Phoenix Contact 1902822 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1902822 is a 3-position terminal block header with male pins, shrouded design, and 5.08mm pitch for vertical through-hole mounting. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The part operates at 12A (IEC) / 12A (UL) and 400V (IEC) / 300V (UL), with solder termination and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for terminal block headers is determined by strict alignment of electrical and mechanical parameters. The primary criteria are:

• Number of positions and positions per level (must match exactly: 3 positions, 1 level)
• Pitch specification (must match exactly: 5.08mm)
• Header type and pin configuration (must match: male pins, shrouded 4-side design)
• Termination style (must match: solder)
• Mounting type (must match: through hole, vertical orientation)
• Electrical ratings (current and voltage must meet or exceed application requirements)
• Flammability and compliance certifications (must maintain UL94 V-0 rating)

Phoenix Contact 1955866 meets all substitution criteria. It maintains identical position count, pitch, type, termination, and mounting specifications. The part is currently active in production, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1955866 is the direct active equivalent for obsolete part 1902822. Selection of 1955866 is supported by:

• Active product status ensuring current manufacturing and supply availability
• Identical functional specifications for position count, pitch, orientation, and termination
• Full compliance with UL94 V-0 flammability requirements
• Enhanced RoHS3 compliance over the original RoHS Compliant rating
• Improved moisture sensitivity level (MSL 1 vs. MSL 3), reducing handling and storage constraints
• IEC electrical ratings that match or exceed the original specification (12A IEC maintained)
• UL current rating of 10A meets applications requiring up to 10A per position; applications requiring 12A UL must reference the original 1902822 specification or confirm 10A sufficiency

Minor mechanical variations exist: contact tail length is shorter (2.60mm vs. 3.70mm) and insulation height is marginally reduced (12.00mm vs. 12.20mm). Housing material differs (LCP vs. polyamide), providing improved thermal and chemical resistance. These variations are within acceptable substitution parameters for standard terminal block applications.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1955866 directly replace 1902822 in existing designs?

A: Yes, for applications requiring up to 10A per position at UL ratings. The 3-position, 5.08mm pitch vertical through-hole configuration is identical. If the original design requires 12A at UL ratings, the 1902822 specification must be maintained or application requirements must be re-evaluated.

Q: What is the significance of the housing material change from polyamide to LCP?

A: Liquid Crystal Polymer (LCP) provides superior thermal stability and chemical resistance compared to polyamide. This material change is a design improvement and does not affect electrical or mechanical compatibility for standard applications.

Q: Does the shorter contact tail length (2.60mm vs. 3.70mm) affect PCB compatibility?

A: Contact tail length affects solder joint formation and mechanical support. PCB design must accommodate the 2.60mm tail length of 1955866. If the original design requires 3.70mm tail length, mechanical clearance and solder joint geometry must be re-evaluated.

Q: Why is the MSL rating improved from 3 to 1?

A: MSL 1 (Unlimited) indicates superior moisture resistance compared to MSL 3 (168 hours). This improvement reduces moisture-related failures during storage and handling, particularly in humid environments.

Q: Are there any compliance differences between the two parts?

A: Both parts maintain UL94 V-0 flammability rating. 1955866 carries ROHS3 Compliant status versus RoHS Compliant for 1902822, representing updated regulatory alignment. 1955866 also carries REACH Unaffected status, providing additional environmental compliance documentation.

Q: What is the inventory status for these parts?

A: 1902822 (obsolete) has 1107 pcs in stock. 1955866 (active) has 1066 pcs in stock. Active product status for 1955866 ensures continued availability through standard distribution channels.
