Key Parameters

Substitute Part Grouping Explanation

Substitution for the 77311-122-13 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (13)
• Pitch - mating (0.100" / 2.54mm)
• Number of rows (1)
• Mounting type (Through Hole)
• Termination (Solder)
• Contact shape (Square)
• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (1 / Unlimited)

The substitute parts identified maintain these core electrical and mechanical specifications. Variations in contact finish, contact length, operating temperature range, and RoHS compliance status are noted but do not prevent functional substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

77311-122-13LF (Amphenol ICC) is the direct equivalent from the original manufacturer. This part maintains identical mechanical and electrical specifications to the 77311-122-13 while offering active product status and RoHS compliance. The LF designation indicates lead-free termination on the post contact, with tin finish replacing the original tin-lead. Operating temperature range extends to -65°C ~ 125°C with 3A per contact current rating.

2313-6211-TG (3M) provides an alternative from a major connector manufacturer. The 2300 series header maintains the required 13-position, 2.54mm pitch configuration with board-to-board or cable compatibility. Contact length specifications differ slightly (0.318" mating vs. 0.305" on the original), and the insulation material includes glass filling. Operating temperature is -55°C ~ 105°C with 3A current rating. RoHS compliant status applies.

2313-6211-TP (3M) offers the same mechanical and electrical specifications as the 2313-6211-TG with tin-lead mating contact finish instead of gold. RoHS non-compliant status matches the original part. This option is suitable for applications where lead-containing finishes are acceptable.

4-644456-3 (TE Connectivity AMP) is a MTA-100 series header with 13 positions at 2.54mm pitch. This part supports board-to-cable/wire applications in addition to board-to-board. Contact dimensions are slightly reduced (0.295" mating, 0.110" post), and the insulation color is natural rather than black. Operating temperature range is -55°C ~ 105°C with 250VAC voltage rating. ROHS3 compliance applies. Product status is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the 77311-122-13LF directly replace the 77311-122-13?

A: Yes. The 77311-122-13LF is the direct equivalent from Amphenol ICC with identical mechanical and electrical specifications. The primary difference is active product status and RoHS compliance. The LF designation indicates lead-free termination on the post contact.

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

A: The 3M 2300 series headers (2313-6211-TG and 2313-6211-TP) maintain the 13-position, 2.54mm pitch requirement but feature glass-filled thermoplastic insulation and slightly longer mating contact length (0.318" vs. 0.305"). Both 3M parts support board-to-board or cable applications. The TG variant has gold mating finish and RoHS compliance; the TP variant has tin-lead mating finish and RoHS non-compliance.

Q: Is the TE Connectivity 4-644456-3 a suitable substitute?

A: The 4-644456-3 maintains the 13-position, 2.54mm pitch configuration and supports board-to-cable/wire applications. Contact dimensions are slightly reduced, and the insulation color is natural. This part is classified as obsolete. Substitution is possible when application requirements accommodate the dimensional and material variations.

Q: What compliance considerations apply to these parts?

A: The 77311-122-13 is RoHS non-compliant. The 77311-122-13LF and 2313-6211-TG are RoHS compliant. The 2313-6211-TP is RoHS non-compliant. The 4-644456-3 is ROHS3 compliant. Selection depends on regulatory requirements for the end application.

Q: Are there operating temperature differences between substitutes?

A: Yes. The 77311-122-13LF operates from -65°C to 125°C. The 3M 2300 series and TE Connectivity MTA-100 series operate from -55°C to 105°C. The original 77311-122-13 does not specify an operating temperature range. Application temperature requirements determine which substitute is appropriate.

Q: What is the current rating for each part?

A: The 77311-122-13LF is rated at 3A per contact. The 3M 2300 series parts are rated at 3A. The TE Connectivity 4-644456-3 current rating varies by wire gauge. The original 77311-122-13 does not specify a current rating.

Q: Do packaging differences affect substitution?

A: The 77311-122-13 packaging is not specified. The 77311-122-13LF, 2313-6211-TG, and 4-644456-3 are supplied in bulk packaging. The 2313-6211-TP packaging is not specified. Packaging format does not affect electrical or mechanical compatibility.
