DF1B-5P-2.5DS Equivalent & Substitute Parts

Part Overview

The DF1B-5P-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 5 positions at 0.098" (2.50mm) pitch. The part is currently obsolete, making substitute components necessary for new designs and ongoing production support. Equivalent and substitute parts are available from both Hirose and TE Connectivity, with varying compliance statuses and electrical specifications.

Substitute Part Grouping Explanation

Substitution for the DF1B-5P-2.5DS is determined by the following critical parameters: connector type (header), contact type (male pin), number of positions (5), pitch specification, mounting configuration (through hole, right angle), shrouding style (4 wall), termination method (solder), and fastening type (push-pull).

Group 1: Direct Hirose Equivalents maintain identical pitch (0.098" / 2.50mm), operating temperature range, and mechanical configuration. These parts differ in product status, RoHS compliance, and contact finish specifications.

Group 2: TE Connectivity Alternatives use a 0.100" (2.54mm) pitch instead of 0.098" (2.50mm). This pitch difference represents a mechanical incompatibility with the original connector cavity and mating interface, requiring board redesign or adapter solutions. These parts are from the AMPMODU Mod II series and feature different contact materials, operating temperature ranges, and current ratings.

Engineering Selection Recommendations

For Direct Replacement (Same Pitch - 0.098" / 2.50mm):

DF1BZ-5P-2.5DS is the primary active equivalent from Hirose. It maintains identical mechanical and electrical specifications with ROHS3 compliance. The voltage rating is reduced to 150V compared to the original 250V specification. Selection of this part requires verification that the 150V rating is acceptable for the application.

DF1B-5P-2.5DS(01) is the manufacturer-recommended active substitute from Hirose. It maintains the original 250V voltage rating and ROHS3 compliance. The contact finish is gold rather than tin, providing enhanced corrosion resistance. This part is preferred when the original voltage specification must be maintained.

For Alternative Pitch (0.100" / 2.54mm):

TE Connectivity parts (102203-2, 103361-3, 5-103361-3) operate at a different pitch and are not mechanically interchangeable without board redesign. These parts offer extended operating temperature range (-65°C to 105°C) and specified current rating (3A). Selection of TE Connectivity alternatives requires confirmation that the 2.54mm pitch is compatible with the application's connector cavity and mating interface.

5-103361-3 is the preferred TE Connectivity option, offering RoHS compliance and the highest inventory availability (4105 pcs).

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-5P-2.5DS be used as a direct replacement for DF1B-5P-2.5DS?

A: DF1BZ-5P-2.5DS maintains identical pitch (0.098" / 2.50mm), mounting configuration, and mechanical dimensions. The primary difference is the reduced voltage rating (150V vs. 250V). Direct substitution is possible if the application operates at or below 150V.

Q: What is the difference between DF1B-5P-2.5DS(01) and DF1BZ-5P-2.5DS?

A: Both are active Hirose equivalents with identical pitch and mechanical specifications. DF1B-5P-2.5DS(01) maintains the original 250V voltage rating with gold contact finish. DF1BZ-5P-2.5DS has a 150V voltage rating with tin contact finish. Selection depends on voltage requirements and contact finish preference.

Q: Why are TE Connectivity parts listed as alternatives if they use a different pitch?

A: TE Connectivity parts (102203-2, 103361-3, 5-103361-3) use 0.100" (2.54mm) pitch instead of 0.098" (2.50mm). These are not direct mechanical replacements and require board redesign or adapter solutions. They are listed as functional alternatives for applications where pitch modification is feasible.

Q: Are the TE Connectivity parts compatible with existing DF1B connector cavities?

A: No. The 0.100" (2.54mm) pitch of TE Connectivity AMPMODU Mod II connectors is incompatible with the 0.098" (2.50mm) cavity spacing of the DF1B series. Mechanical redesign is required for compatibility.

Q: Which substitute part has the best compliance status?

A: DF1B-5P-2.5DS(01) and DF1BZ-5P-2.5DS both offer ROHS3 compliance. Among TE Connectivity options, 5-103361-3 is RoHS compliant. Selection should be based on application voltage requirements and compliance mandates.

Q: What is the inventory status of these substitute parts?

A: DF1B-5P-2.5DS(01) has the highest inventory (2826 pcs), followed by DF1BZ-5P-2.5DS (1151 pcs) and 5-103361-3 (4105 pcs). Availability should be confirmed with the component supplier for production requirements.
