Equivalent & Substitute Parts for Molex 0026606021

Part Overview

The Molex 0026606021 is a rectangular connector header designed for through-hole mounting applications. This shrouded, single-wall header accommodates 2 positions at 0.156" (3.96mm) pitch and features male pins with solder termination and friction lock fastening. The connector is classified as Active product status and serves general purpose, industrial, automotive, medical, and telecommunications applications. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0026606021 is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 2
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Friction Lock
• Shrouding: Shrouded - 1 Wall
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The substitute parts identified—TE Connectivity AMP Connectors 3-644611-2 and 3-644615-2—satisfy all critical substitution parameters. Both parts are from the MTA-156 series and maintain functional and mechanical compatibility with the Molex KK396 series header. Variations in contact material (Copper Alloy vs. Brass), insulation material (Thermoplastic vs. Polyester), contact finish thickness, and operating temperature specifications do not preclude substitution when these parameters fall within acceptable design tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment with the Molex 0026606021. The TE Connectivity 3-644611-2 and 3-644615-2 are functionally equivalent for applications requiring 2-position, 0.156" pitch through-hole headers with solder termination and friction lock fastening.

The primary distinction between the substitute parts is the presence of a Board Guide feature in the 3-644615-2, which provides additional mechanical alignment during mating. Selection between the two TE Connectivity options depends on whether this feature is required for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-644611-2 or 3-644615-2 be used as direct replacements for the Molex 0026606021?

A: Yes. Both TE Connectivity parts satisfy all critical substitution parameters: identical pitch (0.156"), position count (2), row configuration (1), connector type (Header), contact type (Male Pin), mounting method (Through Hole), termination (Solder), fastening mechanism (Friction Lock), and shrouding (Shrouded - 1 Wall). All three parts carry UL94 V-0 flammability ratings and ROHS3 compliance.

Q: What are the differences between the two TE Connectivity substitute options?

A: The 3-644611-2 and 3-644615-2 are mechanically and electrically equivalent. The 3-644615-2 includes a Board Guide feature for enhanced alignment during mating, while the 3-644611-2 does not specify this feature. Both operate across -55°C to 105°C and carry 600VAC voltage ratings.

Q: Are there material differences between the Molex and TE Connectivity parts?

A: The Molex 0026606021 uses Brass contacts with Polyester insulation, while both TE Connectivity substitutes use Copper Alloy contacts with Thermoplastic insulation. Both insulation materials are glass-filled and UL94 V-0 rated. These material variations do not affect functional compatibility for standard applications.

Q: What is the inventory status of these parts?

A: Molex 0026606021 has 1110 pieces in stock. TE Connectivity 3-644611-2 has 5920 pieces in stock. TE Connectivity 3-644615-2 has 1733 pieces in stock.

Q: Are all three parts compliant with current regulatory standards?

A: Yes. All three parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements during storage or assembly.
