• Pitch: Identical 0.100" (2.54mm) spacing
• Row Configuration: Both use 3-row layout with Style C
• Mounting: Both employ free-hanging (in-line) mounting
• Termination Method: Both utilize IDC termination
• Contact Finish: Both feature gold-plated contacts
• Operating Temperature: Identical -55°C ~ 125°C range
• Flammability Rating: Both meet UL94 V-0 standard
• Insulation Material: Both use polyester thermoplastic base composition
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

The 746603-4 is the designated substitute for the obsolete 75859-101. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, mounting configuration, and operating temperature range.

The primary distinction is product status: the 75859-101 is obsolete, while the 746603-4 remains in active production. Additionally, the 746603-4 achieves ROHS3 compliance, whereas the 75859-101 is RoHS non-compliant. For new designs or system upgrades, the 746603-4 is the appropriate selection. For legacy system maintenance requiring exact compatibility, the 75859-101 remains functionally equivalent where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the 746603-4 directly replace the 75859-101 in existing applications?

A: Yes. Both connectors share identical specifications for position count (96), pitch (0.100"), row configuration (3 rows, Style C), mounting type (free-hanging in-line), and termination method (IDC). Electrical and thermal performance parameters are equivalent.

Q: What is the primary reason to transition from 75859-101 to 746603-4?

A: The 75859-101 is classified as obsolete. The 746603-4 is in active production, ensuring long-term availability and supply chain continuity. Additionally, the 746603-4 meets ROHS3 compliance requirements.

Q: Are there packaging differences between these parts?

A: The 75859-101 packaging specification is not provided. The 746603-4 is supplied in tray packaging.

Q: Do both connectors support the same current rating?

A: The 75859-101 is rated for 1.5A. The current rating for the 746603-4 is not specified in the provided data. Both connectors maintain identical contact finish (gold) and insulation material properties.

Q: Are there any material composition differences?

A: Both use polyester thermoplastic insulation. The 746603-4 specifies glass-filled polyester thermoplastic, providing enhanced mechanical properties while maintaining the same flammability rating (UL94 V-0).
