Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899618 is determined by the following critical parameters:

Core Compatibility Parameters:

• Number of positions: 2
• Pitch spacing: 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 10A/300V minimum
• Material flammability: UL94 V-0
• Contact mating finish: Tin

Allowed Variations:

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

Two substitute parts meet these criteria: Phoenix Contact 1776508 and Phoenix Contact 1792627.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776508 (COMBICON MSTB Series)

This substitute is the primary equivalent for the 1899618. Both parts maintain identical electrical specifications (IEC 12A/400V, UL 15A/300V), pitch spacing, orientation, and shrouded male pin configuration. The 1776508 is active in production, ensuring long-term availability. The primary difference is termination style: the 1776508 uses solder termination versus the press-fit design of the original. Housing material remains PBT with UL94 V-0 rating. Contact tail length is shorter (0.138" vs. 0.165"), which may require PCB layout verification for through-hole depth compatibility. RoHS3 compliance provides enhanced regulatory alignment compared to the original RoHS designation.

Phoenix Contact 1792627 (COMBICON CC Series)

This substitute provides functional equivalence with notable design differences. Electrical specifications meet IEC requirements (12A/400V) but UL current rating is reduced to 10A versus the original 15A. Housing material differs (LCP vs. PBT), offering superior thermal and chemical resistance. Contact tail length is significantly shorter (0.102" vs. 0.165"), requiring PCB design verification. Color is black rather than green. This part is suitable for applications where the reduced UL current rating is acceptable and where the enhanced material properties of LCP provide system benefits.

Frequently Asked Questions (FAQ)

Q: Can I use the 1776508 as a direct replacement for the 1899618 in existing designs?

A: The 1776508 is electrically and mechanically compatible with the 1899618 for applications requiring IEC 12A/400V or UL 15A/300V operation. The primary consideration is termination method: the 1776508 requires solder attachment versus press-fit for the original. Contact tail length differs (0.138" vs. 0.165"), so PCB through-hole depth must be verified. Both parts share identical pitch, position count, orientation, and shrouded male pin configuration.

Q: What is the difference between press-fit and solder termination?

A: Press-fit termination (1899618) uses mechanical insertion into plated through-holes without solder. Solder termination (1776508, 1792627) requires thermal bonding to PCB pads. Solder termination provides stronger mechanical retention and is standard in modern manufacturing. Press-fit termination offers faster assembly but is less common in current production.

Q: Can I use the 1792627 if my application requires 15A at UL ratings?

A: No. The 1792627 is rated for 10A at UL 300V, which is below the original 1899618 specification of 15A at UL 300V. Use the 1792627 only in applications where 10A UL current rating is acceptable.

Q: Does housing material affect electrical performance?

A: Both PBT (1899618, 1776508) and LCP (1792627) housings meet UL94 V-0 flammability requirements and maintain identical electrical ratings. LCP offers superior thermal stability and chemical resistance, which may benefit specific environmental conditions but does not change electrical specifications.

Q: Are there packaging differences between these parts?

A: The 1899618 is listed as obsolete with no specified packaging. The 1776508 and 1792627 are supplied in bulk packaging. Inventory availability differs: 1776508 has 1741 pieces in stock, 1792627 has 874 pieces, and 1899618 has 969 pieces available as legacy stock.

Q: What does the contact tail length difference mean for my PCB design?

A: Contact tail length determines how far the male pins extend into the PCB. The 1899618 has 0.165" tails, the 1776508 has 0.138" tails, and the 1792627 has 0.102" tails. Shorter tails require less through-hole depth. PCB design must accommodate the specific tail length of the selected part to ensure proper solder joint formation and mechanical stability.
