Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M20-8772446P is determined by the following critical parameters:

• Pitch and Position Count: 0.100" (2.54mm) pitch with 24 positions in a single row configuration
• Connector Type: Header format with male pin contacts
• Mounting Technology: Surface mount (SMD) termination
• Electrical Rating: 3A per contact minimum
• Mechanical Interface: Push-pull fastening with unshrouded design
• Compliance: ROHS3 compliance and UL94 V-0 flammability rating
• Contact Material and Finish: Tin-plated contacts on brass or phosphor bronze base material

The substitute part GEC24SABN-M30 meets these core substitution criteria through equivalent pitch, position count, mounting type, electrical rating, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The GEC24SABN-M30 from Sullins Connector Solutions is a direct functional equivalent for the obsolete M20-8772446P. Both components share identical pitch, position count, mounting technology, electrical rating, and compliance certifications. The primary distinction lies in product status: the M20-8772446P is obsolete, while the GEC24SABN-M30 maintains active production status, ensuring long-term availability and supply chain continuity.

Material composition differences (phosphor bronze versus brass for contacts, PA9T versus PA6T for insulation) represent standard engineering variations within the rectangular connector category and do not affect functional compatibility. The GEC24SABN-M30 provides an extended operating temperature range (-65°C ~ 150°C versus -40°C ~ 105°C), offering additional thermal margin for demanding applications.

Both components carry ROHS3 compliance and UL94 V-0 flammability certification, meeting current regulatory requirements. The transition from cuttable to breakaway header configuration represents a minor mechanical variation that does not impact electrical or mating interface performance.

Frequently Asked Questions (FAQ)

Q: Can GEC24SABN-M30 directly replace M20-8772446P in existing designs?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (24), contact type (male pin), mounting method (surface mount), and electrical rating (3A per contact). The mating interface and PCB footprint are compatible.

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

A: Cuttable headers allow individual positions to be separated by cutting the connector body. Breakaway headers feature pre-scored sections for position separation. Both configurations provide equivalent electrical and mechanical performance in the final assembled state.

Q: Are the contact materials interchangeable?

A: Brass and phosphor bronze contacts are functionally equivalent for this connector category. Both materials provide adequate conductivity and durability for 3A per contact applications. Material selection does not affect mating performance or electrical characteristics.

Q: Does the insulation material change affect compatibility?

A: No. PA6T (Nylon 6T) and PA9T (Nylon 9T) are both polyamide-based insulation materials suitable for this connector class. The PA9T formulation in the substitute part offers equivalent or superior performance characteristics.

Q: Why does GEC24SABN-M30 have a wider operating temperature range?

A: The extended range (-65°C ~ 150°C versus -40°C ~ 105°C) reflects the substitute manufacturer's design specifications. This provides additional thermal margin and does not create compatibility issues for applications within the original part's temperature range.

Q: Are there any PCB layout considerations when switching to the substitute part?

A: No. Both connectors maintain identical pitch and position spacing. Existing PCB layouts and footprints require no modification for the GEC24SABN-M30 substitution.
