Amphenol ICC 69157-372 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 69157-372 is a rectangular connector header featuring 72 positions at 0.100" (2.54mm) pitch, designed for through-hole board-to-board applications. This component is classified as obsolete, necessitating identification of active equivalent parts that maintain electrical and mechanical compatibility. Substitute parts must preserve the 72-position configuration, 2.54mm pitch, 3A current rating, and through-hole solder termination to ensure functional interchangeability in existing designs.

Engineering Selection Recommendations

Primary Recommendation: PEC36DAAN (Sullins Connector Solutions)

PEC36DAAN is the optimal substitute based on product status, compliance, and availability. This part is active, ROHS3 compliant, and maintains all critical electrical and mechanical parameters. With 13,229 units in stock, it provides supply security. The tin contact finish on the mating surface differs from the original gold finish but remains functionally compatible for standard applications. Operating temperature range of -65°C to 125°C covers the original specification's lower bound.

Secondary Recommendation: PBC36DAAN (Sullins Connector Solutions)

PBC36DAAN offers an alternative with gold contact finish on the mating surface, matching the original specification more closely. This part is active and ROHS3 compliant with 8,210 units in inventory. Operating temperature range is -65°C to 125°C. The gold finish provides enhanced corrosion resistance for applications requiring extended shelf life or high-reliability environments.

Alternative for Extended Temperature Range: GBC36DAAN (Sullins Connector Solutions)

GBC36DAAN extends the operating temperature range to -65°C to 150°C, exceeding the original specification. This part is active, ROHS3 compliant, and features gold contact finish. With 805 units in stock, it suits applications requiring thermal margin beyond standard requirements.

Preci-Dip 450-V3-272-00-006101 Consideration

The Preci-Dip part maintains active status and ROHS3 compliance but operates at -55°C to 125°C, which does not fully encompass the original -65°C lower limit. This part is suitable only for applications where the lower temperature bound is not critical. Contact shape is circular rather than square, which may affect mating characteristics in legacy designs.

Samtec DW-36-07-L-D-200 Consideration

The Samtec part is active and ROHS3 compliant but lacks specified operating temperature data. This information gap presents a risk for temperature-critical applications. The part is suitable for applications where thermal specifications are not a design constraint.

Frequently Asked Questions (FAQ)

Q: Can I use PEC36DAAN as a direct replacement for 69157-372?

A: Yes. PEC36DAAN maintains the 72-position, 2-row, 2.54mm pitch configuration with through-hole solder termination and 3A current rating. The tin contact finish on the mating surface differs from the original gold finish but provides equivalent electrical performance for standard applications. Operating temperature range of -65°C to 125°C covers the original specification's lower bound.

Q: What is the difference between gold and tin contact finishes?

A: Gold provides superior corrosion resistance and is preferred for high-reliability or long-shelf-life applications. Tin offers adequate performance for standard applications and is more cost-effective. Both finishes maintain equivalent electrical conductivity and current-carrying capacity at the specified 3A rating.

Q: Why do some substitute parts have longer post lengths?

A: Post length variations (0.110" to 0.820") accommodate different PCB thicknesses and stacking configurations. Longer posts allow connection through thicker boards or multiple stacked connectors. Selection depends on your specific PCB thickness and mechanical assembly requirements. Shorter posts (0.120" to 0.230") are suitable for standard single-board applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant, whereas the original 69157-372 is RoHS non-compliant. This compliance upgrade is beneficial for new designs and regulatory requirements.

Q: What is the significance of the operating temperature range differences?

A: The original part operates from -65°C to 130°C. Most substitute parts operate from -65°C to 125°C, which covers the original range except for the upper 5°C margin. GBC36DAAN extends to 150°C for applications requiring additional thermal margin. Preci-Dip 450-V3-272-00-006101 operates from -55°C to 125°C and does not meet the original -65°C lower limit.

Q: Can I mix different substitute parts in the same design?

A: All substitute parts maintain identical electrical and mechanical compatibility at the connector interface. However, post length variations affect PCB assembly and stacking height. Consistent post length selection within a design is recommended to maintain uniform mechanical characteristics.

Q: What inventory levels should I consider?

A: PEC36DAAN offers the highest inventory (13,229 units), followed by PBC36DAAN (8,210 units). These parts provide supply security for production volumes. Preci-Dip 450-V3-272-00-006101 (988 units) and Samtec DW-36-07-L-D-200 (1,115 units) offer moderate availability.
