Substitute Part Grouping Explanation

Substitution of the FCA-210-1008L is determined by electrical and mechanical parameter equivalence within the FCA-210 series. The substitute part must satisfy all of the following criteria:

Critical Substitution Parameters:

• Coil voltage: 6VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 10 A minimum
• Switching voltage capability: 115VAC, 28VDC maximum
• Coil current: 300 mA
• Coil type: Non Latching
• Mounting configuration: Chassis Mount
• Seal rating: Sealed - Hermetically
• Operating temperature range: -70°C ~ 125°C
• Contact material: Silver Cadmium Oxide (AgCdO)
• Coil resistance: 20 Ohms
• Termination style: PC Pin
• Integrated diode feature

The FCA-210 series designation confirms that substitute parts belong to the same relay family and share identical electrical performance characteristics and mechanical interfaces. Parts meeting these parameters are electrically and mechanically interchangeable without circuit modification or mechanical redesign.

Engineering Selection Recommendations

Both the FCA-210-1008L and FCA-210-0905M are active products manufactured by TE Connectivity Aerospace, Defense and Marine. Both parts are classified as RoHS non-compliant and share identical electrical specifications, mechanical interfaces, and environmental ratings.

Selection between these parts is based on supply chain availability and inventory status. The FCA-210-1008L maintains higher inventory levels (1048 units) compared to the FCA-210-0905M (879 units). Both parts carry identical ECCN (EAR99) and HTSUS classifications, ensuring equivalent regulatory treatment for export and procurement purposes.

The REACH status differs between the two parts: the FCA-210-1008L is REACH Unaffected, while the FCA-210-0905M is listed as Vendor Undefined. This distinction may influence procurement decisions in applications subject to REACH compliance requirements.

Frequently Asked Questions (FAQ)

Q: Are the FCA-210-1008L and FCA-210-0905M electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 6VDC coil voltage, DPDT contact configuration, 10A contact rating, 300mA coil current, 20 Ohm coil resistance, and identical switching voltage capabilities. They operate within the same temperature range (-70°C ~ 125°C) and feature identical timing characteristics (10ms operate and release times).

Q: Can these relays be used interchangeably in existing circuit designs?

A: Yes. Both parts feature identical PC Pin termination, chassis mount configuration, and hermetically sealed construction. No circuit modification or mechanical redesign is required for substitution.

Q: What is the difference between the FCA-210-1008L and FCA-210-0905M part numbers?

A: The part numbers reflect different internal configurations within the FCA-210 series. The suffix designations (1008L versus 0905M) indicate variations in internal relay construction. However, all electrical and mechanical parameters remain identical, ensuring full interchangeability.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are RoHS non-compliant and carry identical ECCN (EAR99) and HTSUS (8536.41.0050) classifications. The FCA-210-1008L is REACH Unaffected, while the FCA-210-0905M has Vendor Undefined REACH status. Applications subject to REACH compliance should verify the specific regulatory requirements with the component supplier.

Q: What is the MSL rating for these relays?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations during storage or handling.

Q: Can these relays operate at voltages below 6VDC?

A: Yes. Both relays must operate at a minimum of 4.5VDC and must release at 0.3VDC, providing operational flexibility within this voltage range.
