DRC18-40SA Equivalent & Substitute Parts

Part Overview

The DRC18-40SA is a 40-position rectangular connector plug housing manufactured by TE Connectivity Deutsch Connectors. This connector features female socket contacts, screw lock fastening, and is rated for operating temperatures from -55°C to 125°C. The housing is constructed from polyphenylene sulfide (PPS) with glass filling and includes integrated dust and moisture protection features (IP68). The part is actively produced and ROHS3 compliant, making it suitable for industrial and harsh environment applications where reliable electrical connections are required. Identification of equivalent substitute parts becomes necessary when the primary part experiences supply constraints, extended lead times, or inventory limitations.

Key Parameters

Substitute Part Grouping Explanation

The DRC26-40SB is classified as a parametric equivalent to the DRC18-40SA based on the following critical matching parameters:

Matching Electrical and Mechanical Specifications:

• Connector type: Plug
• Contact type: Female Socket
• Position count: 40
• Row configuration: 4 rows
• Mounting configuration: Free Hanging (In-Line)
• Contact termination method: Crimp
• Fastening mechanism: Screw Lock
• Housing color: Black
• Environmental protection: Cap (Cover), Dust, IP68
• Operating temperature range: -55°C to 125°C
• Contacts not included in both housings

Allowable Variation: The primary difference between these parts is the insulation material composition. The DRC18-40SA uses polyphenylene sulfide (PPS) with glass filling, while the DRC26-40SB uses plastic insulation material. Both materials satisfy the electrical and thermal requirements for this connector class and maintain compatibility with the specified operating temperature range and environmental protection rating.

Parameter Comparison

Engineering Selection Recommendations

Both the DRC18-40SA and DRC26-40SB are active products manufactured by TE Connectivity Deutsch Connectors and carry ROHS3 compliance certification. Selection between these parts should be based on the following criteria:

DRC18-40SA Selection Criteria:

• Primary choice when polyphenylene sulfide (PPS) glass-filled insulation material is specified in design documentation
• Preferred when moisture sensitivity level (MSL) rating of 1 (Unlimited) is required
• Suitable for applications where REACH Unaffected status is a procurement requirement

DRC26-40SB Selection Criteria:

• Acceptable alternative when plastic insulation material meets application requirements
• Suitable for applications where REACH Affected status is acceptable
• Available as substitute when DRC18-40SA experiences supply constraints

Both connectors maintain identical electrical and mechanical specifications, including the 40-position configuration, 4-row layout, screw lock fastening, crimp termination, and IP68 environmental protection rating. The operating temperature range of -55°C to 125°C is identical for both parts.

Frequently Asked Questions (FAQ)

Q: Can the DRC26-40SB be used as a direct replacement for the DRC18-40SA in existing designs?

A: The DRC26-40SB is electrically and mechanically compatible with the DRC18-40SA. Both connectors share identical specifications for connector type, contact configuration, position count, row arrangement, mounting method, fastening type, and environmental protection rating. The primary difference is the insulation material composition. Compatibility depends on whether the application design specifies polyphenylene sulfide (PPS) glass-filled material as a requirement. If the design does not explicitly require PPS material, the DRC26-40SB is a valid substitute.

Q: What is the significance of the insulation material difference between these parts?

A: The DRC18-40SA uses polyphenylene sulfide (PPS) with glass filling, while the DRC26-40SB uses plastic insulation material. Both materials are rated for the same operating temperature range (-55°C to 125°C) and support the same electrical and mechanical performance requirements. The material difference does not affect the connector's ability to maintain the IP68 protection rating or screw lock fastening integrity.

Q: Are there any compliance differences between the DRC18-40SA and DRC26-40SB?

A: Both parts are ROHS3 compliant. The DRC18-40SA is REACH Unaffected, while the DRC26-40SB is REACH Affected. Both parts carry the same ECCN (EAR99) and HTSUS (8536.69.8000) classifications. The moisture sensitivity level (MSL) for the DRC18-40SA is rated as 1 (Unlimited), while the DRC26-40SB lists MSL as Not Applicable.

Q: Do these connectors include contacts in the housing?

A: No. Both the DRC18-40SA and DRC26-40SB are connector housings only. Contacts must be sourced separately and installed using the crimp termination method. The 40-position configuration requires 40 individual female socket contacts to be procured and assembled into the housing.

Q: What is the significance of the screw lock fastening type?

A: The screw lock fastening mechanism provides a secure, reusable connection method suitable for applications requiring frequent mating and unmating cycles. Both the DRC18-40SA and DRC26-40SB employ identical screw lock fastening, ensuring consistent connection reliability and repeatability across substitution scenarios.

Q: Can these connectors be used in harsh environmental conditions?

A: Yes. Both connectors feature IP68 environmental protection rating, which includes integrated dust and moisture protection. The operating temperature range of -55°C to 125°C supports operation in extreme thermal environments. The cap (cover) feature provides additional protection for unmated connectors.
