TE Connectivity 1-103673-3 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-103673-3 is a rectangular connector header classified as a through-hole, right-angle mounted component with 14 positions at 2.54mm pitch. This connector is designed for board-to-board or cable applications and features shrouded 4-wall construction with solder termination. The part maintains Active product status and is suitable for automotive, general purpose, medical, and telecommunications applications. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or application-specific compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The 1-103673-3 and 6-103673-3 are classified as direct substitutes based on the following criteria:

Critical Matching Parameters:

• Connector type, contact type, and mating pitch (0.100" / 2.54mm)
• Number of positions (14) and row configuration (1 row)
• Mounting method (through hole, right angle) and shrouding style (4 wall)
• Termination method (solder) and contact geometry (square shape)
• Contact length specifications for both mating and post dimensions
• Insulation height and material composition
• Operating temperature range (-65°C ~ 105°C)
• Current rating (3A) and flammability rating (UL94 V-0)
• Fastening mechanism (latch holder) and keying features

Both parts belong to the AMPMODU MTE series and maintain identical mechanical interfaces and electrical performance characteristics. The primary distinction between these parts relates to post-termination finish specification and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 1-103673-3 and 6-103673-3 are functionally equivalent rectangular connector headers suitable for direct substitution in applications requiring 14-position, 2.54mm pitch through-hole right-angle headers with solder termination.

1-103673-3 Selection Criteria:

• Applications where tin-lead post finish is specified or required
• Designs with no specific RoHS compliance mandate
• Legacy system integration or retrofit applications
• Current inventory availability: 795 pieces

6-103673-3 Selection Criteria:

• Applications requiring ROHS3 compliance certification
• New designs targeting modern regulatory standards
• Tin post finish specification compatibility
• Higher inventory availability: 1,823 pieces
• Recommended for new product development and long-term supply chain stability

Both parts maintain identical electrical performance, mechanical interface compatibility, and thermal operating characteristics. The selection between these parts should be based on regulatory compliance requirements and post-termination finish specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Are the 1-103673-3 and 6-103673-3 mechanically interchangeable?

A: Yes. Both parts feature identical mounting type (through hole, right angle), shrouding configuration (4 wall), contact geometry (square shape), and dimensional specifications including contact lengths, insulation height, and pitch. They are mechanically interchangeable in all board-level applications.

Q: What is the difference between tin-lead and tin post finishes?

A: The 1-103673-3 features tin-lead post finish while the 6-103673-3 features tin post finish. Both finishes provide equivalent solder joint reliability and electrical performance. The tin finish in the 6-103673-3 aligns with ROHS3 compliance requirements that restrict lead content in electronic components.

Q: Can I use the 6-103673-3 as a direct replacement for the 1-103673-3 in existing designs?

A: Yes. The 6-103673-3 is a direct substitute with identical electrical and mechanical specifications. The primary consideration is regulatory compliance: if your application or market requires ROHS3 certification, the 6-103673-3 is the appropriate selection.

Q: What applications are these connectors suitable for?

A: Both parts are rated for automotive, general purpose, medical, and telecommunications applications. The operating temperature range of -65°C to 105°C and 3A current rating support these diverse application categories.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in tube packaging. Inventory quantities differ: 1-103673-3 has 795 pieces in stock, while 6-103673-3 has 1,823 pieces available.

Q: What does the shrouded 4-wall configuration provide?

A: The shrouded 4-wall design provides mechanical protection and alignment guidance during mating operations. Combined with the board lock and keying slot features, this configuration ensures proper connector orientation and secure board-level mounting.

Q: Are these parts suitable for high-reliability applications?

A: Yes. Both parts carry UL94 V-0 flammability rating and feature gold-plated mating contacts (15.0µin thickness) for reliable electrical connection. The latch holder fastening mechanism and keying features support high-reliability assembly and operation.
