Key Parameters

Substitute Part Grouping Explanation

Substitution for the 77311-118-05 is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (5)
• Pitch - mating (0.100" / 2.54mm)
• Number of rows (1)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact shape (Square)
• Material flammability rating (UL94 V-0)
• Insulation color (Black)

The substitute parts listed below maintain these core electrical and mechanical parameters, ensuring functional compatibility in board-to-board connector applications. Variations in contact finish specifications, post termination details, and product status are noted but do not preclude substitution where the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

77311-118-05LF (Amphenol ICC) is the direct successor to the obsolete 77311-118-05. This part maintains identical mechanical and electrical specifications while offering active product status and RoHS compliance. The primary difference is the post finish change from tin-lead to tin, which aligns with modern manufacturing standards. This is the preferred substitute for direct replacement applications.

0423751247 (Molex KK254 Series) and 0423751351 (Molex KK254 Series) are manufacturer-recommended alternatives from Molex. Both parts maintain the critical 5-position, 0.100" pitch, through-hole header configuration with push-pull fastening. The Molex KK254 series offers active product status and ROHS3 compliance. The 0423751247 variant features standard solder termination, while 0423751351 includes kinked pin termination for enhanced mechanical retention. Contact finish differs from the original (tin versus gold), which may affect mating force characteristics in applications with specific contact resistance requirements.

TS-105-T-AA (Samtec Inc.) is an alternative header connector from the Samtec TS series. This part maintains the 5-position, 0.100" pitch configuration with through-hole solder termination and active product status with ROHS3 compliance. Samtec packaging is supplied in tube format. Limited parameter data is provided for this part; verification of fastening type and contact geometry is recommended for critical applications.

Selection should prioritize 77311-118-05LF for direct replacement due to specification alignment and Amphenol ICC continuity. Molex alternatives are suitable where supply or cost considerations warrant cross-manufacturer substitution. Samtec TS-105-T-AA may be considered where Samtec supply chain integration is preferred.

Frequently Asked Questions (FAQ)

Q: Can the 77311-118-05LF directly replace the obsolete 77311-118-05?

A: Yes. The 77311-118-05LF maintains identical connector type, contact configuration, pitch, mounting method, and termination. The primary change is post finish (tin versus tin-lead) and RoHS compliance status. This part is the direct successor and is recommended for replacement.

Q: What are the key differences between Amphenol ICC and Molex alternatives?

A: The Amphenol ICC 77311-118-05LF is a direct series continuation. Molex KK254 series parts (0423751247, 0423751351) are cross-manufacturer alternatives that maintain the same pitch, position count, and mounting type but use different insulation materials (polyamide/nylon glass-filled versus thermoplastic) and contact finishes (tin versus gold). Both Molex variants are active products with ROHS3 compliance.

Q: Are there compatibility concerns when substituting between manufacturers?

A: All listed substitutes maintain the 0.100" (2.54mm) pitch and 5-position configuration, ensuring mechanical compatibility with mating connectors designed for this standard. Contact finish differences (gold versus tin) may affect mating force and contact resistance; applications with specific electrical performance requirements should verify compatibility with the mating connector specification.

Q: What is the difference between 0423751247 and 0423751351?

A: Both are Molex KK254 series 5-position headers at 0.100" pitch. The primary difference is termination: 0423751247 uses standard solder termination, while 0423751351 uses kinked pin solder termination for enhanced mechanical retention on the PCB. Contact length specifications also differ slightly (0.240" versus 0.230" mating contact length).

Q: Does the change from tin-lead to tin post finish affect performance?

A: Tin-lead and tin post finishes both provide adequate solder joint formation and mechanical retention. The change reflects compliance with modern RoHS standards. No functional performance degradation is expected in standard through-hole solder applications.

Q: What packaging formats are available?

A: 77311-118-05LF is supplied in bulk packaging. TS-105-T-AA is supplied in tube packaging. Molex alternatives are supplied in bulk packaging. Packaging format should be verified against procurement and assembly requirements.

Q: Is the Samtec TS-105-T-AA suitable for all applications?

A: The TS-105-T-AA maintains the 5-position, 0.100" pitch, through-hole solder configuration. Limited parameter documentation is provided for this part. Verification of fastening type, contact geometry, and mating force characteristics is recommended before selection for applications with specific mechanical or electrical requirements.
