DF1BZ-7P-2.5DS Equivalent & Substitute Parts

Part Overview

The DF1BZ-7P-2.5DS is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-cable/wire applications. This 7-position connector operates at 0.098" (2.50mm) pitch with shrouded 4-wall construction and push-pull fastening. The part is currently active in production with 1107 units in stock. Substitute parts are identified to address inventory availability, lead time requirements, or specific application constraints while maintaining functional compatibility within defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1BZ-7P-2.5DS is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pin contacts
• Position Count & Row Configuration: 7 positions in single row
• Mounting & Orientation: Through-hole, right-angle mounting
• Shrouding & Fastening: Shrouded 4-wall construction with push-pull fastening
• Termination Method: Solder termination
• Electrical Ratings: Voltage rating of 150V minimum; operating temperature range compatibility
• Compliance: UL94 V-0 flammability rating; RoHS compliance status

The identified substitute part 102203-4 (TE Connectivity AMP Connectors) shares the core functional architecture: 7-position header with male pins, through-hole right-angle mounting, shrouded 4-wall design, push-pull fastening, and solder termination. However, this substitute operates at 0.100" (2.54mm) pitch, which represents a mechanical deviation from the primary specification. This pitch difference requires mechanical validation for PCB layout compatibility and mating interface clearance before deployment.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (DF1BZ-7P-2.5DS): Recommended for new designs and applications requiring ROHS3 compliance. This part maintains active production status with adequate inventory (1107 units). The 2.50mm pitch specification is fixed and must be accommodated in PCB layout design.

Substitute Part (102203-4): Applicable only when the following conditions are met:

• PCB layout can accommodate 0.100" (2.54mm) pitch spacing without redesign
• RoHS non-compliance is acceptable for the application
• Operating temperature range of -65°C to 105°C meets or exceeds application requirements
• Mating interface compatibility with 2.54mm pitch connectors is confirmed

The pitch differential (2.50mm vs. 2.54mm) represents a 1.6% spacing increase. This mechanical deviation requires validation against PCB trace routing, component placement, and connector mating interface specifications before substitution is implemented.

Frequently Asked Questions (FAQ)

Q: Can the 102203-4 substitute directly for the DF1BZ-7P-2.5DS without PCB modification?

A: No. The pitch difference (2.50mm vs. 2.54mm) requires PCB layout verification. Direct substitution without mechanical validation may result in misalignment or contact failure.

Q: What is the primary difference between these two connectors?

A: The mating pitch differs: DF1BZ-7P-2.5DS operates at 0.098" (2.50mm), while 102203-4 operates at 0.100" (2.54mm). Both share identical connector architecture (7-position header, male pins, through-hole right-angle, shrouded 4-wall, push-pull fastening, solder termination).

Q: Does the 102203-4 meet RoHS requirements?

A: No. The 102203-4 is RoHS non-compliant, whereas the DF1BZ-7P-2.5DS is ROHS3 compliant. Applications requiring RoHS certification must use the primary part.

Q: Are the operating temperature ranges compatible?

A: The DF1BZ-7P-2.5DS operates from -35°C to 85°C. The 102203-4 operates from -65°C to 105°C, providing a wider temperature envelope. For applications within the -35°C to 85°C range, both parts are functionally equivalent from a thermal perspective.

Q: What packaging formats are available?

A: DF1BZ-7P-2.5DS is supplied in Bulk packaging (1107 units in stock). The 102203-4 is supplied in Tube packaging (2432 units in stock). Packaging format may affect handling, storage, and assembly line integration.

Q: Are the contact materials the same?

A: No. DF1BZ-7P-2.5DS uses Brass contacts with Tin finish. The 102203-4 uses Phosphor Bronze contacts with Gold mating finish and Tin-Lead post finish. Contact material differences may affect electrical conductivity and corrosion resistance characteristics.
