Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M20-8763142 is determined by the following critical parameters:

• Pitch and Position Configuration: Mating pitch of 0.100" (2.54mm), 62 positions arranged in 2 rows with 0.100" row spacing
• Connector Type and Contact Geometry: Male pin header with square contact shape, unshrouded configuration
• Mounting and Termination: Surface mount with solder termination and push-pull fastening
• Electrical Performance: 3A current rating per contact, 250V voltage rating minimum
• Environmental Compliance: UL94 V-0 flammability rating, RoHS3 compliance, MSL 1 (Unlimited)
• Material Specifications: Gold-plated mating contacts, tin-plated posts, polyamide insulation material

The substitute part GBC31DABN-M30 from Sullins Connector Solutions meets these core substitution criteria while offering active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The GBC31DABN-M30 from Sullins Connector Solutions is a direct functional equivalent to the obsolete M20-8763142. Selection between these parts should be based on the following factors:

Product Status: The M20-8763142 is obsolete, whereas GBC31DABN-M30 maintains active product status, ensuring long-term availability and manufacturing support.

Compliance and Certifications: Both parts meet identical regulatory requirements including UL94 V-0 flammability rating, RoHS3 compliance, and EAR99 export classification. Both carry MSL 1 (Unlimited) moisture sensitivity level.

Operating Environment: The GBC31DABN-M30 provides an extended operating temperature range of -65°C to 150°C compared to the M20-8763142 range of -40°C to 105°C, offering greater thermal margin for demanding applications.

Connector Configuration: Both parts feature identical pitch, position count, row configuration, and contact geometry. The primary design difference is the connector type designation (Cuttable vs. Breakaway), which does not affect electrical or mechanical compatibility for standard board-to-board applications.

Material Composition: The substitute uses PA9T nylon insulation versus PA6T in the original part. Both polyamide formulations meet UL94 V-0 requirements and are functionally equivalent for this application class.

Frequently Asked Questions (FAQ)

Q: Can GBC31DABN-M30 be used as a direct replacement for M20-8763142 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (62), row configuration (2 rows), contact type (male pin), and electrical ratings (3A per contact). The connectors are mechanically and electrically compatible for board-to-board interconnection applications.

Q: What is the difference between "Cuttable" and "Breakaway" connector types?

A: Both designations refer to headers that can be separated into smaller segments. The functional performance and mating characteristics are equivalent for standard applications. Verify specific mechanical requirements if custom segmentation is required.

Q: Does the extended operating temperature range of GBC31DABN-M30 affect compatibility?

A: No. The extended range (-65°C to 150°C versus -40°C to 105°C) represents an enhancement that maintains full backward compatibility. Applications operating within the original temperature specification will function identically.

Q: Are there any differences in contact material that affect performance?

A: The M20-8763142 uses brass contacts while GBC31DABN-M30 uses phosphor bronze. Both materials provide equivalent electrical conductivity and contact reliability for this connector class. Both feature identical gold plating on mating surfaces and tin plating on posts.

Q: What packaging considerations apply to these parts?

A: The M20-8763142 is supplied in standard packaging with 726 pieces in stock. The GBC31DABN-M30 is supplied in bulk packaging with 713 pieces available. Verify packaging requirements for your procurement process.

Q: Are both parts RoHS compliant?

A: Yes. Both M20-8763142 and GBC31DABN-M30 are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.
