TE Connectivity 1-103166-3 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-103166-3 is a shrouded rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole, right-angle header accommodates 30 positions across 2 rows with 0.100" (2.54mm) pitch spacing and is designed for board-to-board or cable interconnection applications. The connector features gold-plated mating contacts and tin-lead plated posts for solder termination.

The 1-103166-3 maintains active product status with 945 units currently in stock. Identification of equivalent substitute parts becomes necessary when primary inventory is depleted, when design revisions require updated compliance certifications, or when procurement from alternative sources is required.

• Mounting configuration: Through hole, right angle
• Shrouding type: Shrouded - 4 wall
• Contact type: Male pin
• Contact length (mating): 0.318" (8.08mm)
• Contact length (post): 0.135" (3.43mm)
• Insulation height: 0.400" (10.16mm)
• Current rating: 3A
• Operating temperature range: -65°C ~ 105°C
• Contact material: Phosphor bronze
• Insulation material: Thermoplastic
• Flammability rating: UL94 V-0
• Termination: Solder
• Fastening: Detent lock

The substitute part 6-103166-3 meets all mechanical and electrical parameters required for direct substitution with the primary part 1-103166-3.

Parameter Comparison

Engineering Selection Recommendations

The 6-103166-3 qualifies as a direct electrical and mechanical substitute for the 1-103166-3 based on complete parameter equivalence across all critical connector specifications. Both parts share identical pitch spacing, contact geometry, current rating, temperature range, and mechanical mounting characteristics.

Compliance Considerations:

The 6-103166-3 carries ROHS3 compliance certification and REACH Unaffected status, providing enhanced regulatory documentation compared to the 1-103166-3, which lists RoHS status as not applicable and REACH status as vendor undefined. For applications requiring documented compliance with current environmental regulations, the 6-103166-3 offers superior certification standing.

Contact Finish Variation:

The 6-103166-3 features tin-plated posts, whereas the 1-103166-3 specifies tin-lead plating. Both finishes maintain identical thickness specifications (100.0µin / 2.54µm) and are compatible with standard solder termination processes. This variation does not affect electrical or mechanical performance.

Product Status:

The 1-103166-3 maintains active product status with current inventory availability. The 6-103166-3 is discontinued at DiGi Electronics but remains available through alternative distribution channels. Selection between these parts should prioritize the 1-103166-3 for new designs requiring long-term supply assurance, while the 6-103166-3 serves as a viable substitute when primary inventory is unavailable.

Frequently Asked Questions (FAQ)

Q: Can the 6-103166-3 be used as a direct replacement for the 1-103166-3 in existing designs?

A: Yes. The 6-103166-3 meets all mechanical and electrical specifications required for direct substitution. Both parts feature identical pitch spacing (0.100" / 2.54mm), contact geometry, current rating (3A), operating temperature range (-65°C ~ 105°C), and mounting configuration (through-hole, right-angle, shrouded 4-wall).

Q: What is the difference between the tin-lead finish on the 1-103166-3 and the tin finish on the 6-103166-3?

A: Both finishes are applied at identical thickness (100.0µin / 2.54µm) to the connector posts. The tin finish on the 6-103166-3 represents a lead-free alternative to the tin-lead finish on the 1-103166-3. Both are compatible with standard solder termination processes and do not affect electrical performance or mechanical compatibility.

Q: Why does the 6-103166-3 show discontinued status while the 1-103166-3 is active?

A: The 6-103166-3 is discontinued at DiGi Electronics specifically, but may remain available through other authorized TE Connectivity distributors. The 1-103166-3 maintains active status with current production and inventory support. For new designs, the 1-103166-3 is the preferred selection for supply continuity.

Q: Are there any compliance differences between these two parts?

A: The 6-103166-3 carries ROHS3 compliance certification and REACH Unaffected status. The 1-103166-3 lists RoHS status as not applicable and REACH status as vendor undefined. Both parts meet UL94 V-0 flammability requirements. For applications requiring documented environmental compliance, the 6-103166-3 provides explicit certification.

Q: Do both parts use the same packaging?

A: The 1-103166-3 is packaged in trays. Packaging information for the 6-103166-3 is not specified in available documentation. Confirm packaging requirements with your distributor when sourcing the 6-103166-3.

Q: What is the row spacing on these connectors?

A: Both the 1-103166-3 and 6-103166-3 feature 0.100" (2.54mm) row spacing at mating, identical to the pitch spacing. This configuration accommodates standard 0.100" spaced receptacle connectors and mating headers.

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

A: Yes. Both parts are classified as board-to-board or cable style connectors. The through-hole, right-angle mounting configuration and detent lock fastening support both application types.
