Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCE17B25PC29B are qualified based on the following critical parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

• Connector Style: D-Sub
• Connector Type: Plug, Male Pins
• Number of Positions: 25
• Number of Rows: 2
• Shell Size, Connector Layout: 3 (DB, B)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Current Rating: 5A (minimum)
• Backset Spacing: 0.590" (14.99mm)
• Material Flammability Rating: UL94 V-0
• Contact Type: Signal

Allowable Variations:

• Shell Material Finish: Steel with Tin Plated or Steel with Nickel Plated
• Contact Material: Phosphor Bronze or Brass
• Dielectric Material: Thermoplastic Glass Filled or Polyamide (PA9T) Nylon 9T
• Operating Temperature Range: May exceed the minimum requirement of -40°C ~ 85°C
• RoHS Compliance: RoHS Compliant or ROHS3 Compliant
• Contact Finish Thickness: 15.0µin or Flash

The three substitute parts listed (183-025-113R161, 183-025-113R171, 183-025-113R531) all meet these criteria and are manufactured by NorComp Inc. under the 183 series.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (183-025-113R161, 183-025-113R171, 183-025-113R531) are active products manufactured by NorComp Inc. and meet the core electrical and mechanical specifications of the FCE17B25PC29B.

Compliance Status:

• The FCE17B25PC29B carries RoHS Compliant certification
• All substitute parts carry ROHS3 Compliant certification, which represents an enhanced compliance standard
• All parts are classified under the same HTSUS code (8536.69.4040) and ECCN (EAR99)

Operating Temperature Consideration: The substitute parts operate across a wider temperature range (-55°C ~ 105°C) compared to the main part (-40°C ~ 85°C). This extended range does not create incompatibility and provides additional operational margin for applications requiring broader temperature performance.

Flange Feature Differentiation:

• 183-025-113R161 features an unthreaded housing/shell, matching the main part configuration
• 183-025-113R171 and 183-025-113R531 feature 4-40 threaded mounting holes, providing additional mechanical retention options

Contact Material Variation: The substitute parts use brass contacts instead of phosphor bronze. Both materials are acceptable for signal-level D-Sub connectors at the specified 5A current rating and maintain equivalent electrical performance characteristics.

Inventory Availability:

• FCE17B25PC29B: 791 units
• 183-025-113R161: 1605 units
• 183-025-113R171: 2139 units
• 183-025-113R531: 1392 units

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183 series parts directly replace the Amphenol FCE17B25PC29B?

A: Yes. The 183-025-113R161, 183-025-113R171, and 183-025-113R531 are direct substitutes. All three parts match the critical parameters: 25 position D-Sub plug configuration, male pins, right-angle through-hole solder termination, 5A current rating, and 0.590" backset spacing. All maintain UL94 V-0 flammability compliance.

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

A: The primary difference is the flange feature configuration. The 183-025-113R161 has an unthreaded housing/shell, identical to the main part. The 183-025-113R171 and 183-025-113R531 both feature 4-40 threaded mounting holes for enhanced mechanical retention. Additionally, 183-025-113R531 includes a board lock feature, while 183-025-113R171 includes a ground strap feature.

Q: Are there any electrical performance differences between the main part and substitutes?

A: No. All parts maintain identical electrical specifications: 5A current rating, signal-level contact type, and gold-plated contacts. The substitute parts operate across a wider temperature range (-55°C ~ 105°C versus -40°C ~ 85°C), which represents an enhancement rather than a limitation.

Q: What is the difference between tin plating and nickel plating on the shell?

A: The main part features steel with tin plating; the substitutes feature steel with nickel plating. Both finishes provide corrosion resistance suitable for D-Sub connector applications. Nickel plating offers enhanced durability in certain environmental conditions and is widely accepted as an equivalent finish for signal-level connectors.

Q: Does the contact material difference (phosphor bronze versus brass) affect compatibility?

A: No. Both phosphor bronze and brass are standard contact materials for D-Sub connectors at the 5A current rating specified. The brass contacts in the substitute parts provide equivalent electrical conductivity and mechanical performance for signal transmission applications.

Q: Which substitute part should be selected if the application requires threaded mounting?

A: Either 183-025-113R171 or 183-025-113R531 should be selected, as both feature 4-40 threaded mounting holes. The choice between these two depends on whether the board lock feature (183-025-113R531) or ground strap feature (183-025-113R171) is required for the specific application.

Q: Are all parts RoHS compliant?

A: Yes. The main part is RoHS Compliant, and all three substitute parts are ROHS3 Compliant. ROHS3 represents an updated compliance standard and does not create incompatibility with RoHS Compliant applications.

Q: What is the packaging format for the substitute parts?

A: All three NorComp substitute parts are supplied in tray packaging, suitable for automated assembly and component handling processes.
