Amphenol ICC 50003-1300F Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50003-1300F is a 300-position high-density backplane connector receptacle with female sockets, designed for through-hole, right-angle PCB mounting. This connector features a 0.100" (2.54mm) pitch configuration across 4 rows and 75 columns with gold-plated contacts and integrated mating guide.

The 50003-1300F is classified as obsolete. Identification of equivalent and substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity where original components are no longer available through standard distribution channels.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 1-533939-0

The TE Connectivity AMP Connectors part 1-533939-0 is the direct functional equivalent for the obsolete Amphenol ICC 50003-1300F. Both connectors share identical electrical and mechanical specifications across all critical parameters: 300-position high-density configuration, 0.100" pitch, through-hole right-angle mounting, solder termination, and gold-plated contacts with mating guides.

The TE Connectivity substitute offers the following advantages:

• Active Product Status: The 1-533939-0 maintains active production status, ensuring ongoing availability and supply chain continuity.
• Enhanced Contact Finish: The substitute provides 50.0µin (1.27µm) gold plating thickness compared to the original 30.0µin (0.76µm), offering improved contact durability and wear resistance.
• Defined Operating Temperature Range: The substitute specifies an operating temperature range of -65°C to 125°C, providing explicit thermal performance parameters.
• Material Flammability Certification: The substitute carries UL94 V-0 flammability rating, documenting material compliance for safety-critical applications.

Both connectors maintain identical RoHS non-compliance status, MSL rating, export classification, and tariff codes. The substitute is suitable for direct replacement in legacy system maintenance and new designs requiring high-density backplane connectivity.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-533939-0 be used as a direct replacement for the Amphenol ICC 50003-1300F?

A: Yes. Both connectors are 300-position high-density receptacles with identical pitch (0.100"), mounting type (through-hole right angle), termination method (solder), and contact finish (gold). The connectors are mechanically and electrically interchangeable for PCB applications.

Q: What is the difference in contact finish thickness between these connectors?

A: The Amphenol ICC 50003-1300F specifies 30.0µin (0.76µm) gold plating, while the TE Connectivity 1-533939-0 provides 50.0µin (1.27µm) gold plating. The thicker plating on the substitute offers extended contact life and improved resistance to wear and corrosion.

Q: Why is the Amphenol ICC 50003-1300F classified as obsolete?

A: The 50003-1300F has reached end-of-life status in the manufacturer's product portfolio. The TE Connectivity 1-533939-0 represents the active equivalent for ongoing procurement and system support.

Q: Are there any compliance differences between these connectors?

A: Both connectors are RoHS non-compliant and carry identical export classification (EAR99) and tariff codes (8536.69.4040). The TE Connectivity substitute provides additional documentation through UL94 V-0 material flammability certification and defined operating temperature specifications (-65°C to 125°C).

Q: What is the MSL rating for these connectors?

A: Both connectors carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are the row and column configurations identical?

A: The Amphenol ICC 50003-1300F specifies 4 rows and 75 columns. The TE Connectivity 1-533939-0 confirms 4 rows with all 300 positions loaded. Both maintain the same high-density configuration and position count.
