Engineering Selection Recommendations

Direct Plug Equivalents (Same Connector Type):

The D25P13A4GL00LF, D25P13A4GV00LF, D25P13A4GX00LF, and D25P13A6GX00LF are functionally equivalent plug connectors from the Amphenol ICC (FCI) Delta D series. All four parts maintain the 25 position, 2-row, shell size 3 (DB, B) configuration with through-hole right-angle solder termination. These parts offer extended operating temperature ranges (-55°C ~ 125°C) compared to the FCE17B25PB64B and maintain UL94 V-0 flammability compliance. The D25P13A4GX00LF and D25P13A6GX00LF carry ROHS3 compliance, providing enhanced regulatory alignment for new designs. Current ratings of 5A per contact match the primary part specification.

The DBM25P500 from the DM HE501 series provides higher current capacity (7.5A per contact) and extended temperature range (-55°C ~ 125°C) but carries RoHS non-compliant status, limiting its use in regulated applications.

Mating Receptacle Options:

The DBM25S300 and DLS3XS6AK44X are receptacle connectors (female sockets) suitable for mating with plug configurations. The DBM25S300 offers 7.5A per contact capacity and extended temperature range but is RoHS non-compliant. The DLS3XS6AK44X from Amphenol CONEC provides ROHS3 compliance and board lock features but operates at reduced current capacity (3A) and slightly lower maximum temperature (105°C).

Compliance Considerations:

For new designs requiring RoHS compliance, select from D25P13A4GL00LF, D25P13A4GV00LF, D25P13A4GX00LF, D25P13A6GX00LF, or DLS3XS6AK44X. For legacy or non-regulated applications, DBM25P500 and DBM25S300 remain viable options with superior current handling.

Frequently Asked Questions (FAQ)

Q: Can D25P13A4GL00LF directly replace FCE17B25PB64B in existing designs?

A: Yes. Both are 25 position D-Sub plugs with identical shell size 3 (DB, B) configuration, through-hole right-angle mounting, and solder termination. The D25P13A4GL00LF maintains 5A per contact current rating and gold contact finish. The extended operating temperature range (-55°C ~ 125°C) provides additional margin beyond the FCE17B25PB64B specification (-40°C ~ 85°C).

Q: What is the difference between D25P13A4GV00LF and D25P13A4GX00LF?

A: Both are Delta D series 25 position D-Sub plugs with identical electrical and mechanical specifications. The primary difference is the flange feature: D25P13A4GV00LF includes mating side female screwlock (4-40), while D25P13A4GX00LF includes housing/shell (4-40) mounting. Selection depends on the mating receptacle configuration and board layout requirements.

Q: Why is DBM25S300 listed as a substitute if it is a receptacle, not a plug?

A: DBM25S300 is included as a mating pair option for complete connector assemblies. When the FCE17B25PB64B plug is paired with a receptacle, DBM25S300 provides a compatible female socket connector from the same DM HE501 series with matching shell size 3 (DB, B) configuration and solder termination.

Q: Are there current rating differences that affect substitution?

A: Yes. The FCE17B25PB64B and D25P13A series are rated at 5A per contact. The DBM25P500 and DBM25S300 support 7.5A per contact, providing higher capacity for demanding applications. The DLS3XS6AK44X operates at 3A per contact, limiting its use to lower current applications. Current rating selection must match or exceed system requirements.

Q: What packaging options are available?

A: FCE17B25PB64B is supplied in standard packaging. D25P13A4GL00LF, D25P13A4GV00LF, D25P13A4GX00LF, and D25P13A6GX00LF are supplied in trays. DBM25P500, DBM25S300 are supplied in trays. DLS3XS6AK44X is supplied in bulk. Packaging selection affects handling, storage, and procurement logistics.

Q: Which substitute offers the best compliance for new product designs?

A: D25P13A4GX00LF and D25P13A6GX00LF carry ROHS3 compliance, and DLS3XS6AK44X carries ROHS3 compliance. These three options provide the highest regulatory alignment for new designs. All three maintain UL94 V-0 flammability rating and active product status.

Q: Can DBM25P500 be used in applications requiring RoHS compliance?

A: No. DBM25P500 is RoHS non-compliant due to yellow cadmium plating on the steel shell. For RoHS-regulated applications, select from the D25P13 series or DLS3XS6AK44X.
