M20-8763442 Equivalent & Substitute Parts

Part Overview

The M20-8763442 is a rectangular connector header manufactured by Harwin Inc., designed for surface mount applications with 68 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The cuttable header configuration with unshrouded design and push-pull fastening supports board-to-board or cable interconnection in applications requiring high-density connections.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M20-8763442 is determined by strict alignment of the following critical parameters:

• Connector Type: Header configuration (cuttable vs. breakaway variants acceptable)
• Contact Type: Male Pin
• Number of Positions: 68
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Current Rating: 3A minimum per contact
• Voltage Rating: 250V minimum
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The GBC34DABN-M30 from Sullins Connector Solutions meets all substitution criteria. While the connector type differs (breakaway vs. cuttable), both configurations provide equivalent functional performance for board-to-board or cable applications. The substitute maintains identical electrical specifications, pitch geometry, and compliance certifications required for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

The GBC34DABN-M30 is a direct functional substitute for the obsolete M20-8763442. Selection is supported by the following factors:

• Both components maintain identical electrical and mechanical specifications for mating pitch, row spacing, contact count, and current/voltage ratings
• The substitute is in active production status, ensuring long-term availability and supply chain continuity
• Both components carry ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements
• The substitute's extended operating temperature range (-65°C ~ 150°C) provides additional thermal margin beyond the original specification (-40°C ~ 105°C)
• Surface mount termination and solder attachment methods are identical, requiring no PCB redesign

Frequently Asked Questions (FAQ)

Q: Can the GBC34DABN-M30 be used as a direct replacement without PCB modification?

A: Yes. Both components share identical mating pitch (0.100"), row spacing (0.100"), number of positions (68), and surface mount solder termination. PCB footprints are compatible.

Q: What is the difference between "cuttable" and "breakaway" header configurations?

A: Cuttable headers allow individual pins to be separated by cutting. Breakaway headers feature pre-scored sections for pin removal. Both configurations provide equivalent electrical performance and mating characteristics for board-to-board applications.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both components are ROHS3 compliant and carry UL94 V-0 flammability ratings. Regulatory compliance is equivalent.

Q: Does the substitute support the same current and voltage specifications?

A: Yes. The GBC34DABN-M30 maintains the 3A per contact current rating and meets the 250V voltage requirement of the original M20-8763442.

Q: What is the inventory status of the substitute part?

A: The GBC34DABN-M30 is in active production with 957 pieces available in stock as new original inventory.
