Molex 0711095026 Card Edge Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0711095026 is a 390-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, making identification of compatible substitute components essential for legacy system maintenance and board redesigns.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Molex 0711095026 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Card thickness: 0.062" (1.57mm)
• Number of rows: 2
• Gender: Female
• Contact finish: Gold
• Contact finish thickness: 30.0µin (0.76µm)
• Mounting type: Through Hole
• Pitch tolerance: 0.030" ± acceptable variance

Secondary Considerations:

• Position count and row distribution
• Termination method compatibility with PCB assembly processes
• Insulation material thermal and mechanical properties
• RoHS and REACH compliance status

The Amphenol ICC (FCI) 10058831-111LF qualifies as a substitute based on matching card thickness, dual-row configuration, female gender, gold contact finish with equivalent thickness, through-hole mounting, and compatible pitch spacing (0.029" vs. 0.030").

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The Molex 0711095026 is obsolete, while the Amphenol ICC 10058831-111LF is active. For new designs or legacy system maintenance requiring component availability, the active status of the Amphenol ICC part provides supply chain continuity.

Compliance Alignment: Both components meet RoHS requirements. The Molex part carries ROHS3 compliance; the Amphenol ICC part is RoHS compliant. The Amphenol ICC part is REACH Affected, whereas the Molex part is REACH Unaffected. Compliance verification against specific application and regional requirements is necessary.

Termination Method Difference: The Molex 0711095026 uses solder termination; the Amphenol ICC 10058831-111LF uses press-fit termination. This difference requires PCB design and assembly process evaluation to ensure compatibility with existing manufacturing workflows.

Position Count Variance: The Molex part provides 390 positions across dual rows; the Amphenol ICC part provides 170 positions. Application-specific position requirements must be verified before substitution.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 10058831-111LF directly replace the Molex 0711095026 in existing designs?

A: Direct replacement depends on three factors: (1) whether the application requires exactly 390 positions or can function with 170 positions, (2) whether the PCB assembly process supports press-fit termination in place of solder termination, and (3) whether the MicroTCA™ card type specification aligns with the original application requirements.

Q: What is the significance of the pitch difference (0.030" vs. 0.029")?

A: The pitch values are functionally equivalent for card edge connector applications. The 0.001" (0.01mm) difference falls within standard manufacturing tolerances and does not affect mechanical or electrical compatibility for dual-row, through-hole mounted connectors with matching card thickness.

Q: Are there compliance concerns when substituting between these parts?

A: Both parts meet RoHS requirements. The Amphenol ICC part is REACH Affected while the Molex part is REACH Unaffected. Applications subject to REACH regulations must verify that the substitute part meets specific regional compliance requirements.

Q: What is the primary difference between these connectors?

A: The primary differences are product status (obsolete vs. active), position count (390 vs. 170), termination method (solder vs. press-fit), contact material (phosphor bronze vs. copper alloy), and insulation material (LCP vs. polyamide). The card thickness, pitch spacing, dual-row configuration, and gold contact finish remain compatible.

Q: Should I consider the contact material difference in my selection?

A: Both phosphor bronze and copper alloy contacts with gold finish provide equivalent electrical performance for card edge connector applications. The choice between them depends on specific application requirements for contact resistance, durability, and cost considerations.
