Molex 0901220925 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0901220925 is an active-status rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This 10-position, 2-row connector with 0.100" (2.54mm) pitch serves general purpose and automotive applications. Alternative equivalent parts may be required due to packaging availability, inventory constraints, or specific design requirements for contact finish specifications or mechanical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0901220925 is determined by strict equivalence across the following critical parameters:

• Connector type (Header, Breakaway)
• Contact type (Male Pin)
• Pitch - mating (0.100" / 2.54mm)
• Number of positions (10) and rows (2)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact shape (Square)
• Insulation material category (Polyester, Glass Filled or equivalent thermoplastic)
• Material flammability rating (UL94 V-0)
• RoHS3 compliance status

The identified substitute parts meet all critical electrical and mechanical parameters. Variations in contact finish thickness, contact length specifications, and packaging format (Tray vs. Bulk) do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full ROHS3 compliance with UL94 V-0 flammability certification. Selection between these equivalents is based on the following factors:

Molex 0901220765 is functionally equivalent to the primary part within the same C-Grid III 90122 series. The reduced gold contact finish thickness (15.0µin vs. 30.0µin) represents a cost optimization variant. This part is available in bulk packaging and offers the highest inventory availability (4311 units).

TE Connectivity 5-103801-5 provides cross-manufacturer equivalence from the AMPMODU Mod II series. This part specifies operating temperature range (-65°C ~ 105°C) and current rating (3A), with contact material specified as copper alloy rather than brass. Mechanical dimensions show minor variations in contact length specifications (0.230" mating vs. 0.266", 0.090" post vs. 0.114"). This part is available in tray packaging.

All three parts are suitable for general purpose and automotive applications with identical electrical mating pitch, position count, and mechanical mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can Molex 0901220765 be used as a direct replacement for Molex 0901220925?

A: Yes. Both parts are from the same C-Grid III 90122 series with identical connector type, contact configuration, pitch, position count, row spacing, mounting type, and termination method. The primary difference is packaging format (Bulk vs. Tray) and gold contact finish thickness (15.0µin vs. 30.0µin). The reduced finish thickness does not affect functional interchangeability in standard applications.

Q: What are the mechanical differences between the Molex and TE Connectivity parts?

A: Contact length specifications differ: Molex parts specify 0.266" mating contact length and 0.114" post length, while the TE Connectivity 5-103801-5 specifies 0.230" mating and 0.090" post length. Insulation height also varies slightly (0.242" vs. 0.238"). These dimensional variations are within acceptable tolerances for standard board-to-board and cable applications with 0.100" (2.54mm) pitch connectors.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts carry ROHS3 Compliant status with UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the significance of the contact finish thickness difference?

A: Contact finish thickness (30.0µin vs. 15.0µin gold) affects durability in high-cycle mating applications. The 30.0µin specification provides extended contact life. The 15.0µin variant (Molex 0901220765) is suitable for applications with moderate mating cycles and represents a cost-optimized alternative.

Q: Can these parts be used interchangeably in automotive applications?

A: Yes. All three parts list automotive applications within their specifications and maintain identical electrical and mechanical parameters required for automotive connector standards. Selection should be based on specific design requirements for contact finish durability and packaging format availability.
