Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0015910408 is determined by strict alignment of the following parameters:

Connector configuration: 40 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
Mounting and termination: Surface mount with solder termination
Fastening mechanism: Push-pull fastening type
Contact geometry: Male pin, square contact shape
Compliance: UL94 V-0 flammability rating, RoHS compliance, MSL 1

All five substitute parts meet these core requirements. Variations exist in contact finish specifications (gold vs. tin), contact length, insulation height, contact material composition, and packaging format. These variations are permissible within the substitution scope as they do not affect the fundamental electrical and mechanical interface compatibility.

Engineering Selection Recommendations

All five Amphenol ICC (FCI) substitute parts are active production components with RoHS compliance and MSL 1 rating, meeting the core compliance requirements of the Molex 0015910408.

BERGSTIK® II Series (95157-140LF, 95157-240LF, 95157-440LF): These parts differ primarily in contact finish specifications. The 95157-140LF and 95157-240LF provide gold-plated contacts with varying thickness (30.0µin and 15.0µin respectively), while the 95157-440LF features tin plating at 100.0µin thickness. Operating temperature range extends to 130°C. Contact length is 0.230" (5.84mm), shorter than the original part's 0.320" (8.13mm).

BERGSTIK® Series (95278-101-40LF, 95278-401A40LF, 95278-401B40LF): These parts feature gold GXT™ or tin contact finishes with contact length of 0.232" (5.90mm). Operating temperature range is -65°C to 125°C. The 95278-401A40LF is supplied in cut tape format suitable for automated pick-and-place assembly, while 95278-401B40LF is supplied in tube format matching the original packaging. The 95278-101-40LF is supplied in bulk format.

Selection between substitute parts depends on specific application requirements for contact finish (gold vs. tin), packaging format (bulk, cut tape, or tube), and thermal operating range (125°C vs. 130°C maximum).

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0015910408 with any of the listed Amphenol parts?

A: Yes. All listed Amphenol parts maintain the same 40-position, 2-row configuration at 0.100" (2.54mm) pitch with identical mounting type, termination method, and fastening mechanism. They are electrically and mechanically compatible for board-to-board applications.

Q: What is the difference between the BERGSTIK® II and BERGSTIK® series substitutes?

A: Both series meet the core substitution criteria. The BERGSTIK® II series (95157 base number) offers operating temperatures to 130°C, while the BERGSTIK® series (95278 base number) operates to 125°C. Contact length differs slightly: BERGSTIK® II at 0.230" (5.84mm) versus BERGSTIK® at 0.232" (5.90mm). Both are functionally equivalent for standard applications.

Q: Why is the contact length different between the original part and substitutes?

A: The Molex 0015910408 has a contact length of 0.320" (8.13mm), while Amphenol substitutes range from 0.230" to 0.232" (5.84mm to 5.90mm). This difference is within the scope of substitution as it does not affect the mating interface or electrical performance. Verify board layout compatibility if contact length is critical to your application.

Q: What packaging options are available for these substitutes?

A: The Amphenol substitutes are supplied in three formats: bulk (95157-140LF, 95157-240LF, 95157-440LF, 95278-101-40LF), cut tape for automated assembly (95278-401A40LF), and tube (95278-401B40LF). Select based on your manufacturing process requirements.

Q: Does contact finish affect electrical performance?

A: Contact finish (gold vs. tin) and thickness do not affect the fundamental electrical interface. Gold finishes provide enhanced corrosion resistance in certain environments, while tin finishes are suitable for standard applications. Selection depends on environmental exposure and application-specific requirements.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed Amphenol substitutes are RoHS compliant. The original Molex part is ROHS3 compliant, while Amphenol substitutes are RoHS compliant. Both certifications meet current regulatory requirements.
