Phoenix Contact 1915770 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915770 is a 22-position terminal block header with male pins, featuring a 4-side shrouded design and 0.197" (5.00mm) pitch for vertical through-hole mounting. This component is classified as obsolete, making identification of suitable substitute parts 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 UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915770 is determined by the following critical parameters:

• Position Count & Pitch: All substitute parts must maintain 22 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with existing mating connectors and PCB layouts.
• Header Type & Orientation: Vertical through-hole male pin headers with 4-side shrouding are required to match the original form factor and mounting interface.
• Electrical Ratings: Substitute parts must meet or exceed the IEC and UL current and voltage specifications (minimum 12A / 320V IEC, 12A / 300V UL) to maintain system safety margins.
• Flammability Compliance: UL94 V-0 rating is mandatory for applications requiring flame-retardant materials.
• Termination Compatibility: While the original part uses press-fit termination, solder-terminated alternatives are acceptable substitutes provided they maintain the same contact tail geometry and insulation height for proper mating.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1755707 is the primary substitute for the obsolete 1915770. Both parts share identical position count, pitch, header type, orientation, and contact tail geometry. The 1755707 is currently in active production status with higher inventory availability (1045 pcs vs. 726 pcs). The transition from press-fit to solder termination requires PCB design modification but maintains full electrical compatibility. The 1755707 exceeds the original voltage specification (400V IEC vs. 320V IEC) and carries ROHS3 compliance with MSL 1 rating, making it suitable for modern manufacturing environments.

Phoenix Contact 1837226 serves as a secondary substitute with active product status and higher UL current rating (16A vs. 12A). However, the contact tail length differs significantly (0.079" vs. 0.154"), which may affect mating depth and connector engagement. The housing material change from PBT to LCP and color change from green to black represent material upgrades with improved thermal and mechanical properties. The operating temperature range (-40°C to 100°C) is specified for this part, whereas the original part does not provide this parameter. Selection of the 1837226 requires mechanical validation of the reduced contact tail length against existing mating connectors.

Frequently Asked Questions (FAQ)

Q: Can the 1755707 directly replace the 1915770 without PCB modifications?

A: The 1755707 maintains identical mechanical dimensions (22 positions, 5.00mm pitch, 0.154" contact tail, 0.472" insulation height) and electrical ratings, ensuring connector compatibility. However, the termination method changes from press-fit to solder, requiring PCB pad redesign and assembly process modification.

Q: What is the impact of the 1837226's shorter contact tail (0.079" vs. 0.154")?

A: The reduced contact tail length affects mating depth with the connector receptacle. Existing mating connectors designed for the 0.154" tail may not achieve proper engagement or retention with the 0.079" tail. Mechanical validation against the specific mating connector is required before implementation.

Q: Are both substitute parts RoHS compliant?

A: The 1755707 carries ROHS3 compliance with MSL 1 rating. The 1837226 does not specify RoHS status in the provided data. Compliance verification should be confirmed with the manufacturer for specific application requirements.

Q: Does the housing material change affect electrical performance?

A: The housing material transitions from PBT (1915770) to PA/Nylon (1755707) or LCP (1837226) do not alter the electrical ratings or flammability classification (all maintain UL94 V-0). Material selection impacts mechanical durability, thermal stability, and chemical resistance rather than electrical function.

Q: Which substitute is recommended for new designs?

A: The 1755707 is recommended for new designs due to active production status, higher inventory availability, ROHS3 compliance, and identical contact geometry to the original part. The 1837226 should be considered only when the higher UL current rating (16A) is required and mechanical compatibility with the shorter contact tail is confirmed.
