Key Parameters

Substitute Part Grouping Explanation

Substitution of the M20-8772242 is determined by strict equivalence across the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 22
• Number of Rows: 1
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Insulation Height: 0.100" (2.54mm)
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical requirements. Variations in contact material, insulation material, contact finish specifications, and operating temperature ranges are secondary parameters that do not preclude substitution when primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and MSL 1 rating, meeting the regulatory and environmental requirements of the M20-8772242. Selection among substitutes depends on specific application requirements:

GBC22SABN-M30 (Sullins Connector Solutions) provides the widest operating temperature range (-65°C to 150°C) and is available in bulk packaging, suitable for high-volume production environments.

TSM-122-01-F-SV-LC (Samtec Inc.) and TSM-122-01-F-SV-LC-P-TR (Samtec Inc.) feature Board Lock functionality and Liquid Crystal Polymer insulation, with the latter available in Tape & Reel packaging for automated assembly. Operating temperature range is -55°C to 125°C.

TSM-122-01-L-SV (Samtec Inc.) is packaged in Tube format and offers the highest inventory availability among Samtec options.

TSM-122-01-S-SV-P-TR (Samtec Inc.) and TSM-122-01-S-SV-A-P-TR (Samtec Inc.) are Tape & Reel packaged variants with Pick and Place features. The latter includes Board Guide functionality.

TSM-122-01-G-SV-P-TR (Samtec Inc.) features gold plating on both mating and post contacts, providing enhanced corrosion resistance compared to standard tin post finishes.

TSM-122-01-T-SV-LC-P-TR (Samtec Inc.) uses tin mating contact finish instead of gold, with Board Lock and Pick and Place features.

Frequently Asked Questions (FAQ)

Q: Can GBC22SABN-M30 be used as a direct replacement for M20-8772242?

A: Yes. Both connectors share identical pitch (0.100"), position count (22), row configuration (1), mounting type (surface mount), termination method (solder), and fastening type (push-pull). The GBC22SABN-M30 features Breakaway connector type versus Cuttable on the original, but this does not affect electrical or mechanical compatibility. The substitute offers superior operating temperature range (-65°C to 150°C versus -40°C to 105°C).

Q: What is the difference between Samtec TSM-122 variants?

A: Samtec TSM-122 variants differ in insulation material, contact finish specifications, and packaging format. TSM-122-01-F-SV-LC uses Liquid Crystal Polymer insulation with Board Lock. TSM-122-01-S-SV-P-TR uses the same insulation with Pick and Place features. TSM-122-01-L-SV is packaged in Tube format. TSM-122-01-G-SV-P-TR features gold post finish. TSM-122-01-T-SV-LC-P-TR uses tin mating finish. All maintain the core 22-position, 0.100" pitch, surface mount solder configuration.

Q: Are there packaging considerations when selecting a substitute?

A: Yes. GBC22SABN-M30 is supplied in Bulk packaging. Samtec TSM-122-01-F-SV-LC-P-TR, TSM-122-01-F-SV-P-TR, TSM-122-01-S-SV-A-P-TR, TSM-122-01-S-SV-P-TR, and TSM-122-01-T-SV-LC-P-TR are Tape & Reel packaged for automated pick-and-place assembly. TSM-122-01-L-SV is Tube packaged. Selection should align with production assembly methodology and inventory management requirements.

Q: Does the contact material difference (Brass versus Phosphor Bronze) affect substitution?

A: Contact material is a secondary parameter. All listed substitutes use Phosphor Bronze contacts versus Brass in the original M20-8772242. This material change does not preclude substitution, as Phosphor Bronze provides equivalent electrical conductivity and mechanical durability for the specified 3A current rating and push-pull fastening application.

Q: Which substitute offers the best thermal performance?

A: GBC22SABN-M30 supports the widest operating temperature range at -65°C to 150°C, compared to -55°C to 125°C for most Samtec variants and -55°C to 105°C for TSM-122-01-T-SV-LC-P-TR. Selection depends on specific application thermal requirements.
