Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5-146278-6

The 5-146278-6 represents the direct active equivalent from the original manufacturer. This part maintains identical electrical and mechanical specifications to the 104346-4 while offering ROHS3 compliance status. The part is actively produced and maintains full compatibility with the original design parameters. This selection is appropriate for applications requiring manufacturer continuity and regulatory compliance.

Secondary Recommendation: Sullins Connector Solutions PBC06 Series

The Sullins PBC06 series (PBC06SAAN, PBC06SABN, PBC06SACN, PBC06SADN, PBC06SAEN, PBC06SAFN, PBC06SAGN) provides functionally equivalent alternatives with enhanced operating temperature ranges (-65°C ~ 125°C) and ROHS3 compliance. These parts differ primarily in contact post length, accommodating various PCB thickness and mounting depth requirements. Selection within this series depends on specific application mounting depth specifications. All variants maintain the core 6-position, 2.54mm pitch, 3A current rating, and UL94 V-0 flammability rating.

Alternative Recommendation: Amphenol ICC 77311-103-06LF

The 77311-103-06LF from the BERGSTIK series offers RoHS compliance and extended operating temperature range (-65°C ~ 125°C). This part features gold-plated mating contacts and is suitable for applications requiring enhanced contact reliability. The part is actively produced and maintains full electrical compatibility.

Alternative Recommendation: 3M 2306-6111-TG

The 2306-6111-TG from the 3M 2300 series provides functional equivalence with gold-plated mating contacts. This part operates within the specified temperature range and maintains UL94 V-0 flammability rating. Note that this part is RoHS non-compliant, limiting its application in regulated environments.

Compliance Considerations:

For applications requiring RoHS compliance, select from the following active parts: 5-146278-6 (ROHS3), PBC06SAAN through PBC06SAGN (ROHS3), or 77311-103-06LF (RoHS Compliant). The original 104346-4 is RoHS non-compliant and should be replaced in new designs targeting regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the 104346-4 be directly replaced with the 5-146278-6?

A: Yes. The 5-146278-6 maintains identical electrical and mechanical specifications including 6-position configuration, 0.100" (2.54mm) pitch, 3A current rating, and -65°C ~ 105°C operating temperature range. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant).

Q: What is the difference between the various Sullins PBC06 variants?

A: The PBC06 series variants differ exclusively in contact post length. PBC06SAAN features 0.120" (3.05mm) post length, PBC06SABN features 0.230" (5.84mm), PBC06SACN features 0.320" (8.13mm), PBC06SADN features 0.420" (10.67mm), PBC06SAEN features 0.520" (13.21mm), PBC06SAFN features 0.620" (15.75mm), and PBC06SAGN features 0.720" (18.29mm). Selection depends on PCB thickness and mounting depth requirements. All variants maintain identical electrical specifications and 6-position, 2.54mm pitch configuration.

Q: Are all substitute parts rated for the same current and voltage?

A: All substitute parts maintain the 3A current rating. The original 104346-4 specifies 30VAC voltage rating. Substitute parts do not specify voltage rating in their documentation, indicating they are suitable for standard logic-level applications. For applications requiring specific voltage ratings above standard logic levels, consult detailed product specifications.

Q: Which substitute part offers the best temperature performance?

A: The Sullins PBC06 series and Amphenol ICC 77311-103-06LF offer extended operating temperature range of -65°C ~ 125°C, compared to the original -65°C ~ 105°C specification. The 3M 2306-6111-TG operates to -55°C minimum, which is less stringent than the original specification. For applications requiring maximum temperature margin, select from the Sullins or Amphenol options.

Q: What are the RoHS compliance implications for part selection?

A: The original 104346-4 is RoHS non-compliant. For new designs or applications in regulated markets requiring RoHS compliance, select from: 5-146278-6 (ROHS3 Compliant), PBC06SAAN through PBC06SAGN (ROHS3 Compliant), or 77311-103-06LF (RoHS Compliant). The 3M 2306-6111-TG and Amphenol 77311-103-06LF are REACH Affected; the Sullins variants are REACH Unaffected.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, provided the application accommodates the contact post length variation. The primary design consideration is PCB mounting hole depth. The original 104346-4 features 0.120" (3.05mm) post length. Substitute parts with longer post lengths (PBC06SABN through PBC06SAGN) require deeper PCB holes or surface-mount accommodation. Substitute parts with equivalent or shorter post lengths (5-146278-6, 2306-6111-TG, 77311-103-06LF, PBC06SAAN) are directly interchangeable in existing through-hole designs.

Q: What packaging options are available?

A: The 5-146278-6 is supplied in Bulk packaging. The 2306-6111-TG is supplied in Bulk packaging. The 77311-103-06LF is supplied in Bag packaging. The Sullins PBC06 series is supplied in Bulk packaging. Packaging selection does not affect electrical or mechanical compatibility; it addresses procurement and inventory management requirements.

Q: Are there any contact finish differences between substitute parts?

A: Yes. The original 104346-4 features Tin-Lead contact finish on both mating and post surfaces. The 5-146278-6 features Tin finish. The 2306-6111-TG features Gold mating contact with Tin-Lead post finish. The 77311-103-06LF features Gold or Gold GXT mating contact with Tin post finish. The Sullins PBC06 series features Gold mating contact with Tin post finish. Contact finish variations do not affect electrical compatibility but may influence corrosion resistance and contact reliability in specific environmental conditions.
