Weidmüller 995148 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995148 is a 20-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal mounting with through-hole PCB installation. This component operates at 15 A and 300 V, featuring screw-clamping wire termination and side interlocking. The 995148 carries an obsolete product status, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The Weidmüller 1330910000 qualifies as a functional equivalent based on the following critical parameters:

Matching Parameters:

• 20 positions per level
• 0.200" (5.08mm) pitch spacing
• 300 V voltage rating
• Horizontal with board mating orientation
• Through-hole mounting type
• Side interlocking feature
• Orange housing color
• RoHS compliant
• REACH unaffected status

Allowable Variations:

• Current rating increased from 15 A to 20 A (higher capacity acceptable)
• Wire gauge range adjusted from 12-26 AWG to 12-24 AWG (subset of original range)
• Wire termination changed from screw-clamping to screwless push-in spring (different mechanism, same function)
• Operating temperature range expanded from -20°C ~ 100°C to -50°C ~ 120°C (wider range acceptable)
• Housing material changed from Polyamide (PA66) to Thermoplastic Wemid (equivalent polymer class)
• Product status changed from obsolete to active (ensures ongoing availability)

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1330910000 is the active equivalent for the obsolete 995148 model. Selection of the 1330910000 is supported by:

• Regulatory Compliance: Both parts maintain RoHS compliance and REACH unaffected status, ensuring regulatory continuity.
• Product Availability: The 1330910000 carries active product status with confirmed inventory, whereas the 995148 is obsolete and subject to supply discontinuation.
• Electrical Compatibility: The 1330910000 meets or exceeds the electrical specifications of the 995148 (20 A vs. 15 A current rating, identical 300 V voltage rating).
• Mechanical Compatibility: Identical pitch (5.08mm), position count (20), mounting type (through-hole), and mating orientation ensure direct PCB footprint compatibility.
• Functional Equivalence: Both parts provide side interlocking and identical connector interface geometry, supporting drop-in replacement in existing designs.

The primary design consideration is the termination method change from screw-clamping to push-in spring. This transition requires verification that the push-in spring mechanism is compatible with the intended wire gauge range (12-24 AWG for the 1330910000 vs. 12-26 AWG for the 995148).

Frequently Asked Questions (FAQ)

Q: Can the 1330910000 directly replace the 995148 on existing PCBs?

A: Yes. Both parts share identical pitch (5.08mm), position count (20), through-hole mounting type, and horizontal board orientation. PCB footprints are compatible without modification.

Q: What is the impact of the wire termination change from screw-clamping to push-in spring?

A: The termination mechanism differs, but both provide equivalent wire retention and electrical connection. The push-in spring method (1330910000) eliminates the need for torque-controlled screw assembly, potentially simplifying installation. Verify that wire gauges within the 12-24 AWG range are compatible with your application.

Q: Does the expanded operating temperature range of the 1330910000 affect compatibility?

A: No. The 1330910000 operating range (-50°C ~ 120°C) encompasses the original 995148 range (-20°C ~ 100°C). This expansion provides additional thermal margin and does not introduce compatibility issues.

Q: Are there packaging differences between the two parts?

A: The 995148 is listed with no specified packaging, while the 1330910000 is supplied in bulk packaging. Confirm bulk packaging meets your procurement and handling requirements.

Q: Is the housing material change from PA66 to Wemid thermoplastic significant?

A: Both materials are engineering-grade thermoplastics suitable for terminal block applications. Wemid is a polyamide-based thermoplastic offering equivalent mechanical and thermal properties to PA66 within the specified operating range.

Q: What is the current rating difference, and does it matter?

A: The 1330910000 is rated for 20 A compared to the 995148 at 15 A. The higher rating provides additional current capacity and does not restrict use in applications requiring 15 A or less. No derating is necessary.
