Molex 0526101075 FPC Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0526101075 is a 10-position flat flexible connector (FPC) with 1.00mm pitch, designed for surface mount applications. This connector features a vertical orientation, zero insertion force (ZIF) mechanism, and slide lock retention. The part is currently active in production with 1059 units in stock.

Substitute parts are necessary when the original part becomes unavailable, when alternative packaging formats are required, or when design requirements call for different electrical or mechanical specifications within compatible parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0526101075 is determined by the following critical parameters:

Core Compatibility Parameters:

• Number of Positions: 10
• Pitch: 0.039" (1.00mm)
• Mounting Type: Surface Mount
• Connector Type: Contacts, Vertical - 1 Sided
• Termination: Solder
• Features: Zero Insertion Force (ZIF)

Acceptable Variation Parameters:

• Contact Finish: Tin Bismuth or Gold (both provide equivalent electrical performance)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) (packaging does not affect functional compatibility)
• FFC/FCB Thickness: 0.30mm to 0.33mm (minor mechanical tolerance)
• Height Above Board: 0.209" to 0.226" (within acceptable PCB clearance range)
• Locking Feature: Slide Lock or equivalent retention mechanism
• Housing Material: Polyamide or Thermoplastic variants (both UL94 V-0 rated)

Compliance Parameters:

• Material Flammability Rating: UL94 V-0 (mandatory)
• RoHS Status: ROHS3 or RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must maintain all core compatibility parameters. Variations in contact finish, packaging, and minor mechanical dimensions are acceptable provided electrical and thermal performance remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Molex 0526101033 (Cut Tape Packaging) This part is functionally identical to the main part number but is marked as obsolete. It is suitable for substitution only if inventory depletion of the primary part occurs and existing stock of 0526101033 is available. The Cut Tape packaging format may require different handling in automated assembly environments compared to Tape & Reel format.

Molex 0526101072 (Gold Contact Finish) This part maintains all core specifications of the main part with the exception of contact finish (Gold instead of Tin Bismuth). Both finishes provide equivalent electrical performance and are UL94 V-0 rated. The part is active in production with Tape & Reel packaging. Gold contact finish offers enhanced corrosion resistance in high-humidity or corrosive environments.

Amphenol ICC (FCI) SFW10S-2STE1LF and SFW10S-2STME1LF These parts are cross-manufacturer substitutes from Amphenol ICC (FCI) and are manufacturer-recommended alternatives. Both maintain the 10-position, 1.00mm pitch configuration with surface mount solder termination and ZIF mechanism. The SFW series operates across a wider temperature range (-55°C to 105°C versus unspecified for the main part) and features Tin contact finish. Height above board is 0.209" (5.30mm), which is 0.017" lower than the main part. Both parts are RoHS Compliant and carry REACH Affected status. These parts are suitable for applications requiring cross-manufacturer qualification or when Molex inventory is unavailable.

Recommendation Basis: Selection should prioritize active product status parts (0526101075, 0526101072, SFW10S-2STE1LF, SFW10S-2STME1LF) over obsolete variants. For applications with no specific environmental or performance constraints, any active substitute maintains functional compatibility. For high-reliability applications, verify that the selected substitute meets the specific compliance and certification requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0526101075 with the Amphenol ICC SFW10S series connectors?

A: Yes. Both SFW10S-2STE1LF and SFW10S-2STME1LF are manufacturer-recommended substitutes. All core parameters match: 10 positions, 1.00mm pitch, surface mount, vertical orientation, solder termination, and ZIF mechanism. Both are UL94 V-0 rated and MSL 1. The primary differences are contact finish (Tin versus Tin Bismuth), height above board (0.209" versus 0.226"), and operating temperature range. These differences do not affect functional compatibility in standard applications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for high-speed automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on individual tape segments, typically used for lower-volume assembly or manual placement. Both formats contain identical components; packaging format affects only assembly process compatibility, not electrical or mechanical performance.

Q: Why is the Molex 0526101033 marked as obsolete if it is functionally identical?

A: Product status reflects manufacturer production and support status, not functional capability. Obsolete parts may still be available from inventory but are no longer manufactured or supported by the vendor. The 0526101033 remains electrically and mechanically compatible but should be used only when primary part availability is exhausted and existing stock is accessible.

Q: Does contact finish affect electrical performance?

A: Contact finish (Tin Bismuth, Gold, or Tin) affects corrosion resistance and long-term reliability in specific environments but does not alter baseline electrical performance. All finishes specified for these parts provide equivalent conductivity and current-carrying capacity. Gold finish offers superior corrosion resistance in high-humidity or chemically aggressive environments. Tin and Tin Bismuth finishes are suitable for standard industrial and consumer applications.

Q: Are there any PCB layout considerations when substituting the Amphenol ICC SFW series?

A: The SFW series has a height above board of 0.209" (5.30mm) compared to 0.226" (5.74mm) for the Molex parts. This 0.017" difference is within typical PCB clearance tolerances but should be verified against specific board layout constraints, particularly in space-constrained designs. FFC/FCB thickness varies slightly (0.33mm for SFW versus 0.30mm for Molex), which may affect cable routing in confined spaces.

Q: What compliance certifications apply to all substitute parts?

A: All parts listed are UL94 V-0 rated for material flammability, MSL 1 (Unlimited moisture sensitivity), and RoHS compliant. The Molex parts carry ROHS3 Compliant status, while the Amphenol ICC parts carry RoHS Compliant status. The Amphenol ICC parts carry REACH Affected status, indicating they may contain substances of concern under REACH regulations. Verify specific compliance requirements for your application before final part selection.
