Substitute Part Grouping Explanation

Substitution for the M20-8902005 is determined by strict equivalence across the following critical parameters:

Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 20
Number of Rows: 1
Connector Type: Header configuration
Contact Type: Male Pin
Mounting Type: Surface Mount, Right Angle
Termination: Solder
Current Rating: 3A per Contact
Material Flammability Rating: UL94 V-0
RoHS Status: ROHS3 Compliant

Two substitute parts meet these criteria: M20-8902005R (Harwin Inc., Active status) and GBC20SBSN-M89 (Sullins Connector Solutions, Active status). Both maintain functional and electrical equivalence while offering active product status for continued availability.

Engineering Selection Recommendations

M20-8902005R is the primary substitute, offering direct equivalence as an active product from the original manufacturer Harwin Inc. This part maintains identical electrical and mechanical specifications, ensuring seamless integration into existing designs without modification.

GBC20SBSN-M89 from Sullins Connector Solutions serves as a secondary substitute. While functionally equivalent across critical parameters, minor dimensional variations exist: contact length mating is 0.230" (5.84mm) versus 0.236" (6.00mm), and insulation height is 0.140" (4.66mm) versus 0.136" (3.46mm). The Sullins part features an extended operating temperature range (-65°C to 150°C) and uses Phosphor Bronze contacts with PA9T insulation material, providing enhanced thermal performance. Both parts maintain ROHS3 compliance and UL94 V-0 flammability ratings.

Frequently Asked Questions (FAQ)

Q: Can M20-8902005R be used as a direct replacement for M20-8902005?

A: Yes. M20-8902005R is manufactured by Harwin Inc. and maintains identical specifications across all critical parameters including pitch, position count, mounting type, current rating, and operating temperature range. No design modifications are required.

Q: What are the key differences between M20-8902005R and GBC20SBSN-M89?

A: Both parts are functionally equivalent for the specified 2.54mm pitch, 20-position, surface mount right-angle header application. Differences include: contact material (Brass vs. Phosphor Bronze), insulation material (PA6T vs. PA9T), contact length mating (0.236" vs. 0.230"), insulation height (0.136" vs. 0.140"), and operating temperature range (-40°C to 105°C vs. -65°C to 150°C). The Sullins part offers extended thermal performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both M20-8902005R and GBC20SBSN-M89 are ROHS3 compliant with UL94 V-0 flammability ratings, matching the original M20-8902005 specifications.

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

A: Both designations refer to header configurations that allow individual positions to be separated. Cuttable headers are cut mechanically, while Breakaway headers feature designed break points. Both types are functionally compatible for this application.

Q: Which substitute should be selected for new designs?

A: M20-8902005R is recommended for designs requiring exact specification matching. GBC20SBSN-M89 is suitable when extended operating temperature range (-65°C to 150°C) is required or when Phosphor Bronze contact material is preferred for enhanced durability.
