Moisture Sensitivity Consistency: Both parts are rated MSL 1 (Unlimited), indicating equivalent handling and storage requirements with no moisture sensitivity constraints.

Series Family Continuity: Both components share the Pico-SPOX 87437 series designation and identical base product number 087437, confirming design family compatibility and interchangeability within the connector ecosystem.

Inventory Availability: The substitute part maintains significantly higher inventory levels (2501 units) compared to the main part (679 units), supporting sustained procurement requirements.

Frequently Asked Questions (FAQ)

Q: Why is the 0874371452 being phased out?

A: The 0874371452 is designated as Obsolete. The Molex 0874371443 represents the active continuation within the Pico-SPOX 87437 series family, providing equivalent functionality with ongoing manufacturer support.

Q: Are the 0874371452 and 0874371443 mechanically compatible?

A: Both parts share the identical base product number 087437 and belong to the Pico-SPOX 87437 series. Mechanical compatibility is established through series family alignment. The 0874371443 specifies 14 positions with 0.059" (1.50mm) pitch mating and surface mount configuration.

Q: What are the key electrical parameters for substitution?

A: The provided specifications do not include voltage rating or current rating parameters for either part. Substitution decisions must be based on the documented parameters: connector type (Header), contact type (Male Pin), pitch (0.059" / 1.50mm), number of positions (14), and termination method (Solder).

Q: Does the packaging format affect substitution?

A: The 0874371443 is supplied in Tape & Reel (TR) packaging. Packaging format does not affect electrical or mechanical compatibility but may impact procurement workflows and handling procedures. Verify packaging requirements for your specific assembly process.

Q: Are both parts RoHS compliant?

A: Yes. The 0874371452 is RoHS Compliant, and the 0874371443 is ROHS3 Compliant. Both meet RoHS requirements. The ROHS3 designation on the substitute indicates compliance with the current RoHS 3 directive.

Q: What is the moisture sensitivity level for these parts?

A: Both the 0874371452 and 0874371443 are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints. Standard handling procedures apply without special moisture control requirements.

Q: Can the 0874371443 be used in medical applications?

A: The 0874371443 documentation specifies General Purpose and Medical applications. Verify that your specific medical application requirements align with the connector's documented specifications and certifications.

Q: What is the mated stacking height of the substitute part?

A: The 0874371443 specifies a mated stacking height of 7.4mm. Confirm this dimension is compatible with your mechanical design constraints.
