Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMS-150-01-S-D is determined by alignment across the following critical parameters:

Mandatory 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

Allowable Variation Parameters:

• Operating Temperature Range: Substitute must support the application's required temperature window
• Current Rating: Substitute must meet or exceed the circuit's current requirements
• Insulation Material: Thermoplastic alternatives acceptable if mechanical and electrical properties are maintained
• Contact Finish Thickness: Variations within industry standards acceptable

The substitute part 5-104078-8 (TE Connectivity AMP Connectors) satisfies all mandatory matching parameters and maintains functional equivalence for board-to-board interconnection applications.

Parameter Comparison

Engineering Selection Recommendations

SMS-150-01-S-D (Samtec Inc.) - Primary Selection

Select the SMS-150-01-S-D when the application requires:

• Current capacity of 5A per contact
• Operating temperature range extending to -55°C or above 105°C
• Liquid Crystal Polymer insulation material for specific mechanical or environmental requirements
• Active production status with established supply chain

5-104078-8 (TE Connectivity AMP Connectors) - Substitute Selection

The 5-104078-8 is functionally equivalent for board-to-board interconnection when:

• Circuit current requirements do not exceed 1A per contact
• Operating temperature range remains within -65°C to 105°C
• Thermoplastic glass-filled insulation material is acceptable
• Higher inventory availability (1558 pcs vs. 733 pcs) supports procurement timelines
• ROHS3 compliance and EAR99 classification match regulatory requirements

Critical Substitution Constraints:

The 5-104078-8 exhibits reduced current rating (1A vs. 5A per contact). Applications requiring the full 5A per contact capacity of the SMS-150-01-S-D cannot use this substitute without circuit redesign or parallel contact configuration. The operating temperature range of the substitute does not extend to -55°C; applications requiring operation below -65°C must use the SMS-150-01-S-D.

Both connectors are ROHS3 compliant and carry EAR99 classification, supporting equivalent regulatory and export compliance profiles.

Frequently Asked Questions (FAQ)

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

A: Direct replacement is possible only when circuit current requirements do not exceed 1A per contact and operating temperature remains within -65°C to 105°C. The SMS-150-01-S-D supports 5A per contact and extends to -55°C minimum temperature. Verify application current and temperature specifications before substitution.

Q: What is the difference in insulation material between these connectors?

A: The SMS-150-01-S-D uses Liquid Crystal Polymer (LCP) insulation, while the 5-104078-8 uses thermoplastic glass-filled material. Both materials provide adequate mechanical and electrical properties for board-to-board applications. LCP offers superior dimensional stability and lower moisture absorption; glass-filled thermoplastic provides cost efficiency. Material selection depends on application environmental exposure and mechanical stress requirements.

Q: Are the physical dimensions compatible for PCB layout?

A: Both connectors share identical pitch (0.050"), row spacing (0.100"), and contact post length (0.100"). Insulation height differs slightly: SMS-150-01-S-D measures 0.335" (8.51mm) while 5-104078-8 measures 0.350" (8.89mm). This 0.015" (0.38mm) variation is within typical PCB design tolerances and does not prevent mechanical substitution on standard board layouts.

Q: What compliance certifications apply to both parts?

A: Both SMS-150-01-S-D and 5-104078-8 are ROHS3 compliant and classified as EAR99 for export control purposes. The 5-104078-8 carries UL94 V-0 flammability rating and Moisture Sensitivity Level 1 (unlimited). Regulatory and compliance profiles are equivalent for standard commercial and industrial applications.

Q: How does current rating affect substitution decisions?

A: Current rating is a critical substitution parameter. The SMS-150-01-S-D supports 5A per contact; the 5-104078-8 supports 1A per contact. Applications designed for 5A per contact cannot use the substitute without exceeding contact current density limits, risking thermal stress and premature failure. Verify circuit current distribution across all 100 positions before selecting the substitute.

Q: What inventory considerations apply to these parts?

A: The SMS-150-01-S-D has 733 pcs in stock; the 5-104078-8 has 1558 pcs available. The substitute offers higher inventory availability, supporting faster procurement for non-critical applications. Both parts are actively produced and available in tube packaging.
