Substitute Part Grouping Explanation

Substitution of the 68451-201H is determined by strict equivalence across the following critical parameters:

• Connector positioning and pitch: 34 positions, 2 rows, 0.100" (2.54mm) mating pitch and row spacing
• Mounting and termination: Through-hole, right-angle configuration with solder termination
• Fastening mechanism: Push-pull fastening type
• Contact geometry: Male pin, square contact shape
• Electrical and mechanical interface: Board-to-board style, unshrouded design

The Amphenol ICC 77317-112-34LF meets these substitution criteria. This part maintains identical position count, pitch spacing, mounting orientation, and termination method. The 77317-112-34LF is an active product within the BERGSTIK® series, providing a direct functional replacement for the obsolete 68451-201H.

Parameter Comparison

Engineering Selection Recommendations

The 77317-112-34LF is the appropriate substitute for the obsolete 68451-201H based on the following factors:

Product Status: The 68451-201H is classified as obsolete, making the active 77317-112-34LF the necessary replacement for new designs and ongoing procurement.

Compliance and Certifications: The 77317-112-34LF achieves RoHS compliance, whereas the 68451-201H is RoHS non-compliant. For applications subject to RoHS regulations, the 77317-112-34LF provides regulatory alignment. Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Functional Equivalence: The substitute part maintains identical electrical and mechanical interface specifications, including position count, pitch spacing, mounting configuration, and termination method. The breakaway feature of the 77317-112-34LF provides additional design flexibility without compromising core functionality.

Frequently Asked Questions (FAQ)

Q: Can the 77317-112-34LF directly replace the 68451-201H in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100" / 2.54mm), position count (34), row configuration (2 rows), mounting type (through-hole, right-angle), and termination method (solder). The mechanical and electrical interfaces are equivalent.

Q: What is the difference between the BERGSTIK® II and BERGSTIK® series designations?

A: The 68451-201H belongs to the BERGSTIK® II series, while the 77317-112-34LF belongs to the BERGSTIK® series. Both are Amphenol ICC rectangular connector families. The series designation reflects product line evolution; the substitute part represents the current active product line.

Q: Does the breakaway feature of the 77317-112-34LF affect compatibility?

A: No. The breakaway feature is an additional capability that does not alter the core connector interface. The 77317-112-34LF maintains full compatibility with mating connectors designed for the 68451-201H.

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

A: The 68451-201H has a mating contact length of 0.400" (10.16mm), while the 77317-112-34LF has a mating contact length of 0.268" (6.80mm). Both maintain the same insulation height of 0.190" (4.83mm). Verify that the shorter mating contact length of the substitute part is compatible with your mating connector design.

Q: Are there RoHS compliance implications for substitution?

A: Yes. The 77317-112-34LF is RoHS compliant, whereas the 68451-201H is RoHS non-compliant. If your application or market requires RoHS compliance, the 77317-112-34LF satisfies this requirement.

Q: What is the current rating difference?

A: The 77317-112-34LF specifies a current rating of 3A per contact. The 68451-201H does not provide a current rating specification. Ensure that 3A per contact meets your application requirements.
