Substitute Part Grouping Explanation

Substitution of the DF9B-41P-1V(22) with the DF9B-41P-1V(32) is based on strict equivalence of the following critical parameters:

• Connector Type & Series: Both parts belong to the DF9 series and are header connectors with center strip contacts
• Electrical Configuration: Identical 41-position, 2-row arrangement with 0.039" (1.00mm) pitch
• Mechanical Compatibility: Matching mated stacking height (4.3mm) and height above board (0.130" / 3.30mm)
• Contact Properties: Both feature tin plating and solder retention capability
• Mounting Method: Both are surface mount components
• Base Product Number: Both share the DF9B base designation

The primary difference between these parts is the packaging format and product status. The DF9B-41P-1V(32) is supplied in Tape & Reel (TR) packaging and maintains active product status with RoHS compliance, whereas the DF9B-41P-1V(22) is obsolete and non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The DF9B-41P-1V(32) is the direct functional equivalent for the obsolete DF9B-41P-1V(22). Selection of the substitute part is justified on the following grounds:

• Product Lifecycle: The DF9B-41P-1V(32) maintains active status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The substitute part is RoHS compliant, meeting current environmental and regulatory requirements
• Electrical & Mechanical Equivalence: All critical parameters—position count, pitch, row configuration, stacking height, and contact properties—are identical
• Packaging Consideration: The Tape & Reel packaging of the substitute part is standard for automated assembly processes and does not affect functional compatibility

No additional design modifications are required when transitioning from the DF9B-41P-1V(22) to the DF9B-41P-1V(32).

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts feature 41 positions arranged in 2 rows with 0.039" (1.00mm) pitch, tin-plated contacts, and solder retention. Electrical performance and signal integrity characteristics are equivalent.

Q: What is the difference between the part numbers?

A: The suffix designation (22 vs. 32) indicates the packaging format. The DF9B-41P-1V(22) is supplied in bulk packaging, while the DF9B-41P-1V(32) is supplied in Tape & Reel (TR) format. The TR packaging is optimized for automated pick-and-place assembly.

Q: Can the DF9B-41P-1V(32) be used as a direct replacement on existing PCBs designed for the DF9B-41P-1V(22)?

A: Yes. The footprint, mounting type, and all mechanical dimensions are identical. No PCB redesign is required.

Q: Why is the DF9B-41P-1V(22) marked as obsolete?

A: The DF9B-41P-1V(22) is no longer in active production. The DF9B-41P-1V(32) represents the current active equivalent in the DF9 series product line.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a regulatory and environmental attribute that does not affect electrical or mechanical compatibility. The substitute part's RoHS compliance status makes it preferable for new designs and applications subject to environmental regulations.

Q: Are there any height or footprint differences between these parts?

A: No. Both parts have identical mated stacking height (4.3mm) and height above board (0.130" / 3.30mm). PCB footprints are identical.
