Substitute Part Grouping Explanation

Substitution eligibility for the 77313-185-28LF is determined by the following critical parameters:

Connector Type & Configuration: Header with male pin contacts, 28 positions arranged in 2 rows
Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Termination: Through-hole mounting with solder termination
Electrical Performance: Current rating and operating temperature range
Compliance: RoHS compliance and flammability rating (UL94 V-0)

The 3M 929715-01-14-EU meets the core dimensional and functional requirements for board-to-board connectivity with identical pitch, position count, and row configuration. However, differences exist in contact length, current rating, operating temperature range, and contact finish specifications that must be evaluated for specific application requirements.

Engineering Selection Recommendations

Both the Amphenol ICC 77313-185-28LF and 3M 929715-01-14-EU are active products with RoHS compliance and UL94 V-0 flammability ratings. Selection between these parts must account for the following documented differences:

The 77313-185-28LF operates across -65°C to 130°C with a 3A per contact current rating and features a breakaway design. The 929715-01-14-EU operates across -40°C to 105°C with a 2.5A per contact current rating and does not include breakaway functionality.

Applications requiring the full temperature range of -65°C to 130°C or the higher 3A current rating per contact necessitate the 77313-185-28LF. Applications operating within -40°C to 105°C with current requirements not exceeding 2.5A per contact may utilize the 929715-01-14-EU as a substitute.

The 77313-185-28LF has a longer overall contact length (0.626" vs. 0.528"), which may affect mating depth and board layout considerations. Both connectors share identical pitch, row spacing, and insulation height specifications.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929715-01-14-EU be used as a direct replacement for the Amphenol ICC 77313-185-28LF?

A: Substitution is possible only when application requirements fall within the 929715-01-14-EU specifications. The substitute part has a reduced operating temperature range (-40°C to 105°C versus -65°C to 130°C) and lower current rating (2.5A versus 3A per contact). If your application requires the full temperature range or higher current capacity, the 77313-185-28LF is required.

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

A: The overall contact length differs: 77313-185-28LF is 0.626" (15.90mm) while 929715-01-14-EU is 0.528" (13.42mm). Mating contact length also differs: 0.413" (10.50mm) versus 0.318" (8.08mm). These differences may affect mating depth and PCB layout. Pitch, row spacing, and insulation height are identical at 0.100" (2.54mm).

Q: Are both parts RoHS compliant?

A: Yes, both the 77313-185-28LF and 929715-01-14-EU are RoHS compliant with UL94 V-0 flammability ratings and MSL 1 (Unlimited) moisture sensitivity levels.

Q: What is the difference in contact material between these parts?

A: The 77313-185-28LF uses Phosphor Bronze contacts, while the 929715-01-14-EU uses Copper Alloy contacts. Both feature gold plating on mating surfaces. The insulation material also differs: Thermoplastic versus Polycyclohexylenedimethylene Terephthalate (PCT).

Q: Does the 77313-185-28LF breakaway feature exist on the 929715-01-14-EU?

A: No. The 77313-185-28LF is specified as a breakaway header, while the 929715-01-14-EU is a standard header without breakaway functionality. This may affect assembly and application requirements.
