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

Part Overview

The DF3-2S-2C(18) is a 2-position rectangular connector housing manufactured by Hirose Electric Co Ltd, designed for applications requiring crimp-terminated female socket receptacles with 2.00mm pitch. This part is classified as Obsolete, necessitating identification of equivalent alternatives for ongoing procurement and system maintenance. The connector operates as a free-hanging in-line receptacle housing without integrated contacts, requiring separate contact procurement.

Substitute Part Grouping Explanation

Substitution for the DF3-2S-2C(18) is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (2), pitch (2.00mm), number of rows (1), mounting type (free hanging in-line), and contact termination method (crimp). All identified substitutes maintain these core electrical and mechanical specifications, ensuring functional interchangeability within the connector interface.

Two substitute parts meet these criteria:

Direct Manufacturer Equivalent: DF3-2S-2C from Hirose Electric Co Ltd maintains identical specifications with Active product status and enhanced compliance documentation.

Parametric Equivalent: 0510050200 from Molex provides equivalent electrical and mechanical performance across all critical parameters, though with different insulation material and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

DF3-2S-2C is the primary substitute for DF3-2S-2C(18). Both parts are manufactured by Hirose Electric Co Ltd and maintain identical electrical and mechanical specifications. The DF3-2S-2C carries Active product status with ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the Obsolete DF3-2S-2C(18). The primary distinction is housing color (Black versus Red), which does not affect electrical performance or mechanical compatibility.

0510050200 from Molex serves as a parametric equivalent when Hirose parts are unavailable. This part maintains all critical connector specifications and holds ROHS3 compliance. However, the 0510050200 carries Last Time Buy status, indicating limited future availability. The operating temperature range (-40°C ~ 105°C) is narrower than the DF3-2S-2C (-55°C ~ 105°C), requiring verification against application requirements in extreme low-temperature environments.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical connector type, contact type, position count, pitch, row configuration, mounting type, and termination method. The DF3-2S-2C is the direct successor with Active status and enhanced compliance documentation.

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

A: Color (Red versus Black) is a cosmetic distinction that does not affect electrical performance, mechanical fit, or functional compatibility. Selection between these variants depends on application-specific color coding requirements.

Q: Is 0510050200 fully compatible with DF3-2S-2C(18)?

A: The 0510050200 maintains electrical and mechanical equivalence across all critical parameters: 2-position, 2.00mm pitch, female socket receptacle, crimp termination, and free-hanging in-line mounting. Cross-manufacturer substitution is valid when these parameters align.

Q: What should be considered when selecting between DF3-2S-2C and 0510050200?

A: DF3-2S-2C is preferred due to Active product status and extended operating temperature range (-55°C ~ 105°C). The 0510050200 should be selected only when DF3-2S-2C is unavailable, with verification that the -40°C ~ 105°C operating range meets application requirements.

Q: Are contacts included with these connector housings?

A: No. All three parts (DF3-2S-2C(18), DF3-2S-2C, and 0510050200) are housings only. Contacts must be procured separately and must be compatible with 2.00mm pitch crimp termination specifications.

Q: What compliance certifications apply to these parts?

A: DF3-2S-2C(18) and DF3-2S-2C are RoHS Compliant and ROHS3 Compliant respectively. The 0510050200 is ROHS3 Compliant. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions.
