FCE17B25SA6EB D-Sub 25 Position Receptacle Equivalent & Substitute Parts

Part Overview

The FCE17B25SA6EB is a 25 position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This connector features female sockets, right-angle mounting, and solder termination, designed for signal applications in through-hole PCB assemblies. The part is currently active in production with 739 units in stock inventory.

Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: 25 position count, 2-row D-Sub layout (Shell Size 3/DB-B), receptacle configuration with female sockets, right-angle mounting orientation, solder termination method, and signal contact type. Substitutes must maintain compatibility with existing PCB footprints and mating connector interfaces while meeting the same functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCE17B25SA6EB are qualified based on the following core parameters that determine functional and mechanical compatibility:

Primary Matching Criteria:

• Connector style: D-Sub
• Connector type: Receptacle with female sockets
• Position count: 25 positions
• Row configuration: 2 rows
• Shell size and layout: 3 (DB, B)
• Mounting orientation: Right angle
• Termination method: Solder
• Contact type: Signal

Secondary Compatibility Parameters:

• Backset spacing tolerance: 0.318" ± acceptable variance
• Current rating: Equal to or greater than 5A
• Material flammability: UL94 V-0 minimum
• RoHS compliance status: RoHS Compliant or ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

All identified substitute parts meet these core criteria and are therefore electrically and mechanically interchangeable with the FCE17B25SA6EB in applications requiring 25 position D-Sub receptacle connectors with right-angle solder termination.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

The parts D25S33E4GV00LF and D25S33E4GX00LF (Amphenol ICC Delta D series) provide the closest electrical and mechanical match to the FCE17B25SA6EB. Both maintain the 5A current rating, identical backset spacing, UL94 V-0 flammability rating, and RoHS compliance. These parts feature extended operating temperature ranges (-55°C to 125°C) and higher voltage ratings (300V), making them suitable for applications requiring enhanced thermal performance. The D25S33E4GV00LF includes mating-side female screwlock features, while the D25S33E4GX00LF provides housing-shell mounting options.

Compatible Substitutes (Functional Equivalence):

The 182-025-213R171 (NorComp) and A-DF 25 A/KG-T2S (Assmann WSW) connectors are functionally equivalent with matching 25 position, 2-row D-Sub configuration and solder termination. The NorComp part maintains 5A current rating and extends operating temperature to -55°C to 105°C. The Assmann part provides ROHS3 compliance and 250V voltage rating with 3A current per contact. Both parts are active products with substantial inventory availability.

Limited Current Rating Substitutes:

The 622-025-260-042 and 622-025-260-043 (Mercury United Electronics) connectors are mechanically compatible but feature reduced current ratings of 3A per contact compared to the 5A specification of the FCE17B25SA6EB. These parts are suitable for applications where current requirements do not exceed 3A per contact. Both Mercury parts include board lock and shielding features and maintain ROHS3 compliance.

Compliance Verification:

All substitute parts maintain UL94 V-0 material flammability ratings and RoHS or ROHS3 compliance status, meeting regulatory requirements equivalent to the original FCE17B25SA6EB. Moisture sensitivity levels are consistent across all qualified substitutes at MSL 1 (Unlimited) or Not Applicable, indicating no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the 622-025-260-042 or 622-025-260-043 be used as direct replacements for the FCE17B25SA6EB?

A: These Mercury parts are mechanically compatible and maintain the same 25 position D-Sub receptacle configuration. However, they feature a reduced current rating of 3A per contact compared to the 5A rating of the FCE17B25SA6EB. They are suitable substitutes only for applications where the maximum current per contact does not exceed 3A.

Q: What is the difference between the D25S33E4GV00LF and D25S33E4GX00LF?

A: Both parts are from the Amphenol ICC Delta D series with identical electrical specifications and 5A current ratings. The primary difference is the flange feature: the D25S33E4GV00LF includes mating-side female screwlock (4-40), while the D25S33E4GX00LF features housing-shell (4-40) mounting. Selection depends on the specific mounting requirements of the application.

Q: Are all substitute parts RoHS compliant?

A: Yes. The FCE17B25SA6EB is RoHS Compliant, and all identified substitute parts are either RoHS Compliant or ROHS3 Compliant, meeting equivalent regulatory standards for hazardous substance restrictions.

Q: What is the significance of the backset spacing parameter?

A: Backset spacing (0.318" or 8.08mm for the FCE17B25SA6EB) defines the distance from the mating face to the solder tail termination points. This parameter is critical for PCB footprint compatibility. The A-DF 25 A/KG-T2S has a backset spacing of 0.319" (8.10mm), which represents a 0.01mm variance and remains within acceptable tolerance for standard D-Sub footprints.

Q: Can the NorComp 182-025-213R171 be used in applications requiring the full -40°C to 85°C operating temperature range?

A: The NorComp part is rated for -55°C to 105°C, which encompasses the -40°C to 85°C range of the FCE17B25SA6EB. The NorComp part is therefore suitable for all temperature conditions specified for the original connector.

Q: What mounting options are available among the substitute parts?

A: The FCE17B25SA6EB specifies through-hole, right-angle mounting. Most substitutes (D25S33E4GV00LF, D25S33E4GX00LF, A-DF 25 A/KG-T2S) maintain identical through-hole right-angle mounting. The NorComp 182-025-213R171 adds panel mount capability, and the Mercury parts (622-025-260-042, 622-025-260-043) include board edge mounting options, providing additional flexibility for different PCB assembly configurations.

Q: Are there inventory considerations when selecting a substitute?

A: Inventory levels vary among substitute parts. The A-DF 25 A/KG-T2S (Assmann) has the highest inventory at 6,621 units, followed by D25S33E4GV00LF (3,766 units) and 622-025-260-043 (1,269 units). The FCE17B25SA6EB has 739 units in stock. Inventory availability should be considered for supply chain planning and lead time requirements.

Q: What is the difference between tin plating and tin-nickel plating on the shell?

A: The FCE17B25SA6EB features steel with tin plating, while the Amphenol Delta D series (D25S33E4GV00LF, D25S33E4GX00LF) uses steel with tin-nickel plating. Both finishes provide corrosion resistance and are suitable for signal applications. Tin-nickel plating offers enhanced durability in harsh environmental conditions. The NorComp and Mercury parts use nickel plating, which provides different corrosion resistance characteristics.
