Weidmüller 995139 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995139 is an 11-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal mounting through PCB holes. This component belongs to the Omnimate LP series and features screw-clamping wire termination with side interlocking. The part is currently obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Weidmüller 995139 is determined by the following critical parameters:

• Pitch and Position Count: Both the main part and substitute must maintain 0.200" (5.08mm) pitch with 11 positions per level to ensure PCB footprint compatibility
• Mating Orientation: Horizontal with board orientation is required for mechanical fit
• Mounting Type: Through-hole mounting must be preserved
• Electrical Ratings: Voltage rating of 300 V is mandatory; current rating of the substitute must meet or exceed the 15 A requirement
• Wire Gauge Compatibility: The substitute wire gauge range must accommodate the 12-26 AWG specification of the original part
• Interlocking Feature: Side interlocking must be maintained for mechanical stability

The Weidmüller 1330810000 qualifies as a substitute based on these parameters. While it introduces design improvements (screwless termination, higher current rating, extended temperature range), it maintains all critical mechanical and electrical compatibility requirements.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1330810000 is the qualified substitute for the obsolete 995139 terminal block. Selection should be based on the following factors:

Product Status Consideration: The 995139 is obsolete, while the 1330810000 is active and currently in production. For new designs or system replacements, the 1330810000 is the appropriate choice to ensure long-term component availability.

Compliance and Certifications: The 1330810000 carries RoHS compliance certification, whereas the 995139 is not applicable. For applications subject to RoHS requirements, the 1330810000 fulfills regulatory obligations. Both parts maintain REACH Unaffected status.

Electrical Performance: The 1330810000 provides a 20 A current rating compared to the 995139's 15 A rating. This represents a performance enhancement with no compatibility compromise. The 300 V voltage rating is identical across both parts.

Mechanical Compatibility: Both components maintain identical pitch (0.200"/5.08mm), position count (11), mating orientation (horizontal with board), and mounting type (through hole). PCB footprint compatibility is preserved.

Termination Method Transition: The 1330810000 employs screwless push-in spring termination versus the 995139's screw-clamping method. This represents a design modernization that improves assembly efficiency while maintaining electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1330810000 be used as a direct replacement for the 995139 in existing PCB designs?

A: Yes. Both components share identical pitch (0.200"/5.08mm), 11-position configuration, horizontal board orientation, and through-hole mounting. PCB footprints are compatible. The primary difference is the termination method: the 1330810000 uses screwless push-in springs instead of screw clamping.

Q: What is the wire gauge compatibility difference between these parts?

A: The 995139 accepts 12-26 AWG wire, while the 1330810000 accepts 12-24 AWG wire. The 1330810000 does not accommodate 25-26 AWG wire. If your application requires 25-26 AWG termination, the 995139 specification must be maintained or an alternative component selected.

Q: Does the higher current rating of the 1330810000 (20 A vs. 15 A) affect compatibility?

A: No. A higher current rating in the substitute component does not create compatibility issues. The 1330810000 can safely handle applications designed for the 995139's 15 A specification. The increased rating provides additional design margin.

Q: Are there temperature range differences that affect application suitability?

A: Yes. The 1330810000 operates across -50°C to 120°C, while the 995139 operates across -20°C to 100°C. The 1330810000 provides extended temperature capability in both directions. For applications within the 995139's original temperature range, both components are suitable.

Q: What is the significance of the RoHS compliance difference?

A: The 1330810000 is RoHS compliant; the 995139 is not applicable. For applications subject to RoHS regulations (EU Directive 2011/65/EU), the 1330810000 meets compliance requirements. The 995139 cannot be used in RoHS-regulated applications.

Q: How does the termination method change affect assembly procedures?

A: The 995139 uses screw-clamping termination requiring torque application (0.5-0.6 Nm). The 1330810000 uses push-in spring termination requiring no torque specification. Assembly procedures must be updated to reflect the screwless termination method.

Q: Are both components available in the same packaging format?

A: The 995139 is listed with packaging designation "-" (not specified). The 1330810000 is supplied in bulk packaging. Verify packaging requirements for your procurement process.
