Weidmüller 1553660000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1553660000 is an 11-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, and 90° wire entry orientation. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs. The part features screw-clamping termination, free-hanging mounting, and operates across -50°C to 100°C with IEC ratings of 15A at 400V and UL ratings of 10A at 300V.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1553660000 is determined by the following critical parameters:

Primary Compatibility Criteria:

• 11 positions with 0.200" (5.08mm) pitch (mechanical interface requirement)
• Female socket configuration (connector gender)
• Free-hanging in-line mounting type
• Screw-based termination style
• M2.5 screw size
• UL94 V-0 flammability rating

Secondary Compatibility Criteria:

• Wire gauge accommodation (minimum 12 AWG support required)
• Operating temperature range overlap
• Voltage and current ratings at or above original specifications
• Contact material and finish compatibility

Substitute Classification:

1. Direct Equivalent (1948100000): Weidmüller part with identical mechanical interface, enhanced electrical ratings, and active product status. Differs in insulation height and wire gauge upper limit.

2. Similar Substitute (OSTVM115551): On Shore Technology part with matching position count and pitch but different wire entry angle (180° vs. 90°), termination mechanism (pressure clip vs. clamping yoke), and contact material (steel vs. copper alloy).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Active Product Status):

The Weidmüller 1948100000 is the primary substitute for the obsolete 1553660000. Both parts maintain identical mechanical interfaces (11 positions, 5.08mm pitch, 90° wire entry, M2.5 screw termination) and identical housing materials (PBT). The 1948100000 offers enhanced electrical performance with IEC ratings of 23A at 400V (versus 15A) and UL ratings of 20A (versus 10A), supporting wire gauges up to 30 AWG. The 1948100000 carries RoHS Compliant certification and active product status, making it suitable for new designs and ongoing production.

For Alternative Substitution (Different Wire Entry Angle):

The On Shore Technology OSTVM115551 provides functional equivalence with critical differences. This part maintains the 11-position, 5.08mm pitch configuration and M2.5 screw termination but features 180° wire entry (straight entry versus 90° angled entry). The OSTVM115551 uses pressure clip termination instead of clamping yoke, steel contacts instead of copper alloy, and supports wire gauges 12-22 AWG. This substitute is suitable only when system layout accommodates straight wire entry and when the narrower wire gauge range (12-22 AWG versus 12-26 AWG) meets application requirements. The OSTVM115551 carries ROHS3 Compliant certification and active product status.

Frequently Asked Questions (FAQ)

Q: Can the 1948100000 directly replace the 1553660000 in existing installations?

A: Yes. Both parts share identical mechanical interfaces: 11 positions, 0.200" (5.08mm) pitch, 90° wire entry, M2.5 screw termination, and free-hanging mounting. The 1948100000 maintains the same housing material (PBT) and flammability rating (UL94 V-0). The primary difference is reduced insulation height (0.555" versus 1.059"), which may affect physical clearance in confined spaces. Verify mounting envelope compatibility before installation.

Q: What are the key differences between the 1948100000 and OSTVM115551?

A: The 1948100000 maintains the original 90° wire entry angle, while the OSTVM115551 features 180° straight entry. The 1948100000 uses copper alloy contacts with clamping yoke termination; the OSTVM115551 uses steel contacts with pressure clip termination. Wire gauge support differs: 1948100000 accommodates 12-30 AWG, while OSTVM115551 supports 12-22 AWG. The 1948100000 is Weidmüller (original manufacturer); the OSTVM115551 is On Shore Technology.

Q: Which substitute should I select for new designs?

A: The Weidmüller 1948100000 is recommended for new designs. It maintains manufacturer continuity, offers enhanced electrical ratings, supports a broader wire gauge range, and carries active product status with RoHS Compliant certification. Select the OSTVM115551 only if system layout requires 180° straight wire entry and the 12-22 AWG wire gauge range is sufficient.

Q: Are there packaging differences between these parts?

A: The 1553660000 original packaging is not specified. The 1948100000 is supplied in bulk packaging. The OSTVM115551 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Do all three parts meet the same compliance standards?

A: All three parts carry UL94 V-0 flammability rating and REACH Unaffected status. The 1553660000 compliance details are limited. The 1948100000 is RoHS Compliant. The OSTVM115551 is ROHS3 Compliant. For applications requiring specific compliance certifications, verify that the selected substitute meets your regulatory requirements.

Q: What is the impact of different contact materials on performance?

A: The 1553660000 and 1948100000 use copper alloy contacts, providing superior electrical conductivity and corrosion resistance. The OSTVM115551 uses steel contacts, which offer different contact resistance characteristics. For applications with stringent electrical performance requirements or corrosive environments, the copper alloy contact materials of the 1553660000 or 1948100000 are preferred.
