Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Weidmüller 1851510000 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 11
• Pitch: 0.200" (5.08mm)
• Type: Plug with female sockets
• Mounting type: Free hanging (in-line)
• Wire gauge compatibility: 12-26 AWG (0.2-2.5mm²)
• Operating temperature range: -50°C to 100°C
• Housing material: Polybutylene Terephthalate (PBT)
• Contact material: Copper alloy
• Flammability rating: UL94 V-0

Allowable Variations:

• Termination style: Different spring mechanisms (tension clamp vs. leg spring/push-in spring)
• Current rating: May exceed original specification (17A IEC / 15A UL)
• Voltage rating: Must meet or exceed original specification (400V IEC / 300V UL)
• Product status: Active parts are preferred over obsolete
• Ingress protection: Addition of IP20 rating is acceptable
• RoHS compliance: Addition of RoHS compliance is acceptable

The Weidmüller 1014470000 qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1014470000 is the direct substitute for the obsolete 1851510000. Selection is based on the following engineering criteria:

Product Status: The 1014470000 is active and currently manufactured, whereas the 1851510000 is obsolete. For new designs and ongoing procurement, the 1014470000 is the appropriate choice.

Electrical Compatibility: The 1014470000 meets or exceeds all electrical specifications of the original part. Current ratings are higher (24A IEC, 18.5A UL versus 17A IEC, 15A UL), and voltage ratings are identical (400V IEC, 300V UL). This provides improved performance margin without compromising system design.

Mechanical Compatibility: Both parts share identical pitch (5.08mm), position count (11), wire gauge range (12-26 AWG), and mounting configuration (free hanging, in-line). Physical dimensions and connector interface are compatible.

Compliance and Certifications: The 1014470000 carries RoHS compliance and IP20 ingress protection, both improvements over the original specification. Both parts maintain UL94 V-0 flammability rating and operate across the same temperature range (-50°C to 100°C).

Termination Mechanism: The 1014470000 uses a leg spring and push-in spring termination style, compared to the original tension clamp design. Both are screwless mechanisms suitable for the same application class.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1014470000 directly replace the 1851510000 in existing installations?

A: Yes. The 1014470000 is mechanically and electrically compatible with the 1851510000. Both parts have identical pitch (5.08mm), 11 positions, female socket configuration, and free-hanging mounting. Electrical ratings of the substitute meet or exceed the original specification.

Q: What is the difference in termination style between these parts?

A: The 1851510000 uses a spring cage with tension clamp termination, while the 1014470000 uses a leg spring with push-in spring termination. Both are screwless mechanisms designed for the same wire gauge range (12-26 AWG). The functional outcome is equivalent wire retention and electrical connection.

Q: Does the higher current rating of the 1014470000 affect compatibility?

A: No. The 1014470000 current rating (24A IEC, 18.5A UL) exceeds the original specification (17A IEC, 15A UL). This provides additional performance margin and does not create compatibility issues. The substitute can safely handle applications designed for the original part.

Q: Is the 1014470000 available in the same packaging as the 1851510000?

A: The 1014470000 is supplied in box packaging. The original 1851510000 packaging specification was not provided. Confirm packaging requirements with your procurement department if specific packaging is required for your application.

Q: What is the significance of the IP20 rating on the 1014470000?

A: The 1014470000 includes IP20 ingress protection, which the original 1851510000 did not specify. IP20 provides protection against solid objects larger than 12mm and is suitable for indoor industrial environments. This is an enhancement that does not affect backward compatibility.

Q: Are both parts RoHS compliant?

A: The 1014470000 is RoHS compliant. RoHS compliance status was not specified for the original 1851510000. If RoHS compliance is a requirement for your application, the 1014470000 meets this standard.

Q: What is the wire strip length for both parts?

A: Both the 1851510000 and 1014470000 have a wire strip length of 10mm, ensuring consistent preparation requirements for wire termination.
