Molex 0874381033 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0874381033 is a surface mount, right-angle rectangular connector header with 10 positions at 1.5mm pitch, designed for board-to-cable/wire applications in general purpose and medical equipment. This part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support, production continuity, and system maintenance. Active alternatives with compatible electrical and mechanical parameters are available to ensure uninterrupted supply chain access.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0874381033 is determined by strict alignment of the following critical parameters:

• Connector type (Header) and contact type (Male Pin)
• Pitch specification (0.059" / 1.50mm)
• Position count (10 positions, single row)
• Mounting configuration (Surface Mount, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Voltage rating (minimum 250V)
• Operating temperature range (minimum -55°C ~ 105°C)
• Flammability compliance (UL94 V-0)

Two substitute parts meet these criteria: the Molex 0874381043 (direct manufacturer equivalent) and the TE Connectivity 1-292228-0 (cross-manufacturer alternative). Both maintain functional and electrical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Molex 0874381043 is the primary substitute for the obsolete Molex 0874381033. Both parts belong to the Pico-SPOX 87438 series and share identical electrical and mechanical specifications. The 0874381043 is currently in active production with substantial inventory availability (53,751 pcs). This part achieves ROHS3 compliance, addressing regulatory requirements that the original part does not meet. The contact finish has been updated from Tin-Lead to Tin, aligning with modern manufacturing standards. This direct manufacturer equivalent is the preferred choice for design continuity and supply chain stability.

TE Connectivity 1-292228-0 serves as a cross-manufacturer alternative when Molex supply is constrained. This part maintains core connector functionality with identical pitch, position count, mounting configuration, and shrouding. However, engineering teams must account for the following differences: the contact length at mating is 0.094" (2.40mm) versus 0.106" (2.70mm) on the original, insulation height is 0.193" (4.90mm) versus 0.175" (4.45mm), and the voltage rating is 50VAC versus 250V. The operating temperature minimum is -30°C versus -55°C. These dimensional and electrical variations require PCB layout verification and connector cavity assessment before implementation. The TE part includes solder retention features and is ROHS3 compliant with active production status.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0874381043 be used as a direct replacement for the 0874381033 without PCB modification?

A: Yes. Both parts share identical pitch (1.50mm), position count (10), mounting type (surface mount right-angle), shrouding (4-wall), and contact length specifications. No PCB layout changes are required for this substitution.

Q: What is the primary difference between the Molex 0874381033 and 0874381043?

A: The 0874381043 is the active production equivalent. Key differences include product status (active vs. obsolete), RoHS compliance (ROHS3 vs. non-compliant), and contact finish (Tin vs. Tin-Lead). Electrical and mechanical performance remain equivalent.

Q: Can the TE Connectivity 1-292228-0 be used in place of the Molex 0874381033?

A: Functional substitution is possible with design verification. The TE part maintains pitch, position count, and mounting configuration. However, contact length (0.094" vs. 0.106"), insulation height (0.193" vs. 0.175"), and voltage rating (50VAC vs. 250V) differ. PCB cavity depth and connector mating force requirements must be assessed before implementation.

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

A: The Molex 0874381043 is supplied in Tape & Reel (TR) packaging. The TE Connectivity 1-292228-0 is also supplied in Tape & Reel (TR) packaging. Both support high-volume production workflows.

Q: Are there RoHS compliance considerations for these substitutes?

A: The original Molex 0874381033 is RoHS non-compliant. Both substitute parts (Molex 0874381043 and TE Connectivity 1-292228-0) are ROHS3 compliant, meeting current regulatory requirements for new designs and production.

Q: What is the minimum operating temperature range for each part?

A: The Molex 0874381033 and 0874381043 both operate from -55°C to 105°C. The TE Connectivity 1-292228-0 operates from -30°C to 105°C. Applications requiring -55°C operation must use Molex parts.

Q: How do the contact finishes differ between these parts?

A: The Molex 0874381033 uses Tin-Lead finish (100.0µin / 2.54µm thickness). The Molex 0874381043 and TE Connectivity 1-292228-0 both use Tin finish. Tin-Lead finishes are restricted in many jurisdictions; Tin finishes align with current manufacturing standards.
