Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full compliance with applicable regulatory standards. Selection among qualified substitutes is based on the following engineering considerations:

Primary Substitutes (Highest Compatibility):

The D25S33E4GV00LF and D25S33E4GX00LF (Amphenol ICC Delta D series) provide the closest electrical performance match with 5A per contact current rating, matching the FCE17B25SA2EB specification. Both parts feature extended operating temperature ranges (-55°C to 125°C) and maintain RoHS compliance. The D25S33E4GV00LF includes mating side female screwlock, while the D25S33E4GX00LF features housing/shell 4-40 threading. Both are suitable for direct replacement in applications requiring 5A contact current.

Secondary Substitutes (Compatible with Current Derating):

The 182-025-213R171 (NorComp) and A-DF 25 A/KG-T2S (Assmann) are qualified substitutes for applications where 5A current rating is not mandatory. The NorComp part offers panel mount capability in addition to through-hole mounting. The Assmann part provides 250V voltage rating and extended temperature range (-55°C to 105°C). Both maintain UL94 V-0 flammability rating and gold contact finish.

Substitutes with Application Constraints:

The 622-025-260-042 and 622-025-260-043 (Mercury United Electronics) are suitable for applications where 3A per contact current rating is acceptable. Both feature board edge mounting capability and shielded construction. The 622-025-260-043 includes mating side female screwlock, while the 622-025-260-042 features housing/shell 4-40 threading. These parts are appropriate for lower-current signal applications.

Compliance and Regulatory Status:

All substitute parts maintain either RoHS or ROHS3 compliance. The NorComp 182-025-213R171 carries REACH Unaffected status. The Mercury United Electronics parts (622-025-260-042 and 622-025-260-043) and Assmann A-DF 25 A/KG-T2S all carry REACH Unaffected designation. The Amphenol FCI Delta D series parts maintain REACH Unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8536.69.4040.

Frequently Asked Questions (FAQ)

Q: Can the D25S33E4GV00LF replace the FCE17B25SA2EB in all applications?

A: The D25S33E4GV00LF is a qualified substitute for applications requiring 5A per contact current rating. Both parts share identical shell size (DB/B), position count (25), row configuration (2), backset spacing (0.318"), and solder termination. The D25S33E4GV00LF features mating side female screwlock, while the FCE17B25SA2EB has housing/shell unthreaded configuration. Verify flange feature compatibility with your application before substitution.

Q: What is the difference between the 622-025-260-042 and 622-025-260-043?

A: Both Mercury United Electronics parts are identical except for flange feature configuration. The 622-025-260-042 features housing/shell 4-40 threading, while the 622-025-260-043 features mating side female screwlock (4-40). Both support 3A per contact current rating and board edge mounting. Select based on your connector mating interface requirements.

Q: Are the NorComp 182-025-213R171 and Assmann A-DF 25 A/KG-T2S suitable for high-temperature applications?

A: The Assmann A-DF 25 A/KG-T2S operates from -55°C to 105°C, exceeding the FCE17B25SA2EB range of -40°C to 85°C. The NorComp 182-025-213R171 also operates from -55°C to 105°C. Both parts are suitable for applications requiring extended temperature operation beyond the primary part specification.

Q: What is the current rating limitation for Mercury United Electronics substitutes?

A: The 622-025-260-042 and 622-025-260-043 are rated for 3A per contact, compared to the FCE17B25SA2EB rating of 5A. These substitutes are suitable for applications where total current per contact does not exceed 3A. For applications requiring 5A per contact, select the D25S33E4GV00LF, D25S33E4GX00LF, 182-025-213R171, or A-DF 25 A/KG-T2S.

Q: Do all substitute parts have the same backset spacing as the FCE17B25SA2EB?

A: Six of seven substitute parts maintain 0.318" (8.08mm) backset spacing. The Assmann A-DF 25 A/KG-T2S has 0.319" (8.10mm) backset spacing, a 0.01mm variation. This minimal difference does not affect mechanical compatibility in standard through-hole PCB applications.

Q: What packaging format are the substitute parts supplied in?

A: The FCE17B25SA2EB is supplied in standard packaging (not specified). All substitute parts are supplied in Tray packaging: NorComp 182-025-213R171, Mercury 622-025-260-042, Mercury 622-025-260-043, Assmann A-DF 25 A/KG-T2S, Amphenol FCI D25S33E4GV00LF, and Amphenol FCI D25S33E4GX00LF.

Q: Which substitute offers the highest inventory availability?

A: The Assmann A-DF 25 A/KG-T2S has the highest inventory with 6621 units in stock, followed by the Amphenol FCI D25S33E4GV00LF with 3766 units. The Mercury 622-025-260-043 has 1269 units available. All substitutes maintain adequate stock levels for production requirements.

Q: Are there voltage rating differences between the main part and substitutes?

A: The FCE17B25SA2EB does not specify a voltage rating. The Assmann A-DF 25 A/KG-T2S is rated for 250V, and the Amphenol FCI Delta D series (D25S33E4GV00LF and D25S33E4GX00LF) are rated for 300V. These voltage ratings provide additional design margin for applications requiring voltage specification.
