Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF9B-9P-1V(22) is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 9 positions, 2 rows, 0.039" (1.00mm) pitch
• Mounting Technology: Surface mount with center strip contacts
• Contact Material: Tin plating
• Physical Dimensions: Mated stacking height of 4.3mm and height above board of 0.130" (3.30mm)
• Manufacturer Series: DF9 series by Hirose Electric Co Ltd

The substitute part DF9B-9P-1V(32) maintains identical electrical and mechanical specifications across all critical parameters, with the primary distinction being packaging format and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The DF9B-9P-1V(32) is the direct functional equivalent of the DF9B-9P-1V(22). Selection of the substitute part is based on the following engineering considerations:

Product Status: The DF9B-9P-1V(22) is obsolete, while the DF9B-9P-1V(32) maintains active status with Hirose Electric Co Ltd, ensuring continued availability and supply chain reliability.

Regulatory Compliance: The DF9B-9P-1V(32) is RoHS compliant, whereas the original part is RoHS non-compliant. This distinction is critical for applications subject to RoHS directives and environmental regulations.

Packaging Format: The substitute part is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes and high-volume production environments.

Electrical and Mechanical Equivalence: All functional parameters—connector configuration, pitch, mounting type, contact material, and physical dimensions—are identical between the two parts, ensuring direct interchangeability at the circuit board level.

Frequently Asked Questions (FAQ)

Q: Are the DF9B-9P-1V(22) and DF9B-9P-1V(32) electrically interchangeable?

A: Yes. Both parts are 9-position headers with identical pitch (0.039" / 1.00mm), mounting type (surface mount), connector configuration (center strip contacts), and contact finish (tin). They are electrically equivalent.

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

A: The primary differences are product status (obsolete vs. active), RoHS compliance status, and packaging format. The DF9B-9P-1V(32) is the active production variant supplied in Tape & Reel format, while the DF9B-9P-1V(22) is an obsolete variant.

Q: Can I use the DF9B-9P-1V(32) as a direct replacement in existing designs?

A: Yes, the DF9B-9P-1V(32) is a direct mechanical and electrical substitute. No circuit board layout modifications are required. The identical physical dimensions and pin configuration ensure drop-in compatibility.

Q: Does the packaging format affect component performance?

A: No. Tape & Reel (TR) packaging is a supply and handling format used for automated assembly. It does not affect the electrical or mechanical performance of the connector header itself.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance is a regulatory requirement in many markets and industries. The DF9B-9P-1V(32) meets RoHS standards, making it suitable for applications with environmental and regulatory compliance requirements, whereas the original part does not.

Q: Is the DF9B-9P-1V(32) available in the same quantities as the original part?

A: The DF9B-9P-1V(32) has significantly higher inventory availability (8717 Pcs) compared to the original part (780 Pcs), providing better supply chain security for production and procurement planning.
