Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 77314-856 is determined by strict equivalence across the following critical parameters:

• Connector type classification (Header, Breakaway)
• Contact type (Male Pin)
• Position count and row configuration (12 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact material composition (Phosphor Bronze)
• Insulation material and flammability rating (Thermoplastic, UL94 V-0)

The substitute part 77314-856LF maintains complete electrical and mechanical compatibility with the original specification while offering active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 77314-856LF serves as the direct functional equivalent for the obsolete 77314-856. Selection of the substitute part is supported by:

• Identical electrical and mechanical interface specifications across all mating and mounting parameters
• Active product status ensuring continued availability and manufacturing support
• RoHS compliance certification, meeting current regulatory requirements for electronic component procurement
• Documented operating temperature range (-65°C ~ 130°C) and current rating (3A) providing explicit performance boundaries
• Equivalent contact finish specifications and material composition maintaining signal integrity and reliability

The transition from 77314-856 to 77314-856LF presents no functional compatibility concerns for applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Are the 77314-856 and 77314-856LF mechanically interchangeable?

A: Yes. Both parts maintain identical pitch spacing (0.100" / 2.54mm), position count (12), row configuration (2 rows), mounting type (through-hole), and overall contact geometry. Direct substitution is possible without PCB redesign.

Q: What is the significance of the "LF" suffix in the part number?

A: The "LF" designation indicates lead-free composition in the contact finish post material (tin versus tin-lead), reflecting RoHS compliance requirements. The mating contact finish (gold, GXT™) remains equivalent between both parts.

Q: Does the 77314-856LF provide electrical performance specifications?

A: The substitute part specifies a current rating of 3A and operating temperature range of -65°C ~ 130°C. These parameters define the electrical performance envelope for applications utilizing this connector header.

Q: Why is the original 77314-856 marked as obsolete?

A: Obsolete status reflects discontinuation of manufacturing and end-of-life support. The 77314-856LF provides continued access to equivalent functionality through an active product offering.

Q: Are there packaging differences between the two parts?

A: The original 77314-856 packaging is not specified in the available data. The 77314-856LF is supplied in bulk packaging format.
