Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 75168-316-36 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (36)
• Number of rows (1)
• Pitch - mating (0.100" / 2.54mm)
• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Contact shape (Square)
• Contact material (Phosphor Bronze)
• Insulation material (Thermoplastic)
• Shrouding (Unshrouded)
• Style (Board to Board)
• Fastening type (Push-Pull)
• Material flammability rating (UL94 V-0)
• Insulation color (Black)

The identified substitute maintains all critical mechanical and electrical interface parameters, with variations limited to contact finish specifications and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The 75168-316-36LF serves as the direct active-production equivalent to the obsolete 75168-316-36. Both parts maintain identical mechanical and electrical interface specifications, ensuring pin-for-pin compatibility in board-to-board applications.

The primary distinction between these parts is product status and regulatory compliance. The 75168-316-36LF is actively manufactured and RoHS compliant, whereas the original part is obsolete and RoHS non-compliant. The contact finish differs from tin-lead to tin, with reduced finish thickness in the substitute part. These variations remain within the functional parameters of the BERGSTIK® series design.

For new designs or ongoing production requiring 36-position, 0.100" pitch right-angle headers with solder termination, the 75168-316-36LF is the appropriate selection. For legacy systems currently using the 75168-316-36, the 75168-316-36LF provides functional equivalence with improved regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Are the 75168-316-36 and 75168-316-36LF mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including mounting type (through-hole, right-angle), position count (36), pitch (0.100"), contact shape (square), and board-to-board style. They are mechanically interchangeable in applications designed for either part.

Q: What is the significance of the "LF" designation in the part number?

A: The "LF" suffix indicates lead-free compliance. The 75168-316-36LF is RoHS compliant with tin contact finish, whereas the original 75168-316-36 uses tin-lead finish and is RoHS non-compliant.

Q: Can the 75168-316-36LF be used as a direct replacement in existing assemblies?

A: The 75168-316-36LF is functionally equivalent and maintains all critical interface parameters. However, the change from tin-lead to tin contact finish and reduced finish thickness should be evaluated within the context of existing solder process specifications and thermal cycling requirements.

Q: What is the difference in contact finish thickness between these parts?

A: The 75168-316-36 features 150.0µin (3.81µm) tin-lead finish, while the 75168-316-36LF features 78.7µin (2.00µm) tin finish. Both finishes are suitable for solder termination applications within the BERGSTIK® series design envelope.

Q: Why is the original part classified as obsolete?

A: The 75168-316-36 is obsolete due to regulatory transition toward lead-free manufacturing standards. The 75168-316-36LF represents the current active production equivalent meeting modern RoHS compliance requirements.

Q: Are there packaging differences between these parts?

A: The 75168-316-36LF is supplied in bulk packaging. Packaging specifications for the original 75168-316-36 are not provided in the technical data.
