Amphenol ICC 77311-822-10LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77311-822-10LF is an active rectangular connector header designed for through-hole board-to-board applications. This 10-position, single-row connector operates at 3A per contact and maintains performance across -65°C to 125°C. The part is RoHS compliant with UL94 V-0 flammability rating and unlimited moisture sensitivity level. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or inventory constraints exist.

Substitute Part Grouping Explanation

Substitution eligibility for the 77311-822-10LF is determined by strict alignment of the following parameters:

Connector type classification (Header)
Contact gender (Male Pin)
Position count (10 positions)
Mating pitch (0.100" / 2.54mm)
Mounting method (Through Hole)
Termination type (Solder)
Current capacity (3A per contact minimum)
Operating temperature range (must encompass or match -65°C to 125°C)
Contact finish (Gold mating surface)
RoHS compliance status
Flammability rating (UL94 V-0)

The TE Connectivity AMP Connectors part 6-146276-0 meets these core substitution criteria. Mechanical and electrical parameters align within acceptable tolerances for board-to-board header applications. Both parts share identical pitch, position count, current rating, and compliance certifications.

Engineering Selection Recommendations

Both the 77311-822-10LF and 6-146276-0 maintain active product status and full RoHS compliance. Selection between these parts should be based on the following factors:

The 77311-822-10LF supports an extended upper operating temperature of 125°C compared to the 6-146276-0 maximum of 105°C. Applications requiring sustained operation above 105°C necessitate the Amphenol ICC part.

The 6-146276-0 features breakaway capability, enabling individual position separation when required. This functionality is absent in the 77311-822-10LF.

Insulation material differs: the 77311-822-10LF uses thermoplastic while the 6-146276-0 uses Liquid Crystal Polymer (LCP). LCP provides superior dimensional stability and chemical resistance in high-temperature or chemically aggressive environments below 105°C.

Contact material composition varies: phosphor bronze in the 77311-822-10LF versus copper alloy in the 6-146276-0. Both materials support the specified 3A current rating and gold mating surface finish.

Mechanical dimensions show minor variations in contact length and insulation height. Board layout and mating connector geometry must accommodate these differences.

Frequently Asked Questions (FAQ)

Q: Can the 6-146276-0 replace the 77311-822-10LF in all applications?

A: Substitution is valid for applications operating at or below 105°C. Applications requiring sustained operation above 105°C must use the 77311-822-10LF due to its extended temperature rating to 125°C.

Q: What is the significance of the breakaway feature in the 6-146276-0?

A: The breakaway feature allows individual positions to be separated from the connector body after assembly. The 77311-822-10LF does not support this capability. Applications requiring position-level modularity must specify the TE Connectivity part.

Q: Are the contact dimensions interchangeable between these parts?

A: Contact length and insulation height differ slightly between the two parts. The 77311-822-10LF has a 0.100" insulation height while the 6-146276-0 measures 0.090". Mating connector geometry and board layout must be verified for compatibility.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant, carry UL94 V-0 flammability rating, and share identical ECCN and HTSUS classifications. Moisture sensitivity level is unlimited (MSL 1) for both.

Q: What is the current-carrying capacity of each part?

A: Both the 77311-822-10LF and 6-146276-0 are rated for 3A per contact, supporting identical current requirements in board-to-board applications.

Q: How do the insulation materials affect performance?

A: Thermoplastic (77311-822-10LF) and Liquid Crystal Polymer (6-146276-0) both achieve UL94 V-0 rating. LCP offers superior dimensional stability and chemical resistance in specific environments. Material selection should align with application-specific environmental conditions.
