Molex 0702800726 Equivalent & Substitute Parts

Part Overview

The Molex 0702800726 is a rectangular connector header designed for through-hole mounting applications. This connector features 36 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, suitable for board-to-board or cable interconnections. The part is currently active in production with 1083 units in stock. Substitute parts may be required due to application-specific mounting constraints, such as surface mount requirements, or to accommodate design revisions that necessitate alternative connector configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0702800726 is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly
• Number of Rows: 2 — must match exactly
• Row Spacing - Mating: 0.100" (2.54mm) — must match exactly
• Contact Type: Male Pin — must match exactly
• Connector Type: Header, Breakaway — must match exactly
• Termination: Solder — must match exactly
• Material Flammability Rating: UL94 V-0 — must match exactly
• RoHS Status: ROHS3 Compliant — must match exactly
• Moisture Sensitivity Level (MSL): 1 (Unlimited) — must match exactly

The substitute parts GBC36DFBN-M30 and GEC36DFBN-M30 satisfy these critical parameters. However, these substitutes differ in mounting type (Surface Mount versus Through Hole) and position count (72 positions versus 36 positions). These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both GBC36DFBN-M30 and GEC36DFBN-M30 are active products with ROHS3 compliance and UL94 V-0 flammability ratings, matching the regulatory and safety requirements of the Molex 0702800726. All three parts maintain MSL 1 (Unlimited) moisture sensitivity classification.

The primary distinction between the substitute parts lies in contact finish: GBC36DFBN-M30 features gold mating contact finish, while GEC36DFBN-M30 uses tin finish. Both substitutes employ phosphor bronze contact material and polyamide insulation, differing from the original part's copper alloy and LCP insulation composition.

The substitutes are surface mount variants with 72 positions, compared to the through-hole 36-position configuration of the original part. Selection between these alternatives depends on PCB assembly method and circuit layout requirements.

Frequently Asked Questions (FAQ)

Q: Can GBC36DFBN-M30 or GEC36DFBN-M30 directly replace the Molex 0702800726 in existing designs?

A: Direct replacement is not possible without PCB redesign. The original part is through-hole mounted with 36 positions, while the substitutes are surface mount with 72 positions. Mounting type and position count differences require circuit layout modifications.

Q: What is the difference between GBC36DFBN-M30 and GEC36DFBN-M30?

A: Both parts are identical except for contact finish. GBC36DFBN-M30 has gold mating contact finish (10.0µin thickness), while GEC36DFBN-M30 has tin mating contact finish (100.0µin thickness). Contact material is phosphor bronze for both.

Q: Do the substitute parts meet the same compliance standards as the original?

A: Yes. All three parts are ROHS3 compliant, UL94 V-0 rated, and maintain MSL 1 (Unlimited) classification. Regulatory and safety compliance is equivalent.

Q: What is the pitch spacing for all three connectors?

A: All three parts maintain 0.100" (2.54mm) pitch spacing for both mating and row spacing, ensuring compatibility with standard 0.1-inch grid layouts.

Q: Are there inventory considerations for these parts?

A: GEC36DFBN-M30 has the highest inventory at 2865 units, followed by GBC36DFBN-M30 at 1547 units, and the original Molex part at 1083 units. All are in active production.
