Engineering Selection Recommendations

Direct Equivalent (Preferred for Drop-In Replacement):

The TE Connectivity 1-1546931-8 is the primary direct equivalent to the obsolete 1-282832-9. Both parts are manufactured by TE Connectivity AMP Connectors within the Buchanan series, maintain identical electrical ratings (12 A at 300 V), and share the same mechanical interface specifications including 18 positions, 5.00mm pitch, 0.138" contact tail length, and 0.079" insulation height. The 1-1546931-8 is active in production with RoHS compliance certification and 813 units in current inventory. The only notable difference is housing color (black versus green), which does not affect electrical or mechanical function.

Secondary Equivalents (Compatible with Minor Considerations):

The Amphenol PCD ESZH18160 provides full electrical and mechanical compatibility with identical 12 A current rating and matching dimensional specifications. This part is active, RoHS compliant, and available in high inventory (1047 units). The ESZH18160 uses copper alloy contacts instead of brass and does not specify a flammability rating, but maintains all critical interface parameters.

The Assmann WSW Components A-TB500-OP18 is compatible for applications where 10 A current rating is acceptable. This part meets all mechanical interface requirements and operates across an extended temperature range (-40°C to 115°C). It is active and ROHS3 compliant with 668 units in inventory.

Conditional Substitutes (Dimensional Variations):

The On Shore Technology OSTOP series parts (OSTOP180000, OSTOP180100, OSTOP180200) maintain the core 18-position, 5.00mm pitch vertical header configuration but exhibit variations in insulation height and contact tail length. OSTOP180000 and OSTOP180200 feature 0.138" insulation height matching the main part, while OSTOP180100 specifies 0.169" contact tail length. These parts are ROHS3 compliant and active in production but lack specified current ratings and flammability certifications. Use these substitutes only when dimensional variations do not conflict with PCB layout or connector mating requirements.

Compliance and Certification Status:

All active substitute parts maintain MSL 1 (unlimited moisture sensitivity) and ECCN EAR99 classification matching the original part. The TE Connectivity 1-1546931-8 and Amphenol PCD ESZH18160 provide the highest compliance assurance with explicit RoHS certification. On Shore Technology OSTOP series parts carry ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1546931-8 be used as a direct replacement for the obsolete 1-282832-9?

A: Yes. The 1-1546931-8 is a direct equivalent manufactured by the same company (TE Connectivity AMP Connectors) with identical electrical ratings (12 A, 300 V), mechanical configuration (18 positions, 5.00mm pitch, vertical orientation), and interface dimensions (0.138" contact tail, 0.079" insulation height). The housing color differs (black versus green), but this does not affect electrical or mechanical function. This is the recommended replacement.

Q: What is the difference between the TE Connectivity 1-1546931-8 and the Amphenol PCD ESZH18160?

A: Both parts are electrically and mechanically equivalent with 12 A current rating, 300 V voltage rating, and identical dimensional specifications. The primary differences are manufacturer (TE Connectivity versus Amphenol PCD), contact material (brass versus copper alloy), and housing material composition. The ESZH18160 does not specify a flammability rating. Both are active, RoHS compliant, and suitable for drop-in replacement.

Q: Can the Assmann WSW Components A-TB500-OP18 be substituted for the 1-282832-9?

A: The A-TB500-OP18 is mechanically compatible and meets all dimensional interface requirements. However, it is rated for 10 A current versus the original 12 A specification. This part is suitable for applications where the 10 A rating is acceptable. The A-TB500-OP18 operates across an extended temperature range (-40°C to 115°C) and is ROHS3 compliant.

Q: What are the dimensional differences in the On Shore Technology OSTOP series parts?

A: The OSTOP series maintains the core 18-position, 5.00mm pitch vertical header configuration but varies in two dimensions. OSTOP180000 and OSTOP180200 feature 0.138" insulation height matching the original part. OSTOP180100 specifies a longer contact tail of 0.169" (versus 0.138"). OSTOP180000 and OSTOP180200 feature 0.138" insulation height, while OSTOP180100 and OSTOP180200 feature 0.138" and 0.138" insulation heights respectively. Verify PCB layout compatibility before selection.

Q: Are all substitute parts RoHS compliant?

A: The TE Connectivity 1-1546931-8, Amphenol PCD ESZH18160, and all On Shore Technology OSTOP series parts carry RoHS or ROHS3 compliance certification. The Assmann WSW Components A-TB500-OP18 is ROHS3 compliant. The original 1-282832-9 does not specify RoHS status. All parts maintain MSL 1 (unlimited moisture sensitivity).

Q: What packaging options are available for these substitute parts?

A: The TE Connectivity 1-1546931-8 is supplied in bulk packaging. The Amphenol PCD ESZH18160 is supplied in tray packaging. The Assmann WSW Components A-TB500-OP18 and all On Shore Technology OSTOP series parts are supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Can these parts be used interchangeably in the same PCB design?

A: The TE Connectivity 1-1546931-8 and Amphenol PCD ESZH18160 are fully interchangeable with identical dimensional specifications. The Assmann WSW Components A-TB500-OP18 is mechanically interchangeable but operates at 10 A versus 12 A. The On Shore Technology OSTOP series parts require dimensional verification due to variations in insulation height and contact tail length. Confirm PCB footprint and connector mating requirements before final selection.

Q: What is the current inventory status for these parts?

A: TE Connectivity 1-1546931-8: 813 units. Assmann WSW Components A-TB500-OP18: 668 units. Amphenol PCD ESZH18160: 1047 units. On Shore Technology OSTOP180000: 754 units. On Shore Technology OSTOP180100: 836 units. On Shore Technology OSTOP180200: 1034 units. The original 1-282832-9 (obsolete) has 1070 units in stock.
