Engineering Selection Recommendations

Primary Substitutes (Full Compliance):

The Phoenix Contact 1935585 and Amphenol PCD ESZH20160 provide the closest functional equivalence to the TE Connectivity 2-282832-1. Both parts maintain identical pitch, position count, orientation, and mounting specifications. The Phoenix Contact 1935585 offers active product status with ROHS3 compliance and REACH unaffected certification. The Amphenol PCD ESZH20160 is supplied in tray packaging and carries RoHS compliance. Both parts support the 300 V UL voltage requirement and feature tin contact mating finish.

Secondary Substitutes (Parameter Variations):

The Assmann WSW A-TB500-OP20 meets all critical dimensional and electrical specifications with active product status and ROHS3 compliance. This part operates across an extended temperature range (-40°C to 115°C) and carries REACH unaffected certification. The UL current rating of 10 A is lower than the original 12 A specification.

The On Shore Technology OSTOP200000 and OSTOP200200 maintain dimensional compatibility with identical contact tail length (0.138" / 3.50mm) and insulation height (0.079" / 2.00mm) specifications. Both carry ROHS3 compliance and REACH unaffected status. The OSTOP200100 variant features an extended contact tail length of 0.169" (4.29mm), which may require board layout verification.

Compliance Considerations:

All active substitute parts carry ROHS3 compliance and MSL 1 moisture sensitivity rating. The Phoenix Contact 1935585 and Assmann WSW A-TB500-OP20 provide explicit REACH unaffected certification. The On Shore Technology variants (OSTOP200000, OSTOP200100, OSTOP200200) also carry REACH unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8536.69.4040.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1935585 directly replace the TE Connectivity 2-282832-1?

A: The Phoenix Contact 1935585 meets all critical specifications: 20 positions, 5.00mm pitch, vertical orientation, through-hole solder termination, 300 V UL rating, and identical contact tail and insulation dimensions. The part is active and carries ROHS3 compliance. Direct substitution is supported by dimensional and electrical parameter equivalence.

Q: What is the difference between the On Shore Technology OSTOP200000, OSTOP200100, and OSTOP200200 variants?

A: The primary differences are contact tail length and insulation height. The OSTOP200000 and OSTOP200200 both feature 0.138" (3.50mm) contact tail length. The OSTOP200000 has 0.138" (3.50mm) insulation height, while OSTOP200200 has 0.138" (3.50mm) insulation height. The OSTOP200100 features an extended contact tail length of 0.169" (4.29mm) with 0.079" (2.00mm) insulation height. Selection depends on specific board layout and mounting requirements.

Q: Does the Assmann WSW A-TB500-OP20 meet the current rating of the original part?

A: The Assmann WSW A-TB500-OP20 carries a UL current rating of 10 A, compared to the original 12 A specification. This represents a 2 A reduction in rated current capacity. Application requirements must be evaluated to determine if this lower rating is acceptable for the intended circuit.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts carry ROHS3 compliance. The Phoenix Contact 1935585, Assmann WSW A-TB500-OP20, and On Shore Technology variants (OSTOP200000, OSTOP200100, OSTOP200200) all meet ROHS3 requirements. The Amphenol PCD ESZH20160 carries RoHS compliance certification.

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

A: The Phoenix Contact 1935585 is supplied in bulk packaging. The Assmann WSW A-TB500-OP20 and On Shore Technology variants (OSTOP200000, OSTOP200100, OSTOP200200) are supplied in bulk packaging. The Amphenol PCD ESZH20160 is supplied in tray packaging. Packaging selection may affect procurement and handling procedures.

Q: Can the Amphenol PCD ESZH20160 be used in applications requiring UL94 V-0 flammability rating?

A: The Amphenol PCD ESZH20160 does not provide explicit UL94 V-0 flammability rating in the available specifications. Applications requiring UL94 V-0 certification should prioritize the Phoenix Contact 1935585 or Assmann WSW A-TB500-OP20, both of which carry this rating.

Q: What is the inventory status of these substitute parts?

A: Current inventory levels are: Phoenix Contact 1935585 (952 units), Assmann WSW A-TB500-OP20 (843 units), Amphenol PCD ESZH20160 (1007 units), On Shore Technology OSTOP200000 (774 units), OSTOP200100 (657 units), and OSTOP200200 (693 units). Inventory levels are subject to change and should be verified at time of procurement.
