DF11-18DS-2DSA(01) Equivalent & Substitute Parts

Part Overview

The DF11-18DS-2DSA(01) 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 spacing. This connector features through-hole mounting, press-fit and solder termination options, and gold-plated mating contacts rated for 2A at 250V. The part is currently obsolete, necessitating identification of functionally equivalent alternatives for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution for the DF11-18DS-2DSA(01) 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(06) is a direct equivalent receptacle connector from the same DF11 series, maintaining identical mechanical and electrical specifications while offering active product status and RoHS3 compliance.

Mating Pair 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 parts are suitable for applications requiring a complete connector pair solution.

Engineering Selection Recommendations

DF11-18DS-2DSA(06) is the primary substitute for direct replacement of the DF11-18DS-2DSA(01). This part maintains identical mechanical and electrical specifications while offering active product status and RoHS3 compliance, eliminating obsolescence concerns and regulatory compliance issues associated with the original part.

B18B-PHDSS-B and SWR204-NRTN-D09-ST-GA are suitable alternatives when a complete connector pair solution is required. Both parts are active products with RoHS3 compliance. The B18B-PHDSS-B maintains the full operating temperature range of the original part (-25°C ~ 85°C vs. -30°C ~ 85°C). The SWR204-NRTN-D09-ST-GA operates at a reduced voltage rating of 50V, which may limit applicability in higher-voltage circuits compared to the 250V rating of the original receptacle.

Frequently Asked Questions (FAQ)

Q: Can DF11-18DS-2DSA(06) be used as a direct replacement for DF11-18DS-2DSA(01)?

A: Yes. Both parts are 18-position receptacle connectors from the Hirose DF11 series with identical pitch spacing (0.079" / 2.00mm), row configuration, mounting type, and electrical ratings (2A, 250V). The primary difference is product status and compliance: DF11-18DS-2DSA(06) is active and RoHS3 compliant, while DF11-18DS-2DSA(01) is obsolete and RoHS non-compliant.

Q: What is the difference between receptacle and header connectors?

A: The DF11-18DS-2DSA(01) is a receptacle connector with female sockets designed to accept male pins from a mating header connector. Headers such as B18B-PHDSS-B and SWR204-NRTN-D09-ST-GA feature male pins and are mounted on the opposite board or cable. These parts are complementary and mate together.

Q: Are B18B-PHDSS-B and SWR204-NRTN-D09-ST-GA compatible with the DF11-18DS-2DSA(01)?

A: Both header connectors share the same pitch spacing (0.079" / 2.00mm), position count (18), and row configuration (2 rows) as the DF11-18DS-2DSA(01), enabling mechanical mating. However, the SWR204-NRTN-D09-ST-GA operates at a maximum voltage rating of 50V, which is lower than the 250V rating of the receptacle. Applications requiring 250V operation should use the B18B-PHDSS-B header.

Q: What are the packaging differences among these parts?

A: DF11-18DS-2DSA(01) and B18B-PHDSS-B have unspecified packaging, while DF11-18DS-2DSA(06) and SWR204-NRTN-D09-ST-GA are supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Why is RoHS compliance important for this connector?

A: RoHS3 compliance indicates the part meets current regulatory requirements for restricted hazardous substances. The original DF11-18DS-2DSA(01) is RoHS non-compliant, which may restrict its use in new designs or applications subject to environmental regulations. DF11-18DS-2DSA(06) and both header alternatives are RoHS3 compliant.
