Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 87543-6 connector is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (12)
• Number of rows (2)
• Pitch spacing (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Contact length specifications (Mating: 0.318", Post: 0.125", Overall: 0.533")
• Insulation height (0.090")
• Contact material (Phosphor Bronze)
• Insulation material (Polyamide/Nylon, Glass Filled)

The substitute parts 5-87543-6 and 87227-6 maintain full dimensional and functional compatibility with the original 87543-6 specification. Both alternatives are manufactured by TE Connectivity AMP Connectors and belong to the AMPMODU Mod II series. The primary distinction between substitutes relates to contact finish specifications and product status classification.

Parameter Comparison

Engineering Selection Recommendations

5-87543-6 Selection Criteria:

The 5-87543-6 connector is an active product offering direct functional equivalence to the obsolete 87543-6. This substitute maintains identical dimensional specifications, contact geometry, and insulation material composition. The primary distinction is the contact finish specification, which changes from Tin-Lead to Tin. Both finishes provide equivalent electrical performance and solder compatibility. The 5-87543-6 carries RoHS Compliant certification, aligning with current regulatory requirements. This part is recommended for applications where the original 87543-6 specification is required and RoHS compliance is mandatory.

87227-6 Selection Criteria:

The 87227-6 connector provides functional equivalence with notable material and finish variations. This substitute features a thermoplastic insulation material instead of polyamide/nylon glass-filled composition, and employs gold contact finish with flash thickness on the post. The 87227-6 includes additional specifications not present in the main part: operating temperature range of -65°C to 105°C, current rating of 3A, and UL94 V-0 flammability rating. The RoHS status is listed as not applicable, and REACH status is marked as affected. This part is suitable for applications requiring enhanced thermal performance, higher current capacity, or specific flammability certifications.

Compliance Considerations:

Selection between 5-87543-6 and 87227-6 depends on regulatory and performance requirements. For RoHS-compliant applications, 5-87543-6 is the appropriate choice. For applications requiring thermal specifications or flammability ratings, 87227-6 provides additional performance data. Both parts maintain full mechanical and electrical compatibility with the original 87543-6 specification.

Frequently Asked Questions (FAQ)

Q: Can 5-87543-6 be used as a direct replacement for 87543-6?

A: Yes. The 5-87543-6 maintains identical dimensional specifications, contact geometry, pitch spacing, and mounting characteristics as the 87543-6. The contact finish changes from Tin-Lead to Tin, which does not affect functional compatibility. Both finishes are compatible with standard solder processes.

Q: What is the primary difference between 5-87543-6 and 87227-6?

A: The primary differences are contact finish specification and insulation material. The 5-87543-6 uses Tin finish on Polyamide/Nylon glass-filled insulation, while 87227-6 uses Gold finish on Thermoplastic insulation. Additionally, 87227-6 includes operating temperature range (-65°C to 105°C), current rating (3A), and UL94 V-0 flammability rating specifications.

Q: Are all three connectors mechanically interchangeable?

A: Yes. All three connectors (87543-6, 5-87543-6, and 87227-6) share identical mechanical specifications including 12 positions, 2 rows, 0.100" pitch spacing, through-hole mounting, and solder termination. They are mechanically interchangeable in board-level applications.

Q: Which substitute should be selected for new designs?

A: For new designs requiring RoHS compliance, select 5-87543-6. For applications requiring thermal performance specifications or flammability ratings, select 87227-6. Both are active products with established supply chains.

Q: Does the contact finish change affect electrical performance?

A: No. Tin and Tin-Lead finishes provide equivalent electrical conductivity and contact resistance characteristics. Gold finish on 87227-6 offers enhanced corrosion resistance but is not required for standard applications.

Q: What is the packaging difference between the main part and substitutes?

A: The main part 87543-6 packaging is not specified in the provided data. Substitute 5-87543-6 is supplied in Bulk packaging. Substitute 87227-6 is supplied in Bulk packaging. Packaging format does not affect connector functionality.

Q: Are there any applications where 87227-6 cannot be used as a substitute?

A: The 87227-6 thermoplastic insulation material differs from the polyamide/nylon glass-filled material in the original 87543-6. Applications with specific material requirements should verify compatibility. The RoHS not applicable status may restrict use in regulated environments requiring RoHS compliance.

Q: What is the inventory status of each part?

A: The 87543-6 (obsolete) has 915 pieces in stock. The 5-87543-6 (active) has 659 pieces in stock. The 87227-6 (active) has 1178 pieces in stock. Inventory levels are subject to change.
