Weidmüller 1753810000 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1753810000 is a 2-position wire-to-board terminal block with vertical mounting and 0.200" (5.08mm) pitch spacing. This component is part of the Omnimate LP series and is classified as obsolete. The part features screw-clamping wire termination with a rated current of 20 A and voltage of 300 V, designed for through-hole PCB mounting applications. Due to its obsolete status, identifying equivalent substitute parts from the active product portfolio is necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

The Weidmüller 1994250000 qualifies as a direct substitute for the 1753810000 based on the following critical parameters:

Identical positions per level (2)
Identical pitch spacing (0.200" / 5.08mm)
Identical mating orientation (vertical with board)
Identical current rating (20 A)
Identical voltage rating (300 V)
Identical wire gauge acceptance (12-26 AWG)
Identical mounting type (through hole)
Identical wire termination method (screw - clamping yoke, tension sleeve)
Identical screw thread specification (M3)
Identical torque specification (0.5-0.6 Nm)

The primary difference is that the 1994250000 belongs to the Omnimate LL series and maintains an active product status, whereas the 1753810000 is obsolete. The 1994250000 also features an extended operating temperature range (-50°C to 120°C versus -50°C to 100°C) and uses Thermoplastic Wemid housing material instead of Polyamide (PA) Nylon.

Engineering Selection Recommendations

The Weidmüller 1994250000 is the appropriate substitute for the obsolete 1753810000. Both parts maintain identical electrical specifications (20 A current, 300 V voltage), mechanical compatibility (2-position, 5.08mm pitch, through-hole mounting), and termination characteristics (M3 screw thread, 0.5-0.6 Nm torque). The 1994250000 is currently in active production status with 996 units in stock, ensuring procurement availability.

The 1994250000 provides an extended operating temperature range (-50°C to 120°C) compared to the original part (-50°C to 100°C), which represents an improvement for thermal margin in applications. Both parts carry identical export classification (EAR99) and tariff codes (8536.90.4000), confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 1994250000 be used as a direct replacement for the 1753810000 in existing designs?

A: Yes. The 1994250000 maintains identical electrical ratings (20 A, 300 V), mechanical pitch (5.08mm), mounting type (through-hole), and termination method (M3 screw). PCB footprints and wire gauge acceptance (12-26 AWG) are identical, enabling direct substitution without design modification.

Q: What is the difference in housing material between these parts?

A: The 1753810000 uses Polyamide (PA) Nylon housing, while the 1994250000 uses Thermoplastic Wemid. Both materials provide equivalent mechanical and electrical performance within the specified operating temperature ranges.

Q: Does the extended temperature range of the 1994250000 affect compatibility?

A: No. The 1994250000 operates from -50°C to 120°C, compared to -50°C to 100°C for the 1753810000. This extended range is a performance enhancement that does not compromise compatibility in applications operating within the original temperature specification.

Q: Are the packaging formats different between these parts?

A: The 1753810000 was supplied in standard packaging, while the 1994250000 is supplied in bulk packaging. This difference affects procurement and handling but does not impact electrical or mechanical performance.

Q: Do both parts have the same screw torque specification?

A: Yes. Both the 1753810000 and 1994250000 require identical screw torque of 0.5-0.6 Nm (4.4-5.3 Lb-In) for M3 fasteners, ensuring consistent assembly procedures.
