Molex 0906350261 Equivalent & Substitute Parts

Part Overview

The Molex 0906350261 is a 26-position rectangular receptacle connector designed for IDC (Insulation Displacement Contact) termination on ribbon cables with 26-28 AWG wire gauge. This connector features gold-plated female socket contacts, a 0.100" (2.54mm) pitch in a 2-row configuration, and is rated for feed-through applications in free-hanging inline mounting.

The 0906350261 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0906350261 is determined by strict alignment of the following critical parameters:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 26 positions at 0.100" (2.54mm) pitch
Row Configuration: 2 rows with 0.100" (2.54mm) row spacing
Termination Method: IDC (Insulation Displacement Contact) for ribbon cable
Wire Compatibility: Ribbon cable, 26-28 AWG wire gauge
Contact Material: Gold plating for electrical performance and corrosion resistance
Mounting & Mechanical: Free-hanging inline configuration with feed-through capability
Regulatory Compliance: ROHS3 compliance and MSL 1 rating

The Adam Tech FCS-26-SG meets all critical substitution criteria. Both connectors share identical electrical and mechanical specifications for position count, pitch, row configuration, IDC termination, ribbon cable compatibility, gold contact finish, and regulatory compliance status.

Engineering Selection Recommendations

The Adam Tech FCS-26-SG is a direct functional equivalent to the obsolete Molex 0906350261. Both connectors satisfy identical electrical and mechanical requirements for 26-position IDC ribbon cable applications at 2.54mm pitch.

Selection between these parts should be based on:

Product Status: The FCS-26-SG maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete 0906350261.
Regulatory Compliance: Both parts are ROHS3 compliant and carry MSL 1 ratings, meeting identical environmental and handling requirements.
Mechanical Compatibility: The FCS-26-SG includes a polarizing key feature in addition to feed-through capability, providing enhanced mechanical alignment without compromising backward compatibility.
Inventory Availability: The FCS-26-SG is currently in stock with higher inventory levels, supporting immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can the Adam Tech FCS-26-SG directly replace the Molex 0906350261 in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications for position count, pitch, row configuration, IDC termination, ribbon cable compatibility, and contact finish. The FCS-26-SG's additional polarizing key feature enhances mechanical alignment and does not prevent compatibility with existing mating connectors.

Q: What is the significance of the polarizing key feature on the FCS-26-SG?

A: The polarizing key is a mechanical feature that prevents incorrect connector orientation during assembly. This feature is supplementary to the core electrical and mechanical specifications and does not affect electrical performance or compatibility with standard 26-position 2.54mm pitch ribbon cable applications.

Q: Are there any wire gauge limitations for the FCS-26-SG?

A: The Molex 0906350261 specifies 26-28 AWG wire gauge compatibility. While the FCS-26-SG datasheet does not explicitly state wire gauge limitations in the provided parameters, both connectors use identical IDC termination technology for ribbon cable, ensuring compatibility within the specified gauge range.

Q: Do both connectors meet the same regulatory and environmental standards?

A: Yes. Both the Molex 0906350261 and Adam Tech FCS-26-SG are ROHS3 compliant, carry MSL 1 (Unlimited) ratings, and are REACH unaffected. They meet identical regulatory and environmental handling requirements.

Q: What packaging format is the FCS-26-SG supplied in?

A: The Adam Tech FCS-26-SG is supplied in tray packaging, suitable for automated assembly and component handling processes.
