FCE17B25SC400 D-Sub 25 Position Receptacle Equivalent & Substitute Parts

Part Overview

The FCE17B25SC400 is a 25 position D-Sub receptacle connector manufactured by Amphenol ICC, featuring right-angle solder termination and female socket contacts. This connector is classified as an active product with full inventory availability (987 pcs in stock). D-Sub connectors of this configuration are widely used in industrial control systems, data acquisition equipment, and legacy computing interfaces where standardized 25-pin signal distribution is required. Substitute parts become necessary when original manufacturer stock is depleted, when alternative compliance certifications are required, or when design specifications allow for compatible alternatives from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCE17B25SC400 is determined by strict alignment with the following mandatory parameters:

Critical Parameters (Must Match Exactly):

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 25
• Number of Rows: 2
• Shell Size, Connector Layout: 3 (DB, B)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Backset Spacing: 0.590" (14.99mm)
• Flange Feature: Housing/Shell (4-40)

Performance Parameters (Must Meet or Exceed):

• Current Rating: Minimum 5A
• Operating Temperature Range: Must encompass -40°C to 85°C
• Material Flammability Rating: UL94 V-0

Compliance Parameters (Must Maintain):

• Contact Finish: Gold plated
• Material Flammability: UL94 V-0
• RoHS Compliance Status

All identified substitute parts meet these critical criteria. Variations in contact finish thickness, shell material finish (tin vs. nickel plating), dielectric material composition, and extended temperature ranges represent acceptable engineering trade-offs that do not compromise functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The TE Connectivity AMPLIMITE HD-20 series parts (5747838-3, 5747838-4, 747838-4) are functionally equivalent to the FCE17B25SC400. These parts maintain identical mechanical and electrical specifications while offering enhanced current rating (6A vs. 5A) and extended operating temperature range (-55°C to 105°C vs. -40°C to 85°C). Parts 5747838-4 and 747838-4 feature thicker gold plating (30.0µin vs. 15.0µin), providing enhanced contact durability. All three TE Connectivity options carry RoHS compliance certification and are available in high inventory quantities (924–3564 pcs).

Secondary Substitute (Alternative Compliance Path):

The NorComp Inc. 183-025-213R571 provides functional equivalence with ROHS3 compliance certification. This part features nickel-plated steel shell construction and brass contact material, differing from the original phosphor bronze contacts. The extended operating temperature range (-55°C to 105°C) exceeds the original specification. This option is suitable for applications where ROHS3 certification is specifically required and where the alternative contact material is acceptable. Inventory availability is substantial (2006 pcs).

Non-Recommended Substitute:

The TE Connectivity 747838-3 carries RoHS non-compliant status and should not be selected for new designs or applications requiring RoHS certification compliance.

Flange Feature Consideration:

The TE Connectivity 5747838-6 features a mating-side female screwlock flange instead of the housing/shell flange configuration. This variant is suitable only for applications where mating-side screwlock engagement is required and where the mechanical interface differs from the original design.

Frequently Asked Questions (FAQ)

Q: Can I substitute the FCE17B25SC400 with any of the listed alternatives without PCB redesign?

A: Yes, for all TE Connectivity AMPLIMITE HD-20 series parts (5747838-3, 5747838-4, 747838-4) and the NorComp 183-025-213R571. These maintain identical mechanical footprints, backset spacing (0.590"), and flange mounting configurations. The 5747838-6 variant requires mechanical interface verification due to its mating-side screwlock feature.

Q: What is the difference between flash gold plating and 30.0µin gold plating?

A: Flash gold plating is a minimal thickness coating applied for corrosion protection and solderability. The 30.0µin (0.76µm) thickness provides enhanced contact durability and wear resistance, particularly beneficial in high-cycle mating applications. Both finishes meet signal integrity requirements for D-Sub connectors.

Q: Are the TE Connectivity substitutes rated for the same current as the original FCE17B25SC400?

A: The TE Connectivity alternatives are rated at 6A, exceeding the original 5A rating. This higher rating provides additional design margin and is fully compatible with applications designed for 5A operation.

Q: Does the extended operating temperature range of substitute parts affect compatibility?

A: No. The substitute parts with -55°C to 105°C operating ranges are fully compatible with applications specified for -40°C to 85°C. Extended temperature capability provides additional design flexibility without compromising performance within the original specification window.

Q: What is the significance of RoHS compliance status when selecting a substitute?

A: RoHS compliance is a regulatory requirement for products sold in the European Union and many other markets. The FCE17B25SC400 is RoHS Compliant. Substitute parts 5747838-3, 5747838-4, 5747838-6, and 747838-4 maintain RoHS compliance. The 747838-3 is RoHS non-compliant and should not be used in applications requiring RoHS certification. The NorComp 183-025-213R571 carries ROHS3 certification, which is an enhanced compliance standard.

Q: Can I use the NorComp 183-025-213R571 as a direct substitute despite its brass contacts instead of phosphor bronze?

A: Yes, for applications where contact material substitution is acceptable. Brass and phosphor bronze both provide adequate electrical conductivity and mechanical properties for D-Sub signal applications. The NorComp part's nickel-plated shell and brass contacts represent a valid engineering alternative with equivalent functional performance.

Q: What packaging format should I specify when ordering substitute parts?

A: The FCE17B25SC400 is supplied in standard packaging. Substitute parts are available in different packaging: NorComp 183-025-213R571 in Tray; TE Connectivity 5747838-3, 5747838-4, 5747838-6, 747838-3, and 747838-4 in Tube. Confirm packaging requirements with your procurement specification.

Q: Are all substitute parts available in equivalent inventory quantities?

A: Yes. All substitute parts maintain substantial inventory availability: NorComp 183-025-213R571 (2006 pcs), TE Connectivity 5747838-3 (3505 pcs), 5747838-4 (3564 pcs), 5747838-6 (1011 pcs), 747838-3 (1048 pcs), and 747838-4 (924 pcs). These quantities support production requirements comparable to or exceeding the original part availability (987 pcs).
