DF3-3S-2C(18) Equivalent & Substitute Parts

Part Overview

The DF3-3S-2C(18) is a 3-position rectangular connector housing manufactured by Hirose Electric Co Ltd, designed for applications requiring 0.079" (2.00mm) pitch receptacle connections. This part is classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

The DF3-3S-2C(18) serves as a receptacle housing for crimp-terminated female socket contacts in a single-row configuration. Due to its obsolete status, direct equivalents from active product lines are necessary to maintain design compatibility and ensure supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3-3S-2C(18) is determined by strict alignment with the following electrical and mechanical parameters:

• Connector Type: Receptacle housing
• Contact Type: Female Socket
• Number of Positions: 3
• Pitch: 0.079" (2.00mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Moisture Sensitivity Level: 1 (Unlimited)

Two substitute parts meet these criteria and are identified as functionally equivalent:

1. DF3-3S-2C (Hirose Electric Co Ltd) — Direct manufacturer equivalent with identical electrical and mechanical specifications. Product Status: Active.

2. 0510050300 (Molex) — Parametric equivalent from an alternative manufacturer. Maintains all critical electrical and mechanical parameters. Product Status: Active.

Parameter Comparison

Engineering Selection Recommendations

DF3-3S-2C is the primary substitute for DF3-3S-2C(18). Both parts are manufactured by Hirose Electric Co Ltd and maintain identical electrical and mechanical specifications. The DF3-3S-2C is Active in product status and carries ROHS3 compliance, providing superior supply chain availability and regulatory alignment compared to the Obsolete DF3-3S-2C(18).

0510050300 (Molex) serves as a cross-manufacturer parametric equivalent. This part maintains all critical electrical and mechanical parameters required for functional compatibility. The 0510050300 is Active in product status and ROHS3 compliant. Selection of this alternative is appropriate when Hirose-specific sourcing constraints exist or when multi-source qualification is required.

Both substitutes are suitable for direct replacement based on provided electrical and mechanical parameters. Inventory availability is significantly higher for both active alternatives compared to the Obsolete DF3-3S-2C(18).

Frequently Asked Questions (FAQ)

Q: Can DF3-3S-2C directly replace DF3-3S-2C(18)?

A: Yes. Both parts share identical electrical and mechanical specifications: 3-position receptacle housing, 0.079" (2.00mm) pitch, female socket contacts, crimp termination, and single-row configuration. The primary difference is product status; DF3-3S-2C is Active while DF3-3S-2C(18) is Obsolete.

Q: What is the difference between DF3-3S-2C(18) and DF3-3S-2C?

A: The primary difference is housing color: DF3-3S-2C(18) is Red, while DF3-3S-2C is Black. All electrical and mechanical parameters are identical. Both are Hirose Electric Co Ltd products within the DF3 series.

Q: Can Molex 0510050300 replace DF3-3S-2C(18)?

A: Yes. The 0510050300 maintains all critical electrical and mechanical parameters: 3-position receptacle, 0.079" (2.00mm) pitch, female socket contacts, crimp termination, and single-row configuration. This is a cross-manufacturer parametric equivalent suitable for applications where multi-source qualification is acceptable.

Q: Are there packaging differences between these substitutes?

A: DF3-3S-2C(18) packaging is listed as unspecified. Both DF3-3S-2C and 0510050300 are supplied in Bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Do these parts require specific contact types?

A: All three parts are housings only. Contacts are not included. Ensure that replacement contacts are compatible with the 0.079" (2.00mm) pitch and crimp termination method specified for your application.

Q: What is the operating temperature range for these substitutes?

A: DF3-3S-2C specifies -55°C ~ 105°C operating temperature. This parameter is not provided for DF3-3S-2C(18) or 0510050300 in the available data.
