Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity Erni 354094-E is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 16
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Operating Temperature Range: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The Adam Tech ESMC-M-16-SGR-SMT-T/R meets all mandatory matching parameters and qualifies as a direct substitute. Variations in packaging format (Tape & Reel versus Cut Tape), contact material composition, insulation material type, and fastening mechanism do not preclude substitution when all critical electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity Erni 354094-E and Adam Tech ESMC-M-16-SGR-SMT-T/R are active production components with ROHS3 compliance and UL94 V-0 flammability certification. Both parts maintain identical operating temperature ranges (-55°C ~ 125°C) and moisture sensitivity levels (MSL 1 - Unlimited), ensuring compatibility in equivalent thermal and environmental conditions.

The primary distinction between these parts is the current rating per contact: the TE Connectivity part is rated at 1.7A per contact, while the Adam Tech substitute is rated at 1.2A per contact. Circuit designs operating at or below 1.2A per contact can utilize either part interchangeably. Designs requiring current levels between 1.2A and 1.7A per contact must use the TE Connectivity Erni 354094-E.

Secondary differences include contact material (Copper Alloy versus Phosphor Bronze) and insulation material (Liquid Crystal Polymer versus Thermoplastic). These material variations do not affect substitution eligibility when electrical and mechanical parameters align. Packaging format differences (Tape & Reel versus Cut Tape) reflect procurement and assembly process considerations rather than functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Adam Tech ESMC-M-16-SGR-SMT-T/R be used as a direct replacement for the TE Connectivity Erni 354094-E in all applications?

A: The Adam Tech part qualifies as a substitute when circuit current requirements do not exceed 1.2A per contact. The TE Connectivity part supports 1.7A per contact. If your design operates within the 1.2A limit, both parts are functionally equivalent. If your design requires current levels between 1.2A and 1.7A per contact, the TE Connectivity part is required.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by matching: 16-position configuration, 2-row layout, 0.050" (1.27mm) pitch spacing, right-angle surface mount orientation, shrouded 4-wall construction, solder termination, -55°C to 125°C operating range, UL94 V-0 flammability rating, and ROHS3 compliance. All these parameters are identical between the main part and substitute.

Q: Does the difference in packaging format (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format differences reflect supply chain and assembly process considerations only. Tape & Reel (TR) packaging is optimized for high-volume automated assembly, while Cut Tape (CT) packaging is suitable for lower-volume or mixed-component applications. Electrical and mechanical performance is identical.

Q: Are there differences in contact material between these parts?

A: Yes. The TE Connectivity part uses Copper Alloy contacts, while the Adam Tech part uses Phosphor Bronze contacts. Both materials are standard for connector applications and provide equivalent performance in this connector class. The gold mating finish on both parts ensures consistent contact resistance and reliability.

Q: What is the significance of the insulation material difference (LCP versus Thermoplastic)?

A: Both Liquid Crystal Polymer (LCP) and Thermoplastic materials meet UL94 V-0 flammability requirements and are suitable for this connector application. LCP offers superior dimensional stability and higher temperature performance characteristics, while Thermoplastic provides cost efficiency. Both materials maintain the specified operating temperature range of -55°C to 125°C.

Q: Can these parts be intermixed in the same assembly?

A: Yes. Both parts are mechanically and electrically compatible when substituted within the same design. However, current rating limitations apply: if any single contact in your design carries current between 1.2A and 1.7A, all connectors in that circuit must use the TE Connectivity part to ensure uniform current handling capability.

Q: What inventory considerations should guide part selection?

A: The TE Connectivity Erni 354094-E has 1297 pieces in stock (Tape & Reel packaging), while the Adam Tech ESMC-M-16-SGR-SMT-T/R has 1595 pieces in stock (Cut Tape packaging). Inventory availability and packaging format should be evaluated against assembly process requirements and current rating specifications.
