Molex 0010977366 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0010977366 is a through-hole rectangular connector header with 36 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This C-Grid 70280 series component features male pins with gold-plated mating contacts and tin-plated posts, designed for board-to-board or cable applications. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, particularly when mounting technology or position count variations are acceptable within system design constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0010977366 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
• Fastening Type: Push-Pull - must match exactly
• Contact Shape: Square - must match exactly
• Insulation Material: Liquid Crystal Polymer (LCP), Glass Filled or equivalent - must match exactly
• Material Flammability Rating: UL94 V-0 - must match exactly
• RoHS Status: ROHS3 Compliant - must match exactly

The substitute parts GBC36DFBN-M30 and GEC36DFBN-M30 share identical pitch, row configuration, contact type, and electrical characteristics. However, these substitutes differ in mounting technology (Surface Mount versus Through Hole) and position count (72 positions versus 36 positions). These differences represent design trade-offs that may be acceptable depending on application requirements and PCB layout constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with full RoHS3 compliance and REACH Unaffected designation, ensuring regulatory alignment across applications. The Molex 0010977366 is optimized for through-hole PCB assembly with 36-position configuration. The Sullins GBC36DFBN-M30 and GEC36DFBN-M30 are surface-mount alternatives with 72-position capacity, suitable for applications requiring higher connector density or surface-mount assembly processes.

Selection between the Molex original and Sullins substitutes depends on PCB assembly technology and position requirements. The GBC36DFBN-M30 features gold-plated mating contacts matching the Molex specification, while the GEC36DFBN-M30 uses tin-plated mating contacts. Both Sullins parts specify operating temperature range (-65°C ~ 150°C) and current rating (3A) not provided in the Molex datasheet excerpt. Contact material differences (Copper Alloy versus Phosphor Bronze) and insulation material variations (LCP Glass Filled versus Polyamide Nylon 9T) represent material engineering trade-offs between the manufacturers.

Frequently Asked Questions (FAQ)

Q: Can the Sullins GBC36DFBN-M30 or GEC36DFBN-M30 directly replace the Molex 0010977366 in a through-hole application?

A: No. The Molex 0010977366 is designed for through-hole mounting, while both Sullins substitutes are surface-mount components. Direct PCB footprint compatibility is not possible without redesign of the mounting interface.

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

A: The GBC36DFBN-M30 features gold-plated mating contacts, while the GEC36DFBN-M30 uses tin-plated mating contacts. Both maintain identical pitch, row spacing, and electrical characteristics.

Q: Why do the Sullins parts have 72 positions instead of 36?

A: The 72-position configuration represents a higher-density connector option within the same 2.54mm pitch family. Applications requiring additional signal or power connections can utilize the expanded position count.

Q: Are all three parts compliant with the same regulatory standards?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry UL94 V-0 material flammability ratings. Moisture sensitivity level is 1 (Unlimited) for all parts.

Q: What contact material differences exist between the parts?

A: The Molex 0010977366 uses Copper Alloy contacts, while both Sullins substitutes use Phosphor Bronze. Both materials are suitable for solder termination and push-pull fastening applications.

Q: Do the Sullins parts specify electrical ratings not provided for the Molex part?

A: Yes. The Sullins GBC36DFBN-M30 and GEC36DFBN-M30 specify operating temperature range (-65°C ~ 150°C) and current rating (3A). The Molex datasheet excerpt does not include these specifications.
