Frequently Asked Questions (FAQ)

Q: Can the substitute parts be used interchangeably with the B07D111BC4-0202 in existing circuit designs?

A: Yes. All substitute parts maintain identical electrical specifications including coil voltage (26.5VDC), contact form (DPDT), contact rating (10 A), switching voltage (115VAC, 28VDC - Nom), coil current (88.3 mA), and timing parameters (10 ms operate and release times). Mechanical compatibility is also maintained through identical mounting type (Chassis Mount), termination style (PC Pin), and seal rating (Sealed - Hermetically).

Q: Are there any differences in contact material between the main part and substitutes?

A: No. All parts, including the main part B07D111BC4-0202 and all substitutes (1-1617003-0, 1-1617004-6, B07B311BC3), use Silver Cadmium Oxide (AgCdO) contact material. This ensures consistent switching performance and reliability across all equivalent parts.

Q: What is the operating temperature range for these relays?

A: All parts operate across the identical temperature range of -65°C to 125°C. This wide operating range supports aerospace, defense, and marine applications requiring performance in extreme environmental conditions.

Q: Do all substitute parts have the same coil resistance?

A: Yes. The B07D111BC4-0202 and all substitute parts (1-1617003-0, 1-1617004-6, B07B311BC3) have a coil resistance of 300 Ohms. This parameter is critical for circuit design and remains constant across all equivalent parts.

Q: What are the must-operate and must-release voltage specifications?

A: All parts maintain identical voltage thresholds: must operate at 13 VDC minimum and must release at 1.8 VDC maximum. These specifications ensure predictable relay behavior across the full range of coil voltage conditions.

Q: Are there any RoHS or environmental compliance differences between the parts?

A: No. All parts maintain identical compliance status: RoHS non-compliant and REACH Unaffected. The Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the difference in ECCN classification between the parts?

A: The B07D111BC4-0202 and 1-1617003-0 are classified as EAR99, while 1-1617004-6 is classified as 7A994. The B07B311BC3 is classified as EAR99. ECCN classification affects export control requirements and should be verified for applications involving international shipment or end-use considerations.
