Key Parameters

Substitute Part Grouping Explanation

The DF9B-23P-1V(32) qualifies as a direct substitute based on the following critical parameters:

• Connector Type & Configuration: Both parts are 23-position headers with center strip contacts in the DF9 series
• Electrical Interface: Identical pitch (0.039" / 1.00mm) and row configuration (2 rows) ensure mechanical and electrical compatibility
• Mounting Technology: Both utilize surface mount technology with identical board engagement heights
• Contact System: Tin-plated contacts with solder retention feature in both variants
• Physical Envelope: Matching mated stacking height (4.3mm) and height above board (0.130" / 3.30mm)

The primary distinction between these parts is product status and packaging format, not functional capability.

Parameter Comparison

Engineering Selection Recommendations

The DF9B-23P-1V(32) is the appropriate selection for new designs and procurement activities. This part maintains full electrical and mechanical compatibility with the obsolete DF9B-23P-1V(22) while offering the following advantages:

• Active Product Status: The substitute is currently in active production, ensuring long-term availability and supply chain stability
• RoHS Compliance: The DF9B-23P-1V(32) meets RoHS requirements, supporting regulatory compliance in applications subject to environmental directives
• Standard Packaging: Supplied in Tape & Reel format, facilitating automated assembly processes

For applications currently using DF9B-23P-1V(22), direct substitution with DF9B-23P-1V(32) requires no design modifications, PCB layout changes, or firmware updates. The connector footprint, pin assignment, and electrical characteristics remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can DF9B-23P-1V(32) be used as a direct replacement for DF9B-23P-1V(22) without PCB modifications?

A: Yes. Both parts share identical pitch (1.00mm), position count (23), row configuration (2), mounting type (surface mount), and physical envelope dimensions. No PCB layout changes are required.

Q: What is the significance of the different part number suffixes (22 vs. 32)?

A: The suffix indicates packaging and product status variants within the DF9B-23P-1V series. The (32) variant includes Tape & Reel packaging and active product status, while (22) represents an obsolete configuration.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or mechanical function. Both parts deliver identical electrical performance.

Q: Are there any compatibility concerns with existing mated connectors?

A: No. The identical pitch, contact configuration, and stacking height ensure full compatibility with existing mating connectors designed for the DF9 series.

Q: What inventory considerations apply to this substitution?

A: DF9B-23P-1V(22) is obsolete with limited remaining stock. DF9B-23P-1V(32) is in active production with standard availability through distribution channels, supporting both immediate and long-term procurement needs.
