Amphenol ICC 68463-172 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68463-172 is a rectangular connector header featuring a right-angle, through-hole mount configuration with 72 positions at 0.100" (2.54mm) pitch. This BERGSTIK® II series connector is designed for board-to-board applications with unshrouded, male pin contacts and solder termination. The part is currently active in production with 762 units in stock. Substitute parts are necessary when addressing obsolescence concerns, compliance requirements, or specific application constraints such as operating temperature ranges or contact finish specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68463-172 is determined by the following critical parameters:

• Pitch and Position Count: Substitute parts must maintain 0.100" (2.54mm) mating pitch and support 72 positions in a 2-row configuration to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Mounting Configuration: Right-angle, through-hole mounting is required to match the original application footprint and board integration method.
• Contact Type and Termination: Male pin contacts with solder termination are mandatory for compatibility with standard header receptacles and assembly processes.
• Connector Style: Board-to-board or board-to-cable capable headers are acceptable, as they maintain the same mating interface.
• Shrouding and Fastening: Unshrouded design with push-pull fastening must be preserved for mechanical fit and retention.

Two substitute parts meet these criteria:

1. TE Connectivity AMP Connectors 4-103149-0: Meets core pitch, mounting, and contact specifications. Position count is 80 (exceeds 72), which may require design verification for PCB layout compatibility.
2. Samtec Inc. TSW-136-10-G-D-RA: Matches all critical parameters including 72-position count, pitch, mounting type, and contact configuration.

Parameter Comparison

Engineering Selection Recommendations

Samtec TSW-136-10-G-D-RA is the preferred substitute for new designs and applications requiring compliance with current environmental standards. This part maintains exact position and pitch compatibility with the 68463-172, operates across a wider temperature range (-55°C to 125°C), and carries ROHS3 compliance status. The extended contact post length (0.390" vs. 0.110") must be evaluated against PCB clearance and assembly requirements.

TE Connectivity 4-103149-0 is an alternative for applications where the 80-position configuration can be accommodated within the PCB layout. This part is marked obsolete, which may present long-term supply chain risk. The increased insulation height (0.238" vs. 0.190") and different contact post length (0.120") require mechanical verification. RoHS non-compliance status matches the original part.

For applications with strict compliance mandates, the Samtec part is the only option among the three. For applications where RoHS compliance is not required and the 80-position layout is acceptable, the TE Connectivity part remains functionally viable.

Frequently Asked Questions (FAQ)

Q: Can the 4-103149-0 be used as a direct replacement for the 68463-172?

A: The 4-103149-0 shares the same 0.100" (2.54mm) pitch and mounting type but has 80 positions instead of 72. Direct substitution requires PCB layout verification to confirm that the additional 8 positions do not conflict with existing board design. The increased insulation height (0.238" vs. 0.190") may also affect clearance in confined spaces.

Q: What is the primary difference between the Samtec TSW-136-10-G-D-RA and the original 68463-172?

A: The Samtec part maintains identical position count (72) and pitch (0.100"), ensuring mechanical compatibility. Key differences include ROHS3 compliance (vs. non-compliant), wider operating temperature range (-55°C to 125°C vs. unspecified), and a significantly longer contact post (0.390" vs. 0.110"). The thinner gold finish on the mating contact (10.0µin vs. 30.0µin) is within acceptable tolerances for standard applications.

Q: Why does the TE Connectivity part show obsolete status?

A: Obsolete status indicates the part is no longer in active production. While 1112 units are currently in stock, future availability cannot be guaranteed. For new designs or long-term production requirements, the active-status Samtec part is recommended.

Q: Are there mechanical compatibility issues with the different contact post lengths?

A: Contact post length affects solder joint formation and PCB hole depth requirements. The 68463-172 (0.110"), 4-103149-0 (0.120"), and TSW-136-10-G-D-RA (0.390") have different post lengths. Standard PCB designs typically accommodate post lengths up to 0.390" without issue. Verify your PCB design specifications and soldering process parameters before substitution.

Q: Does the contact finish thickness affect electrical performance?

A: Contact finish thickness (30.0µin for 68463-172 and 4-103149-0 vs. 10.0µin for TSW-136-10-G-D-RA) impacts contact durability and mating cycles. The Samtec part's thinner finish is suitable for standard applications with moderate mating cycles. High-cycle applications or harsh environments may benefit from the thicker finish of the original or TE Connectivity parts.

Q: Which substitute part is best for RoHS-compliant applications?

A: The Samtec TSW-136-10-G-D-RA is ROHS3 compliant and is the only option among the three parts that meets current environmental regulations. Both the original 68463-172 and TE Connectivity 4-103149-0 are RoHS non-compliant.
