Molex 0022112031 Equivalent & Substitute Parts

Part Overview

The Molex 0022112031 is an unshrouded rectangular connector header designed for through-hole mounting in board-to-board or cable applications. This 3-position, single-row header operates at 0.100" (2.54mm) pitch and features male pin contacts with gold-plated mating surfaces and tin-plated posts. The connector is actively manufactured and maintains full RoHS3 compliance with UL94 V-0 flammability rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the original part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022112031 is determined by strict alignment of the following critical parameters:

• Connector type: Header
• Contact type: Male pin
• Pitch: 0.100" (2.54mm)
• Position count: 3
• Row configuration: Single row
• Mounting method: Through hole
• Shrouding: Unshrouded
• Fastening mechanism: Push-pull
• Mating contact finish: Gold
• Insulation material flammability: UL94 V-0
• Regulatory compliance: RoHS compliant

The identified substitute parts, Amphenol ICC (FCI) 78229-103HLF and 78229-203HLF, satisfy all critical substitution criteria. Both parts are manufactured under the BERGSTIK® II series and maintain identical pitch, position count, row configuration, mounting type, and fastening mechanism. Both achieve UL94 V-0 flammability rating and RoHS compliance. Variations in contact finish thickness and insulation material composition do not preclude substitution when functional and mechanical compatibility is maintained.

Parameter Comparison

Engineering Selection Recommendations

Both Amphenol ICC (FCI) substitute parts maintain active product status and full regulatory compliance equivalent to the original Molex 0022112031. The BERGSTIK® II series connectors satisfy all critical electrical and mechanical compatibility requirements for direct substitution.

The Amphenol ICC 78229-103HLF and 78229-203HLF differ primarily in contact finish thickness on the mating surface (30.0µin versus 15.0µin respectively) and insulation material composition (PCT glass-filled versus polyamide). Both achieve UL94 V-0 flammability certification and maintain RoHS compliance. Contact length variations between the original and substitute parts are within acceptable tolerance ranges for standard through-hole PCB applications.

Selection between the two Amphenol ICC alternatives depends on specific application requirements regarding contact finish durability and insulation material properties. Both parts are actively manufactured and available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can Amphenol ICC 78229-103HLF and 78229-203HLF be used interchangeably with Molex 0022112031?

A: Yes. Both Amphenol ICC parts satisfy the critical substitution parameters: 3-position, single-row, 0.100" pitch header with male pins, through-hole mounting, unshrouded design, push-pull fastening, gold-plated mating contacts, UL94 V-0 flammability rating, and RoHS compliance. Mechanical and electrical compatibility is maintained for board-to-board and cable applications.

Q: What are the differences between Amphenol ICC 78229-103HLF and 78229-203HLF?

A: The primary differences are contact finish thickness on the mating surface (30.0µin for 78229-103HLF versus 15.0µin for 78229-203HLF) and insulation material composition (both use PCT glass-filled material). Both parts maintain identical pitch, position count, mounting type, and compliance certifications.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: Contact length and insulation height dimensions vary slightly between the original and substitute parts. The Molex 0022112031 has an insulation height of 0.130" (3.30mm), while both Amphenol ICC parts measure 0.100" (2.54mm). These variations are within acceptable ranges for standard through-hole PCB applications but should be verified against specific board layout and mating connector specifications.

Q: Do all three parts meet the same regulatory and compliance standards?

A: Yes. All three parts are RoHS compliant, achieve UL94 V-0 flammability rating, maintain MSL 1 (Unlimited) moisture sensitivity level, and carry REACH Unaffected status. ECCN and HTSUS classifications are identical across all parts.

Q: What is the difference in insulation material between the original and substitute parts?

A: The Molex 0022112031 uses polyamide (PA) nylon insulation, while both Amphenol ICC substitute parts use polycyclohexylenedimethylene terephthalate (PCT) with glass filling. Both materials achieve UL94 V-0 flammability certification and are suitable for the specified applications.
