Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-30DP-2.5DSA is determined by the following critical parameters that must remain constant across all equivalent parts:

Connector type (Header)
Contact type (Male Pin)
Number of positions (30)
Number of rows (2)
Pitch - mating (0.098" / 2.50mm)
Row spacing - mating (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)
Voltage rating (250V)
Material flammability rating (UL94 V-0)

The identified substitute parts maintain all these critical parameters. Variations in contact finish (tin versus gold plating), packaging format, RoHS compliance status, and product lifecycle status (active versus obsolete) do not affect functional interchangeability in the connector interface itself.

Engineering Selection Recommendations

For applications currently using the obsolete DF1B-30DP-2.5DSA, the following selection criteria apply:

DF1BZ-30DP-2.5DSA is a direct functional equivalent with active product status and RoHS compliance. This part maintains identical electrical and mechanical specifications with tin-plated mating contacts. Selection of this part is appropriate for new designs and ongoing production requiring RoHS-compliant components.

DF1B-30DP-2.5DSA(01) is the manufacturer-recommended substitute, also with active product status and RoHS compliance. This part differs only in contact finish specification, featuring gold-plated mating contacts with 8.00µin (0.203µm) thickness. Gold plating provides enhanced corrosion resistance and contact reliability in applications subject to environmental exposure or extended storage periods. This part is recommended for applications requiring superior contact durability or where gold-plated contacts are specified in design requirements.

Both substitute parts are functionally interchangeable with the original DF1B-30DP-2.5DSA at the connector interface level. Selection between DF1BZ-30DP-2.5DSA and DF1B-30DP-2.5DSA(01) depends on contact finish requirements and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-30DP-2.5DSA and DF1B-30DP-2.5DSA(01) be used interchangeably with the original DF1B-30DP-2.5DSA?

A: Yes. Both parts maintain identical connector interface specifications including pitch, number of positions, row configuration, mounting type, and fastening mechanism. The parts are mechanically and electrically interchangeable at the connector mating interface.

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

A: The DF1BZ-30DP-2.5DSA features tin-plated mating contacts, while the DF1B-30DP-2.5DSA(01) features gold-plated mating contacts with 8.00µin thickness. Gold plating provides enhanced corrosion resistance and is typically specified for applications requiring extended contact reliability or environmental durability.

Q: Does the packaging format affect connector compatibility?

A: No. The original DF1B-30DP-2.5DSA was supplied without specified packaging. The substitute parts DF1BZ-30DP-2.5DSA and DF1B-30DP-2.5DSA(01) are supplied in tray packaging. Packaging format does not affect the connector's electrical or mechanical performance in the application.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both DF1BZ-30DP-2.5DSA and DF1B-30DP-2.5DSA(01) are RoHS compliant. The original DF1B-30DP-2.5DSA is listed as RoHS non-compliant. For applications requiring RoHS compliance, either substitute part is appropriate.

Q: Which substitute part should be selected for new designs?

A: Selection depends on contact finish requirements. For standard applications, DF1BZ-30DP-2.5DSA with tin plating is suitable. For applications requiring enhanced contact durability or where gold-plated contacts are specified, DF1B-30DP-2.5DSA(01) is the appropriate selection.

Q: Are there any differences in operating temperature or voltage ratings?

A: No. All three parts maintain identical operating temperature range (-35°C ~ 85°C) and voltage rating (250V). Environmental performance specifications are equivalent across all parts.
