Molex 0894010210 Equivalent & Substitute Parts

Part Overview

The Molex 0894010210 is a rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications with 2 positions at 2.00mm pitch. This component features shrouded 4-wall construction with kinked pin solder termination and detent lock fastening. The part is classified as obsolete, making equivalent substitutes necessary for ongoing design requirements and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0894010210 is determined by the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm) - must match exactly
• Number of Positions: 2 - must match exactly
• Number of Rows: 1 - must match exactly
• Connector Type: Header - must match exactly
• Contact Type: Male Pin - must match exactly
• Mounting Type: Through Hole, Right Angle - must match exactly
• Style: Board to Cable/Wire - must match exactly
• Contact Material: Brass - must match exactly
• Material Flammability Rating: UL94 V-0 - must match exactly
• RoHS Status: ROHS3 Compliant - must match exactly

The substitute parts listed below meet all critical electrical and mechanical parameters. Variations in shrouding configuration (3-wall vs. 4-wall), termination method (press-fit vs. kinked pin), contact finish thickness, and operating temperature ranges are acceptable within the scope of functional equivalence for this connector category.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with full ROHS3 compliance and MSL 1 rating, providing superior procurement continuity compared to the obsolete Molex 0894010210.

TE Connectivity 440055-2 offers a 3-wall shrouded configuration with press-fit termination and operates within -25°C to 85°C. This part is suitable for general purpose, automotive, industrial, and medical applications with 3A current capacity at 250V.

Hirose DF3-2P-2DS(22) provides a 4-wall shrouded configuration matching the original Molex design, with press-fit termination and gold contact finish. This part operates across an extended temperature range of -55°C to 105°C with 3A current capacity. The push-pull fastening mechanism differs from the detent lock of the original part.

Selection between these substitutes depends on specific application requirements regarding shrouding geometry, fastening mechanism, contact finish, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 440055-2 directly replace the Molex 0894010210?

A: The TE Connectivity 440055-2 meets all critical electrical and mechanical parameters including pitch, position count, connector type, and contact material. The primary difference is the 3-wall shrouding versus the original 4-wall design. Compatibility depends on whether the reduced shrouding is acceptable for your application's mechanical constraints and EMI requirements.

Q: What is the difference between kinked pin and press-fit termination?

A: Kinked pin termination (original Molex part) uses a bent pin soldered directly to the PCB. Press-fit termination (both substitutes) uses a straight pin pressed into a plated through-hole. Press-fit termination typically provides improved mechanical reliability and is the current industry standard for through-hole connectors.

Q: Why does the Hirose part have gold contact finish while the others have tin?

A: Gold plating provides superior corrosion resistance and contact reliability in harsh environments. The Hirose DF3-2P-2DS(22) gold finish is compatible with the mating connector interface and does not affect electrical performance when mated with tin-plated contacts.

Q: Are there packaging differences between these parts?

A: The Molex 0894010210 packaging is not specified in available data. Both TE Connectivity 440055-2 and Hirose DF3-2P-2DS(22) are supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Which substitute is recommended for high-temperature applications?

A: The Hirose DF3-2P-2DS(22) operates from -55°C to 105°C, providing the widest temperature range. The TE Connectivity 440055-2 operates from -25°C to 85°C. Select based on your specific operating temperature requirements.

Q: Is the push-pull fastening on the Hirose part compatible with the original detent lock design?

A: The fastening mechanism is a mating interface feature. If your mating connector is designed for detent lock, the push-pull mechanism on the Hirose part will not provide the same locking behavior. Verify mating connector compatibility before selection.
