Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF1B-2ES-2.5RC(15) is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (2)
• Pitch specification (2.50mm)
• Number of rows (1)
• Mounting configuration (Panel Mount, Snap-In)
• Contact termination methods (Crimp, IDC)
• Fastening mechanism (Locking Ramp)
• Series designation (DF1B)

The substitute part DF1B-2ES-2.5RC meets all these criteria and is therefore electrically and mechanically compatible with the original part number.

Parameter Comparison

Engineering Selection Recommendations

The DF1B-2ES-2.5RC is the direct substitute for the obsolete DF1B-2ES-2.5RC(15). Both parts maintain identical electrical and mechanical specifications across all critical parameters, ensuring functional compatibility in existing designs.

The substitute part DF1B-2ES-2.5RC carries active product status, providing assured supply chain availability and ongoing manufacturer support. The part is ROHS3 compliant, meeting current regulatory requirements. The only functional difference is the housing color (white versus black), which does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can DF1B-2ES-2.5RC be used as a direct replacement for DF1B-2ES-2.5RC(15)?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: connector type, contact configuration, position count, pitch, mounting method, termination type, and fastening mechanism.

Q: What is the significance of the color difference between the two parts?

A: The original part features black housing while the substitute features white housing. Color is a cosmetic attribute and does not affect electrical performance, mechanical fit, or functional compatibility.

Q: Are there any compliance differences between the two parts?

A: The original part is RoHS Compliant. The substitute part is ROHS3 Compliant, which represents a more current regulatory standard. Both parts meet applicable environmental and safety requirements.

Q: Does the active product status of DF1B-2ES-2.5RC affect its suitability as a substitute?

A: Active product status indicates ongoing manufacturer production and support, ensuring reliable supply chain availability and technical documentation access. This is advantageous for long-term design support and procurement.

Q: Are the contact termination options identical between both parts?

A: Yes. Both parts support crimp and IDC (insulation displacement contact) termination methods, providing equivalent flexibility in assembly and integration approaches.
