Male pin contact type
Through-hole solder termination
Push-pull fastening mechanism
Square contact shape
UL94 V-0 flammability rating
Black insulation color
MSL 1 classification

Allowable Variations:

Contact material (Phosphor Bronze, Copper Alloy, Brass)

Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC 67996-372HLF

The 67996-372HLF is the direct active equivalent from the same manufacturer and series (BERGSTIK® II). It maintains identical position count, pitch, contact geometry, and termination method. The part is RoHS Compliant and carries active product status, ensuring long-term availability and supply chain stability. Contact post length differs minimally (0.095" vs. 0.110"), resulting in negligible overall contact length variation (0.425" vs. 0.440"). This part is the preferred substitution path for existing 68737-372HLF designs.

Secondary Recommendations: Sullins Connector Solutions PBC36DAAN

The PBC36DAAN offers the closest dimensional match among multi-source alternatives, with identical mating contact length (0.230"), matching insulation height (0.100"), and equivalent contact material (Phosphor Bronze). It is ROHS3 Compliant and REACH Unaffected, with 3A current rating and -65°C to 125°C operating range. Post length is 0.120" (vs. 0.110"), yielding overall contact length of 0.450" (vs. 0.440"), a 0.010" difference acceptable for standard through-hole board spacing. Inventory availability is substantial (8210 units).

Alternative Options: Molex 0010897721 and 0010897722

Both Molex C-Grid 70280 series parts maintain the critical 72-position, 2-row, 2.54mm pitch configuration with square contacts and push-pull fastening. The 0010897721 features tin mating finish, while 0010897722 provides gold mating finish. Insulation height is 0.090" (vs. 0.100"), and contact material is Copper Alloy rather than Phosphor Bronze. These parts are ROHS3 Compliant and suitable for applications where contact material substitution is acceptable. Connector style includes breakaway capability, offering design flexibility.

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

This part deviates from the original in contact shape (circular vs. square) and mating contact length (0.141" vs. 0.230"), making it suitable only for applications where contact geometry is not critical. It is ROHS3 Compliant and REACH Unaffected, with 3A current rating and -55°C to 125°C operating range. Use only when mechanical constraints permit circular contact substitution.

Sullins Connector Solutions GBC36DAAN, PBC36DABN, PBC36DACN, PBC36DADN, PBC36DAEN

These parts share the PBC36DAAN base specifications but feature extended post lengths (0.230" to 0.520"), resulting in overall contact lengths from 0.560" to 0.850". Selection depends on PCB thickness and stacking height requirements. All are ROHS3 Compliant. GBC36DAAN uses Polyamide (PA9T) insulation with -65°C to 150°C operating range. PBC36DABN, PBC36DACN, PBC36DADN, and PBC36DAEN use Polybutylene Terephthalate (PBT) insulation with -65°C to 125°C operating range. Choose based on specific board-to-board spacing and thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can I use PBC36DAAN as a direct replacement for 68737-372HLF?

A: Yes. Both parts maintain 72 positions, 2 rows, 0.100" (2.54mm) pitch, square male pin contacts, solder termination, and push-pull fastening. The post length difference (0.120" vs. 0.110") results in 0.010" additional overall contact length, which is within standard through-hole PCB tolerance. Verify that your PCB board-to-board spacing accommodates the 0.450" overall contact length.

Q: What is the difference between the Molex 0010897721 and 0010897722?

A: Both are identical C-Grid 70280 series headers with 72 positions at 2.54mm pitch. The primary difference is mating contact finish: 0010897721 features tin finish (150.0µin thickness), while 0010897722 features gold finish (15.0µin thickness). Select based on mating surface requirements and corrosion resistance needs.

Q: Why do some substitute parts have different contact post lengths?

A: Post length variation accommodates different PCB thicknesses and board-to-board spacing requirements. The Sullins PBC36 series offers five post length options (0.120" through 0.520") to support various stacking configurations. Select the post length matching your specific PCB assembly geometry.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed are RoHS Compliant or ROHS3 Compliant. The original 68737-372HLF does not specify RoHS status due to its obsolete classification. Verify RoHS compliance requirements for your application before final part selection.

Q: Can I use the Preci-Dip 450-V3-272-00-006101 as a substitute?

A: The Preci-Dip part maintains the critical 72-position, 2-row, 2.54mm pitch configuration but differs in contact shape (circular vs. square) and mating contact length (0.141" vs. 0.230"). Use only if your application does not depend on square contact geometry or if circular contacts are functionally equivalent for your mating connector.

Q: What is the inventory status of substitute parts?

A: Current inventory levels are: 67996-372HLF (864 units), 0010897721 (783 units), 0010897722 (928 units), 450-V3-272-00-006101 (988 units), GBC36DAAN (805 units), PBC36DAAN (8210 units), PBC36DABN (1136 units), PBC36DACN (1328 units), PBC36DADN (777 units), PBC36DAEN (1625 units). PBC36DAAN offers the highest availability.

Q: Do substitute parts support the same current and voltage ratings?

A: The original 68737-372HLF does not specify current or voltage ratings. Most active substitutes are rated for 3A per contact. Molex parts do not specify current or voltage ratings. Preci-Dip 450-V3-272-00-006101 is rated for 3A and 150VDC. Verify that substitute part ratings meet your application requirements.

Q: What operating temperature ranges are available?

A: Operating temperature ranges vary: Amphenol ICC 67996-372HLF (-65°C to 125°C), Molex parts (not specified), Preci-Dip 450-V3-272-00-006101 (-55°C to 125°C), Sullins GBC36DAAN (-65°C to 150°C), Sullins PBC36 series (-65°C to 125°C). Select based on your thermal environment requirements.
