Key Parameters

Substitute Part Grouping Explanation

The DF9-25P-1V(32) qualifies as a direct substitute based on the following critical parameters that determine functional and mechanical compatibility:

• Connector Type & Configuration: Both parts are 25-position headers with center strip contacts in a 2-row arrangement
• Electrical Interface: Identical pitch of 0.039" (1.00mm) ensures PCB footprint compatibility
• Mounting Technology: Both utilize surface mount assembly methods
• Physical Envelope: Matching height above board (0.130" / 3.30mm) and mated stacking heights (4.3mm) confirm mechanical interchangeability
• Contact Material: Tin finish on both parts maintains consistent solderability and electrical properties
• Mechanical Features: Both incorporate board guide and solder retention features

The substitution is based solely on these electrical and mechanical parameters. The primary distinction is product status and compliance certification, not functional capability.

Engineering Selection Recommendations

The DF9-25P-1V(32) is the appropriate selection for applications currently specified with DF9-25P-1V(20) connectors. This substitution is supported by:

• Functional Equivalence: Identical electrical and mechanical parameters ensure direct PCB compatibility without design modification
• Product Lifecycle: The DF9-25P-1V(32) maintains active product status, ensuring long-term availability and supply chain stability
• Regulatory Compliance: The substitute achieves ROHS3 compliance, addressing modern regulatory requirements that the obsolete variant does not meet
• Certification Alignment: Both parts share identical REACH and ECCN classifications, maintaining consistent compliance documentation

No design changes are required for this substitution. The parts are mechanically and electrically interchangeable at the PCB level.

Frequently Asked Questions (FAQ)

Q: Can DF9-25P-1V(32) be used as a direct replacement for DF9-25P-1V(20) without PCB modification?

A: Yes. The parts share identical pitch (0.039" / 1.00mm), position count (25), row configuration (2), and mounting height specifications. PCB footprints are fully compatible.

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

A: The DF9-25P-1V(20) is obsolete, while the DF9-25P-1V(32) is active. Additionally, the DF9-25P-1V(32) achieves ROHS3 compliance, whereas the DF9-25P-1V(20) is non-compliant. The suffix notation (20 vs 32) reflects packaging and compliance variants within the same base product series DF9-25P.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts feature identical contact finish (tin), connector type (header with center strip contacts), and mechanical features (board guide, solder retention). Electrical performance is equivalent.

Q: What packaging is available for the substitute part?

A: The DF9-25P-1V(32) is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Does the contact finish thickness differ between the two parts?

A: The DF9-25P-1V(20) does not specify contact finish thickness. The DF9-25P-1V(32) specifies 39.4µin (1.00µm) tin finish thickness, providing documented coating specification for the active variant.
