Engineering Selection Recommendations
For Panel Mount Applications: HARTING 09663186500 and 09663187500 are direct panel mount equivalents. Both maintain the 25 position D-Sub configuration with IDC ribbon cable termination and UL94 V-0 flammability rating. These parts offer increased current capacity (2A vs. 1A) and ROHS3 compliance status. Selection between these two depends on packaging requirements: 09663186500 is supplied in Tray packaging, while 09663187500 is supplied in Bulk packaging.
For Free Hanging In-Line Applications: TE Connectivity AMPLIMITE HDF-20 series connectors (1658609-2, 1658612-2, 5746861-2) provide equivalent electrical performance with current ratings of 1.25A and full compliance with operating temperature specifications (-55°C to 105°C). These parts feature gold-plated contacts at 30.0µin thickness and are suitable for applications requiring in-line configuration.
Amphenol ICC DFR series connectors (L117DBFRA25S, L17DBFRA25SC309, L17DBFRB25S, L17DBFRDA25S, L17DBFRDA25SC309) offer enhanced current ratings (3A) with strain relief features and 250V voltage rating. Contact finish varies from 15.0µin to flash plating. Selection within this series depends on specific flange requirements (housing/shell unthreaded vs. cable side 4-40) and shell material preferences (steel tin-plated vs. plastic).
All substitute parts maintain UL94 V-0 flammability compliance and RoHS compliance status, ensuring regulatory alignment with the original 3M 8325-6004 specification.
Frequently Asked Questions (FAQ)
Q: Can HARTING 09663186500 or 09663187500 directly replace the 3M 8325-6004 in panel mount applications?
A: Yes. Both HARTING parts maintain panel mount configuration, 25 position D-Sub receptacle design, IDC ribbon cable termination, and UL94 V-0 flammability rating. The increased current rating (2A vs. 1A) is compatible with applications designed for the original 1A specification. The primary difference is packaging format: Tray vs. Bulk.
Q: What is the difference between TE Connectivity 1658609-2, 1658612-2, and 5746861-2?
A: All three are AMPLIMITE HDF-20 series 25 position D-Sub receptacles with identical electrical specifications (1.25A current rating, -55°C to 105°C operating range, gold plating at 30.0µin). Differences are in flange configuration and packaging: 1658609-2 features 4-40 flange and Bulk packaging; 1658612-2 features unthreaded flange and Bulk packaging; 5746861-2 features 4-40 flange and Tube packaging.
Q: Why do Amphenol ICC DFR series parts have higher current ratings (3A) than the original 3M connector (1A)?
A: Higher current ratings indicate enhanced contact design and material composition. These parts are fully compatible with applications requiring the original 1A specification, as they exceed the minimum performance requirement. The increased rating provides design margin for applications with variable load conditions.
Q: Can I substitute a free hanging in-line connector for a panel mount connector?
A: No. Mounting type is a critical mechanical parameter. Panel mount connectors are designed for direct panel installation with specific flange geometry. Free hanging in-line connectors are designed for cable-to-cable or cable-to-board applications. Mechanical compatibility requires matching mounting type to application requirements.
Q: What packaging options are available for these substitute parts?
A: Packaging varies by manufacturer and part number. Options include Tray (HARTING 09663186500, Amphenol DFR series), Bulk (HARTING 09663187500, TE Connectivity 1658609-2 and 1658612-2), and Tube (TE Connectivity 5746861-2). Packaging selection depends on inventory management, handling requirements, and application assembly processes.
Q: Are all substitute parts RoHS compliant?
A: Yes. All listed substitute parts maintain RoHS compliance status. HARTING parts are ROHS3 compliant. TE Connectivity and Amphenol ICC parts are RoHS compliant. This ensures regulatory alignment with the original 3M 8325-6004 specification for restricted substance management.
