Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M20-8772142P is determined by the following critical parameters:

• Pitch and Position Count: 0.100" (2.54mm) pitch with 21 positions in a single row configuration
• Connector Type: Header format with male pin contact type
• Mounting Technology: Surface mount solder termination
• Electrical Performance: 3A per contact current rating
• Mechanical Compatibility: Unshrouded design with push-pull fastening
• Material and Compliance: UL94 V-0 flammability rating, ROHS3 compliance, and gold-plated mating contacts

The substitute part GBC21SABN-M30 meets these core substitution criteria while maintaining functional equivalence for the specified application requirements.

Parameter Comparison

Engineering Selection Recommendations

The GBC21SABN-M30 from Sullins Connector Solutions is the designated substitute for the obsolete M20-8772142P. Both components maintain identical pitch, position count, and electrical ratings. The substitute part is currently in active production status, ensuring supply chain continuity.

Key considerations for selection:

• Connector Breakaway Design: The GBC21SABN-M30 features a breakaway configuration compared to the cuttable design of the original part. Both designs provide equivalent functional performance for the specified application.
• Contact Material Variation: The substitute uses phosphor bronze contacts versus brass in the original. Both materials meet the 3A per contact current requirement and maintain gold plating on mating surfaces.
• Insulation Material Upgrade: The substitute employs PA9T nylon versus PA6T in the original, with an extended operating temperature range of -65°C to 150°C compared to -40°C to 105°C.
• Compliance Alignment: Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the GBC21SABN-M30 directly replace the M20-8772142P in existing designs?

A: Yes. Both parts share identical pitch (0.100"), position count (21), row configuration (1), mounting type (surface mount), termination method (solder), and current rating (3A per contact). The mating contact length difference of 0.002" (0.04mm) is within standard tolerance ranges for this connector category.

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

A: Cuttable headers allow individual positions to be separated by cutting the insulation strip. Breakaway headers feature pre-scored insulation allowing positions to be separated by hand or tool application. Both designs achieve equivalent functional connectivity for board-to-board applications.

Q: Does the contact material change from brass to phosphor bronze affect electrical performance?

A: No. Both materials provide equivalent electrical conductivity and current-carrying capacity at the 3A per contact rating. Phosphor bronze offers enhanced spring characteristics and wear resistance in mating cycles.

Q: Is the extended operating temperature range of the substitute part a concern?

A: No. The GBC21SABN-M30 operating range of -65°C to 150°C encompasses the original part's -40°C to 105°C specification. The substitute part maintains full performance within the original operating envelope.

Q: Are there packaging or inventory considerations?

A: The GBC21SABN-M30 is supplied in bulk packaging and maintains active production status with current inventory availability. The M20-8772142P is obsolete with limited remaining stock.
