Molex 0711095007 Card Edge Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0711095007 is a 330-position female card edge connector from the HiSpec 71109 series, designed for dual-edge applications with 0.030" (0.76mm) pitch spacing. This connector features through-hole solder termination, phosphor bronze contacts with gold finish, and operates across -40°C to 85°C. The product is currently obsolete, necessitating identification of functionally compatible alternatives for ongoing system support and new designs requiring equivalent performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Molex 0711095007 is determined by alignment across the following critical parameters:

• Card Thickness: 0.062" (1.57mm) — mechanical fit requirement
• Number of Rows: 2 — electrical and mechanical configuration
• Operating Temperature Range: -40°C ~ 85°C — thermal performance envelope
• Contact Finish: Gold — corrosion resistance and signal integrity
• Contact Finish Thickness: 30.0µin (0.76µm) — durability specification
• Mounting Type: Through Hole — PCB assembly compatibility
• Gender: Female — mating interface requirement
• RoHS Compliance: ROHS3 Compliant — regulatory requirement

The Amphenol ICC (FCI) 10058831-110LF qualifies as a substitute based on shared mechanical envelope (0.062" card thickness, 2-row configuration), identical operating temperature range, matching contact finish specifications, through-hole mounting, and equivalent RoHS compliance status. Pitch variation (0.029" vs. 0.030") and position count reduction (170 vs. 330) represent design trade-offs acceptable within dual-edge connector substitution logic when electrical load distribution and signal integrity requirements permit.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC 10058831-110LF represents the qualified substitute for the obsolete Molex 0711095007 based on the following engineering criteria:

Regulatory Compliance: Both connectors meet RoHS requirements, with the substitute maintaining active product status and current manufacturing support. The 10058831-110LF carries RoHS Compliant certification, ensuring continued availability and supply chain stability.

Thermal Performance: Identical operating temperature range (-40°C ~ 85°C) ensures thermal envelope compatibility across all specified application conditions.

Mechanical Interface: Matching card thickness (0.062") and dual-row configuration (2 rows) preserve mechanical fit within existing PCB edge slot designs.

Contact Specifications: Gold finish at 30.0µin thickness on both connectors maintains signal integrity and corrosion resistance equivalence.

Assembly Compatibility: Through-hole mounting type is preserved. Termination method differs (solder vs. press-fit); this represents a manufacturing process change requiring PCB design review but does not affect electrical performance or mechanical fit.

Selection of the 10058831-110LF is appropriate for applications where the reduced position count (170 vs. 330) and slightly tighter pitch (0.029" vs. 0.030") align with system electrical requirements and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 10058831-110LF directly replace the Molex 0711095007 in existing designs?

A: Direct mechanical fit is supported due to matching card thickness (0.062") and dual-row configuration. However, the reduced position count (170 vs. 330) and pitch variation (0.029" vs. 0.030") require verification that the application does not depend on the full 330-position capacity or the original 0.030" pitch spacing. PCB edge slot dimensions and signal routing must be evaluated.

Q: What is the impact of the termination method change from solder to press-fit?

A: Termination method affects PCB assembly process and hole design. Solder termination (original) uses standard through-hole pads; press-fit termination (substitute) requires precision hole sizing and may involve different assembly equipment. This is a manufacturing consideration, not an electrical performance issue.

Q: Are the insulation materials functionally equivalent?

A: Both materials (LCP glass-filled vs. polyamide nylon) provide adequate electrical insulation and mechanical support across the specified operating temperature range. Material selection does not affect connector electrical performance or compatibility.

Q: Does the pitch difference (0.030" vs. 0.029") create compatibility issues?

A: Pitch difference is minimal (0.001" / 0.025mm) and reflects manufacturing tolerance evolution. Compatibility depends on whether the PCB edge slot was designed with tolerance margins accommodating this variation. Mechanical fit verification is required.

Q: Is the substitute part currently available?

A: Yes. The Amphenol ICC 10058831-110LF carries Active product status with 1770 units in stock, ensuring supply chain availability compared to the obsolete Molex part.
