Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LF10WBP-4P is determined by strict equivalence across the following critical parameters:

• Connector type: Plug with male pins
• Number of positions: 4
• Shell size - insert: 10
• Termination method: Solder cup
• Fastening type: Bayonet lock
• Orientation: Keyed
• Ingress protection rating: IP67/IP68
• Current rating: 10A
• Voltage rating: 125VAC/DC
• Operating temperature range: -25°C ~ 85°C
• Shell material and finish: Zinc alloy with nickel plating
• Contact finish: Gold
• Shielding: Shielded

The substitute part LF10WBP-4P(31) maintains all critical electrical and mechanical parameters required for direct substitution. The primary distinction is product status: LF10WBP-4P(31) is active and available in bulk packaging, whereas the original LF10WBP-4P is obsolete.

Parameter Comparison

Engineering Selection Recommendations

LF10WBP-4P(31) is the direct substitute for LF10WBP-4P. Both parts are manufactured by Hirose Electric Co Ltd and share identical electrical and mechanical specifications across all critical parameters.

The LF10WBP-4P(31) is classified as active product status with ROHS3 compliance and REACH affected designation, providing regulatory alignment for current manufacturing and supply chain requirements. The original LF10WBP-4P is obsolete and no longer actively produced.

For new designs or component replenishment, LF10WBP-4P(31) is the appropriate selection. Existing applications using LF10WBP-4P can transition to LF10WBP-4P(31) without modification, as all functional and mechanical parameters remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can LF10WBP-4P(31) directly replace LF10WBP-4P in existing applications?

A: Yes. Both connectors maintain identical specifications for connector type, pin count, shell size, termination method, fastening mechanism, ingress protection rating, electrical ratings, and operating temperature range. Direct substitution is supported without circuit or mechanical redesign.

Q: What is the difference between LF10WBP-4P and LF10WBP-4P(31)?

A: The primary differences are product status and packaging. LF10WBP-4P is obsolete and supplied in standard packaging. LF10WBP-4P(31) is active product with bulk packaging, ROHS3 compliance, and REACH affected status. All electrical and mechanical parameters are equivalent.
