Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 995146 is based on the following critical parameters that must remain consistent:

• Pitch (0.200" / 5.08mm): Determines PCB footprint compatibility
• Position Count (18): Functional requirement for circuit connectivity
• Mating Orientation (Horizontal with Board): Physical installation constraint
• Mounting Type (Through Hole): PCB assembly method
• Voltage Rating (300 V minimum): Electrical safety requirement
• Current Rating (15 A minimum): Load-carrying capacity requirement
• Wire Gauge Compatibility (12-26 AWG minimum range): Conductor accommodation

The substitute part Weidmüller 1330890000 meets all critical substitution criteria while offering enhanced electrical performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1330890000 is the qualified substitute for the obsolete 995146 based on the following factors:

Compliance & Regulatory: Both parts maintain RoHS compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental directives.

Electrical Performance: The substitute part exceeds the original specifications with a 20 A current rating versus 15 A, while maintaining the same 300 V voltage rating. This provides additional design margin for existing circuits.

Product Status: The 1330890000 holds active product status, ensuring long-term availability and manufacturing support, whereas the 995146 is obsolete and subject to discontinuation.

Physical Compatibility: Both parts share identical pitch (5.08mm), position count (18), mating orientation (horizontal with board), and through-hole mounting type, ensuring direct PCB footprint compatibility.

Termination Method Difference: The substitute employs screwless push-in spring termination versus screw-clamping termination on the original. This represents a functional change requiring assembly process evaluation.

Temperature Range Enhancement: The 1330890000 extends the operating temperature range to -50°C ~ 120°C compared to -20°C ~ 100°C, providing broader environmental capability.

Frequently Asked Questions (FAQ)

Q: Can the 1330890000 be used as a direct drop-in replacement for the 995146?

A: The 1330890000 maintains identical PCB footprint compatibility due to matching pitch (5.08mm), position count (18), and through-hole mounting. However, the termination method differs: the substitute uses screwless push-in spring termination instead of screw-clamping. Assembly procedures must be updated accordingly.

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

A: The 995146 accepts 12-26 AWG wire, while the 1330890000 accepts 12-24 AWG wire. The substitute has a narrower upper limit. Verify that existing wire gauges in your application fall within the 12-24 AWG range.

Q: Does the higher current rating of the 1330890000 affect circuit design?

A: The 20 A rating of the 1330890000 exceeds the 15 A requirement of the 995146. This provides additional capacity margin and does not require circuit redesign for applications operating within the original 15 A specification.

Q: Are there packaging differences between these parts?

A: The 995146 is listed with no specified packaging, while the 1330890000 is supplied in bulk packaging. Confirm bulk packaging meets your procurement and handling requirements.

Q: What is the impact of the different housing materials?

A: The 995146 uses Polyamide (PA66) / Nylon 6/6, while the 1330890000 uses Thermoplastic Wemid. Both materials provide suitable electrical insulation and mechanical properties for terminal block applications. Material selection should be evaluated based on specific environmental exposure in your application.

Q: Are both parts suitable for the same voltage and temperature applications?

A: Both parts are rated for 300 V. The 1330890000 provides an extended operating temperature range (-50°C ~ 120°C) compared to the 995146 (-20°C ~ 100°C), making it suitable for a broader range of thermal environments.
