Substitute Part Grouping Explanation
Substitution eligibility for the FCE17B25SC280 is determined by strict equivalence across the following critical parameters:
Primary Matching Criteria:
- Connector type: D-Sub receptacle, female sockets
- Position count: 25 positions
- Shell size: 3 (DB, B)
- Mounting configuration: Through hole, right angle
- Termination: Solder
- Backset spacing: 0.590" (14.99mm)
- Flammability rating: UL94 V-0
Secondary Compatibility Factors:
- Current rating: Substitute parts must equal or exceed 5A

Engineering Selection Recommendations
Primary Substitutes (Highest Compatibility):
The TE Connectivity AMPLIMITE HD-20 series parts (5747838-3, 5747838-4, 5747838-6, 747838-3, and 747838-4) provide direct functional equivalence to the FCE17B25SC280. These parts maintain identical mechanical interfaces, electrical ratings that meet or exceed the original specification, and active product status. The 6A current rating on TE Connectivity parts exceeds the 5A requirement, providing additional design margin. All TE Connectivity RoHS-compliant variants (5747838-3, 5747838-4, 5747838-6, and 747838-4) satisfy regulatory requirements equivalent to the original part.
Secondary Substitute (Alternative Manufacturer):
The NorComp 183-025-213R571 offers functional equivalence with ROHS3 compliance certification. This part includes panel mount capability in addition to through-hole mounting, providing design flexibility. The extended operating temperature range (-55°C to 105°C) accommodates broader environmental specifications. Nickel plating on the shell differs from the tin-plated original but maintains equivalent corrosion resistance and electrical performance.
Compliance Considerations:
For applications requiring strict RoHS compliance, select from: FCE17B25SC280 (Amphenol ICC), 183-025-213R571 (NorComp), 5747838-3, 5747838-4, 5747838-6, or 747838-4 (TE Connectivity). The part 747838-3 carries RoHS non-compliant status and is unsuitable for regulated applications.
Inventory Availability:
TE Connectivity 5747838-3 maintains the highest inventory level at 3505 units. NorComp 183-025-213R571 provides 2006 units. These alternatives support supply chain continuity when primary inventory depletes.
Frequently Asked Questions (FAQ)
Q: Can the NorComp 183-025-213R571 substitute for the FCE17B25SC280 in existing PCB designs?
A: Yes. Both connectors share identical 25-position D-Sub shell size, 0.590" backset spacing, and through-hole right-angle solder termination. The NorComp part includes additional panel mount capability, which does not affect through-hole PCB compatibility. Verify that the nickel-plated shell finish meets your application's corrosion resistance requirements.
Q: What is the difference between the TE Connectivity 5747838-4 and 747838-4 parts?
A: Both parts are mechanically and electrically identical 25-position D-Sub receptacles from the AMPLIMITE HD-20 series with 6A current rating and 30.0µin gold contact finish. The primary difference is RoHS compliance status: 5747838-4 is RoHS Compliant, while 747838-4 is RoHS Compliant. Both are suitable for equivalent applications.
Q: Are all substitute parts rated for the same current as the FCE17B25SC280?
A: The FCE17B25SC280 is rated at 5A. The NorComp 183-025-213R571 matches this 5A rating. All TE Connectivity substitutes (5747838-3, 5747838-4, 5747838-6, 747838-3, and 747838-4) are rated at 6A, which exceeds the original specification and provides additional design margin.
Q: Does contact finish thickness affect connector performance?
A: Contact finish thickness variations (15.0µin, Flash, or 30.0µin) do not affect electrical performance or mechanical compatibility. All parts maintain gold plating for signal integrity. Thicker finishes (30.0µin) provide extended contact life in high-cycle mating applications.
Q: Can I use the TE Connectivity 5747838-6 with female screwlock mating side in place of the standard FCE17B25SC280?
A: Yes. The 5747838-6 maintains identical PCB-side solder termination and mechanical interface. The female screwlock feature on the mating side provides enhanced connector retention without affecting board-level compatibility. This feature is additive and does not compromise substitution.
Q: Which substitute part offers the widest operating temperature range?
A: All substitute parts (NorComp 183-025-213R571 and all TE Connectivity variants) operate from -55°C to 105°C, exceeding the FCE17B25SC280 range of -40°C to 85°C. Select any substitute for applications requiring extended temperature performance.
Q: Are packaging differences between Tube and Tray significant for component selection?
A: Packaging format (Tube for TE Connectivity and 747838 series, Tray for NorComp) affects handling and storage but does not influence electrical or mechanical performance. Select based on your assembly process requirements and inventory management procedures.
Q: What RoHS compliance status should I specify for new designs?
A: For regulatory compliance, specify parts with RoHS Compliant or ROHS3 Compliant status. Suitable options include FCE17B25SC280, 183-025-213R571, 5747838-3, 5747838-4, 5747838-6, and 747838-4. Avoid 747838-3, which carries RoHS non-compliant status.
