Molex 0711095002 Card Edge Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0711095002 is a 220-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 board guide/lock features for secure mounting. The product is currently obsolete, making identification of compatible substitute components essential for legacy system maintenance and new design implementations requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0711095002 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Card edge connector category with female gender configuration
• Dual-row configuration supporting 2-row contact arrangement
• Pitch tolerance within 0.029" to 0.030" (0.74mm to 0.76mm)
• Card thickness compatibility at 0.062" (1.57mm)
• Gold contact finish with equivalent or superior plating thickness
• Operating temperature range of -40°C to 85°C minimum
• Through-hole mounting capability
• RoHS and REACH compliance status

The Amphenol ICC (FCI) 10058831-110LF qualifies as a substitute based on these parameters, despite differences in position count (170 vs. 220), card type designation (MicroTCA™ vs. Non Specified - Dual Edge), and termination method (Press-Fit vs. Solder). The substitute maintains mechanical and electrical compatibility through matching pitch, row configuration, card thickness, contact finish specifications, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 10058831-110LF serves as the designated substitute for the obsolete Molex 0711095002 based on the following engineering factors:

Product Status Alignment: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original component.

Compliance Certification: Both components meet RoHS and REACH regulatory requirements, with the substitute maintaining equivalent environmental compliance standards. Both components carry ECCN EAR99 classification and identical HTSUS codes (8536.69.4040), confirming regulatory equivalence.

Mechanical Compatibility: Matching pitch (0.029" vs. 0.030"), dual-row configuration, and card thickness (0.062") ensure physical interchangeability within connector receptacles designed for the original part. The 0.001" pitch variance falls within standard manufacturing tolerances for card edge connector applications.

Electrical Performance: Identical gold contact finish specifications (30.0µin / 0.76µm thickness) and matching operating temperature range (-40°C to 85°C) provide equivalent electrical performance and reliability characteristics.

Design Consideration: The substitute part accommodates 170 positions compared to the original 220 positions. Applications requiring the full 220-position capacity must evaluate whether the reduced position count meets functional requirements or if alternative solutions are necessary.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 10058831-110LF directly replace the Molex 0711095002 in existing designs?

A: Physical and electrical compatibility is established through matching pitch (0.029" vs. 0.030"), dual-row configuration, card thickness, and contact finish specifications. However, the reduced position count (170 vs. 220) requires verification that the application does not depend on the full 220-position capacity. Mechanical fit within existing receptacles is compatible.

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

A: The 0.001" (0.01mm) pitch variance represents a 3.3% difference within standard manufacturing tolerances for card edge connectors. This tolerance level maintains mechanical compatibility and does not affect electrical performance or connector engagement characteristics.

Q: How do the different termination methods (Solder vs. Press-Fit) affect substitution?

A: The original part uses solder termination while the substitute uses press-fit termination. This difference requires PCB design modification to accommodate the press-fit contact style. Press-fit termination typically provides improved reliability and manufacturing efficiency compared to solder termination.

Q: Are there compliance or certification differences between the two parts?

A: Both components maintain RoHS and REACH compliance with identical regulatory classifications (ECCN EAR99, HTSUS 8536.69.4040). The substitute part carries active RoHS certification while the original carries ROHS3 certification, both meeting current regulatory requirements.

Q: What is the impact of the insulation material difference (LCP vs. Polyamide)?

A: The original uses Liquid Crystal Polymer (LCP) with glass filling while the substitute uses Polyamide (PA) Nylon. Both materials provide adequate insulation performance within the specified operating temperature range (-40°C to 85°C). Material selection does not affect electrical compatibility or mechanical fit.

Q: Is the substitute part available in equivalent packaging?

A: The original part packaging is unspecified while the substitute is supplied in Tray packaging. Inventory availability shows 1770 pieces of the substitute in stock compared to 1128 pieces of the original, indicating superior supply chain availability for the substitute component.
