Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF9BA-41P-1V(32) is based on strict equivalence of the following critical parameters:

• Number of positions: 41
• Pitch: 0.039" (1.00mm)
• Number of rows: 2
• Connector type: Header, Center Strip Contacts
• Mounting type: Surface Mount
• Contact finish: Tin
• Contact finish thickness: 39.4µin (1.00µm)
• Features: Solder Retention
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part DF9B-41P-1V(32) maintains all these parameters identically. Minor variations in mated stacking height (4.5mm vs 4.3mm) and packaging format do not affect electrical or mechanical compatibility for standard applications.

Parameter Comparison

Engineering Selection Recommendations

The DF9B-41P-1V(32) is the direct substitute for the obsolete DF9BA-41P-1V(32). Selection of the substitute part is justified on the following basis:

• Electrical equivalence: All contact specifications, pitch, and position count are identical.
• Mechanical compatibility: Mounting footprint and height above board are identical; mated stacking height difference (0.2mm) is within standard tolerance ranges for connector applications.
• Product status: The substitute part maintains active product status with established supply chain availability.
• Compliance: The substitute part is RoHS Compliant, meeting current regulatory requirements.
• Packaging: The substitute is supplied in Tape & Reel format, standard for high-volume surface mount assembly.

Frequently Asked Questions (FAQ)

Q: Can DF9B-41P-1V(32) be used as a direct replacement for DF9BA-41P-1V(32)?

A: Yes. Both parts are electrically and mechanically equivalent. All critical parameters including position count, pitch, row configuration, contact finish, and mounting type are identical. The substitute part is the manufacturer-recommended equivalent.

Q: What is the significance of the mated stacking height difference?

A: The mated stacking height differs by 0.2mm (4.5mm vs 4.3mm). This variation is within standard connector tolerance ranges and does not affect PCB layout or mating compatibility for standard applications.

Q: Does the packaging format affect compatibility?

A: No. The packaging format (Tape & Reel for the substitute) is a supply and assembly consideration only. It does not affect the electrical or mechanical performance of the component itself.

Q: Is RoHS compliance a requirement for substitution?

A: The substitute part is RoHS Compliant. If RoHS compliance is required for your application, the substitute part meets this requirement. The original part's RoHS status was not specified.

Q: Are there any restrictions on using the substitute part?

A: No restrictions apply. The substitute part is functionally and mechanically equivalent and is the manufacturer-recommended alternative for the obsolete original part.
