Molex 0022285121 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0022285121 is a vertical through-hole rectangular connector header with 12 positions at 2.54mm pitch, designed for board-to-board or cable applications. This unshrouded, breakaway header features kinked pin solder termination and is widely used in automotive, medical, telecommunications, and general-purpose applications. The part is currently active in production with full inventory availability. Equivalent and substitute parts are identified to provide design flexibility, supply chain alternatives, and compatibility options for applications requiring identical or functionally equivalent connector solutions.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022285121 is determined by strict alignment with the following core parameters:

• Connector Type: Header with breakaway or cuttable capability
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 12
• Number of Rows: 1
• Mounting Type: Through Hole
• Style: Board to Board or Cable
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts meet these core criteria. Variations in contact length, insulation height, contact finish, and operating temperature range do not preclude substitution when the application requirements fall within the specified ranges of the substitute part. All substitute parts maintain electrical and mechanical compatibility at the 2.54mm pitch standard and support identical PCB footprints.

Parameter Comparison

Engineering Selection Recommendations

All three parts—Molex 0022285121, TE Connectivity 1-826629-2, and Harwin M20-9991245—are active production components with ROHS3 compliance and UL94 V-0 flammability ratings. Selection among these parts should be based on application-specific requirements:

The Molex 0022285121 features kinked pin termination and is suitable for applications requiring robust mechanical retention during assembly. The TE Connectivity 1-826629-2 offers the widest operating temperature range (-65°C to 105°C) and highest current rating (5A), making it appropriate for demanding automotive and industrial environments. The Harwin M20-9991245 provides cuttable header capability, enabling custom position configurations and is rated for -40°C to 105°C operation with 3A per contact current capacity.

All parts maintain identical PCB footprints at 2.54mm pitch and support board-to-board or cable interconnection. Compliance certifications and moisture sensitivity levels are equivalent across all options. Selection should prioritize application temperature range, current requirements, and assembly methodology (breakaway versus cuttable configuration).

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-826629-2 be used as a direct replacement for the Molex 0022285121?

A: Yes. Both parts share identical pitch (2.54mm), position count (12), row configuration (1), mounting type (through hole), and connector style (board to board or cable). PCB footprints are compatible. Differences in contact length and insulation height do not affect electrical or mechanical compatibility at the connector interface.

Q: What is the primary difference between the Harwin M20-9991245 and the Molex 0022285121?

A: The Harwin part features cuttable header design, allowing individual positions to be separated post-manufacturing, whereas the Molex part uses breakaway design. Both maintain 2.54mm pitch and 12-position configuration. The Harwin part operates at -40°C to 105°C with 3A per contact rating, compared to the Molex part's unspecified operating temperature and current rating.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The Molex 0022285121, TE Connectivity 1-826629-2, and Harwin M20-9991245 are all ROHS3 compliant with UL94 V-0 flammability ratings and MSL 1 (Unlimited) moisture sensitivity levels.

Q: What is the impact of different contact finish materials on substitution?

A: The Molex part uses tin contact finish, while both TE Connectivity and Harwin parts use gold finish. Gold provides superior corrosion resistance and contact reliability in high-reliability applications. Tin finish is suitable for general-purpose applications with standard environmental conditions. Contact finish differences do not preclude substitution when application requirements are met by either finish type.

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

A: Yes. All three parts are rated for automotive applications and maintain UL94 V-0 compliance. The TE Connectivity 1-826629-2 offers the widest temperature range (-65°C to 105°C), making it optimal for automotive environments with extreme temperature exposure. The Molex and Harwin parts are also suitable for standard automotive temperature ranges.

Q: What are the current rating differences among the three parts?

A: The TE Connectivity 1-826629-2 is rated at 5A, the Harwin M20-9991245 at 3A per contact, and the Molex 0022285121 has an unspecified current rating. For applications requiring 5A capacity, the TE Connectivity part is the specified choice. For applications requiring 3A or less, all three parts are suitable.
