Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF9B-31P-1V(31) is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 31 positions, 2 rows, 0.039" (1.00mm) pitch
• Connector Type: Header with center strip contacts
• Mounting Technology: Surface mount with solder retention
• Contact Specifications: Tin finish at 39.4µin (1.00µm) thickness
• Physical Dimensions: 4.3mm mated stacking height, 0.130" (3.30mm) height above board
• Environmental Classification: MSL 1 (Unlimited)
• Series Compatibility: DF9 series

The DF9B-31P-1V(32) meets all these criteria and is classified as an active product, making it a direct parametric equivalent suitable for replacement in new designs and procurement.

Parameter Comparison

Engineering Selection Recommendations

The DF9B-31P-1V(32) is the direct substitute for the obsolete DF9B-31P-1V(31). Selection of the substitute part is based on:

• Product Status: The DF9B-31P-1V(32) maintains active product status, ensuring long-term availability and manufacturing support.
• Regulatory Compliance: The substitute part is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
• Parametric Equivalence: All electrical and mechanical specifications are identical to the original part.
• Packaging Availability: The substitute is available in Tape & Reel (TR) packaging, suitable for automated assembly processes.

For applications currently using the DF9B-31P-1V(31), transition to the DF9B-31P-1V(32) is recommended for new production and design revisions.

Frequently Asked Questions (FAQ)

Q: Are the DF9B-31P-1V(31) and DF9B-31P-1V(32) electrically identical?

A: Yes. Both parts share identical electrical specifications including 31 positions, 0.039" (1.00mm) pitch, tin contact finish at 39.4µin (1.00µm) thickness, and MSL 1 rating.

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