Substitute Part Grouping Explanation

The substitute part 6-104078-3 (TE Connectivity AMP Connectors) is identified as functionally equivalent based on the following critical parameters:

• Connector Configuration: Both parts are 68-position receptacle connectors with identical 0.050" (1.27mm) mating pitch
• Physical Layout: Both feature 2-row configuration with 0.100" (2.54mm) row spacing
• Termination Method: Both use through-hole solder termination with push-pull fastening
• Contact Interface: Both provide gold-plated mating contacts at 30.0µin (0.76µm) thickness
• Board-to-Board Application: Both are designed for identical mounting and interconnection topology

Substitution is valid where these core parameters align, enabling direct replacement in applications requiring 68-position 0.050" pitch board-to-board connectivity.

Parameter Comparison

Engineering Selection Recommendations

Both SMS-134-01-S-D and 6-104078-3 are active production parts with RoHS compliance and MSL 1 rating, suitable for applications without moisture sensitivity constraints. The SMS-134-01-S-D carries ROHS3 compliance, while 6-104078-3 meets RoHS requirements. Selection between these parts should be based on availability, supply chain requirements, and design qualification status. The 0.015" (0.38mm) difference in insulation height (SMS-134-01-S-D at 0.335" versus 6-104078-3 at 0.350") must be evaluated for mechanical clearance in the target application. Both parts maintain identical electrical mating characteristics and contact post specifications, ensuring functional interchangeability in standard board-to-board interconnect applications.

Frequently Asked Questions (FAQ)

Q: What makes 6-104078-3 a valid substitute for SMS-134-01-S-D?

A: Both connectors share identical core specifications: 68-position receptacle configuration, 0.050" (1.27mm) mating pitch, 2-row layout with 0.100" (2.54mm) row spacing, through-hole solder termination, push-pull fastening, and gold-plated mating contacts at 30.0µin thickness. These parameters define the mating interface and electrical performance, making them functionally equivalent for board-to-board applications.

Q: Are there any physical differences between these parts?

A: The insulation height differs slightly: SMS-134-01-S-D measures 0.335" (8.51mm) while 6-104078-3 measures 0.350" (8.89mm). This 0.015" (0.38mm) variation must be considered for mechanical clearance verification in confined spaces or when stacking multiple connectors.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. SMS-134-01-S-D is ROHS3 compliant, while 6-104078-3 meets RoHS requirements. Both are suitable for standard industrial and commercial applications without additional moisture protection measures.

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

A: Yes, provided the mechanical envelope accommodates the insulation height difference and the design has not been specifically qualified to a single manufacturer's part. The identical mating pitch, contact configuration, and termination method ensure electrical and mechanical compatibility.

Q: What should be verified before substituting one part for the other?

A: Verify mechanical clearance around the connector body, confirm PCB layout compatibility with the insulation height specification, and ensure the design does not contain manufacturer-specific requirements or qualifications that would restrict substitution.
