FCC17C37PA4DB D-Sub 37-Position Right Angle Solder Plug Connector

Part Overview

The FCC17C37PA4DB is a 37-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products) with right-angle through-hole solder termination. This connector is classified as obsolete, indicating that direct replacements or functionally equivalent alternatives are necessary for ongoing design support and procurement.

The FCC17C37PA4DB features a male pin configuration with a 2-row layout in shell size 4 (DC, C). The connector is designed for signal applications with a current rating of 5A and operates across a temperature range of -40°C to 85°C. The connector incorporates a tin-plated steel shell with gold-plated contacts and includes filter, grounding indents, and mounting bracket features.

Due to its obsolete product status, equivalent substitute parts from active manufacturers are required to maintain design continuity and ensure long-term component availability.

Primary Substitution Criteria:

Connector Type: Plug, Male Pins
Number of Positions: 37
Number of Rows: 2
Shell Size, Connector Layout: 4 (DC, C)
Mounting Type: Through Hole, Right Angle
Termination: Solder
Material Flammability Rating: UL94 V-0

Secondary Compatibility Parameters:

Current Rating: Minimum 5A
Operating Temperature Range: Must encompass -40°C to 85°C
Backset Spacing: 0.318" (8.08mm) or 0.409" (10.40mm) depending on manufacturer design

Substitute parts are grouped into two categories based on backset spacing and contact material specifications:

Group 1 (Amphenol ICC - FCE17 Series): Maintains 0.318" (8.08mm) backset spacing with phosphor bronze contacts and gold plating, offering direct mechanical and electrical compatibility with minimal design modification.

Group 2 (HARTING - Multiple Series): Utilizes 0.409" (10.40mm) backset spacing with stamped copper alloy contacts. These parts meet all core substitution criteria but require verification of board layout compatibility due to increased backset spacing.

Engineering Selection Recommendations

Primary Recommendation: FCE17C37PA4DB (Amphenol ICC)

The FCE17C37PA4DB is the preferred substitute for the obsolete FCC17C37PA4DB. This part maintains identical backset spacing (0.318" / 8.08mm), identical current rating (5A), and identical operating temperature range (-40°C to 85°C). The FCE17C37PA4DB is an active product with RoHS compliance, ensuring long-term availability and regulatory alignment. The connector shares the same shell size, mounting configuration, and termination method, requiring no design modifications for direct substitution.

Secondary Recommendation: HARTING 09654236802 or 09654626816

The HARTING parts (09654236802 and 09654626816) are suitable alternatives when design flexibility permits. Both parts feature increased current rating (6.5A) and extended operating temperature range (-55°C to 125°C), providing enhanced performance margins. However, these parts utilize 0.409" (10.40mm) backset spacing compared to the original 0.318" (8.08mm), requiring board layout verification. The HARTING parts are active products with ROHS3 compliance and REACH unaffected status.

Flange Feature Considerations:

HARTING parts are available with three flange configurations:

Unthreaded housing/shell (09654226800, 09654227800, 09654626810, 09654627810)
M3 threaded housing/shell (09654236801, 09654626815)
4-40 threaded housing/shell (09654236802, 09654626816)

Selection of flange type depends on mounting requirements. The original FCC17C37PA4DB features 4-40 board-side flange, making 09654236802 or 09654626816 the most mechanically compatible HARTING options.

Compliance Status:

All recommended substitutes meet UL94 V-0 flammability requirements. The FCE17C37PA4DB provides RoHS compliance, while HARTING parts provide ROHS3 compliance. For applications requiring RoHS compliance, FCE17C37PA4DB is the mandatory choice.

Frequently Asked Questions (FAQ)

Q: Can HARTING parts with 0.409" backset spacing directly replace the FCC17C37PA4DB with 0.318" backset spacing?

A: HARTING parts meet all core electrical and mechanical substitution criteria but feature different backset spacing. Direct PCB mounting without modification is not possible. Board layout redesign or use of adapter solutions is required. The FCE17C37PA4DB maintains identical backset spacing and is recommended for direct substitution without design changes.

Q: What is the difference between the various HARTING part numbers (09654236800, 09654236801, 09654236802)?

A: These parts are identical except for flange feature configuration. The suffix indicates the mounting flange type: 09654236800 has unthreaded housing/shell, 09654236801 has M3 threaded housing/shell, and 09654236802 has 4-40 threaded housing/shell. Selection depends on the mounting interface requirements of the application.

Q: Are HARTING parts with board lock features (09654626810, 09654626815, 09654626816) compatible with the original FCC17C37PA4DB?

A: Yes. Board lock features are additional mechanical enhancements that do not affect electrical compatibility or core mechanical fit. These parts are fully compatible with applications designed for the FCC17C37PA4DB, provided backset spacing differences are accommodated.

Q: What is the significance of the current rating difference between FCC17C37PA4DB (5A) and HARTING substitutes (6.5A)?

A: The HARTING parts have a higher current rating, indicating enhanced current-carrying capacity. This provides additional design margin and is not a compatibility issue. Applications designed for 5A operation function correctly with 6.5A-rated connectors.

Q: Does the extended operating temperature range of HARTING parts (-55°C to 125°C) versus the original (-40°C to 85°C) affect compatibility?

A: No. The extended temperature range of HARTING parts is a performance enhancement. Applications operating within the original -40°C to 85°C range function correctly with HARTING substitutes. The broader range provides additional design flexibility for future applications.

Q: Why is RoHS compliance important for connector selection?

A: RoHS compliance indicates the connector meets restrictions on hazardous substances. For new designs or applications subject to RoHS regulations, the FCE17C37PA4DB (RoHS Compliant) is required. HARTING parts provide ROHS3 compliance, which is also acceptable for regulated applications. The original FCC17C37PA4DB is RoHS non-compliant and unsuitable for new regulated designs.

Q: Can the FCC17C37PA4DB be used interchangeably with FCE17C37PA4DB in existing designs?

A: Yes. The FCE17C37PA4DB is a direct functional equivalent with identical electrical and mechanical specifications. No design modifications are required. The FCE17C37PA4DB is the recommended replacement for the obsolete FCC17C37PA4DB.

Q: What is the difference between phosphor bronze contacts (FCC17C37PA4DB, FCE17C37PA4DB) and copper alloy contacts (HARTING parts)?

A: Both contact materials are suitable for signal applications. Phosphor bronze offers specific mechanical and electrical properties, while copper alloy provides alternative performance characteristics. Both materials meet the UL94 V-0 flammability requirement and are electrically compatible for the specified 5A to 6.5A current range.
