Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with RoHS or ROHS3 requirements, ensuring regulatory compliance for new designs and legacy system replacements.

Primary Substitutes (Highest Compatibility):

The 182-025-213R171 (NorComp Inc.) and D25S33E4GV00LF (Amphenol ICC FCI) are direct functional equivalents. Both maintain 5A current rating matching the FCE17B25SA2DB, support the identical 0.318" backset spacing, and provide extended operating temperature ranges (-55°C to 105°C and -55°C to 125°C respectively) that encompass the original specification. Both are RoHS compliant and maintain MSL 1 rating.

Secondary Substitutes (Application-Dependent):

The 622-025-260-042 and 622-025-260-043 (Mercury United Electronics, Inc.) provide board edge mounting options with 3A per contact current rating. These parts are suitable for applications where board edge mounting is preferred and current requirements do not exceed 3A per contact. Both maintain ROHS3 compliance and MSL 1 rating.

The A-DF 25 A/KG-T2S (Assmann WSW Components) offers the highest inventory availability (6621 units) with extended temperature range (-55°C to 105°C) and includes 250V voltage rating specification. Current rating is 3A, suitable for signal-level applications.

The D25S33E4GX00LF (Amphenol ICC FCI) provides housing/shell flange mounting with 5A per contact rating and extended temperature range (-55°C to 125°C), offering the widest operational envelope among all substitutes.

Current Rating Considerations:

Applications requiring 5A per contact operation should prioritize FCE17B25SA2DB, 182-025-213R171, D25S33E4GV00LF, or D25S33E4GX00LF. Applications with signal-level current requirements (≤3A per contact) may utilize 622-025-260-042, 622-025-260-043, or A-DF 25 A/KG-T2S.

Frequently Asked Questions (FAQ)

Q: Can the 622-025-260-042 or 622-025-260-043 be used as direct replacements for the FCE17B25SA2DB?

A: These parts are mechanically and electrically compatible for applications where current per contact does not exceed 3A. The FCE17B25SA2DB is rated for 5A, while Mercury parts are rated for 3A per contact. If the application requires 5A per contact operation, these substitutes are not suitable. Both maintain identical shell size, position count, mounting type, and termination method.

Q: What is the difference between the D25S33E4GV00LF and D25S33E4GX00LF?

A: Both parts are from the Amphenol ICC (FCI) Delta D series with identical electrical specifications (5A per contact, 300V rating, -55°C to 125°C operating range). The primary difference is the flange feature: D25S33E4GV00LF has mating side female screwlock (4-40), while D25S33E4GX00LF has housing/shell (4-40) flange. Selection depends on the specific mounting requirement of the application.

Q: Are all substitute parts RoHS compliant?

A: Yes. The FCE17B25SA2DB is RoHS Compliant. All substitute parts listed are either RoHS Compliant or ROHS3 Compliant, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of the backset spacing difference between A-DF 25 A/KG-T2S (0.319") and the FCE17B25SA2DB (0.318")?

A: The backset spacing difference of 0.001" (0.02mm) is within standard manufacturing tolerance for D-Sub connectors and does not affect mechanical or electrical compatibility. Both measurements fall within the acceptable tolerance range for DB/B shell size connectors.

Q: Can I use the A-DF 25 A/KG-T2S in applications requiring 5A per contact?

A: No. The A-DF 25 A/KG-T2S is rated for 3A per contact, while the FCE17B25SA2DB is rated for 5A. For applications requiring 5A per contact operation, use the FCE17B25SA2DB, 182-025-213R171, D25S33E4GV00LF, or D25S33E4GX00LF.

Q: What packaging format are these connectors supplied in?

A: The FCE17B25SA2DB is supplied without specified packaging designation. Substitute parts are supplied in Tray packaging: 182-025-213R171, 622-025-260-042, 622-025-260-043, A-DF 25 A/KG-T2S, D25S33E4GV00LF, and D25S33E4GX00LF. Tray packaging is standard for D-Sub connectors and does not affect component functionality.

Q: Which substitute offers the widest operating temperature range?

A: The D25S33E4GV00LF and D25S33E4GX00LF both operate from -55°C to 125°C, providing the widest temperature envelope. The FCE17B25SA2DB operates from -40°C to 85°C. For applications requiring extended low-temperature operation below -40°C, the Amphenol FCI Delta D series parts are recommended.

Q: Are there any differences in contact material between the main part and substitutes?

A: The FCE17B25SA2DB uses Phosphor Bronze contacts. The 182-025-213R171 does not specify contact material. The 622-025-260-042 and 622-025-260-043 use Copper Alloy contacts. The A-DF 25 A/KG-T2S uses Copper Alloy contacts. The D25S33E4GV00LF and D25S33E4GX00LF use Phosphor Bronze contacts. All contact materials are suitable for signal-level D-Sub applications with gold plating finish.

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

A: Both finishes provide corrosion resistance for the steel shell. Tin plating (FCE17B25SA2DB, A-DF 25 A/KG-T2S) offers standard corrosion protection. Tin-nickel plating (D25S33E4GV00LF, D25S33E4GX00LF) provides enhanced corrosion resistance and is suitable for more demanding environmental conditions. Nickel plating (182-025-213R171, 622-025-260-042, 622-025-260-043) also provides robust corrosion protection. All finishes are compatible with standard D-Sub mating operations.
