Engineering Selection Recommendations

Weidmüller 1948240000 (Direct Substitute)

The 1948240000 is the primary equivalent for the obsolete 1552710000. Both parts are manufactured by Weidmüller within the Omnimate BL series. The 1948240000 maintains identical pitch (5.08mm), mounting configuration (90° free-hanging), and screw specifications (M2.5, 0.4-0.5 Nm torque). The substitute offers enhanced electrical ratings (23A IEC, 20A UL versus 15A IEC, 10A UL) and expanded wire gauge compatibility (12-30 AWG versus 12-26 AWG). Operating temperature range remains -50°C to 100°C. The 1948240000 is active in production with RoHS compliance and higher inventory availability (5093 pcs versus 1030 pcs). This part is suitable for direct replacement in applications where the original specifications are met or exceeded.

TE Connectivity 284047-2 (Similar Substitute)

The 284047-2 from TE Connectivity AMP Connectors maintains core compatibility: 2-position, 5.08mm pitch, 90° wire entry, free-hanging mounting, and UL94 V-0 flammability rating. Electrical ratings (15A UL, 300V UL) meet the original part requirements. Wire gauge range (12-30 AWG, 0.05-3mm²) accommodates the original specification. Operating temperature extends to 110°C maximum. Differences include M3 screw size (versus M2.5), higher torque specification (0.79 Nm), phosphor bronze contact material (versus copper alloy), and polyamide housing (versus PBT). This part is suitable for applications where mechanical interface differences are accommodated.

On Shore Technology OSTVM025551 (Similar Substitute)

The OSTVM025551 provides functional equivalence with notable design differences. Core parameters align: 2-position, 5.08mm pitch, free-hanging mounting, UL94 V-0 rating, and 20A UL current rating. Wire gauge range (12-22 AWG) is narrower than the original. The primary distinction is 180° wire entry orientation (versus 90°), requiring different board layout accommodation. Contact material is steel with zinc finish (versus copper alloy with tin finish). Operating temperature range (-30°C to 105°C) is narrower than the original. This part is suitable only for applications where 180° wire entry orientation is acceptable and wire gauge requirements do not exceed 22 AWG.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1948240000 be used as a direct replacement for the 1552710000?

A: Yes. The 1948240000 is manufactured by the same company (Weidmüller) within the same series (Omnimate BL) and maintains identical pitch, mounting type, wire entry angle, and screw specifications. Electrical and temperature ratings meet or exceed the original part. The primary advantage is active production status and higher current capacity.

Q: What is the key difference between the TE Connectivity 284047-2 and the Weidmüller parts?

A: The 284047-2 uses M3 screws with 0.79 Nm torque (versus M2.5 with 0.4-0.5 Nm), phosphor bronze contacts with tin finish (versus copper alloy), and polyamide housing (versus PBT). These differences require verification of mechanical fit and assembly procedures. Electrical and temperature ratings are compatible.

Q: Why does the OSTVM025551 have a different wire entry angle?

A: The OSTVM025551 features 180° wire entry (straight-in) versus the 90° configuration of the original part. This design difference reflects the manufacturer's product architecture. Selection of this part requires board layout compatibility with straight-in wire entry orientation.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 1948240000 is RoHS Compliant. The 284047-2 and OSTVM025551 are ROHS3 Compliant. All parts meet regulatory requirements for lead-free and restricted substance compliance.

Q: What wire gauge limitations apply to each substitute?

A: The 1552710000 original part accommodates 12-26 AWG. The 1948240000 expands this to 12-30 AWG. The 284047-2 also supports 12-30 AWG. The OSTVM025551 is limited to 12-22 AWG. Applications requiring wire gauges larger than 22 AWG should use the 1948240000 or 284047-2.

Q: Which substitute has the highest current rating?

A: The Weidmüller 1948240000 provides the highest ratings: 23A IEC and 20A UL, compared to 15A IEC and 10A UL for the original part. This makes it suitable for higher-power applications within the same form factor.

Q: What packaging options are available for these parts?

A: The 1552710000 original part has no specified packaging. The 1948240000 is supplied in boxes. The 284047-2 is supplied in bulk. The OSTVM025551 is supplied in bulk. Packaging selection depends on inventory management and assembly requirements.
