Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF1B-2ES-2.5RC(17) is determined by strict equivalence across the following critical parameters:

• Series: DF1B
• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 2
• Pitch: 0.098" (2.50mm)
• Number of Rows: 1
• Mounting Type: Panel Mount, Snap-In
• Contact Termination: Crimp, IDC
• Fastening Type: Locking Ramp

The substitute part DF1B-2ES-2.5RC maintains identical electrical and mechanical specifications across all critical parameters. The primary difference is product status (active vs. obsolete) and color variation (white vs. gray), neither of which affects functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The DF1B-2ES-2.5RC serves as the direct substitute for the obsolete DF1B-2ES-2.5RC(17). Both parts maintain identical mechanical and electrical specifications across all critical connector parameters, ensuring functional compatibility in existing designs.

The substitute part offers the advantage of active product status with confirmed availability (500,400 pcs in stock vs. 850 pcs for the obsolete variant). Both parts maintain equivalent RoHS compliance and MSL ratings. The substitute part carries ROHS3 certification and REACH Unaffected status, providing enhanced regulatory documentation for new designs or production transitions.

Color difference (white vs. gray) is a cosmetic variation that does not affect electrical performance or mechanical fit. Selection between these parts should be based on supply chain requirements and design specifications regarding housing color.

Frequently Asked Questions (FAQ)

Q: Are DF1B-2ES-2.5RC(17) and DF1B-2ES-2.5RC mechanically interchangeable?

A: Yes. Both parts share identical pitch (2.50mm), position count (2), mounting type (panel mount, snap-in), and fastening mechanism (locking ramp). They are mechanically interchangeable in all standard applications.

Q: What is the significance of the color difference between gray and white housings?

A: Color is a cosmetic specification that does not affect electrical performance, mechanical fit, or contact compatibility. Selection should be based on design requirements or visual identification standards in your application.

Q: Does the obsolete status of DF1B-2ES-2.5RC(17) affect its electrical performance?

A: No. Obsolete status indicates end-of-life production and declining availability. Electrical and mechanical specifications remain unchanged. The substitute part DF1B-2ES-2.5RC is recommended for new designs and ongoing production due to active status and confirmed supply.

Q: Are the RoHS compliance levels equivalent between the two parts?

A: Both parts are RoHS compliant. The substitute part carries ROHS3 certification, representing the current regulatory standard. Both meet RoHS requirements for hazardous substance restrictions.

Q: Can I use DF1B-2ES-2.5RC contacts with DF1B-2ES-2.5RC(17) housings?

A: Yes. Both housings are part of the DF1B series and accommodate identical contact specifications (female socket, crimp/IDC termination). Contact compatibility is determined by series membership and contact type, not housing color or product status.

Q: What is the MSL rating, and does it differ between these parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Storage and handling requirements are identical for both variants.
