Substitute Part Grouping Explanation

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

Connector Type & Contact Configuration: Receptacle, female socket, 2-position
Pitch & Spacing: 0.100" (2.54mm) mating pitch, single row
Mounting & Termination: Through-hole PCB mounting with solder termination
Fastening Mechanism: Push-pull fastening type
Physical Dimensions: Insulation height 0.335" (8.51mm), contact post length 0.114" (2.90mm)
Contact Material & Shape: Phosphor bronze, square contact shape

The three substitute parts (75915-302LF, 75915-402LF, 75915-802LF) from Amphenol ICC (FCI) Dubox™ series meet all critical mechanical and electrical compatibility requirements. Variations in contact finish (gold vs. tin) and contact finish thickness represent acceptable substitutions based on application requirements and compliance certifications.

Engineering Selection Recommendations

All three Amphenol ICC (FCI) substitute parts maintain active product status and RoHS compliance, ensuring long-term availability and regulatory alignment with the original Molex 0901471302.

75915-302LF: Provides the closest electrical match with identical gold contact finish thickness (30.0µin) and mating contact specifications. Suitable for applications requiring consistent contact resistance and reliability performance equivalent to the original part.

75915-402LF: Offers tin-plated mating contacts with increased finish thickness (78.7µin), providing enhanced corrosion resistance in industrial and telecommunications environments. Contact finish difference requires evaluation against specific application requirements.

75915-802LF: Maintains gold contact finish with reduced thickness (15.0µin), suitable for cost-optimized designs where contact durability requirements align with thinner plating specifications.

All substitutes are certified to UL94 V-0 flammability rating, exceeding the original part's material specification. Packaging format differs (bulk vs. tube), requiring consideration of procurement and inventory management workflows.

Frequently Asked Questions (FAQ)

Q: Are these parts mechanically interchangeable with the Molex 0901471302?

A: Yes. All substitute parts share identical pitch (0.100"), insulation height (0.335"), contact post length (0.114"), and push-pull fastening mechanism. Through-hole mounting footprints are compatible.

Q: What is the difference between the three substitute options?

A: The primary differences are contact finish material and thickness. 75915-302LF uses gold (30.0µin), 75915-402LF uses tin (78.7µin), and 75915-802LF uses gold (15.0µin). All maintain phosphor bronze contact material and square contact geometry.

Q: Can I use the tin-plated 75915-402LF in place of the gold-plated original?

A: Tin plating provides different contact resistance and corrosion characteristics. Selection depends on application environment and electrical performance requirements. Both are RoHS compliant and rated for identical pitch and mounting specifications.

Q: What is the impact of packaging format differences?

A: The original part is supplied in tube packaging; substitutes are supplied in bulk packaging. This affects handling, storage, and procurement processes but does not impact electrical or mechanical performance.

Q: Are all substitutes rated for the same operating temperature range?

A: The original Molex part specifies -55°C to 105°C operating temperature. Substitute part datasheets do not specify operating temperature limits in the provided data. Verify operating temperature requirements with manufacturer documentation before final selection.

Q: Do these parts have the same current and voltage ratings?

A: The original Molex 0901471302 is rated for 3A at 350V. Current and voltage ratings are not specified in the provided data for substitute parts. Verify electrical ratings with manufacturer documentation for applications requiring specific power handling specifications.
