Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M20-8902305 is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 23
• Number of Rows: 1
• Mounting Type: Surface Mount, Right Angle
• Contact Type: Male Pin
• Termination: Solder
• Fastening Type: Push-Pull
• Style: Board to Board or Cable
• Shrouding: Unshrouded

All substitute parts listed below maintain these core electrical and mechanical specifications. Variations in contact material, insulation material, contact finish thickness, and operating temperature range are permitted within the scope of equivalent substitution, as these parameters do not affect mating compatibility or primary functional performance in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status, ensuring long-term availability and manufacturing support. Each substitute meets ROHS3 compliance and UL94 V-0 flammability requirements, matching the regulatory profile of the original M20-8902305.

GBC23SBSN-M89 (Sullins Connector Solutions) provides the closest mechanical alignment with contact length of 0.230" (5.84mm) and insulation height of 0.140" (4.66mm), offering a direct functional replacement with extended operating temperature range (-65°C ~ 150°C) and specified current rating of 3A per contact.

TSM-123-01-L-SH-A-P-TR and TSM-123-01-L-SH-A-TR (Samtec Inc.) are differentiated by the inclusion of pick-and-place features in the former variant. Both feature Liquid Crystal Polymer insulation material and reduced insulation height of 0.120" (3.05mm), with operating temperature range of -55°C ~ 125°C. The board guide feature supports automated assembly processes.

Selection between these substitutes depends on application-specific requirements regarding insulation material compatibility, operating temperature envelope, and assembly methodology.

Frequently Asked Questions (FAQ)

Q: Can GBC23SBSN-M89 be used as a direct replacement for M20-8902305?

A: Yes. Both parts share identical pitch (0.100"), position count (23), row configuration (1), mounting type (surface mount right-angle), contact type (male pin), termination method (solder), and fastening type (push-pull). The GBC23SBSN-M89 maintains full mating compatibility with corresponding receptacles designed for the M20-8902305.

Q: What is the significance of the contact length difference between M20-8902305 (0.236") and the substitute parts (0.230")?

A: The 0.006" (0.15mm) difference in mating contact length falls within standard tolerance ranges for 0.100" pitch connectors and does not affect mating performance or electrical continuity. Both dimensions ensure proper contact engagement with standard receptacles.

Q: Are the Samtec TSM-123 variants interchangeable with each other?

A: TSM-123-01-L-SH-A-P-TR and TSM-123-01-L-SH-A-TR are mechanically and electrically identical. The primary distinction is the inclusion of pick-and-place features in the P-TR variant, which facilitates automated component placement during manufacturing. Selection between these variants depends on assembly process requirements.

Q: How do insulation material differences affect substitution?

A: The M20-8902305 uses Polyamide (PA6T) insulation, while GBC23SBSN-M89 uses Polyamide (PA9T), and Samtec variants use Liquid Crystal Polymer (LCP). All three materials meet UL94 V-0 flammability requirements and maintain electrical performance within standard operating conditions. Material selection should be evaluated against specific application environmental exposure and thermal cycling requirements.

Q: What is the impact of operating temperature range differences?

A: The M20-8902305 operates from -40°C to 105°C. GBC23SBSN-M89 extends this range to -65°C to 150°C, while Samtec variants operate from -55°C to 125°C. Selection of a substitute with extended temperature range provides additional design margin but is not required for applications within the original part's temperature envelope.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. M20-8902305, GBC23SBSN-M89, TSM-123-01-L-SH-A-P-TR, and TSM-123-01-L-SH-A-TR are all ROHS3 compliant, meeting regulatory requirements for restricted substance elimination in electronic components.
