DF1B-11P-2.5DS(01) Equivalent & Substitute Parts

Part Overview

The DF1B-11P-2.5DS(01) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-cable/wire applications. This 11-position connector operates at 250V with a 0.098" (2.50mm) pitch and features shrouded 4-wall construction with push-pull fastening. The product is currently in Last Time Buy status, making identification of equivalent alternatives essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF1B-11P-2.5DS(01) is limited by the following critical parameters:

• Pitch Tolerance: The 0.098" (2.50mm) mating pitch is a primary constraint. The identified substitute, 5-102203-8, operates at 0.100" (2.54mm) pitch, representing a 0.02mm difference. This pitch variance requires mechanical verification for PCB footprint compatibility.
• Number of Positions: Both parts maintain 11 positions in a single row, ensuring pin count equivalence.
• Connector Configuration: Both are shrouded 4-wall headers with male pins, through-hole mounting, and right-angle orientation.
• Electrical Ratings: The main part specifies 250V; the substitute does not declare a voltage rating in the provided data. The substitute specifies 3A current rating, which the main part does not provide.
• Termination & Fastening: Both use solder termination and push-pull fastening.
• Compliance: Both are RoHS compliant and carry UL94 V-0 flammability ratings.

The primary substitution consideration is the pitch difference (2.50mm vs. 2.54mm), which may require PCB redesign or mechanical adaptation.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration - Pitch Incompatibility: The 0.02mm pitch difference between the DF1B-11P-2.5DS(01) (2.50mm) and 5-102203-8 (2.54mm) represents a material mechanical variance. Direct PCB footprint substitution is not feasible without redesign. This difference must be evaluated against application-specific tolerance requirements.

Product Status: The DF1B-11P-2.5DS(01) is in Last Time Buy status, indicating limited future availability. The 5-102203-8 is Active, providing long-term procurement stability.

Compliance & Certifications: Both parts meet RoHS requirements and UL94 V-0 flammability standards. The substitute carries ROHS3 compliance, representing current regulatory alignment.

Electrical & Thermal Performance: The substitute offers an extended operating temperature range (-65°C to 105°C versus -35°C to 85°C) and specifies 3A current rating. The main part specifies 250V; the substitute voltage rating is not provided in the available data. Electrical compatibility must be confirmed through application requirements.

Material Differences: Contact material differs (Brass vs. Phosphor Bronze) and gold plating thickness varies (8.00µin vs. 15.0µin). These differences may affect contact resistance and durability characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 5-102203-8 be used as a direct replacement for the DF1B-11P-2.5DS(01)?

A: Direct substitution is not possible due to pitch incompatibility. The DF1B-11P-2.5DS(01) operates at 2.50mm pitch while the 5-102203-8 operates at 2.54mm pitch. PCB footprint redesign is required for mechanical compatibility.

Q: What is the significance of the pitch difference?

A: A 0.02mm pitch variance affects PCB hole spacing and connector alignment. Existing PCB designs cannot accommodate this substitute without layout modification and re-fabrication.

Q: Are the electrical ratings compatible?

A: The main part specifies 250V operation. The substitute does not provide a voltage rating in the available technical data. The substitute specifies 3A current capability. Electrical compatibility must be confirmed against application requirements before selection.

Q: Why is the DF1B-11P-2.5DS(01) in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this product. Existing inventory is available, but future procurement will not be possible. Alternative sourcing strategies should be implemented.

Q: What are the packaging differences?

A: The DF1B-11P-2.5DS(01) is supplied in Bulk packaging, while the 5-102203-8 is supplied in Tube packaging. This affects handling, storage, and component management procedures.

Q: How do the contact materials affect performance?

A: The DF1B-11P-2.5DS(01) uses Brass contacts with 8.00µin gold plating. The 5-102203-8 uses Phosphor Bronze contacts with 15.0µin gold plating. Phosphor Bronze offers improved spring characteristics and durability; thicker gold plating provides enhanced corrosion resistance. Material selection depends on application environmental conditions and contact cycling requirements.

Q: What is the operating temperature range difference?

A: The DF1B-11P-2.5DS(01) operates from -35°C to 85°C. The 5-102203-8 operates from -65°C to 105°C. The substitute provides extended thermal capability, suitable for wider environmental applications.
