Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4-87543-0 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Number of Positions: 80
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Connector Type: Header
• Contact Type: Male Pin

Electrical & Material Parameters:

• Contact Material: Phosphor Bronze
• Insulation Material: Polyamide (PA), Nylon, Glass Filled
• Termination: Solder
• Fastening Type: Push-Pull

Environmental & Compliance Parameters:

• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8536.69.4040

The substitute part 9-87543-0 maintains full equivalence across all mechanical, electrical, and material specifications. The primary distinction is product status: 9-87543-0 is active and RoHS Compliant, whereas 4-87543-0 is obsolete with non-applicable RoHS status. Contact finish specifications differ minimally (Tin-Lead versus Tin), representing a material upgrade in the active substitute.

Parameter Comparison

Engineering Selection Recommendations

The 9-87543-0 serves as the direct active equivalent to the obsolete 4-87543-0. Both components share identical mechanical and electrical specifications within the AMPMODU Mod II series, ensuring functional interchangeability in through-hole applications requiring 80-position, 2-row rectangular connectors with 0.100" (2.54mm) pitch.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 4-87543-0 is classified as obsolete with non-applicable RoHS status, while the 9-87543-0 is an active product with RoHS Compliant certification. For new designs or ongoing production requiring regulatory compliance with current environmental standards, the 9-87543-0 is the appropriate selection.

Contact finish specifications differ between the two parts: the 4-87543-0 features Tin-Lead plating, while the 9-87543-0 uses Tin plating. Both maintain equivalent contact finish thickness of 100.0µin (2.54µm) on mating and post surfaces. This material upgrade in the active substitute aligns with contemporary manufacturing practices and environmental regulations.

Both parts maintain identical moisture sensitivity levels (MSL 1 - Unlimited), export classification (EAR99), and tariff codes (HTSUS 8536.69.4040), supporting seamless integration into existing supply chains and regulatory documentation.

Frequently Asked Questions (FAQ)

Q: Can the 9-87543-0 directly replace the 4-87543-0 in existing designs?

A: Yes. The 9-87543-0 maintains full mechanical and electrical equivalence to the 4-87543-0 across all critical parameters: 80 positions, 2 rows, 0.100" (2.54mm) pitch, through-hole mounting, solder termination, and push-pull fastening. Both components are unshrouded headers with identical contact materials, insulation specifications, and dimensional characteristics.

Q: What is the significance of the contact finish difference between these parts?

A: The 4-87543-0 uses Tin-Lead contact finish, while the 9-87543-0 uses Tin finish. Both maintain identical contact finish thickness of 100.0µin (2.54µm). The Tin finish in the 9-87543-0 represents a material upgrade aligned with current manufacturing standards and environmental compliance requirements. Contact finish thickness equivalence ensures consistent electrical performance and mating characteristics.

Q: Why is the 4-87543-0 listed as obsolete?

A: The 4-87543-0 has reached end-of-life status within TE Connectivity's product portfolio. The 9-87543-0 represents the active continuation of this connector family, offering identical functionality with current regulatory compliance and manufacturing support.

Q: Are there packaging differences between these parts?

A: The 4-87543-0 is supplied with unspecified packaging, while the 9-87543-0 is supplied in bulk packaging. Both parts maintain identical electrical and mechanical specifications. Packaging differences do not affect component functionality or interchangeability.

Q: What is the RoHS compliance status of these connectors?

A: The 4-87543-0 has non-applicable RoHS status due to its obsolete classification. The 9-87543-0 is RoHS Compliant, meeting current environmental and regulatory requirements for electronic components. For applications requiring RoHS compliance documentation, the 9-87543-0 is the appropriate selection.

Q: Are both parts classified under the same export and tariff categories?

A: Yes. Both the 4-87543-0 and 9-87543-0 share identical export classification (ECCN: EAR99) and tariff codes (HTSUS: 8536.69.4040), supporting consistent regulatory documentation and supply chain management.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage, handling, or assembly.
