FCC17B25SC40B D-Sub 25 Position Receptacle Equivalent & Substitute Parts

Part Overview

The FCC17B25SC40B is a 25 position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This through-hole, right-angle solder termination connector features female sockets with a DB/B shell size (Shell Size 3) and board-side 4-40 flange mounting. The connector is rated for 5A current at 200V and operates across the temperature range of -40°C to 85°C.

The FCC17B25SC40B is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity, ensure component availability, and support ongoing production requirements. Active alternatives from Amphenol ICC and compatible third-party manufacturers provide functional equivalence with enhanced compliance profiles and improved availability.

Engineering Selection Recommendations

Amphenol ICC FCE17 Series (Primary Recommendation)

The FCE17B25SC40B, FCE17B25SC41B, FCE17B25SC44B, FCE17B25SC45B, FCE17B25SC48B, FCE17B25SC49B, FCE17B25SC4DB, and FCE17B25SC4EB represent the direct active equivalents to the obsolete FCC17B25SC40B. All FCE17 variants maintain identical mechanical and electrical specifications, including 25 positions, 2-row configuration, through-hole right-angle mounting, 5A current rating, and UL94 V-0 flammability compliance.

The primary advantage of FCE17 series substitutes is RoHS compliance. All FCE17 variants are RoHS Compliant, whereas the original FCC17B25SC40B is RoHS non-compliant. This compliance status is critical for applications subject to RoHS directives and for long-term supply chain sustainability.

All FCE17 variants feature enhanced dielectric materials (Thermoplastic, Glass Filled) compared to the original thermoplastic formulation, providing improved mechanical and thermal stability. Inventory availability across the FCE17 series ranges from 657 to 1053 units, ensuring reliable sourcing.

HARTING 09663126600 and 09663126601 (Alternative Consideration)

The HARTING D-Sub 25 position receptacles (09663126600 and 09663126601) provide functional equivalence with notable parameter variations. Both HARTING parts maintain the core D-Sub receptacle configuration with 25 positions, 2 rows, through-hole right-angle mounting, and UL94 V-0 flammability rating.

HARTING parts offer enhanced current rating (6.5A versus 5A) and extended operating temperature range (-55°C to 125°C versus -40°C to 85°C), providing superior performance margins in demanding thermal environments. Both HARTING variants are ROHS3 Compliant.

Critical differences exist in flange configuration and backset spacing. HARTING 09663126600 features Housing/Shell (Unthreaded) flange, while 09663126601 features Housing/Shell (M3) flange. Both differ from the original 4-40 board-side flange. Backset spacing is 0.409" (10.40mm) for HARTING parts versus 0.590" (14.99mm) for the original and all Amphenol FCE17 variants. These mechanical differences require PCB redesign and are not direct drop-in replacements.

Selection Guidance

For direct drop-in replacement with no PCB modification, select from the Amphenol ICC FCE17 series. FCE17B25SC40B is the closest functional equivalent with identical specifications and flange configuration.

For applications requiring enhanced thermal performance or higher current capacity with PCB redesign capability, HARTING alternatives provide extended operating ranges and improved current ratings.

Frequently Asked Questions (FAQ)

Q: Can FCE17B25SC40B directly replace FCC17B25SC40B without PCB modification?

A: Yes. FCE17B25SC40B is a direct mechanical and electrical equivalent. Both connectors feature identical 25-position D-Sub receptacle configuration, through-hole right-angle mounting, 4-40 board-side flange, 0.590" backset spacing, 5A current rating, and UL94 V-0 flammability rating. No PCB redesign is required.

Q: What is the primary advantage of FCE17 series substitutes over the original FCC17B25SC40B?

A: The FCE17 series is RoHS Compliant, whereas FCC17B25SC40B is RoHS non-compliant. This compliance is essential for applications subject to RoHS directives and for supply chain continuity. Additionally, FCE17 variants feature glass-filled thermoplastic dielectric material, providing improved mechanical and thermal stability compared to the original thermoplastic formulation.

Q: Are all FCE17 variants electrically and mechanically identical?

A: All FCE17 variants (FCE17B25SC40B, FCE17B25SC41B, FCE17B25SC44B, FCE17B25SC45B, FCE17B25SC48B, FCE17B25SC49B, FCE17B25SC4DB, FCE17B25SC4EB) share identical electrical and mechanical specifications. Differences exist only in internal design or manufacturing process variations not reflected in the provided parameters. Selection among FCE17 variants can be based on inventory availability and packaging preferences.

Q: Why do HARTING parts have different backset spacing?

A: HARTING 09663126600 and 09663126601 feature 0.409" (10.40mm) backset spacing compared to 0.590" (14.99mm) for Amphenol parts. This difference reflects distinct mechanical design approaches and flange configurations. HARTING parts use Housing/Shell flange mounting (Unthreaded or M3) rather than board-side 4-40 flange. These mechanical differences necessitate PCB redesign and prevent direct substitution.

Q: Can HARTING parts be used as drop-in replacements?

A: No. HARTING 09663126600 and 09663126601 require PCB redesign due to different flange configurations and backset spacing. However, they provide functional equivalence for new designs requiring enhanced thermal performance (-55°C to 125°C operating range) or higher current capacity (6.5A).

Q: What is the difference between HARTING 09663126600 and 09663126601?

A: Both parts are functionally identical 25-position D-Sub receptacles with identical electrical and thermal specifications. The primary difference is flange configuration: 09663126600 features Housing/Shell (Unthreaded) flange, while 09663126601 features Housing/Shell (M3) flange. Selection depends on the specific mounting requirement in the target application.

Q: Are all substitute parts available in the same packaging?

A: Packaging varies across substitutes. Most Amphenol FCE17 variants are supplied without specified packaging, while FCE17B25SC49B is supplied in Box packaging. HARTING parts are supplied in Bulk packaging. Verify packaging requirements with procurement specifications before finalizing part selection.

Q: What is the Moisture Sensitivity Level (MSL) for all substitute parts?

A: All substitute parts, including the original FCC17B25SC40B and all FCE17 variants, have MSL 1 (Unlimited). HARTING parts also have MSL 1 (Unlimited). This classification indicates no moisture sensitivity precautions are required during storage or handling.

Q: Are all parts classified under the same HTSUS code?

A: Yes. The original FCC17B25SC40B, all Amphenol FCE17 variants, and HARTING parts are all classified under HTSUS code 8536.69.4040, confirming their classification as D-Sub connectors for tariff and trade purposes.
