Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M20-8763546 are identified based on the following critical parameters that determine functional equivalence:

• Number of Positions: 70
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Surface Mount
• Contact Type: Male Pin
• Termination: Solder
• Style: Board to Board or Cable
• Shrouding: Unshrouded
• Current Rating: 3A
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The substitute part GBC35DABN-M30 from Sullins Connector Solutions meets these core electrical and mechanical parameters, enabling direct functional replacement in applications requiring a 70-position, 2-row surface mount header connector with 2.54mm pitch.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can GBC35DABN-M30 be used as a direct replacement for M20-8763546?

A: Yes. Both connectors share identical mating pitch (2.54mm), position count (70), row configuration (2 rows), and current rating (3A). Surface mount termination and solder attachment methods are equivalent.

Q: What are the key differences between these parts?

A: The M20-8763546 features a cuttable header design with tin contact finish, while the GBC35DABN-M30 is a breakaway header with gold-plated mating contacts and phosphor bronze material. The substitute operates across a wider temperature range (-65°C to 150°C versus -40°C to 105°C). The M20-8763546 is obsolete; GBC35DABN-M30 is active production.

Q: Are there packaging differences?

A: The M20-8763546 is supplied in standard packaging, while GBC35DABN-M30 is supplied in bulk packaging. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: Do both parts meet current compliance standards?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the contact material difference?

A: M20-8763546 uses brass contacts with tin finish. GBC35DABN-M30 uses phosphor bronze contacts with gold mating finish and tin post finish. Both materials support the 3A current rating and 250V voltage specification.
