TSM-104-01-S-SV-P Equivalent & Substitute Parts

Part Overview

The TSM-104-01-S-SV-P is a surface mount rectangular connector header manufactured by Samtec Inc. This 4-position connector operates at 0.100" (2.54mm) pitch and features a cuttable design suitable for board-to-board or cable applications. The part is actively produced and maintains robust inventory availability. Equivalent parts are identified when design flexibility, supply chain optimization, or manufacturing process changes require alternative component selection while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

The M20-8770442 manufactured by Harwin Inc. qualifies as a functional equivalent based on the following critical parameters:

• Identical connector type classification (Header, Cuttable)
• Matching contact type (Male Pin)
• Identical mating pitch (0.100" / 2.54mm)
• Identical position count (4 positions, 1 row)
• Identical mounting method (Surface Mount)
• Identical termination method (Solder)
• Identical fastening type (Push-Pull)
• Matching contact shape (Square)
• Identical contact finish on mating surface (Gold)
• Identical contact finish on post (Tin)
• Matching insulation height (0.100" / 2.54mm)
• Identical shrouding classification (Unshrouded)
• Identical style (Board to Board or Cable)
• Both parts maintain ROHS3 compliance and UL94 V-0 flammability rating

Substitution is valid where the operating temperature range and insulation material differences are acceptable within the application's design constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the TSM-104-01-S-SV-P and M20-8770442 maintain active product status and full ROHS3 compliance with UL94 V-0 flammability certification. Selection between these parts depends on application-specific requirements:

The TSM-104-01-S-SV-P supports an extended operating temperature range of -55°C to 125°C and uses Liquid Crystal Polymer insulation material. This configuration is suitable for applications requiring broader thermal performance.

The M20-8770442 operates within -40°C to 105°C and employs Polyamide (PA6T) Nylon 6T insulation. This part specifies a current rating of 3A per contact and is packaged in bulk format. Selection of this substitute is appropriate where the narrower temperature range and specified current rating align with application parameters.

Both parts share identical mechanical and electrical interface characteristics, including mating pitch, position count, contact geometry, and termination method. The contact material difference (Phosphor Bronze versus Brass) and insulation material variation do not affect functional compatibility at the connector interface level.

Frequently Asked Questions (FAQ)

Q: Can M20-8770442 be used as a direct replacement for TSM-104-01-S-SV-P?

A: Yes, within application constraints. Both connectors share identical mating pitch (2.54mm), position count (4), contact type (Male Pin), mounting method (Surface Mount), and termination (Solder). Compatibility is confirmed where the operating temperature range of -40°C to 105°C and Polyamide insulation material are acceptable for the application.

Q: What are the key differences between these two parts?

A: The primary differences are operating temperature range (TSM-104-01-S-SV-P: -55°C to 125°C versus M20-8770442: -40°C to 105°C), insulation material (Liquid Crystal Polymer versus Polyamide), contact material (Phosphor Bronze versus Brass), and packaging format (Tube versus Bulk). Contact length specifications differ marginally (0.230" versus 0.228").

Q: Are both parts RoHS compliant?

A: Yes. Both TSM-104-01-S-SV-P and M20-8770442 are ROHS3 compliant and maintain UL94 V-0 flammability certification.

Q: What is the current rating for these connectors?

A: The M20-8770442 specifies 3A per contact. The TSM-104-01-S-SV-P does not provide a current rating specification in available documentation.

Q: Does packaging format affect connector performance?

A: No. The TSM-104-01-S-SV-P is supplied in Tube packaging while M20-8770442 is supplied in Bulk packaging. Packaging format affects handling and inventory management but does not alter connector electrical or mechanical performance.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
