Substitute Part Grouping Explanation

Substitute parts for the FCC17C37SC450 are grouped into two categories based on parametric equivalence and manufacturer source:

Category 1: Amphenol ICC FCE17 Series (Parametric Equivalents)

The FCE17C37SC450, FCE17C37SC400, FCE17C37SC410, FCE17C37SC440, FCE17C37SC480, FCE17C37SC490, FCE17C37SC4D0, and FCE17C37SC4E0 are direct parametric equivalents manufactured by Amphenol ICC. These parts maintain identical specifications across the following critical parameters:

37-position D-Sub receptacle configuration
Female socket connector type
2-row layout with Shell Size 4 (DC, C)
Through-hole, right-angle solder termination
Steel shell with tin plating
Gold contact finish at 15.0µin thickness
5A current rating
0.590" (14.99mm) backset spacing
Phosphor bronze contact material
-40°C ~ 85°C operating temperature range
UL94 V-0 flammability rating
Board Lock and Filter features
Thermoplastic dielectric material (glass-filled variant)

All FCE17 series parts are active products with RoHS compliance, distinguishing them from the obsolete, non-compliant FCC17C37SC450.

Category 2: Alternative Manufacturer Options (HARTING)

The HARTING 09644147232 and 09664127600 are similar D-Sub receptacle connectors that share the core functional architecture (37-position, 2-row, through-hole right-angle solder termination) but differ in specific electrical and mechanical parameters. These alternatives are suitable when design flexibility permits variation in backset spacing, current rating, voltage rating, contact material composition, or dielectric material type.

Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC FCE17 Series

The FCE17C37SC450, FCE17C37SC400, FCE17C37SC410, FCE17C37SC440, FCE17C37SC480, FCE17C37SC490, FCE17C37SC4D0, and FCE17C37SC4E0 are the preferred substitutes for the obsolete FCC17C37SC450. These parts maintain complete parametric equivalence across all critical electrical and mechanical specifications while offering the following advantages:

Active product status with ongoing manufacturer support
RoHS compliance, meeting current regulatory requirements
Identical connector architecture and pin configuration
Equivalent electrical performance (5A current rating, 200V voltage capability)
Identical mechanical mounting and backset spacing
Consistent contact material and finish specifications
Full compatibility with existing PCB layouts and mating connectors

The FCE17 series variants differ only in internal filter or contact configuration options, which do not affect mechanical or electrical interchangeability. Selection among FCE17C37SC400, FCE17C37SC410, FCE17C37SC440, FCE17C37SC480, FCE17C37SC490, FCE17C37SC4D0, and FCE17C37SC4E0 should be based on specific application requirements and internal connector specifications.

Secondary Recommendation: HARTING Alternatives

The HARTING 09644147232 and 09664127600 are suitable alternatives when design specifications permit the following parameter variations:

Backset spacing: 0.401" (10.20mm) or 0.409" (10.40mm) instead of 0.590" (14.99mm)
Current rating: 7.5A or 6.5A instead of 5A
Operating temperature range: -55°C ~ 125°C instead of -40°C ~ 85°C
Dielectric material: PCT or PBT-based instead of thermoplastic
Contact material: Copper alloy instead of phosphor bronze

HARTING parts are active products with ROHS3 compliance. The 09644147232 includes mounting brackets as an additional feature. These alternatives are suitable for applications where the specified parameter variations do not conflict with system requirements.

Frequently Asked Questions (FAQ)

Q1: Can FCE17C37SC450 directly replace FCC17C37SC450 without PCB modification?

Yes. The FCE17C37SC450 maintains identical mechanical dimensions, backset spacing (0.590"), shell size (4 DC, C), mounting type (through-hole right-angle), and solder termination. No PCB layout changes are required. The part is a direct drop-in replacement.

Q2: What is the difference between the various FCE17C37SC4XX variants?

All FCE17C37SC4XX variants (SC400, SC410, SC440, SC480, SC490, SC4D0, SC4E0) share identical external mechanical and electrical specifications. The suffix designations indicate internal filter or contact configuration options that do not affect mechanical interchangeability or external electrical performance. Selection should be based on specific application requirements for internal signal filtering or contact characteristics.

Q3: Why is the FCC17C37SC450 obsolete?

The FCC17C37SC450 is classified as obsolete by the manufacturer. The FCE17 series represents the current active product line from Amphenol ICC for this connector category. Obsolete status indicates that the manufacturer no longer produces or supports the FCC17 series, making transition to active alternatives necessary for long-term supply chain stability.

Q4: Are HARTING connectors compatible with Amphenol ICC mating plugs?

HARTING 09644147232 and 09664127600 share the same D-Sub 37-position, 2-row shell size 4 (DC, C) configuration as the FCC17C37SC450 and FCE17 series. However, the backset spacing differs (0.401" or 0.409" versus 0.590"), which affects the internal contact positioning. Compatibility with existing mating plugs must be verified based on the specific mating connector specifications. These HARTING parts are suitable only when mating connectors are designed for their respective backset spacing.

Q5: Does the FCE17 series meet RoHS requirements?

Yes. All FCE17C37SC4XX variants are RoHS Compliant. The original FCC17C37SC450 is RoHS non-compliant. If RoHS compliance is a regulatory requirement for your application, the FCE17 series is mandatory.

Q6: What is the significance of the contact finish thickness specification?

The contact finish thickness of 15.0µin (0.38µm) gold plating on phosphor bronze contacts ensures consistent electrical performance, corrosion resistance, and contact reliability over the connector's operational life. All Amphenol ICC FCE17 variants maintain this specification. HARTING parts do not specify contact finish thickness, indicating that contact finish specifications may differ.

Q7: Can I use HARTING 09644147232 if my application requires 200V voltage rating?

The HARTING 09644147232 specifies a 100V voltage rating, which is lower than the FCC17C37SC450 specification of 200V. Use of the HARTING part in applications requiring 200V operation is not supported by the provided specifications. The FCE17 series does not specify voltage rating but maintains parametric equivalence with the original 200V-rated part.

Q8: What is the operating temperature range difference between Amphenol ICC and HARTING options?

The FCC17C37SC450 and all FCE17 variants operate from -40°C to 85°C. HARTING 09644147232 and 09664127600 operate from -55°C to 125°C, providing extended temperature capability. Selection should be based on actual application temperature requirements.

Q9: Are there inventory considerations when selecting between substitute parts?

Yes. Current inventory levels vary across all substitute options. FCE17C37SC400 has the highest inventory (1162 Pcs), while FCE17C37SC490 has the lowest among FCE17 variants (688 Pcs). HARTING 09664127600 has 930 Pcs available. For applications requiring immediate availability or large quantities, inventory status should be considered in the selection process.

Q10: What is the difference between "Thermoplastic" and "Thermoplastic, Glass Filled" dielectric materials?

The FCC17C37SC450 uses standard thermoplastic dielectric material. All FCE17 variants use glass-filled thermoplastic, which provides enhanced mechanical strength and thermal stability. This material upgrade in the FCE17 series represents an improvement over the original design while maintaining electrical compatibility.
