2SH-C-04-TR-SMT Equivalent & Substitute Parts

Part Overview

The 2SH-C-04-TR-SMT is a rectangular connector header manufactured by Adam Tech, designed for surface mount, right-angle applications with 4 positions at 2.00mm pitch. This component is classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity. The shrouded 4-wall design with solder termination serves board-to-cable/wire interconnection requirements in applications requiring 2A current capacity at 100VAC.

Key Parameters

Substitute Part Grouping Explanation

The DF3E-4P-2H(54) manufactured by Hirose Electric Co Ltd qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 4
• Number of Rows: 1
• Mounting Type: Surface Mount, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

Substitution is valid where the electrical and mechanical interface requirements align with these core parameters. The DF3E-4P-2H(54) maintains dimensional and functional compatibility for applications requiring 4-position, 2.00mm pitch surface mount headers with shrouded construction.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-4P-2H(54) is suitable as a direct substitute for the obsolete 2SH-C-04-TR-SMT in applications where the following conditions are met:

Compliance & Status Considerations:

• Both components meet UL94 V-0 flammability requirements
• Both components carry MSL 1 (Unlimited) moisture sensitivity classification
• The DF3E-4P-2H(54) maintains RoHS compliance, supporting regulatory continuity

Electrical Performance:

• The DF3E-4P-2H(54) exceeds the voltage rating requirement (250VAC vs. 100VAC), providing margin for applications within the original 100VAC specification
• Current rating specifications differ in definition; the DF3E-4P-2H(54) current capacity is wire gauge dependent, requiring verification against specific application wire gauges

Mechanical & Environmental:

• The DF3E-4P-2H(54) supports an extended operating temperature range (-55°C ~ 105°C vs. -25°C ~ 85°C), accommodating broader environmental conditions
• Insulation material differs (Polyamide/Nylon vs. Thermoplastic); both materials maintain equivalent flammability ratings

Packaging & Availability:

• The DF3E-4P-2H(54) is classified as Last Time Buy; procurement planning should account for limited future availability
• Packaging format is Tube, differing from the original specification

Frequently Asked Questions (FAQ)

Q: Can the DF3E-4P-2H(54) directly replace the 2SH-C-04-TR-SMT in existing designs?

A: Yes, for applications operating within 100VAC and -25°C to 85°C, the DF3E-4P-2H(54) provides functional equivalence. The matching pitch (2.00mm), position count (4), mounting type (surface mount right-angle), and shrouding (4-wall) ensure mechanical and electrical interface compatibility. Verify wire gauge compatibility with the DF3E-4P-2H(54) current rating specification.

Q: What are the key differences between these two connectors?

A: Primary differences include contact finish (Tin vs. Gold), insulation material (Thermoplastic vs. Polyamide/Nylon), operating temperature range (extended on the DF3E-4P-2H(54)), voltage rating (250VAC vs. 100VAC), and fastening type (none specified vs. Push-Pull on the DF3E-4P-2H(54)). Both maintain identical pitch, position count, mounting configuration, and flammability rating.

Q: Are there packaging considerations when switching to the DF3E-4P-2H(54)?

A: Yes. The DF3E-4P-2H(54) is supplied in Tube packaging, whereas the original part packaging is not specified. Tube packaging affects handling, storage, and automated assembly processes. Confirm compatibility with your procurement and assembly workflows.

Q: Does the gold contact finish on the DF3E-4P-2H(54) affect compatibility?

A: The gold contact finish on the DF3E-4P-2H(54) provides enhanced corrosion resistance compared to the tin finish on the 2SH-C-04-TR-SMT. This is functionally compatible and does not prevent substitution; gold finishes are generally considered superior for long-term reliability in mating cycles.

Q: What is the significance of the Last Time Buy status for the DF3E-4P-2H(54)?

A: Last Time Buy status indicates limited future manufacturing availability. Current inventory is 910 pieces. For long-term production requirements, establish procurement timelines and consider alternative sources or design modifications to ensure supply continuity beyond the Last Time Buy window.
