2600-04-R Equivalent & Substitute Parts

Part Overview

The 2600-04-R is a rectangular connector header manufactured by On Shore Technology Inc., designed for through-hole, right-angle board-to-cable/wire applications. This connector features 4 positions with 0.100" (2.54mm) pitch spacing, solder termination, and friction lock fastening. The part is currently active in production with full inventory availability (819 pcs in stock). Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, supply chain alternatives, or specific application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2600-04-R is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pin contacts
• Position Count & Row Configuration: 4 positions, single row
• Pitch Spacing: 0.100" (2.54mm) mating pitch
• Mounting & Orientation: Through hole, right-angle mounting
• Termination Method: Solder termination
• Electrical Ratings: Minimum 250V voltage rating and 3A current capacity
• Environmental Compliance: UL94 V-0 flammability rating and ROHS3 compliance

The identified substitute DF1B-4P-2.5DS(01) meets the core functional requirements of header-type, 4-position, single-row, through-hole, right-angle, solder-terminated rectangular connectors with equivalent electrical ratings and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 2600-04-R and DF1B-4P-2.5DS(01) are active production parts with ROHS3 compliance and UL94 V-0 flammability certification, meeting standard regulatory requirements for rectangular connector applications.

The 2600-04-R operates across a wider temperature range (-55°C to 105°C) compared to the DF1B-4P-2.5DS(01) (-35°C to 85°C). Selection should account for application-specific thermal requirements.

The DF1B-4P-2.5DS(01) features enhanced shrouding (4-wall configuration versus 1-wall) and gold-plated mating contacts, which may provide improved durability and contact reliability in specific environments. The push-pull fastening mechanism differs from the friction lock design of the 2600-04-R.

Pitch spacing differs by 0.002" (0.04mm), which may require PCB layout verification for mechanical compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the DF1B-4P-2.5DS(01) directly replace the 2600-04-R in existing designs?

A: Direct mechanical and electrical compatibility requires verification of PCB pad spacing. The 2600-04-R uses 0.100" (2.54mm) pitch, while the DF1B-4P-2.5DS(01) uses 0.098" (2.50mm) pitch. This 0.002" difference may affect board layout fit. Electrical ratings (250V, 3A minimum) are equivalent.

Q: What are the key differences in connector design between these parts?

A: The 2600-04-R uses friction lock fastening with 1-wall shrouding and tin-plated contacts. The DF1B-4P-2.5DS(01) uses push-pull fastening with 4-wall shrouding and gold-plated contacts. Both are solder-terminated, through-hole, right-angle headers with 4 positions in a single row.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 2600-04-R and DF1B-4P-2.5DS(01) are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: Which part is suitable for extended temperature applications?

A: The 2600-04-R supports -55°C to 105°C operation, providing a wider temperature range than the DF1B-4P-2.5DS(01) (-35°C to 85°C). For applications requiring extended low-temperature performance, the 2600-04-R is the appropriate selection.

Q: What is the significance of contact finish differences?

A: The 2600-04-R features tin-plated mating contacts (120.0µin thickness), while the DF1B-4P-2.5DS(01) uses gold-plated contacts (8.00µin thickness). Gold plating typically provides enhanced corrosion resistance and contact reliability in demanding environments.
