Weidmüller 1553460000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1553460000 is a 9-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, tin contact finish, and operates across -50°C to 100°C. Substitutes must maintain functional compatibility across electrical ratings, mechanical dimensions, and termination characteristics.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Position count and pitch: All substitutes must maintain 9 positions at 0.200" (5.08mm) spacing to ensure mechanical and electrical compatibility with mating connectors.
Wire entry orientation: The 90° orientation is a primary mechanical constraint. Substitutes with different orientations (such as 180° straight entry) represent functional variations requiring system redesign.
Termination method: Screw-based termination is mandatory. Variations in clamping mechanism (clamping yoke, rising cage clamp, pressure clip) are acceptable provided wire gauge compatibility is maintained.
Electrical ratings: Substitutes must meet or exceed the IEC current (15A) and voltage (400V) requirements. UL ratings are secondary compliance metrics.
Wire gauge compatibility: The acceptable wire gauge range (12-26 AWG / 0.2-2.5mm²) must overlap with the main part to ensure proper termination without modification.
Operating temperature range: Substitutes must support the full -50°C to 100°C operating window or a compatible subset.
Flammability and compliance: UL94 V-0 rating and REACH/RoHS status ensure regulatory alignment.

Engineering Selection Recommendations

1948070000 (Weidmüller - Direct Substitute)

This part is the primary equivalent. It maintains identical pitch, position count, wire entry orientation (90°), and termination method (screw clamping yoke). Electrical ratings exceed the main part (23A IEC vs. 15A IEC), ensuring full compatibility. Wire gauge range expands to 12-30 AWG, accommodating a broader conductor spectrum. Operating temperature range matches exactly (-50°C to 100°C). Product status is active with RoHS compliance, eliminating obsolescence concerns. Screw torque specifications are identical (0.4-0.5 Nm). This substitute requires no system redesign.

284047-9 (TE Connectivity - Similar Substitute)

This part maintains the critical parameters: 9 positions, 0.200" pitch, 90° wire entry, and free-hanging mounting. Termination differs (rising cage clamp vs. clamping yoke), but both are screw-based mechanisms compatible with the same wire gauges. UL current rating (15A) matches the main part; IEC rating is not specified. Wire gauge range (12-30 AWG / 0.05-3mm²) overlaps fully. Operating temperature range (-40°C to 110°C) exceeds the main part specification. Screw size increases to M3 with higher torque (0.79 Nm), requiring installation procedure adjustment. Product status is active with RoHS compliance. This substitute is functionally compatible with minor installation considerations.

OSTVM095551 (On Shore Technology - Conditional Substitute)

This part differs in wire entry orientation (180° straight vs. 90° angled), representing a significant mechanical variation. Position count, pitch, and free-hanging mounting remain compatible. Termination uses pressure clip (screw-based), differing from clamping mechanisms. Wire gauge range (12-22 AWG) is narrower than the main part, restricting conductor sizes above 22 AWG. Operating temperature range (-30°C to 105°C) is narrower at the lower bound. Contact finish is zinc instead of tin. Product status is active with ROHS3 compliance. This substitute is suitable only for applications where 180° wire entry orientation is acceptable and wire gauges do not exceed 22 AWG.

Frequently Asked Questions (FAQ)

Q: Can 1948070000 replace 1553460000 without system modifications?

A: Yes. The 1948070000 maintains identical mechanical and electrical compatibility. Pitch, position count, wire entry angle, and termination method are unchanged. Electrical ratings are higher, ensuring full backward compatibility. No system redesign is required.

Q: What is the primary difference between 284047-9 and the main part?

A: The termination mechanism differs (rising cage clamp vs. clamping yoke). Both are screw-based and compatible with the same wire gauges. The screw size increases from M2.5 to M3, requiring adjusted torque specifications (0.79 Nm vs. 0.4-0.5 Nm). Installation procedures must reflect this change.

Q: Why is OSTVM095551 listed as a conditional substitute?

A: The wire entry orientation is 180° (straight) instead of 90° (angled). This represents a functional variation requiring system redesign. Additionally, the wire gauge range is restricted to 12-22 AWG, excluding larger conductors. Use this substitute only when the application accommodates straight wire entry and conductor sizes remain within 12-22 AWG.

Q: Are all substitutes RoHS compliant?

A: Yes. The 1948070000 is RoHS Compliant, 284047-9 is RoHS Compliant, and OSTVM095551 is ROHS3 Compliant. All meet current environmental regulations.

Q: What is the impact of different contact materials (tin vs. zinc)?

A: Contact finish affects corrosion resistance and mating characteristics. Tin (main part and 1948070000, 284047-9) provides standard performance. Zinc (OSTVM095551) offers alternative corrosion properties. Selection depends on application environment and mating contact specifications.

Q: Can wire gauges larger than 22 AWG be used with OSTVM095551?

A: No. OSTVM095551 is rated for 12-22 AWG only. The main part and 1948070000 support up to 26 AWG and 30 AWG respectively. For applications requiring larger conductors, use 1948070000 or 284047-9.

Q: What are the operating temperature constraints for each substitute?

A: The main part operates -50°C to 100°C. The 1948070000 matches this range exactly. The 284047-9 extends to -40°C to 110°C (wider upper bound). The OSTVM095551 operates -30°C to 105°C (narrower lower bound). Select based on application temperature requirements.
