Substitute Part Grouping Explanation

Substitution for the DF1B-8DP-2.5DSA is determined by strict equivalence across the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (8) and rows (2)
Pitch and row spacing (0.098" / 2.50mm)
Mounting type (Through Hole)
Termination method (Solder)
Fastening type (Push-Pull)
Shrouding configuration (Shrouded - 4 Wall)
Operating temperature range (-35°C ~ 85°C)

Engineering Selection Recommendations

Both DF1BZ-8DP-2.5DSA and DF1B-8DP-2.5DSA(01) are direct functional equivalents to the obsolete DF1B-8DP-2.5DSA. Selection between these substitutes is based on regulatory and compliance requirements:

DF1BZ-8DP-2.5DSA is the primary direct substitute, maintaining identical electrical and mechanical specifications with active product status and ROHS3 compliance. This part is suitable for applications requiring RoHS-compliant components with standard tin contact finish.

DF1B-8DP-2.5DSA(01) is the manufacturer-recommended substitute, offering ROHS3 compliance with enhanced contact finish specifications. The gold plating on mating contacts (8.00µin / 0.203µm thickness) provides improved corrosion resistance and contact reliability compared to tin finish. This variant is appropriate for applications requiring superior contact durability or operating in corrosive environments.

Both substitutes are available in active production with higher inventory levels than the obsolete main part, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-8DP-2.5DSA and DF1B-8DP-2.5DSA(01) be used interchangeably with DF1B-8DP-2.5DSA?

A: Yes. Both substitutes maintain full electrical and mechanical compatibility. The connector interface, pin configuration, pitch, mounting type, and electrical ratings are identical. The differences in contact finish and RoHS compliance do not affect functional interchangeability.

Q: What is the difference between tin and gold contact finishes?

A: The main part and DF1BZ-8DP-2.5DSA feature tin contact finish on mating surfaces. DF1B-8DP-2.5DSA(01) features gold plating (8.00µin thickness) on mating contacts, which provides enhanced corrosion resistance and improved contact reliability in demanding environments.

Q: Are there packaging differences between the substitutes?

A: The main part packaging is not specified. DF1BZ-8DP-2.5DSA is supplied in bulk packaging. DF1B-8DP-2.5DSA(01) is also supplied in bulk packaging. Packaging differences do not affect connector performance or compatibility.

Q: What is the significance of RoHS compliance status?

A: The main part is RoHS non-compliant. Both substitutes are ROHS3 compliant, meeting current regulatory requirements for restricted hazardous substances. For applications subject to RoHS regulations, either substitute is required.

Q: Are the operating temperature ranges identical?

A: Yes. All three parts operate across the same temperature range of -35°C to 85°C, ensuring thermal compatibility in equivalent applications.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying logistics and inventory management.
