Equivalent & Substitute Parts for M20-8901705

Part Overview

The M20-8901705 is a rectangular connector header manufactured by Harwin Inc., designed for surface mount, right-angle applications with 17 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement planning. The connector features male pins with gold-plated brass contacts, solder termination, and operates across -40°C to 105°C. Substitution becomes necessary due to product discontinuation while maintaining functional compatibility in board-to-board or cable connection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the M20-8901705 is determined by the following critical parameters that must align for functional compatibility:

Primary Substitution Criteria:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for connector interface compatibility
• Contact Type: Male Pin — maintains board-to-board or cable connection functionality
• Mounting Type: Surface Mount, Right Angle — ensures PCB assembly compatibility
• Termination: Solder — preserves assembly process compatibility
• Current Rating: 3A per Contact — maintains electrical performance requirements
• Operating Temperature Range: Must encompass or exceed -40°C ~ 105°C
• Material Flammability Rating: UL94 V-0 — meets safety and regulatory requirements
• RoHS Status: ROHS3 Compliant — ensures regulatory compliance

Substitute Parts Identified:

1. M20-8902005R (Harwin Inc.) — Direct manufacturer alternative with 20 positions, same pitch and electrical characteristics, active product status
2. GBC17SBSN-M89 (Sullins Connector Solutions) — Exact position count match (17 positions), identical pitch and mounting configuration, active product status

Both substitutes maintain the core electrical and mechanical parameters required for functional replacement while offering active product availability.

Parameter Comparison

Engineering Selection Recommendations

M20-8902005R Selection Criteria: This substitute is manufactured by Harwin Inc., the original equipment manufacturer, ensuring design continuity and supply chain consistency. The part maintains identical electrical and thermal specifications with the main part. The primary design consideration is the increased position count (20 vs. 17), which requires PCB layout modification to accommodate the additional connector positions. This substitute is recommended for applications where the extended connector capacity provides functional benefit or where design flexibility permits position count adjustment. Active product status ensures long-term availability and supply stability.

GBC17SBSN-M89 Selection Criteria: This substitute provides exact position count matching (17 positions) with the original part, minimizing PCB layout modifications. Manufactured by Sullins Connector Solutions, this part maintains all critical electrical parameters and compliance certifications. Minor mechanical variations exist: contact length differs by 0.006" (0.16mm), insulation height by 0.004" (0.10mm), and contact material composition differs (phosphor bronze vs. brass). The operating temperature range extends to -65°C ~ 150°C, providing enhanced thermal performance. Connector type classification differs (breakaway vs. cuttable), which may affect assembly or field modification procedures. Active product status ensures procurement availability. This substitute is recommended for applications requiring exact position count compatibility with minimal PCB redesign.

Compliance and Regulatory Basis: Both substitutes maintain ROHS3 compliance, UL94 V-0 flammability rating, and unlimited moisture sensitivity level (MSL 1), ensuring regulatory alignment with the original part. Selection between substitutes should prioritize application-specific requirements regarding position count, thermal operating range, and connector breakaway vs. cuttable functionality.

Frequently Asked Questions (FAQ)

Q: Can M20-8902005R be used as a direct replacement for M20-8901705?

A: M20-8902005R shares identical electrical and thermal specifications with the original part. However, the position count increases from 17 to 20, requiring PCB layout modification. Direct pin-for-pin substitution is not possible without design changes. This substitute is suitable for applications where the additional positions provide functional benefit or where PCB redesign is feasible.

Q: What are the key differences between GBC17SBSN-M89 and M20-8901705?

A: GBC17SBSN-M89 maintains the same 17-position count, pitch, mounting type, and current rating. Differences include: contact material (phosphor bronze vs. brass), insulation material (PA9T vs. PA6T), contact length variation of 0.006" (0.16mm), insulation height variation of 0.004" (0.10mm), and extended operating temperature range (-65°C ~ 150°C vs. -40°C ~ 105°C). Connector type differs (breakaway vs. cuttable), affecting field modification capabilities. These variations do not prevent functional substitution in standard applications.

Q: Are both substitutes compatible with existing PCB designs for M20-8901705?

A: GBC17SBSN-M89 provides direct mechanical and electrical compatibility with minimal PCB modification due to identical position count and pitch. M20-8902005R requires PCB layout changes to accommodate the additional three positions. Both maintain solder termination compatibility and surface mount, right-angle mounting configuration.

Q: Do the substitutes meet the same regulatory and compliance standards?

A: Both substitutes maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level, matching the original part's regulatory profile. Operating temperature ranges differ, with GBC17SBSN-M89 providing extended thermal performance.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For designs requiring exact position count compatibility with minimal PCB modification, GBC17SBSN-M89 is appropriate. For applications where additional connector positions provide functional benefit or where design flexibility permits layout changes, M20-8902005R offers manufacturer continuity with Harwin Inc. Both parts are active products with established supply availability.

Q: What is the significance of the connector type difference (cuttable vs. breakaway)?

A: Cuttable connectors allow field modification by cutting individual positions from the connector strip. Breakaway connectors feature pre-scored sections for position separation. This difference affects assembly procedures and field modification capabilities but does not impact electrical or thermal performance in standard applications.
