Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1911127 is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: 13 positions at 0.138" (4.60mm) spacing
• Header Configuration: Male pins with four-sided shrouding
• Mounting Method: Vertical through-hole orientation
• Electrical Ratings: 8A current capacity and 250V (IEC) / 300V (UL) voltage withstand
• Material & Compliance: PBT housing with UL94 V-0 flammability rating and RoHS compliance

The Phoenix Contact 1843716 meets all these criteria. The primary difference is the termination style: the 1911127 uses press-fit termination, while the 1843716 employs solder termination. Both parts maintain identical electrical performance, mechanical dimensions (with minor contact tail length variation: 0.150" vs. 0.134"), and regulatory compliance. The 1843716 belongs to the COMBICON MCV series and carries active product status, making it the direct functional equivalent for applications where solder termination is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843716 is the direct functional equivalent for the obsolete 1911127. Both parts maintain identical electrical performance specifications, mechanical compatibility, and regulatory certifications. The 1843716 carries active product status, ensuring long-term availability and supply chain continuity.

The primary design consideration is termination method compatibility. The 1911127 uses press-fit termination, while the 1843716 requires solder attachment. PCB design modifications may be necessary if the original design was optimized for press-fit technology. The minor contact tail length difference (0.150" vs. 0.134") is within standard manufacturing tolerances and does not affect functional performance.

Both parts are RoHS compliant and carry UL94 V-0 flammability certification, meeting industrial safety and environmental standards. Selection should be based on manufacturing process capability and PCB layout requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1843716 directly replace the 1911127 without PCB modifications?

A: Mechanical and electrical compatibility is confirmed. However, termination method differs: the 1911127 uses press-fit termination while the 1843716 uses solder termination. PCB pad design and assembly process must accommodate solder attachment. Contact tail length variation (0.150" vs. 0.134") is within tolerance and does not require layout changes.

Q: Are there electrical performance differences between these parts?

A: No. Both parts maintain identical current ratings (8A IEC/UL), voltage ratings (250V IEC / 300V UL), and contact mating finish (tin). Electrical performance is equivalent.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 1843716 is actively manufactured and supported by Phoenix Contact, ensuring availability for new designs and replacement stock. The 1911127 is no longer produced, making the 1843716 the recommended alternative for ongoing applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1911127 and 1843716 are RoHS compliant with UL94 V-0 flammability ratings, meeting environmental and safety standards for industrial applications.

Q: Does the series designation (COMBICON EMCV vs. COMBICON MCV) affect compatibility?

A: Series designation reflects product line evolution. Both parts are Phoenix Contact COMBICON terminal block headers with identical functional specifications. The series difference does not impact electrical or mechanical compatibility.
