Molex 0702800686 Equivalent & Substitute Parts

Part Overview

The Molex 0702800686 is a vertical rectangular connector header with 36 positions at 2.54mm pitch, designed for through-hole board-to-board or cable applications. This connector is part of the C-Grid 70280 series and maintains active product status. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, design flexibility, or supply chain optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0702800686 is determined by strict alignment of the following critical parameters:

Core Electrical & Mechanical Compatibility Criteria:

Connector type: Header, Breakaway
Contact type: Male Pin
Pitch - mating: 0.100" (2.54mm)
Number of positions: 36
Number of rows: 2
Row spacing - mating: 0.100" (2.54mm)
Mounting type: Through Hole
Termination: Solder
Fastening type: Push-Pull
Contact shape: Square
Material flammability rating: UL94 V-0

Engineering Selection Recommendations

All four substitute parts maintain active product status and satisfy core substitution criteria based on connector type, contact configuration, pitch, position count, and mounting specifications.

Amphenol ICC 77313-101-36LF and 77313-818-36LF (BERGSTIK® Series): Both parts are ROHS3 compliant and provide operating temperature ranges of -65°C to 130°C. The 77313-101-36LF features a contact length post of 0.095" (2.41mm), while the 77313-818-36LF provides 0.120" (3.05mm). Contact finish thickness on the mating surface differs between the two: 77313-101-36LF maintains 30.0µin (0.76µm) matching the original specification, while 77313-818-36LF provides 15.0µin (0.38µm).

Sullins PBC18DAAN and PBC18DABN: Both parts are ROHS3 compliant with operating temperature ranges of -65°C to 125°C. The PBC18DAAN features a contact length post of 0.120" (3.05mm) and overall contact length of 0.450" (11.43mm). The PBC18DABN provides extended post length at 0.230" (5.84mm) with overall contact length of 0.560" (14.22mm). Both utilize Polybutylene Terephthalate (PBT) insulation material and carry MSL classification as Not Applicable.

Selection between substitute parts depends on specific board depth requirements and post length compatibility with mating connectors. All parts maintain UL94 V-0 flammability rating and black insulation color consistent with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 77313-101-36LF be used as a direct replacement for the Molex 0702800686?

A: Yes. Both parts share identical pitch (0.100" / 2.54mm), position count (36), row configuration (2 rows), and mounting type (through-hole solder). The 77313-101-36LF maintains the same mating contact finish thickness (30.0µin) as the original part. Differences in contact post length (0.095" vs. 0.175") and insulation material (thermoplastic vs. LCP) do not affect connector interface compatibility when mating with standard 2.54mm pitch receptacles.

Q: What is the difference between Amphenol ICC 77313-101-36LF and 77313-818-36LF?

A: Both are BERGSTIK® series headers with identical pitch, position count, and row spacing. Primary differences are contact post length (0.095" vs. 0.120") and mating contact finish thickness (30.0µin vs. 15.0µin). The 77313-818-36LF provides greater post length for applications requiring deeper board penetration. Both operate across -65°C to 130°C temperature range.

Q: How do the Sullins PBC18DAAN and PBC18DABN differ?

A: Both parts share identical pitch, position count, and row configuration. The primary distinction is contact post length: PBC18DAAN provides 0.120" (3.05mm) post length with 0.450" (11.43mm) overall contact length, while PBC18DABN extends to 0.230" (5.84mm) post length with 0.560" (14.22mm) overall contact length. Selection depends on board depth and mating connector requirements. Both operate across -65°C to 125°C and use PBT insulation material.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Amphenol ICC 77313-101-36LF is RoHS compliant. The Amphenol ICC 77313-818-36LF, Sullins PBC18DAAN, and Sullins PBC18DABN are all ROHS3 compliant. The original Molex 0702800686 is ROHS3 compliant.

Q: What is the difference in insulation material between the original part and substitutes?

A: The Molex 0702800686 uses Liquid Crystal Polymer (LCP) glass-filled insulation. Amphenol ICC parts use thermoplastic insulation. Sullins parts use Polybutylene Terephthalate (PBT) insulation. All materials maintain UL94 V-0 flammability rating and black color specification. Material selection does not affect electrical or mechanical interface compatibility.

Q: Do all parts support the same current rating?

A: The original Molex 0702800686 does not specify a current rating. All substitute parts are rated for 3A per contact (Amphenol ICC) or 3A total (Sullins). Verify application current requirements against the 3A specification when selecting substitutes.

Q: What is the operating temperature range for each part?

A: Molex 0702800686 does not specify operating temperature. Amphenol ICC 77313-101-36LF and 77313-818-36LF operate across -65°C to 130°C. Sullins PBC18DAAN and PBC18DABN operate across -65°C to 125°C. Select based on application temperature requirements.
