FCC17C37PB49B D-Sub 37-Position Right Angle Solder Plug Connector
Part Overview
The FCC17C37PB49B is a 37-position D-Sub plug connector with right-angle through-hole solder termination, manufactured by Amphenol ICC. This connector features a male pin configuration with a 4-row shell layout (Shell Size 4, DC/C designation) and is designed for signal applications requiring 5A current capacity at 200V. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring compatible D-Sub 37-position plug connectors with identical mechanical and electrical specifications.

Substitute Part Grouping Explanation
Substitution for the FCC17C37PB49B is determined by strict equivalence across the following critical parameters:
Primary Substitution Criteria:
- Connector type: Plug with male pins
- Position count: 37 positions
- Shell size and layout: 4 (DC, C)
- Mounting configuration: Through hole, right angle
- Termination method: Solder
- Current rating: 5A minimum
- Operating temperature range: -40°C to 85°C minimum
- Shell material: Steel with tin plating
- Contact material: Phosphor bronze with gold finish
- Dielectric material: Thermoplastic, glass filled
- Flange feature: Board side mounting
Substitute parts are grouped into two categories:
Category 1: Direct Series Equivalents (Amphenol ICC FCE17 Series) The FCE17C37 series represents the active production equivalent to the obsolete FCC17C37PB49B. These parts maintain identical mechanical dimensions, electrical ratings, and material specifications. The primary difference is product status (active vs. obsolete) and RoHS compliance. Multiple variants (PB40B, PB41B, PB44B, PB45B, PB48B, PB4DB, PB4EB) exist within this series, each meeting all substitution criteria.
Category 2: Cross-Manufacturer Equivalents (HARTING) HARTING part numbers 09654226800 and 09654227800 provide functional equivalence with minor parameter variations. These maintain the 37-position D-Sub plug configuration with right-angle solder termination and equivalent mechanical form factor. Differences include higher current rating (6.5A vs. 5A), extended operating temperature range (-55°C to 125°C), and stamped contact form versus machined contacts.

Engineering Selection Recommendations
Primary Recommendation: Amphenol ICC FCE17C37 Series
For direct replacement of the obsolete FCC17C37PB49B, the Amphenol ICC FCE17C37 series (variants PB49B, PB40B, PB41B, PB44B, PB45B, PB48B, PB4DB, PB4EB) provides the optimal substitution path. These parts maintain identical mechanical form factor, electrical ratings, and material specifications while offering active product status and RoHS compliance. The FCE17C37PB49B variant provides the closest part number alignment to the original specification.
Secondary Recommendation: HARTING 09654226800 / 09654227800
HARTING equivalents are suitable for applications where extended operating temperature range (-55°C to 125°C) and higher current capacity (6.5A) provide design margin. These parts maintain the 37-position D-Sub plug configuration with right-angle solder termination and equivalent mechanical mounting. The flange feature differs (housing/shell unthreaded vs. board side 4-40), requiring mechanical design verification for mounting compatibility. ROHS3 compliance status supports modern supply chain requirements.
Compliance Considerations
The original FCC17C37PB49B is RoHS non-compliant. All recommended substitutes (FCE17C37 series and HARTING parts) are RoHS compliant, supporting regulatory requirements for new designs and system updates. Amphenol ICC FCE17C37 variants offer RoHS compliance without operational parameter changes. HARTING parts provide ROHS3 compliance with extended environmental performance.
Frequently Asked Questions (FAQ)
Q: Can FCE17C37 series parts directly replace the obsolete FCC17C37PB49B?
A: Yes. The FCE17C37 series maintains identical specifications for connector type, position count, shell size, mounting configuration, termination method, current rating, voltage rating, operating temperature range, shell material, contact material, and dielectric material. The primary differences are product status (active vs. obsolete) and RoHS compliance (compliant vs. non-compliant). Mechanical and electrical compatibility is complete.
Q: What is the difference between the multiple FCE17C37 variants (PB40B, PB41B, PB44B, PB45B, PB48B, PB4DB, PB4EB)?
A: All FCE17C37 variants share identical electrical and mechanical specifications as listed in the parameter comparison table. The suffix designations (PB40B through PB4EB) represent internal manufacturing or configuration codes that do not affect functional equivalence. Selection among variants may be based on inventory availability or specific procurement requirements.
Q: Are HARTING 09654226800 and 09654227800 fully compatible with the FCC17C37PB49B?
A: HARTING parts provide functional equivalence for the 37-position D-Sub plug connector with right-angle solder termination. Electrical compatibility is confirmed (5A minimum current rating, equivalent voltage performance). Mechanical compatibility requires verification of the flange feature difference: HARTING uses housing/shell unthreaded mounting versus the original board side 4-40 threaded flange. PCB layout and mechanical mounting must be evaluated for each application.
Q: What is the significance of the contact form difference (machined vs. stamped)?
A: The FCC17C37PB49B uses machined contacts, while HARTING equivalents use stamped contacts. Both contact forms meet the specified electrical performance and current ratings. Machined contacts typically offer tighter tolerances and higher reliability in high-cycle mating applications. Stamped contacts provide cost efficiency while maintaining electrical specifications. Selection depends on application requirements for mating cycle life and contact resistance stability.
Q: Does RoHS compliance affect electrical or mechanical performance?
A: RoHS compliance addresses material composition (lead-free solder, restricted substances) and does not alter electrical ratings, mechanical dimensions, or functional performance. All RoHS-compliant substitutes maintain the original 5A current rating, 200V voltage rating, and operating temperature specifications. RoHS compliance is a regulatory and supply chain requirement, not a performance specification.
Q: Can I use HARTING parts in applications requiring the extended temperature range?
A: Yes. HARTING parts support -55°C to 125°C operating temperature, which exceeds the original -40°C to 85°C specification. Applications requiring extended temperature performance can utilize HARTING equivalents. However, the original design specification of -40°C to 85°C remains the baseline requirement; extended range provides additional margin but is not required for standard applications.
Q: What inventory status should I consider for procurement?
A: All recommended substitutes are listed as active products with current inventory availability. FCE17C37 series variants show inventory ranging from 715 to 1138 pieces. HARTING equivalents show inventory of 822 to 1047 pieces. Procurement should prioritize active product status to ensure long-term supply chain continuity and support for future system maintenance.
