• Termination method: Solder cup
• Contact material and finish: Copper alloy with gold plating
• Mounting configuration: Free Hanging (In-Line)
• Primary shell material: Thermoplastic
• Moisture sensitivity level: MSL 1 (Unlimited)
• ECCN classification: EAR99
• HTSUS code: 8536.69.4020

Electrical Compatibility: Both parts support solder cup termination and maintain copper alloy contacts with gold finish, ensuring equivalent electrical performance in circuit applications. Current and voltage ratings differ between parts; selection depends on specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

6-1877846-9 (TE Connectivity AMP Connectors) is the primary specification for applications requiring the Medical CPC series designation. This part maintains RoHS Compliance status and operates across an extended temperature range of -50°C to 170°C, supporting high-temperature medical device applications. The latch lock fastening mechanism and PPS insert material provide mechanical stability in medical environments.

EN3C6MX (Switchcraft Inc.) serves as an equivalent substitute when the following conditions are met:

• Application environment permits operating temperatures within -40°C to 65°C range
• Circuit voltage requirements do not exceed 250VAC/DC
• Circuit current requirements do not exceed 7.5A
• Bayonet lock fastening mechanism is acceptable for the application
• IP66/IP68 ingress protection rating provides added environmental sealing benefit
• Cable opening dimensions accommodate 0.160" to 0.265" (4.06mm to 6.73mm) cable sizes
• ROHS3 Compliance status meets regulatory requirements

Both parts maintain identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications, ensuring equivalent export and tariff treatment. MSL 1 rating indicates unlimited shelf life for both components.

Frequently Asked Questions (FAQ)

Q: Can EN3C6MX replace 6-1877846-9 in all medical applications?

A: EN3C6MX substitution is limited to applications where operating temperature remains within -40°C to 65°C. The 6-1877846-9 supports extended temperature operation to 170°C, required for certain medical sterilization and high-temperature processing applications. Verify application temperature requirements before substitution.

Q: What is the difference in fastening mechanisms between these connectors?

A: The 6-1877846-9 uses a latch lock fastening type, while EN3C6MX employs a bayonet lock mechanism. Both are free-hanging in-line configurations. Mechanical compatibility with mating connectors must be verified based on the specific receptacle design in the application.

Q: Are the cable opening dimensions compatible?

A: No. The 6-1877846-9 accepts cables with 0.106" to 0.154" (2.70mm to 3.90mm) diameter, while EN3C6MX accommodates 0.160" to 0.265" (4.06mm to 6.73mm) diameter cables. Cable size must match the selected connector specification.

Q: What is the significance of the insert material difference?

A: The 6-1877846-9 uses Polyphenylene Sulfide (PPS) insert material, while EN3C6MX uses elastomer. PPS provides superior chemical resistance and higher temperature stability, making it suitable for extended temperature medical applications. Elastomer inserts offer flexibility and environmental sealing benefits.

Q: Do both connectors meet current regulatory compliance standards?

A: Yes. The 6-1877846-9 maintains RoHS Compliance status, and EN3C6MX meets ROHS3 Compliance requirements. Both parts are classified as EAR99 for export purposes and share identical HTSUS tariff classification (8536.69.4020).

Q: What is the current rating difference and when does it matter?

A: The 6-1877846-9 is rated for 6A maximum current, while EN3C6MX supports 7.5A. For circuits requiring current above 6A but within 7.5A limits, EN3C6MX provides additional capacity. For circuits at or below 6A, both parts are equivalent.

Q: How do voltage ratings compare between these parts?

A: The 6-1877846-9 is rated for 300VAC, while EN3C6MX supports 250VAC/DC. The 6-1877846-9 provides higher AC voltage capability. For applications requiring 250VAC or less, both parts are suitable. For applications exceeding 250VAC, the 6-1877846-9 is required.

Q: What does IP66/IP68 ingress protection on EN3C6MX provide?

A: IP66/IP68 rating indicates dust-tight and water-resistant/waterproof performance. The 6-1877846-9 does not specify ingress protection rating. EN3C6MX offers enhanced environmental sealing for applications exposed to moisture or particulate contamination.
