Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1899000000 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 20
• Pitch: 0.197" (5.00mm)
• Plug Wire Entry: 90°
• Type: Plug, Female Sockets
• Termination Style: Screw - Clamping Yoke (Tension Sleeve)
• Mounting Type: Free Hanging (In-Line)
• Contact Material: Copper Alloy
• Housing Material: Polybutylene Terephthalate (PBT)
• Contact Mating Finish: Tin
• Material Flammability Rating: UL94 V-0

Allowable Parameter Variations:

• Current Rating: May increase (IEC 15A → 23A; UL 10A → 20A)
• Voltage Rating: May remain equal or increase
• Wire Gauge Range: May expand (12-26 AWG → 12-30 AWG; 0.2-2.5mm² → 0.2-4mm²)
• Operating Temperature: May be specified (from unspecified to -50°C ~ 100°C)
• Insulation Height: May vary (0.555" to 1.071")
• Screw Size: May be specified (from unspecified to M2.5)
• Product Status: May transition from Obsolete to Active

The substitute part 1959270000 meets all mandatory matching criteria and demonstrates allowable parameter enhancements in current capacity, wire gauge accommodation, and operating temperature specification.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1959270000 is a direct substitute for the obsolete 1899000000 terminal block plug. Both components are manufactured by Weidmüller within the Omnimate BL series and share identical mechanical and electrical interface specifications.

The substitute part 1959270000 offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Enhanced current ratings (IEC 23A vs. 15A; UL 20A vs. 10A) provide increased capacity margin
• Expanded wire gauge accommodation (12-30 AWG vs. 12-26 AWG; 0.2-4mm² vs. 0.2-2.5mm²) supports broader conductor sizes
• Specified operating temperature range (-50°C ~ 100°C) provides defined thermal performance envelope
• Both parts maintain identical RoHS compliance and REACH unaffected status
• Both parts carry UL94 V-0 flammability rating

The increased insulation height (1.071" vs. 0.555") and specified screw size (M2.5) in the substitute part represent design refinements within the Omnimate BL series evolution. These dimensional changes do not affect functional compatibility for standard mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the 1959270000 directly replace the 1899000000 in existing installations?

A: Yes. Both parts share identical position count (20), pitch (5.00mm), wire entry angle (90°), termination method (screw-clamping), and mounting configuration (free-hanging in-line). The substitute part maintains mechanical and electrical interface compatibility.

Q: What is the significance of the higher current ratings in the 1959270000?

A: The 1959270000 is rated for IEC 23A (vs. 15A) and UL 20A (vs. 10A). This represents enhanced current-carrying capacity in the substitute design. Applications operating at or below the original part's current limits remain fully compatible.

Q: Does the expanded wire gauge range of the 1959270000 affect compatibility?

A: No. The 1959270000 accommodates 12-30 AWG (0.2-4mm²) compared to the original 12-26 AWG (0.2-2.5mm²). This expanded range is a design enhancement that maintains backward compatibility with the original part's wire gauge specifications.

Q: Why is the operating temperature specified in the 1959270000 but not in the 1899000000?

A: The 1959270000 provides an explicit operating temperature range of -50°C ~ 100°C. This specification represents a design refinement in the Omnimate BL series. Both parts are suitable for standard industrial temperature environments.

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

A: No. Both the 1899000000 and 1959270000 are RoHS compliant, REACH unaffected, and carry UL94 V-0 flammability ratings. Regulatory compliance is equivalent.

Q: What is the impact of the different insulation heights?

A: The 1959270000 has an insulation height of 1.071" (27.20mm) compared to 0.555" (14.10mm) in the 1899000000. This dimensional difference reflects design evolution within the Omnimate BL series and does not affect electrical performance or standard mounting compatibility.

Q: Is the M2.5 screw size specification in the 1959270000 a compatibility concern?

A: No. The M2.5 screw size in the 1959270000 is a design specification that does not affect compatibility with existing connector housings or mating components. Termination torque remains identical (0.4-0.5 Nm) for both parts.
