Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF3-2S-2C(19) are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 2
• Pitch: 0.079" (2.00mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts maintain these core parameters. Variations in color, insulation material, operating temperature range, and product status are noted but do not affect functional interchangeability for the specified electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

DF3-2S-2C (Hirose Electric Co Ltd): This part is the primary substitute, offering identical electrical and mechanical specifications to the DF3-2S-2C(19). The DF3-2S-2C maintains Active product status and is available in high inventory (24,487 pcs). It carries ROHS3 compliance and REACH Unaffected status, making it suitable for new designs and ongoing production. The only difference is housing color (Black vs. Brown), which does not affect electrical performance.

DF3-2S-2C(18) (Hirose Electric Co Ltd): This part provides parametric equivalence with identical core specifications. However, it carries Obsolete product status, similar to the main part. It is suitable for direct replacement in existing applications but should not be selected for new designs due to supply constraints.

0510050200 (Molex): This part offers cross-manufacturer substitution with equivalent electrical and mechanical parameters. It carries Last Time Buy status and ROHS3 compliance. The operating temperature range (-40°C ~ 105°C) is narrower than the Hirose DF3-2S-2C (-55°C ~ 105°C), which may be a consideration for extreme low-temperature applications. The insulation material differs (PBTP vs. PA/Nylon), and the HTSUS code differs, reflecting different material composition.

Frequently Asked Questions (FAQ)

Q: Can DF3-2S-2C(19) be directly replaced with DF3-2S-2C?

A: Yes. Both parts share identical electrical and mechanical specifications: 2-position receptacle, female socket contacts, 2.00mm pitch, crimp termination, and free-hanging in-line mounting. Housing color difference (Brown vs. Black) does not affect functional interchangeability.

Q: What is the difference between DF3-2S-2C(19) and DF3-2S-2C(18)?

A: Both parts are electrically and mechanically equivalent. The primary difference is housing color: DF3-2S-2C(19) is Brown, while DF3-2S-2C(18) is Red. Both carry Obsolete status. Selection between them depends on color-coding requirements in the application.

Q: Is the Molex 0510050200 suitable as a substitute?

A: Yes, for most applications. The 0510050200 maintains all critical electrical and mechanical parameters. However, its operating temperature range (-40°C ~ 105°C) is narrower than Hirose parts (-55°C ~ 105°C). Applications requiring operation below -40°C should use Hirose equivalents. The insulation material also differs (PBTP vs. PA/Nylon).

Q: Why should I avoid DF3-2S-2C(19) and DF3-2S-2C(18) for new designs?

A: Both parts carry Obsolete product status, indicating discontinued manufacturing and limited supply availability. DF3-2S-2C (Active status) is the recommended choice for new designs. For long-term supply security, evaluate the Molex 0510050200, though it carries Last Time Buy status.

Q: Are contacts included with these connector housings?

A: No. All listed parts are housings only. Contacts must be sourced separately and are not included with the housing purchase.

Q: What compliance certifications apply to these parts?

A: DF3-2S-2C carries ROHS3 compliance and REACH Unaffected status. DF3-2S-2C(18) carries RoHS compliance. The Molex 0510050200 carries ROHS3 compliance and REACH Unaffected status. All parts have MSL rating of 1 (Unlimited).
