Substitute Part Grouping Explanation

Substitution for the 963248-2000-AR-TP is determined by the following critical parameters:

Connector Type: Receptacle configuration (Bottom or Top Entry, Pass Through, or Header variants)
Position Count & Pitch: 48 positions at 0.100" (2.54mm) mating pitch with 2 rows at 0.100" row spacing
Mounting Method: Surface mount termination with solder attachment
Contact Finish: Gold-plated mating surface (primary specification) or tin-plated alternatives
Fastening Mechanism: Push-pull engagement system
Flammability Compliance: UL94 V-0 material rating
MSL Rating: Level 1 (Unlimited moisture sensitivity)

Substitute parts maintain these core electrical and mechanical parameters while allowing variations in insulation color, contact material composition, and packaging format. Connector type variations (receptacle vs. header) and contact finish options (gold vs. tin) represent distinct substitution categories based on application requirements.

Engineering Selection Recommendations

Primary Substitutes (Receptacle, Bottom or Top Entry Configuration)

The Amphenol ICC Dubox™ series (89898 and 91618 base part numbers) provides direct functional equivalence to the 963248-2000-AR-TP. These parts maintain identical connector type, position count, pitch, row spacing, mounting method, and fastening mechanism. All Amphenol ICC substitutes carry active product status with RoHS compliance and REACH compliance documentation, ensuring long-term availability and regulatory alignment.

Gold-plated contact finish substitutes include 89898-324ALF, 89898-324LF, and 91618-324LF. Tin-plated alternatives include 89898-424ALF, 89898-424LF, 91618-424LF, and 95242-424LF. Selection between gold and tin finishes depends on application corrosion resistance requirements and mating contact material specifications.

Secondary Substitutes (Header Configuration)

Sullins Connector Solutions NPPC242KFMP-RC (gold finish) and NPTC242KFMS-RC (tin finish) represent header connector alternatives. These parts maintain the same position count, pitch, row spacing, and surface mount termination. Header configuration differs from receptacle type, requiring board-level design accommodation. Operating temperature range extends to -40°C to 125°C, providing broader thermal coverage than the original part.

Alternative Substitute (Pass Through Receptacle)

Samtec Inc. SSM-124-F-DV (Tiger Claw™ SSM series) offers a pass-through receptacle configuration with gold-plated contacts. This part maintains core electrical parameters while providing extended operating temperature range (-55°C to 125°C) and higher current rating (5.2A per contact). Pass-through design enables cable or board-to-board connectivity options not available with standard receptacle types.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 963248-2000-AR-TP with any of the listed substitutes?

A: Direct replacement depends on connector type requirements. Amphenol ICC receptacle parts (89898 and 91618 series) provide direct form-fit-function equivalence. Sullins header connectors and Samtec pass-through receptacles require board-level design modifications due to connector type differences.

Q: What is the difference between gold and tin contact finishes?

A: Gold-plated contacts (30.0µin to flash thickness) provide superior corrosion resistance and lower contact resistance. Tin-plated contacts (78.7µin thickness) offer cost efficiency and adequate performance in non-corrosive environments. Selection depends on application environment and mating contact material compatibility.

Q: Are all substitutes RoHS compliant?

A: Amphenol ICC parts (89898, 91618, 95242 series) carry RoHS Compliant or ROHS3 Compliant status. Sullins parts (NPPC242, NPTC242 series) are ROHS3 Compliant. Samtec SSM-124-F-DV is ROHS3 Compliant. All substitutes meet current regulatory requirements.

Q: What packaging options are available?

A: Amphenol ICC parts are supplied in Bag, Tube, or Tape & Reel formats. Sullins and Samtec parts are supplied in Tube packaging. Packaging selection affects procurement logistics and automated assembly compatibility.

Q: How do insulation height variations affect compatibility?

A: The original part specifies 0.292" (7.41mm) insulation height. Amphenol ICC substitutes measure 0.275" (6.99mm), Sullins parts measure 0.299" (7.60mm), and Samtec measures 0.290" (7.37mm). These variations may affect mated stacking heights and board clearance requirements in constrained designs.

Q: What is the MSL rating and why does it matter?

A: All listed parts carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. This eliminates bake-out requirements and simplifies supply chain management.
