Molex 0441300004 Equivalent & Substitute Parts

Part Overview

The Molex 0441300004 is a rectangular connector header designed for through-hole, right-angle board-to-cable applications. This shrouded 6-position connector operates at a 0.165" (4.20mm) pitch and features male pin contacts with solder termination. The part is currently active in production with 926 units in stock. Equivalent parts are identified when they maintain the same electrical mating characteristics, physical pitch, position count, and mounting orientation while meeting equivalent compliance standards.

Key Parameters

Substitute Part Grouping Explanation

The Samtec Inc. IPBT-103-H1-T-D-RA qualifies as an equivalent substitute based on the following critical parameters:

• Identical mating pitch of 0.165" (4.20mm)
• Matching 6-position, 2-row configuration
• Equivalent through-hole, right-angle mounting orientation
• Identical shrouded 4-wall design
• Solder termination with locking ramp fastening
• Matching UL94 V-0 flammability rating
• ROHS3 compliance maintained
• Both parts support board-to-cable connectivity

Substitution is valid where these core parameters align, enabling direct functional replacement in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0441300004 and Samtec IPBT-103-H1-T-D-RA maintain active production status and full ROHS3 compliance. Selection between these parts should be based on:

• Availability and lead time requirements
• Packaging format preference (Molex supplied in Tray; Samtec in Bulk)
• Insulation material compatibility (Molex uses Polyamide PA66; Samtec uses Liquid Crystal Polymer LCP)
• Operating temperature range (Samtec specifies -55°C ~ 105°C; Molex does not specify)
• Voltage rating requirements (Samtec rated 400VAC, 565VDC; Molex does not specify)

Both parts satisfy equivalent rectangular connector rectangular connectors 6-position 4.2mm pitch applications with identical mechanical and electrical mating interfaces.

Frequently Asked Questions (FAQ)

Q: What makes the Samtec IPBT-103-H1-T-D-RA a valid substitute for the Molex 0441300004?

A: Both connectors share identical mating pitch (0.165" / 4.20mm), position count (6), row configuration (2), mounting style (through-hole right-angle), shrouding design (4-wall), and termination method (solder with locking ramp). These parameters define functional compatibility in board-to-cable applications.

Q: Are there differences in insulation material between these parts?

A: Yes. The Molex 0441300004 uses Polyamide (PA66) insulation, while the Samtec IPBT-103-H1-T-D-RA uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements. Material selection should align with application thermal and chemical exposure conditions.

Q: What is the difference in packaging between these two parts?

A: The Molex part is supplied in Tray packaging, while the Samtec equivalent is supplied in Bulk packaging. This affects handling, storage, and inventory management but does not impact electrical or mechanical performance.

Q: Does the Samtec part provide additional operating specifications?

A: The Samtec IPBT-103-H1-T-D-RA specifies an operating temperature range of -55°C ~ 105°C and voltage ratings of 400VAC and 565VDC. The Molex 0441300004 does not provide these specifications in the available data. Applications requiring defined temperature or voltage performance should reference the Samtec datasheet.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, provided the mating connector and PCB layout accommodate the physical dimensions of the substitute part. The Samtec part has a slightly larger insulation height (0.424" vs 0.378") and different contact post length (0.147" vs unspecified). Verify PCB clearance and mating connector compatibility before implementation.
