Equivalent & Substitute Parts for 68452-172HLF

Part Overview

The 68452-172HLF is a rectangular connector header manufactured by Amphenol ICC (FCI) in the BERGSTIK® II series. This through-hole, right-angle connector features 72 positions at 0.100" (2.54mm) pitch with male pin contacts and push-pull fastening. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the 68452-172HLF is determined by strict equivalence across the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (72)
Number of rows (2)
Pitch - mating (0.100" / 2.54mm)
Row spacing - mating (0.100" / 2.54mm)
Mounting type (Through Hole, Right Angle)
Termination (Solder)
Fastening type (Push-Pull)
Contact shape (Square)
Material flammability rating (UL94 V-0)
Insulation color (Black)

The identified substitute parts meet all these core requirements and are therefore electrically and mechanically compatible with the original 68452-172HLF connector header.

Engineering Selection Recommendations

Both substitute parts are active products and provide direct functional equivalence to the obsolete 68452-172HLF. Selection between them depends on regulatory and compliance requirements:

The 2372-5221-TG (3M) is rated for -55°C to 105°C operation with a 3A current rating and carries a UL94 V-0 flammability rating. This part is RoHS non-compliant and REACH affected.

The TSW-136-25-S-D-RA (Samtec Inc.) is rated for -55°C to 125°C operation, carries a UL94 V-0 flammability rating, and is ROHS3 compliant. This part offers the widest operating temperature range and meets current RoHS3 requirements.

For applications requiring RoHS3 compliance and extended temperature operation, the TSW-136-25-S-D-RA is the preferred substitute. For applications with less stringent compliance requirements, the 2372-5221-TG provides an alternative with specified current rating.

Frequently Asked Questions (FAQ)

Q: Can the 2372-5221-TG or TSW-136-25-S-D-RA be used as direct replacements for the 68452-172HLF?

A: Yes. Both parts meet all critical electrical and mechanical parameters: 72-position, 2-row header with 0.100" (2.54mm) pitch, male pin contacts, through-hole right-angle mounting, solder termination, and push-pull fastening. All three parts carry UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels.

Q: What are the differences in contact length between these parts?

A: The 68452-172HLF has a mating contact length of 0.380" (9.65mm), while the 2372-5221-TG and TSW-136-25-S-D-RA have mating contact lengths of 0.318" (8.08mm) and 0.320" (8.13mm) respectively. These variations may affect mating depth and should be evaluated for specific board-to-board spacing requirements.

Q: Which substitute part has better compliance certifications?

A: The TSW-136-25-S-D-RA is ROHS3 compliant, meeting current regulatory requirements. The 2372-5221-TG is RoHS non-compliant and REACH affected. For new designs or applications requiring current compliance standards, the TSW-136-25-S-D-RA is the appropriate choice.

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

A: The 68452-172HLF does not specify an operating temperature range. The 2372-5221-TG operates from -55°C to 105°C. The TSW-136-25-S-D-RA operates from -55°C to 125°C, providing a wider temperature envelope.

Q: Are there differences in contact finish specifications?

A: The 68452-172HLF and TSW-136-25-S-D-RA both have gold mating contact finish at 30.0µin (0.76µm) thickness. The 2372-5221-TG has gold mating contact finish at 10.0µin (0.25µm) thickness, which is thinner. For applications requiring robust contact durability, the thicker gold finish of the 68452-172HLF and TSW-136-25-S-D-RA may be preferable.

Q: Does the 2372-5221-TG specify a current rating?

A: Yes. The 2372-5221-TG is rated for 3A per contact. The 68452-172HLF and TSW-136-25-S-D-RA do not specify current ratings in the provided data.
