DF1B-6P-2.5DS Equivalent & Substitute Parts

Part Overview

The DF1B-6P-2.5DS is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-cable/wire applications with 6 positions at 0.098" (2.50mm) pitch. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support, maintenance, and new production requirements. This reference provides direct equivalents and compatible alternatives based on electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution for the DF1B-6P-2.5DS is determined by the following critical parameters: connector type (header), contact type (male pin), number of positions (6), pitch specification, mounting configuration (through hole, right angle), shrouding style (4-wall), and termination method (solder). The substitute parts are grouped into two categories:

Direct Series Equivalents (Hirose DF1B Family): Parts DF1BZ-6P-2.5DS and DF1B-6P-2.5DS(01) maintain identical pitch (0.098" / 2.50mm), position count, mounting type, and shrouding. These are the primary equivalents within the same manufacturer series.

Cross-Manufacturer Alternatives (TE Connectivity AMPMODU): Parts 5-103361-4 and 5-104361-5 provide functional equivalence with a pitch variation to 0.100" (2.54mm). These alternatives share the same connector type, contact type, position count, mounting configuration, and shrouding specification, but operate at a different pitch standard. Cross-manufacturer substitution requires mechanical verification of mating interface compatibility.

Engineering Selection Recommendations

For Direct Replacement (Same Pitch 2.50mm):

DF1BZ-6P-2.5DS is the direct equivalent within the Hirose DF1B series with active product status. This part maintains identical pitch, position count, and mounting configuration. Note that the voltage rating is reduced to 150V compared to the original 250V specification. Selection of this part is appropriate when the application voltage requirement does not exceed 150V and RoHS3 compliance is required.

DF1B-6P-2.5DS(01) is the manufacturer-recommended replacement, offering active product status, RoHS3 compliance, and the original 250V voltage rating. The contact finish is upgraded to gold with reduced thickness (8.00µin / 0.203µm), providing improved corrosion resistance. This part is the preferred choice for direct substitution when voltage and compliance requirements match the original specification.

For Cross-Manufacturer Substitution (2.54mm Pitch):

5-103361-4 (TE Connectivity AMPMODU Mod II) and 5-104361-5 (TE Connectivity AMPMODU MTE) provide functional equivalence with a pitch change to 0.100" (2.54mm). Both parts are active, RoHS compliant, and feature gold-plated mating contacts. The 5-104361-5 includes board lock and keying slot features. Cross-manufacturer substitution requires verification that the mating connector interface accommodates the 2.54mm pitch standard and that mechanical clearances are compatible with the application.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-6P-2.5DS be used as a direct replacement for DF1B-6P-2.5DS?

A: DF1BZ-6P-2.5DS maintains identical pitch (2.50mm), position count (6), mounting type (through hole, right angle), and shrouding (4-wall). However, the voltage rating is reduced from 250V to 150V. Direct substitution is valid only if the application voltage requirement does not exceed 150V.

Q: What is the difference between DF1B-6P-2.5DS(01) and DF1BZ-6P-2.5DS?

A: Both are Hirose DF1B series parts with identical pitch and mechanical configuration. DF1B-6P-2.5DS(01) maintains the original 250V voltage rating and features gold-plated mating contacts (8.00µin thickness). DF1BZ-6P-2.5DS has a reduced 150V voltage rating and tin-plated mating contacts. Selection depends on voltage requirements and contact finish specifications.

Q: Can TE Connectivity parts 5-103361-4 or 5-104361-5 replace the Hirose DF1B-6P-2.5DS?

A: These TE Connectivity parts provide functional equivalence in connector type, contact type, position count, mounting configuration, and shrouding. However, the pitch differs: TE parts operate at 0.100" (2.54mm) versus the Hirose 2.50mm pitch. Cross-manufacturer substitution requires mechanical verification that the mating connector interface is compatible with the 2.54mm pitch standard and that PCB layout accommodates the dimensional change.

Q: What are the key differences between 5-103361-4 and 5-104361-5?

A: Both are TE Connectivity 6-position, right-angle headers at 2.54mm pitch with active product status and RoHS compliance. The 5-104361-5 includes board lock and keying slot features, while 5-103361-4 does not. Contact length specifications also differ: 5-104361-5 has 0.230" (5.84mm) mating contact length versus 0.240" (6.10mm) for 5-103361-4. Selection depends on whether board lock and keying features are required for the application.

Q: Are all substitute parts RoHS compliant?

A: The original DF1B-6P-2.5DS is RoHS non-compliant. All substitute parts listed (DF1BZ-6P-2.5DS, DF1B-6P-2.5DS(01), 5-103361-4, and 5-104361-5) are RoHS compliant or RoHS3 compliant, making them suitable for applications with RoHS requirements.

Q: What packaging options are available for these parts?

A: DF1B-6P-2.5DS is supplied in standard packaging (not specified). DF1BZ-6P-2.5DS is supplied in bulk packaging. DF1B-6P-2.5DS(01) is supplied in bulk packaging. TE Connectivity parts 5-103361-4 and 5-104361-5 are supplied in tube packaging. Packaging selection may affect lead times and minimum order quantities.
