Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF9B-41P-1V(20) is determined by strict equivalence across the following critical parameters:

• Number of positions: 41
• Pitch: 0.039" (1.00mm)
• Number of rows: 2
• Connector type: Header, Center Strip Contacts
• Mounting type: Surface Mount
• Contact finish: Tin
• Mated stacking height: 4.3mm
• Height above board: 0.130" (3.30mm)
• Series: DF9

The DF9B-41P-1V(32) meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement in new designs and procurement scenarios.

Parameter Comparison

Engineering Selection Recommendations

• Identical electrical and mechanical specifications across all functional parameters
• Active product status ensuring ongoing availability and supply chain continuity
• RoHS compliance, meeting current environmental and regulatory requirements
• Specified contact finish thickness of 39.4µin (1.00µm), providing documented plating specifications
• Tape & Reel packaging suitable for automated assembly processes

Frequently Asked Questions (FAQ)

Q: Can the DF9B-41P-1V(32) be used as a direct replacement for the DF9B-41P-1V(20)?

A: Yes. Both parts share identical electrical and mechanical specifications, including position count, pitch, row configuration, mounting type, and physical dimensions. The primary difference is product status and compliance certification.

Q: What is the significance of the packaging difference between these parts?

A: The DF9B-41P-1V(20) packaging is not specified, while the DF9B-41P-1V(32) is supplied in Tape & Reel format. Tape & Reel packaging is standard for automated surface mount assembly and does not affect component functionality or compatibility.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance indicates the part meets current environmental regulations for hazardous substance restrictions. The DF9B-41P-1V(32) RoHS compliance status makes it suitable for applications requiring regulatory adherence, whereas the obsolete DF9B-41P-1V(20) does not meet these standards.

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

A: No. Both parts maintain identical electrical characteristics, contact finish material (tin), and mated stacking height specifications.
