Substitute Part Grouping Explanation

Substitute parts for the FCC17C37PC20B are classified into two categories based on substitution compatibility:

Category 1: Direct Series Substitutes (Amphenol ICC FCE17 Series)

The FCE17C37PC20B, FCE17C37PC21B, FCE17C37PC24B, FCE17C37PC25B, FCE17C37PC28B, FCE17C37PC29B, FCE17C37PC2DB, and FCE17C37PC2EB maintain identical electrical and mechanical specifications to the main part. These connectors share the following critical parameters: 37 positions, 2-row configuration, shell size 4 (DC, C), through-hole right-angle mounting, solder termination, 5A current rating, UL94 V-0 flammability rating, 0.590" backset spacing, phosphor bronze contacts with gold finish at 15.0µin thickness, thermoplastic dielectric material, and -40°C to 85°C operating temperature range. The primary distinction is product status: all FCE17 variants are active, whereas the FCC17C37PC20B is obsolete. Additionally, FCE17 series parts are RoHS compliant, compared to the non-compliant status of the main part.

Category 2: Cross-Manufacturer Substitutes (HARTING Series)

The HARTING parts 09654226800 and 09654227800 provide functional equivalence with specified parameter variations. These connectors maintain the same connector style (D-Sub), connector type (plug, male pins), position count (37), row configuration (2), shell size (4, DC, C), mounting type (through-hole, right-angle), termination method (solder), flammability rating (UL94 V-0), and MSL rating (1, Unlimited). Differences include: current rating of 6.5A versus 5A, backset spacing of 0.409" (10.40mm) versus 0.590" (14.99mm), stamped contact form versus machined, copper alloy contacts versus phosphor bronze, polybutylene terephthalate (PBT) dielectric material versus thermoplastic, and extended operating temperature range of -55°C to 125°C versus -40°C to 85°C.

Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC FCE17 Series

The FCE17C37PC20B is the direct equivalent substitute for the obsolete FCC17C37PC20B. This connector maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. The FCE17 series provides superior long-term availability and regulatory alignment. All eight FCE17 variants (FCE17C37PC20B, FCE17C37PC21B, FCE17C37PC24B, FCE17C37PC25B, FCE17C37PC28B, FCE17C37PC29B, FCE17C37PC2DB, FCE17C37PC2EB) are functionally equivalent and interchangeable for applications requiring the specified 37-position, 2-row D-Sub plug configuration with 5A current rating and -40°C to 85°C operating temperature range.

Secondary Recommendation: HARTING Cross-Manufacturer Alternatives

The HARTING parts 09654226800 and 09654227800 provide functional substitution with parameter variations. These connectors are suitable for applications where the increased current rating (6.5A versus 5A), extended operating temperature range (-55°C to 125°C versus -40°C to 85°C), and alternative dielectric material composition (PBT versus thermoplastic) are compatible with system requirements. The reduced backset spacing (0.409" versus 0.590") requires mechanical design verification to confirm PCB layout compatibility. HARTING parts carry ROHS3 compliance and REACH unaffected status, providing regulatory advantages for certain markets.

Compliance Considerations

The FCC17C37PC20B is RoHS non-compliant. All recommended substitutes are RoHS compliant or ROHS3 compliant, aligning with current regulatory requirements. The FCE17 series maintains identical electrical performance while meeting modern environmental standards. Selection of substitute parts should account for system-level compliance requirements and procurement timelines, as the main part is obsolete and subject to availability constraints.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37PC20B directly replace FCC17C37PC20B without design modifications?

A: Yes. The FCE17C37PC20B maintains identical electrical and mechanical specifications to the FCC17C37PC20B, including connector style, position count, shell size, mounting type, termination method, current rating, voltage rating, operating temperature range, contact materials, and backset spacing. Direct substitution is supported without design modifications.

Q: What is the difference between the eight FCE17 variants?

A: The FCE17C37PC20B, FCE17C37PC21B, FCE17C37PC24B, FCE17C37PC25B, FCE17C37PC28B, FCE17C37PC29B, FCE17C37PC2DB, and FCE17C37PC2EB are functionally equivalent. The alphanumeric suffix variation (20B, 21B, 24B, 25B, 28B, 29B, 2DB, 2EB) indicates manufacturing or packaging variants. All maintain identical electrical and mechanical parameters and are interchangeable for the specified application.

Q: Are HARTING parts 09654226800 and 09654227800 direct replacements?

A: HARTING parts provide functional equivalence with specified parameter variations. The backset spacing differs (0.409" versus 0.590"), requiring verification of PCB layout compatibility. Current rating is higher (6.5A versus 5A), and operating temperature range is extended (-55°C to 125°C versus -40°C to 85°C). These differences may be compatible with system requirements but require engineering evaluation.

Q: Why is the FCC17C37PC20B obsolete?

A: The FCC17C37PC20B is classified as obsolete by Amphenol ICC. The FCE17 series represents the active product line continuation, offering improved compliance certifications and long-term availability. Procurement of the obsolete part is subject to inventory constraints and supply discontinuation.

Q: What is the significance of RoHS compliance in substitute selection?

A: RoHS compliance is a regulatory requirement in many markets. The FCC17C37PC20B is RoHS non-compliant, while all recommended substitutes are RoHS compliant or ROHS3 compliant. For new designs or systems subject to RoHS regulations, substitute parts provide regulatory alignment and reduce compliance risk.

Q: Does the glass-filled dielectric material in FCE17 variants affect performance?

A: The FCE17 series uses thermoplastic with glass filling, compared to the main part's standard thermoplastic. This material enhancement improves mechanical strength and thermal stability while maintaining electrical performance within the specified operating parameters. The change is transparent to electrical function and does not affect connector compatibility.

Q: What is the backset spacing, and why does it matter for HARTING substitutes?

A: Backset spacing is the distance from the connector mounting surface to the rear of the connector body. The main part and FCE17 series specify 0.590" (14.99mm), while HARTING parts specify 0.409" (10.40mm). This difference affects PCB layout and mounting clearance. HARTING substitutes require verification that the reduced backset spacing is compatible with the target application's mechanical design.

Q: Are all substitute parts available in the same packaging?

A: Packaging information is not fully specified for all parts. The main part and FCE17 series packaging is listed as not specified. HARTING parts are supplied in bulk packaging. Procurement should confirm packaging requirements and availability with the supplier.

Q: What is the contact form difference between machined and stamped contacts?

A: The main part and FCE17 series use machined contacts, while HARTING parts use stamped contacts. Machined contacts are individually formed for precision, while stamped contacts are mass-produced from sheet material. Both contact forms meet the specified electrical requirements, but machined contacts typically provide tighter tolerances and enhanced durability in high-cycle applications.

Q: Can I mix FCE17 variants in the same assembly?

A: Yes. All FCE17 variants are functionally equivalent and interchangeable. Mixing variants within the same assembly does not affect electrical or mechanical performance, as all maintain identical specifications for the critical parameters governing connector function.
