Phoenix Contact 1911237 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1911237 is a 9-position terminal block header with male pins, shrouded on four sides, designed for 0.138" (4.60mm) pitch vertical through-hole mounting. This component belongs to the COMBICON EMC series and features press-fit termination with tin-plated mating contacts. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1911237 can be substituted with part number 1843295 based on the following critical parameters that remain constant across both components:

• Position Count & Pitch: Both parts feature 9 positions at 0.138" (4.60mm) pitch, ensuring mechanical and electrical compatibility with mating connectors
• Header Configuration: Both are male pin headers with 4-side shrouding, vertical orientation, and through-hole mounting
• Electrical Ratings: Both support 8A current (IEC and UL) and 300V (UL rating), meeting the same power delivery requirements
• Material & Compliance: Both use PBT housing with UL94 V-0 flammability rating and tin-plated mating contacts
• Moisture Sensitivity: Both are MSL 1 (Unlimited), indicating no moisture-related handling restrictions

The primary difference between these parts is the termination style: the 1911237 uses press-fit termination, while the 1843295 uses solder termination. Additionally, the 1843295 belongs to the COMBICON MCV series (active product status) and has slightly different mechanical dimensions (contact tail length and insulation height).

Parameter Comparison

Engineering Selection Recommendations

The 1843295 is the designated substitute for the obsolete 1911237 based on functional equivalence across all critical electrical and mechanical parameters. The 1843295 offers the advantage of active product status, ensuring continued availability and supply chain reliability. The COMBICON MCV series (1843295) provides ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements.

The primary consideration for substitution is the termination method change from press-fit to solder. This requires PCB design modification to accommodate solder pads instead of press-fit holes. The slight reduction in contact tail length (0.138" versus 0.150") and insulation height (0.362" versus 0.394") must be verified against PCB layout constraints to ensure proper clearance and alignment with mating connectors.

The IEC voltage rating increases from 160V to 250V in the substitute part, providing enhanced electrical performance margin without compromising any other specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1843295 directly replace the 1911237 on existing PCBs?

A: Direct PCB replacement is not possible without design modification. The 1911237 uses press-fit termination requiring plated through-holes, while the 1843295 requires solder pads. PCB layout must be redesigned to accommodate the solder termination style. Additionally, the reduced mechanical dimensions (contact tail length and insulation height) must be verified for compatibility with the mating connector and PCB clearances.

Q: Are the electrical ratings compatible between these parts?

A: Yes. Both parts support 8A current under IEC and UL standards. The UL voltage rating is identical at 300V. The IEC voltage rating of the 1843295 (250V) exceeds that of the 1911237 (160V), providing additional margin. Both parts are suitable for the same electrical applications within these ratings.

Q: What is the significance of the series change from COMBICON EMC to COMBICON MCV?

A: The series designation indicates different product families within Phoenix Contact's terminal block portfolio. The COMBICON MCV series (1843295) represents a current, actively manufactured product line, while the COMBICON EMC series (1911237) is obsolete. The functional compatibility is maintained through identical pitch, position count, and electrical specifications.

Q: Does the substitute part meet current regulatory compliance standards?

A: Yes. The 1843295 is ROHS3 compliant and REACH unaffected, meeting current European regulatory requirements. Both parts maintain UL94 V-0 flammability rating and identical moisture sensitivity classification (MSL 1).

Q: What are the packaging differences between these parts?

A: The 1911237 was supplied in standard packaging (not specified), while the 1843295 is supplied in bulk packaging. Inventory availability differs: 657 pieces for the 1911237 and 732 pieces for the 1843295.
