Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5-146278-5

The TE Connectivity 5-146278-5 is the recommended primary substitute for the obsolete 104346-3. This part maintains identical core specifications including pitch, position count, contact mating length, and current rating. The 5-146278-5 is classified as Active product status, ensuring long-term availability and supply chain continuity. The part achieves RoHS Compliance, providing regulatory advantage over the non-compliant original part. Contact post length and overall contact length are identical to the main part, ensuring direct mechanical compatibility with existing PCB designs. The transition from Tin-Lead to Tin contact finish on the mating surface represents a minor material change that does not affect electrical performance within the specified operating parameters.

Secondary Substitutes: Sullins Connector Solutions PBC05 Series

The Sullins Connector Solutions PBC05 series (PBC05SAAN, PBC05SABN, PBC05SAFN, PBC05SAGN, and related variants) provides alternative substitution options with enhanced compliance characteristics. All PBC05 variants are classified as Active product status and achieve ROHS3 Compliance. These parts maintain the critical electrical interface parameters: 0.100" (2.54mm) pitch, 5 positions, 1 row, male pin contacts, and 3A current rating.

The PBC05 series differs from the main part in contact post length, which varies across the product family to accommodate different PCB stack-up depths. Selection within the PBC05 series depends on specific application requirements:

PBC05SAAN: Contact post length 0.120" (3.05mm) — direct mechanical equivalent to 104346-3
PBC05SABN: Contact post length 0.230" (5.84mm) — extended post for deeper PCB penetration
PBC05SAFN: Contact post length 0.620" (15.75mm) — long post for high stack-up applications
PBC05SAGN: Contact post length 0.720" (18.29mm) — extended long post for maximum stack-up

All PBC05 variants feature Phosphor Bronze contact material, Gold mating surface finish, and Polybutylene Terephthalate (PBT) insulation material. Operating temperature range extends to -65°C ~ 125°C, providing superior thermal performance compared to the original part. Moisture Sensitivity Level is Not Applicable, indicating superior environmental stability.

Alternative Substitute: 3M 2305-6111-TG

The 3M 2305-6111-TG represents an alternative from a different manufacturer within the 2300 series. This part maintains core electrical specifications and is classified as Active product status. However, the 2305-6111-TG is RoHS non-compliant, matching the regulatory status of the original part. Operating temperature range is -55°C ~ 105°C, which is narrower than the original specification at the lower temperature limit. Insulation height is 0.100" (2.54mm) compared to 0.090" (2.54mm) on the original part. This part is suitable for applications where regulatory compliance is not a requirement and where the narrower temperature range is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-146278-5 be used as a direct replacement for the 104346-3 in existing designs?

A: Yes. The 5-146278-5 maintains identical pitch spacing (0.100"/2.54mm), position count (5), contact mating length (0.230"/5.84mm), contact post length (0.120"/3.05mm), and overall contact length (0.440"/11.18mm). The primary difference is the contact finish material on the mating surface, which transitions from Tin-Lead to Tin. This change does not affect electrical performance within the specified operating parameters. PCB footprints and mating connector designs require no modification.

Q: What is the difference between the various Sullins PBC05 variants?

A: All Sullins PBC05 variants share identical electrical specifications and core mechanical dimensions. The distinguishing parameter is contact post length, which varies to accommodate different PCB stack-up requirements. Selection depends on the depth of PCB penetration required by the application. PBC05SAAN provides the shortest post (0.120"/3.05mm) for standard applications, while PBC05SAGN provides the longest post (0.720"/18.29mm) for high stack-up configurations.

Q: Are there compliance differences between the substitute parts?

A: Yes. The TE Connectivity 5-146278-5 achieves RoHS Compliance. The Sullins PBC05 series achieves ROHS3 Compliance. The 3M 2305-6111-TG is RoHS non-compliant, matching the original part. The original 104346-3 is RoHS non-compliant. For applications requiring RoHS compliance, the 5-146278-5 or any PBC05 variant is required.

Q: What is the operating temperature range for each substitute?

A: The TE Connectivity 5-146278-5 operates from -65°C to 105°C, matching the original part. The Sullins PBC05 series extends the upper limit to 125°C, providing -65°C to 125°C operation. The 3M 2305-6111-TG operates from -55°C to 105°C, with a narrower lower temperature limit. Application requirements determine which temperature range is appropriate.

Q: Does contact finish material affect electrical performance?

A: Contact finish material affects corrosion resistance and long-term reliability in specific environmental conditions. The original part uses Tin-Lead finish on the mating surface. The TE Connectivity 5-146278-5 uses Tin finish. The Sullins PBC05 series uses Gold finish. All three finishes are suitable for standard electronic applications. Gold finish provides superior corrosion resistance in harsh environments. Tin finish provides adequate performance in controlled environments. Selection depends on application environment and reliability requirements.

Q: Can the 3M 2305-6111-TG be used interchangeably with the TE Connectivity parts?

A: The 3M 2305-6111-TG maintains the critical electrical interface parameters and is mechanically compatible. However, the insulation height is 0.100" (2.54mm) compared to 0.090" (2.29mm) on the original part, and the operating temperature range is narrower at the lower limit (-55°C vs. -65°C). These differences may affect compatibility in specific applications. Verification of mechanical clearance and temperature requirements is necessary before substitution.

Q: What inventory levels are available for each substitute?

A: Current inventory levels are: TE Connectivity 5-146278-5 (815 pcs), 3M 2305-6111-TG (609 pcs), Sullins PBC05SAAN (2200 pcs), Sullins PBC05SABN (712 pcs), Sullins PBC05SAFN (693 pcs), and Sullins PBC05SAGN (1100 pcs). The Sullins PBC05SAAN variant offers the highest inventory availability.

Q: Are there any packaging differences between the substitute parts?

A: The TE Connectivity 5-146278-5 is supplied in Bulk packaging. The Sullins PBC05 series is supplied in Bulk packaging. The 3M 2305-6111-TG packaging specification is not provided. Bulk packaging is standard for these connector types and does not affect component functionality or compatibility.
