Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF9B-25S-1V(20) is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle with outer shroud contacts, 25 positions, 2-row arrangement
• Electrical Specifications: 1.00mm pitch spacing, tin contact finish
• Mechanical Compatibility: Surface mount mounting type, 4.3mm mated stacking height, 3.30mm height above board
• Series Designation: DF9 base product family
• Contact Retention: Solder retention feature

The substitute part DF9B-25S-1V(32) maintains identical electrical and mechanical parameters across all critical dimensions and functional characteristics. The primary distinction is the packaging format and product status transition from obsolete to active manufacturing.

Parameter Comparison

Engineering Selection Recommendations

The DF9B-25S-1V(32) serves as the direct functional equivalent to the DF9B-25S-1V(20). Selection between these parts is determined by regulatory and procurement requirements:

DF9B-25S-1V(32) is the recommended selection for new designs and ongoing production due to:

• Active product status with continuous manufacturing support
• ROHS3 compliance, meeting current environmental regulations
• Tape & Reel packaging format suitable for automated assembly processes
• Equivalent electrical and mechanical specifications ensuring direct form-fit-function compatibility

DF9B-25S-1V(20) considerations apply only to legacy system maintenance where RoHS non-compliance is acceptable and obsolete component procurement is feasible.

Frequently Asked Questions (FAQ)

Q: Are DF9B-25S-1V(20) and DF9B-25S-1V(32) electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 25-position configuration, 1.00mm pitch, tin contact finish, and solder retention features. Electrical performance is equivalent.

Q: What is the difference between the part numbers?

A: The suffix designation (20 vs. 32) indicates packaging format and manufacturing revision. The DF9B-25S-1V(32) represents the current active production variant with updated RoHS compliance status.

Q: Can DF9B-25S-1V(32) be used as a direct replacement in existing PCB designs?

A: Yes. Mechanical dimensions, mounting footprint, and contact positioning are identical. No PCB redesign is required for substitution.

Q: What is the impact of RoHS3 compliance on part selection?

A: ROHS3 compliance is a regulatory requirement for products sold in the European Union and many other markets. DF9B-25S-1V(32) meets this requirement; DF9B-25S-1V(20) does not. Selection depends on applicable regulatory requirements for your application.

Q: Is the Tape & Reel packaging compatible with standard pick-and-place equipment?

A: Tape & Reel packaging is the standard format for automated surface mount assembly. DF9B-25S-1V(32) in TR packaging is compatible with conventional SMD assembly processes.

Q: What is MSL 1 rating significance?

A: MSL 1 (Unlimited) indicates no moisture sensitivity restrictions. Both parts can be stored and handled without special moisture control measures.
