Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCE17B25SA4DB are qualified based on the following core parameters that determine functional interchangeability:

Critical 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

Acceptable Variation Parameters:

• Current Rating: 3A to 5A per contact (all substitutes meet or exceed minimum requirements)
• Operating Temperature Range: Substitutes with extended ranges (-55°C to 105°C or higher) are acceptable
• Shell Material Finish: Steel with Tin Plated, Nickel Plated, or Tin-Nickel Plated finishes are interchangeable
• Contact Finish Thickness: Flash or 15.0µin (0.38µm) are equivalent
• Flange Feature: Housing/Shell (4-40) or Mating Side Female Screwlock (4-40) are both acceptable
• Dielectric Material: Thermoplastic variants (Glass Filled, Nylon 9T, PBT) are functionally equivalent
• Contact Material: Phosphor Bronze or Copper Alloy are acceptable

All identified substitutes maintain active product status, RoHS compliance, and identical HTSUS and ECCN classifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The parts 182-025-213R171 (NorComp Inc.) and D25S33E4GV00LF (Amphenol ICC FCI) are the most direct substitutes for the FCE17B25SA4DB. Both maintain identical core specifications including 25 positions, 2-row configuration, Shell Size 3 (DB, B), through-hole right-angle mounting, and solder termination. Both are actively produced with current RoHS compliance and UL94 V-0 flammability rating. The 182-025-213R171 offers extended operating temperature range (-55°C to 105°C) and panel mount capability. The D25S33E4GV00LF provides 5A per contact current rating matching the original specification and extended temperature range to 125°C.

Secondary Substitutes (Application-Dependent):

The parts 622-025-260-042 and 622-025-260-043 (Mercury United Electronics) are functionally equivalent with board edge mounting options and integrated board lock features. These parts operate at 3A per contact, which is acceptable for applications not requiring the full 5A rating of the original. The A-DF 25 A/KG-T2S (Assmann WSW Components) provides 250V voltage rating and extended temperature range to 105°C with board lock feature.

Compliance Verification:

All substitute parts maintain UL94 V-0 flammability rating and RoHS compliance status. The D25S33E4GX00LF variant differs from D25S33E4GV00LF only in flange feature configuration (Housing/Shell versus Mating Side Female Screwlock) and is equally suitable for applications where the housing-mounted flange is specified.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a lower current rating (3A) in place of the FCE17B25SA4DB (5A)?

A: Substitution with lower current rating parts (622-025-260-042, 622-025-260-043, A-DF 25 A/KG-T2S) is acceptable only if your application circuit does not require the full 5A per contact capacity. Verify that maximum current per contact in your design does not exceed 3A before selecting these alternatives.

Q: What is the difference between the two Mercury United Electronics parts (622-025-260-042 and 622-025-260-043)?

A: Both parts are identical except for flange feature configuration. The 622-025-260-042 has Housing/Shell (4-40) flange mounting, while 622-025-260-043 has Mating Side Female Screwlock (4-40). Select based on your mechanical mounting requirements.

Q: Are the D25S33E4GV00LF and D25S33E4GX00LF interchangeable?

A: These parts differ only in flange feature type. The D25S33E4GV00LF has Mating Side Female Screwlock (4-40), while D25S33E4GX00LF has Housing/Shell (4-40). Both are electrically and mechanically equivalent; selection depends on your specific flange mounting configuration.

Q: Does the NorComp 182-025-213R171 panel mount capability affect its use as a through-hole substitute?

A: No. The 182-025-213R171 supports multiple mounting types including panel mount and through-hole right-angle. It functions identically to the FCE17B25SA4DB in through-hole applications.

Q: What is the significance of the backset spacing difference in the A-DF 25 A/KG-T2S (0.319" versus 0.318")?

A: The 0.001" (0.02mm) difference in backset spacing is within standard manufacturing tolerance for D-Sub connectors and does not affect functional interchangeability or mating compatibility.

Q: Can I substitute the FCE17B25SA4DB with a part rated for higher temperature operation?

A: Yes. Parts with extended operating temperature ranges (182-025-213R171 to 105°C, D25S33E4GV00LF and D25S33E4GX00LF to 125°C) are fully compatible and provide additional thermal margin. This substitution introduces no compatibility issues.

Q: Are all substitute parts available in the same packaging format?

A: The FCE17B25SA4DB packaging is not specified in the provided data. Substitute parts are available in Tray packaging (182-025-213R171, 622-025-260-042, 622-025-260-043, A-DF 25 A/KG-T2S, D25S33E4GV00LF, D25S33E4GX00LF). Verify packaging requirements with your procurement specifications.

Q: Which substitute offers the best overall compatibility with the original FCE17B25SA4DB?

A: The D25S33E4GV00LF (Amphenol ICC FCI) provides the closest match with identical 5A per contact current rating, matching backset spacing (0.318"), and extended operating temperature range. Both are Amphenol products with equivalent manufacturing standards and RoHS compliance.
