Molex API Release Notes Version 2 – July 2026


New Features

  • None

Changes and Improvements

Several updates have been made across the Molex API portfolio. The Pricing API now includes lead time, stock availability and quoted quantity data, while contract pricing has been extended to surface both active and future contracts. The PCN Endpoint now supports filtering by date range. The Part Detail Endpoint adds lead time data for AirBorn US and UK manufacturing locations, expands CAD model formats and updates the compliance field USMCAExempt to reflect parts pending trade and customs review.

Pricing API—/products/pricing

The Pricing API Endpoint (/products/pricing) introduces the quotedQuantity attribute for contract pricing, which returns the quantity used as the basis for the quoted price. The endpoint has also been updated to return both active and future contracts when the information is available. Prior to this change, only active contracts were returned. Book and contract pricing now includes both leadTimeDays and leadTimeWeeks. These two new attributes provide lead time and real-time stock availability along with pricing data, reducing the need to query the Part Detail endpoint separately.

Contract Pricing

  • New attribute: quotedQuantity
    • Returns the quantity used as the basis for the quoted price

Book and Contract Pricing

  • New attributes: leadTimeDays, leadTimeWeeks, stock
    • Returns location specific lead time and real-time stock availability alongside pricing data
    • Reduces the need for querying part-detail API separately

Contract Pricing

  • Updated behavior: returns both active and future contracts (if present); previously, only active contracts were returned

PCN Endpoint—/products/pcn

  • New optional query parameters: "issueDateFrom/ issueDateTo"
    • Filters PCN results to a specified date range using the issuedDate of the product changes
    • Returns only PCNs issued within the provided issueDateFrom and issueDateTo values

Part Detail Endpoint—/products/{productNumber}

Lead Time

  • “globalLeadTimeStock” array
    • Now returns lead-time data for AirBorn products, including minimum and maximum values for both US and UK manufacturing locations

CAD Model

  • New attributes within model section of part-detail API with direct links to download CAD content
    • Model formats: “2DAltium”, “2DEagle6”, “3DStepAP242”

Export Control

  • Updated attribute: USMCAExempt
    • Updated data type from Boolean to string
  • Values now include True, False, and Under Review
    • “Under Review” value indicates that trade and customs classification for the part has not been fully completed by the Molex trade and customs team

Depreciations and Removals

  • None

Changes and Improvements

This latest release introduces new order endpoints, several enhancements, expanded pricing details and improved product documentation links. The changes add new queries and attributes to help clients filter product catalogs, distinguish product origins, retrieve ordering data and obtain richer pricing and compliance information. It also fixes a bug in which caused datasheets to be linked incorrectly.
