DF1B-11P-2.5DS Equivalent & Substitute Parts

Part Overview

The DF1B-11P-2.5DS is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-cable applications with 11 positions at 2.50mm pitch. This connector features shrouded 4-wall construction with push-pull fastening and solder termination. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance, repair, and legacy design support.

Substitute Part Grouping Explanation

Substitution of the DF1B-11P-2.5DS is determined by the following critical parameters:

Connector Type & Contact Configuration: Header with male pins for board-to-cable connectivity
Position Count: 11 positions maintained across substitute options
Mounting & Orientation: Through-hole, right-angle mounting required
Shrouding & Fastening: 4-wall shrouded construction with push-pull fastening mechanism
Termination Method: Solder termination for PCB integration
Pitch Tolerance: Mating pitch of 2.50mm (0.098") is the primary mechanical constraint

The substitute part 5-102203-8 (TE Connectivity AMP Connectors) maintains functional equivalence through identical connector type, position count, mounting configuration, shrouding design, and fastening mechanism. While pitch differs slightly (2.54mm vs 2.50mm), this represents a standard industry alternative within the rectangular connector header category for equivalent applications.

Engineering Selection Recommendations

The DF1B-11P-2.5DS is classified as obsolete, necessitating substitute part identification for procurement and design continuity. The 5-102203-8 from TE Connectivity AMP Connectors series (AMPMODU Mod II) is the manufacturer-recommended substitute.

Product Status Consideration: The substitute part maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete original.

Compliance & Certification: The substitute part achieves ROHS3 compliance, whereas the original is RoHS non-compliant. Both parts maintain UL94 V-0 flammability rating. Selection should account for regulatory requirements of the target application and end-use market.

Operating Temperature Range: The substitute part extends the operating temperature range to -65°C ~ 105°C, providing broader environmental capability than the original specification of -35°C ~ 85°C.

Mechanical & Electrical Compatibility: Both connectors maintain identical connector type, position count, mounting configuration, shrouding design, and fastening mechanism. The pitch difference (2.50mm vs 2.54mm) represents a standard industry tolerance variation for rectangular connector headers in this category.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the DF1B-11P-2.5DS?

A: The DF1B-11P-2.5DS is obsolete. The 5-102203-8 is the manufacturer-recommended substitute, offering active production status and improved compliance characteristics.

Q: Are the pitch specifications interchangeable?

A: The original part uses 2.50mm (0.098") pitch, while the substitute uses 2.54mm (0.100") pitch. This represents a standard industry variation for rectangular connector headers. PCB footprint design must accommodate the substitute pitch specification.

Q: What are the key mechanical compatibility factors?

A: Both connectors share identical connector type (header), contact configuration (male pin), position count (11), mounting method (through-hole, right-angle), shrouding design (4-wall), and fastening mechanism (push-pull). These parameters ensure functional equivalence in board-to-cable applications.

Q: Does the substitute part meet current regulatory requirements?

A: The 5-102203-8 achieves ROHS3 compliance, whereas the original DF1B-11P-2.5DS is RoHS non-compliant. Applications subject to RoHS regulations should specify the substitute part.

Q: What is the packaging difference?

A: The original part packaging is not specified. The substitute part 5-102203-8 is supplied in tube packaging.

Q: Are there differences in contact materials?

A: The original uses brass contacts with tin finish. The substitute uses phosphor bronze contacts with gold mating finish (15.0µin) and tin post finish (100.0µin). These material differences support the substitute's enhanced performance characteristics.

Q: What is the current rating specification?

A: The original part does not specify current rating. The substitute part 5-102203-8 is rated for 3A continuous current.
