• Number of positions: 37
• Number of rows: 2
• Shell size and layout: 4 (DC, C)
• Mounting type: Through Hole
• Termination method: Solder

Secondary Compatibility Parameters:

• Operating temperature range: -40°C to 85°C minimum
• Current rating: 5A or greater
• Voltage rating: 200V or greater
• Material flammability: UL94 V-0
• Contact finish: Gold
• Connector style: D-Sub

All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional equivalence within the defined application envelope.

Parameter Comparison

Engineering Selection Recommendations

FCE17C37SE250 (Amphenol ICC): This part represents the direct active-production equivalent to the FCC17C37SE250. It maintains identical electrical and mechanical specifications while offering RoHS compliance status. The FCE17 series supersedes the obsolete FCC17 series within the Amphenol ICC product line. Selection of this part eliminates obsolescence risk and aligns with current regulatory requirements.

628-037-220-047 (Mercury United Electronics): This substitute provides functional equivalence with extended operating temperature range (-55°C to 85°C). The part incorporates board-lock and shielding features with ROHS3 compliance. Current rating specification of 3A per contact represents a reduction from the 5A rating of the primary part; applications requiring the full 5A capacity must account for this limitation.

628-037-220-046 (Mercury United Electronics): This part maintains core D-Sub 37-position receptacle specifications with through-hole solder termination. Limited parameter documentation restricts detailed compatibility assessment; engineering review of complete datasheets is necessary for applications with stringent electrical requirements.

7-1393740-3 (TE Connectivity AMP Connectors): This AMPLIMITE HD-20 series connector provides 37-position D-Sub receptacle functionality with RoHS compliance. Incomplete parameter specification in available documentation requires direct manufacturer consultation for applications with defined voltage, current, or temperature constraints.

Frequently Asked Questions (FAQ)

Q: Can the FCC17C37SE250 be directly replaced with the FCE17C37SE250?

A: Yes. The FCE17C37SE250 maintains identical connector type, position count, shell size, mounting configuration, and termination method. Both parts operate across -40°C to 85°C with 5A current capacity and UL94 V-0 flammability rating. The FCE17 series is the active production equivalent to the obsolete FCC17 series.

Q: What is the primary difference between the FCC17C37SE250 and the 628-037-220-047?

A: The 628-037-220-047 provides extended operating temperature range (-55°C to 85°C) and includes board-lock and shielding features. However, the current rating is specified as 3A per contact, compared to 5A for the FCC17C37SE250. Applications requiring 5A capacity must evaluate whether the 3A specification meets circuit requirements.

Q: Are all substitute parts RoHS compliant?

A: The FCC17C37SE250 is RoHS non-compliant. The FCE17C37SE250, 628-037-220-047, and 7-1393740-3 are RoHS or ROHS3 compliant. The 628-037-220-046 compliance status is not specified. Applications subject to RoHS requirements should select FCE17C37SE250, 628-037-220-047, or 7-1393740-3.

Q: What mounting configurations are available among the substitute parts?

A: All listed substitutes employ through-hole mounting. The 628-037-220-047 includes board-side flange with 4-40 mounting holes, providing additional mechanical retention compared to the unthreaded housing flange of the FCC17C37SE250. PCB layout modifications may be required for this variant.

Q: Which substitute part has the most complete parameter specification?

A: The FCE17C37SE250 provides the most comprehensive parameter documentation, with all critical electrical and mechanical specifications defined. The 628-037-220-047 offers detailed specifications with extended temperature range. The 628-037-220-046 and 7-1393740-3 have incomplete parameter documentation; manufacturer datasheets must be consulted for complete technical verification.

Q: Can the 628-037-220-047 be used in applications requiring 5A current capacity?

A: The 628-037-220-047 is rated at 3A per contact. Applications requiring 5A capacity must either select an alternative part with 5A rating or reduce circuit current requirements. Direct comparison with application current specifications is necessary.
