Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 77313-185-26LF is determined by strict alignment of the following critical parameters:

Connector positioning and pitch: 26 positions, 2 rows, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing
Contact configuration: Male pin, square contact shape, solder termination
Mounting and fastening: Through-hole mounting with push-pull fastening
Electrical performance: Current rating and operating temperature range
Compliance: RoHS compliance and UL94 V-0 flammability rating

The 3M 929715-01-13-EU meets the core positional, pitch, contact type, and mounting requirements. However, variations exist in contact length, insulation material, operating temperature range, and current rating. These differences must be evaluated against specific application requirements.

Engineering Selection Recommendations

Both the Amphenol ICC 77313-185-26LF and 3M 929715-01-13-EU are active products with RoHS compliance and UL94 V-0 flammability certification. Selection between these parts depends on application-specific requirements:

The Amphenol ICC 77313-185-26LF supports an extended operating temperature range (-65°C to 130°C) and higher current rating (3A per contact) compared to the 3M substitute. The Amphenol part features a longer overall contact length (0.626" vs. 0.528") and tin-plated posts, while the 3M part uses gold-plated posts and polycyclohexylenedimethylene terephthalate (PCT) insulation material.

Applications requiring the full temperature range or higher current capacity should retain the Amphenol ICC part. Applications operating within -40°C to 105°C and requiring 2.5A or less per contact may use the 3M 929715-01-13-EU as a substitute, provided PCB layout accommodates the shorter contact length and post finish differences.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929715-01-13-EU directly replace the Amphenol ICC 77313-185-26LF?

A: Direct replacement is possible only if the application operates within the 3M part's temperature range (-40°C to 105°C), requires no more than 2.5A per contact, and the PCB design accommodates the shorter overall contact length (0.528" vs. 0.626"). The different post finishes (gold vs. tin) and insulation materials must also be compatible with the application's soldering and environmental requirements.

Q: What are the key differences in contact specifications?

A: The Amphenol ICC part has a mating contact length of 0.413" (10.50mm) with tin-plated posts, while the 3M part has a mating contact length of 0.318" (8.08mm) with gold-plated posts. These differences affect insertion depth, contact engagement, and corrosion resistance characteristics.

Q: Are both parts RoHS compliant?

A: Yes, both the Amphenol ICC 77313-185-26LF and 3M 929715-01-13-EU are RoHS compliant with UL94 V-0 flammability ratings and MSL 1 (unlimited) moisture sensitivity levels.

Q: What packaging formats are available?

A: The Amphenol ICC 77313-185-26LF is supplied in bag packaging, while the 3M 929715-01-13-EU is supplied in bulk packaging. Packaging format may affect handling, storage, and inventory management procedures.

Q: How do the operating temperature ranges differ?

A: The Amphenol ICC part operates from -65°C to 130°C, providing a wider temperature envelope. The 3M substitute operates from -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must use the Amphenol ICC part.
