Engineering Selection Recommendations

Primary Substitute: Molex 2133559343

The Molex 2133559343 is the direct functional equivalent for the obsolete 2133559340. Selection of this substitute is based on the following engineering criteria:

1. Series Continuity: Both connectors belong to the MINI50 series (Base Product 213355), ensuring mechanical and electrical compatibility within the product family.

2. Electrical Specifications: The substitute maintains identical voltage (500VDC) and current (16A per contact) ratings, supporting equivalent power delivery and signal integrity requirements.

3. Physical Configuration: The 34-position, 3-row layout with 0.079" (2.00mm) pitch and 4-wall shrouded design ensures direct mechanical compatibility with existing mating connectors and PCB layouts.

4. Termination and Mounting: Solder termination with through-hole, right-angle mounting provides identical assembly and integration methods to the original part.

5. Compliance and Certification: The substitute maintains UL94 V-0 material flammability rating and EAR99 export classification, preserving regulatory compliance for the original design.

6. Product Status: The active status of the 2133559343 ensures ongoing availability, supply chain support, and manufacturer technical documentation for current and future production requirements.

Frequently Asked Questions (FAQ)

Q: Why is the Molex 2133559340 no longer available?

A: The 2133559340 has reached end-of-life status and is classified as Obsolete. Molex has transitioned this product line to the active 2133559343 variant, which provides equivalent functionality with enhanced supply chain continuity.

Q: Can the Molex 2133559343 be used as a direct replacement in existing designs?

A: Yes. The 2133559343 maintains identical electrical specifications (500VDC, 16A per contact), mechanical configuration (34-position, 0.079" pitch, 4-wall shrouded), and termination method (solder). No design modifications are required for direct substitution.

Q: Are there any differences in mounting orientation between the two parts?

A: The 2133559343 is specified as a through-hole, right-angle mount connector. Verify that your PCB layout accommodates right-angle mounting. If the original 2133559340 used a different mounting orientation, mechanical layout adjustment may be necessary.

Q: What is the significance of the 3-row configuration in the substitute part?

A: The 3-row arrangement with 34 total positions (typically 12-12-10 or similar distribution) is the standard MINI50 series configuration for this position count. This maintains compatibility with standard MINI50 mating connectors and receptacles.

Q: Does the substitute part maintain RoHS compliance?

A: The original 2133559340 is RoHS Compliant. The substitute 2133559343 is manufactured to current Molex standards and maintains equivalent environmental compliance. Confirm RoHS certification status with Molex technical documentation for your specific procurement batch.

Q: What is the current inventory status for the substitute part?

A: The Molex 2133559343 is actively manufactured and stocked. Current inventory availability should be confirmed through authorized Molex distributors or the manufacturer's supply chain management system.

Q: Are there any thermal or environmental limitations I should consider?

A: The substitute part operates across the -40°C to 105°C temperature range, which is standard for industrial and commercial applications. Verify that your application environment falls within this specification.

Q: What contact material and finish are used in the substitute connector?

A: The 2133559343 features brass contacts with tin plating on both mating and post surfaces. This provides corrosion resistance and reliable electrical conductivity for solder termination and mating cycles.
