68683-350 Equivalent & Substitute Parts

Part Overview

The 68683-350 is a 100-position receptacle connector manufactured by Amphenol ICC (FCI) in the Dubox™ series. This board-to-board connector features 0.100" (2.54mm) pitch, through-hole solder termination, and gold-plated mating contacts. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, repair, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 68683-350 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Connector type (Receptacle) and contact type (Female Socket)
• Position count (100 positions) and row configuration (2 rows)
• Mating pitch (0.100" / 2.54mm) and row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole) and termination type (Solder)
• Fastening mechanism (Push-Pull)
• Mating contact finish (Gold)
• Insulation material class and flammability rating (UL94 V-0)

The BCS-150-L-D-TE from Samtec Inc. satisfies all critical matching parameters, establishing it as a functional equivalent for the obsolete 68683-350. Both connectors maintain identical position counts, pitch specifications, and board-to-board configuration, enabling direct mechanical and electrical substitution in legacy applications.

Parameter Comparison

Engineering Selection Recommendations

The BCS-150-L-D-TE is the designated substitute for the obsolete 68683-350. Both connectors meet identical mechanical and electrical interface requirements for 100-position, 0.100" pitch board-to-board applications.

Compliance Considerations:

The BCS-150-L-D-TE carries ROHS3 compliance status, whereas the 68683-350 is RoHS non-compliant. For new designs or systems subject to RoHS regulatory requirements, the BCS-150-L-D-TE provides compliant sourcing. For legacy system maintenance where the original 68683-350 is being replaced, the BCS-150-L-D-TE maintains functional compatibility while offering improved regulatory alignment.

Availability:

The 68683-350 is obsolete with limited remaining inventory (644 pcs). The BCS-150-L-D-TE is active production with established supply (1100 pcs in stock), ensuring long-term availability for both immediate replacement and future procurement needs.

Frequently Asked Questions (FAQ)

Q: Can the BCS-150-L-D-TE directly replace the 68683-350 in existing assemblies?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (100), row configuration (2 rows), mounting method (through-hole), and fastening type (push-pull). The connectors are mechanically and electrically interchangeable for board-to-board applications.

Q: What are the differences in operating temperature range?

A: The 68683-350 operates from -65°C to 125°C, while the BCS-150-L-D-TE operates from -55°C to 125°C. The BCS-150-L-D-TE has a narrower lower temperature limit. For applications requiring operation below -55°C, the original 68683-350 specification must be maintained if available.

Q: How do the voltage ratings differ?

A: The 68683-350 is rated for 1000V, while the BCS-150-L-D-TE is rated for 475VAC. For applications requiring the full 1000V rating, voltage compatibility must be verified before substitution.

Q: What is the difference in insulation material?

A: The 68683-350 uses Polyphenylene Sulfide (PPS) glass-filled insulation, while the BCS-150-L-D-TE uses Liquid Crystal Polymer (LCP) glass-filled insulation. Both materials meet UL94 V-0 flammability requirements. Material selection may affect thermal and chemical resistance characteristics specific to the application environment.

Q: Are there packaging differences?

A: The 68683-350 packaging is not specified in available data. The BCS-150-L-D-TE is supplied in tube packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Does the BCS-150-L-D-TE meet RoHS requirements?

A: Yes. The BCS-150-L-D-TE is ROHS3 compliant, whereas the 68683-350 is RoHS non-compliant. For systems subject to RoHS directives, the BCS-150-L-D-TE provides compliant sourcing.
