Engineering Selection Recommendations
The DF11-20DS-2C serves as the direct functional equivalent to the obsolete DF11-20DS-2C(20). Selection of the active substitute is justified on the following grounds:
- Product Status: The substitute maintains active product status with significantly higher inventory availability (500,100 pcs vs. 853 pcs), ensuring long-term supply chain continuity.
- Compliance Enhancement: The substitute achieves ROHS3 compliance, representing an upgrade from the base RoHS compliance of the original part, meeting current regulatory requirements.
- Environmental Certification: REACH Unaffected status on the substitute provides additional regulatory assurance for applications subject to chemical substance restrictions.
- Electrical & Mechanical Equivalence: All functional parameters remain identical, ensuring direct interchangeability without circuit or mechanical redesign.
Frequently Asked Questions (FAQ)
Q: Can DF11-20DS-2C be used as a direct replacement for DF11-20DS-2C(20)?
A: Yes. Both parts are identical in electrical and mechanical specifications: 20-position receptacle housing, 2.00mm pitch, 2-row configuration, crimp termination, and free hanging mounting. The substitute is the active production equivalent.
Q: What is the difference between the part numbers DF11-20DS-2C(20) and DF11-20DS-2C?
A: The designation "(20)" in the original part number indicates the 20-position configuration. The active substitute DF11-20DS-2C uses the same base designation without the position count suffix, as this is implicit in the part number structure.
Q: Are there any compatibility concerns when substituting these parts?
A: No compatibility concerns exist. The parts share identical pitch, row spacing, contact type, and mounting configuration. Mating connectors and contact pins designed for DF11-20DS-2C(20) are fully compatible with DF11-20DS-2C.
Q: What packaging options are available for the substitute part?
A: The active substitute DF11-20DS-2C is available in Bulk packaging, suitable for production assembly and integration into larger connector assemblies.
Q: Are contacts included with these connector housings?
A: No. Both the original and substitute parts are housings only. Contacts must be sourced separately and crimped into the housing according to Hirose specifications.
Q: What is the operating temperature range for these connectors?
A: The substitute part operates across -30°C to 85°C, providing adequate thermal performance for industrial and commercial applications.
