Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1838277-3 is determined by the following critical parameters that must align with the original component specifications:

Mandatory Matching Parameters:

• Connector Type: Plug with Male Pins
• Number of Positions: 5
• Shell Size - Insert: M12-5
• Fastening Type: Threaded
• Mounting Type: Free Hanging (In-Line)
• Contact Finish - Mating: Gold
• Ingress Protection: IP67 or equivalent
• Current Rating: Equal to or greater than 5A
• Voltage Rating: Equal to or greater than 60VAC/DC
• Operating Temperature Range: Must encompass -25°C ~ 90°C
• RoHS Compliance: ROHS3 Compliant

Acceptable Variations:

• Termination Type: Solder Cup or Spring-Cage (both provide electrical connection capability)
• Orientation: Keyed or A-type (both provide polarization)
• Shell Material: Polyamide (PA) or equivalent plastic compounds
• Product Status: Active or Obsolete (both available for sourcing)

The Phoenix Contact 1424686 qualifies as a substitute based on these parameters, with the primary difference being termination method (Spring-Cage versus Solder Cup).

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The TE Connectivity 1838277-3 is classified as obsolete. The Phoenix Contact 1424686 is an active product with current manufacturing and availability. For new designs or system replacements, the active status of the Phoenix Contact substitute provides supply chain continuity and manufacturing support.

Compliance and Certification Alignment

Both components are ROHS3 Compliant and carry EAR99 ECCN classification. Both are subject to HTSUS code 8536.69.4020. The Phoenix Contact 1424686 includes UL94 V-0 flammability rating, providing additional material safety documentation.

Electrical Performance Parameters

The Phoenix Contact 1424686 operates at 4A current rating, which is lower than the original 5A specification. Applications requiring the full 5A capacity must account for this reduction. The voltage rating of 48VAC and 60VDC is compatible with the original 60VAC/DC specification for DC applications and lower AC voltage applications.

Operating Temperature Consideration

The original component operates from -25°C to 90°C. The substitute operates from -40°C to 85°C. The upper temperature limit of the substitute is 5°C lower than the original. Applications operating at temperatures above 85°C require evaluation against the original specification.

Termination Method Difference

The original uses solder cup termination; the substitute uses spring-cage termination. This represents a fundamental difference in wire connection methodology. Solder cup requires soldering; spring-cage requires wire insertion. System integration must accommodate this termination difference.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1424686 directly replace the TE Connectivity 1838277-3 in all applications?

A: The Phoenix Contact 1424686 is mechanically and electrically compatible for most applications. However, three factors require evaluation: (1) the current rating is 4A versus 5A on the original, (2) the maximum operating temperature is 85°C versus 90°C on the original, and (3) the termination method differs (spring-cage versus solder cup). Applications operating within 4A current, below 85°C temperature, and compatible with spring-cage termination can use this substitute.

Q: What is the difference between solder cup and spring-cage termination?

A: Solder cup termination requires wires to be inserted into a cup-shaped contact and soldered in place. Spring-cage termination uses a spring mechanism to grip and hold the wire without soldering. Both provide electrical connection; the choice depends on assembly process capability and application requirements.

Q: Are both connectors keyed to prevent incorrect mating?

A: The TE Connectivity 1838277-3 features keyed orientation. The Phoenix Contact 1424686 features A-type orientation. Both provide polarization to prevent incorrect mating, though the keying mechanism differs between the two designs.

Q: What is the ingress protection difference between IP65 and IP67?

A: The original component is rated IP67 (dust tight, waterproof). The substitute is rated IP65/IP67 (dust tight, water resistant, waterproof). IP67 provides complete protection against immersion; IP65 provides protection against water jets. The substitute meets or exceeds the original specification.

Q: Is the Phoenix Contact 1424686 available in the same packaging as the original?

A: The original TE Connectivity 1838277-3 packaging is not specified in the available data. The Phoenix Contact 1424686 is supplied in bulk packaging. Packaging configuration should be confirmed with the supplier for specific application requirements.

Q: Are both components RoHS compliant?

A: Yes, both the TE Connectivity 1838277-3 and Phoenix Contact 1424686 are ROHS3 Compliant. Both are suitable for applications requiring RoHS compliance.

Q: What is the shell size M12-5?

A: M12-5 indicates a circular connector with M12 metric thread diameter and 5 contact positions. This is a standard industrial connector size used in automotive and industrial applications.
