Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50006-1144A is determined by strict equivalence across the following critical parameters:

• Electrical Configuration: 144 positions, 3 rows × 48 columns
• Mechanical Compatibility: 0.100" (2.54mm) pitch, through-hole press-fit termination
• Physical Characteristics: Black color, mating guide feature
• Contact Properties: Gold finish at 30.0µin (0.76µm) thickness
• Regulatory Compliance: UL94 V-0 flammability rating
• Connector Classification: High-density header, male pins, daughtercard application

The substitute part 50006-1144ALF maintains identical electrical and mechanical specifications while differing in product status and RoHS compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The 50006-1144ALF serves as the direct functional equivalent to the obsolete 50006-1144A. Both components share identical electrical and mechanical specifications, including position count, pitch, termination method, and contact properties. The primary distinction lies in product lifecycle status and regulatory compliance.

The 50006-1144ALF is classified as active product status, ensuring continued manufacturer support and availability. Additionally, the 50006-1144ALF meets RoHS compliance requirements, whereas the original 50006-1144A does not. For new designs or system refreshes, the 50006-1144ALF is the appropriate selection. For legacy system maintenance requiring the exact original specification, the 50006-1144A remains available in current inventory (944 pieces).

Frequently Asked Questions (FAQ)

Q: Are the 50006-1144A and 50006-1144ALF mechanically interchangeable?

A: Yes. Both components feature identical pitch (0.100"), position count (144), row/column configuration (3×48), mounting type (through-hole), and termination method (press-fit). Physical dimensions and mating interfaces are equivalent.

Q: What is the significance of the "LF" suffix in the part number 50006-1144ALF?

A: The "LF" designation indicates lead-free and RoHS-compliant manufacturing. This reflects the component's compliance with environmental and hazardous substance restrictions.

Q: Can the 50006-1144ALF be used in applications originally designed for the 50006-1144A?

A: Yes. The electrical and mechanical specifications are identical. The 50006-1144ALF is a direct substitute for the obsolete 50006-1144A in all daughtercard backplane applications requiring 144-position high-density headers with press-fit termination.

Q: Are there any differences in contact reliability or performance between these parts?

A: No. Both components feature gold contact finish at 30.0µin (0.76µm) thickness and UL94 V-0 flammability rating. Contact performance and reliability characteristics are equivalent.

Q: What inventory considerations should be evaluated?

A: The 50006-1144A has 944 pieces in stock (obsolete status). The 50006-1144ALF has 778 pieces in stock (active status). For long-term supply chain planning, the active-status 50006-1144ALF is recommended.
