Weidmüller 995170 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995170 is a 21-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal mounting through PCB holes. This component features screw-clamping wire termination with side interlocking and is rated for 15 A at 300 V. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Substitute parts must maintain the same pitch, position count, mating orientation, and core electrical ratings while accommodating modern manufacturing standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 995170 is determined by the following critical parameters:

• Pitch and Position Count: All substitutes must maintain 0.200" (5.08mm) pitch with 21 positions per level to ensure PCB footprint compatibility.
• Mating Orientation and Mounting: Horizontal with board orientation and through-hole mounting are mandatory for direct replacement.
• Voltage Rating: Minimum 300 V rating required; higher ratings are acceptable.
• Current Rating: Minimum 15 A required; higher ratings are acceptable.
• Wire Gauge Compatibility: Must accommodate 12-26 AWG wire range or a subset thereof.
• Interlocking Feature: Side interlocking must be present for mechanical stability.
• Compliance: RoHS compliance and REACH unaffected status required for regulatory alignment.

The two identified substitutes meet these core criteria while offering improvements in product status (active vs. obsolete) and enhanced operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

Weidmüller 1330920000 is the primary substitute for the obsolete Weidmüller 995170. Both components are manufactured by Weidmüller and share identical pitch, position count, and mating orientation. The 1330920000 offers active product status, improved current rating (20 A vs. 15 A), extended operating temperature range (-50°C to 120°C), and screwless push-in termination technology. This part is suitable for direct replacement in new designs and production continuations where the enhanced thermal range and higher current capacity provide operational margin.

Eaton EM250521V serves as an alternative substitute from a different manufacturer. It maintains all critical mechanical and electrical parameters, including 21 positions, 0.200" pitch, horizontal through-hole mounting, and 300 V rating. The EM250521V provides 16 A current capacity and operates across -40°C to 105°C. This option is appropriate when Weidmüller supply is constrained or when the Eaton Euro-Mag series is preferred for system integration. The screw-based rising cage clamp termination is mechanically similar to the original design.

Both substitutes are RoHS compliant, REACH unaffected, and classified as EAR99 for export control purposes, maintaining regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1330920000 replace the 995170 in existing PCB designs?

A: Yes. Both parts share identical pitch (0.200"), position count (21), mating orientation (horizontal with board), and through-hole mounting. PCB footprints are compatible. The 1330920000 offers higher current capacity (20 A vs. 15 A) and extended temperature range, making it a direct mechanical and electrical upgrade.

Q: What is the primary difference between the Weidmüller 1330920000 and Eaton EM250521V?

A: The 1330920000 uses screwless push-in spring termination, while the EM250521V uses screw-based rising cage clamp termination. Both maintain the same pitch, position count, and voltage rating. The 1330920000 offers higher current capacity (20 A vs. 16 A) and wider temperature range (-50°C to 120°C vs. -40°C to 105°C). Selection depends on termination method preference and thermal requirements.

Q: Is the wire gauge range compatible across all three parts?

A: The 995170 and EM250521V both accept 12-26 AWG wire. The 1330920000 accepts 12-24 AWG, which covers most standard applications but excludes 25-26 AWG. Verify wire gauge requirements before selecting the 1330920000 for applications requiring larger gauge conductors.

Q: Are all three parts RoHS compliant?

A: Yes. The 995170, 1330920000, and EM250521V are all RoHS compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the impact of different termination methods on installation?

A: The 995170 and EM250521V use screw-based termination requiring a screwdriver and torque control (0.5-0.6 Nm for 995170; 0.56 Nm for EM250521V). The 1330920000 uses screwless push-in termination, eliminating the need for torque tools and reducing assembly time. Both methods are mechanically reliable; selection depends on assembly process and operator preference.
