Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1911156 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 16
• Pitch: 0.138" (4.60mm)
• Header type: Male pins, shrouded (4 side)
• Header orientation: Vertical
• Mounting type: Through hole
• Current rating: 8A (IEC/UL)
• Voltage rating: 250V (IEC) / 300V (UL)
• Housing material: Polybutylene Terephthalate (PBT)
• Material flammability rating: UL94 V-0

Allowable Variations:

• Termination style: Press-fit or solder
• Series designation: COMBICON EMCV or COMBICON MCV
• Product status: Active or obsolete
• Contact tail length: Minor dimensional variations within mechanical tolerance
• Compliance certifications: RoHS or ROHS3

The Phoenix Contact 1843745 qualifies as a direct substitute based on these criteria. Both parts maintain identical electrical specifications, mechanical footprint, and functional performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843745 is the qualified substitute for the obsolete 1911156 model. Both components maintain identical electrical performance specifications (8A at 250V IEC / 300V UL) and mechanical compatibility for 16-position, 4.60mm pitch vertical through-hole applications.

Key Selection Factors:

The primary difference between these parts is termination style: the 1911156 uses press-fit termination, while the 1843745 employs solder termination. This distinction affects assembly methodology but does not impact electrical or mechanical performance within the specified operating parameters.

The 1843745 carries active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment with current environmental standards. The 1911156, classified as obsolete, presents supply chain risk for new designs and ongoing production requirements.

Contact tail length varies by 0.016" (0.41mm) between the two parts, remaining within standard mechanical tolerances for through-hole PCB mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the 1843745 directly replace the 1911156 in existing assemblies?

A: Yes. Both parts share identical electrical ratings (8A, 250V IEC / 300V UL), mechanical footprint (16 positions, 4.60mm pitch), and physical dimensions (0.362" insulation height). The contact tail length difference of 0.016" is within standard PCB hole tolerance specifications.

Q: What is the primary difference between these two parts?

A: Termination style differs: the 1911156 uses press-fit termination for automated assembly, while the 1843745 uses solder termination for manual or wave soldering processes. Both methods achieve equivalent electrical and mechanical connections.

Q: Why is the 1911156 classified as obsolete?

A: Product obsolescence reflects Phoenix Contact's lifecycle management. The 1843745 represents the current active equivalent within the COMBICON terminal block family, offering the same functional performance with improved supply chain availability.

Q: Are there compliance differences between these parts?

A: Both parts meet UL94 V-0 flammability requirements and RoHS environmental standards. The 1843745 carries ROHS3 certification, representing the latest compliance designation. Both are suitable for regulated industrial applications.

Q: Does the contact tail length difference affect PCB design?

A: No. The 0.016" (0.41mm) variation falls within standard PCB through-hole tolerance ranges (typically ±0.010" to ±0.015"). No PCB redesign is required for substitution.

Q: What packaging is available for the 1843745?

A: The 1843745 is supplied in bulk packaging, differing from the 1911156 standard packaging designation. Confirm packaging requirements with your procurement specifications.
