Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCE17B25SB2DB is determined by the following critical parameters:

Mandatory Matching Parameters:

• 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
• Material Flammability Rating: UL94 V-0

Compatible Variation Parameters:

• Current Rating: 5A or higher
• Contact Finish: Gold
• Operating Temperature: Must encompass or exceed -40°C ~ 85°C
• RoHS Status: RoHS Compliant or ROHS3 Compliant
• Backset Spacing: Minor variations acceptable within mechanical tolerance
• Shell Material Finish: Steel with plating (Tin, Nickel, or Tin-Nickel)

The substitute parts listed below satisfy these criteria and are therefore electrically and mechanically compatible with the FCE17B25SB2DB for direct replacement in applications where the specified parameters are met.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended):

D25S13A4GX00LF and D25S13A4GV00LF (Amphenol ICC, Delta D Series) are the preferred substitutes for the FCE17B25SB2DB. Both parts are manufactured by the same supplier as the primary part, ensuring design continuity and supply chain consistency. These parts are RoHS Compliant, currently active in production, and feature enhanced operating temperature ranges (-55°C ~ 125°C) and higher voltage ratings (300V) compared to the primary part. The backset spacing of 0.409" (10.40mm) is mechanically compatible with the primary part's 0.405" (10.29mm) specification. Both parts maintain the required UL94 V-0 flammability rating and gold contact finish.

Secondary Substitutes (Compatible):

5745440-1 and 5745440-4 (TE Connectivity AMP Connectors, AMPLIMITE HDP-20 Series) are active, RoHS Compliant alternatives with higher current ratings (6A) and extended operating temperature ranges (-55°C ~ 105°C). These parts feature 125V voltage ratings and are suitable for applications requiring increased current capacity. The backset spacing of 0.454" (11.53mm) represents a minor mechanical variation that remains within acceptable tolerance for standard D-Sub applications.

Alternative Substitute (Conditional):

182-025-213R531 (NorComp Inc., Series 182) is an active, ROHS3 Compliant alternative with extended operating temperature range (-55°C ~ 105°C). This part features panel mount capability in addition to through-hole mounting, providing design flexibility. The backset spacing of 0.318" (8.08mm) represents a significant mechanical variation and requires verification of mechanical compatibility with the target application before selection.

Obsolete Part (Not Recommended):

745440-1 (TE Connectivity AMP Connectors) is marked as obsolete and RoHS non-compliant. This part is not recommended for new designs or applications requiring RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can D25S13A4GX00LF be used as a direct replacement for FCE17B25SB2DB?

A: Yes. Both parts are 25 position D-Sub receptacles with female sockets, right-angle solder termination, and through-hole mounting. The electrical specifications (5A current rating, gold contact finish, UL94 V-0 flammability) are compatible. The backset spacing difference of 0.004" (0.11mm) is within standard mechanical tolerance for D-Sub connectors. The D25S13A4GX00LF offers superior operating temperature range and voltage rating.

Q: What is the significance of backset spacing differences?

A: Backset spacing is the distance from the mounting flange to the rear of the connector shell. Variations in backset spacing affect the depth of connector insertion into the mating receptacle and the overall assembly geometry. The FCE17B25SB2DB has a backset spacing of 0.405" (10.29mm). Substitutes with backset spacing of 0.409" (10.40mm) (D25S13A4GX00LF, D25S13A4GV00LF) represent a 0.004" variation and are mechanically compatible. The 182-025-213R531 with 0.318" (8.08mm) and 5745440-1/5745440-4 with 0.454" (11.53mm) represent larger variations that require mechanical verification.

Q: Are there packaging differences between the primary part and substitutes?

A: Yes. The FCE17B25SB2DB packaging is not specified in the data. Most substitutes are supplied in Tray packaging (D25S13A4GX00LF, D25S13A4GV00LF, 182-025-213R531, 5745440-1, 5745440-4). Packaging differences do not affect electrical or mechanical compatibility but may impact procurement, storage, and handling procedures.

Q: Which substitute offers the widest operating temperature range?

A: D25S13A4GX00LF and D25S13A4GV00LF both offer -55°C ~ 125°C operating temperature range, which exceeds the primary part's -40°C ~ 85°C specification. This extended range provides greater design margin for applications subject to extreme environmental conditions.

Q: Is 745440-1 suitable for new designs?

A: No. The 745440-1 is marked as obsolete and RoHS non-compliant. It is not recommended for new designs or applications requiring regulatory compliance with RoHS standards.

Q: What is the difference between 5A and 6A current ratings?

A: The FCE17B25SB2DB is rated for 5A per contact. The 5745440-1 and 5745440-4 are rated for 6A per contact. The higher current rating of the TE Connectivity parts indicates greater current-carrying capacity and is suitable for applications requiring increased power delivery. The 6A rating is backward compatible with 5A applications.

Q: Can NorComp 182-025-213R531 be used in place of the Amphenol part?

A: The 182-025-213R531 is electrically compatible (25 position, female sockets, solder termination, 5A rating, UL94 V-0). However, the backset spacing of 0.318" (8.08mm) differs significantly from the primary part's 0.405" (10.29mm). Mechanical compatibility must be verified for the specific application before substitution.

Q: What does RoHS Compliant versus ROHS3 Compliant mean?

A: RoHS Compliant indicates compliance with the original Restriction of Hazardous Substances Directive. ROHS3 Compliant indicates compliance with the updated RoHS 3 Directive (2011/65/EU as amended by 2015/863/EU), which includes additional restricted substances. Both certifications meet current regulatory requirements; ROHS3 represents the more recent standard.

Q: Are all substitute parts currently in stock?

A: Inventory status varies. D25S13A4GX00LF has the highest inventory (10200 units), followed by D25S13A4GV00LF (1501 units), 182-025-213R531 (6654 units), 5745440-1 (1034 units), and 5745440-4 (958 units). The primary part FCE17B25SB2DB has 1090 units in stock. Inventory levels should be verified at the time of procurement.
