Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 1781124 are identified based on strict parameter alignment in the following critical areas:

Electrical Compatibility: All substitute parts must maintain equivalent current and voltage ratings within the allowed operational envelope. The main part specifies 12A IEC / 15A UL and 630V IEC / 300V UL. Substitutes are evaluated against these specifications.

Mechanical Compatibility: Substitutes must match the 16-position configuration, 0.200" (5.08mm) pitch, 180° wire entry orientation, and free-hanging in-line mounting type. Screw termination style and M3 screw size are required parameters.

Wire Gauge Acceptance: The main part accepts 12-30 AWG (0.2-2.5mm²). Substitutes with overlapping wire gauge ranges are considered compatible within their specified limits.

Regulatory Compliance: All parts must maintain UL94 V-0 flammability rating and ROHS3 compliance status.

Identified Substitutes:

• TJ1651560000G (Amphenol Anytek, 01-508 Series)
• TJ1671560000G (Amphenol Anytek, 01-500 Series)

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1781124: Primary selection for applications requiring 15A UL current rating and extended wire gauge acceptance (12-30 AWG). Supports 630V IEC specification. Active product status with full ROHS3 compliance and UL94 V-0 flammability rating.

Amphenol Anytek TJ1651560000G: Direct pitch-matched substitute (0.200" / 5.08mm). Rated for 12A UL current. Wire gauge limited to 12-24 AWG (1-2.5mm²). Active product status with equivalent compliance certifications. Operating temperature range specified as -40°C to 115°C.

Amphenol Anytek TJ1671560000G: Pitch variant at 0.197" (5.00mm). Rated for 12A UL current. Wire gauge limited to 12-24 AWG (1-2.5mm²). Active product status with equivalent compliance certifications. Operating temperature range specified as -40°C to 115°C. Mechanical compatibility requires pitch tolerance verification in target application.

Selection between these parts depends on current requirement (15A vs. 12A), wire gauge range needed, and pitch specification tolerance in the application circuit.

Frequently Asked Questions (FAQ)

Q: Can TJ1651560000G directly replace Phoenix Contact 1781124?

A: TJ1651560000G matches the 0.200" (5.08mm) pitch specification. Both parts are 16-position plugs with 180° wire entry and free-hanging mounting. The primary difference is current rating: TJ1651560000G is rated 12A UL versus 1781124 at 15A UL. Wire gauge acceptance differs: TJ1651560000G accepts 12-24 AWG versus 1781124 at 12-30 AWG. Substitution is valid when application current does not exceed 12A and wire gauges remain within 12-24 AWG range.

Q: What is the pitch difference between TJ1671560000G and the main part?

A: TJ1671560000G operates at 0.197" (5.00mm) pitch versus the main part at 0.200" (5.08mm). This 0.03mm difference affects mechanical fit in mating connectors and PCB layouts. Substitution requires confirmation that the receiving connector or header accepts 5.00mm pitch spacing.

Q: Are all three parts ROHS3 compliant?

A: Yes. Phoenix Contact 1781124, Amphenol Anytek TJ1651560000G, and Amphenol Anytek TJ1671560000G all carry ROHS3 Compliant status. All three maintain UL94 V-0 flammability rating and are classified as Active products.

Q: What wire gauge range applies when substituting?

A: The main part accepts 12-30 AWG (0.2-2.5mm²). Both Amphenol Anytek substitutes accept 12-24 AWG (1-2.5mm²). When substituting, wire gauge must fall within the 12-24 AWG range to remain compatible with both the substitute part and the original specification overlap.

Q: Does screw torque differ between parts?

A: Main part specifies 0.5-0.6 Nm (4.4-5.3 Lb-In). TJ1651560000G and TJ1671560000G specify 0.56 Nm (5.0 Lb-In). Both fall within acceptable M3 screw termination parameters for this connector class.

Q: What is the operating temperature range for substitutes?

A: Amphenol Anytek TJ1651560000G and TJ1671560000G both specify -40°C to 115°C operating temperature. Phoenix Contact 1781124 does not specify operating temperature in the provided parameters.
