Frequently Asked Questions (FAQ)

Q: What determines whether the 0874371043 can substitute for the 0874371052?

A: Substitution is based on shared base product number (087437), identical manufacturer (Molex), matching category classification (Rectangular Connectors), equivalent MSL rating (1 - Unlimited), and aligned regulatory codes (ECCN: EAR99, HTSUS: 8536.69.4040). These parameters establish functional and regulatory equivalence within the connector family.

Q: Why is the original part 0874371052 listed as Obsolete?

A: Obsolete status indicates that Molex has discontinued production of this specific part number. The substitute part 0874371043 represents the active alternative within the same product family, ensuring continued design support and component availability.

Q: Does the RoHS compliance difference between the parts affect substitution?

A: No. The upgrade from RoHS Compliant to ROHS3 Compliant on the substitute part represents an enhanced compliance level. This upgrade does not introduce incompatibility and aligns with current regulatory standards.

Q: What is the significance of the shared base product number 087437?

A: The base product number identifies the core connector family. Both parts reference 087437, confirming they belong to the same product lineage and share fundamental design characteristics within the Pico-SPOX connector series.

Q: Are there packaging differences between these parts?

A: The main part 0874371052 does not specify packaging format in the provided data. The substitute part 0874371043 is supplied in Tape & Reel (TR) packaging, which is standard for surface mount connector components and supports automated assembly processes.

Q: How do the inventory levels affect component selection?

A: The substitute part 0874371043 maintains 24,500 pieces in stock compared to 736 pieces for the original part. Higher inventory levels support sustained procurement and reduce supply chain risk for ongoing production requirements.
