Substitute Part Grouping Explanation
Substitution eligibility for the Phoenix Contact 1908790 is determined by strict alignment of the following critical parameters:
- Position Count & Pitch: 5 positions at 0.150" (3.81mm) spacing
- Physical Configuration: Male pins, shrouded (4 side), 90° right-angle orientation
- Mounting Method: Through-hole solder termination
- Electrical Performance: Current and voltage ratings sufficient for the application
- Compliance Standards: UL94 V-0 flammability rating and RoHS compliance
The TE Connectivity AMP Connectors part 1776135-5 meets these substitution criteria. This part maintains identical position count, pitch, shrouding configuration, and mounting orientation. Both components feature UL94 V-0 flammability ratings and RoHS compliance. The substitute part is classified as active, providing long-term availability for replacement and new designs.

Engineering Selection Recommendations
The TE Connectivity 1776135-5 is the qualified substitute for the obsolete Phoenix Contact 1908790. Selection of the substitute part is supported by the following factors:
- Product Status: The substitute part maintains active status, ensuring continued availability and supply chain stability.
- Compliance Alignment: Both parts meet UL94 V-0 flammability requirements and RoHS compliance standards.
- Electrical Sufficiency: The substitute part's 11A UL current rating exceeds the original 8A specification, providing margin for the intended application.
- Physical Compatibility: Identical pitch, position count, shrouding configuration, and mounting orientation ensure direct mechanical and electrical compatibility.
- Certification Consistency: Both components carry equivalent electrical certifications (300V UL rating) and material compliance documentation.
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 1776135-5 be used as a direct replacement for the Phoenix Contact 1908790?
A: Yes. Both parts share identical position count (5), pitch spacing (0.150"/3.81mm), shrouding configuration (4-side), header orientation (90° right-angle), and mounting method (through-hole solder). Electrical ratings and compliance certifications are equivalent or superior.
Q: What are the key differences between these two parts?
A: The substitute part features a higher UL current rating (11A versus 8A), operates across a specified temperature range (-40°C to 110°C), and uses phosphor bronze contact material. Housing material composition differs slightly (glass-filled nylon in the original versus standard nylon in the substitute). These differences do not affect substitution eligibility.
Q: Are there any packaging or inventory considerations?
A: The original part is supplied in standard packaging with 864 units in stock. The substitute part is available in bulk packaging with 966 units in stock. Packaging format should be verified against procurement requirements.
Q: Do both parts meet the same compliance standards?
A: Both parts are UL94 V-0 rated and RoHS compliant. The substitute part carries ROHS3 compliance, representing the current regulatory standard. Both parts are classified under the same HTSUS code (8536.69.4040) and ECCN (EAR99).
Q: What is the contact tail length difference, and does it matter?
A: The original part has a contact tail length of 0.134" (3.40mm), while the substitute has 0.122" (3.10mm). This 0.012" difference is within typical PCB design tolerances for through-hole solder termination and does not affect functional compatibility.
