Weidmüller 1553810000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1553810000 is a 13-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, and 90° wire entry configuration. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs requiring compatible connectivity solutions. The plug features screw-clamping termination, tin-plated copper alloy contacts, 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

Substitute parts for the 1553810000 are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• 13 positions with 0.200" (5.08mm) pitch spacing
• Female socket configuration
• Free hanging (in-line) mounting type
• Screw-based termination mechanism
• Polybutylene Terephthalate (PBT) or equivalent housing material
• UL94 V-0 flammability rating
• Operating temperature range encompassing -50°C to 100°C
• RoHS compliance status

Substitution Categories:

Direct Substitute (Weidmüller 1948350000): Identical manufacturer, same series (Omnimate BL), matching core electrical and mechanical specifications with enhanced current ratings and wire gauge compatibility. Active product status ensures ongoing availability.

Similar Substitute (On Shore Technology OSTVM135551): Alternative manufacturer with matching position count, pitch, and termination principle. Differs in wire entry angle (180° vs. 90°), contact material composition, and housing color. Suitable where mechanical orientation permits straight-entry configuration.

Parameter Comparison

Engineering Selection Recommendations

Weidmüller 1948350000 (Recommended Primary Substitute): This part is the preferred direct replacement for the 1553810000. Both components share identical manufacturer lineage within the Omnimate BL series, matching mechanical form factor and electrical interface. The 1948350000 maintains active product status with higher current ratings (23A IEC, 20A UL) and expanded wire gauge compatibility (12-30 AWG, 0.2-4mm²), providing enhanced capability within the same physical envelope. RoHS compliance and UL94 V-0 flammability certification are maintained. Current inventory of 1087 units ensures supply continuity.

On Shore Technology OSTVM135551 (Alternative Substitute): This part provides functional equivalence where mechanical orientation permits straight-entry (180°) wire configuration instead of the 90° entry of the original. The OSTVM135551 maintains 13-position, 5.08mm pitch architecture with UL94 V-0 compliance and 20A UL current rating. Differences include pressure clip termination (versus clamping yoke), zinc contact finish (versus tin), and steel contact material (versus copper alloy). Operating temperature range extends to 105°C. This substitute is suitable for applications where wire entry angle is not a constraint and where contact material composition is compatible with system requirements. ROHS3 compliance is confirmed.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1948350000 be used as a direct drop-in replacement for the 1553810000?

A: Yes. Both parts share identical 13-position, 5.08mm pitch configuration, 90° wire entry orientation, and screw-clamping termination. The 1948350000 is mechanically and electrically compatible. The primary difference is enhanced current rating (23A IEC vs. 15A IEC) and expanded wire gauge range, which do not prevent substitution in applications designed for the original part.

Q: What is the key difference between the Weidmüller 1948350000 and the On Shore Technology OSTVM135551?

A: The primary mechanical difference is wire entry angle: the Weidmüller maintains 90° entry while the OSTVM135551 uses 180° straight entry. Secondary differences include termination mechanism (clamping yoke vs. pressure clip), contact material (copper alloy vs. steel), and contact finish (tin vs. zinc). Both maintain 13 positions at 5.08mm pitch and UL94 V-0 compliance.

Q: Is the OSTVM135551 suitable for applications requiring tin-plated contacts?

A: No. The OSTVM135551 uses zinc-plated steel contacts, not tin-plated copper alloy. If tin plating is a system requirement, the Weidmüller 1948350000 is the appropriate substitute.

Q: What wire gauges are supported by each substitute part?

A: The 1553810000 supports 12-26 AWG (0.2-2.5mm²). The 1948350000 expands this to 12-30 AWG (0.2-4mm²). The OSTVM135551 supports 12-22 AWG. Verify wire gauge compatibility with your application before selection.

Q: Are both substitute parts RoHS compliant?

A: Yes. The Weidmüller 1948350000 is RoHS Compliant. The On Shore Technology OSTVM135551 is ROHS3 Compliant. Both meet RoHS requirements.

Q: What is the operating temperature range for each part?

A: The 1553810000 and 1948350000 both operate from -50°C to 100°C. The OSTVM135551 operates from -30°C to 105°C. Select based on your application's temperature requirements.

Q: Why is the 1553810000 listed as obsolete?

A: The 1553810000 has been discontinued by Weidmüller. The 1948350000 is the active replacement within the same product family, offering equivalent functionality with enhanced specifications.
