Phoenix Contact 1915026 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915026 is an 18-position terminal block header with male pins, shrouded on four sides, featuring 0.197" (5.00mm) 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.

The part operates at 12A (IEC) / 12A (UL) and 320V (IEC) / 300V (UL), with press-fit termination and green polybutylene terephthalate (PBT) housing. RoHS compliance and UL94 V-0 flammability rating are standard specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915026 is determined by the following critical parameters:

• Position Count & Pitch: 18 positions at 0.197" (5.00mm) spacing (non-negotiable for mechanical fit)
• Header Type & Orientation: Male pins, shrouded (4 side), vertical through-hole configuration
• Electrical Ratings: Minimum 12A current and 320V voltage (IEC standard)
• Mounting Interface: Through-hole press-fit or solder termination
• Compliance: RoHS and UL94 V-0 flammability rating

Two substitute parts meet these criteria with documented compatibility:

1915026 → 1755668: Same position count, pitch, and shrouded male pin configuration. Differs in termination style (solder vs. press-fit) and housing material (polyamide vs. PBT). Voltage rating increased to 400V (IEC). Active product status.

1915026 → 1837187: Same position count, pitch, and shrouded male pin configuration. Differs in termination style (solder vs. press-fit), housing material (liquid crystal polymer vs. PBT), and color (black vs. green). Current rating increased to 16A (UL). Shorter contact tail length (0.079" vs. 0.154"). Active product status with defined operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

For Press-Fit Termination Requirement: The 1915026 uses press-fit termination. Both substitute parts (1755668 and 1837187) employ solder termination, requiring PCB design modification. If press-fit termination is mandatory, neither substitute is suitable without design revision.

For Active Product Status: Both 1755668 and 1837187 are active products with current manufacturing support, eliminating obsolescence risk. The 1915026 is obsolete and subject to availability constraints.

For Compliance Continuity: All three parts maintain UL94 V-0 flammability rating and RoHS compliance. Part 1755668 carries ROHS3 certification (enhanced compliance). Part 1837187 includes defined operating temperature range (-40°C ~ 100°C), providing thermal specification clarity absent in the main part.

For Electrical Performance: Part 1837187 offers increased UL current rating (16A vs. 12A), providing design margin. Part 1755668 increases IEC voltage rating to 400V. Both maintain minimum IEC 12A / 320V specifications of the original part.

For Mechanical Fit: Part 1837187 has reduced contact tail length (0.079" vs. 0.154"), which may affect PCB hole depth requirements and solder joint formation. Part 1755668 maintains identical contact tail length, minimizing mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can 1755668 directly replace 1915026 without PCB modification?

A: Mechanical and electrical compatibility exists for the 18-position, 5.00mm pitch configuration. However, termination style differs (solder vs. press-fit), requiring PCB design changes. Housing material differs (polyamide vs. PBT), which may affect thermal and chemical resistance characteristics. Verify PCB layout compatibility before implementation.

Q: What is the primary difference between 1755668 and 1837187?

A: Both are solder-termination alternatives to the press-fit 1915026. Part 1755668 maintains green color and 0.154" contact tail length, minimizing mechanical redesign. Part 1837187 offers higher UL current rating (16A), defined operating temperature range, and shorter contact tail (0.079"), requiring PCB hole depth verification. Housing materials differ (polyamide vs. liquid crystal polymer).

Q: Is the color difference between 1915026 (green) and 1837187 (black) functionally significant?

A: Color is a visual identifier only and does not affect electrical or mechanical function. Selection should be based on application requirements, PCB assembly standards, and visual identification protocols.

Q: Which substitute part requires the least PCB redesign?

A: Part 1755668 maintains identical contact tail length (0.154") and green color as the original 1915026. Only termination style changes from press-fit to solder, requiring standard PCB layout adjustment. Part 1837187 requires additional verification due to reduced contact tail length (0.079").

Q: Are both substitute parts suitable for new designs?

A: Yes. Both 1755668 and 1837187 are active products with current manufacturing support. Selection depends on termination preference (solder), housing material compatibility, and mechanical constraints. The original 1915026 is obsolete and not recommended for new designs.

Q: What compliance certifications apply to all three parts?

A: All parts maintain UL94 V-0 flammability rating and RoHS compliance. Part 1755668 carries enhanced ROHS3 certification. Verify specific compliance requirements for your application before final selection.
