Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0874371333 is determined by strict alignment across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch - mating (0.059" / 1.50mm)
• Number of positions (13)
• Number of rows (1)
• Mounting type (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact shape (Square)
• Material flammability rating (UL94 V-0)

The identified substitute parts meet these core electrical and mechanical requirements. Variations in contact finish, insulation height, fastening type, and product status are documented in the parameter comparison table below.

Engineering Selection Recommendations

The Molex 0874371333 is obsolete, necessitating substitution for new designs or ongoing procurement. Two qualified alternatives are available:

Molex 0874371343 is the direct series equivalent within the Pico-SPOX 87437 family. This part maintains identical pitch, position count, mounting configuration, and fastening type. The primary distinction is RoHS3 compliance and contact finish specification (Tin versus Tin-Lead). This part is active and available in higher inventory quantities, making it the preferred choice for designs requiring continuity within the Molex Pico-SPOX platform.

TE Connectivity 1-292230-3 is a cross-manufacturer alternative from the Mini CT series. This part satisfies all core substitution criteria: identical pitch, position count, shrouding, and termination method. Differences include fastening type (Detent Lock versus Push-Pull), contact length (0.094" versus 0.106"), and insulation height (0.272" versus 0.199"). This part is RoHS3 compliant and available in the highest inventory quantity. Selection of this alternative requires mechanical compatibility verification due to dimensional variations.

Both substitute parts carry UL94 V-0 flammability certification and are suitable for general purpose and medical applications as specified for the original part.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0874371343 be used as a direct replacement for the Molex 0874371333?

A: Yes. Both parts share identical pitch (1.50mm), position count (13), mounting type (surface mount), shrouding (4-wall), and fastening mechanism (push-pull). The primary difference is RoHS3 compliance of the 0874371343 and contact finish specification. No mechanical or electrical redesign is required.

Q: What are the key differences between the Molex 0874371343 and TE Connectivity 1-292230-3?

A: The TE Connectivity part differs in fastening type (Detent Lock versus Push-Pull), contact mating length (0.094" versus 0.106"), and insulation height (0.272" versus 0.199"). These dimensional variations may affect board layout and mating interface compatibility. Mechanical verification is required before substitution.

Q: Is the TE Connectivity 1-292230-3 compatible with existing PCB designs for the Molex 0874371333?

A: Compatibility depends on specific board layout and mating connector specifications. The TE Connectivity part maintains pitch and position alignment but introduces dimensional differences in contact length and insulation height. PCB footprint and mating interface must be evaluated for each application.

Q: What is the significance of the contact finish difference (Tin-Lead versus Tin)?

A: The original Molex 0874371333 uses Tin-Lead finish and is RoHS non-compliant. Both substitute parts use Tin finish and are RoHS3 compliant. This change reflects current regulatory requirements and does not affect electrical performance for the specified applications.

Q: Are packaging differences between the substitute parts significant?

A: The Molex 0874371343 is supplied in Cut Tape (CT) packaging, while the TE Connectivity 1-292230-3 is supplied in Tape & Reel (TR) packaging. Selection depends on production volume and assembly equipment compatibility. Both formats are standard for surface mount components.

Q: Can the fastening type difference (Push-Pull versus Detent Lock) affect system performance?

A: Fastening type affects mating and unmating force characteristics and connector retention. Push-Pull fastening (Molex parts) and Detent Lock fastening (TE Connectivity part) provide different mechanical engagement. Application requirements for connector stability and serviceability must be evaluated.
