Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899799 is determined by the following critical parameters:

Primary Matching Criteria:

• Number of positions: 20
• Pitch: 0.200" (5.08mm)
• Type: Header, Male Pins, Shrouded (4 Side)
• Header orientation: 90°, Right Angle
• Mounting type: Through Hole
• Current rating (IEC): 12A minimum
• Voltage rating (IEC): 400V minimum
• Material flammability: UL94 V-0

Secondary Compatibility Factors:

• Contact mating finish: Tin
• Housing material: PBT or equivalent
• RoHS compliance status

The identified substitute parts (1776689 and 1827595) maintain all primary matching criteria. Variations in termination style (press-fit versus solder), contact tail length, and housing material composition represent acceptable engineering trade-offs within the terminal block header category, provided electrical and mechanical specifications remain within acceptable ranges.

Parameter Comparison

Engineering Selection Recommendations

For 1776689 (COMBICON MSTB Series): This substitute maintains identical electrical specifications (12A IEC, 400V IEC) and mechanical configuration. The primary difference is termination style conversion from press-fit to solder. This part is currently active in production and carries ROHS3 compliance certification, providing superior long-term availability and regulatory alignment compared to the obsolete 1899799. The reduced contact tail length (4.60mm versus 4.19mm) requires PCB layout verification but remains within acceptable through-hole mounting parameters.

For 1827595 (COMBICON CC Series): This substitute provides active product status with enhanced UL current rating (16A versus 15A). The IEC voltage rating is reduced to 320V, which remains acceptable for most industrial applications operating at or below 400V nominal. Housing material differs (LCP versus PBT), offering improved thermal and chemical resistance characteristics. The significantly shorter contact tail length (2.60mm) necessitates PCB design review to ensure adequate solder joint formation and mechanical stability.

Both substitutes are manufactured by Phoenix Contact and maintain the critical 20-position, 5.08mm pitch, right-angle through-hole header configuration with full shrouding and UL94 V-0 flammability rating.

Frequently Asked Questions (FAQ)

Q: Can 1776689 or 1827595 be used as direct replacements for 1899799 in existing designs?

A: Both parts maintain identical position count, pitch, orientation, and shrouding configuration. However, termination style differs: 1899799 uses press-fit termination while both substitutes use solder termination. PCB footprints and assembly processes must be evaluated. Contact tail length variations (1899799: 4.19mm, 1776689: 4.60mm, 1827595: 2.60mm) require verification against PCB hole depth and solder joint requirements.

Q: What is the significance of the voltage rating difference between 1776689 and 1827595?

A: Part 1776689 maintains the full 400V IEC rating of the original 1899799, while 1827595 is rated at 320V IEC. For applications operating at 400V nominal or higher, 1776689 is the appropriate selection. For applications at 320V or below, 1827595 is acceptable and offers enhanced UL current rating (16A).

Q: Are there compliance differences between the substitute parts?

A: Part 1776689 carries ROHS3 certification, representing the most current regulatory compliance standard. Part 1827595 carries RoHS Compliant certification. Both meet UL94 V-0 flammability requirements. For new designs or long-term supply chain planning, ROHS3 compliance (1776689) provides superior regulatory alignment.

Q: How do housing material differences affect component selection?

A: The original 1899799 uses PBT (Polybutylene Terephthalate), as does substitute 1776689. Substitute 1827595 uses LCP (Liquid Crystal Polymer), which offers superior thermal stability and chemical resistance. Both materials meet UL94 V-0 flammability requirements. Material selection depends on operating environment and thermal management requirements.

Q: What assembly process changes are required when switching from 1899799 to the substitute parts?

A: The primary process change involves termination method: 1899799 requires press-fit assembly, while 1776689 and 1827595 require solder termination. This necessitates PCB design modifications, assembly process changes, and potential equipment updates. Contact tail length variations must be accommodated in PCB hole sizing and solder joint design.
