Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 6-1877846-5 are identified based on the following core electrical and mechanical parameters that determine functional equivalency:

Primary Matching Criteria:

• Connector Type: Plug, Male Pins
• Number of Positions: 6
• Termination Method: Solder Cup
• Contact Finish: Gold
• Primary Material: Plastic/Thermoplastic
• Contact Material: Copper Alloy
• Mounting Type: Free Hanging (In-Line)

Substitution Logic: The EN3C6MX from Switchcraft Inc. qualifies as a substitute part because it maintains the same connector type, position count, termination method, and contact finish specifications. Both parts are designed for circular connector applications with solder cup termination and gold-plated contacts suitable for reliable electrical connections in medical and general-purpose instrumentation environments.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 6-1877846-5: Select this part when the application requires the full operating temperature range of -50°C to 170°C, particularly for medical device applications requiring extended high-temperature performance. This part maintains Active product status with established supply chain availability. RoHS Compliance certification is confirmed.

Switchcraft Inc. EN3C6MX: Select this part when the application operates within the -40°C to 65°C temperature range and requires higher current capacity (7.5A versus 6A). This substitute offers ROHS3 Compliance and includes integrated features such as backshell, cable clamp, and coupling nut. The EN3C6MX provides IP66/IP68 ingress protection rating, suitable for instrumentation and marine environments in addition to medical applications. REACH Unaffected status is confirmed.

Both parts maintain EAR99 export classification and identical HTSUS coding, supporting equivalent regulatory and compliance pathways. Selection between these parts depends on specific application temperature requirements, current demands, and environmental protection specifications.

Frequently Asked Questions (FAQ)

Q: Can the EN3C6MX directly replace the 6-1877846-5 in all applications?

A: Direct replacement depends on application-specific requirements. Both connectors share identical connector type, position count, termination method, and contact finish. However, the EN3C6MX operates at a maximum temperature of 65°C, while the 6-1877846-5 operates to 170°C. Applications requiring sustained operation above 65°C require the 6-1877846-5. The EN3C6MX provides higher current capacity (7.5A versus 6A) and integrated ingress protection (IP66/IP68).

Q: What are the key electrical differences between these parts?

A: The 6-1877846-5 is rated for 300VAC at 6A maximum current. The EN3C6MX is rated for 250VAC/DC at 7.5A maximum current. Applications requiring 300VAC operation must use the 6-1877846-5. Applications operating at 250VAC or lower with current demands up to 7.5A can utilize either part.

Q: Are both parts RoHS compliant?

A: Yes. The 6-1877846-5 is RoHS Compliant. The EN3C6MX is ROHS3 Compliant. Both meet RoHS requirements for restricted substance elimination.

Q: What is the difference in cable opening specifications?

A: The 6-1877846-5 accepts cable diameters of 0.157" to 0.205" (4.00mm to 5.20mm). The EN3C6MX accepts cable diameters of 0.160" to 0.265" (4.06mm to 6.73mm). The EN3C6MX provides a wider cable diameter range, accommodating larger gauge cables.

Q: Do both connectors have the same fastening mechanism?

A: No. The 6-1877846-5 uses Latch Lock fastening. The EN3C6MX uses Bayonet Lock fastening. These are different mechanical coupling methods and are not interchangeable in mated connector pairs.

Q: What is the moisture sensitivity level for both parts?

A: Both the 6-1877846-5 and EN3C6MX have Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts suitable for medical applications?

A: Yes. The 6-1877846-5 is specified for Medical applications as part of the Medical CPC series. The EN3C6MX lists Medical among its applications, along with General Purpose, Instrumentation, and Marine environments.

Q: What is the operating temperature difference between these connectors?

A: The 6-1877846-5 operates from -50°C to 170°C. The EN3C6MX operates from -40°C to 65°C. The 6-1877846-5 provides a significantly wider temperature range, particularly for high-temperature applications. The EN3C6MX provides lower temperature operation to -40°C compared to the 6-1877846-5 minimum of -50°C.
