Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899634 terminal block header is determined by the following critical parameters:

Core Compatibility Parameters:

• Number of positions: 4
• Pitch: 0.200" (5.08mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Current rating (IEC): 12A minimum
• Voltage rating (IEC): 400 V minimum
• Material flammability rating: UL94 V-0

Allowable Variations:

• Termination style: Press-fit or solder acceptable
• Housing material: PBT or LCP acceptable
• Contact tail length: Variation permitted within mechanical envelope constraints
• Product status: Active status preferred for new applications
• Color: Variation permitted

The substitute parts 1776524 and 1792643 meet these core compatibility requirements while differing in termination methodology, housing material composition, and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

For Replacement Applications (Obsolete Part Substitution):

Part 1776524 is the primary substitute for the Phoenix Contact 1899634. Both components share identical electrical specifications (12A IEC, 400V IEC, 15A UL, 300V UL), matching pitch, position count, and shrouded male pin configuration. The transition from press-fit to solder termination requires PCB design modification but maintains electrical and mechanical compatibility. Part 1776524 holds active product status, ensuring long-term availability and supply chain continuity. RoHS3 compliance provides enhanced regulatory alignment for new designs.

Part 1792643 serves as a secondary substitute with equivalent IEC ratings (12A, 400V) but reduced UL current rating (10A versus 15A). The LCP housing material and shorter contact tail length (0.102" versus 0.165") introduce mechanical envelope differences requiring design verification. This part is suitable only when UL current requirements do not exceed 10A and mechanical constraints permit the reduced tail length. Active product status supports availability.

Compliance Considerations:

All three parts maintain UL94 V-0 flammability rating and RoHS compliance status. Part 1776524 achieves ROHS3 compliance, representing the most current regulatory standard. Selection should align with target application compliance requirements and supply chain qualification timelines.

Frequently Asked Questions (FAQ)

Q: Can part 1776524 directly replace the 1899634 in existing designs?

A: Electrical compatibility is confirmed across all IEC and UL ratings. The termination method change from press-fit to solder requires PCB redesign. Mechanical compatibility depends on PCB layout accommodation of the 0.138" (4.60mm) contact tail length versus the original 0.165" (4.19mm).

Q: What is the primary difference between 1776524 and 1792643?

A: Part 1776524 maintains the full 15A UL current rating and PBT housing material. Part 1792643 reduces UL current to 10A and uses LCP housing with a shorter 0.102" contact tail. Selection depends on application current requirements and mechanical space constraints.

Q: Are there packaging differences between these parts?

A: The 1899634 is supplied in standard packaging. Part 1776524 is available in bulk packaging. Part 1792643 is available in bulk packaging. Packaging format does not affect electrical or mechanical performance.

Q: Which substitute is recommended for new designs?

A: Part 1776524 is recommended for new designs. It provides active product status, ROHS3 compliance, and maintains full electrical specifications of the original part while offering improved supply chain availability.

Q: Does the housing material change affect performance?

A: Both PBT (parts 1899634 and 1776524) and LCP (part 1792643) materials maintain UL94 V-0 flammability rating and support the specified voltage and current ratings. Material selection does not impact electrical performance within the specified operating parameters.

Q: What mechanical considerations apply when switching from press-fit to solder termination?

A: Press-fit termination (1899634) requires precision PCB hole sizing and provides mechanical retention without solder. Solder termination (1776524, 1792643) requires standard PCB hole sizing and solder reflow processing. Both methods achieve equivalent electrical connection reliability when properly implemented.
