Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-8P-2.5DSA is determined by the following critical parameters:

Connector type, contact type, and pitch (0.098" / 2.50mm)
Number of positions (8) and row configuration (1 row)
Shrouding design (4-wall shrouded)
Mounting method (through-hole) and termination type (solder)
Fastening mechanism (push-pull)
Operating temperature range (-35°C ~ 85°C)
Voltage rating (250V)
Flammability rating (UL94 V-0)

The identified substitutes maintain all these core parameters. Variations in contact finish material and RoHS compliance status do not affect functional interchangeability in the connector interface.

Engineering Selection Recommendations

Both DF1BZ-8P-2.5DSA and DF1B-8P-2.5DSA(01) are active product alternatives to the obsolete DF1B-8P-2.5DSA. Selection between these substitutes is based on the following criteria:

DF1BZ-8P-2.5DSA is recommended for applications requiring ROHS3 compliance with tin contact finish. This part maintains the original electrical and mechanical specifications while offering improved regulatory compliance status and higher inventory availability (2000 pcs).

DF1B-8P-2.5DSA(01) is recommended for applications requiring enhanced contact reliability through gold plating. This part provides ROHS3 compliance with gold contact finish on the mating surface, offering superior corrosion resistance and contact durability. Inventory availability is 1150 pcs.

Both substitutes are electrically and mechanically interchangeable with the original part across all critical parameters including pitch, position count, shrouding, mounting, termination, operating temperature, and voltage rating.

Frequently Asked Questions (FAQ)

Q: Are DF1BZ-8P-2.5DSA and DF1B-8P-2.5DSA(01) directly interchangeable with DF1B-8P-2.5DSA?

A: Yes. Both substitutes maintain identical connector type, pitch (2.5mm), position count (8), shrouding design, mounting method, termination type, and fastening mechanism. All critical electrical and mechanical parameters are equivalent.

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

A: Contact finish is specified in the provided parameters. Tin finish is standard for general applications. Gold finish provides enhanced corrosion resistance and contact reliability in demanding environments. Selection depends on application requirements.

Q: Are there packaging differences between the substitutes?

A: DF1BZ-8P-2.5DSA is supplied in bulk packaging. DF1B-8P-2.5DSA(01) is supplied in bulk packaging. Packaging format does not affect connector functionality or compatibility.

Q: What is the significance of RoHS compliance status?

A: The original DF1B-8P-2.5DSA is RoHS non-compliant. Both substitutes (DF1BZ-8P-2.5DSA and DF1B-8P-2.5DSA(01)) are ROHS3 compliant, meeting current regulatory requirements for restricted substances in electrical and electronic equipment.

Q: Can I use these connectors interchangeably in existing designs?

A: Yes. The substitutes maintain all specified electrical and mechanical parameters. No design modifications are required for connector interface compatibility.
