Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCE17B25PC45B are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Core Compatibility Parameters:

• Connector style (D-Sub)
• Connector type (Plug, Male Pins)
• Number of positions (25)
• Number of rows (2)
• Shell size and layout (3 / DB, B)
• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Current rating (5A)
• Backset spacing (0.590" / 14.99mm)
• Contact finish (Gold)
• Material flammability rating (UL94 V-0)

All three substitute parts (183-025-113R161, 183-025-113R171, 183-025-113R531) manufactured by NorComp Inc. meet these core compatibility requirements. Variations exist in shell material finish (nickel plated versus tin plated), flange feature design (board side versus housing/shell mounted), contact material composition (brass versus phosphor bronze), and operating temperature range. These variations do not affect the primary electrical and mechanical interface characteristics required for substitution in standard D-Sub 25 position applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (183-025-113R161, 183-025-113R171, 183-025-113R531) are actively produced and maintain RoHS compliance status. The NorComp Inc. parts carry ROHS3 compliance certification, which exceeds the RoHS Compliant status of the original FCE17B25PC45B. All substitute parts maintain UL94 V-0 flammability rating and support the required 5A current rating at the standard D-Sub 25 position configuration.

Selection Considerations Based on Provided Specifications:

The 183-025-113R161 features an unthreaded housing/shell flange, distinguishing it from the board-side mounting approach of the FCE17B25PC45B and the 4-40 threaded housing options of the 183-025-113R171 and 183-025-113R531. Mounting interface requirements determine which substitute is appropriate for a given application.

The 183-025-113R171 and 183-025-113R531 both provide 4-40 threaded housing/shell flanges. The 183-025-113R531 includes a board lock feature, while the 183-025-113R171 includes a ground strap feature. The 183-025-113R161 includes a ground strap without board lock functionality.

All substitute parts operate across a wider temperature range (-55°C ~ 105°C) compared to the original part (-40°C ~ 85°C), providing extended thermal capability for demanding environments.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183-025-113R161, 183-025-113R171, or 183-025-113R531 directly replace the Amphenol FCE17B25PC45B in existing designs?

A: Yes, all three NorComp parts are functionally compatible as direct substitutes. They maintain identical connector style, pin count (25 positions), row configuration (2 rows), shell size (DB/B size 3), mounting type (through-hole right-angle), termination method (solder), current rating (5A), and backset spacing (0.590"). The primary design consideration is the flange mounting interface. The FCE17B25PC45B uses board-side mounting with 4-40 threads. The 183-025-113R161 uses unthreaded housing/shell mounting, while the 183-025-113R171 and 183-025-113R531 use 4-40 threaded housing/shell mounting. PCB layout modifications may be required if the original design specifies board-side mounting and a housing/shell mounted substitute is selected.

Q: What is the difference between the three NorComp substitute parts?

A: The 183-025-113R161 features an unthreaded housing/shell flange and includes a ground strap. The 183-025-113R171 features a 4-40 threaded housing/shell flange and includes a ground strap. The 183-025-113R531 features a 4-40 threaded housing/shell flange and includes a board lock feature instead of a ground strap. All three maintain identical electrical specifications and operating temperature ranges.

Q: Are there differences in contact material between the original and substitute parts?

A: Yes. The FCE17B25PC45B uses phosphor bronze contacts, while all three NorComp substitutes use brass contacts. Both materials are suitable for gold-plated signal contacts in D-Sub applications. The contact finish on all parts is gold, with the original part specifying 15.0µin (0.38µm) thickness and the NorComp parts specifying flash thickness. Flash plating provides adequate corrosion protection for standard signal applications.

Q: What is the difference between tin-plated and nickel-plated shell finishes?

A: The FCE17B25PC45B features a tin-plated steel shell, while all three NorComp substitutes feature nickel-plated steel shells. Both finishes provide corrosion resistance. Nickel plating offers superior corrosion resistance in harsh environments and is the industry standard for modern D-Sub connectors. Tin plating is suitable for standard industrial applications. The choice between these finishes depends on environmental exposure requirements.

Q: Do the substitute parts support the same current rating?

A: Yes. All substitute parts maintain the 5A current rating specified for the FCE17B25PC45B. This rating applies to the connector as a whole and is not affected by the variations in shell finish, contact material, or flange design.

Q: What is the operating temperature difference between the original and substitute parts?

A: The FCE17B25PC45B operates from -40°C to 85°C. All three NorComp substitutes operate from -55°C to 105°C. The substitute parts provide extended low-temperature capability (15°C lower minimum) and extended high-temperature capability (20°C higher maximum). Applications requiring operation outside the original part's temperature range benefit from the NorComp substitutes.

Q: Are all parts RoHS compliant?

A: Yes. The FCE17B25PC45B is RoHS Compliant. All three NorComp substitutes are ROHS3 Compliant, which represents the current RoHS directive compliance standard. ROHS3 compliance includes restrictions on additional substances beyond the original RoHS requirements and is fully backward compatible with RoHS Compliant designations.

Q: What inventory levels are available for each part?

A: The FCE17B25PC45B has 608 pieces in stock. The NorComp substitutes have higher inventory availability: 183-025-113R161 has 1605 pieces, 183-025-113R171 has 2139 pieces, and 183-025-113R531 has 1392 pieces. Substitute parts offer improved supply chain availability.

Q: How do the flange features affect PCB design?

A: The FCE17B25PC45B uses board-side mounting with 4-40 threaded holes, requiring mounting holes on the PCB itself. The 183-025-113R161 uses unthreaded housing/shell mounting, which does not require threaded PCB holes. The 183-025-113R171 and 183-025-113R531 use 4-40 threaded housing/shell mounting, which also does not require threaded PCB holes. If substituting from board-side to housing/shell mounting, PCB layout modifications are necessary to accommodate the different mounting interface.
