Key Parameters

Substitute Part Grouping Explanation

Substitution of the 71920-408 is determined by the following critical parameters that must remain constant:

• Connector Type & Style: Receptacle, Bottom or Top Entry, Board to Board configuration
• Number of Positions: 8 positions
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination Method: Solder
• Fastening Type: Push-Pull
• Insulation Material: Thermoplastic, Glass Filled
• Material Flammability Rating: UL94 V-0
• Contact Material: Phosphor Bronze
• Contact Shape: Square
• Physical Dimensions: Insulation Height 0.335" (8.51mm), Contact Length - Post 0.122" (3.10mm)

The primary difference between the main part and its substitute lies in the contact finish specification and product status. The 71920-408 uses Tin-Lead contact finish and is obsolete, while the substitute 71920-408LF uses Tin contact finish and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The 71920-408LF serves as the direct active equivalent to the obsolete 71920-408. Both connectors maintain identical mechanical and electrical interface specifications, ensuring pin-for-pin compatibility in board-to-board applications.

The 71920-408LF is RoHS Compliant, whereas the original 71920-408 is RoHS non-compliant. For new designs or applications subject to RoHS regulations, the 71920-408LF is the appropriate selection. The contact finish change from Tin-Lead to Tin reflects modern manufacturing standards and regulatory compliance requirements.

The 71920-408LF is classified as Active product status with established supply chain availability, making it suitable for both new production and legacy system support where component replacement is necessary.

Frequently Asked Questions (FAQ)

Q: Are the 71920-408 and 71920-408LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 8 positions, 0.100" (2.54mm) pitch, through-hole mounting, push-pull fastening, and physical dimensions. They are pin-for-pin compatible for board-to-board applications.

Q: What is the significance of the "LF" designation in the 71920-408LF part number?

A: The "LF" suffix indicates Lead-Free contact finish. The 71920-408LF uses Tin contact finish instead of the Tin-Lead finish found in the original 71920-408, aligning with RoHS compliance requirements.

Q: Can the 71920-408 be used in new designs?

A: The 71920-408 is classified as Obsolete. For new designs, the 71920-408LF is the recommended selection due to its Active product status, RoHS compliance, and established supply chain availability.

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

A: No electrical performance differences exist between the 71920-408 and 71920-408LF. Both maintain identical contact material (Phosphor Bronze), contact finish thickness (78.7µin / 2.00µm), and insulation specifications (UL94 V-0 rated thermoplastic, glass-filled material).

Q: What packaging options are available for the 71920-408LF?

A: The 71920-408LF is supplied in Tube packaging. The original 71920-408 packaging specification was not provided.

Q: Is the 71920-408LF suitable for automotive, industrial, and telecommunications applications?

A: Yes. The 71920-408LF is rated for Automotive, General Purpose, Industrial, and Telecommunications applications, maintaining the same application scope as the original 71920-408.
