Browse Molex alternativesStart with the product drawing
View product details and Zeakka product drawings to review dimensions, pitch, circuit count and configuration. These drawings support candidate selection; they are not original JST or Molex drawings or proof of approved interchangeability. Confirm the drawing revision for the selected part before sample review.

Product detailsWhat needs to be checked
- 01
Geometry and mating
Compare dimensions, orientation, keying, latch and the actual mating part. A matching pitch or similar appearance alone does not confirm fit.
- 02
Terminals, wire and operating conditions
Review terminal selection, wire size, crimp requirements, current, voltage and the electrical and environmental conditions of your application. Confirm any sealing, IP rating or certification requirements for the selected candidate.
- 03
Customer sample validation
Zeakka coordinates samples and clarifies specification questions with suitable factories. The customer validates fit, function and performance in the intended application before production approval; no blanket drop-in or equivalent-performance guarantee applies.

MOQ, availability, lead time and documentation are confirmed for the selected part and quantity. Discuss required certificates and test-report scope with us for your project.
Need a finished cable assembly?
Send connector references, pinout, wire requirements and length for an assembly review. We can source original JST or Molex connectors for finished cable assemblies; original connectors are not sold separately.
Questions before choosing an alternative
Do alternatives carry JST or Molex trademarks?
No. The alternative connectors do not carry JST or Molex trademarks. Some may carry a supplier's own brand or model. Series references identify the requested interface; they do not indicate brand affiliation or authorization.
Is the same pitch enough to confirm compatibility?
No. Geometry, mating, terminals, wire and operating conditions must also be reviewed. The customer must validate a sample in the actual application.
What do the available drawings show?
They are Zeakka product drawings for reviewing candidate dimensions and configurations. They do not establish approved interchangeability or transfer original-brand ratings and certifications to an alternative.
How are price, MOQ and supporting documents confirmed?
We review the selected part, quantity and requirements with a suitable factory. Availability, lead time, documents, required certificates and test-report scope are confirmed for that project.
Can I order original JST or Molex connectors?
We can source original connectors as components of finished cable assemblies. We do not sell original JST or Molex connectors separately. Send your assembly requirements for review.
Share your connector requirement
Send the reference, mating details and quantity with a drawing or photo. We will review the request, clarify open specification questions and coordinate suitable candidates and samples.
