Phoenix Contact 1911266 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1911266 is a 12-position terminal block header with male pins, shrouded on four sides, designed for 0.138" (4.60mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

The primary driver for substitution is the obsolete product status combined with the availability of active alternatives that maintain electrical and mechanical compatibility within the COMBICON series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1911266 is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: 12 positions at 0.138" (4.60mm) spacing
• Connector Type & Orientation: Male pins, shrouded (4 side), vertical through-hole configuration
• Electrical Ratings: 8A current (IEC/UL), 250V (IEC), 300V (UL)
• Housing Material & Flammability: PBT with UL94 V-0 rating
• Contact Finish: Tin plating
• Mounting Interface: Through-hole PCB mounting with mating and mounting flange

The identified substitute part 1843321 maintains full equivalence across all critical electrical and mechanical parameters. The primary difference lies in termination style (solder vs. press-fit) and product status (active vs. obsolete), with no impact on functional compatibility in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843321 is a direct functional equivalent to the obsolete 1911266 for applications requiring 12-position, 4.60mm pitch terminal block headers with male pins and four-sided shrouding.

Product Status Consideration: The 1843321 maintains active product status within the Phoenix Contact COMBICON MCV series, ensuring ongoing availability and manufacturer support. The 1911266, classified as obsolete, presents supply chain risk for new procurements and long-term system maintenance.

Compliance & Certification: Both parts maintain equivalent electrical safety certifications (UL94 V-0 flammability rating, 8A/250V IEC and 8A/300V UL ratings). The 1843321 carries ROHS3 compliance, representing current regulatory alignment compared to the RoHS compliance designation of the 1911266.

Termination Methodology: The primary technical distinction is termination style—the 1911266 uses press-fit termination while the 1843321 employs solder termination. This difference requires PCB design accommodation but does not affect electrical performance or connector compatibility in equivalent circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can the 1843321 directly replace the 1911266 in existing PCB designs?

A: Functional replacement is possible with PCB design modification. The 1843321 requires solder termination instead of press-fit, necessitating through-hole pad design adjustment. All electrical and mechanical parameters remain equivalent.

Q: Are there differences in mating connector compatibility?

A: No. Both parts maintain identical 12-position, 4.60mm pitch male pin configuration with four-sided shrouding. Mating connectors designed for the 1911266 are fully compatible with the 1843321.

Q: What is the significance of the series designation change (EMCV to MCV)?

A: The series designation reflects product line evolution within Phoenix Contact's COMBICON terminal block family. The MCV series represents the current active product line, while EMCV is the legacy designation. Electrical and mechanical specifications remain equivalent.

Q: Does the ROHS3 compliance of the 1843321 affect compatibility?

A: No. ROHS3 compliance represents enhanced regulatory alignment and does not impact electrical or mechanical performance. The 1843321 is fully compatible with applications designed for RoHS-compliant components.

Q: What inventory considerations apply to these parts?

A: The 1911266 (obsolete) has 1089 pieces in stock. The 1843321 (active) has 1531 pieces available. For new designs and long-term system support, the 1843321 is the recommended selection due to active product status and superior supply chain availability.
