Substitute Part Grouping Explanation

The substitute part LF10WBPD-12S(31) is classified as a direct equivalent based on the following critical parameters that determine substitution compatibility:

Connector Configuration: Both parts maintain identical 12-position female socket plug architecture with shell size 10
Electrical Specifications: Current rating (2A) and voltage rating (30VAC, 42VDC) are identical
Mechanical Interface: Bayonet lock fastening, keyed orientation, and free-hanging in-line mounting are preserved
Environmental Protection: IP67/IP68 ingress protection rating is maintained
Termination Method: Solder cup termination is consistent across both parts
Operating Range: Temperature range of -25°C ~ 85°C is identical
Material Composition: Shell material (Zinc Alloy, Nickel finish), insert material (Polyphenylene Sulfide), and shielding characteristics are equivalent

The primary distinction is product status: LF10WBPD-12S is obsolete, while LF10WBPD-12S(31) is active with current manufacturing availability.

Engineering Selection Recommendations

LF10WBPD-12S(31) is the direct active equivalent for the obsolete LF10WBPD-12S. Selection of the substitute part is based on:

Product Availability: LF10WBPD-12S(31) maintains active manufacturing status with documented inventory availability, whereas the main part is obsolete
Regulatory Compliance: LF10WBPD-12S(31) carries ROHS3 compliance and REACH affected status, meeting current environmental regulations
Electrical and Mechanical Compatibility: All critical parameters including connector configuration, electrical ratings, fastening mechanism, and environmental protection ratings are identical
Manufacturing Continuity: Both parts share the same base product number (LF10WBPD) and are manufactured by the same supplier, ensuring design continuity

For applications currently using LF10WBPD-12S, transition to LF10WBPD-12S(31) is supported by full parameter equivalence across all functional and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Are LF10WBPD-12S and LF10WBPD-12S(31) mechanically interchangeable?

A: Yes. Both connectors maintain identical shell size (10), 12-position configuration, bayonet lock fastening, and keyed orientation. Physical mating with corresponding receptacles is identical.

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

A: The primary difference is product status and regulatory compliance. LF10WBPD-12S is obsolete, while LF10WBPD-12S(31) is active production with ROHS3 compliance and REACH affected status. The "(31)" designation indicates the bulk packaging variant.

Q: Can LF10WBPD-12S(31) be used in existing designs specified for LF10WBPD-12S?

A: Yes. Electrical specifications (2A current, 30VAC/42VDC voltage), operating temperature range (-25°C ~ 85°C), and all mechanical parameters are identical. The substitute part is fully compatible for direct replacement.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is determined by: connector type (plug, female sockets), position count (12), shell size (10), termination method (solder cup), fastening type (bayonet lock), electrical ratings (2A, 30VAC/42VDC), ingress protection (IP67/IP68), and operating temperature range (-25°C ~ 85°C).

Q: Is the contact material difference significant?

A: Both parts use gold mating contact finish. The main part specifies Phosphor Bronze contact material, while the substitute specifies Copper Alloy. Both materials are compatible with the gold finish specification and maintain equivalent electrical performance at the 2A current rating.

Q: What packaging options are available?

A: LF10WBPD-12S(31) is supplied in bulk packaging. Original packaging specifications for LF10WBPD-12S are not documented in the available data.
