Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1557710000 is determined by the following critical parameters:

Core Compatibility Requirements:

6-position configuration with 0.200" (5.08mm) pitch spacing
Female socket type with free-hanging (in-line) mounting
Screw termination method
UL94 V-0 flammability rating
RoHS compliance status

Electrical Performance Boundaries:

Minimum current rating: UL 10A (IEC 15A baseline)
Minimum voltage rating: UL 300V (IEC 400V baseline)
Wire gauge accommodation: minimum 12 AWG support required

Mechanical Compatibility:

Retention latches on non-wire side
Operating temperature range overlap: -50°C minimum and 100°C maximum
Screw-based clamping mechanism

The substitute parts listed below meet these core requirements while accommodating variations in wire entry angle (270° vs. 180°), contact materials, housing materials, and screw specifications. These variations do not prevent functional substitution in applications where the main part is no longer available.

Engineering Selection Recommendations

Weidmüller 1949060000 (Direct Substitute)

The 1949060000 is the primary equivalent for the obsolete 1557710000. Both components share identical pitch, wire entry angle (270°), termination method (screw clamping yoke), and operating temperature range. The 1949060000 maintains active product status and provides enhanced electrical performance (20A UL vs. 10A UL) and expanded wire gauge accommodation (12-30 AWG vs. 12-26 AWG). RoHS compliance and UL94 V-0 flammability rating are maintained. This part is recommended for direct replacement in new designs and system upgrades.

TE Connectivity 284041-6 (Compatible Substitute)

The 284041-6 maintains 6-position, 5.08mm pitch configuration with 270° wire entry and free-hanging mounting. It meets UL94 V-0 and ROHS3 compliance requirements. Differences include rising cage clamp termination (vs. clamping yoke), M3 screw size (vs. M2.5), and expanded operating temperature range (-40°C ~ 110°C). Wire gauge support extends to 12-30 AWG. This part is suitable for applications where TE Connectivity components are preferred or where the enhanced temperature range is beneficial.

On Shore Technology OSTVM065551 (Compatible Substitute)

The OSTVM065551 provides 6-position, 5.08mm pitch connectivity with pressure clip termination and M2.5 screw specification matching the main part. Wire entry angle differs at 180° (vs. 270°), requiring mechanical layout verification. Wire gauge support is limited to 12-22 AWG. ROHS3 compliance and UL94 V-0 rating are maintained. This part is applicable where 180° wire entry orientation is acceptable and wire gauges remain within 12-22 AWG range.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1949060000 directly replace the 1557710000 in existing installations?

A: Yes. The 1949060000 is functionally equivalent with identical pitch (5.08mm), wire entry angle (270°), and termination method (screw clamping yoke). Both maintain UL94 V-0 and RoHS compliance. The 1949060000 provides equal or superior electrical performance and is the recommended direct replacement.

Q: What is the primary difference between the TE Connectivity 284041-6 and the Weidmüller parts?

A: The 284041-6 uses rising cage clamp termination instead of clamping yoke, requires M3 screws instead of M2.5, and offers an extended operating temperature range (-40°C ~ 110°C). The 5.08mm pitch and 270° wire entry remain compatible. Screw torque specifications differ (0.79 Nm vs. 0.4-0.5 Nm).

Q: Is the On Shore Technology OSTVM065551 suitable as a substitute if wire entry angle differs?

A: The OSTVM065551 features 180° wire entry instead of 270°. Substitution is possible only if the mechanical layout of your application can accommodate the different wire entry orientation. Wire gauge support is also more limited (12-22 AWG). Verify spatial constraints before selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Weidmüller 1949060000 is RoHS Compliant. The TE Connectivity 284041-6 and On Shore Technology OSTVM065551 are both ROHS3 Compliant. All parts meet current regulatory requirements.

Q: What wire gauge range should I verify when selecting a substitute?

A: The main part supports 12-26 AWG (0.2-2.5mm²). The 1949060000 accommodates 12-30 AWG (0.2-4mm²), the 284041-6 supports 12-30 AWG (0.05-3mm²), and the OSTVM065551 is limited to 12-22 AWG. Confirm your application's wire gauge falls within the substitute part's specified range.

Q: Do all substitute parts maintain the same current and voltage ratings?

A: No. The main part is rated 10A UL / 15A IEC at 300V UL / 400V IEC. The 1949060000 provides 20A UL at 300V UL. The 284041-6 provides 15A UL at 300V UL. The OSTVM065551 provides 20A UL at 300V UL. All meet or exceed the original specifications. Verify your application's current requirements do not exceed the substitute part's rating.

Q: What is the significance of the different screw sizes among these parts?

A: The main part and 1949060000 use M2.5 screws with 0.4-0.5 Nm torque specification. The 284041-6 uses M3 screws with 0.79 Nm torque. The OSTVM065551 uses M2.5 screws with 0.4 Nm torque. Screw size affects installation tooling and torque application. Verify your assembly process can accommodate the substitute part's screw specification.
