Substitute Part Grouping Explanation

Substitute parts for the Molex 0702800637 are qualified based on the following critical parameters that must align with the original specification:

Connector Type: Header, Breakaway configuration
Contact Type: Male Pin
Pitch - Mating: 0.100" (2.54mm) exact match
Number of Positions: 18 positions
Number of Rows: 2 rows
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole
Termination: Solder
Fastening Type: Push-Pull
Shrouding: Unshrouded
Material Flammability Rating: UL94 V-0

All identified substitute parts meet these core electrical and mechanical requirements. Variations in contact length, insulation material, contact finish thickness, and operating temperature ranges are secondary parameters that do not prevent substitution when the primary parameters align.

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and comply with UL94 V-0 flammability requirements. Selection among equivalent parts should be based on the following compliance considerations:

TE Connectivity 5-146256-9, Amphenol ICC 67997-218HLF, 77313-101-18LF, and 77313-118-18LF maintain RoHS compliance status consistent with regulatory requirements. The Amphenol ICC 77313-118-18LF carries REACH Affected status, whereas the 77313-101-18LF carries REACH Unaffected status. Both Amphenol ICC parts maintain REACH Unaffected or Affected designations as specified.

Sullins Connector Solutions parts (PBC09DAAN, PBC09DABN, PEC09DAAN) are ROHS3 Compliant and carry REACH Unaffected status, with Moisture Sensitivity Level classified as Not Applicable, indicating different handling requirements compared to the original Molex part.

All parts are classified under ECCN EAR99 and HTSUS 8536.69.4040, maintaining consistent export and tariff classifications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-146256-9 directly replace the Molex 0702800637?

A: Yes. Both parts share identical pitch (0.100" / 2.54mm), position count (18), row configuration (2 rows), connector type (Header, Breakaway), contact type (Male Pin), mounting type (Through Hole), termination (Solder), and fastening type (Push-Pull). Both maintain UL94 V-0 flammability rating and RoHS compliance.

Q: What is the difference between Amphenol ICC 67997-218HLF and 77313-101-18LF?

A: Both parts meet the core substitution parameters. The 67997-218HLF is classified as Header without breakaway designation, while 77313-101-18LF is Header with Breakaway. The 67997-218HLF operates at -65°C to 130°C with Phosphor Bronze contacts, while 77313-101-18LF operates at -65°C to 130°C with Phosphor Bronze contacts and higher contact finish thickness on mating surfaces (30.0µin vs. 15.0µin).

Q: Are Sullins parts suitable for applications requiring Moisture Sensitivity Level 1?

A: Sullins parts (PBC09DAAN, PBC09DABN, PEC09DAAN) are classified with Moisture Sensitivity Level as Not Applicable, indicating different moisture handling protocols compared to the original Molex part with MSL 1 (Unlimited). Applications with specific MSL requirements should confirm compatibility with Sullins handling specifications.

Q: What distinguishes PBC09DAAN from PBC09DABN?

A: Both parts are Sullins Connector Solutions headers with identical pitch, position count, and core electrical parameters. The primary difference is contact length post: PBC09DAAN has 0.120" (3.05mm) post length, while PBC09DABN has 0.230" (5.84mm) post length, resulting in overall contact lengths of 0.450" and 0.560" respectively.

Q: Can PEC09DAAN replace parts requiring gold-plated mating contacts?

A: No. PEC09DAAN features tin-plated mating contacts (100.0µin / 2.54µm thickness), whereas the Molex 0702800637 and most substitute parts feature gold-plated mating contacts. Applications requiring gold plating should select parts with gold contact finish specification.

Q: Are all substitute parts rated for 3A current?

A: The Molex 0702800637 does not specify a current rating. Substitute parts from TE Connectivity and Amphenol ICC specify 3A or 3A per contact ratings. Sullins parts specify 3A current rating. Applications with specific current requirements should confirm part selection against load specifications.
