• Number of Positions: 30 — exact match required
• Number of Rows: 2 — exact match required
• Row Spacing - Mating: 0.100" (2.54mm) — exact match required
• Connector Type: Header — exact match required
• Contact Type: Male Pin — exact match required
• Mounting Type: Through Hole — exact match required
• Termination: Solder — exact match required
• Style: Board to Board or Board to Board/Cable — compatible
• Shrouding: Unshrouded — exact match required
• Number of Positions Loaded: All — exact match required
• Fastening Type: Push-Pull — exact match required
• Contact Shape: Square — exact match required
• Insulation Height: 0.100" (2.54mm) — exact match required
• Product Status: Active — required for current production use
• RoHS Status: ROHS3 Compliant — required for regulatory compliance

The substitute part 5-103916-9 (TE Connectivity AMP Connectors) meets all critical mechanical and electrical parameters for direct substitution in applications where the TMS-115-02-G-D is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the TMS-115-02-G-D and 5-103916-9 are active production parts with ROHS3 compliance and UL94 V-0 flammability ratings, meeting current regulatory requirements. The parts are mechanically and electrically interchangeable for board-to-board through-hole solder applications with 30-position, 2-row configurations at 0.050" (1.27mm) pitch.

The TMS-115-02-G-D specifies a 5A per contact current rating with Phosphor Bronze contacts and Liquid Crystal Polymer insulation. The 5-103916-9 specifies 30VAC voltage rating with Copper Alloy contacts and Thermoplastic insulation. Both parts maintain identical pitch, position count, row spacing, and fastening characteristics required for direct substitution in board-to-board applications.

Selection between these parts should be based on availability, lead time, and application-specific requirements for contact material, insulation material, and rated electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5-103916-9 directly replace the TMS-115-02-G-D in existing designs?

A: Yes. Both parts share identical mechanical dimensions, pitch (0.050" / 1.27mm), position count (30), row configuration (2 rows), and mounting characteristics (through-hole solder). The parts are mechanically and electrically interchangeable for board-to-board applications.

Q: What are the differences in contact material between these parts?

A: The TMS-115-02-G-D uses Phosphor Bronze contacts, while the 5-103916-9 uses Copper Alloy contacts. Both are gold-plated at the mating surface. Contact material selection depends on application-specific requirements for spring force, durability, and electrical performance.

Q: Are there differences in operating temperature ranges?

A: The TMS-115-02-G-D operates from -55°C to 125°C, while the 5-103916-9 operates from -65°C to 105°C. The overlapping range (-55°C to 105°C) is suitable for most standard industrial and commercial applications. Applications requiring operation above 105°C or below -65°C require the TMS-115-02-G-D.

Q: What is the difference in insulation material?

A: The TMS-115-02-G-D uses Liquid Crystal Polymer (LCP) insulation, while the 5-103916-9 uses Thermoplastic insulation. Both materials meet UL94 V-0 flammability requirements. LCP provides superior dimensional stability and thermal performance, while Thermoplastic offers cost efficiency.

Q: Are both parts RoHS compliant?

A: Yes. Both the TMS-115-02-G-D and 5-103916-9 are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), meeting current regulatory requirements for electronic component manufacturing and assembly.

Q: What is the difference in current and voltage ratings?

A: The TMS-115-02-G-D specifies 5A per contact current rating. The 5-103916-9 specifies 30VAC voltage rating. Applications requiring specific current or voltage performance should reference the respective datasheet for the selected part.

Q: Can these parts be used interchangeably in automotive applications?

A: The 5-103916-9 is listed for automotive applications. Both parts meet UL94 V-0 flammability and ROHS3 compliance. Application-specific validation is required to confirm suitability for automotive environments, including thermal cycling, vibration, and humidity exposure requirements.
