Key Parameters

Substitute Part Grouping Explanation

Substitution for the 73993-101 is determined by strict equivalence across the following critical parameters:

• Number of positions: 36
• Pitch specification: 0.079" (2.00mm)
• Number of rows: 5
• Connector type: Header, Male Pins
• Mounting type: Through Hole
• Termination method: Press-Fit
• Contact layout: 30 Signal, 6 Ground
• Features: Shielded configuration
• Contact finish: Gold plating
• Current rating: 1A
• Operating temperature range: -55°C to 105°C
• Material flammability: UL94 V-0

The substitute part 73993-101LF maintains identical electrical and mechanical specifications while offering improved compliance status and active product availability.

Parameter Comparison

Engineering Selection Recommendations

The 73993-101LF serves as the direct functional equivalent to the obsolete 73993-101. Both parts maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, row configuration, contact layout, and thermal operating range.

The primary distinction between these parts is regulatory and availability status. The 73993-101LF is RoHS Compliant and carries Active product status, ensuring continued manufacturing support and supply chain availability. The original 73993-101 is RoHS non-compliant and obsolete, limiting future procurement options.

For new designs or system refreshes, the 73993-101LF is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, the 73993-101 remains functionally equivalent if inventory is available.

Frequently Asked Questions (FAQ)

Q: Are the 73993-101 and 73993-101LF mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including 36 positions, 0.079" (2.00mm) pitch, 5-row configuration, through-hole mounting, and press-fit termination. PCB footprints are identical.

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

A: The "LF" designation indicates Lead-Free composition, which aligns with RoHS compliance requirements. The 73993-101LF is RoHS Compliant, while the original 73993-101 is RoHS non-compliant.

Q: Can I use the 73993-101LF as a replacement in existing assemblies designed for the 73993-101?

A: Yes. The 73993-101LF is electrically and mechanically equivalent. No design modifications are required for substitution.

Q: What is the difference in packaging between these parts?

A: The 73993-101LF is supplied in Tube packaging. The original 73993-101 packaging specification is not provided in the technical data.

Q: Why is the 73993-101 classified as obsolete?

A: Obsolescence typically results from manufacturer discontinuation decisions. The availability of the RoHS-compliant 73993-101LF alternative reflects industry transition toward lead-free and compliant component standards.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical electrical specifications: 1A current rating, -55°C to 105°C operating temperature range, UL94 V-0 flammability rating, and gold contact finish at 30.0µin thickness.

Q: What is the contact layout configuration for these connectors?

A: Both parts feature 30 Signal pins and 6 Ground pins distributed across the 36-position shielded header in a 5-row configuration.
