TE Connectivity AMP Connectors 9-103801-0 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 9-103801-0 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features 80 positions across 2 rows with 0.100" (2.54mm) pitch spacing, suitable for board-to-board or cable interconnection. The part is classified as Active product status with full position loading and unshrouded design. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of critical electrical and mechanical parameters. The following parameters establish substitution validity:

Critical Matching Parameters:

• Number of Positions: 80
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Contact Type: Male Pin
• Termination: Solder
• Current Rating: 3A
• Material Flammability Rating: UL94 V-0

The 3M 2380-5121TG meets all critical matching parameters, establishing it as a valid substitute for the TE Connectivity 9-103801-0. Both parts share identical position configuration, pitch spacing, mounting orientation, contact type, and current handling capacity. Variations in secondary parameters such as contact finish thickness, insulation material composition, and operating temperature range do not preclude substitution when primary electrical and mechanical requirements align.

Engineering Selection Recommendations

TE Connectivity 9-103801-0 (Primary Part)

The TE Connectivity 9-103801-0 is the original specification component with Active product status. This part carries ROHS3 compliance certification, meeting current regulatory requirements for restricted substances. The operating temperature range extends to -65°C, providing broader environmental tolerance for applications requiring extended low-temperature operation. The contact finish thickness on mating surfaces is specified at 30.0µin (0.76µm), supporting extended service life in high-cycle mating applications.

3M 2380-5121TG (Substitute Part)

The 3M 2380-5121TG is a valid electrical and mechanical substitute with Active product status. This part is classified as RoHS non-compliant, which restricts its use in applications subject to RoHS3 regulatory requirements. The operating temperature range is limited to -55°C minimum, excluding applications requiring operation below this threshold. The contact finish on posts is specified as Tin-Lead, which may present compatibility considerations in lead-free assembly environments. The insulation material includes glass-filled thermoplastic, providing enhanced mechanical properties compared to unfilled thermoplastic.

Selection between these parts depends on regulatory compliance requirements, operating temperature specifications, and assembly process constraints. The TE Connectivity part is appropriate for RoHS3-regulated applications and extended low-temperature environments. The 3M part is suitable for applications where RoHS compliance is not mandated and operating temperatures remain above -55°C.

Frequently Asked Questions (FAQ)

Q: What determines whether the 3M 2380-5121TG can substitute for the TE Connectivity 9-103801-0?

A: Substitution is valid when critical electrical and mechanical parameters match: 80 positions, 2 rows, 0.100" (2.54mm) pitch, through-hole right-angle mounting, male pin contacts, solder termination, 3A current rating, and UL94 V-0 flammability rating. The 3M part meets all these criteria.

Q: Are there differences in contact post length between these parts?

A: Yes. The TE Connectivity 9-103801-0 specifies 0.090" (2.29mm) contact post length, while the 3M 2380-5121TG specifies 0.110" (2.79mm). This difference may affect PCB hole depth requirements and should be verified during design integration.

Q: What is the significance of the RoHS compliance difference?

A: The TE Connectivity part is ROHS3 compliant, meeting current regulatory requirements for restricted substances in electrical and electronic equipment. The 3M part is RoHS non-compliant and cannot be used in applications subject to RoHS3 regulations. Compliance requirements depend on end-use application and geographic market.

Q: How do the operating temperature ranges differ?

A: The TE Connectivity 9-103801-0 operates from -65°C to 105°C, while the 3M 2380-5121TG operates from -55°C to 105°C. Applications requiring operation below -55°C must use the TE Connectivity part.

Q: What is the difference in contact finish on the mating surfaces?

A: Both parts specify gold contact finish on mating surfaces. However, the TE Connectivity part specifies 30.0µin (0.76µm) thickness, while the 3M part specifies 10.0µin (0.25µm). Thicker gold plating generally provides longer service life in high-cycle mating applications.

Q: Does the glass-filled insulation material in the 3M part affect compatibility?

A: The 3M part uses glass-filled thermoplastic insulation, while the TE Connectivity part uses unfilled thermoplastic. Glass-filled material provides enhanced mechanical strength and dimensional stability. This difference does not affect electrical compatibility but may influence mechanical performance in applications subject to vibration or thermal cycling.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability depends on design-specific requirements. Both parts share identical pitch, position count, and mounting configuration. However, differences in contact post length, operating temperature range, and RoHS compliance must be evaluated against specific application requirements before substitution.

Q: What inventory considerations apply to these parts?

A: The TE Connectivity 9-103801-0 has 973 pieces in stock, while the 3M 2380-5121TG has 1436 pieces in stock. Availability may influence sourcing decisions when immediate delivery is required.
