Phoenix Contact 1860744 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1860744 is a 12-position terminal block header with male pins, shrouded on four sides, designed for 0.150" (3.81mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of compatible substitutes essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

The primary function of this terminal block header is to provide a secure, standardized connection interface for wire termination in industrial control and power distribution applications. Its shrouded design offers enhanced electrical safety and mechanical protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1860744 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 12 positions at 0.150" (3.81mm) spacing
• Header Configuration: Male pins with four-side shrouding
• Mounting Method: Through-hole vertical orientation
• Electrical Ratings: 8A current capacity and 250V (IEC) / 300V (UL) voltage ratings
• Housing Material & Flammability: PBT with UL94 V-0 rating
• Contact Finish: Tin plating

The substitute part Phoenix Contact 1803523 meets all critical substitution criteria. The primary difference lies in the termination style (solder versus press-fit) and minor dimensional variations in contact tail length, which do not affect functional compatibility in standard applications.

Engineering Selection Recommendations

Phoenix Contact 1803523 is the qualified substitute for the obsolete 1860744 model. Selection rationale is based on the following factors:

• Product Status: The 1803523 maintains active production status, ensuring long-term availability and supply chain continuity, whereas the 1860744 is obsolete.
• Compliance Alignment: Both parts maintain equivalent electrical ratings (8A / 250V IEC, 8A / 300V UL) and identical material flammability certification (UL94 V-0).
• RoHS Compliance: The 1803523 meets ROHS3 compliance, representing current regulatory standards, while the 1860744 meets the earlier RoHS Compliant designation.
• Functional Equivalence: Identical position count, pitch, shrouding configuration, and mounting method ensure direct functional compatibility.
• Termination Consideration: The shift from press-fit to solder termination requires PCB design adjustment but does not affect electrical performance or safety ratings.

Frequently Asked Questions (FAQ)

Q: Can the 1803523 be used as a direct drop-in replacement for the 1860744?

A: Functional compatibility is confirmed for electrical and mechanical parameters. The primary consideration is termination method: the 1860744 uses press-fit termination while the 1803523 requires solder termination. PCB design must accommodate solder tail insertion and reflow processing.

Q: What is the significance of the contact tail length difference (0.150" vs. 0.134")?

A: The 0.016" (0.41mm) reduction in contact tail length on the 1803523 reflects design optimization in the COMBICON MCV series. This difference is within standard PCB through-hole tolerance ranges and does not affect electrical performance or mechanical retention.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts carry identical current ratings (8A) and voltage ratings (250V IEC / 300V UL). Material flammability certification (UL94 V-0) is also equivalent.

Q: Why is the 1860744 listed as obsolete?

A: The 1860744 belongs to the COMBICON EMCV series, which has been superseded by the COMBICON MCV series (represented by the 1803523). Phoenix Contact has transitioned production to the newer series, making the EMCV variant obsolete.

Q: Does the ROHS3 compliance of the 1803523 affect compatibility?

A: No. ROHS3 compliance represents an updated regulatory standard and is fully backward compatible. Systems designed for RoHS Compliant components can incorporate ROHS3 compliant substitutes without functional or safety impact.

Q: What packaging differences exist between these parts?

A: The 1860744 packaging is listed as unspecified, while the 1803523 is supplied in bulk packaging. This affects procurement and inventory management but does not alter component functionality.
