Both parts are manufactured by TE Connectivity within the same FCB-205 series and maintain identical functional performance characteristics for direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the FCB-205-0228L and FCB-205-0219L relays are active production parts manufactured by TE Connectivity Aerospace, Defense and Marine. Selection between these parts is based on availability and procurement considerations rather than functional differences.

The FCB-205-0228L (5-1617786-9) is the primary specification with 932 units currently in stock. The FCB-205-0219L provides an equivalent alternative with 907 units available, offering identical electrical performance and mechanical compatibility for direct substitution in through-hole PCB applications.

Both parts maintain the same compliance profile: RoHS non-compliant status, REACH Unaffected designation, EAR99 export classification, and MSL 1 moisture sensitivity rating. The identical HTSUS code (8536.41.0020) confirms tariff classification equivalence.

Selection should be based on supply chain availability, lead time requirements, and inventory status at the time of procurement.

Frequently Asked Questions (FAQ)

Q: Can FCB-205-0219L be used as a direct replacement for FCB-205-0228L in existing circuit designs?

A: Yes. Both relays are parametrically equivalent across all electrical and mechanical specifications. The FCB-205-0219L provides identical coil voltage (28VDC), contact form (DPDT), current rating (5A), timing characteristics (4ms operate/release), and operating temperature range (-70°C to 125°C). Direct substitution is supported without circuit modification.

Q: Are there differences in switching voltage specifications between these parts?

A: The FCB-205-0228L specifies maximum switching voltage of 115VAC and 28VDC. The FCB-205-0219L does not provide switching voltage data in available documentation. Both parts share identical contact material (Silver Cadmium Oxide) and current rating (5A), indicating equivalent switching capability.

Q: Do both relays have the same physical footprint for through-hole mounting?

A: Yes. Both parts feature identical mounting specifications: through-hole mounting type with PC pin termination style. PCB layout and hole spacing are compatible between the two parts.

Q: What is the significance of the different base product numbers (1617786 vs. 1617758)?

A: Base product numbers identify distinct manufacturing variants within the FCB-205 series. Despite different base numbers, both parts maintain identical electrical performance and mechanical compatibility, confirming their status as parametric equivalents.

Q: Are there compliance or regulatory differences between these relays?

A: No. Both parts share identical compliance profiles: RoHS non-compliant, REACH Unaffected, EAR99 export classification, and MSL 1 rating. Tariff classification (HTSUS 8536.41.0020) is identical.

Q: What is the coil resistance specification for both relays?

A: Both the FCB-205-0228L and FCB-205-0219L specify 500 Ohms coil resistance with 56 mA coil current at 28VDC nominal operation. Must operate voltage is 18VDC and must release voltage is 1.5VDC for both parts.

Q: Can these relays be used in aerospace and defense applications?

A: Both relays are manufactured by TE Connectivity Aerospace, Defense and Marine and are designated for aerospace, defense, and marine environments. Hermetic sealing and extended temperature range (-70°C to 125°C) support operation in demanding applications.
