TE Connectivity AMP Connectors 2-5102321-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-5102321-3 is an active rectangular connector header designed for through-hole mounting applications. This 16-position, 2-row connector operates at 0.100" (2.54mm) pitch and supports board-to-cable/wire connections with solder termination. The connector features shrouded 4-wall construction with latch lock/eject hooks for secure mating. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate alternative suppliers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 2-5102321-3 are identified based on strict equivalence of core electrical and mechanical parameters. The substitution criteria are:

Primary Matching Parameters:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 16
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Contact shape: Square
• Style: Board to Cable/Wire
• Material flammability rating: UL94 V-0
• RoHS compliance: RoHS Compliant
• Moisture sensitivity level: 1 (Unlimited)

The Amphenol ICC (FCI) part number 71918-116LF meets all primary matching parameters and qualifies as a direct substitute. Both connectors share identical mating pitch, row configuration, mounting methodology, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 2-5102321-3 and Amphenol ICC 71918-116LF are active products with identical regulatory compliance profiles. Both connectors carry RoHS Compliant status, UL94 V-0 flammability rating, and unlimited moisture sensitivity level (MSL 1). Both are classified under ECCN EAR99 and HTSUS code 8536.69.4040.

The primary distinction between these parts is packaging format: the TE Connectivity part is supplied in trays, while the Amphenol ICC part is supplied in tubes. This difference affects inventory management and handling procedures but does not impact electrical or mechanical performance.

Selection between these parts should be based on:

1. Availability and lead time requirements - The Amphenol ICC 71918-116LF currently maintains significantly higher inventory levels (343,780 pieces versus 1,098 pieces).
2. Packaging compatibility - Verify that the receiving system accommodates either tray or tube packaging formats.
3. Existing supply chain relationships - Evaluate preferred supplier agreements and established procurement channels.
4. Contact geometry specifications - Minor variations exist in contact length dimensions; verify PCB design accommodates both options.

Frequently Asked Questions (FAQ)

Q: Are the TE Connectivity 2-5102321-3 and Amphenol ICC 71918-116LF electrically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.100"), row spacing (0.100"), number of positions (16), contact type (male pin), and contact finish specifications (30.0µin gold mating surface). Both support the same voltage and current applications within their respective ratings.

Q: What are the physical differences between these connectors?

A: The primary physical differences are contact length dimensions and insulation height. The TE Connectivity part has a contact mating length of 0.240" (6.10mm) and insulation height of 0.549" (13.94mm). The Amphenol ICC part has a contact mating length of 0.228" (5.80mm) and insulation height of 0.685" (17.40mm). These variations require verification against PCB design specifications to ensure proper fit and mating depth.

Q: Can I use these connectors interchangeably on the same PCB?

A: Interchangeability depends on PCB design specifications. The difference in insulation height (0.549" versus 0.685") and contact mating length (0.240" versus 0.228") may affect board layout, mating depth, and clearance requirements. PCB design must accommodate the specific connector geometry selected.

Q: What is the difference between tray and tube packaging?

A: Tray packaging (TE Connectivity) organizes connectors in flat trays suitable for automated pick-and-place equipment. Tube packaging (Amphenol ICC) organizes connectors in cylindrical tubes suitable for manual handling and bulk storage. Packaging selection affects receiving procedures, storage requirements, and integration with assembly line equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both the TE Connectivity 2-5102321-3 and Amphenol ICC 71918-116LF are RoHS Compliant and carry identical regulatory certifications including UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: What is the current rating for these connectors?

A: The TE Connectivity 2-5102321-3 is rated at 1A per contact. Current rating information for the Amphenol ICC 71918-116LF is not provided in the available specifications.

Q: What voltage rating applies to these connectors?

A: The TE Connectivity 2-5102321-3 is rated at 250VAC. Voltage rating information for the Amphenol ICC 71918-116LF is not provided in the available specifications.
