Key Parameters

Substitute Part Grouping Explanation

Substitution for the 77311-103-13 is determined by strict equivalence in the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Pitch: 13 positions at 0.100" (2.54mm) spacing
• Mounting & Termination: Through-hole solder termination
• Mechanical Compatibility: Board-to-board style with push-pull fastening
• Electrical & Environmental Ratings: UL94 V-0 flammability, MSL 1

The substitute parts identified maintain these core specifications while offering variations in product status, RoHS compliance, and contact finish specifications. The 77311-103-13LF is a direct manufacturer equivalent with improved compliance status. The 2313-6111-TG (3M) and TS-113-G-AA (Samtec) are functionally equivalent alternatives from different manufacturers meeting the same mechanical and electrical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 77311-103-13LF

The 77311-103-13LF is the direct manufacturer equivalent from Amphenol ICC. It maintains identical mechanical and electrical interface specifications while offering active product status and RoHS compliance. The primary difference is the post finish specification (Tin vs. Tin-Lead), which does not affect functional compatibility. This part is the preferred choice for direct replacement in active designs.

Alternative Recommendation: TS-113-G-AA (Samtec Inc.)

The TS-113-G-AA provides an equivalent 13-position header at 0.100" pitch with active product status and ROHS3 compliance. This option is suitable for designs requiring third-party sourcing or supply chain diversification. Mechanical and electrical interface compatibility is maintained.

Secondary Alternative: 2313-6111-TG (3M)

The 2313-6111-TG from 3M's 2300 series offers functional equivalence with active product status. This part features glass-filled thermoplastic insulation and maintains the required 13-position, 0.100" pitch configuration. Selection of this part should be based on specific supply chain or application requirements, as it does not offer RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the 77311-103-13LF be used as a direct replacement for the obsolete 77311-103-13?

A: Yes. The 77311-103-13LF maintains identical mechanical dimensions, pitch, position count, and board-to-board interface specifications. The primary difference is post finish (Tin vs. Tin-Lead) and improved RoHS compliance status. Functional compatibility is maintained.

Q: What are the key differences between the Amphenol and 3M alternatives?

A: Both maintain the 13-position, 0.100" pitch header configuration. The 3M 2313-6111-TG features glass-filled thermoplastic insulation and operates across a narrower temperature range (-55°C to 105°C vs. -65°C to 125°C for the Amphenol 77311-103-13LF). The Amphenol part offers RoHS compliance; the 3M part does not.

Q: Is the Samtec TS-113-G-AA mechanically compatible with the original 77311-103-13?

A: Yes. The TS-113-G-AA maintains the same 13-position, 0.100" pitch through-hole solder termination configuration. It is mechanically and electrically compatible for board-to-board applications.

Q: What is the significance of the contact finish differences?

A: The mating contact finish (gold) is identical across all parts. The post finish varies (Tin-Lead vs. Tin). Both finishes are suitable for solder termination and do not affect functional compatibility. The Tin finish in the 77311-103-13LF supports RoHS compliance.

Q: Are all substitute parts rated for the same current and voltage?

A: The 77311-103-13LF and 2313-6111-TG are both rated at 3A per contact. The original 77311-103-13 and TS-113-G-AA do not specify current ratings in the provided data. Voltage ratings are not specified for any part in this group.

Q: What packaging options are available?

A: The 77311-103-13LF is supplied in Bulk packaging. The TS-113-G-AA is supplied in Tube packaging. The original 77311-103-13 and 2313-6111-TG do not specify packaging in the provided data.
