Weidmüller 1554410000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1554410000 is a 19-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, and 90° wire entry configuration. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs requiring compatible connectivity solutions. The part operates within IEC 400V/15A and UL 300V/10A specifications, supporting wire gauges from 12-26 AWG (0.2-2.5mm²).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1554410000 is determined by the following critical parameters:

Direct Compatibility Requirements:

• 19-position configuration
• 0.200" (5.08mm) pitch spacing
• Female socket type
• Free hanging (in-line) mounting
• Screw termination method
• M2.5 screw size
• UL94 V-0 flammability rating
• Operating temperature range support

Acceptable Parameter Variations:

• Wire entry angle (90° vs. 180°) - affects installation geometry but maintains electrical function
• Current rating differences - substitute must meet or exceed application requirements
• Wire gauge range expansion - substitute supporting broader gauge ranges is acceptable
• Termination mechanism variation (clamping yoke vs. pressure clip) - both provide secure screw-based termination
• Contact material and housing material differences - provided electrical and mechanical performance is maintained
• Insulation height variation - does not affect electrical compatibility

Engineering Selection Recommendations

Weidmüller 1948410000 (Direct Substitute)

The 1948410000 is the primary equivalent for the obsolete 1554410000. Both components share identical pitch, position count, wire entry angle, and termination method. The 1948410000 maintains active product status with improved current ratings (23A IEC / 20A UL versus 15A IEC / 10A UL) and expanded wire gauge support (12-30 AWG versus 12-26 AWG). Both parts are RoHS compliant with UL94 V-0 flammability rating and identical operating temperature range. This substitute provides direct form-fit-function replacement with enhanced electrical capacity.

On Shore Technology OSTVM195551 (Alternative Substitute)

The OSTVM195551 provides functional equivalence with notable geometric and material differences. Wire entry orientation is 180° (straight) versus 90° (right-angle), requiring different installation geometry. Termination employs pressure clip method rather than clamping yoke, though both utilize M2.5 screw fastening. Wire gauge support is narrower (12-22 AWG), and contact material is steel rather than copper alloy. This substitute is suitable when installation space accommodates straight wire entry and wire gauge requirements fall within 12-22 AWG range. Active product status and UL94 V-0 compliance support long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the 1948410000 directly replace the 1554410000 without modification?

A: Yes. Both components feature identical 19-position configuration, 5.08mm pitch, 90° wire entry, and M2.5 screw termination. The 1948410000 is a direct form-fit-function replacement with enhanced electrical ratings and broader wire gauge compatibility.

Q: What is the primary difference between the 1948410000 and OSTVM195551?

A: The 1948410000 maintains 90° wire entry identical to the original part, while the OSTVM195551 features 180° straight wire entry. Additionally, the OSTVM195551 uses pressure clip termination versus clamping yoke, and supports a narrower wire gauge range (12-22 AWG). Selection depends on installation geometry and wire gauge requirements.

Q: Are all three parts RoHS compliant?

A: Yes. The 1554410000 and 1948410000 are RoHS compliant. The OSTVM195551 is ROHS3 compliant. All three meet current environmental regulatory requirements.

Q: What wire gauges does each part support?

A: The 1554410000 supports 12-26 AWG (0.2-2.5mm²). The 1948410000 supports 12-30 AWG (0.2-4mm²), providing the broadest range. The OSTVM195551 supports 12-22 AWG, the most restrictive range.

Q: Can I use the OSTVM195551 if my application requires 26 AWG wire?

A: No. The OSTVM195551 maximum wire gauge is 22 AWG. For 26 AWG wire, use either the 1554410000 or 1948410000.

Q: What is the current rating difference between the main part and substitutes?

A: The 1554410000 is rated 15A (IEC) / 10A (UL). The 1948410000 is rated 23A (IEC) / 20A (UL). The OSTVM195551 is rated 20A (UL) with no IEC rating specified. Both substitutes meet or exceed the original part's current capacity.

Q: Are the operating temperature ranges compatible?

A: The 1554410000 and 1948410000 both operate -50°C to 100°C. The OSTVM195551 operates -30°C to 105°C. For applications below -30°C, use the Weidmüller parts. For applications above 100°C, use the OSTVM195551.

Q: What packaging is available for each part?

A: The 1554410000 packaging is not specified. The 1948410000 and OSTVM195551 are supplied in bulk packaging.
