Phoenix Contact 1908787 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1908787 is a 4-position terminal block header with male pins, shrouded design, and 0.150" (3.81mm) pitch in 90° right-angle through-hole configuration. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part operates at 8A (IEC) / 8A (UL) and 250V (IEC) / 300V (UL), with UL94 V-0 flammability rating and RoHS compliance.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

Electrical Compatibility: Current and voltage ratings must meet or exceed the original specification (8A UL / 300V UL minimum)
Physical Compatibility: 4-position count, 0.150" (3.81mm) pitch, 90° right-angle orientation, through-hole mounting, and solder termination
Connector Type: Male pins with 4-side shrouded design
Regulatory Compliance: UL94 V-0 flammability rating and RoHS compliance status
Contact Finish: Tin plating for mating surfaces

All four substitute parts meet these core criteria. Variations in housing material, contact material, and operating temperature ranges do not affect functional substitution within the specified electrical and mechanical envelope.

Engineering Selection Recommendations

Primary Recommendation: Phoenix Contact 1803293

The 1803293 is the direct equivalent from the original manufacturer. It maintains identical electrical specifications (8A UL / 300V UL), physical dimensions, and connector configuration. As an active product with ROHS3 compliance and 4,281 units in stock, it provides the highest design continuity and supply reliability. The only difference is housing material (PBT vs. polyamide) and color (green vs. black), neither of which affects electrical or mechanical function.

Secondary Recommendations: TE Connectivity 1776135-4 and Amphenol Anytek OQ0432510000G

Both parts exceed the original current rating (11A and 10A respectively) while maintaining 300V voltage specification and UL94 V-0 compliance. These cross-manufacturer alternatives provide additional supply sources and are suitable for direct substitution in applications where the original specification is met or exceeded.

Tertiary Option: On Shore Technology OSTOQ043251

This part meets the core mechanical and electrical envelope but lacks specified flammability rating and current rating data. Use only when primary and secondary options are unavailable, and verify compliance requirements with the manufacturer.

Frequently Asked Questions (FAQ)

Q: Can I substitute the obsolete 1908787 with the 1803293?

A: Yes. The 1803293 is functionally equivalent with identical electrical ratings (8A UL / 300V UL), pitch (0.150"), position count (4), orientation (90° right-angle), and connector type (male pins, shrouded). Both are RoHS compliant and UL94 V-0 rated. Housing material and color differences do not affect performance.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution requires matching: 4-position count, 0.150" (3.81mm) pitch, 90° right-angle orientation, through-hole mounting, solder termination, male pins with 4-side shrouding, minimum 8A current rating, 300V voltage rating, UL94 V-0 flammability, and tin contact finish.

Q: Can I use the TE Connectivity 1776135-4 as a substitute?

A: Yes. The 1776135-4 meets all core substitution criteria with higher current capacity (11A vs. 8A), identical voltage rating (300V), and UL94 V-0 compliance. Operating temperature range (-40°C to 110°C) and phosphor bronze contact material do not affect compatibility.

Q: What is the difference between the Phoenix Contact 1908787 and 1803293?

A: The primary differences are product status (obsolete vs. active), housing material (polyamide vs. PBT), color (black vs. green), and RoHS certification level (RoHS vs. ROHS3). Electrical and mechanical specifications are identical.

Q: Are all substitute parts available in the same packaging?

A: All substitute parts are available in bulk packaging. The original 1908787 packaging specification was not provided. Confirm packaging requirements with your procurement team.

Q: Which substitute offers the best supply availability?

A: Phoenix Contact 1803293 has the highest inventory (4,281 units), followed by On Shore Technology OSTOQ043251 (1,572 units), Amphenol Anytek OQ0432510000G (1,007 units), and TE Connectivity 1776135-4 (703 units).
