Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 68654-436 are qualified based on the following critical parameters that determine functional interchangeability:

• Connector type classification (Header)
• Contact type (Male Pin)
• Number of positions (36)
• Mating pitch (0.100" / 2.54mm)
• Number of rows (1)
• Mounting method (Through Hole)
• Termination method (Solder)
• Board-to-board style compatibility
• Unshrouded configuration
• Square contact geometry
• UL94 V-0 flammability rating
• MSL 1 moisture sensitivity

The identified substitutes—TE Connectivity AMP Connectors 3-826646-6 and Samtec Inc. TSW-136-24-L-S—meet these core electrical and mechanical criteria, enabling direct replacement in applications where the 68654-436 is specified.

Parameter Comparison

Engineering Selection Recommendations

All three connectors maintain active product status and meet the core mechanical and electrical requirements for 36-position, 2.54mm pitch through-hole header applications. The 68654-436 remains the primary specification; however, substitution is supported by equivalent dimensional and functional characteristics.

The TE Connectivity 3-826646-6 offers RoHS compliance and an extended operating temperature range of -65°C to 105°C, with a specified 5A current rating. The Samtec TSW-136-24-L-S provides ROHS3 compliance and the widest operating temperature range of -55°C to 125°C. Both substitutes feature gold-plated mating contacts and PBT insulation material, differing from the tin-plated contacts and unspecified insulation of the original part.

Selection between these parts should be based on regulatory compliance requirements, operating temperature specifications, and contact finish preferences for the target application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-826646-6 directly replace the Amphenol ICC 68654-436?

A: Yes, for applications requiring board-to-board connectivity with 36 positions at 2.54mm pitch. Both connectors share identical mating pitch, position count, row configuration, and through-hole mounting method. The TE Connectivity part offers RoHS compliance and gold-plated contacts, which may be advantageous in corrosive environments or where regulatory compliance is required.

Q: What are the key differences between the Samtec TSW-136-24-L-S and the original 68654-436?

A: The Samtec connector operates across a wider temperature range (-55°C to 125°C versus unspecified for the 68654-436) and features ROHS3 compliance. Both use phosphor bronze contact material and square contact geometry. The Samtec part includes gold plating on mating contacts and PBT insulation, whereas the original part specifies tin plating and unspecified insulation material.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: All three connectors maintain identical mating pitch (0.100" / 2.54mm), position count (36), row configuration (1), and through-hole mounting type. Mechanical compatibility is established for board-level integration. Differences in contact length and insulation height are provided in the parameter comparison table and should be evaluated against specific PCB design requirements.

Q: Which substitute part is recommended for new designs?

A: Selection depends on application requirements. The TE Connectivity 3-826646-6 is suitable for applications requiring RoHS compliance and moderate temperature ranges. The Samtec TSW-136-24-L-S is appropriate for applications with extended temperature requirements and ROHS3 compliance mandates. Both are active products with adequate inventory availability.

Q: Do the substitute parts support cable-to-board configurations?

A: The TE Connectivity 3-826646-6 and Samtec TSW-136-24-L-S both support board-to-board or cable configurations due to their breakaway or standard header design. The original 68654-436 is specified for board-to-board style only. This expanded functionality in substitutes may provide additional application flexibility.
