Phoenix Contact 1719138 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1719138 is a 3-position terminal block header with male pins, shrouded on all four sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component is part of the COMBICON MSTBVA series and is actively manufactured. Terminal block headers are essential interconnection components in industrial control systems, power distribution, and signal routing applications where reliable solder-terminated connections are required. Finding equivalent parts ensures design flexibility, supply chain continuity, and cost optimization while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1719138 is determined by strict alignment of the following critical parameters:

• Number of Positions and Pitch: Both must be 3 positions at 0.200" (5.08mm) spacing to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Type and Orientation: Vertical orientation with male pins and 4-side shrouding are mandatory for form-factor compatibility.
• Termination and Mounting: Solder termination with through-hole mounting ensures compatibility with standard PCB assembly processes.
• Electrical Ratings: Voltage and current ratings must meet or exceed the application requirements. The substitute part 796636-3 provides 15 A at 300 V (UL), which exceeds the main part's 12 A rating.
• Insulation Height and Contact Tail Length: These mechanical dimensions must be identical or functionally equivalent to ensure proper mating and PCB clearance.
• Compliance and Material Standards: RoHS compliance and UL94 V-0 flammability rating ensure regulatory and safety alignment.

The TE Connectivity AMP Connectors part 796636-3 meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1719138 and TE Connectivity 796636-3 are active products with full regulatory compliance. Selection between these parts should be based on the following engineering considerations:

Phoenix Contact 1719138: Select this part when the original design specification requires the exact contact tail length of 0.154" (3.90mm) or when Phoenix Contact supply chain preference is established. This part maintains the original design intent and is RoHS Compliant.

TE Connectivity 796636-3: Select this part as a substitute when supply availability of the Phoenix Contact part is constrained or when cost optimization is required. The substitute provides higher current capacity (15 A versus 12 A) and is ROHS3 Compliant. The contact tail length is 0.138" (4.60mm), which is 0.016" shorter. This difference must be evaluated against PCB solder pad depth and through-hole specifications to ensure adequate solder joint formation and mechanical stability.

Both parts are suitable for applications requiring UL94 V-0 flammability compliance and 300 V electrical isolation.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 796636-3 be used as a direct replacement for Phoenix Contact 1719138 in existing designs?

A: Yes, with one design consideration. The contact tail length differs by 0.016" (0.40mm). If the PCB design accommodates this variation in solder pad depth and through-hole specifications, the substitute is mechanically and electrically compatible. Both parts have identical pitch, position count, orientation, and voltage rating.

Q: What is the significance of the current rating difference (12 A versus 15 A)?

A: The TE Connectivity substitute provides higher current capacity. If the application requires only 12 A or less, both parts are suitable. The higher rating of the substitute does not create incompatibility; it provides additional design margin.

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

A: Both parts meet UL94 V-0 flammability requirements and are RoHS compliant. The Phoenix Contact part is RoHS Compliant, while the TE Connectivity part is ROHS3 Compliant. Both certifications satisfy current regulatory requirements for electronic components.

Q: How do the housing materials differ?

A: Phoenix Contact uses Polyamide (PA) Nylon, while TE Connectivity uses Polyamide (PA66) Nylon 6/6. Both are polyamide-based thermoplastics with equivalent mechanical and thermal properties for this application. The contact material also differs: Phoenix Contact does not specify contact material, while TE Connectivity specifies Copper Alloy.

Q: What packaging is available for both parts?

A: Both parts are supplied in Bulk packaging, suitable for high-volume manufacturing and assembly operations.

Q: Are operating temperature ranges specified for both parts?

A: Operating temperature is not specified for the Phoenix Contact 1719138. The TE Connectivity 796636-3 operates from -40°C to 110°C, which covers standard industrial and commercial temperature ranges.
