76314-145LF Equivalent & Substitute Parts

Part Overview

The 76314-145LF is a 90-position receptacle connector manufactured by Amphenol ICC (FCI) from the BergCon® series. This through-hole, board-to-board connector features a 0.100" (2.54mm) pitch with gold-plated mating contacts and tin-plated posts. The part is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The 68683-345LF qualifies as a direct substitute for the 76314-145LF based on the following critical parameters:

Matching Parameters:

• Connector type: Receptacle with female socket contacts
• Position count: 90 positions
• Pitch specification: 0.100" (2.54mm) mating pitch
• Row configuration: 2 rows with 0.100" (2.54mm) row spacing
• Mounting method: Through-hole solder termination
• Fastening mechanism: Push-pull
• Contact finish: Gold-plated mating surface
• Flammability rating: UL94 V-0

The 68683-345LF is from the Dubox™ series and maintains active product status, providing long-term availability and supply chain continuity compared to the obsolete 76314-145LF.

Parameter Comparison

Engineering Selection Recommendations

The 68683-345LF is the appropriate substitute for the obsolete 76314-145LF. The substitute maintains all critical electrical and mechanical parameters required for direct replacement in board-to-board applications. The transition from BergCon® to Dubox™ series represents a product line evolution within Amphenol ICC (FCI), with the substitute offering active product status and improved long-term availability.

The substitute's insulation material composition (Polyphenylene Sulfide with glass fill) and contact material (Phosphor Bronze) provide equivalent performance characteristics to the original part. Both components meet UL94 V-0 flammability requirements and maintain identical pitch, row spacing, and position configurations. The RoHS compliance and REACH affected status of the substitute align with current regulatory requirements for electronic components.

Frequently Asked Questions (FAQ)

Q: Can the 68683-345LF directly replace the 76314-145LF in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (90), row configuration (2 rows), and fastening mechanism (push-pull). The through-hole solder termination and gold-plated mating contacts are equivalent between the two parts.

Q: What are the physical differences between these connectors?

A: The insulation height differs: 76314-145LF measures 0.335" (8.51mm) while 68683-345LF measures 0.276" (7.00mm). The contact post length also varies: 76314-145LF has 0.135" (3.43mm) posts compared to 0.115" (2.92mm) for 68683-345LF. These dimensional differences may affect PCB layout and mating component clearances.

Q: Are there material composition differences?

A: Yes. The 76314-145LF uses thermoplastic polyester insulation with brass contacts, while the 68683-345LF uses polyphenylene sulfide (PPS) insulation with phosphor bronze contacts. Both materials meet UL94 V-0 flammability ratings and provide equivalent electrical performance.

Q: What is the packaging format for the substitute?

A: The 68683-345LF is supplied in tube packaging, compared to the main part which has unspecified packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the substitute support the same operating temperature range?

A: The 68683-345LF specifies an operating temperature range of -65°C to 125°C. The original 76314-145LF does not provide an operating temperature specification in the available data.

Q: Are both parts RoHS compliant?

A: The 68683-345LF is explicitly RoHS compliant and REACH affected. The original 76314-145LF does not provide RoHS status information in the available data.
