Phoenix Contact 1915136 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915136 is a 9-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 suitable substitute parts essential for ongoing production and maintenance applications. The part operates at 12A (IEC) / 12A (UL) and 230V (IEC) / 300V (UL), with press-fit termination and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915136 is determined by the following critical parameters:

• Position Count & Pitch: All substitute parts must maintain 9 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors.
• Header Type & Orientation: Vertical orientation with male pins and four-side shrouding is required for form-factor compatibility.
• Mounting Method: Through-hole mounting is mandatory for PCB integration.
• Electrical Ratings: Substitute parts must meet or exceed the IEC and UL voltage and current specifications (minimum 230V IEC / 300V UL and 12A).
• Compliance & Material Standards: RoHS compliance and UL94 V-0 flammability rating are required for regulatory conformance.

The two identified substitute parts (1776951 and 1837433) satisfy these core substitution criteria, though with variations in termination style, voltage rating, and housing material that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776951 is an active-status substitute offering identical mechanical form-factor and electrical performance to the 1915136. The primary difference is termination style: 1776951 uses solder termination versus the original press-fit method. This part provides higher IEC voltage rating (400V vs. 230V) and maintains PBT housing material. RoHS compliance and UL94 V-0 certification are retained. Selection of 1776951 is appropriate where solder termination is compatible with PCB assembly processes.

Phoenix Contact 1837433 is an active-status substitute with identical mechanical compatibility and electrical ratings meeting or exceeding the original specification (16A UL vs. 12A original). This part differs in housing material (Liquid Crystal Polymer vs. PBT), color (black vs. green), and contact tail length (0.079" vs. 0.154"). The 1837433 provides enhanced thermal performance and higher current capacity. RoHS compliance and UL94 V-0 certification are maintained. Selection of 1837433 is appropriate where enhanced thermal characteristics and higher current capacity are beneficial, provided color and contact geometry are compatible with the application.

Both substitute parts carry active product status, ensuring ongoing availability and supply chain stability compared to the obsolete 1915136.

Frequently Asked Questions (FAQ)

Q: Can 1776951 directly replace 1915136 in existing designs? A: Mechanical and electrical compatibility is maintained. The primary consideration is termination method: 1776951 requires solder attachment to PCB pads, whereas 1915136 uses press-fit termination. PCB pad design must accommodate solder termination. Electrical ratings of 1776951 exceed the original specification.

Q: What is the key difference between 1776951 and 1837433? A: Both are mechanically compatible 9-position, 5.00mm pitch headers. 1776951 retains PBT housing material identical to the original; 1837433 uses Liquid Crystal Polymer housing. 1837433 provides higher UL current rating (16A vs. 12A) and operates across -40°C to 100°C temperature range. Contact tail length differs (0.079" vs. 0.154"), affecting PCB pad spacing requirements.

Q: Are both substitute parts RoHS compliant? A: Yes. Both 1776951 and 1837433 are RoHS compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements equivalent to the original 1915136.

Q: Which substitute should be selected for new production? A: Selection depends on termination process capability and thermal/current requirements. For solder-based assembly with standard current requirements, 1776951 is appropriate. For applications requiring enhanced thermal performance or higher current capacity, 1837433 is suitable. Both are active-status parts with assured supply availability.

Q: Does contact tail length difference affect compatibility? A: Yes. 1837433 has shorter contact tail length (0.079" vs. 0.154"), which affects PCB pad hole depth and spacing. PCB design must be verified for compatibility with the selected substitute part's contact geometry.
