Molex 0878344411 Equivalent & Substitute Parts

Part Overview

The Molex 0878344411 is an active rectangular connector header designed for through-hole mounting applications. This shrouded 44-position connector with 2.54mm pitch serves board-to-cable/wire interconnection in automotive, medical, telecommunications, and general-purpose applications. The connector features male pins with gold-plated mating contacts and tin-plated posts, housed in a glass-filled polyamide insulation body with UL94 V-0 flammability rating.

Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component flexibility while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The Amphenol ICC (FCI) part number 66506-246 qualifies as a substitute for the Molex 0878344411 based on the following critical parameters:

Matching Parameters:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 44
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening type: Push-Pull
• Contact shape: Square
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)
• ECCN: EAR99

These parameters establish mechanical and electrical interchangeability for board-level interconnection applications. Both connectors support identical mating pitch, row configuration, and mounting methodology, enabling direct functional substitution in circuit board designs.

Parameter Comparison

Engineering Selection Recommendations

Both connectors maintain active product status and share identical mechanical and electrical specifications for mating pitch, row configuration, and mounting methodology. The Molex 0878344411 holds ROHS3 compliance and REACH unaffected status, making it the preferred selection for applications subject to European regulatory requirements.

The Amphenol ICC 66506-246 is RoHS non-compliant and REACH affected. Selection of this substitute requires verification that the application environment and regulatory jurisdiction do not mandate RoHS3 or REACH compliance. Both connectors achieve UL94 V-0 flammability rating and MSL 1 classification, supporting equivalent reliability in standard operating conditions.

Contact length variations between the two parts (mating contact 0.240" versus 0.230", post contact 0.135" versus 0.150") fall within acceptable tolerances for standard through-hole board interconnection but should be evaluated for specific board thickness and connector stack-height requirements.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0878344411 and Amphenol ICC 66506-246 mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.100"), row spacing (0.100"), number of positions (44), number of rows (2), shrouding configuration (4-wall), and mounting type (through-hole). They are mechanically interchangeable for standard board-to-cable/wire interconnection applications.

Q: What are the key differences between these two connectors?

A: Primary differences include contact material (Copper Alloy versus Phosphor Bronze), insulation material (Polyamide versus Polyester), insulation color (Beige versus Black), contact length specifications (minor variations in mating and post lengths), and regulatory compliance status (ROHS3 compliant versus RoHS non-compliant; REACH unaffected versus REACH affected).

Q: Can I use the Amphenol ICC 66506-246 in applications requiring RoHS3 compliance?

A: No. The Amphenol ICC 66506-246 is RoHS non-compliant. Applications subject to RoHS3 requirements must use the Molex 0878344411 or identify an alternative RoHS3-compliant substitute.

Q: Do contact length differences affect compatibility?

A: Contact length variations are minor (0.010" mating contact difference, 0.015" post contact difference) and typically fall within acceptable tolerances for standard through-hole applications. However, applications with specific board thickness or connector stack-height constraints should evaluate these dimensions against design requirements.

Q: What is the significance of the different contact materials?

A: The Molex connector uses Copper Alloy contacts while the Amphenol ICC connector uses Phosphor Bronze. Both materials support gold plating for mating surfaces and provide equivalent electrical conductivity for standard interconnection applications. Material selection does not affect functional interchangeability for typical board-level applications.

Q: Are both connectors suitable for automotive applications?

A: The Molex 0878344411 explicitly lists automotive applications. The Amphenol ICC 66506-246 does not specify applications in the provided data. Automotive application requirements should be verified with the Amphenol ICC manufacturer before substitution.
