L17DBFRBA25P D-Sub 25 Position IDC Plug Connector

Part Overview

The L17DBFRBA25P is a 25 position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products) designed for IDC ribbon cable termination. This free hanging, in-line connector features male pins with a DB/B shell size (Size 3) and is rated for 3A at 250V. The connector is currently in active product status with 731 pieces in stock.

Substitute parts are necessary when specific mounting requirements, current ratings, or product availability differ from the original specification. Alternative D-Sub 25 position connectors from other manufacturers may be required to meet panel mount configurations, different flange features, or when original parts reach end-of-life status.

Engineering Selection Recommendations

Primary Equivalent (Functional Match): The A-DSF 25 LPIII/Z-UNC from Assmann WSW Components is the closest functional equivalent to the L17DBFRBA25P. Both connectors maintain identical mounting type (free hanging, in-line), current rating (3A), voltage rating (250V), and contact finish type (gold flash). Both are active products with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). This connector is suitable for direct substitution in applications requiring the same electrical and mechanical specifications.

Panel Mount Alternatives (Modified Application): The 3M 8200 series connectors (8225-6000, 8225-6003, 8225-6009, 8225-8000) are suitable substitutes only when panel mount configuration is required. These parts differ in mounting type and current rating (1A vs. 3A). Selection among these variants depends on flange feature requirements:

8225-6000 and 8225-6009: Housing/Shell (Unthreaded)
8225-6003: Housing/Shell (4-40)
8225-8000: Housing/Shell (Unthreaded)

All active 3M alternatives (8225-6000, 8225-6009, 8225-8000) carry ROHS3 compliance. The 8225-6000 and 8225-8000 are available in tray and bulk packaging respectively.

Obsolete Parts (Not Recommended): The 3M 8225-7000 and 8225-7003 are listed as obsolete products and should not be selected for new designs or applications requiring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the 3M 8225 series connectors directly replace the L17DBFRBA25P?

A: The 3M 8225 series connectors are not direct replacements due to mounting type differences. The L17DBFRBA25P is free hanging (in-line), while all 3M 8225 variants are panel mount. Additionally, 3M connectors are rated for 1A versus the 3A rating of the L17DBFRBA25P. These parts are suitable only when panel mount configuration is required and lower current capacity is acceptable for the application.

Q: What is the difference between the various 3M 8225 part numbers?

A: The 3M 8225 series variants differ primarily in flange feature configuration and packaging. The 8225-6000 and 8225-8000 feature unthreaded housing/shell flanges, while the 8225-6003 and 8225-7003 feature 4-40 threaded flanges. The 8225-6000 and 8225-6003 are supplied in tray packaging, while 8225-6009, 8225-7000, 8225-7003, and 8225-8000 are supplied in bulk packaging. Product status varies: 8225-7000 and 8225-7003 are obsolete.

Q: Is the Assmann WSW A-DSF 25 LPIII/Z-UNC a suitable substitute for the L17DBFRBA25P?

A: Yes. The A-DSF 25 LPIII/Z-UNC maintains the same mounting type (free hanging, in-line), current rating (3A), voltage rating (250V), and contact finish type (gold flash). Both connectors operate across the same temperature range (-55°C to 105°C) and meet UL94 V-0 flammability requirements. The Assmann connector is ROHS3 compliant and carries REACH Unaffected status. This connector is suitable for direct substitution in applications with identical electrical and mechanical requirements.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: connector type (plug, male pins), number of positions (25), shell size (3/DB/B), termination method (IDC ribbon cable), operating temperature range (-55°C to 105°C), and flammability rating (UL94 V-0). Mounting type, current rating, voltage rating, and flange feature configuration are variable parameters that may differ between the original part and substitutes depending on application requirements.

Q: Why does the L17DBFRBA25P have a higher current rating (3A) than the 3M 8225 series (1A)?

A: Current rating differences reflect design variations in contact material, contact geometry, and thermal characteristics. The L17DBFRBA25P uses brass contacts, while the 3M 8225 series uses copper alloy contacts. These material and design differences result in different current handling capabilities. Applications requiring 3A capacity must use connectors rated for that current level.

Q: Are there compliance differences between the L17DBFRBA25P and substitute parts?

A: The L17DBFRBA25P is RoHS Compliant. The 3M 8225 series variants are ROHS3 Compliant (8225-6000, 8225-6003, 8225-6009, 8225-8000) or RoHS Compliant (8225-7000, 8225-7003). The Assmann A-DSF 25 LPIII/Z-UNC is ROHS3 Compliant. All parts meet UL94 V-0 flammability requirements. REACH status varies: the Assmann connector is REACH Unaffected, while 3M parts show either REACH Affected, REACH Unaffected, or Vendor Undefined status.

Q: What packaging options are available for substitute connectors?

A: The L17DBFRBA25P is supplied in tray packaging. Among substitutes, the 3M 8225-6000 and 8225-6003 are available in tray packaging, while 8225-6009, 8225-7000, 8225-7003, and 8225-8000 are supplied in bulk packaging. The Assmann A-DSF 25 LPIII/Z-UNC is supplied in tray packaging. Packaging selection depends on inventory management and assembly process requirements.
