DF11-18DS-2DSA Equivalent & Substitute Parts

Part Overview

The DF11-18DS-2DSA is an 18-position receptacle connector manufactured by Hirose Electric Co Ltd, designed for board-to-board or cable applications with 0.079" (2.00mm) pitch mating. This connector features through-hole mounting with press-fit and solder termination options, tin-plated contacts, and operates across -30°C to 85°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the DF11-18DS-2DSA is determined by the following critical parameters: connector type (receptacle vs. header), contact type (female socket vs. male pin), number of positions (18), pitch spacing (0.079" / 2.00mm), number of rows (2), row spacing (0.079" / 2.00mm), mounting type (through hole), and electrical ratings (2A minimum, 250V minimum).

The substitute parts are grouped into two categories:

Direct Equivalent (Same Connector Type): DF11-18DS-2DSA(05) is a direct equivalent receptacle connector from the same DF11 series, maintaining identical mechanical and electrical specifications while offering active product status and improved compliance.

Mating Header Alternatives (Complementary Connector Type): B18B-PHDSS-B (JST) and SWR204-NRTN-D09-ST-GA (Sullins) are header connectors designed to mate with receptacle connectors of matching pitch and position count. These are suitable for applications requiring a complete connector pair assembly.

Engineering Selection Recommendations

For Direct Replacement (Receptacle Connector): DF11-18DS-2DSA(05) is the primary substitute. It maintains identical electrical and mechanical specifications to the original part while offering active product status and ROHS3 compliance, addressing the obsolescence of the original DF11-18DS-2DSA.

For Mating Header Applications: B18B-PHDSS-B and SWR204-NRTN-D09-ST-GA are suitable mating headers for receptacle-based connector pairs. B18B-PHDSS-B maintains the 250V voltage rating and -30°C lower temperature limit closer to the original specification. SWR204-NRTN-D09-ST-GA operates at reduced voltage (50V) and temperature range (-25°C minimum), making it suitable only for applications within these reduced electrical and thermal parameters.

All substitute options are ROHS3 compliant and carry UL94 V-0 flammability ratings, meeting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can DF11-18DS-2DSA(05) be used as a direct replacement for DF11-18DS-2DSA? A: Yes. DF11-18DS-2DSA(05) maintains identical pitch (0.079" / 2.00mm), position count (18), row configuration (2 rows), mounting type (through hole), electrical ratings (2A, 250V), and operating temperature range (-30°C ~ 85°C). The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between receptacle and header connectors in this product line? A: The DF11-18DS-2DSA is a receptacle connector with female sockets designed to receive mating pins. B18B-PHDSS-B and SWR204-NRTN-D09-ST-GA are header connectors with male pins designed to insert into receptacles. These are complementary connector types used in mating pairs for board-to-board or board-to-cable applications.

Q: Are B18B-PHDSS-B and SWR204-NRTN-D09-ST-GA interchangeable with each other? A: Both headers share identical pitch (0.079" / 2.00mm), position count (18), row configuration (2 rows), and mounting type (through hole). However, SWR204-NRTN-D09-ST-GA operates at 50V maximum voltage compared to B18B-PHDSS-B at 250V, and has a lower minimum operating temperature (-25°C vs. -25°C for B18B-PHDSS-B). Selection depends on application voltage and temperature requirements.

Q: What packaging options are available for these substitutes? A: DF11-18DS-2DSA(05) is supplied in bulk packaging. B18B-PHDSS-B packaging is not specified. SWR204-NRTN-D09-ST-GA is supplied in bulk packaging.

Q: Are all substitute parts RoHS compliant? A: Yes. DF11-18DS-2DSA(05), B18B-PHDSS-B, and SWR204-NRTN-D09-ST-GA are all ROHS3 compliant, whereas the original DF11-18DS-2DSA is RoHS non-compliant.
