Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF9BA-41P-1V(69) is determined by the following critical parameters:

• Number of Positions: Must be 41
• Pitch: Must be 0.039" (1.00mm)
• Number of Rows: Must be 2
• Mounting Type: Must be Surface Mount
• Contact Finish: Must be Gold
• Connector Type: Must be Header, Center Strip Contacts
• Series: DF9 family compatibility

The primary substitute part DF9B-41P-1V(69) maintains all critical electrical and mechanical parameters while offering active product status and improved availability. This part represents a direct functional equivalent with identical pin configuration, pitch spacing, and contact specifications.

Parameter Comparison

Engineering Selection Recommendations

The DF9B-41P-1V(69) is the primary substitute for the obsolete DF9BA-41P-1V(69). This substitution is supported by:

• Identical electrical specifications and pin configuration
• Matching mechanical dimensions and mounting requirements
• Active product status with confirmed inventory availability
• RoHS compliance certification for the substitute part
• Equivalent moisture sensitivity rating
• Minimal variation in mated stacking height (0.2mm difference)

The transition from DF9BA to DF9B represents a product line evolution within the DF9 series, maintaining full compatibility for applications requiring 41-position surface mount headers with 1.00mm pitch and gold-plated contacts.

Frequently Asked Questions (FAQ)

Q: Can DF9B-41P-1V(69) be used as a direct replacement for DF9BA-41P-1V(69)?

A: Yes. Both parts share identical pin counts, pitch spacing, row configuration, and contact specifications. The primary difference is product status and RoHS compliance of the substitute.

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

A: The DF9BA-41P-1V(69) has a 4.5mm mated stacking height while the DF9B-41P-1V(69) has 4.3mm. This 0.2mm variation is within typical mechanical tolerances for connector applications and does not affect functional compatibility in standard PCB assembly processes.

Q: Does the RoHS compliance of DF9B-41P-1V(69) affect compatibility?

A: RoHS compliance is an environmental and regulatory attribute that does not impact electrical or mechanical compatibility. The substitute part meets or exceeds the specifications of the original part.

Q: Are there packaging differences between these parts?

A: The DF9BA-41P-1V(69) packaging is not specified in available data. The DF9B-41P-1V(69) is supplied in Tape & Reel (TR) format, which is standard for surface mount components and facilitates automated assembly processes.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
