TE Connectivity 5-146261-8 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 5-146261-8 is an active-status rectangular connector header designed for through-hole mounting applications. This 16-position, 2-row connector operates within the AMPMODU Mod II series and provides board-to-board or cable interconnection with solder termination and push-pull fastening. The connector is constructed with liquid crystal polymer insulation and copper alloy contacts finished in gold for mating surfaces and tin for posts.

Substitute parts are identified to address inventory availability, packaging preferences, or specific application requirements while maintaining electrical and mechanical compatibility within the defined parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 5-146261-8 is determined by strict alignment with the following critical parameters:

Electrical Compatibility Requirements:

• 16 positions across 2 rows with 0.100" (2.54mm) pitch and row spacing
• Male pin contact type
• 3A current rating
• Gold-plated mating contacts and tin-plated posts
• Push-pull fastening mechanism

Mechanical Compatibility Requirements:

• Through-hole solder termination
• Unshrouded header configuration
• Board-to-board or cable connection style
• Breakaway connector type

Regulatory & Compliance Requirements:

• RoHS compliance status
• UL94 V-0 flammability rating
• EAR99 export classification

The Sullins Connector Solutions PBC08DAAN meets all critical electrical and mechanical parameters. Variations in insulation material (polybutylene terephthalate versus liquid crystal polymer), contact material (phosphor bronze versus copper alloy), contact finish thickness, and operating temperature range do not preclude substitution when application requirements fall within the overlapping specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The TE Connectivity 5-146261-8 and Sullins PBC08DAAN are electrically and mechanically interchangeable for applications requiring 16-position, 2-row, 0.100" pitch through-hole header connectors with 3A current capacity.

Regulatory Compliance:

Both parts meet UL94 V-0 flammability requirements and carry RoHS compliance certifications. The Sullins PBC08DAAN carries ROHS3 compliance, representing the most current regulatory standard. Both parts are classified as EAR99 for export purposes.

Physical Dimensional Considerations:

The Sullins PBC08DAAN exhibits slightly larger overall dimensions: post length is 0.030" longer, overall contact length is 0.040" longer, and insulation height is 0.010" taller. These dimensional differences must be evaluated against printed circuit board layout constraints and mating connector cavity depths. Applications with tight vertical clearance or specific PCB design requirements may necessitate the TE Connectivity part.

Material and Performance Differences:

The TE Connectivity part uses liquid crystal polymer insulation and copper alloy contacts, while the Sullins part uses polybutylene terephthalate insulation and phosphor bronze contacts. Both material combinations are suitable for the 3A current rating. The Sullins part supports an extended operating temperature range of -65°C to 125°C compared to the TE Connectivity range of -65°C to 105°C. Applications requiring operation above 105°C require the Sullins part.

The TE Connectivity part features thicker gold plating on mating contacts (30.0µin versus 10.0µin), which may provide enhanced corrosion resistance in high-humidity or corrosive environments.

Packaging and Availability:

The TE Connectivity part is supplied in tube packaging with 944 units in stock. The Sullins part is supplied in bulk packaging with 3972 units in stock. Packaging selection depends on assembly process requirements and inventory management practices.

Product Status:

Both parts maintain active product status with manufacturers, ensuring continued availability and technical support.

Frequently Asked Questions (FAQ)

Q: Can the Sullins PBC08DAAN directly replace the TE Connectivity 5-146261-8 in existing designs?

A: Direct replacement is possible for applications where the dimensional differences do not conflict with PCB layout or mating connector specifications. The Sullins part's longer post length (0.120" versus 0.090") and taller insulation height (0.100" versus 0.090") must be verified against PCB cavity depths and clearance requirements. Electrical performance is equivalent for all standard applications.

Q: What is the significance of the different contact materials?

A: The TE Connectivity part uses copper alloy contacts while the Sullins part uses phosphor bronze contacts. Both materials are suitable for the 3A current rating. Phosphor bronze offers slightly different mechanical properties and spring characteristics. For applications with high mating cycle requirements or specific contact force specifications, material selection should be verified against application requirements.

Q: Why does the TE Connectivity part have thicker gold plating?

A: The TE Connectivity 5-146261-8 features 30.0µin gold plating on mating contacts compared to 10.0µin on the Sullins part. Thicker gold plating provides enhanced protection against corrosion and oxidation in high-humidity, salt-spray, or chemically aggressive environments. Standard industrial applications typically function adequately with either plating thickness.

Q: Are there temperature-related limitations for substitution?

A: The Sullins PBC08DAAN supports operation to 125°C, while the TE Connectivity part is rated to 105°C. Applications requiring sustained operation above 105°C must use the Sullins part. Applications operating within -65°C to 105°C can use either part.

Q: What packaging differences exist between these parts?

A: The TE Connectivity part is supplied in tube packaging (944 units per order), while the Sullins part is supplied in bulk packaging (3972 units per order). Tube packaging is suitable for manual assembly or small-batch production. Bulk packaging is optimized for high-volume automated assembly processes. Selection depends on production volume and assembly methodology.

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity 5-146261-8 is RoHS Compliant. The Sullins PBC08DAAN is ROHS3 Compliant, representing the current regulatory standard. Both parts meet lead-free and hazardous substance restrictions for European Union and similar regulatory jurisdictions.

Q: What is the moisture sensitivity level for these connectors?

A: The TE Connectivity part carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The Sullins part is listed as Not Applicable for MSL, indicating no moisture sensitivity concerns. Both parts can be stored and handled without special moisture control measures.

Q: Can these connectors be used for board-to-board and cable applications interchangeably?

A: Yes. Both parts are specified for board-to-board or cable connection styles. The unshrouded header configuration and push-pull fastening mechanism support both application types. Mating connector selection should be based on the specific application requirements rather than the header part selection.

Q: What is the current rating for both parts?

A: Both the TE Connectivity 5-146261-8 and Sullins PBC08DAAN are rated for 3A continuous current per contact. Total system current capacity depends on the number of loaded positions and circuit design. For 16-position connectors with all positions loaded, maximum theoretical current is 48A (16 positions × 3A per position), subject to PCB trace and wire gauge limitations.
