Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899702 is determined by the following critical parameters:

Core Compatibility Parameters:

• Number of positions: 11
• Pitch: 0.200" (5.08mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Electrical ratings: IEC 12A/400V minimum; UL 15A/300V minimum
• Housing material flammability: UL94 V-0
• Contact mating finish: Tin

Variable Parameters (Allowed Differences):

• Termination style (Press-Fit vs. Solder)
• Housing material composition (PBT vs. LCP)
• Contact tail length
• Series designation
• Product status (Obsolete vs. Active)
• Color
• RoHS compliance version

The identified substitute parts 1776595 and 1792711 maintain all core compatibility parameters while differing in termination methodology and material specifications.

Parameter Comparison

Engineering Selection Recommendations

1776595 (COMBICON MSTB Series)

Part 1776595 is the primary substitute for the obsolete 1899702. Both components maintain identical electrical specifications (IEC 12A/400V, UL 15A/300V), identical pitch and position configuration, and equivalent mechanical form factor. The primary difference is termination methodology: 1776595 uses solder termination versus the press-fit design of 1899702. Both employ PBT housing material with UL94 V-0 flammability rating. Part 1776595 holds active product status and meets ROHS3 compliance, providing long-term availability and regulatory alignment. Contact tail length reduction (4.60mm vs. 4.19mm) requires PCB layout verification for through-hole depth compatibility.

1792711 (COMBICON CC Series)

Part 1792711 serves as an alternative substitute with active product status. This component maintains core electrical and mechanical compatibility with identical pitch, position count, and orientation. The UL current rating is reduced to 10A (versus 15A for 1899702), which may limit applicability in high-current circuits. Housing material differs (LCP vs. PBT), and color is black rather than green. Contact tail length is significantly shorter (2.60mm), requiring careful PCB design verification. This part is suitable for applications where the 10A UL rating is sufficient and where housing material and color differences are acceptable.

Product Status Consideration

Both substitute parts maintain active product status, ensuring continued availability and manufacturing support. The obsolete status of 1899702 necessitates transition to one of these alternatives for new designs or long-term system support.

Frequently Asked Questions (FAQ)

Q: Can 1776595 directly replace 1899702 in existing PCB designs?

A: Electrical and mechanical compatibility is confirmed for core functionality. However, the contact tail length differs (4.60mm vs. 4.19mm), requiring verification that PCB through-hole depth accommodates the shorter tail. Termination method change from press-fit to solder requires assembly process modification.

Q: What is the primary difference between 1776595 and 1792711?

A: Both are active substitutes with identical pitch and position configuration. Key differences include: 1776595 maintains the 15A UL current rating and PBT housing (matching 1899702 material), while 1792711 reduces UL current to 10A and uses LCP housing. Contact tail lengths differ significantly (4.60mm vs. 2.60mm). Selection depends on electrical requirements and PCB design constraints.

Q: Does the housing material change from PBT to LCP affect performance?

A: Both PBT and LCP materials meet UL94 V-0 flammability requirements and maintain identical electrical ratings. Material selection impacts thermal properties and mechanical characteristics. LCP (1792711) offers superior dimensional stability; PBT (1776595) provides cost efficiency. Selection should align with application thermal and mechanical requirements.

Q: Are there compatibility issues with the color difference between parts?

A: Color designation (green vs. black) is a visual identifier and does not affect electrical or mechanical function. Selection based on color is a design or assembly documentation preference, not a technical requirement.

Q: What assembly process changes are required when transitioning from 1899702 to 1776595?

A: The primary change is termination methodology: 1899702 uses press-fit termination, while 1776595 requires solder termination. This necessitates modification of assembly procedures and equipment. No changes to PCB layout are required beyond verification of through-hole depth compatibility with the shorter contact tail.

Q: Which substitute part is recommended for new designs?

A: Part 1776595 is the primary recommendation for new designs. It maintains the highest electrical rating (15A UL) and uses PBT housing material consistent with the original 1899702. Active product status ensures long-term availability and supply chain stability.
