Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0015911501 is determined by strict alignment of the following critical parameters:

Connector Type: Header, Breakaway configuration
Contact Type: Male Pin
Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 50
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Surface Mount
Termination: Solder
Fastening Type: Push-Pull
Contact Shape: Square
Shrouding: Unshrouded
Material Flammability Rating: UL94 V-0
Insulation Color: Black
Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts (Amphenol ICC FCI 95278-101-50LF and 95278-101B50LF) meet all critical electrical and mechanical parameters. Variations in contact finish material, contact finish thickness, insulation material composition, and packaging format do not affect functional interchangeability in applications where the core mating interface and board-to-board connectivity requirements are identical.

Engineering Selection Recommendations

All three connectors maintain Active product status with UL94 V-0 flammability certification and MSL 1 rating, confirming suitability for standard industrial and commercial applications. The Amphenol ICC BERGSTIK® series substitutes (95278-101-50LF and 95278-101B50LF) are RoHS compliant and functionally equivalent for board-to-board 50-position 2.54mm pitch header applications.

Selection between the two Amphenol ICC options depends on packaging requirements: the 95278-101-50LF is supplied in Bulk packaging, while the 95278-101B50LF is supplied in Tube packaging with Pick and Place feature designation. Both maintain identical electrical and mechanical interface specifications.

Frequently Asked Questions (FAQ)

Q: Can Amphenol ICC 95278-101-50LF and 95278-101B50LF be used interchangeably with Molex 0015911501?

A: Yes. Both Amphenol ICC parts meet the critical substitution parameters: 50-position, 2-row, 2.54mm pitch, surface mount, solder termination, push-pull fastening, and UL94 V-0 flammability rating. Functional compatibility is confirmed for board-to-board applications.

Q: What are the differences between the two Amphenol ICC substitute parts?

A: The primary difference is packaging format. The 95278-101-50LF is supplied in Bulk packaging, while the 95278-101B50LF is supplied in Tube packaging and includes Pick and Place feature designation for automated assembly compatibility.

Q: Does the contact finish difference (Tin vs. Gold) affect substitution eligibility?

A: Contact finish variation does not affect functional interchangeability for standard board-to-board mating applications. The Amphenol ICC parts feature Gold GXT™ finish on mating contacts compared to Tin finish on the Molex original. Both finishes provide adequate electrical conductivity and corrosion resistance for the specified applications.

Q: Are there differences in contact length between the main part and substitutes?

A: The Molex 0015911501 specifies 0.240" (6.10mm) mating contact length, while both Amphenol ICC substitutes specify 0.232" (5.90mm). This 0.008" (0.20mm) difference is within tolerance for standard board-to-board connector mating and does not compromise electrical or mechanical performance.

Q: What is the significance of the insulation height difference?

A: The Molex original specifies 0.090" (2.29mm) insulation height, while Amphenol ICC substitutes specify 0.100" (2.54mm). This difference reflects design variation between manufacturers but does not affect functional compatibility in applications where the connector footprint and mating interface are the primary design constraints.

Q: Are all three parts RoHS compliant?

A: Yes. The Molex 0015911501 is RoHS3 compliant. Both Amphenol ICC substitutes are RoHS compliant. All three parts meet regulatory requirements for lead-free and restricted substance compliance.
