Substitute Part Grouping Explanation
Substitution eligibility is determined by the following critical parameters:
- Connector Type: Receptacle, Bottom or Top Entry (required match)
- Number of Positions: 40 (required match)
- Pitch - Mating: 0.100" (2.54mm) (required match)
- Number of Rows: 2 (required match)
- Row Spacing - Mating: 0.100" (2.54mm) (required match)
- Mounting Type: Surface Mount (required match)
- Contact Type: Female Socket (required match)
- Fastening Type: Push-Pull (required match)
- Material Flammability Rating: UL94 V-0 (required match)
Substitute parts are grouped into two categories:
Category A: Amphenol ICC (FCI) Dubox™ Series Receptacles — Direct receptacle replacements with identical mechanical and electrical interfaces. These parts maintain the same connector type, position count, pitch, and fastening mechanism as the original 3M part.
Category B: Sullins Connector Solutions Headers — Header-type connectors with compatible pitch and position specifications. These parts differ in connector type (header vs. receptacle) but maintain electrical and mechanical compatibility through mating interface standards.

Engineering Selection Recommendations
Amphenol ICC (FCI) Dubox™ Series Receptacles (89898 and 91618 Base Numbers)
The Amphenol ICC receptacle options provide direct form-fit-function replacement for the obsolete 3M 963240-2000-AR-TP. All Dubox™ variants are active products with RoHS compliance certification. Selection between gold and tin contact finishes depends on application requirements:
- Gold-plated variants (89898-320ALF, 89898-320BLF, 89898-320LF, 91618-320LF): Suitable for applications requiring enhanced corrosion resistance and signal integrity.
- Tin-plated variants (89898-420LF, 91618-420LF): Appropriate for cost-sensitive applications where contact finish requirements are less stringent.
The 91618 series includes board lock features for enhanced mechanical retention. Packaging options (Tape & Reel, Tube, Box) accommodate different manufacturing workflows.
Sullins Connector Solutions Headers (NPPC202 and NPTC202 Base Numbers)
Header connectors from Sullins provide compatible pitch and position specifications with ROHS3 compliance. These parts are suitable for applications where header-type connectors are acceptable. Gold-plated headers (NPPC202KFMP-RC, NPPC202KFMS-RC) and tin-plated headers (NPTC202KFMP-RC, NPTC202KFMS-RC) are available. The NPTC202KFMS-RC variant offers the highest inventory availability (52,647 units).
Frequently Asked Questions (FAQ)
Q: Can Amphenol ICC Dubox™ receptacles directly replace the 3M 963240-2000-AR-TP?
A: Yes. The Dubox™ receptacles maintain identical connector type, position count, pitch, row spacing, mounting type, contact type, and fastening mechanism. All variants meet UL94 V-0 flammability requirements and are active products with current manufacturing support.
Q: What is the difference between gold and tin contact finishes?
A: Gold-plated contacts (30.0µin thickness) provide superior corrosion resistance and are preferred for high-reliability applications. Tin-plated contacts (78.7µin thickness) are suitable for general-purpose applications and offer cost advantages. Contact finish selection should align with application environmental conditions and signal integrity requirements.
Q: Can Sullins header connectors replace the 3M receptacle?
A: Sullins headers are compatible at the mating interface level due to matching pitch and position specifications. However, they differ in connector type (header vs. receptacle). System-level compatibility depends on whether the mating connector is a header or receptacle. Verify mating connector type before selection.
Q: What packaging options are available?
A: Amphenol ICC Dubox™ parts are available in Tape & Reel (89898-320ALF), Tube (89898-320BLF, 89898-420LF, 91618-320LF, 91618-420LF), and Box (89898-320LF) formats. Sullins headers are supplied in Tube packaging. Select packaging based on assembly process requirements and volume.
Q: Are all substitute parts RoHS compliant?
A: Yes. All Amphenol ICC Dubox™ variants are RoHS Compliant. All Sullins header variants are ROHS3 Compliant. The original 3M part does not specify RoHS status.
Q: What is the inventory status of substitute parts?
A: Amphenol ICC Dubox™ variants range from 896 to 1,173 units in stock. Sullins NPTC202KFMS-RC (tin-plated header) has the highest availability at 52,647 units. Verify current inventory with your supplier for procurement planning.
