Part Overview

The TE Connectivity 5-146268-8 is a vertical rectangular connector header with 16 positions at 2.54mm pitch, designed for through-hole board-to-board or cable applications. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. The AMPMODU Mod II series connector features male pins with kinked solder termination and push-pull fastening, suitable for applications requiring 3A current capacity across an operating temperature range of -65°C to 105°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 5-146268-8 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector type (Header, Breakaway)
• Contact type (Male Pin)
• Pitch - mating (0.100" / 2.54mm)
• Number of positions (16)
• Number of rows (2)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Current rating (3A)
• Material flammability rating (UL94 V-0)
• RoHS compliance status

Secondary Compatibility Parameters:

• Operating temperature range
• Contact finish specifications
• Insulation material properties
• Contact material composition

The substitute parts identified maintain compatibility across all primary criteria. Variations in secondary parameters are noted where they occur and do not preclude functional substitution within the specified electrical and mechanical constraints.

Engineering Selection Recommendations

TE Connectivity 5-146256-8 (MFR Recommended Substitute)

The 5-146256-8 is the primary recommended substitute for the obsolete 5-146268-8. Both components are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical electrical and mechanical specifications across all critical parameters. The 5-146256-8 carries active product status with significantly higher inventory availability (5563 units in stock versus 1150 units for the main part). The primary distinction is termination style: the 5-146256-8 features standard solder termination, whereas the 5-146268-8 specifies kinked pin solder termination. Both configurations are compatible with standard through-hole PCB assembly processes. ROHS3 compliance and UL94 V-0 flammability rating are maintained. This substitute is suitable for direct replacement in new designs and legacy system support.

Sullins Connector Solutions PBC08DAAN (Similar Substitute)

The PBC08DAAN provides an alternative from a different manufacturer with active product status and robust inventory (3972 units in stock). This connector maintains compatibility across all primary substitution criteria, including 16-position, 2-54mm pitch configuration, male pin contacts, through-hole mounting, 3A current rating, and UL94 V-0 flammability compliance. Secondary parameter variations include contact material (Phosphor Bronze versus Copper Alloy), insulation material (PBT versus LCP), and extended operating temperature range (-65°C to 125°C versus -65°C to 105°C). Contact finish thickness on the mating surface is reduced (10.0µin versus 15.0µin), and overall contact length is marginally increased (0.450" versus 0.440"). These variations do not preclude functional substitution within the specified electrical and mechanical constraints. The PBC08DAAN is suitable for applications where multi-source component qualification is required or where extended temperature performance is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the 5-146256-8 be used as a direct replacement for the 5-146268-8?

A: Yes. The 5-146256-8 is functionally equivalent to the 5-146268-8 across all critical electrical and mechanical parameters. The primary difference is termination style (standard solder versus kinked pin solder). Both are compatible with standard through-hole PCB assembly processes. The 5-146256-8 is the manufacturer-recommended substitute and carries active product status.

Q: What is the difference between kinked pin and standard solder termination?

A: Kinked pin termination features a bent contact post designed to provide additional mechanical retention during PCB assembly. Standard solder termination uses a straight contact post. Both termination styles are compatible with wave soldering and reflow processes. Selection depends on specific assembly process requirements and PCB design specifications.

Q: Is the Sullins PBC08DAAN compatible with applications designed for the TE Connectivity 5-146268-8?

A: Yes. The PBC08DAAN maintains compatibility across all primary substitution criteria: 16-position, 2.54mm pitch, male pin contacts, through-hole mounting, 3A current rating, and UL94 V-0 flammability compliance. Secondary parameter variations (contact material, insulation material, contact finish thickness, and overall contact length) do not preclude functional substitution within the specified electrical and mechanical constraints.

Q: What is the significance of the extended operating temperature range on the PBC08DAAN?

A: The PBC08DAAN operates across -65°C to 125°C, compared to -65°C to 105°C for the TE Connectivity parts. This extended upper temperature limit provides additional thermal margin for applications subject to elevated ambient conditions or thermal cycling. Applications operating within the -65°C to 105°C range are fully compatible with all three connector options.

Q: Are all three connectors RoHS3 compliant?

A: Yes. The 5-146268-8, 5-146256-8, and PBC08DAAN are all ROHS3 compliant. All three connectors carry UL94 V-0 flammability ratings and are classified under HTSUS code 8536.69.4040.

Q: What is the difference in contact material between the TE Connectivity and Sullins connectors?

A: The TE Connectivity 5-146268-8 and 5-146256-8 use Copper Alloy contacts, while the Sullins PBC08DAAN uses Phosphor Bronze contacts. Both materials are suitable for 3A current applications and maintain equivalent electrical performance within the specified operating parameters.

Q: Does the insulation material difference affect connector performance?

A: The TE Connectivity connectors use Liquid Crystal Polymer (LCP) insulation, while the Sullins PBC08DAAN uses Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements and are suitable for the specified operating temperature ranges. Material selection reflects manufacturer design preferences and does not impact functional compatibility.

Q: What is the significance of the contact finish thickness variation?

A: The TE Connectivity connectors specify 15.0µin (0.38µm) gold plating on mating contacts, while the Sullins PBC08DAAN specifies 10.0µin (0.25µm). Both thicknesses provide adequate corrosion protection and electrical conductivity for 3A applications. The variation reflects different manufacturer specifications and does not preclude functional substitution.

Q: Are there any packaging differences between these connectors?

A: The 5-146268-8 packaging is not specified in available documentation. The 5-146256-8 is supplied in bulk packaging, as is the PBC08DAAN. Packaging format may affect procurement and inventory management but does not impact electrical or mechanical compatibility.

Q: What inventory considerations should guide part selection?

A: The 5-146256-8 has the highest inventory availability (5563 units in stock), followed by the PBC08DAAN (3972 units), and the obsolete 5-146268-8 (1150 units). For new designs and ongoing production, the 5-146256-8 is recommended due to active product status and superior availability. The PBC08DAAN provides a secondary source option for multi-source qualification strategies.
