Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMS-150-01-G-D is determined by strict alignment of the following core parameters:

Critical Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 100
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Style: Board to Board

The substitute part 5-104078-8 (TE Connectivity AMP Connectors) satisfies all critical matching parameters, establishing functional equivalence for direct replacement applications. Both connectors maintain identical mating interface geometry, contact arrangement, and board-level integration requirements.

Parameter Comparison

Engineering Selection Recommendations

Both SMS-150-01-G-D and 5-104078-8 maintain Active product status and ROHS3 compliance, confirming current manufacturing availability and regulatory alignment.

Parameter Variations Requiring Application Assessment:

The substitute part 5-104078-8 exhibits three parameter variations from the primary specification:

1. Current Rating: SMS-150-01-G-D is rated 5A per contact; 5-104078-8 is rated 1A per contact. Applications requiring current levels exceeding 1A per contact cannot use the substitute without circuit redesign.

2. Operating Temperature Range: SMS-150-01-G-D operates -55°C to 125°C; 5-104078-8 operates -65°C to 105°C. Applications requiring sustained operation above 105°C cannot use the substitute.

3. Contact Finish Thickness - Mating: SMS-150-01-G-D specifies 10.0µin (0.25µm); 5-104078-8 specifies 30.0µin (0.76µm). The substitute provides increased gold plating thickness, which does not degrade performance in standard applications.

4. Insulation Height: SMS-150-01-G-D measures 0.335" (8.51mm); 5-104078-8 measures 0.350" (8.89mm). This 0.015" (0.38mm) difference requires PCB layout verification to confirm clearance compatibility.

Selection of the substitute part is appropriate only when application requirements remain within the substitute's electrical and thermal specifications.

Frequently Asked Questions (FAQ)

Q: Can 5-104078-8 directly replace SMS-150-01-G-D in all applications?

A: Direct replacement is possible only when the application current requirement does not exceed 1A per contact and operating temperature remains within -65°C to 105°C. The mating interface geometry and board-level integration are identical, enabling mechanical and electrical compatibility within these parameter boundaries.

Q: What is the significance of the current rating difference?

A: The SMS-150-01-G-D supports 5A per contact, while 5-104078-8 supports 1A per contact. This represents a fundamental difference in contact design and current-carrying capacity. Applications designed for 5A operation cannot use the 1A-rated substitute without circuit modification or parallel contact implementation.

Q: Does the increased gold plating thickness on 5-104078-8 affect compatibility?

A: No. The increased contact finish thickness (30.0µin versus 10.0µin) on the substitute part provides enhanced durability and corrosion resistance. This variation does not compromise mating interface performance or electrical characteristics in standard applications.

Q: Are there PCB layout considerations when substituting these parts?

A: Yes. The insulation height difference of 0.015" (0.38mm) between the two connectors requires verification of PCB clearance and component placement. Confirm that the substitute's 0.350" (8.89mm) height does not conflict with adjacent board-level components or assembly constraints.

Q: Do both parts support the same mating connector?

A: Yes. Both receptacle connectors feature identical mating interface specifications: 0.050" (1.27mm) pitch, 100 positions, 2 rows, and 0.100" (2.54mm) row spacing. Mating plugs designed for SMS-150-01-G-D are mechanically and electrically compatible with 5-104078-8.

Q: What is the temperature operating range difference impact?

A: SMS-150-01-G-D operates to 125°C maximum; 5-104078-8 operates to 105°C maximum. Applications requiring sustained operation above 105°C must use the primary part. The substitute's lower temperature ceiling reflects different insulation material properties (Thermoplastic, Glass Filled versus Liquid Crystal Polymer).
