Equivalent & Substitute Parts for Weidmüller 1785830000

Part Overview

The Weidmüller 1785830000 is a 4-position wire-to-board terminal block with vertical mating orientation and 0.200" (5.08mm) pitch spacing. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The part operates at 10 A current capacity with 300 V voltage rating and supports wire gauges from 14-22 AWG through screw-clamp termination.

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1785830000 is determined by the following critical parameters:

Position Count: All substitutes maintain 4-position configuration
Pitch Spacing: Substitutes operate at either 0.197" (5.00mm) or 0.200" (5.08mm) pitch
Voltage & Current Ratings: All substitutes meet or exceed 300 V and 10 A minimum requirements
Wire Gauge Compatibility: All substitutes accept 14-22 AWG wire range
Mounting Type: All substitutes use through-hole PCB mounting
Wire Termination Method: Substitutes employ screw-based termination (TOP clamp or leaf spring variants)
Regulatory Compliance: All substitutes maintain RoHS and REACH compliance

The primary distinction among substitutes is mating orientation: the original part features vertical entry, while available substitutes employ horizontal (side-entry) configurations. This orientation difference requires PCB layout modification during implementation.

Engineering Selection Recommendations

All three On Shore Technology substitutes (ED500/4DS, OSTTA044163, OSTTC040162) are active products with current manufacturing support and ROHS3 compliance certification, providing supply chain continuity for the obsolete Weidmüller 1785830000.

OSTTA044163 provides the closest electrical and mechanical alignment to the original part, maintaining the 0.200" (5.08mm) pitch specification while offering enhanced current capacity (15 A versus 10 A) and extended operating temperature range (-30°C to 105°C versus -20°C to 100°C). This part requires PCB layout modification due to horizontal mating orientation but eliminates pitch conversion complexity.

OSTTC040162 operates at 0.197" (5.00mm) pitch and includes interlocking side-entry features with zinc-plated steel screw hardware. This configuration requires both orientation and pitch-spacing PCB modifications but provides the highest inventory availability (28,572 units in stock).

ED500/4DS operates at 0.197" (5.00mm) pitch with leaf spring and wire guard termination. This option similarly requires pitch conversion during implementation.

Selection between these substitutes depends on PCB layout constraints and tolerance for pitch modification. Pitch-matched substitution (OSTTA044163) minimizes design revision scope.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1785830000 be directly replaced without PCB modification?

A: Direct replacement without PCB modification is not possible. The original part features vertical mating orientation, while all available substitutes employ horizontal (side-entry) configurations. PCB layout modification is required for any substitute implementation.

Q: Which substitute maintains the original pitch spacing?

A: OSTTA044163 maintains the 0.200" (5.08mm) pitch specification of the original Weidmüller part. ED500/4DS and OSTTC040162 operate at 0.197" (5.00mm) pitch and require pitch-spacing adjustment during PCB redesign.

Q: Are all substitutes electrically compatible with the original part's 10 A rating?

A: Yes. All three substitutes are rated for 15 A current capacity, exceeding the original 10 A specification. All maintain 300 V voltage rating and support 14-22 AWG wire gauge compatibility.

Q: What is the primary difference in wire termination between the original and substitutes?

A: The Weidmüller 1785830000 uses TOP clamp screw termination. All On Shore substitutes employ leaf spring with wire guard screw termination, providing enhanced wire retention characteristics.

Q: Which substitute offers the best supply availability?

A: OSTTC040162 provides the highest inventory level at 28,572 units in stock, followed by OSTTA044163 at 1,577 units and ED500/4DS at 1,124 units.

Q: Do all substitutes meet current RoHS compliance requirements?

A: Yes. All three substitutes carry ROHS3 certification, exceeding the RoHS Compliant status of the original Weidmüller part. All maintain REACH Unaffected classification.
