Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50006-1183C is determined by strict equivalence across the following critical parameters:

• Position Count and Layout: 183 positions in a 3-row × 61-column configuration
• Pitch Specification: 0.100" (2.54mm) center-to-center spacing
• Connector Type and Gender: Header with male pins
• Mounting and Termination: Through-hole press-fit installation
• Contact System: Gold-plated finish at 30.0µin thickness
• Mechanical Housing: Black color, UL94 V-0 rated material with mating guide
• Series Compatibility: HPC™ series designation

The substitute part 50006-1183CLF maintains identical electrical and mechanical specifications across all these parameters, with the primary distinction being product status and RoHS compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The 50006-1183CLF is the direct functional equivalent of the 50006-1183C. Both parts share identical electrical and mechanical specifications, including position count, pitch, contact system, and housing material properties. The primary differentiators are product lifecycle status and regulatory compliance:

• 50006-1183C: Obsolete status with RoHS non-compliant classification. Suitable only for legacy system maintenance where original part specifications are mandated.
• 50006-1183CLF: Active product status with RoHS compliance. Recommended for new designs and ongoing production applications requiring current component availability and regulatory alignment.

For applications where RoHS compliance is a requirement or where long-term component availability is critical, the 50006-1183CLF is the appropriate selection. Both parts are mechanically and electrically interchangeable within daughtercard backplane applications.

Frequently Asked Questions (FAQ)

Q: Are the 50006-1183C and 50006-1183CLF mechanically interchangeable?

A: Yes. Both parts feature identical position counts (183), pitch spacing (0.100"), row/column configuration (3×61), mounting type (through-hole), and termination method (press-fit). They are direct mechanical substitutes.

Q: What is the difference between these two part numbers?

A: The 50006-1183CLF is the active production variant with RoHS compliance. The 50006-1183C is the obsolete predecessor with RoHS non-compliant classification. All electrical and mechanical parameters are identical.

Q: Can I use the 50006-1183CLF in place of the 50006-1183C in existing designs?

A: Yes. The 50006-1183CLF maintains full compatibility with applications designed for the 50006-1183C. No design modifications are required.

Q: Why does the part number include "LF" in the suffix?

A: The "LF" designation indicates lead-free and RoHS-compliant manufacturing, distinguishing it from the earlier non-compliant variant.

Q: Are there any differences in contact finish or plating specifications?

A: No. Both parts feature gold-plated contacts with identical finish thickness of 30.0µin (0.76µm).

Q: What is the current availability status of each part?

A: The 50006-1183C is obsolete with limited remaining inventory. The 50006-1183CLF is in active production with current availability.
