TE Connectivity 103673-8 Rectangular Connector Header – Equivalent & Substitute Parts

Part Overview

The TE Connectivity 103673-8 is a rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This 9-position, single-row header operates within the AMPMODU MTE series and features shrouded 4-wall construction with solder termination. The connector is classified as Active product status and is suitable for automotive, general purpose, medical, and telecommunications applications. Identifying equivalent and substitute parts is necessary when managing inventory constraints, addressing supply chain variations, or accommodating specific compliance requirements across different manufacturing batches or procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across mechanical and electrical parameters. The primary substitution criteria for the TE Connectivity 103673-8 are:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (9)
• Number of rows (1)
• Pitch - mating (0.100" / 2.54mm)
• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact dimensions (Mating length 0.230", Post length 0.130")
• Insulation height (0.200")
• Contact shape (Square)
• Current rating (3A)
• Operating temperature range (-65°C ~ 105°C)
• Material flammability (UL94 V-0)
• Features (Board Lock, Keying Slot)

The substitute part 5-103673-8 maintains full equivalence across all mechanical and electrical parameters. Variations in contact finish post material (Tin-Lead versus Tin) and RoHS compliance status represent secondary differences that do not affect functional interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 103673-8 and its substitute 5-103673-8 are classified as Active product status and maintain full electrical and mechanical equivalence across all specified parameters. The primary distinction between these parts is the RoHS compliance status: the 103673-8 is marked as "Not applicable," while the 5-103673-8 is "RoHS Compliant."

For applications requiring RoHS compliance, the 5-103673-8 is the appropriate selection. For applications without RoHS requirements or where legacy compliance status is acceptable, either part is functionally equivalent. The contact finish post material difference (Tin-Lead in 103673-8 versus Tin in 5-103673-8) does not affect functional interchangeability within the specified electrical and mechanical parameter set.

Both parts are suitable for automotive, general purpose, medical, and telecommunications applications and operate within the identical temperature range of -65°C to 105°C with a 3A current rating and UL94 V-0 flammability classification.

Frequently Asked Questions (FAQ)

Q: Are the 103673-8 and 5-103673-8 fully interchangeable?

A: Yes. Both parts are mechanically and electrically equivalent across all specified parameters including connector type, position count, pitch, mounting configuration, termination method, contact dimensions, current rating, and operating temperature range. They are direct substitutes within the AMPMODU MTE series.

Q: What is the difference between the contact finish post materials?

A: The 103673-8 features Tin-Lead post finish, while the 5-103673-8 features Tin post finish. Both maintain the same contact finish thickness of 100.0µin (2.54µm). This difference does not affect functional performance within the specified electrical and mechanical parameters.

Q: Which part should be selected for RoHS-compliant applications?

A: The 5-103673-8 is designated as RoHS Compliant. The 103673-8 is marked as "Not applicable" for RoHS status. For applications requiring RoHS compliance certification, the 5-103673-8 is the appropriate selection.

Q: Are both parts suitable for automotive and medical applications?

A: Yes. Both the 103673-8 and 5-103673-8 are listed for automotive, general purpose, medical, and telecommunications applications. Both maintain UL94 V-0 material flammability rating and operate across the -65°C to 105°C temperature range required for these sectors.

Q: What is the packaging format for these connectors?

A: Both parts are supplied in Tube packaging. The 103673-8 has 802 pieces in stock, while the 5-103673-8 has 1935 pieces in stock.

Q: Can these headers be used for board-to-board and cable applications?

A: Yes. Both parts are classified as Board to Board or Cable style connectors with through-hole, right-angle mounting and solder termination, supporting both application types.

Q: What is the mating pitch specification?

A: Both parts feature a 0.100" (2.54mm) mating pitch, which is the standard spacing between contact positions in the 9-position header configuration.

Q: Are there any moisture sensitivity concerns?

A: No. Both parts are classified as Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
