Amphenol ICC 68459-140 Rectangular Connector Header – Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68459-140 is a through-hole, right-angle rectangular connector header with 40 positions at 0.100" (2.54mm) pitch, configured as a 2-row board-to-board interface. This BERGSTIK® II series component features male pins with gold-plated mating contacts and phosphor bronze construction, designed for standard PCB interconnection applications.

The 68459-140 maintains active product status with 805 units in current inventory. Equivalent and substitute parts are identified based on matching electrical and mechanical parameters: 0.100" pitch, 40-position 2-row configuration, through-hole right-angle mounting, push-pull fastening, and board-to-board connectivity. Substitutes are necessary when addressing supply chain constraints, design revisions, or specific compliance requirements across different manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the 68459-140 is determined by strict adherence to the following core parameters:

Critical Matching Parameters:

Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 40
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole, Right Angle
Connector Type: Header
Contact Type: Male Pin
Style: Board to Board or Board to Board/Cable
Shrouding: Unshrouded

Engineering Selection Recommendations

Primary Selection (Active Status, Current Supply):

The TSW-120-25-G-D-RA (Samtec) and TSW-120-25-T-D-RA (Samtec) are preferred substitutes when the 68459-140 is unavailable. Both maintain active product status with robust inventory levels (907 and 962 units respectively). The TSW-120-25-G-D-RA features gold mating contact finish matching the original specification, while the TSW-120-25-T-D-RA provides tin finish as an alternative. Both Samtec variants achieve ROHS3 compliance and support extended operating temperature ranges (-55°C to 125°C and -55°C to 105°C respectively), providing design flexibility for thermal environments.

Secondary Selection (Active Status, Manufacturer Recommended):

The Hirose A1-40PA-2.54DS(71) is designated as manufacturer-recommended and maintains active product status with 922 units in inventory. This part achieves RoHS compliance and specifies 200V voltage rating with 3A current rating. Operating temperature range is -55°C to 85°C. The A1 series uses polybutylene terephthalate (PBT) insulation material with brass contact construction.

Tertiary Selection (Obsolete Status, Legacy Applications):

The TE Connectivity 7-146311-0 is classified as obsolete and should be selected only when legacy design compatibility or existing inventory constraints require it. This part is RoHS compliant with 913 units available. The AMPMODU Mod II series supports both press-fit and solder termination options, providing additional assembly flexibility. Operating temperature range is -65°C to 105°C with 3A current rating.

Compliance Considerations:

The original 68459-140 is RoHS non-compliant. All substitute parts except the 68459-140 itself achieve RoHS compliance (RoHS Compliant or ROHS3 Compliant status). Design revisions requiring RoHS compliance should specify Samtec TSW-120 series or Hirose A1-40PA variants.

Frequently Asked Questions (FAQ)

Q: Can the TSW-120-25-G-D-RA directly replace the 68459-140 without PCB redesign?

A: Yes. Both parts share identical pitch (0.100"), position count (40), row configuration (2 rows), row spacing (0.100"), mounting type (through-hole right-angle), and fastening mechanism (push-pull). PCB footprints are compatible. Minor variations in contact length and insulation height do not affect board-level compatibility.

Q: What is the difference between TSW-120-25-G-D-RA and TSW-120-25-T-D-RA?

A: The primary difference is mating contact finish. The TSW-120-25-G-D-RA features gold mating contacts (10.0µin thickness), while the TSW-120-25-T-D-RA uses tin mating contacts. Both share identical pitch, position count, row spacing, and mounting configuration. Contact finish selection depends on application requirements and corrosion resistance specifications.

Q: Why is the TE Connectivity 7-146311-0 marked as obsolete?

A: Obsolete status indicates the part is no longer in active production by the manufacturer. While 913 units remain in current inventory, long-term availability cannot be guaranteed. Active alternatives (Samtec TSW-120 series, Hirose A1-40PA) are recommended for new designs.

Q: Does the Hirose A1-40PA-2.54DS(71) support the same current and voltage ratings as the 68459-140?

A: The Hirose part specifies 3A current rating and 200V voltage rating. The original 68459-140 does not provide current or voltage specifications in the available data. The Hirose ratings represent the component's electrical capability and are suitable for standard PCB interconnection applications.

Q: Are all substitute parts UL94 V-0 rated?

A: Yes. All identified substitute parts (7-146311-0, A1-40PA-2.54DS(71), TSW-120-25-G-D-RA, TSW-120-25-T-D-RA) maintain UL94 V-0 material flammability rating, matching the original 68459-140 specification.

Q: What is the operating temperature range difference between substitutes?

A: Operating temperature ranges vary: 68459-140 (not specified), 7-146311-0 (-65°C to 105°C), A1-40PA-2.54DS(71) (-55°C to 85°C), TSW-120-25-G-D-RA (-55°C to 125°C), TSW-120-25-T-D-RA (-55°C to 105°C). Select based on application thermal requirements.

Q: Can the 7-146311-0 be used in new designs despite obsolete status?

A: The 7-146311-0 is electrically and mechanically compatible with the 68459-140. However, obsolete status presents supply chain risk. New designs should specify active alternatives (Samtec or Hirose) to ensure long-term component availability and manufacturing support.

Q: What packaging formats are available for these substitutes?

A: 68459-140 (Bulk), 7-146311-0 (not specified), A1-40PA-2.54DS(71) (Tray), TSW-120-25-G-D-RA (Bulk), TSW-120-25-T-D-RA (Bulk). Packaging selection may affect procurement and assembly processes.
