectivity 5-146280-5. Phosphor Bronze is used in all Sullins variants. Phosphor Bronze offers enhanced spring characteristics and wear resistance, which can improve contact reliability over extended mating cycles. The choice between materials does not affect electrical compatibility.

Q: Can I use a part with a narrower operating temperature range?

A: The 3M 2305-6111-TG has an operating range of -55°C to 105°C compared to the original -65°C to 105°C. This part is suitable only for applications that do not require operation below -55°C. For applications requiring the full -65°C lower limit, use the 5-146280-5 or Sullins variants, which all support -65°C operation.

Q: What packaging options are available?

A: The TE Connectivity 5-146280-5 is available in Bulk packaging. The Sullins variants are available in Bulk packaging. The 3M 2305-6111-TG packaging type is not specified in the available data. Bulk packaging is standard for high-volume applications and is suitable for automated assembly processes.

Q: Are there inventory considerations for part selection?

A: Current inventory levels are: 5-146280-5 (9060 units), PBC05SAAN (2200 units), PBC05SABN (712 units), PBC05SACN (695 units), PBC05SADN (809 units), PBC05SAEN (1007 units), PBC05SAFN (693 units), PBC05SAGN (1100 units), PBC05SAHN (1015 units), and 2305-6111-TG (609 units). The 5-146280-5 has the highest inventory availability. For applications with extended lead times or high-volume requirements, inventory levels should be confirmed with the supplier.

Q: What is the difference between the original termination specification and the substitutes?

A: The original 104345-3 specifies "Kinked Pin, Solder" termination. The 5-146280-5 specifies "Solder" termination without the kinked pin designation. The Sullins and 3M variants specify "Solder" termination. All parts are suitable for standard solder reflow processes. The kinked pin feature in the original part provides additional mechanical retention during soldering; however, standard solder termination is functionally equivalent for most applications.
