Phoenix Contact 1915929 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915929 is a 21-position terminal block header with male pins, shrouded on four sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component is part of the COMBICON EMSTBVA series and carries an obsolete product status. Due to its obsolescence, identifying equivalent substitute parts from the active COMBICON product lines is essential for ongoing system maintenance, repairs, and new designs requiring compatible interconnection solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915929 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 21
• Pitch: 0.200" (5.08mm)
• Type: Header, Male Pins, Shrouded (4 Side)
• Header Orientation: Vertical
• Mounting Type: Through Hole
• Current - IEC: 12A
• Current - UL: 12 A
• Insulation Height: 0.472" (12.00mm)
• Material Flammability Rating: UL94 V-0

Allowable Variations:

• Termination Style: Press-Fit (original) may be substituted with Solder termination
• Housing Material: PBT (original) may be substituted with Polyamide (PA), Nylon, or Liquid Crystal Polymer (LCP)
• Contact Tail Length: May vary within mechanical compatibility constraints
• Voltage ratings: May exceed original specifications
• Product Status: Active products are preferred over obsolete

The two substitute parts listed below meet all mandatory matching criteria while offering improved availability and active product status.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1755927 (COMBICON MSTBVA Series)

Part 1755927 is the primary substitute for the obsolete 1915929. Both components share identical mechanical dimensions, position count, pitch, and electrical current ratings. The 1755927 features solder termination instead of press-fit, which is a standard substitution method in terminal block applications. The housing material differs (Polyamide/Nylon versus PBT), but both materials meet the UL94 V-0 flammability requirement. The 1755927 offers superior voltage rating (630 V IEC versus 320 V IEC) and carries active product status with ROHS3 compliance, making it suitable for new designs and ongoing production.

Phoenix Contact 1827964 (COMBICON CCVA Series)

Part 1827964 serves as an alternative substitute with active product status and RoHS compliance. This component maintains the same 21-position, 0.200" pitch configuration and 12A current rating. The primary distinction is the reduced contact tail length (0.102" versus 0.154"), which may require mechanical verification for PCB compatibility. The housing material is Liquid Crystal Polymer (LCP), which provides enhanced thermal and chemical resistance compared to PBT. The 1827964 is suitable for applications where the shorter contact tail and LCP material properties align with system requirements.

Selection Criteria:

• For direct mechanical and electrical replacement with minimal design modification: Select 1755927
• For applications requiring enhanced thermal performance or specific material properties: Select 1827964
• Verify PCB footprint compatibility, particularly contact tail length, before final selection
• Both substitutes provide improved product availability and compliance status compared to the obsolete 1915929

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1915929 be directly replaced with 1755927 or 1827964?

A: Both parts are functionally equivalent substitutes based on position count, pitch, connector type, and electrical ratings. However, the termination method differs (press-fit to solder), requiring PCB design verification. The 1827964 has a shorter contact tail (0.102" versus 0.154"), which may affect PCB hole placement compatibility.

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

A: The 1755927 maintains the original contact tail length (0.154") and uses Polyamide housing, while the 1827964 features a shorter contact tail (0.102") and Liquid Crystal Polymer housing. Both meet all mandatory electrical and mechanical parameters.

Q: Are there any compliance or regulatory differences between these parts?

A: The 1755927 carries ROHS3 compliance, while the 1827964 is RoHS compliant. Both maintain UL94 V-0 flammability ratings. The original 1915929 does not specify RoHS status. For applications requiring specific regulatory compliance, verify requirements against the substitute part certifications.

Q: Does the change from press-fit to solder termination affect compatibility?

A: Termination style change requires PCB design modification. Press-fit termination uses mechanical insertion, while solder termination requires through-hole soldering. The electrical and mechanical interface remains compatible; only the assembly process differs.

Q: What should be verified before selecting a substitute part?

A: Confirm PCB footprint compatibility, particularly contact tail length and hole diameter. Verify that the solder termination process is compatible with your assembly capabilities. Confirm that housing material properties (thermal, chemical resistance) meet application requirements. Validate voltage and current ratings against system specifications.

Q: Can both substitute parts be used interchangeably in the same application?

A: Both parts meet the mandatory electrical and mechanical parameters of the original 1915929. However, they differ in contact tail length and housing material. Select based on specific PCB design constraints and application requirements rather than interchangeably.
