Parameter Comparison

Engineering Selection Recommendations

Primary Selection (1-1617019-4): The main part number 1-1617019-4 is the recommended selection for new designs and procurement. This part maintains Active product status with the highest current inventory level of 1100 pieces. All electrical and mechanical parameters are fully specified and verified.

Secondary Selection (2-1617019-0): Part number 2-1617019-0 (FW1105G00) is a parametric equivalent suitable for direct substitution. This part maintains Active product status with 981 pieces in inventory. All critical electrical and mechanical specifications are identical to the main part.

Tertiary Selection (FW1106G06): Part number FW1106G06 (M5757/10-043) is a parametric equivalent suitable for direct substitution. This part maintains Active product status with 736 pieces in inventory. All critical electrical and mechanical specifications are identical to the main part.

Alternative Selection (1-1617019-3): Part number 1-1617019-3 (FW1102G11) is a parametric equivalent with identical electrical and mechanical specifications. However, this part is listed as Discontinued at DiGi Electronics and should be considered only when other alternatives are unavailable. Current inventory is 1115 pieces.

All substitute parts share identical compliance status: RoHS non-compliant, REACH Unaffected, and MSL 1 (Unlimited). Selection among equivalent parts should be based on current inventory availability and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can 2-1617019-0 be used as a direct replacement for 1-1617019-4?

A: Yes. Part number 2-1617019-0 is a parametric equivalent with identical coil voltage (26.5VDC), contact form (DPDT 2 Form C), contact rating (3 A), coil current (39.3 mA), coil resistance (675 Ohms), operating temperature range (-65°C ~ 125°C), and all other critical electrical and mechanical specifications. Both parts feature chassis mount termination with solder hook connections and hermetically sealed construction.

Q: What is the difference between FW1106G06 and 1-1617019-4?

A: FW1106G06 and 1-1617019-4 are parametric equivalents with identical electrical and mechanical specifications. The primary difference is the manufacturer part number designation and internal design revision. Both parts maintain the same coil voltage, contact configuration, current rating, operating temperature range, and seal rating. FW1106G06 carries the military specification designation M5757/10-043.

Q: Why is 1-1617019-3 listed as discontinued?

A: Part number 1-1617019-3 is marked as Discontinued at DiGi Electronics, indicating it is no longer actively distributed through that channel. However, this part maintains identical electrical and mechanical specifications to the main part and remains available through existing inventory (1115 pieces). Selection of this part should be based on specific supply chain requirements and availability through alternative distribution channels.

Q: Are all substitute parts RoHS compliant?

A: No. All parts listed, including the main part 1-1617019-4 and all substitutes (2-1617019-0, FW1106G06, 1-1617019-3), are RoHS non-compliant. All parts maintain identical REACH Unaffected status and MSL 1 (Unlimited) rating.

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

A: Yes. All parts in this equivalency group are manufactured by TE Connectivity Aerospace, Defense and Marine and feature hermetically sealed construction with operating temperature range -65°C ~ 125°C. All parts share identical contact material composition (Silver and Gold) and coil specifications. Interchangeability is determined by the identical electrical and mechanical parameters across all listed parts.

Q: What is the significance of the 5 ms operate and release time?

A: The 5 ms operate time and 5 ms release time are critical switching performance specifications. All substitute parts maintain these identical timing parameters, ensuring equivalent response characteristics in switching applications. This specification applies uniformly across 1-1617019-4, 2-1617019-0, FW1106G06, and 1-1617019-3.

Q: How do the must operate and must release voltages affect substitution?

A: The must operate voltage (13.5 VDC) and must release voltage (1.47 VDC) define the minimum and maximum coil voltage thresholds for reliable relay operation. All substitute parts maintain identical thresholds, ensuring equivalent performance in circuits with the same voltage supply specifications. These parameters are critical for system design compatibility.
