TE Connectivity 104078-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 104078-7 is an 80-position receptacle connector from the AMPMODU System 50 series, designed for board-to-board applications. This connector features 0.050" (1.27mm) pitch mating contacts with gold plating, through-hole solder termination, and push-pull fastening. The part is classified as Active product status and is suitable for applications requiring reliable interconnection in temperature ranges from -65°C to 105°C. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory availability, compliance requirements, or design flexibility within established parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors within the AMPMODU System 50 series is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Contact pitch (0.050" / 1.27mm mating pitch)
• Number of positions (80 positions)
• Row configuration (2 rows with 0.100" / 2.54mm spacing)
• Current rating (1A per contact)
• Voltage rating (30VAC)
• Contact finish type (gold mating surface)

Mechanical Compatibility Parameters:

• Connector type (receptacle)
• Contact type (female socket)
• Mounting method (through-hole solder termination)
• Fastening mechanism (push-pull)
• Insulation material (thermoplastic, glass-filled)
• Operating temperature range (-65°C to 105°C)
• Flammability rating (UL94 V-0)

Compliance Parameters:

• Series designation (AMPMODU System 50)
• Base product number (104078)

The substitute part 5-104078-7 maintains full equivalence across all electrical and mechanical parameters. Variations in post-contact finish material (tin versus tin-lead) and RoHS compliance status do not affect functional interchangeability within the specified electrical and thermal operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (104078-7): The TE Connectivity 104078-7 is the baseline specification for this connector family. This part carries Active product status and is suitable for applications where tin-lead post plating is acceptable. Current inventory of 724 pieces supports immediate deployment. The part is classified as REACH Affected, indicating full regulatory documentation is available from the manufacturer.

Substitute Part Selection (5-104078-7): The 5-104078-7 variant is functionally equivalent across all electrical and mechanical parameters. This part offers ROHS3 compliance, making it suitable for applications with RoHS regulatory requirements. The higher inventory level (1464 pieces) provides extended availability. The post-contact finish is tin rather than tin-lead, which does not affect electrical performance within the specified operating parameters. REACH status is listed as Vendor Undefined, requiring clarification from the supplier for applications with strict REACH compliance mandates.

Selection Criteria:

• Use 104078-7 when tin-lead post plating is specified or preferred
• Use 5-104078-7 when RoHS3 compliance is required
• Both parts are interchangeable for electrical and mechanical function
• Inventory availability may influence selection between the two variants

Frequently Asked Questions (FAQ)

Q: Are the 104078-7 and 5-104078-7 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 80-position configuration, 0.050" (1.27mm) pitch, 2-row layout with 0.100" (2.54mm) row spacing, through-hole mounting, and push-pull fastening. Mated stacking heights are identical at 11.43mm and 12.57mm.

Q: What is the difference between the post-contact finishes (tin-lead versus tin)?

A: The 104078-7 features tin-lead post plating at 150.0µin (3.81µm) thickness, while the 5-104078-7 features tin post plating at the same thickness. Both finishes provide equivalent electrical conductivity and solder joint reliability within the specified operating parameters. The tin finish in the 5-104078-7 supports RoHS3 compliance.

Q: Can I use the 5-104078-7 as a direct replacement for the 104078-7 in existing designs?

A: Yes, the 5-104078-7 is a direct functional substitute. All electrical parameters (1A current rating, 30VAC voltage rating), mechanical dimensions, and thermal operating range (-65°C to 105°C) are identical. The primary difference is RoHS3 compliance status and post-contact finish material.

Q: What is the significance of the ROHS3 compliance on the 5-104078-7?

A: ROHS3 compliance indicates the 5-104078-7 meets Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials. This is relevant for applications subject to European Union regulations or customer specifications requiring RoHS compliance. The 104078-7 is listed as "Not applicable" for RoHS status.

Q: Are both parts suitable for the same temperature range?

A: Yes. Both the 104078-7 and 5-104078-7 operate across the identical temperature range of -65°C to 105°C and carry the same UL94 V-0 flammability rating.

Q: What does "Moisture Sensitivity Level 1 (Unlimited)" mean?

A: MSL 1 indicates the connector has unlimited shelf life and does not require special moisture-controlled storage conditions. Both parts carry this classification, meaning standard warehouse storage is acceptable without desiccant packaging or humidity controls.

Q: How do the inventory levels affect part selection?

A: The 5-104078-7 has higher current inventory (1464 pieces) compared to the 104078-7 (724 pieces). For applications requiring immediate large-quantity procurement, the 5-104078-7 may offer better availability. For smaller quantities, both parts are in stock.

Q: Are there any electrical performance differences between these two connectors?

A: No. Both connectors maintain identical electrical specifications: 1A current rating per contact, 30VAC voltage rating, gold mating contact finish at 30.0µin (0.76µm) thickness, and copper alloy contact material. Electrical performance is equivalent across all operating conditions within the specified envelope.
