Key Parameters

Substitute Part Grouping Explanation

Substitution of the 85759-1101LF is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 96 positions is the primary functional requirement
• Pitch & Row Configuration: 0.079" (2.00mm) pitch with 4-row layout ensures mechanical and electrical compatibility with mating connectors
• Mounting & Termination: Through-hole press-fit termination maintains PCB integration compatibility
• Electrical Ratings: 1A current and 1000V voltage ratings establish the electrical performance envelope
• Contact Material: Gold plating ensures signal integrity and corrosion resistance
• Compliance: RoHS compliance and MSL rating (1 - Unlimited) are required for modern supply chain acceptance

The substitute part HM1S43FEW000H6PLF meets all these criteria while offering active product status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The HM1S43FEW000H6PLF is the recommended substitute for the obsolete 85759-1101LF based on the following engineering criteria:

Functional Equivalence: Both parts are 96-position backplane receptacles with identical pitch, row configuration, and electrical ratings. The mechanical and electrical interfaces are fully compatible.

Product Status: The substitute part maintains active product status, ensuring availability, supply chain support, and manufacturer technical documentation. The main part's obsolete status creates long-term sourcing risk.

Compliance Alignment: Both parts maintain RoHS compliance and MSL-1 moisture sensitivity ratings, meeting current regulatory and manufacturing requirements without additional qualification.

Manufacturer Continuity: Both parts are manufactured by Amphenol ICC (FCI), ensuring consistent quality standards and connector family compatibility.

Frequently Asked Questions (FAQ)

Q: Can the HM1S43FEW000H6PLF directly replace the 85759-1101LF in existing designs?

A: Yes. Both parts share identical connector type, position count, pitch, row configuration, mounting method, and electrical ratings. Direct substitution is supported without design modification.

Q: Are there differences in contact plating or material specifications?

A: Both parts feature gold-plated contacts with identical current and voltage ratings. No material or plating differences affect electrical performance or compatibility.

Q: What is the primary advantage of switching to the HM1S43FEW000H6PLF?

A: The substitute part is in active production status, providing assured long-term availability and supply chain continuity. The main part's obsolete status creates sourcing uncertainty and potential discontinuation.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are RoHS compliant with MSL-1 moisture sensitivity ratings and operate across the same temperature range (-55°C to 105°C).

Q: Are there any packaging or inventory considerations?

A: Both parts are available in new original stock. Packaging specifications should be confirmed with the supplier for specific procurement requirements.
