Weidmüller 1503660000 Terminal Block Plug – Equivalent & Substitute Parts

Part Overview

The Weidmüller 1503660000 is a 20-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, and 180° free-hanging (in-line) mounting. This component is part of the Omnimate BL series and is classified as obsolete. Due to its discontinued status, equivalent substitute parts from active manufacturers are necessary to maintain system compatibility and ensure long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Weidmüller 1503660000 are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• 20-position configuration
• Female socket type
• Pitch tolerance (0.200" / 5.08mm or 0.197" / 5.00mm)
• Free-hanging (in-line) mounting
• Screw termination style
• UL94 V-0 flammability rating
• Tin contact mating finish

Secondary Considerations:

• Wire gauge compatibility (12-30 AWG range acceptable)
• Voltage and current ratings (UL 300V / 15A minimum)
• Retention latch configuration
• Product status (active preferred for obsolete parts)

The substitute parts listed below meet these criteria with variations in wire entry angle (90°, 180°, 270°), housing material, and screw clamp mechanism (rising cage clamp vs. top clamp). These variations allow for direct functional substitution in applications where the specific wire entry orientation and clamp style are compatible with the system design.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (180° Wire Entry):

For applications requiring the same 180° wire entry orientation as the original Weidmüller 1503660000, the Phoenix Contact 1757190 is the primary active substitute. Both parts share identical pitch (0.200" / 5.08mm) and wire entry angle. The Phoenix Contact part offers higher current capacity (15A UL vs. 10A UL) and superior voltage rating (630V IEC vs. 400V IEC), making it suitable for equivalent or more demanding applications. The rising cage clamp termination provides equivalent screw-based connection reliability.

Alternative Orientations (90° or 270° Wire Entry):

When system layout permits alternative wire entry angles, the Amphenol PCD ELFF series (ELFF20230 for 90°, ELFF20240 for 270°) offers active product status with 0.200" (5.08mm) pitch matching. These parts maintain full electrical compatibility (15A UL, 300V UL) and UL94 V-0 flammability compliance. The ELFF series uses polyphenylene oxide (PPO) housing, which differs from the original PBT material but meets the same flammability standard.

Pitch Tolerance Consideration:

The Amphenol PCD ELFF20130 and ELFF20140 operate at 0.197" (5.00mm) pitch, representing a 0.03mm deviation from the original 0.200" (5.08mm) specification. These parts are suitable only when mechanical tolerance analysis confirms compatibility with the mating connector or header.

Compliance and Supply Chain:

All substitute parts carry active product status and RoHS compliance certification, ensuring long-term availability and regulatory alignment. The Weidmüller 1503660000 obsolete status necessitates transition to one of these active alternatives for new designs or system maintenance requiring component replenishment.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1757190 directly replace the Weidmüller 1503660000?

A: Yes, for applications where 180° wire entry is required. Both parts share 0.200" (5.08mm) pitch, 20-position configuration, and female socket type. The Phoenix Contact part has higher electrical ratings (15A UL, 630V IEC) and uses a rising cage clamp instead of a top clamp, but both are screw-based termination methods suitable for equivalent connection reliability.

Q: What is the difference between the Amphenol ELFF20230 and ELFF20240?

A: Both parts are identical except for wire entry angle. ELFF20230 has 90° wire entry, while ELFF20240 has 270° wire entry. Both use 0.200" (5.08mm) pitch and are suitable substitutes when the system layout accommodates these alternative orientations.

Q: Are the Amphenol ELFF20130 and ELFF20140 compatible with the original Weidmüller part?

A: These parts have 0.197" (5.00mm) pitch instead of 0.200" (5.08mm). Compatibility depends on mechanical tolerance analysis of the mating connector or header. The 0.03mm pitch difference may be acceptable in some applications but requires verification before implementation.

Q: Why do substitute parts have different housing materials?

A: The Phoenix Contact 1757190 uses polyamide (PA) nylon, while Amphenol ELFF series uses polyphenylene oxide (PPO). The Weidmüller original uses PBT glass-filled plastic. All materials meet UL94 V-0 flammability requirements. Material selection affects thermal performance and chemical resistance; verify compatibility with the operating environment.

Q: Do all substitute parts support the same wire gauge range?

A: The original Weidmüller part accepts 14-26 AWG (0.2-2.5mm²). All substitute parts accept 12-30 AWG or 12 AWG plus 14-26 AWG, providing equal or broader wire gauge compatibility. Verify that the specific wire gauge used in your application falls within the acceptable range for your selected substitute.

Q: What is the difference between TOP clamp and rising cage clamp termination?

A: Both are screw-based termination methods. TOP clamp (original Weidmüller) secures the wire from above, while rising cage clamp (all substitutes) uses a cage mechanism that rises as the screw tightens. Both methods provide secure electrical connection; the choice depends on system design and assembly procedure compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Phoenix Contact 1757190 is ROHS3 compliant, and all Amphenol ELFF series parts are RoHS compliant. The original Weidmüller part does not specify RoHS status. For new designs or systems requiring RoHS certification, all listed substitutes meet this requirement.

Q: What is the current inventory status of these substitute parts?

A: Phoenix Contact 1757190: 912 pcs in stock. Amphenol ELFF20130: 1013 pcs. Amphenol ELFF20140: 1061 pcs. Amphenol ELFF20230: 949 pcs. Amphenol ELFF20240: 931 pcs. All substitutes have active product status and established supply chains.
