Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1553310000 is determined by the following critical parameters:

Primary Compatibility Criteria:

• 8 positions with 0.200" (5.08mm) pitch (mechanical and electrical interface requirement)
• Female socket configuration (connector gender requirement)
• Free hanging (in-line) mounting type (form factor requirement)
• Screw termination style (wire connection method)
• UL94 V-0 flammability rating (safety compliance)

Acceptable Parameter Variations:

• Wire entry orientation: 90° (main part) or 180° (acceptable for in-line applications with different PCB layout)
• Current rating: Substitute parts with equal or higher current capacity are acceptable
• Voltage rating: Substitute parts with equal or higher voltage rating are acceptable
• Wire gauge range: Substitute parts with equal or broader wire gauge compatibility are acceptable
• Operating temperature range: Substitute parts with equal or broader temperature range are acceptable
• Contact material and housing material: Variations acceptable if electrical and mechanical specifications are met

Substitute Parts Identified:

1. 1948300000 (Weidmüller) - Direct manufacturer upgrade with enhanced current and wire gauge ratings
2. 284047-8 (TE Connectivity AMP Connectors) - Cross-manufacturer equivalent with different termination mechanism
3. OSTVM085581 (On Shore Technology Inc.) - Alternative with 180° wire entry orientation
4. OSTVM085551 (On Shore Technology Inc.) - Alternative with 180° wire entry orientation

Parameter Comparison

Engineering Selection Recommendations

1948300000 (Weidmüller) - Recommended Primary Substitute

This part is the direct manufacturer upgrade path. It maintains identical mechanical form factor (90° wire entry, same pitch and position count) and termination method. The part is active in production with enhanced electrical ratings (20A UL vs. 10A) and broader wire gauge compatibility (12-30 AWG vs. 12-26 AWG). Both parts carry RoHS compliance and UL94 V-0 flammability rating. This substitution requires no design modification.

284047-8 (TE Connectivity AMP Connectors) - Cross-Manufacturer Equivalent

This part maintains the 90° wire entry orientation and identical pitch/position configuration. The termination mechanism differs (rising cage clamp vs. clamping yoke), which may affect installation procedures but does not impact electrical performance. Current rating is 15A UL, intermediate between the main part and other substitutes. Operating temperature range extends to 110°C. This substitution is suitable for applications where cross-manufacturer sourcing is acceptable and installation procedures can be adapted.

OSTVM085581 and OSTVM085551 (On Shore Technology Inc.) - Alternative with Wire Entry Orientation Change

Both parts feature 180° wire entry orientation instead of 90°, requiring PCB layout modification. They provide 20A UL current rating and maintain the 8-position, 5.08mm pitch configuration. Wire gauge compatibility is narrower (12-22 AWG). These substitutions are applicable only when PCB redesign is feasible or when the 180° orientation aligns with existing system architecture.

Compliance and Certification Status

All substitute parts maintain UL94 V-0 flammability compliance. The main part and 1948300000 are RoHS Compliant; substitute parts 284047-8, OSTVM085581, and OSTVM085551 are ROHS3 Compliant. All parts carry EAR99 ECCN classification and HTSUS code 8536.90.4000.

Frequently Asked Questions (FAQ)

Q: Can I use 1948300000 as a direct replacement for 1553310000 without any modifications?

A: Yes. The 1948300000 maintains identical mechanical and electrical interface specifications, including 90° wire entry, 8 positions at 5.08mm pitch, and screw termination. No PCB or assembly modifications are required. The part is an active production item with enhanced current and wire gauge ratings.

Q: What is the key difference between the 90° wire entry (main part and 1948300000) and the 180° wire entry (OSTVM085581 and OSTVM085551)?

A: Wire entry angle determines the physical orientation of the connector relative to the PCB. 90° entry is perpendicular to the board surface; 180° entry is parallel. Selecting 180° variants requires PCB layout modification to accommodate the different connector orientation. The electrical performance and pin configuration remain identical.

Q: Are the On Shore Technology parts (OSTVM085581 and OSTVM085551) interchangeable with each other?

A: Both parts are mechanically and electrically identical. The only difference is housing color (gray for OSTVM085581, green for OSTVM085551). They are functionally interchangeable. Selection between them is based on color coding requirements or availability.

Q: What is the significance of the different termination styles (clamping yoke vs. rising cage clamp vs. pressure clip)?

A: Termination style describes the wire clamping mechanism. All three styles provide secure screw-based wire connection. The clamping yoke (main part and 1948300000) and rising cage clamp (284047-8) are mechanically different but electrically equivalent. Pressure clip (On Shore parts) is also electrically equivalent. Selection depends on assembly procedures and tooling compatibility.

Q: Can I use a substitute part with a higher current rating than the original specification?

A: Yes. Substitute parts with equal or higher current ratings are acceptable. The 1948300000 (20A UL), 284047-8 (15A UL), OSTVM085581, and OSTVM085551 (both 20A UL) all meet or exceed the original 10A UL specification. Higher current ratings provide design margin and do not create compatibility issues.

Q: What wire gauge ranges are supported by each substitute part?

A: The main part supports 12-26 AWG (0.2-2.5mm²). The 1948300000 supports 12-30 AWG (0.2-4mm²), offering broader compatibility. The 284047-8 supports 12-30 AWG (0.05-3mm²). The On Shore parts (OSTVM085581 and OSTVM085551) support 12-22 AWG, which is narrower than the original specification. Verify wire gauge compatibility with your application requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part and 1948300000 are RoHS Compliant. The substitute parts 284047-8, OSTVM085581, and OSTVM085551 are ROHS3 Compliant. Both compliance levels are acceptable for RoHS-regulated applications.

Q: What is the packaging difference between these parts?

A: The main part 1553310000 has unspecified packaging. The 1948300000 is supplied in box packaging. The 284047-8, OSTVM085581, and OSTVM085551 are supplied in bulk packaging. Packaging affects order quantities and handling but does not impact component performance.
