Molex 0711092005 Card Edge Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0711092005 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 gold-plated phosphor bronze contacts, through-hole solder termination, and operates across -40°C to 85°C. The product is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0711092005 is determined by the following critical parameters:

• Connector Type & Application: Card edge female connectors with dual-row configuration
• Position Count & Pitch: 330 positions at 0.030" (0.76mm) spacing, or functionally equivalent position/pitch combinations
• Card Thickness Compatibility: 0.062" (1.57mm) nominal thickness
• Contact Finish & Material: Gold plating with equivalent thickness (30.0µin minimum) for signal integrity and corrosion resistance
• Termination Method: Solder or press-fit termination acceptable for through-hole PCB mounting
• Operating Temperature Range: -40°C to 85°C minimum
• Compliance Requirements: RoHS and REACH compliance status

The Amphenol ICC (FCI) 10058831-110LF qualifies as a substitute based on shared mechanical envelope, electrical performance parameters, and compliance certifications, despite differences in position count and pitch specification.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 10058831-110LF is available as an active production substitute for the obsolete Molex 0711092005. Selection of this substitute is based on:

• Mechanical Compatibility: Identical card thickness (0.062"), dual-row configuration, and through-hole mounting footprint
• Electrical Performance: Equivalent gold contact finish thickness (30.0µin) and operating temperature range (-40°C to 85°C)
• Regulatory Compliance: Both components meet RoHS and REACH requirements; the substitute maintains ROHS3 compliance
• Production Status: The substitute is in active production with confirmed inventory availability (1770 pcs), whereas the original part is obsolete
• Termination Compatibility: Press-fit termination of the substitute is functionally equivalent to solder termination for through-hole applications

Design integration requires verification that the 170-position configuration of the substitute meets the electrical and mechanical requirements of the original 330-position design.

Frequently Asked Questions (FAQ)

Q: What is the primary reason the Amphenol ICC 10058831-110LF is listed as a substitute for the Molex 0711092005?

A: The Molex part is obsolete and no longer in production. The Amphenol ICC part shares critical mechanical parameters (card thickness, dual-row configuration, pitch tolerance, and through-hole mounting) and maintains equivalent electrical performance (gold contact finish, operating temperature range) while remaining in active production.

Q: Are the pitch specifications (0.030" vs. 0.029") functionally interchangeable?

A: The pitch difference of 0.001" (0.01mm) falls within standard manufacturing tolerances for card edge connectors. Both specifications are compatible with standard PCB edge card designs in this connector class.

Q: Why does the substitute have fewer positions (170 vs. 330)?

A: The Amphenol ICC 10058831-110LF is designed for MicroTCA applications, which specify a 170-position configuration. Substitution is valid only if the application circuit design requires 170 or fewer positions. Full 330-position functionality cannot be achieved with this substitute.

Q: Are the termination methods (solder vs. press-fit) interchangeable?

A: Both solder and press-fit termination methods are acceptable for through-hole PCB mounting. Press-fit termination offers advantages in automated assembly and rework capability. PCB pad design must accommodate the specific termination method selected.

Q: Do both connectors meet current regulatory requirements?

A: Yes. The Molex 0711092005 is ROHS3 compliant, and the Amphenol ICC 10058831-110LF is RoHS compliant. Both are REACH unaffected. The substitute maintains full regulatory compliance for new designs.

Q: What is the inventory status of each part?

A: The Molex 0711092005 has 1052 pcs available as new original stock. The Amphenol ICC 10058831-110LF has 1770 pcs available in tray packaging. Availability should be confirmed with the component supplier for production requirements.
