Molex 0015911404 Rectangular Connector Header – Equivalent & Substitute Parts

Part Overview

The Molex 0015911404 is a surface mount rectangular connector header designed for board-to-board or cable applications. This 40-position, 2-row header with 0.100" (2.54mm) pitch is classified as an active product and is widely used in automotive, medical, telecommunications, and general-purpose applications. The connector features an unshrouded design with solder termination and push-pull fastening. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, manage inventory across multiple vendors, and maintain design compatibility when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0015911404 is determined by strict alignment of the following critical parameters:

• Connector Configuration: 40 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
• Mounting and Termination: Surface mount with solder termination
• Connector Type: Header with breakaway capability and push-pull fastening
• Contact Specification: Male pin contacts with tin finish
• Shrouding: Unshrouded design
• Compliance: UL94 V-0 flammability rating, RoHS compliance, and MSL 1 rating

The Amphenol ICC (FCI) part number 95278-402B40LF meets all these critical parameters and qualifies as a direct substitute. Both parts share identical mating pitch, position count, row configuration, surface mount design, and solder termination. Both are active products with equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0015911404 and Amphenol ICC 95278-402B40LF are active products with equivalent compliance profiles. Both meet UL94 V-0 flammability requirements, RoHS compliance standards, and MSL 1 moisture sensitivity ratings. The critical mating parameters—pitch, position count, row configuration, and termination method—are identical between the two parts.

Minor dimensional variations exist in contact length and insulation height; however, these differences fall within acceptable tolerances for standard 0.100" pitch header applications. The Amphenol ICC part provides specified operating temperature range (-65°C ~ 125°C) and current rating (3A per contact), whereas the Molex part does not specify these values in the provided data.

Selection between these parts should be based on supply availability, lead time requirements, and established vendor relationships. Both parts are suitable for automotive, medical, telecommunications, and general-purpose applications requiring surface mount 40-position headers with 2.54mm pitch.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 95278-402B40LF be used as a direct replacement for the Molex 0015911404?

A: Yes. Both parts share identical mating pitch (0.100" / 2.54mm), position count (40), row configuration (2 rows), mounting type (surface mount), termination method (solder), and fastening mechanism (push-pull). Both are unshrouded headers with tin-plated male pin contacts and equivalent compliance certifications.

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

A: The primary differences are contact material (Copper Alloy vs. Phosphor Bronze), insulation material (LCP glass-filled vs. Thermoplastic), contact length (0.320" vs. 0.315"), and insulation height (0.090" vs. 0.100"). The Amphenol ICC part specifies operating temperature and current rating, while the Molex part does not provide these values in the available data.

Q: Are there any PCB layout considerations when switching between these parts?

A: The mating pitch and row spacing are identical (0.100" / 2.54mm), so PCB footprints are compatible. Minor differences in contact length and insulation height should be verified against your specific board design and mating connector specifications to ensure proper engagement and clearance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are UL94 V-0 rated, RoHS compliant, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are active products from established manufacturers.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant?

A: ROHS3 refers to the third iteration of RoHS regulations (Directive 2015/863/EU), which includes additional restricted substances. RoHS Compliant indicates adherence to RoHS standards. Both designations confirm compliance with current RoHS requirements; the specific version designation reflects regulatory updates over time.
