Molex 0702800602 Equivalent & Substitute Parts

Part Overview

The Molex 0702800602 is a vertical rectangular connector header with 28 positions at 2.54mm pitch, designed for through-hole board-to-board or cable applications. This connector is classified as active product status with full inventory availability (1139 pcs). The C-Grid 70280 series header features unshrouded, breakaway design with solder termination and push-pull fastening. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or supply constraints exist.

Engineering Selection Recommendations

All four substitute parts maintain active product status and meet UL94 V-0 flammability requirements, ensuring compliance with the original specification. The Amphenol ICC 77313-801-28LF (BERGSTIK® series) offers the widest operating temperature range (-65°C to 130°C) and is RoHS compliant. The three Sullins alternatives (PBC14DAAN, PEC14DAAN, PEC14DACN) are ROHS3 compliant with operating ranges of -65°C to 125°C.

Contact length variations exist across all substitutes. The Amphenol ICC part features the shortest post length (0.095"), while the Sullins PEC14DACN provides the longest post length (0.320"). These dimensional differences may affect board layout compatibility and should be evaluated against specific application requirements. Contact finish specifications vary, with the Amphenol ICC part offering gold plating and the Sullins parts offering either gold or tin finishes. All parts maintain tin finish on the post contact.

Selection should prioritize inventory availability and operating temperature requirements specific to the application environment. All substitutes are electrically and mechanically compatible for standard board-to-board connector applications at 2.54mm pitch with 28-position, 2-row configuration.

Frequently Asked Questions (FAQ)

Q: What defines electrical and mechanical compatibility for the Molex 0702800602 substitutes?

A: Compatibility is determined by matching connector type (Header, Breakaway), contact type (Male Pin), pitch (0.100" / 2.54mm), position count (28), row configuration (2 rows), mounting method (Through Hole), termination type (Solder), and fastening mechanism (Push-Pull). All listed substitutes meet these core criteria.

Q: How do contact length variations affect substitution suitability?

A: Contact length differences (ranging from 0.425" to 0.650" overall length) may impact board thickness compatibility and mating depth. Applications with specific board thickness or connector depth constraints should verify that the substitute part's contact length accommodates the intended PCB stack-up and mating connector specifications.

Q: Are there compliance differences between the main part and substitutes?

A: The Molex 0702800602 is ROHS3 compliant with MSL 1 rating. The Amphenol ICC 77313-801-28LF is RoHS compliant (not explicitly ROHS3) with MSL 1 rating. The three Sullins parts are ROHS3 compliant with MSL Not Applicable. All parts meet UL94 V-0 flammability requirements. Compliance verification against specific application standards is recommended.

Q: What is the significance of contact finish differences?

A: The original Molex part specifies tin finish on mating contacts with 150.0µin thickness. Substitutes offer tin or gold finishes with varying thicknesses (10.0µin to 100.0µin). Gold-plated contacts (Amphenol ICC and Sullins PBC14DAAN) provide enhanced corrosion resistance, while tin-finished contacts (Sullins PEC14DAAN and PEC14DACN) offer cost efficiency. Contact finish selection should align with environmental exposure and reliability requirements.

Q: Can the Sullins PEC14DACN be used in applications requiring shorter post lengths?

A: The Sullins PEC14DACN features a 0.320" post length, the longest among all substitutes. This part is suitable for applications requiring extended post engagement or deeper board penetration. For applications with space constraints or shorter post requirements, the Amphenol ICC 77313-801-28LF (0.095" post) or Sullins PBC14DAAN and PEC14DAAN (0.120" post) are more appropriate selections.

Q: What operating temperature range should be considered for substitute selection?

A: The Amphenol ICC 77313-801-28LF operates from -65°C to 130°C, providing the widest temperature envelope. The three Sullins substitutes operate from -65°C to 125°C. The original Molex part does not specify an operating temperature range. Selection should be based on the application's thermal environment and any temperature-dependent performance requirements.
