LF10WBPD-4P Equivalent & Substitute Parts

Part Overview

The LF10WBPD-4P is a 4-position circular connector plug with male pins, solder cup termination, and bayonet lock fastening manufactured by Hirose Electric Co Ltd. This connector is designed for industrial and telecommunications applications requiring IP67/IP68 ingress protection and operates across -25°C to 85°C temperature range. The product status is obsolete, necessitating identification of active equivalent alternatives to ensure continued availability and supply chain continuity for new designs and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

The LF10WBPD-4P(31) qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type, gender, and pin count match exactly (Plug, Male Pins, 4 positions)
• Shell size and insert designation are identical (Size 10)
• Termination method is identical (Solder Cup)
• Fastening mechanism is identical (Bayonet Lock)
• Electrical ratings are equal or exceed the original (10A, 125VAC/DC)
• Ingress protection classification is equal or superior (IP67/IP68)
• Operating temperature range encompasses or matches the original (-25°C ~ 85°C)
• Shielding configuration is identical (Shielded)

The LF10WBPD-4P(31) meets all substitution criteria and represents the active production equivalent of the obsolete LF10WBPD-4P.

Parameter Comparison

Engineering Selection Recommendations

The LF10WBPD-4P(31) is the direct active equivalent for the obsolete LF10WBPD-4P. Selection of the substitute part is based on:

• Identical electrical and mechanical specifications across all critical parameters
• Active product status ensuring ongoing availability and supply chain support
• ROHS3 compliance and REACH affected status of the substitute part, meeting current regulatory requirements
• Equivalent certifications and flammability ratings (UL94 V-0)
• Identical connector interface geometry and pin configuration ensuring mechanical and electrical compatibility in existing applications

The LF10WBPD-4P(31) is suitable for direct replacement in all applications previously specified for the LF10WBPD-4P.

Frequently Asked Questions (FAQ)

Q: Can the LF10WBPD-4P(31) be used as a direct replacement for the LF10WBPD-4P?

A: Yes. The LF10WBPD-4P(31) is electrically and mechanically identical to the LF10WBPD-4P across all specified parameters, including connector type, pin count, shell size, termination method, fastening mechanism, electrical ratings, and operating temperature range.

Q: What is the primary difference between these two part numbers?

A: The LF10WBPD-4P is obsolete, while the LF10WBPD-4P(31) is an active production part. The packaging differs (the main part does not specify packaging; the substitute is supplied in bulk). The substitute includes ROHS3 compliance and REACH affected status documentation.

Q: Are there any compatibility concerns when substituting the LF10WBPD-4P(31) for the LF10WBPD-4P?

A: No compatibility concerns exist. Both parts share identical shell size, pin configuration, termination interface, and fastening mechanism. Solder cup termination and bayonet lock fastening are identical between both parts.

Q: What certifications apply to the substitute part?

A: The LF10WBPD-4P(31) carries UL94 V-0 material flammability rating, ROHS3 compliance, and REACH affected status. Both parts are classified under ECCN EAR99 and HTSUS 8536.69.4020.

Q: Is the cable opening specification relevant for substitution?

A: The cable opening specification (0.287" / 7.30mm) is provided for the substitute part but not for the main part. This parameter defines the maximum cable diameter that can pass through the connector backshell and does not affect electrical or mechanical substitution compatibility.
