Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68737-372 is determined by the following critical parameters:

Primary Matching Criteria:

• Number of Positions: 72
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Current Rating: 3A minimum
• Material Flammability Rating: UL94 V-0

Secondary Compatibility Parameters:

• Operating Temperature range (minimum -55°C, maximum 105°C or higher)
• Contact Shape (Square or Circular acceptable)
• Insulation Height tolerance (0.100" ± acceptable variance)
• Overall Contact Length (within mechanical envelope constraints)

Three substitute parts meet these criteria with varying compliance and availability profiles.

Parameter Comparison

Engineering Selection Recommendations

Amphenol ICC 67996-372HLF is the primary direct substitute. This part maintains identical electrical and mechanical specifications to the 68737-372 while offering active product status and RoHS compliance. The 67996-372HLF is from the same manufacturer and BERGSTIK® II series, ensuring design compatibility with minimal risk. Operating temperature range of -65°C ~ 125°C covers most applications within the original specification envelope.

3M 2372-6121-TG provides an alternative from a different manufacturer within the 2300 series. This connector maintains the 72-position, 2-row configuration with identical pitch and current rating. The operating temperature range of -55°C ~ 105°C is narrower than the original specification, requiring thermal envelope verification for applications requiring extended low-temperature operation below -55°C or high-temperature operation above 105°C. RoHS non-compliance status matches the original part.

Preci-Dip 450-V3-272-00-006101 offers ROHS3 compliance and active product status. This connector features circular contact geometry versus the square contacts of the original part, which may affect mating force characteristics and contact resistance. The insulation height of 0.110" (2.79mm) represents a 0.010" increase from the original specification, requiring mechanical envelope verification in space-constrained applications. Operating temperature range of -55°C ~ 125°C and voltage rating of 150VDC are specified parameters.

Selection should prioritize the 67996-372HLF for direct replacement applications. Alternative selections require design verification for thermal, mechanical, and electrical envelope compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 67996-372HLF directly replace the 68737-372 without design changes?

A: Yes. The 67996-372HLF maintains identical electrical and mechanical specifications including pitch, position count, row spacing, current rating, and flammability rating. Both parts are from Amphenol ICC and the BERGSTIK® II series. The primary difference is product status (active versus obsolete) and RoHS compliance.

Q: What is the key difference between the 68737-372 and the 3M 2372-6121-TG?

A: The 3M connector operates within a narrower temperature range (-55°C ~ 105°C versus -65°C ~ 130°C). Applications requiring operation below -55°C or above 105°C require thermal analysis. The 3M part uses copper alloy contacts with tin-lead post finish versus phosphor bronze contacts in the original part.

Q: Why does the Preci-Dip 450-V3-272-00-006101 have a different insulation height?

A: The Preci-Dip connector specifies 0.110" (2.79mm) insulation height compared to 0.100" (2.54mm) for the original part. This 0.010" difference may affect board layout and mating interface clearances. Mechanical envelope verification is required before substitution in space-constrained designs.

Q: What is the significance of contact shape differences (square versus circular)?

A: Contact shape affects mating force, contact resistance, and wear characteristics. Square contacts (68737-372, 67996-372HLF, 2372-6121-TG) provide different engagement mechanics than circular contacts (450-V3-272-00-006101). Mating interface compatibility must be verified when substituting between different contact geometries.

Q: Are all substitute parts RoHS compliant?

A: No. The 67996-372HLF is RoHS Compliant. The 450-V3-272-00-006101 is ROHS3 Compliant. The 2372-6121-TG is RoHS non-compliant, matching the original part status. Regulatory requirements for your application determine compliance necessity.

Q: What packaging options are available for these connectors?

A: The 68737-372 packaging is not specified. The 67996-372HLF is supplied in Bag packaging. The 2372-6121-TG packaging is not specified. The 450-V3-272-00-006101 is supplied in Bulk packaging. Packaging selection affects handling, storage, and inventory management procedures.

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

A: Only the Preci-Dip 450-V3-272-00-006101 specifies a voltage rating of 150VDC. The original part and other substitutes do not provide voltage rating specifications. Applications with specific voltage requirements must reference the Preci-Dip part or obtain voltage ratings from manufacturers for other options.
