Amphenol ICC 85759-1101 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 85759-1101 is a 96-position backplane connector receptacle with female sockets, designed for through-hole PCB mounting. This component features a 0.079" (2.00mm) pitch across 4 rows and is rated for 1A at 1000V with operating temperatures from -55°C to 105°C. The part is classified as obsolete, making identification of functional equivalents essential for legacy system maintenance and board redesigns.

Substitute Part Grouping Explanation

The substitute part 98414-S06-20ULF is identified based on the following shared electrical and mechanical parameters:

Common Substitution Criteria:

• Pitch: 0.079" (2.00mm) — identical mating pitch ensures mechanical compatibility
• Mounting Type: Through Hole — both components use through-hole PCB mounting
• Contact Finish: Gold — both utilize gold plating for mating surfaces
• Material Flammability Rating: UL94 V-0 — equivalent flame resistance classification
• Moisture Sensitivity Level: 1 (Unlimited) — identical MSL rating
• ECCN Classification: EAR99 — same export control classification
• HTSUS Code: 8536.69.4040 — identical tariff classification

Functional Differences: The 98414-S06-20ULF operates as a header connector with male pins in a 20-position, 2-row configuration, compared to the 85759-1101's 96-position receptacle with female sockets. This represents a significant reduction in position count and a change in connector gender. The substitute part is rated for 2A at 200V, providing lower voltage but higher current capacity than the original.

Parameter Comparison

Engineering Selection Recommendations

The 98414-S06-20ULF is an active product with RoHS compliance, addressing the obsolescence status of the 85759-1101. However, substitution requires careful circuit-level evaluation:

Voltage Consideration: The substitute part is rated for 200V maximum, compared to the original 1000V rating. Applications requiring voltages above 200V cannot use this substitute.

Position Count: The 20-position configuration of the substitute represents a significant reduction from the 96-position original. This substitution is only viable for applications requiring 20 or fewer signal connections.

Connector Gender: The change from receptacle (female) to header (male) requires corresponding changes to mating connectors in the system design.

Termination Method: The shift from press-fit to solder termination affects PCB assembly processes and rework procedures.

Compliance Status: The substitute's RoHS compliance may be advantageous for new designs or systems with environmental compliance requirements, though the original part's non-compliance status must be considered for legacy system compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 98414-S06-20ULF directly replace the 85759-1101 in existing designs?

A: Direct replacement is not possible due to fundamental differences in position count (20 vs. 96), connector gender (header vs. receptacle), and voltage rating (200V vs. 1000V). Substitution requires circuit redesign and mating connector changes.

Q: What is the significance of the 0.079" (2.00mm) pitch match?

A: The identical pitch ensures that both connectors use the same spacing between contact positions. This is a necessary but not sufficient condition for substitution, as other parameters including position count, connector type, and electrical ratings must also be compatible.

Q: How does the termination method difference affect PCB assembly?

A: The 85759-1101 uses press-fit termination, which requires specialized insertion tooling and does not require solder. The 98414-S06-20ULF uses solder termination, requiring standard wave or reflow soldering processes. Assembly procedures and equipment differ between these methods.

Q: Why is the substitute part rated for higher current but lower voltage?

A: Current and voltage ratings are independent electrical parameters determined by contact geometry, material composition, and insulation design. The 98414-S06-20ULF's 2A rating reflects its header pin design, while its 200V rating reflects its insulation system. These do not indicate superior overall performance for high-voltage applications.

Q: What does RoHS compliance status mean for substitution decisions?

A: RoHS compliance indicates the part meets restrictions on hazardous substances. The substitute's RoHS compliance may be required for new product designs or systems with environmental regulations, but does not affect electrical or mechanical compatibility with the original part's function.

Q: Are there any shared certifications between these parts?

A: Both parts share UL94 V-0 flammability rating, MSL 1 (Unlimited) moisture sensitivity level, and EAR99 export classification. These shared certifications indicate equivalent material safety and regulatory treatment, but do not establish functional equivalence.
