Engineering Selection Recommendations

All identified substitute parts maintain the core functional specifications of the 2-282832-3 terminal block header. Selection among active alternatives should prioritize product status and regulatory compliance.

Primary Substitutes (Recommended for New Designs):

The A-TB500-OP22 (Assmann WSW Components) and ESZH22160 (Amphenol PCD) are active products with full compliance documentation. The A-TB500-OP22 carries ROHS3 compliance and REACH Unaffected status with extended operating temperature range (-40°C to 115°C). The ESZH22160 provides RoHS compliance with tin contact mating finish and UL94 V-0 flammability rating equivalent to the original part.

Secondary Substitutes (Alternative Options):

The OSTOP220000, OSTOP220100, and OSTOP220200 from On Shore Technology Inc. are active products with ROHS3 compliance and REACH Unaffected status. These parts differ in contact tail length and insulation height specifications. The OSTOP220000 and OSTOP220200 maintain the 0.138" (3.50mm) contact tail length of the original part, while OSTOP220100 features an extended 0.169" (4.29mm) contact tail length. Insulation height varies between 0.079" (2.00mm) and 0.138" (3.50mm) across the OSTOP series variants.

Frequently Asked Questions (FAQ)

Q: Can the A-TB500-OP22 directly replace the 2-282832-3 in existing applications?

A: The A-TB500-OP22 maintains electrical and mechanical compatibility with the 2-282832-3 across all critical parameters: 22 positions, 5.00mm pitch, vertical orientation, and through-hole solder mounting. The A-TB500-OP22 operates at 10 A UL current rating compared to the original 12 A rating. Verify application current requirements before substitution.

Q: What is the difference between the OSTOP220000, OSTOP220100, and OSTOP220200 variants?

A: The three On Shore Technology OSTOP variants differ in contact tail length and insulation height. OSTOP220000 and OSTOP220200 feature 0.138" (3.50mm) contact tail length matching the original part, while OSTOP220100 has an extended 0.169" (4.29mm) contact tail length. Insulation heights are 0.079" (2.00mm) for OSTOP220000 and OSTOP220100, and 0.138" (3.50mm) for OSTOP220200. Select the variant matching your PCB layout requirements.

Q: Are all substitute parts RoHS compliant?

A: The A-TB500-OP22, ESZH22160, OSTOP220000, OSTOP220100, and OSTOP220200 all carry RoHS compliance certifications. The A-TB500-OP22, OSTOP220000, OSTOP220100, and OSTOP220200 are ROHS3 compliant. The ESZH22160 is RoHS compliant. The original 2-282832-3 has RoHS status listed as not applicable.

Q: What packaging options are available for substitute parts?

A: The A-TB500-OP22 is supplied in bulk packaging. The ESZH22160 is supplied in tray packaging. The OSTOP220000, OSTOP220100, and OSTOP220200 are supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the ESZH22160 provide equivalent electrical performance to the 2-282832-3?

A: The ESZH22160 maintains the same 12 A UL current rating and 300 V UL voltage rating as the 2-282832-3. Both parts feature tin contact mating finish and operate across the -40°C to 110°C temperature range. The ESZH22160 uses copper alloy contacts compared to the brass contacts in the original part, with equivalent electrical performance.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are provided for reference: 2-282832-3 (765 pcs), A-TB500-OP22 (694 pcs), ESZH22160 (868 pcs), OSTOP220000 (704 pcs), OSTOP220100 (1057 pcs), and OSTOP220200 (1076 pcs). Inventory availability may change; verify current stock status with your supplier.
