Amphenol ICC 77313-452-20LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77313-452-20LF is an active rectangular connector header designed for through-hole board-to-board applications. This vertical 20-position connector operates at 0.100" (2.54mm) pitch and supports 3A per contact with a temperature range of -65°C to 130°C. Finding equivalent substitute parts becomes necessary when managing supply chain continuity, optimizing inventory costs, or accommodating regional packaging requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 77313-452-20LF is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins, 20 positions in 2 rows
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Electrical Performance: Current rating and operating temperature range
• Compliance: RoHS compliance and flammability rating (UL94 V-0)

The three 3M 929715 series parts listed below meet these core substitution criteria. However, variations in contact finish, contact length, insulation material, and current rating exist and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All three 3M 929715 series substitute parts maintain active product status and RoHS compliance with UL94 V-0 flammability certification, ensuring regulatory alignment with the primary 77313-452-20LF connector.

Critical Differences Requiring Application Evaluation:

The 77313-452-20LF operates at 3A per contact with an extended temperature range of -65°C to 130°C. The 3M 929715 series parts are rated at 2.5A per contact with a narrower operating range of -40°C to 105°C. Applications requiring the full current or temperature specifications of the Amphenol ICC part cannot use these 3M substitutes without circuit redesign.

Contact finish differs significantly: the 77313-452-20LF uses tin plating (2.00µm), while all 3M substitutes use gold plating (0.25µm). Gold-plated contacts provide superior corrosion resistance and lower contact resistance, beneficial for low-signal applications. Tin plating is suitable for standard industrial applications.

Post length varies across the 3M lineup. The 929715-01-10-EU and 929715-01-10-I variants feature 0.110" (2.79mm) posts, while the 929715-03-10-I extends to 0.410" (10.41mm). Post length selection depends on PCB thickness and solder joint requirements.

Insulation material differs: the 77313-452-20LF uses thermoplastic, while 929715-01-10-EU uses polycyclohexylenedimethylene terephthalate (PCT), and both 929715-01-10-I and 929715-03-10-I use polybutylene terephthalate (PBT) with glass filler. These materials provide equivalent mechanical and thermal performance for standard applications.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929715 series parts directly replace the Amphenol ICC 77313-452-20LF in all applications?

A: Direct replacement is possible only when application current requirements do not exceed 2.5A per contact and operating temperature remains within -40°C to 105°C. Applications requiring 3A per contact or the extended -65°C lower temperature limit require the original Amphenol ICC part or circuit redesign.

Q: What is the significance of the contact finish difference between tin and gold plating?

A: Tin plating (2.00µm on the 77313-452-20LF) provides cost-effective corrosion protection suitable for standard industrial environments. Gold plating (0.25µm on 3M parts) offers superior corrosion resistance and lower contact resistance, making it preferable for low-signal or high-reliability applications. Both finishes are suitable for standard solder termination.

Q: How do the three 3M 929715 variants differ, and which should I select?

A: The 929715-01-10-EU and 929715-01-10-I differ only in insulation material (PCT versus glass-filled PBT) and packaging format. The 929715-03-10-I features an extended 0.410" (10.41mm) post length compared to 0.110" (2.79mm) on the other variants. Select based on PCB thickness requirements and regional packaging availability.

Q: Are all substitute parts RoHS compliant and UL94 V-0 rated?

A: Yes. All three 3M 929715 series parts maintain RoHS compliance and UL94 V-0 flammability certification, matching the regulatory status of the Amphenol ICC 77313-452-20LF.

Q: What packaging formats are available for these parts?

A: The Amphenol ICC 77313-452-20LF is supplied in bag packaging. The 3M 929715 series parts are supplied in bulk packaging, which may affect inventory management and handling procedures.
