Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-7P-2.5DS(01) is determined by the following critical parameters:

• Number of Positions: Must equal 7
• Connector Type: Must be Header
• Mounting Type: Must be Through Hole, Right Angle
• Shrouding: Must be Shrouded - 4 Wall
• Fastening Type: Must be Push-Pull
• Pitch - Mating: Tolerance range 0.098" (2.50mm) to 0.100" (2.54mm) acceptable for mechanical compatibility
• Contact Type: Must be Male Pin
• Termination: Must be Solder
• Style: Board to Cable/Wire or Board to Board

The substitute part 102203-4 meets these core criteria with a pitch variation of 0.100" (2.54mm), which represents a minor mechanical tolerance within acceptable substitution parameters for this connector category.

Engineering Selection Recommendations

DF1B-7P-2.5DS(01) is the primary selection for applications requiring RoHS compliance. This part maintains active production status and is RoHS compliant, making it suitable for regulated industries and modern manufacturing environments.

102203-4 serves as a substitute when RoHS compliance is not a requirement. This part is RoHS non-compliant and REACH affected, limiting its use in regulated applications. However, it offers an extended operating temperature range (-65°C ~ 105°C) compared to the primary part (-35°C ~ 85°C), and provides higher current rating (3A) where specified. The pitch variation of 0.100" (2.54mm) versus 0.098" (2.50mm) requires mechanical validation in the target application to ensure PCB footprint compatibility.

Both parts share identical electrical certifications (UL94 V-0, EAR99) and moisture sensitivity ratings, supporting functional equivalence in non-regulated applications.

Frequently Asked Questions (FAQ)

Q: Can 102203-4 be used as a direct replacement for DF1B-7P-2.5DS(01)?

A: Functional substitution is possible only when RoHS compliance is not mandated. The 0.002" (0.04mm) pitch difference requires verification that the PCB footprint accommodates the 2.54mm spacing. Mechanical fit must be validated before deployment.

Q: What is the significance of the pitch difference between these connectors?

A: The DF1B-7P-2.5DS(01) uses 2.50mm pitch while 102203-4 uses 2.54mm pitch. This 0.04mm difference affects PCB hole spacing and connector alignment. Substitution is only valid if the receiving PCB design accommodates the 2.54mm pitch specification.

Q: Why is RoHS compliance important for this selection?

A: RoHS compliance is mandatory for products sold in the European Union and many regulated markets. The DF1B-7P-2.5DS(01) is RoHS compliant, while 102203-4 is not. Selection depends on end-market regulatory requirements.

Q: What packaging differences exist between these parts?

A: DF1B-7P-2.5DS(01) is supplied in Bulk packaging with 884 units in stock. 102203-4 is supplied in Tube packaging with 2432 units in stock. Packaging affects handling, storage, and procurement logistics but does not impact electrical or mechanical function.

Q: Are the operating temperature ranges interchangeable?

A: No. DF1B-7P-2.5DS(01) operates from -35°C to 85°C, while 102203-4 operates from -65°C to 105°C. Selection must match the application's thermal requirements. The substitute part supports a wider temperature range but cannot be used if the primary part's narrower range is specified.

Q: What contact material differences affect performance?

A: DF1B-7P-2.5DS(01) uses Brass contacts with Gold finish (8.00µin thickness). 102203-4 uses Phosphor Bronze contacts with Gold mating finish (15.0µin thickness) and Tin-Lead post finish (100.0µin thickness). Both materials support the specified voltage and current ratings, with differences in contact durability and wear characteristics.
