Würth Elektronik 623310235321 WR-PHD 1.27 MM DUAL SMT SOCKET H Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 623310235321 is a 10-position rectangular connector receptacle designed for board-to-board applications. This surface mount connector operates at 1A current rating and 100VAC voltage rating, with a 0.050" (1.27mm) pitch configuration. The connector features a push-pull fastening mechanism, gold-plated contacts, and is housed in a black polyamide (PA9T) insulation body rated UL94 V-0. The product maintains active status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified to address inventory availability, lead time constraints, or specific application requirements while maintaining electrical and mechanical compatibility within the defined parameter specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors in the 0.050" (1.27mm) pitch category is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 10
• Pitch - mating: 0.050" (1.27mm)
• Number of rows: 2
• Row spacing - mating: 0.050" (1.27mm)
• Connector type: Receptacle
• Contact type: Female socket
• Mounting type: Surface mount
• Termination: Solder
• Fastening type: Push-pull
• Contact finish - mating: Gold
• Material flammability rating: UL94 V-0
• RoHS status: ROHS3 compliant
• Moisture sensitivity level: 1 (Unlimited)

The Samtec Inc. CLP-105-02-G-D-BE meets all mandatory matching parameters and qualifies as a direct substitute. While the substitute part exhibits enhanced electrical ratings (3.3A per contact versus 1A, and 240VAC/330VDC versus 100VAC) and different insulation material (LCP versus PA9T), these represent performance improvements that do not compromise compatibility in applications designed for the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the Würth Elektronik 623310235321 and Samtec Inc. CLP-105-02-G-D-BE connectors maintain active product status and full compliance with ROHS3 and REACH regulations. Both components are classified as EAR99 and share identical HTSUS coding, confirming regulatory equivalence.

The Samtec CLP-105-02-G-D-BE substitute part provides enhanced electrical performance characteristics, including higher current capacity (3.3A per contact versus 1A) and extended voltage rating (240VAC/330VDC versus 100VAC). The substitute also features an expanded operating temperature range (-55°C to 125°C versus -40°C to 105°C) and utilizes liquid crystal polymer insulation material in place of polyamide, offering improved dimensional stability and thermal performance.

Both connectors maintain identical mechanical compatibility: 10-position configuration, 0.050" (1.27mm) pitch, 2-row layout, surface mount solder termination, and push-pull fastening. Insulation heights are nominally equivalent (0.083" versus 0.084"), and both employ gold-plated mating contacts with UL94 V-0 flammability ratings.

Selection between these parts should be based on application-specific electrical requirements and inventory availability. The substitute part is suitable for applications requiring higher current capacity or extended operating temperature ranges while maintaining full mechanical and electrical compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the Samtec CLP-105-02-G-D-BE be used as a direct replacement for the Würth Elektronik 623310235321?

A: Yes. Both connectors share identical mechanical specifications: 10 positions, 0.050" (1.27mm) pitch, 2-row configuration, surface mount solder termination, and push-pull fastening. Mating interface dimensions are equivalent, and both employ gold-plated female socket contacts. The substitute part meets or exceeds all electrical and compliance requirements of the original specification.

Q: What are the key differences between these two connector models?

A: The primary differences are: (1) Current rating: Samtec CLP-105-02-G-D-BE is rated 3.3A per contact versus 1A for the Würth part; (2) Voltage rating: Samtec part supports 240VAC/330VDC versus 100VAC for the Würth part; (3) Operating temperature range: Samtec part operates -55°C to 125°C versus -40°C to 105°C for the Würth part; (4) Insulation material: Samtec uses liquid crystal polymer (LCP) versus polyamide (PA9T) for the Würth part; (5) Contact material: Samtec uses phosphor bronze versus copper alloy for the Würth part; (6) Packaging: Samtec is supplied in tube packaging versus tape and reel for the Würth part.

Q: Are there any compatibility concerns with the different insulation materials?

A: No. Both polyamide (PA9T) and liquid crystal polymer (LCP) insulation materials are suitable for board-to-board connector applications. Both materials meet UL94 V-0 flammability requirements and maintain equivalent moisture sensitivity levels (MSL 1). The LCP material in the substitute part provides enhanced dimensional stability and thermal performance.

Q: Do both connectors have the same mating interface dimensions?

A: Yes. Both connectors feature identical pitch (0.050" / 1.27mm), row spacing (0.050" / 1.27mm), and number of positions (10 in 2 rows). Insulation heights are nominally equivalent (0.083" for Würth versus 0.084" for Samtec), representing a 0.001" (0.04mm) difference within typical manufacturing tolerances.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the Würth Elektronik 623310235321 and Samtec Inc. CLP-105-02-G-D-BE are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference in packaging between these two parts?

A: The Würth Elektronik 623310235321 is supplied in tape and reel (TR) packaging, suitable for automated pick-and-place assembly. The Samtec CLP-105-02-G-D-BE is supplied in tube packaging. Packaging selection should be based on assembly process requirements and handling procedures.

Q: Can the substitute part handle higher current and voltage than the original specification?

A: Yes. The Samtec CLP-105-02-G-D-BE is rated for 3.3A per contact and 240VAC/330VDC, compared to 1A and 100VAC for the Würth part. These enhanced ratings do not affect compatibility with applications designed for the original specification. The substitute part is suitable for applications requiring higher electrical performance.
