Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF3-2S-2C(17) is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle housing
• 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)

Parts meeting these criteria are classified as parametric equivalents. Secondary variations such as color, packaging format, and manufacturer identity do not affect functional interchangeability within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

DF3-2S-2C(18) — Hirose Electric Co Ltd equivalent with identical electrical and mechanical specifications. Differs only in housing color (red vs. gray). Both parts share obsolete product status. Selection is appropriate where color differentiation is acceptable and Hirose sourcing is preferred.

0510050200 — Molex cross-manufacturer equivalent meeting all critical substitution parameters. Offers superior availability (215,801 units in stock vs. 10,818 for DF3-2S-2C(18)) and carries Last Time Buy status, providing extended procurement window. Includes ROHS3 compliance and REACH unaffected certification. Operating temperature range specified as -40°C ~ 105°C. Selection is recommended for new designs and high-volume applications requiring long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can DF3-2S-2C(18) be used as a direct replacement for DF3-2S-2C(17)?

A: Yes. Both parts are Hirose Electric Co Ltd receptacles with identical electrical and mechanical specifications: 2 positions, 2.00mm pitch, female socket contacts, crimp termination, and free hanging mounting. The only difference is housing color (red vs. gray), which does not affect functional compatibility.

Q: Is the Molex 0510050200 fully compatible with the DF3-2S-2C(17)?

A: Yes. The 0510050200 meets all critical substitution parameters: 2-position receptacle, 2.00mm pitch, female socket contacts, crimp termination, and identical MSL rating. Cross-manufacturer substitution is valid based on these matched specifications.

Q: What is the significance of the Last Time Buy status for 0510050200?

A: Last Time Buy status indicates that Molex has announced final production of this part. This provides a defined procurement window for securing inventory before discontinuation. For applications requiring long-term supply, this status should be considered in component selection strategy.

Q: Are there compliance differences between these parts?

A: DF3-2S-2C(18) is RoHS Compliant. The Molex 0510050200 is ROHS3 Compliant and REACH Unaffected. Both meet MSL 1 (Unlimited) moisture sensitivity requirements. Compliance selection depends on end-application regulatory requirements.

Q: Do these parts require specific contact types?

A: All three parts are housings only. Contacts are not included and must be sourced separately. Ensure selected contacts match the 2.00mm pitch and crimp termination specifications of the housing.
