Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5-146276-5

The TE Connectivity 5-146276-5 is the direct active equivalent to the obsolete 5-146288-5. Both components share identical specifications across all critical parameters including pitch, position count, contact length, insulation height, operating temperature range, and current rating. The 5-146276-5 maintains the same AMPMODU Mod II series designation and differs only in termination style (standard solder versus kinked pin solder). This part carries active product status and maintains full RoHS compliance, making it the preferred replacement for direct substitution.

Secondary Recommendations by Application:

For Standard PCB Mounting (0.125" Post Length):

PEC05SFAN (Sullins): Tin-plated mating contact, phosphor bronze construction, 3A rating, -65°C to 125°C operating range
78511-405HLF (Amphenol ICC): Tin-plated mating contact, phosphor bronze construction, 5A rating, -65°C to 125°C operating range

For Extended Post Length Applications:

PBC05SFBN (0.220" post): Gold-plated mating contact, phosphor bronze construction
PBC05SFCN (0.320" post): Gold-plated mating contact, phosphor bronze construction
PBC05SFDN (0.420" post): Gold-plated mating contact, phosphor bronze construction
PBC05SFEN (0.520" post): Gold-plated mating contact, phosphor bronze construction
PEC05SFBN (0.220" post): Tin-plated mating contact, phosphor bronze construction
PEC05SFCN (0.320" post): Tin-plated mating contact, phosphor bronze construction

Compliance Considerations:

All substitute parts maintain UL94 V-0 flammability rating and RoHS compliance status. Sullins components carry ROHS3 compliance with REACH Unaffected status. TE Connectivity 5-146276-5 maintains RoHS compliance with Vendor Undefined REACH status. Amphenol ICC 78511-405HLF carries REACH Affected designation.

Material Compatibility:

The original 5-146288-5 uses Liquid Crystal Polymer (LCP) insulation material. All active substitutes employ either LCP (5-146276-5) or Polybutylene Terephthalate (PBT) insulation. Both materials meet UL94 V-0 flammability requirements and are suitable for through-hole soldering applications.

Contact Finish Selection:

Gold-plated mating contacts (5-146288-5, 5-146276-5, PBC series) provide superior corrosion resistance and are recommended for applications requiring extended shelf life or exposure to corrosive environments. Tin-plated mating contacts (78511-405HLF, PEC series) are suitable for standard industrial applications and offer cost efficiency.

Frequently Asked Questions (FAQ)

Q: Can I use PBC05SFBN as a direct replacement for 5-146288-5?

A: PBC05SFBN is functionally compatible with 5-146288-5 for the core connector interface (5-position, 2.54mm pitch, male pins, through-hole mounting). However, the contact post length differs: PBC05SFBN has 0.220" (5.58mm) posts versus 0.125" (3.18mm) on the original part. This difference affects PCB mounting depth. Use PBC05SFBN only if your PCB design accommodates the longer post length. For identical post length, use PEC05SFAN or 5-146276-5.

Q: What is the difference between PBC05SFAN and PEC05SFAN?

A: Both parts share identical mechanical and electrical specifications with 0.120" (3.05mm) contact post length. The primary difference is contact finish: PBC05SFAN features gold-plated mating contacts while PEC05SFAN features tin-plated mating contacts. Select PBC05SFAN for applications requiring enhanced corrosion resistance; select PEC05SFAN for standard industrial applications.

Q: Is the 78511-405HLF from Amphenol ICC compatible with my design using 5-146288-5?

A: Yes, the 78511-405HLF is mechanically and electrically compatible. It maintains the 5-position, 2.54mm pitch header configuration with 0.120" (3.05mm) contact post length. The 78511-405HLF offers a higher current rating (5A versus 3A) and extended operating temperature range (-65°C to 125°C versus -65°C to 105°C). Contact finish differs (tin versus gold), and the insulation material is not specified in available documentation.

Q: Why do the Sullins PBC and PEC series have different post lengths?

A: The Sullins product line offers multiple post length options to accommodate various PCB thicknesses and mounting depths. The suffix letter indicates post length: A=0.120", B=0.220", C=0.320", D=0.420", E=0.520". Select the post length matching your PCB thickness and mounting requirements. All variants maintain the same 5-position, 2.54mm pitch configuration.

Q: Can I substitute a part with a higher current rating (5A) for my 3A application?

A: Yes. The 78511-405HLF (5A rating) is suitable for applications designed for 3A operation. Higher current rating provides additional safety margin and does not negatively impact performance in lower-current applications. All other electrical and mechanical parameters remain compatible.

Q: What is the significance of the operating temperature range difference (-65°C to 105°C versus -65°C to 125°C)?

A: The original 5-146288-5 operates to 105°C maximum, while most active substitutes operate to 125°C. For applications operating within the 105°C limit, either specification is acceptable. For applications requiring operation above 105°C, select substitutes with -65°C to 125°C rating (all Sullins parts and 78511-405HLF).

Q: Are there any packaging differences between the main part and substitutes?

A: The original 5-146288-5 packaging is not specified in available documentation. The TE Connectivity 5-146276-5 is supplied in bulk packaging. All Sullins substitutes (PBC and PEC series) and the Amphenol ICC 78511-405HLF are supplied in bulk packaging. Confirm packaging requirements with your procurement department.

Q: What does "Breakaway" connector type mean?

A: Breakaway connectors feature individual pins that can be separated from the main header assembly. This allows for custom pin configurations or removal of unused pins. The 5-146288-5 and most substitutes support this feature, enabling flexible assembly configurations.

Q: Is RoHS compliance maintained across all substitutes?

A: Yes. The original 5-146288-5 is RoHS Compliant. The TE Connectivity 5-146276-5 maintains RoHS Compliance. All Sullins substitutes carry ROHS3 Compliance. The Amphenol ICC 78511-405HLF is RoHS Compliant. All parts meet RoHS requirements for new designs.

Q: Can I mix contact finishes (gold and tin) in the same assembly?

A: Contact finish selection should be consistent within a mating pair to ensure optimal electrical performance and contact reliability. Mixing gold-plated and tin-plated contacts in the same connector interface is not recommended. Select either all gold-plated (5-146288-5, 5-146276-5, PBC series) or all tin-plated (78511-405HLF, PEC series) for a given application.
