Phoenix Contact 1879418 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1879418 is a 15-position terminal block header with male pins, featuring a shrouded 4-side design and 0.150" (3.81mm) vertical pitch. This component is classified as obsolete and operates at 8A (IEC/UL) and 250V (IEC) / 300V (UL) ratings. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for ongoing system maintenance and new design implementations where this connector type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1879418 is determined by the following critical parameters:

• Position Count & Pitch: 15 positions at 0.150" (3.81mm) spacing
• Connector Type: Header with male pins, shrouded 4-side design
• Orientation & Mounting: Vertical through-hole configuration
• Electrical Ratings: 8A current capacity and 250V (IEC) / 300V (UL) voltage withstand
• Housing Material & Flammability: PBT with UL94 V-0 rating
• Contact Finish: Tin plating

The substitute part 1830729 maintains identical position count, pitch, connector type, orientation, mounting method, electrical ratings, housing material, flammability rating, and contact finish. The primary difference is the termination style (solder vs. press-fit) and minor variations in contact tail length and product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1830729 serves as a direct functional substitute for the obsolete 1879418 based on electrical equivalence and mechanical compatibility. Both components share identical position counts, pitch spacing, connector geometry, electrical ratings, and housing specifications.

The 1830729 is classified as active product status, ensuring ongoing availability and supply chain continuity. It carries ROHS3 compliance, representing current regulatory alignment. The primary design difference—solder termination versus press-fit—requires PCB layout verification to confirm compatibility with existing board designs. The contact tail length variance (0.138" vs. 0.150") must be evaluated against PCB hole depth and mounting requirements.

For applications where press-fit termination is mandatory, alternative solutions within the Phoenix Contact COMBICON series should be evaluated. For applications where solder termination is acceptable or preferred, the 1830729 provides full electrical and mechanical substitution with the advantage of active product status and current compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 1830729 directly replace the 1879418 on existing PCBs?

A: Mechanical compatibility depends on termination method acceptance. The 1879418 uses press-fit termination while the 1830729 uses solder termination. If the PCB is designed for press-fit connections, the 1830729 requires PCB redesign. If the PCB accommodates solder termination, direct substitution is feasible with verification of contact tail length against hole depth specifications.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components are rated at 8A (IEC/UL) and 250V (IEC) / 300V (UL). Voltage and current handling capacity are equivalent.

Q: What is the significance of the contact tail length difference?

A: The 1879418 has a contact tail length of 0.150" (3.81mm) while the 1830729 measures 0.138" (4.60mm). This 0.012" difference affects PCB hole engagement depth. Verify that the PCB hole depth accommodates the shorter tail length of the 1830729 to ensure proper mechanical retention and electrical contact.

Q: Why is the 1879418 obsolete while the 1830729 is active?

A: Product lifecycle management determines status. The 1830729 represents the current production equivalent within the Phoenix Contact COMBICON series. The 1879418 has been superseded in the manufacturer's product line.

Q: Are there compliance differences between the two parts?

A: Both are RoHS compliant. The 1830729 carries ROHS3 certification, representing alignment with current regulatory requirements. Both maintain UL94 V-0 flammability ratings and tin contact finish specifications.

Q: What packaging differences exist?

A: The 1879418 is listed with unspecified packaging, while the 1830729 is supplied in bulk packaging. Verify bulk packaging specifications against procurement requirements.
