Molex 0039512263 Equivalent & Substitute Parts

Part Overview

The Molex 0039512263 is a 26-position rectangular receptacle connector designed for IDC (Insulation Displacement Contact) termination with ribbon cable. This connector features a dual-row configuration with 0.100" pitch spacing, gold-plated contacts, and polarizing key functionality. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0039512263 is determined by strict alignment of the following critical parameters:

• Connector Configuration: 26-position receptacle with dual-row layout
• Contact Pitch and Spacing: 0.100" (2.54mm) pitch and row spacing
• Termination Method: IDC cable termination for ribbon cable
• Wire Gauge Compatibility: 26-28 AWG support
• Mechanical Features: Feed-through design with polarizing key
• Contact Material: Gold plating for signal integrity

The TE Connectivity AMP Connectors part 1658622-6 meets all substitution criteria. While contact geometry differs (forked vs. socket), both designs accommodate IDC termination within the specified wire gauge range and maintain electrical and mechanical compatibility within the connector family.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1658622-6 is the designated substitute for the obsolete Molex 0039512263. Selection rationale is based on the following factors:

Product Status: The Molex part is obsolete, while the TE Connectivity alternative maintains active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: The TE Connectivity 1658622-6 is RoHS compliant, meeting current environmental and regulatory requirements. The original Molex part is non-compliant, making the substitute preferable for new designs and compliance-sensitive applications.

Functional Equivalence: Both connectors share identical electrical and mechanical specifications across all critical parameters: 26-position configuration, 0.100" pitch, IDC termination, 26-28 AWG wire gauge support, and polarizing key features.

Contact Material: The TE Connectivity part offers gold or gold-palladium finish options with 30.0µin thickness, compared to the Molex gold finish at 3.94µin thickness. The thicker plating on the substitute provides enhanced durability and contact reliability.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1658622-6 directly replace the Molex 0039512263 in existing assemblies?

A: Yes. Both connectors share identical pitch, row spacing, position count, and IDC termination method. The polarizing key design ensures correct orientation. Physical and electrical compatibility is maintained across all specified parameters.

Q: What is the difference between socket and forked contact designs in these connectors?

A: Socket contacts (Molex) and forked contacts (TE Connectivity) are both IDC-compatible designs. The forked contact geometry in the TE Connectivity part provides alternative contact engagement characteristics while maintaining the same wire gauge range (26-28 AWG) and termination method.

Q: Does the thicker contact plating on the TE Connectivity part affect compatibility?

A: No. The 30.0µin gold-palladium plating on the TE Connectivity 1658622-6 is thicker than the 3.94µin gold plating on the Molex part, which enhances contact durability and signal integrity without affecting mechanical or electrical compatibility.

Q: Is the TE Connectivity part suitable for new designs?

A: Yes. The TE Connectivity 1658622-6 is active production status and RoHS compliant, making it the appropriate choice for new designs. The obsolete Molex part should not be specified for new applications.

Q: Are there any packaging differences between these parts?

A: The Molex part is listed with unspecified packaging, while the TE Connectivity substitute is supplied in bulk packaging. Confirm packaging requirements with your procurement department for order fulfillment.
