Amphenol ICC 68000-603 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68000-603 is a rectangular connector header designed for through-hole mounting applications. This 3-position, single-row connector operates at 0.100" (2.54mm) pitch and supports 3A per contact with an operating temperature range of -65°C to 125°C. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the 68000-603 is determined by strict alignment with the following electrical and mechanical parameters:

Connector type classification (Header)
Contact gender (Male Pin)
Mating pitch (0.100" / 2.54mm)
Position count (3 positions, single row)
Mounting method (Through Hole)
Termination type (Solder)
Current capacity (3A minimum per contact)
Operating temperature range (minimum -65°C to 105°C)
Flammability rating (UL94 V-0)

The TE Connectivity AMP Connectors part 5-146285-3 meets all substitution criteria within these parameters.

Engineering Selection Recommendations

The TE Connectivity 5-146285-3 is the designated substitute for the obsolete Amphenol ICC 68000-603. Both connectors share identical mating pitch, position count, contact type, and current rating specifications. The substitute maintains equivalent electrical performance and mechanical compatibility for board-to-board applications.

The 5-146285-3 offers the advantage of active product status with ROHS3 compliance, addressing regulatory requirements for new designs. The operating temperature upper limit of 105°C on the substitute is suitable for applications not requiring the extended 125°C capability of the original part.

Minor dimensional variations exist in contact post length (0.090" versus 0.095") and overall contact length (0.410" versus 0.425"), which remain within acceptable tolerances for standard through-hole PCB mounting. Contact material differs (Copper Alloy versus Phosphor Bronze) but maintains equivalent electrical conductivity and contact reliability at the specified 3A rating.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-146285-3 directly replace the Amphenol ICC 68000-603 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (3), contact type (Male Pin), and current rating (3A). Through-hole mounting and solder termination are identical. The substitute is mechanically and electrically compatible for board-to-board applications.

Q: What is the significance of the "Breakaway" designation on the substitute part?

A: The breakaway feature on the 5-146285-3 allows individual positions to be separated if required, providing design flexibility. This does not affect compatibility with the original application, as the connector functions identically in non-breakaway configurations.

Q: Does the lower operating temperature maximum (105°C vs. 125°C) affect compatibility?

A: The substitute's 105°C upper limit is suitable for standard industrial and consumer applications. Applications requiring sustained operation above 105°C would require alternative component selection.

Q: Are there differences in contact finish specifications?

A: Both parts specify gold mating contact finish at 30.0µin (0.76µm) thickness. The substitute includes tin finish on the post, whereas the original does not specify post finish. Both finishes are standard for solder termination and do not affect electrical performance.

Q: What is the impact of RoHS compliance differences?

A: The original 68000-603 is RoHS non-compliant, while the 5-146285-3 is ROHS3 compliant. For new designs subject to RoHS regulations, the substitute is the appropriate selection. Existing legacy systems may continue using either part based on regulatory requirements.

Q: Are there inventory considerations for this substitution?

A: The 5-146285-3 has significantly higher inventory availability (64,795 pcs) compared to the obsolete 68000-603 (1,070 pcs), making it the practical choice for ongoing procurement.
