Phoenix Contact 1915259 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915259 is a 6-position terminal block header with male pins, shrouded on 4 sides, featuring 0.200" (5.08mm) pitch vertical through-hole mounting. This component is part of the COMBICON EMSTBV series and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from the active COMBICON product lines are necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915259 is determined by the following critical parameters:

• Position Count & Pitch: All substitute parts must maintain 6 positions at 0.200" (5.08mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Type & Orientation: Vertical through-hole male pin headers with 4-side shrouding are required to maintain form factor and mounting compatibility.
• Electrical Ratings: Substitute parts must meet or exceed the IEC and UL voltage and current specifications (minimum 320V IEC, 300V UL, 12A).
• Mounting & Termination: Through-hole mounting is mandatory. Termination style (press-fit vs. solder) represents a design change but does not prevent functional substitution.
• Compliance & Material: RoHS compliance and UL94 V-0 flammability rating are required for regulatory alignment.

The two identified substitutes (1777112 and 1792779) meet these core criteria while offering active product status and enhanced electrical ratings in specific configurations.

Parameter Comparison

Engineering Selection Recommendations

1777112 (COMBICON MSTBV Series)

Part 1777112 is the primary substitute for the obsolete 1915259. Both components share identical mechanical dimensions (6 positions, 5.08mm pitch, 0.472" insulation height, 0.154" contact tail length) and electrical current ratings (12A IEC/UL). The 1777112 offers enhanced voltage rating (630V IEC vs. 320V IEC) and maintains active product status with ROHS3 compliance. The primary design change is termination style: 1777112 uses solder termination instead of press-fit. This substitution is suitable for applications where PCB assembly processes support wave or reflow soldering.

1792779 (COMBICON CCV Series)

Part 1792779 serves as an alternative substitute with active product status and RoHS compliance. This part maintains the 6-position, 5.08mm pitch configuration and 0.472" insulation height. Key differences include reduced contact tail length (0.102" vs. 0.154"), lower UL current rating (10A vs. 12A), reduced IEC voltage rating (400V vs. 320V), black housing color, and LCP housing material instead of PBT. The 1792779 includes a locking ramp feature. This substitution is appropriate for applications with lower current requirements and where the shorter contact tail length accommodates PCB design constraints.

Both substitutes maintain compliance with UL94 V-0 flammability standards and unlimited moisture sensitivity levels. Selection between 1777112 and 1792779 depends on specific electrical requirements, PCB assembly capabilities, and mechanical space constraints.

Frequently Asked Questions (FAQ)

Q: Can 1777112 directly replace 1915259 on existing PCBs?

A: Mechanical compatibility is confirmed: both parts share identical pitch (5.08mm), position count (6), insulation height (0.472"), and contact tail length (0.154"). The primary consideration is termination method: 1915259 uses press-fit termination while 1777112 requires solder termination. PCB pad design and assembly process must support solder attachment.

Q: What is the voltage difference between 1915259 and 1777112?

A: The 1915259 is rated for 320V IEC, while 1777112 is rated for 630V IEC. Both meet the 300V UL requirement. The 1777112 provides higher voltage margin for applications operating near maximum ratings.

Q: Why does 1792779 have a shorter contact tail length?

A: The 1792779 contact tail length is 0.102" (2.60mm) compared to 0.154" (3.90mm) for the main part. This shorter tail accommodates different PCB thickness or assembly requirements. Verify PCB pad depth compatibility before substitution.

Q: Is 1792779 suitable for 12A applications?

A: The 1792779 is rated for 10A UL current, which is lower than the 12A rating of the main part. For applications requiring 12A operation, 1777112 is the appropriate substitute.

Q: Are all three parts RoHS compliant?

A: Yes. The 1915259 and 1792779 are RoHS Compliant. The 1777112 is ROHS3 Compliant, which represents an updated compliance standard. All three parts meet RoHS requirements.

Q: What is the difference between press-fit and solder termination?

A: Press-fit termination (1915259) uses mechanical insertion into PCB holes without solder. Solder termination (1777112, 1792779) requires thermal attachment during PCB assembly. Solder termination provides stronger mechanical and electrical connections for high-vibration or high-current applications.

Q: Can I use 1792779 in place of 1777112?

A: Mechanical compatibility exists (both 6-position, 5.08mm pitch, vertical through-hole). However, 1792779 has lower current rating (10A vs. 12A) and different contact tail length (0.102" vs. 0.154"). Substitution is valid only if application current requirements do not exceed 10A and PCB design accommodates the shorter tail length.
