Engineering Selection Recommendations

Primary Recommendation – Molex 0702464401

The Molex 0702464401 is the direct series equivalent within the C-Grid 70246 family. It maintains identical electrical and mechanical specifications to the obsolete 0702464421 while offering active product status and ROHS3 compliance. The primary difference is the post finish specification (tin versus tin-lead) and glass-filled PBT insulation material. This part is the preferred choice for direct replacement in existing designs with minimal qualification effort.

Secondary Recommendation – Sullins SBH11-PBPC-D22-ST-BK

The Sullins SBH11-PBPC-D22-ST-BK offers the highest compliance profile with ROHS3 certification and REACH unaffected status. It provides specified operating temperature range (-40°C to 105°C) and current rating (3A per contact), making it suitable for applications requiring documented electrical performance. The brass contact material and gold post finish provide enhanced durability. This part is recommended for new designs or applications with stringent compliance requirements.

Tertiary Recommendation – TE Connectivity 3-1761603-4

The TE Connectivity 3-1761603-4 from the AMP-Latch series provides active product status with ROHS3 compliance and specified electrical ratings (1A per contact, 250VAC). Operating temperature range is -65°C to 105°C. This part is suitable for applications requiring documented electrical performance specifications. Note the blue insulation color and slightly different contact post length (0.102" versus 0.135").

Alternative Options – Amphenol ICC (FCI) Quickie™ Series

The Amphenol ICC (FCI) Quickie™ series parts (66506-242, 66506-242LF, 66506-246, 66506-246LF) provide active product status with varying compliance certifications. Parts designated with "LF" suffix offer RoHS compliance. The 66506-246 and 66506-246LF variants feature longer contact post length (0.150" versus 0.135"), which may require mechanical verification for board clearance. These parts are suitable for applications where Amphenol ICC supply chain preference is established.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0702464421 be directly replaced with the Molex 0702464401?

A: Yes. Both parts are within the C-Grid 70246 series and maintain identical pitch, position count, shrouding, and fastening specifications. The primary differences are post finish (tin versus tin-lead) and insulation material composition (glass-filled PBT). These differences do not affect mechanical or electrical compatibility in standard applications.

Q: What are the key differences between the Amphenol ICC Quickie™ variants?

A: The 66506-242 and 66506-246 variants differ in contact post length: 0.105" (2.67mm) for the 242 series and 0.150" (3.81mm) for the 246 series. The "LF" suffix indicates lead-free compliance. Contact mating length is 0.230" (5.84mm) for both variants. Selection depends on board thickness and clearance requirements.

Q: Does the Sullins SBH11-PBPC-D22-ST-BK have different mechanical dimensions?

A: The Sullins part maintains the same pitch and position count but has a slightly different insulation height (0.358" versus 0.365") and contact post length (0.118" versus 0.135"). Mated stacking heights are specified as 9.65mm, 11.2mm, 13.35mm, and 18.35mm. Mechanical verification is required if board layout is space-constrained.

Q: What is the significance of the "LF" designation in Amphenol ICC part numbers?

A: The "LF" suffix indicates lead-free compliance, typically associated with RoHS certification. Parts 66506-242LF and 66506-246LF are RoHS compliant, while 66506-242 and 66506-246 are RoHS non-compliant. Selection depends on regulatory requirements for the end application.

Q: Are all substitute parts compatible with the same mating connectors?

A: All substitute parts maintain the 0.100" (2.54mm) pitch and 2-row configuration, ensuring compatibility with standard 2.54mm pitch receptacles. However, contact post length variations (0.102" to 0.150") may affect insertion force and mating reliability depending on receptacle design. Mechanical compatibility testing is recommended for critical applications.

Q: What packaging options are available?

A: The Molex 0702464401 is supplied in bulk packaging. Amphenol ICC Quickie™ series and Sullins SBH11 parts are supplied in tray packaging. Packaging selection may affect handling, storage, and cost considerations for high-volume production.

Q: Which substitute part offers the best compliance profile?

A: The Sullins SBH11-PBPC-D22-ST-BK offers ROHS3 compliance and REACH unaffected status. The Molex 0702464401 and TE Connectivity 3-1761603-4 both offer ROHS3 compliance. Amphenol ICC parts 66506-242LF and 66506-246LF offer RoHS compliance with REACH affected status. Selection depends on specific regulatory requirements.
