Parameter Comparison

Engineering Selection Recommendations

All three NorComp Inc. substitute parts (183-025-113R161, 183-025-113R171, and 183-025-113R531) are active products with full regulatory compliance suitable for direct substitution with the FCE17B25PC48B.

Compliance Alignment:

• All substitute parts maintain UL94 V-0 flammability certification
• All substitute parts are ROHS3 compliant, exceeding the RoHS compliance of the main part
• All substitute parts carry REACH unaffected status
• All parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications

Operational Considerations:

• The substitute parts support an extended operating temperature range (-55°C ~ 105°C) compared to the main part (-40°C ~ 85°C), providing broader thermal application coverage
• All parts maintain 5A current rating and identical electrical specifications
• Shell material finish differs (nickel plating versus tin plating), with nickel plating offering enhanced corrosion resistance in certain environments
• Contact material differs (brass versus phosphor bronze), with both materials suitable for signal-level applications at the specified current rating

Flange Feature Differentiation:

• 183-025-113R161: Housing/shell with unthreaded flange
• 183-025-113R171: Housing/shell with 4-40 threaded flange
• 183-025-113R531: Housing/shell with 4-40 threaded flange and board lock feature

Selection between substitute parts depends on specific flange mounting requirements and mechanical retention needs within the application.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183 series connectors directly replace the Amphenol FCE17B25PC48B?

A: Yes. The NorComp 183-025-113R161, 183-025-113R171, and 183-025-113R531 connectors are direct substitutes. All maintain identical pin count (25 positions), shell size (DB-25), mounting orientation (right-angle through-hole), termination method (solder), current rating (5A), and backset spacing (0.590"). All parts are active products with current regulatory compliance.

Q: What are the differences between the three NorComp substitute options?

A: The primary differences are flange configurations and retention features. The 183-025-113R161 features an unthreaded housing/shell flange. Both 183-025-113R171 and 183-025-113R531 feature 4-40 threaded housing/shell flanges. The 183-025-113R531 includes an additional board lock feature for enhanced mechanical retention. All three maintain identical electrical specifications and contact finishes.

Q: Does the nickel plating on substitute parts affect electrical performance?

A: No. The shell material finish (nickel plating on substitute parts versus tin plating on the main part) does not affect electrical performance for signal-level applications. Both finishes provide adequate shielding and grounding continuity. Nickel plating offers enhanced corrosion resistance in certain environmental conditions.

Q: Are the substitute parts compatible with existing PCB layouts designed for the FCE17B25PC48B?

A: Yes. All substitute parts maintain identical mounting type (through-hole, right-angle), backset spacing (0.590"), and shell size (DB-25). PCB footprints and mounting hole patterns are compatible. Flange feature variations (threaded versus unthreaded) do not affect PCB-level compatibility.

Q: What is the significance of the extended operating temperature range on substitute parts?

A: The NorComp substitute parts support -55°C ~ 105°C operation, compared to -40°C ~ 85°C for the main part. This extended range provides design flexibility for applications requiring broader thermal performance. For applications within the -40°C ~ 85°C range, both main and substitute parts perform identically.

Q: Are all parts RoHS compliant?

A: Yes. The main part is RoHS compliant. All three substitute parts are ROHS3 compliant, which represents an enhanced compliance standard. All parts meet current regulatory requirements for restricted substance elimination.

Q: What contact material differences exist, and do they affect performance?

A: The main part uses phosphor bronze contacts; substitute parts use brass contacts. Both materials are suitable for signal-level applications at 5A current rating. Contact finish (gold plating) is identical across all parts, ensuring equivalent electrical performance and corrosion resistance at the contact interface.

Q: How do the dielectric materials compare?

A: The main part uses thermoplastic with glass filling; substitute parts use polyamide (PA9T) nylon 9T. Both materials meet UL94 V-0 flammability requirements and provide adequate electrical insulation for signal-level applications. Material selection does not affect electrical performance within specified operating parameters.

Q: Which substitute part should be selected for new designs?

A: Selection depends on mechanical mounting requirements. For applications requiring threaded flange mounting with board retention, the 183-025-113R531 is appropriate. For applications requiring threaded flange mounting without board lock, the 183-025-113R171 is appropriate. For applications with unthreaded flange requirements, the 183-025-113R161 is appropriate. All three are electrically and mechanically equivalent within their respective mounting configurations.
