DF9B-41S-1V(22) Equivalent & Substitute Parts

Part Overview

The DF9B-41S-1V(22) is a 41-position rectangular connector receptacle manufactured by Hirose Electric Co Ltd, designed for surface mount applications with outer shroud contacts and tin contact finish. This component is classified as obsolete, which necessitates identification of active equivalent parts to ensure continued design support and procurement availability. The DF9B series maintains consistent electrical and mechanical specifications across compatible variants, enabling direct substitution where packaging and compliance requirements align.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF9B-41S-1V(22) is determined by strict equivalence across the following critical parameters:

• Connector Type & Series: Both parts belong to the DF9 series and maintain identical receptacle configuration with outer shroud contacts
• Electrical Specifications: Position count (41), pitch (1.00mm), and row configuration (2) are identical
• Mechanical Compatibility: Mated stacking height (4.3mm) and height above board (3.30mm) are preserved
• Contact Properties: Tin finish and solder retention features remain consistent
• Mounting Method: Surface mount technology is maintained across all variants

The primary distinction between the main part and its substitute relates to product status (obsolete vs. active), packaging format, RoHS compliance, and contact finish thickness specification. These differences do not affect electrical or mechanical interchangeability in circuit design.

Engineering Selection Recommendations

The DF9B-41S-1V(32) is the direct active equivalent for the obsolete DF9B-41S-1V(22). Selection of the substitute part is justified by the following factors:

• Product Status: The DF9B-41S-1V(32) maintains active status with Hirose Electric Co Ltd, ensuring ongoing availability and manufacturing support
• Electrical & Mechanical Equivalence: All functional parameters—position count, pitch, mounting configuration, and stacking dimensions—are identical
• Compliance Enhancement: The substitute part achieves RoHS compliance, addressing regulatory requirements that may apply to new designs or manufacturing revisions
• Packaging Availability: The DF9B-41S-1V(32) is supplied in Tape & Reel format, supporting automated assembly processes
• Contact Specification: The substitute includes documented contact finish thickness (1.00µm), providing additional specification clarity

No design modifications are required when transitioning from the main part to the substitute part. PCB footprints, mating connector specifications, and electrical performance remain unchanged.

Frequently Asked Questions (FAQ)

Q: Are the DF9B-41S-1V(22) and DF9B-41S-1V(32) electrically interchangeable?

A: Yes. Both parts are 41-position receptacles with identical pitch (1.00mm), row configuration (2), and contact finish (tin). Electrical performance and signal integrity characteristics are equivalent.

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

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. compliant), packaging format (unspecified vs. Tape & Reel), and contact finish thickness documentation (unspecified vs. 1.00µm). Functional specifications are identical.

Q: Can I use the DF9B-41S-1V(32) as a direct replacement on existing PCBs designed for the DF9B-41S-1V(22)?

A: Yes. The parts share identical mechanical dimensions, mounting type (surface mount), and stacking heights (4.3mm mated, 3.30mm above board). No PCB redesign is necessary.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance affects regulatory and supply chain considerations but does not impact electrical or mechanical interchangeability. The DF9B-41S-1V(32) is the preferred choice for applications subject to RoHS requirements.

Q: What packaging format should I specify for procurement?

A: The DF9B-41S-1V(32) is available in Tape & Reel (TR) format, which is standard for surface mount components and supports automated pick-and-place assembly.

Q: Are there any performance differences between tin contact finishes on these parts?

A: Both parts use tin contact finish. The DF9B-41S-1V(32) specifies a contact finish thickness of 1.00µm (39.4µin), providing documented thickness specification. Contact performance characteristics remain equivalent.
