Molex 0874371233 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0874371233 is a surface mount rectangular connector header designed for board-to-cable/wire applications. This 12-position, 1.5mm pitch connector features a shrouded 4-wall design with solder termination and push-pull fastening. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0874371233 is determined by the following critical parameters:

• Pitch - Mating: 0.059" (1.50mm) - exact match required
• Number of Positions: 12 - exact match required
• Connector Type: Header - exact match required
• Contact Type: Male Pin - exact match required
• Mounting Type: Surface Mount - exact match required
• Shrouding: Shrouded - 4 Wall - exact match required
• Termination: Solder - exact match required
• Style: Board to Cable/Wire - exact match required

The substitute parts listed below satisfy all critical electrical and mechanical parameters. Variations in contact finish, insulation material composition, fastening mechanism, and compliance status are documented in the parameter comparison table.

Engineering Selection Recommendations

Molex 0874371243 is the primary substitute for the obsolete Molex 0874371233. Both parts share identical series designation (Pico-SPOX 87437), pitch, position count, and mechanical configuration. The 0874371243 is currently in active production status with ROHS3 compliance, addressing the regulatory limitations of the original part. The contact finish differs from tin-lead to tin, and insulation material composition varies slightly, but these changes do not affect functional compatibility for board-to-cable/wire applications. This part is the direct evolutionary replacement within the Molex product line.

TE Connectivity 1-292230-2 serves as a cross-manufacturer alternative when Molex parts are unavailable. This Mini CT series header maintains the critical 12-position, 1.5mm pitch, surface mount, shrouded configuration. Notable differences include detent lock fastening (versus push-pull), reduced contact mating length (0.094" versus 0.106"), and increased insulation height (0.272" versus 0.199"). The TE part includes specified operating temperature range (-30°C ~ 105°C) and voltage rating (50VAC). ROHS3 compliance and active product status support long-term availability. Physical dimension variations require mechanical validation before implementation in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0874371243 be used as a direct replacement for the 0874371233?

A: Yes. Both parts are from the same Pico-SPOX 87437 series with identical pitch (1.50mm), position count (12), mounting type (surface mount), and shrouding configuration. The 0874371243 is the active production equivalent and is recommended for new designs and ongoing procurement.

Q: What are the key differences between the Molex 0874371243 and TE Connectivity 1-292230-2?

A: The primary differences are fastening mechanism (push-pull versus detent lock), contact mating length (0.106" versus 0.094"), and insulation height (0.199" versus 0.272"). Both maintain the required 1.50mm pitch and 12-position configuration. The TE part includes specified operating temperature and voltage ratings. Mechanical compatibility must be verified for applications with tight spatial constraints.

Q: Are there RoHS compliance considerations when substituting the 0874371233?

A: Yes. The original 0874371233 is RoHS non-compliant. Both substitute parts (Molex 0874371243 and TE Connectivity 1-292230-2) are ROHS3 compliant, making them suitable for applications requiring RoHS adherence.

Q: What is the difference between push-pull and detent lock fastening?

A: Push-pull fastening (Molex parts) uses a mechanical push-pull mechanism for mating and unmating. Detent lock fastening (TE Connectivity 1-292230-2) uses a locking mechanism that requires deliberate action to release. Selection depends on application requirements for connection security and frequency of mating cycles.

Q: Can the TE Connectivity 1-292230-2 be used in applications originally designed for the Molex 0874371233?

A: Functional compatibility exists due to matching pitch, position count, and connector type. However, physical dimension differences (contact length and insulation height) require mechanical validation. The different fastening mechanism and increased insulation height may affect PCB layout and mating interface design. Engineering review is necessary before implementation.

Q: What packaging options are available for these substitute parts?

A: The Molex 0874371243 and TE Connectivity 1-292230-2 are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original 0874371233 packaging specification was not provided.
