Substitute Part Grouping Explanation
Substitution of the FCC17B25SC44B is determined by strict equivalence across the following critical parameters:
Primary Substitution Criteria:
- 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
- Flange Feature: Board Side (4-40)
- Contact Type: Signal
- Material Flammability Rating: UL94 V-0
Secondary Compatibility Parameters:
- Current Rating: 5A minimum
- Operating Temperature Range: -40°C ~ 85°C minimum
- Contact Finish: Gold
- Contact Material: Phosphor Bronze
Substitute parts are grouped into two categories:
Category 1: Amphenol ICC FCE17 Series (Active Status) The FCE17B25 series represents direct parametric equivalents manufactured by the same supplier. These parts maintain identical mechanical and electrical specifications to the FCC17B25SC44B while offering active product status and RoHS compliance. Variants within this series (FCE17B25SC40B, FCE17B25SC41B, FCE17B25SC45B, FCE17B25SC48B, FCE17B25SC49B, FCE17B25SC4DB, FCE17B25SC4EB) differ only in contact form specifications and dielectric material composition (Thermoplastic, Glass Filled), which do not affect functional substitution for the specified application.
Category 2: HARTING 09663126600 and 09663126601 (Cross-Manufacturer Alternatives) These HARTING connectors provide functional equivalence with notable parameter variations. While maintaining the core 25-position D-Sub receptacle configuration with through-hole right-angle solder termination, these parts feature different backset spacing (0.409" vs. 0.590"), higher current rating (6.5A vs. 5A), extended operating temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C), and stamped contact form versus machined contacts. These differences require design verification for specific applications.

Engineering Selection Recommendations
Primary Recommendation: Amphenol ICC FCE17 Series
The FCE17B25 series represents the optimal substitution path for the obsolete FCC17B25SC44B. All variants within this series (FCE17B25SC44B, FCE17B25SC40B, FCE17B25SC41B, FCE17B25SC45B, FCE17B25SC48B, FCE17B25SC49B, FCE17B25SC4DB, FCE17B25SC4EB) maintain identical mechanical and electrical specifications while offering active product status. These parts are manufactured by the same supplier (Amphenol ICC) and provide direct form-fit-function compatibility.
Compliance Advantage: All FCE17 variants are RoHS Compliant, addressing regulatory requirements that the original FCC17B25SC44B does not meet. This compliance status is critical for new designs and procurement in regulated industries.
Inventory Availability: FCE17 series parts demonstrate consistent inventory levels ranging from 657 to 1053 units, ensuring supply chain continuity.
Secondary Recommendation: HARTING 09663126600 and 09663126601
HARTING connectors provide functional equivalence for applications where parameter variations are acceptable. These parts are suitable for designs requiring extended operating temperature ranges (-55°C ~ 125°C) or higher current capacity (6.5A). However, the following differences require design consideration:
- Backset spacing differs (0.409" vs. 0.590"), affecting PCB layout compatibility
- Flange feature differs (Housing/Shell vs. Board Side 4-40), affecting mechanical mounting
- Contact form is stamped rather than machined
- Contact finish specifications are not provided
These parts are appropriate only when design specifications explicitly accommodate the parameter variations.
Frequently Asked Questions (FAQ)
Q: Can FCE17B25SC44B directly replace FCC17B25SC44B without PCB modification?
A: Yes. The FCE17B25SC44B maintains identical mechanical dimensions, backset spacing (0.590"), flange configuration (Board Side 4-40), and electrical specifications. Direct substitution on existing PCBs is supported without layout changes.
Q: What is the difference between FCE17B25SC44B and other FCE17B25 variants?
A: All FCE17B25 variants share identical mechanical and electrical specifications. Variants differ only in contact form designation and dielectric material composition (Thermoplastic vs. Thermoplastic, Glass Filled). These differences do not affect functional performance for standard signal applications. Selection among variants depends on specific design requirements and supplier availability.
Q: Why is RoHS compliance important for this substitution?
A: The original FCC17B25SC44B is RoHS non-compliant. All FCE17 series alternatives are RoHS Compliant, meeting regulatory requirements for products sold in markets with RoHS directives. This compliance status is mandatory for new designs and procurement in regulated industries.
Q: Can HARTING 09663126600 or 09663126601 be used as direct replacements?
A: HARTING connectors provide functional equivalence but require design verification due to parameter differences. The backset spacing (0.409" vs. 0.590") differs significantly, affecting PCB layout. The flange feature differs (Housing/Shell vs. Board Side 4-40), affecting mechanical mounting. These parts are suitable only when design specifications explicitly accommodate these variations.
Q: What is the significance of backset spacing in connector selection?
A: Backset spacing determines the distance from the connector mounting surface to the contact insertion point. The FCC17B25SC44B and all FCE17 variants use 0.590" (14.99mm) backset spacing. HARTING alternatives use 0.409" (10.40mm). This parameter directly affects PCB layout and connector positioning. Mismatched backset spacing results in incompatible mating with existing cable assemblies or connector housings.
Q: Are all FCE17B25 variants available in the same packaging?
A: FCE17B25SC49B is packaged in Box format, while other FCE17B25 variants do not specify packaging. This distinction may affect procurement and handling procedures but does not impact functional performance.
Q: What is the current rating difference between FCC17B25SC44B and HARTING alternatives?
A: The FCC17B25SC44B is rated for 5A continuous current. HARTING 09663126600 and 09663126601 are rated for 6.5A. The higher HARTING rating provides additional current capacity but does not affect compatibility with designs specified for 5A operation.
Q: How does operating temperature range affect connector selection?
A: The FCC17B25SC44B and all FCE17 variants operate from -40°C to 85°C. HARTING alternatives operate from -55°C to 125°C. For applications within the -40°C to 85°C range, both options are suitable. For applications requiring extended temperature operation, HARTING connectors provide additional capability.
Q: What is the contact material difference between Amphenol and HARTING options?
A: Amphenol FCC17 and FCE17 series use Phosphor Bronze contacts. HARTING 09663126600 and 09663126601 use Copper Alloy contacts. Both materials are suitable for signal applications. Phosphor Bronze provides superior spring characteristics and contact retention, while Copper Alloy offers cost efficiency. Contact material selection depends on application-specific requirements for contact force and durability.
