Engineering Selection Recommendations

Primary Substitute - Direct Replacement: The 68602-172HLF from Amphenol ICC (FCI) is the direct successor to the 68602-172H. Both parts share identical mechanical and electrical specifications within the BERGSTIK® II series. The 68602-172HLF is currently in active production status with higher inventory availability (1454 units) compared to the obsolete 68602-172H (758 units). The 68602-172HLF achieves RoHS compliance and provides an extended operating temperature range of -65°C to 130°C with a rated current of 3A, making it the preferred choice for new designs and production continuity.

Secondary Substitutes - Functional Equivalents: The 3M 2372-6121-TG, Preci-Dip 450-V3-272-00-006101, and Samtec DW-36-07-L-D-200 maintain the critical 72-position, 2.54mm pitch header configuration with through-hole solder termination and push-pull fastening. These alternatives differ in contact geometry, material composition, and compliance certifications:

The 3M 2372-6121-TG maintains square contact geometry and operates across -55°C to 105°C with 3A current rating. RoHS non-compliance aligns with the original 68602-172H specification.
The Preci-Dip 450-V3-272-00-006101 features circular contacts and achieves ROHS3 compliance with -55°C to 125°C operating range and 150VDC voltage rating. Contact length variations require mechanical verification for PCB compatibility.
The Samtec DW-36-07-L-D-200 is a stacking header variant with reduced overall pin length (0.430") and includes a 0.200" stack height specification. ROHS3 compliance and REACH unaffected status support regulatory requirements.

Selection among secondary substitutes depends on specific application requirements regarding contact geometry tolerance, operating temperature range, voltage rating, and compliance certifications. Mechanical fit verification on existing PCB designs is required when contact length or insulation height differs from the original 68602-172H specification.

Frequently Asked Questions (FAQ)

Q: Can the 68602-172HLF directly replace the 68602-172H without PCB modification?

A: Yes. The 68602-172HLF maintains identical pitch (0.100" / 2.54mm), position count (72), row configuration (2 rows), contact geometry (square), and overall dimensions as the 68602-172H. No PCB layout changes are required for direct substitution.

Q: What is the primary difference between the 68602-172H and 68602-172HLF?

A: The 68602-172HLF is the active production variant with RoHS compliance, extended operating temperature range (-65°C to 130°C versus unspecified for the original), and specified current rating (3A). The 68602-172H is obsolete. Both are BERGSTIK® II series connectors with identical mechanical specifications.

Q: Are the 3M, Preci-Dip, and Samtec alternatives pin-compatible with the original 68602-172H?

A: All substitute parts maintain the 72-position, 2.54mm pitch configuration and through-hole solder termination, ensuring electrical connectivity. However, variations in overall contact length (ranging from 0.394" to 0.480") and insulation height may affect mechanical fit on existing PCBs. Physical verification is required before production implementation.

Q: Why does the Preci-Dip 450-V3-272-00-006101 have circular contacts instead of square?

A: Contact shape is a design characteristic of the Preci-Dip 450 series. Circular contacts provide equivalent electrical performance in 2.54mm pitch applications but may have different insertion force and retention characteristics. Application-specific testing is recommended if contact geometry is critical to system performance.

Q: Which substitute offers the best compliance for new designs?

A: The 68602-172HLF (Amphenol ICC) and 450-V3-272-00-006101 (Preci-Dip) both achieve RoHS compliance. The Preci-Dip part additionally achieves ROHS3 compliance and carries REACH unaffected status, providing the highest regulatory alignment for new product development. The Samtec DW-36-07-L-D-200 also achieves ROHS3 compliance but includes stacking height specifications suitable for specific form factor requirements.

Q: What packaging options are available for these substitutes?

A: The 68602-172HLF is supplied in bag packaging. The Preci-Dip 450-V3-272-00-006101 is supplied in bulk packaging. The 3M 2372-6121-TG and Samtec DW-36-07-L-D-200 packaging specifications are not detailed in the provided data. Confirm packaging requirements with component suppliers for procurement planning.

Q: Can these connectors be used in applications requiring 150VDC voltage rating?

A: The Preci-Dip 450-V3-272-00-006101 is rated for 150VDC. The 68602-172H, 68602-172HLF, 3M 2372-6121-TG, and Samtec DW-36-07-L-D-200 do not specify voltage ratings in the provided data. Voltage rating verification is required for high-voltage applications.

Q: What is the operating temperature range for each substitute?

A: The 68602-172HLF operates from -65°C to 130°C. The 3M 2372-6121-TG and Preci-Dip 450-V3-272-00-006101 operate from -55°C to 105°C and -55°C to 125°C respectively. The original 68602-172H and Samtec DW-36-07-L-D-200 do not specify operating temperature ranges. Select substitutes based on application temperature requirements.
