Substitute Part Grouping Explanation

Substitution of the DF9B-41S-1V(20) is based on strict equivalence across the following critical parameters:

• Connector type and configuration (Receptacle, Outer Shroud Contacts)
• Electrical specifications (41 positions, 2 rows, 1.00mm pitch)
• Mechanical form factor (Surface mount, 4.3mm mated stacking height, 3.30mm height above board)
• Contact material and finish (Tin)
• Functional features (Solder Retention)

The identified substitute maintains identical electrical and mechanical compatibility while offering improved product status and regulatory compliance. Substitution is valid only when all parameters listed above are matched.

Parameter Comparison

Engineering Selection Recommendations

The DF9B-41S-1V(32) is the direct equivalent substitute for the obsolete DF9B-41S-1V(20). Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and form-factor compatibility.

The DF9B-41S-1V(32) offers the following advantages:

• Active product status with ongoing manufacturer support
• RoHS compliance, meeting current regulatory requirements
• Specified contact finish thickness (39.4µin / 1.00µm) for enhanced reliability documentation
• Tape & Reel packaging suitable for automated assembly processes
• Equivalent MSL rating and ECCN classification

Selection of the DF9B-41S-1V(32) eliminates obsolescence risk while maintaining full functional and mechanical compatibility with existing designs utilizing the DF9B-41S-1V(20).

Frequently Asked Questions (FAQ)

Q: Are the DF9B-41S-1V(20) and DF9B-41S-1V(32) electrically interchangeable?

A: Yes. Both parts are 41-position receptacles with identical pitch (1.00mm), row configuration (2 rows), contact finish (tin), and electrical ratings. They are electrically equivalent.

Q: Will the DF9B-41S-1V(32) fit the same PCB footprint as the DF9B-41S-1V(20)?

A: Yes. Both parts have identical mounting type (surface mount), mated stacking height (4.3mm), and height above board (3.30mm). PCB footprints are mechanically compatible.

Q: What is the significance of the different packaging between these parts?

A: The DF9B-41S-1V(20) has unspecified packaging, while the DF9B-41S-1V(32) is supplied in Tape & Reel format. Tape & Reel packaging is standard for automated assembly and provides better handling and storage characteristics for high-volume production.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a regulatory and environmental classification that does not affect electrical or mechanical compatibility. The DF9B-41S-1V(32) meets current RoHS requirements, making it preferable for new designs and applications subject to RoHS regulations.

Q: Are there any restrictions on substituting the DF9B-41S-1V(20) with the DF9B-41S-1V(32)?

A: No restrictions exist based on the provided specifications. Both parts are from the same manufacturer, same series, and share all critical electrical and mechanical parameters. Substitution is valid for all applications where the original part was specified.
