Substitute Part Grouping Explanation

Substitution of the TE Connectivity 146268-4 is determined by strict equivalence across the following critical parameters: connector type (Header, Breakaway), contact type (Male Pin), number of positions (8), number of rows (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting type (Through Hole), contact length specifications (mating 0.230", post 0.120", overall 0.440"), insulation height (0.090"), contact shape (Square), contact material (Copper Alloy), insulation material (Liquid Crystal Polymer), operating temperature range (-65°C ~ 105°C), current rating (3A), and flammability rating (UL94 V-0).

Substitute parts are grouped into two categories:

Direct TE Connectivity Equivalents: Parts maintaining identical specifications with variations limited to contact finish post material (Tin versus Tin-Lead) and RoHS compliance status. These parts share the AMPMODU Mod II series designation and are sourced from the same manufacturer.

Cross-Manufacturer Alternatives: Samtec Inc. TD series connectors that maintain electrical and mechanical compatibility through identical pitch, position count, row configuration, mounting method, and contact specifications. These parts provide functional interchangeability while originating from a different manufacturer.

Parameter Comparison

Engineering Selection Recommendations

Direct TE Connectivity Equivalent (5-146268-4): This part maintains complete electrical and mechanical compatibility with the original 146268-4 specification. The primary distinction is the contact finish post material change from Tin-Lead to Tin and achievement of ROHS3 compliance. This part is designated as obsolete but remains available in inventory. Selection of this equivalent is appropriate for applications requiring strict adherence to original specifications with improved environmental compliance.

Recommended Active Replacement (5-146256-4): This TE Connectivity part is the manufacturer-recommended successor, maintaining all critical electrical and mechanical parameters while achieving active product status. The termination specification differs from the original (Solder versus Kinked Pin, Solder), but this change does not affect electrical performance or mechanical fit. This part achieves ROHS3 compliance and REACH unaffected status, providing superior long-term supply chain stability. Inventory availability is substantially higher at 3010 pieces. This part is the preferred selection for new designs and production continuity.

Cross-Manufacturer Samtec Alternatives (TD-104 Series): The Samtec TD-104 series connectors provide functional interchangeability through identical pitch, position count, row configuration, and mounting specifications. These parts are all active products with ROHS3 compliance. Selection between gold-plated (TD-104-G-A-1, TD-104-G-A-2) and tin-plated (TD-104-T-A-1, TD-104-T-A-2, TD-104-T-AA) variants depends on application contact resistance requirements and solderability specifications. These alternatives are suitable for applications where cross-manufacturer sourcing is acceptable and provide enhanced supply chain flexibility.

Frequently Asked Questions (FAQ)

Q: What is the primary reason the 146268-4 requires substitution?

A: The 146268-4 is designated as obsolete. While current inventory exists, long-term availability cannot be assured. Substitution ensures design continuity and production sustainability through active product alternatives.

Q: Are the TE Connectivity equivalents (5-146268-4 and 5-146256-4) electrically identical to the original 146268-4?

A: Both equivalents maintain identical electrical specifications including 8 positions, 2.54mm pitch, 3A current rating, and -65°C to 105°C operating temperature range. The 5-146268-4 differs only in contact finish post material (Tin versus Tin-Lead) and RoHS compliance. The 5-146256-4 additionally specifies standard solder termination rather than kinked pin solder termination, but this does not affect electrical performance.

Q: Can Samtec TD-104 series connectors be used as direct replacements?

A: Samtec TD-104 connectors are functionally compatible based on identical pitch (2.54mm), position count (8), row configuration (2 rows), and through-hole mounting. However, detailed mechanical specifications such as contact length dimensions are not provided for the Samtec parts. Verification of mechanical fit within the specific application is required before implementation.

Q: What is the difference between TD-104-G-A and TD-104-T-A variants?

A: The primary distinction is contact finish material. TD-104-G-A variants feature gold-plated mating contacts (20.0µin thickness), while TD-104-T-A and TD-104-T-AA variants feature tin-plated mating contacts (200.0µin thickness). Gold plating provides superior corrosion resistance and lower contact resistance, while tin plating offers cost efficiency and standard solderability characteristics.

Q: Which substitute part offers the best long-term supply chain stability?

A: The 5-146256-4 is the manufacturer-recommended active product with the highest inventory availability (3010 pieces) and active product status. This part provides the strongest assurance of continued availability and represents the optimal selection for new designs and production planning.

Q: Are all substitute parts RoHS3 compliant?

A: The original 146268-4 is RoHS non-compliant. All substitute parts listed (5-146268-4, 5-146256-4, and all Samtec TD-104 variants) are ROHS3 compliant, meeting current environmental regulatory requirements.

Q: What is the MSL rating for the Samtec alternatives?

A: Moisture Sensitivity Level (MSL) specifications are not provided for the Samtec TD-104 series connectors. Contact the manufacturer directly for MSL classification if moisture sensitivity is a critical parameter for your application environment.

Q: Can the kinked pin termination of the original 146268-4 be replaced with standard solder termination?

A: Yes. The 5-146256-4 specifies standard solder termination without kinked pins. This change does not affect electrical performance or mechanical compatibility. The kinked pin feature provides mechanical retention during assembly; standard solder termination relies solely on solder joint integrity.

Q: What inventory quantities are available for each substitute part?

A: Current inventory levels are: 5-146268-4 (663 pieces), 5-146256-4 (3010 pieces), TD-104-G-A-1 (902 pieces), TD-104-G-A-2 (806 pieces), TD-104-T-A-1 (1118 pieces), TD-104-T-A-2 (924 pieces), and TD-104-T-AA (1168 pieces). The 5-146256-4 offers the highest availability.
