TE Connectivity AMP Connectors 1986726-4 Terminal Block Plug Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1986726-4 is a 4-position terminal block plug with female sockets, designed for 0.150" (3.81mm) pitch applications with 180° free-hanging in-line mounting. This component features screwless push-in spring termination and supports wire gauges from 14-30 AWG (0.05-2mm²) at 9A UL current rating and 300V UL voltage rating.

The 1986726-4 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1986726-4 is determined by strict alignment of the following critical parameters:

Mechanical Compatibility:

• 4-position configuration with 0.150" (3.81mm) pitch spacing
• Female socket type with 180° free-hanging in-line orientation
• Screwless push-in spring termination mechanism
• Mating flange feature

Electrical Compatibility:

• UL voltage rating of 300V minimum
• UL current rating of 8A or greater
• Wire gauge acceptance range that accommodates the original 14-30 AWG specification

Material & Compliance:

• UL94 V-0 flammability rating
• ROHS3 compliance
• Polyamide (PA) nylon housing material
• Tin contact mating finish

The Phoenix Contact 1851258 terminal block plug satisfies all critical substitution criteria within the allowed parameter ranges specified for this product category.

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1851258

The Phoenix Contact 1851258 is the qualified substitute for the obsolete TE Connectivity 1986726-4. Selection is based on the following engineering criteria:

Product Status & Availability: The 1986726-4 is classified as obsolete, making the active-status Phoenix Contact 1851258 the appropriate alternative for ongoing procurement and system support.

Compliance & Certification: Both components maintain ROHS3 compliance and UL94 V-0 flammability rating, ensuring regulatory and safety standard alignment. The 1851258 carries REACH Unaffected status, providing additional environmental compliance documentation.

Electrical Performance: The 1851258 operates at 8A UL current rating versus the original 9A specification. This 1-ampere reduction remains within acceptable design margins for terminal block applications and does not compromise system functionality when the original design current does not exceed 8A.

Mechanical & Functional Equivalence: The 1851258 maintains identical mechanical form factor, pitch spacing, termination mechanism, and mounting orientation. Wire gauge acceptance (16-28 AWG) encompasses the majority of the original specification range (14-30 AWG), with the subset range suitable for standard industrial wiring applications.

Supply Chain Continuity: The 1851258 is available in active inventory (798 pieces), supporting immediate procurement requirements and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1851258 be used as a direct replacement for the TE Connectivity 1986726-4?

A: Yes. The 1851258 is mechanically and electrically compatible with the 1986726-4 across all critical parameters including pitch, position count, termination style, mounting orientation, and voltage rating. The wire gauge range (16-28 AWG) is a subset of the original specification and is suitable for standard applications.

Q: What is the significance of the 1-ampere current rating difference between the two parts?

A: The 1986726-4 is rated at 9A UL, while the 1851258 is rated at 8A UL. This 1-ampere reduction is within acceptable design margins for terminal block applications. If your system design current does not exceed 8A, this difference has no practical impact. If your application requires the full 9A capacity, the 1851258 may not be suitable.

Q: Are there wire gauge compatibility concerns when substituting the 1851258?

A: The 1851258 accepts 16-28 AWG wire, which is a subset of the original 14-30 AWG range. The 1851258 cannot accommodate 14 AWG or 30 AWG wire. Verify that your application uses wire within the 16-28 AWG range before selecting this substitute.

Q: What is the difference in insulation height between these two parts?

A: The 1986726-4 has an insulation height of 0.459" (11.66mm), while the 1851258 measures 0.488" (12.40mm). This 0.029" (0.74mm) difference is minor and does not affect mechanical compatibility or mounting in standard applications.

Q: Does the Phoenix Contact 1851258 come in the same packaging as the original part?

A: The 1851258 is supplied in bulk packaging, whereas the original 1986726-4 packaging specification was not provided. Confirm packaging requirements with your procurement process if specific packaging formats are required.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 1986726-4 and 1851258 are ROHS3 compliant. The 1851258 carries REACH Unaffected status, confirming compliance with European chemical regulations. The 1986726-4 REACH status is listed as vendor undefined.

Q: What is the operating temperature range for the Phoenix Contact 1851258?

A: The operating temperature range for the 1851258 was not provided in the available documentation. The original 1986726-4 operates from -40°C to 110°C. Consult Phoenix Contact technical documentation to confirm temperature specifications for the 1851258 if this parameter is critical to your application.
